<p>Look out over the desert east of Aswan in southern Egypt, and it might seem like there’s nothing but rocks and sand - no sign of the kings who once ruled here. But look closer, and the walls start talking.</p>



<p>Thousands of years ago, long before the famous pharaohs ruled from pyramids, kings carved their power into stone.</p>



<p>These carvings weren’t just decorations. They were public declarations of who was in charge. And they’ve finally gotten the attention they deserve.</p>



<h2 class="wp-block-heading" id="h-lost-rulers-carved-into-stone">Lost rulers carved into stone</h2>



<p>More than 5,000 years ago, <a href="https://www.earth.com/news/solar-eclipse-may-have-changed-the-architecture-of-ancient-egypt-forever/">Egypt</a> was on the edge of something big. Small local rulers had started forming a more connected and controlled territory. </p>



<p>The place we now call Egypt was becoming the world’s first territorial state. It stretched about 500 miles from north to south. That’s not small for a place that had no highways or phones - just boats, legs, and grit.</p>



<p>In the <a href="https://www.earth.com/news/850-paleolithic-artifacts-discovered-with-the-naked-eye-in-a-desert/">desert</a> valleys like Wadi el Malik and Wadi Abu Subeira, rulers made their presence known with carvings. One of the most fascinating figures from this time was a ruler called Scorpion. </p>



<p>His name appears in rock inscriptions along with a few other symbols, including one that marks it as a place name.</p>



<p>That particular place-name sign is believed to be the oldest one ever found. That discovery made international headlines a few years back. Now, there’s more.</p>



<h2 class="wp-block-heading" id="h-egypt-s-lineup-of-early-kings">Egypt's lineup of early kings</h2>



<p>Scorpion wasn’t alone. The rocks tell the story of other rulers too. There’s King Bull, who came before him, and Horus-Falcon, who may have been the first in this royal line. </p>



<p>Some of their names reference dangerous animals - <a href="https://www.earth.com/image/centipede/">centipedes</a>, falcons, bulls - creatures that symbolized strength and fear.</p>



<p>This lineup of names and animal symbols is what researchers call a "royal rock art tableau." It's not just a list - it’s a way to show power, legacy, and control over a tough, rugged landscape. These kings wanted people in Egypt to know: This land is ours. We rule here.</p>

<h2 class="wp-block-heading" id="h-violence-and-power-on-display">Violence and power on display</h2>



<p>These carvings didn’t shy away from violence. One scene shows a ruler standing over a fallen enemy. In the background, two decapitated heads leave no doubt about the message. These weren’t peaceful monuments - they were warnings.</p>



<p>“The most extreme scene is the one showing the ruler trampling an enemy, with two decapitated heads visible in the background,” said Egyptologist Professor Dr. Ludwig Morenz from the <a href="https://www.uni-bonn.de/" target="_blank" rel="noreferrer noopener">University of Bonn</a>, who has been studying these carvings with his colleague Mohamed Abdelhay Abu Bakr.</p>



<h2 class="wp-block-heading" id="h-kings-carved-ties-to-egypt-s-gods">Kings carved ties to Egypt's gods</h2>



<p>The kings from this period didn’t call themselves gods. But they made it clear they were close. </p>



<p>They aligned themselves with two powerful deities from the <a href="https://www.earth.com/news/ancient-human-highways-revealed-beneath-the-sea/">Nile Valley</a> - Bat, a celestial cow often shown with a star-covered face, and Min, a hunting god tied to the deserts and outer regions.</p>



<p>“They formed a divine couple, with Bat associated with the fertile land along the Nile and Min with the peripheral regions as a kind of hunting god,” Morenz said.</p>



<p>The connection to these gods helped build something called “pharaoh-fashioning.” This was how early rulers shaped their image - as chosen leaders backed by divine power. They didn’t inherit power quietly. They carved it in stone.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/08/ancient-egypt_rock-art_ruler-defeating-enemies_credit-Johann-Thiele_1m.jpg"><img src="https://www.earth.com/wp-content/uploads/2025/08/ancient-egypt_rock-art_ruler-defeating-enemies_credit-Johann-Thiele_1s.webp" alt="Combined with the motif of defeating enemies.

<h2 class="wp-block-heading" id="h-trade-and-faith-carved-together">Trade and faith carved together</h2>



<p>At the time, this region was more than desert. It had resources, water, and wildlife. People passed through on hunting trips or mineral expeditions. That made it valuable - and contested. It also made it the perfect spot to mark territory.</p>



<p>“It is actually all about a grandiose presentation of the claim to sovereignty,” Morenz said.</p>



<p>And part of that grand display included religion. One large carving shows a "boat of the gods" being hauled by 25 men. This likely represents a sacred procession that tied the desert valley to the better-known Nile Valley.</p>

<h2 class="wp-block-heading" id="h-desert-valleys-served-as-crossroads">Desert valleys served as crossroads</h2>



<p>These carvings aren’t easy to see with the naked eye. Thousands of years of wind and sand have taken their toll. But new digital tools have made a difference. </p>



<p>Researchers used high-powered photo analysis to reveal carvings that would otherwise go unnoticed.</p>



<p>“This is an important region when it comes to our understanding of the emergence of the state at the sociocultural periphery in the late fourth millennium,” Morenz said.</p>



<p>It’s clear there's more to learn here. Compared to central Egypt, this area has barely been studied. But it played a major role in shaping one of the most influential <a href="https://www.earth.com/news/worlds-oldest-calendar-discovery-could-rewrite-history-of-civilization/">civilizations</a> in history.</p>



<h2 class="wp-block-heading" id="h-modern-scans-revived-ancient-history">Modern scans revived ancient history</h2>



<p>Morenz hopes this area will get the attention it deserves. That means more research, bigger projects, and maybe even making the site accessible to visitors.</p>



<p>“I consider this so important that this hot spot should also be made accessible to interested parties with tours and a visitor center,” he said.</p>



<p>What was once forgotten desert might soon become one of Egypt’s most important historical windows. Not just because of what’s carved in stone - but because of what it shows about the earliest rulers who helped create a state that would shape human history.</p>

On Aug. 1 at 11p.m. EDT (Aug. 2 3 a.m. UTC) the Joint Typhoon Warning Center issued its final bulletin on Typhoon Nida. By that time, Nida had already made landfall and was located about 49 nautical miles northwest of <a href="http://www.earth.com/news/hong-kong-japan-iceland-human-development/">Hong Kong</a>, near 22.8 degrees north latitude and 113.5 degrees east longitude. Nida was moving to the west-northwest. Maximum sustained winds were near 74.8 mph (65 knots/120.4 kph) making it a Category 1 hurricane on the Saffir-Simpson Wind Scale.

At 11:05 p.m. EDT (Aug. 2 at 3:05 a.m. UTC) the Moderate Resolution Imaging Spectroradiometer aboard NASA's Terra satellite captured a visible image of Typhoon Nida after it made landfall near Hong Kong, China. The image showed the center of Nida north of Hong Kong, and the eye had become cloud-filled. A strong band of thunderstorms extended to the southwest of the center to Hainan Island.

By 4 p.m. Hong Kong local time on Aug. 2, Nida had weakened to a tropical storm. Nida was located 149 miles (240 km) northwest of Hong Kong and forecast to move to the northwest. Hong Kong Observatory will cancel warnings later today, but advises residents to stay away from the shoreline. To hear the forecast from Aug. 2, 2016, visit: <a href="http://www.hko.gov.hk/wxinfo/currwx/briefing/report_e.mp3?20160802121504" target="_blank" rel="noopener noreferrer">http://www.<wbr />hko.<wbr />gov.<wbr />hk/<wbr />wxinfo/<wbr />currwx/<wbr />briefing/<wbr />report_e.<wbr />mp3?20160802121504</a>.

Nida made landfall near Hong Kong and no major damage was reported in the city. The Hong Kong Observatory reported that some areas of the city noted reports of winds of up to 90 mph (145 kph).

The storm is moving to inland areas of Guangdong and further inland where it is expected to dissipate.

<div>The diversity of climates in mountain landscapes means that when temperatures rise, organisms might have to only move a short distance to get to a cooler home.. New research by University of <a href="http://www.earth.com/earthpedia-articles/montana-valley-and-foothill-grasslands/">Montana</a> forest landscape ecology Professor Solomon Dobrowski shows that organisms will face more hardships as they relocate when climate change makes their current homes uninhabitable.</div>
<div>

Dobrowski and co-author Sean Parks -- a scientist at the U.S. Department of Agriculture, Forest Service Aldo Leopold Research Institute and a UM alumnus -- propose a new method to model how fast and where organisms will need to move to keep pace with climate change. Study: Mountain landscapes are extremely vulnerable to climate change

Mountains support roughly a quarter of the globe's terrestrial biodiversity, contain about a third of its protected areas and house nearly half of the world's biodiversity hotspots. One reason for this biodiversity is that complex topography within mountains creates diverse climates within close proximity to one another.

One way scientists measure how vulnerable a site is to climate change is to estimate how far organisms at that site need to move to maintain a consistent temperature as the Earth warms. The diversity of climates in mountain landscapes means that when temperatures rise, organisms might have to only move a short distance to get to a cooler home.

However, Dobrowksi and Parks show that measuring the distance from one area of suitable climate to the next doesn't account for the resistance organisms will encounter as they traverse areas with very different climates, like a warm valley between two mountain peaks.

"It's not enough to just measure how far an organism will have to move in order to keep up with climate change," Dobrowski said. "We also need to look at how much organisms will be exposed to dissimilar climates along the way. Once we do that, we find that even short movements in mountainous areas expose organisms to large climate differences. This may prevent plants and animals from being able to maintain a suitable climate as the earth warms."

Dobrowski and Parks suggest that areas within mountains are more climatically isolated and thus more vulnerable to climate change than previously reported.
<p align="center">###</p>
Their paper "Climate change velocity underestimates climate change exposure in mountainous regions" was published Aug. 1 in <em>Nature Communications</em>.

<div class="img-wrapper">Tree cover on agricultural land has increased across the globe. While tropical forests continued to decline, a remarkable change is happening: tree cover on agricultural land has increased across the globe, capturing nearly 0.75 Gigatonnes carbon dioxide every year. A new study titled <a href="http://www.nature.com/articles/srep29987" target="_blank" rel="noopener">"Global Tree Cover and Biomass Carbon on Agricultural Land: The contribution of agroforestry to global and national carbon budgets"</a> provides insights into the patterns of this tremendous change at global, regional and national scales.</div>
According to the International Panel on Climate Change (IPCC), agriculture and land-use change account for about 24% of the world's greenhouse gas emissions. Climate change will also have strong impacts on food security in the long-term. Therefore agriculture needs to reduce its climate footprint. But a recent study has shown that the potential to reduce greenhouse gas emissions from crop and livestock production is limited. At the same time, large forest areas, primarily in the tropics, are still being converted into agricultural land to feed the world's growing population.

For these reasons, agricultural practices that can significantly reduce carbon emissions are in high demand.

Trees on agricultural lands - also known as agroforestry systems - have the potential to contribute to climate change mitigation while improving livelihoods and incomes and providing invaluable ecosystem services at the same time. The World Bank estimates that globally 1.2 billion people depend on agroforestry farming systems, especially in developing countries. However, trees on agricultural lands are not considered in the greenhouse gas accounting framework of the IPCC.

A team of researchers from various institutions in Africa, Asia and Europe carried out a study to assess the role of trees on agricultural land and the amount of carbon they have sequestered from the atmosphere over the past decade. The study, entitled <a href="http://www.nature.com/articles/srep29987" target="_blank" rel="noopener">"Global Tree Cover and Biomass Carbon on Agricultural Land: The contribution of agroforestry to global and national carbon budgets"</a>, looks at biomass carbon on agricultural land both globally and by country, and what determines its distribution across different climate zones.

<strong>Biomass on agricultural land globally</strong>

"Remote sensing data show that in 2010, 43% of all agricultural land globally had at least 10% tree cover, up from eight percent in the preceding decade," said Robert Zomer of the World Agroforestry Centre, lead author of the study. "Given the vast amount of land under agriculture, agroforestry may already significantly contribute to global carbon budgets."

However, regional differences in the trend are significant. The distribution of tree cover on agricultural land depends on climatic conditions in different parts of the world. High tree cover is found in humid areas such as South East Asia, Central America, eastern South America, as well as central and coastal West Africa. Tree cover on agricultural land was moderate in south Asia, sub-humid Africa, central and western Europe, the Amazonia and mid-west North America. On the other hand, low tree cover was found in east China, northwest India, west Asia, the southern border of the Sahara Desert, the prairies of North America and southwest Australia.

<strong>Biomass on agricultural land by country</strong>

Remarkable differences are noted in changing biomass carbon stocks over time among countries. Brazil, Indonesia, China and India had the largest increases, while Argentina, Myanmar, and Sierra Leone had the largest decreases in biomass carbon stored on agricultural land.

High average carbon mass levels were to be found in 26 countries in the humid tropics, with the Democratic Republic of Congo, Papua New Guinea, Malaysia and <a href="http://www.earth.com/news/indonesian-forests-disturbed-by-humans-are-highly-flammable/">Indonesia</a> in the lead. On the other hand, 60 countries found in arid and desert parts of the world around the Sahara Desert in North Africa, the Kalahari in southern Africa, Middle East, as well as central and southern Asia recorded low carbon levels over the ten-year period. Tree cover on agricultural land has increased across the globe

"Study results show that existing tree cover makes a major contribution to carbon pools on agricultural land, demonstrating the potential to add to climate change mitigation and adaptation efforts," said Jianchu Xu of the World Agroforestry Centre. "If tree cover is accounted for, the total carbon stock is over four times higher than when estimated using IPCC tier 1 estimates alone."

Given the large amount of agricultural land where tree cover is below its potential, the study suggests that a huge mitigation potential exists and should be explored more systematically.

"The results of our spatial analysis show that trees on agricultural land sequestered close to 0.75 Gigatonnes of carbon dioxide globally per year over the past decade," said Henry Neufeldt, Head of Climate Change research at the World Agroforestry Centre. "If we can harness good policies to enhance positive examples and stop negative trends, trees in agricultural landscapes can play a major role in greenhouse gas mitigation. But no one should say that this is already solving the problem for agricultural emissions as long as we do not know what is actually happening on the ground."

<div>Study: Soil contains twice as much carbon as the atmosphere. There is more than twice as much carbon in the planet's soils than there is in its atmosphere, so the loss of even a small proportion of that could have a profound feedback effect on the global climate.</div>
<div>

Yet in its most recent report, in 2013, the Intergovernmental Panel on Climate Change (IPCC) used models that paid less attention to soil carbon potentially entering the atmosphere than had earlier reports, concluding that there simply wasn't enough evidence about how warmer global temperatures might impact soil carbon stocks.Study: Soil contains twice as much carbon as the atmosphere

A new Yale-led paper makes the case that developing meaningful climate projections will rely on understanding the role of "soil carbon turnover" and how it might potentially trigger climate feedbacks in a warming world.

Writing in the journal <em>Nature Climate Change</em>, a team of scientists calls for more collaboration between modelers and soil scientists to improve the scientific understanding of the mechanisms that control the creation, stabilization, and decomposition of carbon in the soil.

That in turn will promote the kinds of experiments that will begin to remove uncertainties about the competing mechanisms that drive soil carbon stocks, the researchers write.

While scientists might never eliminate all uncertainty when it comes to evaluating the mechanisms driving changes in soil carbon stocks, new research advances are making it possible to predict the full range of potential outcomes, said Mark Bradford, an Associate Professor of Terrestrial Ecosystem Ecology at the Yale School of Forestry &amp; Environmental Studies (F&amp;ES) and lead author of the study.

And that, he says, will increase confidence.

"There is so much discussion of uncertainty in the public debate about climate change that the term now seems ambiguous and politically loaded," Bradford said. "The discussion should not be about how much uncertainty there is, but rather about how much confidence we have that the real planetary response lies somewhere in the range of projected uncertainty."

"You gain scientific confidence by representing the best -- and sometimes polar opposite -- ideas about the how the world works in your models. If someone tells you they have high confidence that something will happen, you can then take actions based on the best knowledge available."

Warming temperatures can trigger two very different changes in soil carbon soil levels. On the one hand, they can stimulate the growth of plants, increasing the amount of carbon storage potential. Conversely, those higher temperatures can also accelerate the activity of organisms that live in the soil and consume decaying plant matter. In that case, there is a net increase in the amount of <a href="http://www.earth.com/video/carbon-is-the-basis-for-all-life-on-our-planet/">carbon</a> released from the biosphere into the atmosphere.

In other words, one function puts carbon into the soil, keeping it out of the atmosphere, while the other emits it into the atmosphere. The twist, however, is that the processes that emit carbon from the soil also convert a small fraction of the decaying plant matter into stores of carbon that can be locked away over millennial timescales, which would be optimal to minimizing climate impacts.

While scientists have made great advances in understanding how plants will respond, their ability to evaluate how much carbon goes into the soil, and where it ends up, is made difficult because it's not possible to measure directly.

"In the soil, we don't know how things are working because, if you like, it's as clear as mud," Bradford said. "Often we can't measure what we're trying to measure because we can't see the organisms. You have millions of individual microbes -- from thousands of cryptic species -- in just a handful of soil."

For these reasons, he said, much of the understanding of how soil carbon stocks will respond to warming is based only on the outputs, which is like trying to calculate the balance of a bank account based simply on how much money is being withdrawn.

Another complicating factor is that our knowledge of how soil carbon is created and stabilized is undergoing somewhat of a conceptual revolution, and only one set of ideas is represented in the climate models, the new paper says. For decades scientists assumed that carbon entering the soil through materials that are harder to "digest" by microbes -- like, say, wood -- would be more likely to remain in the soil longer.

In recent years, however, there has emerged a growing consensus that carbon is more likely to remain in the soil if it enters through more digestible plant matter -- a cloverleaf, for instance. "The science has flipped," Bradford said. "The harder it is to digest initially the less of it stays in the soil, whereas the easier it is to be eaten then the more of it stays in the soil."

This is important because it's the easily digestible plant matter -- such as the sugars released from plant roots into the soil -- that likely eventually get converted into the long term stores of soil carbon but they are also the hardest inputs to quantify.

This growing awareness shifts the way scientists view ecosystem management, from thinking about the biomass that you can see aboveground to a focus on thinking about the amount of carbon that can be pumped belowground directly through the roots of the plants and to the organisms in the soils.

Ultimately, Bradford says, it will be impossible to eliminate all uncertainty. But that, he says, is not such a bad thing.

"By increasing our real understanding, we might even end up making our climate projections more uncertain, in terms of a greater range in the extent the planet might warm," he said. "But we'll be more confident that the true answer falls within that range."

"Advancing our confidence and taking necessary actions will ultimately require that we embrace uncertainty as a fact of life."

Study: Soil contains twice as much carbon as the atmosphere

Study: Soil contains twice as much carbon as the atmosphere....

Earth's fever got worse last year, breaking dozens of climate records, scientists said in a massive report nicknamed the annual physical for the planet. Earth's annual physical: Fever continues to rise

Soon after 2015 ended, it was proclaimed the hottest on record . The new report shows the broad extent of other records and near-records on the planet's climatic health. Those include record heat energy absorbed by the oceans and lowest groundwater storage levels globally, according to Tuesday's report from the National Oceanic and Atmospheric Administration.

"I think the time to call the doctor was years ago," <a href="https://en.wikipedia.org/wiki/NASA">NOAA</a> climate monitoring chief Deke Arndt, co-editor of the report, said in an email. "We are awash in multiple symptoms."

The 2015 State of the Climate report examined 50 different aspects of climate , including dramatic melting of Arctic sea ice and glaciers worldwide. A dozen different nations set hottest year records, including Russia and China. South Africa had the hottest temperature ever recorded in the month of October: 119.1 degrees Fahrenheit (48.4 degrees Celsius).

Even though it was a relatively quiet hurricane year in the <a href="http://www.earth.com/image/the-namib-desert-on-the-atlantic-coast/">Atlantic</a>, there were 36 major tropical cyclones worldwide - 15 more than average, said NOAA climate scientist Jessica Blunden, co-editor of the report published Tuesday in the Bulletin of the American Meteorological Society.Earth's annual physical: Fever continues to rise

And at the heart of the records is that all three major heat-trapping greenhouse gases - carbon dioxide, methane and nitrous oxide - hit record highs in 2015, Blunden said.

"There is really only one word for this parade of shattered climate records: grim," said Georgia Tech climate scientist Kim Cobb, who wasn't part of the report, but called it "exhaustive and thorough."

But it's more than just numbers on a graph. Scientists said the turbo-charged climate affected walrus and penguin populations and played a role in dangerous algae blooms, such as one off the Pacific Northwest coast. And there were brutal heat waves all over the world, with ones in Indian and Pakistan killing thousands of people. One-third of Earth's land mass had some kind of drought last year.

Much of the intense record-breaking and record-flirting weather was because of a combination of a natural El Nino - the periodic warming of parts of the Pacific that changes weather globally - and ever increasing man-made global warming.

"This impacts people. This is real life," Blunden said.

Oklahoma University meteorology professor Jason Furtado said in an email that the report, which he wasn't part of, illustrates the combined power of nature and humans on Earth's climate: "It was like injecting an already amped-up climate system with a dose of (natural) steroids."

About 450 scientists from around the world helped write the report and in it NOAA highlighted one of the lesser-known measurements, ocean heat content. About 93 percent of the heat energy trapped by greenhouse gases - such as carbon dioxide from the burning of coal, oil and gas - goes directly into the ocean, the report said. And ocean heat content hit record levels both near the surface and deep.

NOAA oceanographer Gregory C. Johnson, a study co-author, said the oceans are storing more heat energy because of man-made climate change with an extra El Nino spike.

Johnson summed up Earth's climate in a haiku, published deep inside the report:

"El Niño waxes,

warm waters shoal, flow eastward,

Earth's fever rises."

Earth's annual physical: Fever continues to rise

Earth's fever got worse last year, breaking dozens of climate...

<div>Early snowmelt reduces CO2 absorption in forests. Early snowmelt periods associated with a warming climate may hinder subalpine forest regulation of atmospheric carbon dioxide (CO<sub>2</sub>), according to the results of a new University of Colorado Boulder study.</div>
<div>

The findings, which were recently published in the journal <em>Geophysical Research Letters</em>, predict that this shift in the timing of the snowmelt could result in a 45 percent reduction of snowmelt period forest carbon uptake by mid-century.

A separate study, also published in Geophysical Research Letters, found that earlier, slower snowmelt reduces the amount of streamflow, a phenomenon with potentially drastic consequences for agriculture, municipal water supplies and recreational opportunities in <a href="http://www.earth.com/news/extra-water-colorado-river-endangered-fish/">Colorado</a> and other areas of the western U.S.

Forests located in seasonally snow-covered areas represent a key terrestrial CO<sub>2</sub> sink thanks to the natural photosynthetic processes by which trees uptake carbon. The trees' carbon uptake is restrained during winter, but increases to peak capacity in spring when snowmelt provides sustained water input.

Working at the Niwot Ridge Ameriflux site in Colorado's Rocky Mountains, CU Boulder researchers studied 15 years' worth of snowmelt and atmospheric CO<sub>2</sub> data to study the effects of snowmelt periods. The research found that earlier snowmelt periods triggered by climate change align with colder air temperatures, reducing the forests' ability to take CO<sub>2</sub> out of the atmosphere.

"This study shows us that, counterintuitively, warming generally causes snow to melt during colder periods of the seasonal temperature cycle due to the effects that warming has on reducing the depth of snowpacks, which causes melt to begin earlier in the year," said Taylor Winchell, a graduate researcher in the Institute for Arctic and Alpine Research (<a href="https://en.wikipedia.org/wiki/NASA">INSTAAR</a>) and lead author of the study. "The colder temperatures associated with early melt reduce the trees' ability to uptake carbon during the snowmelt period, a key period for seasonal carbon uptake."

"The implications of this research are quite profound as mountains in the western U.S. are an important part of the regional cycling of carbon and water," said Noah Molotch, the director of the Center for Water Earth Science &amp; Technology (CWEST) and a co-author of both new studies. "In this regard, earlier snowmelt will reduce carbon uptake in mountain forests, weakening the ability of forests to offset increases in CO<sub>2</sub> associated with human burning of fossil fuels."

Snowmelt also acts as a key hydrological driver for rivers and streams across the state, providing water resources to downstream communities. Previous research has suggested that the timing and rate at which snow melts can impact the amount and quality of water available for vegetation, farming, and fishing.

The researchers used a unique modeling system to study the effects of earlier snowmelt across various regions of western United States including the Cascade range, the Sierra Nevada range, the Wasatch range, and the Rocky Mountains. All of these areas see significant seasonal snow accumulation and generate water resources for downstream communities.

The study results show that earlier, slower snowmelt, triggered by warmer temperatures, reduce streamflow. These slower "trickle" melts reduce percolation in hillslope soil and allow more water to evaporate, resulting in less streamflow overall.

"Of all the regions we studied, streamflow from Colorado's Rocky Mountains is most sensitive to a change in snowmelt," says Theodore Barnhart, a graduate researcher at INSTAAR and lead author of the study. "This analysis suggests that all of the regions studied will experience a decrease in streamflow with a decrease in snowmelt rate, with some regions exhibiting more streamflow sensitivity than others."

"The recent western drought has been accompanied by a snowpack restricted to higher elevations, with a significant effect on the ski industry," says Tom Torgersen, program director in the National Science Foundation (NSF)'s Division of Earth Sciences, which funded the research. "Climate variability also leads to conditions favoring earlier and slower snowmelt, with a decreased and prolonged peak streamflow. This water flow affects mountain fishing and results in less forest growth. The effects of drought and climate variability reach far beyond farm productivity and urban water restrictions."

"Given that 60 million people in the western U.S. depend on snowmelt for their water supply, the future decline in snowmelt-derived streamflow may place additional stress on over-allocated water supplies," said Molotch.

"There is a similar theme in these two studies: 'colder forests in a warmer world' and 'slower snowmelt in a warmer world.' Both phenomena defy expectations," Molotch added. "In this regard, these studies are reshaping the way scientists and land and water managers think about climate change in mountainous regions."

The work was funded by the NSF, the U.S. Department of Energy, the U.S. Department of Agriculture and the Niwot Ridge Long-Term Ecological Research Program.

Infrared data from NASA's Terra satellite has revealed that Tropical Storm Howard is weakening quickly as it continues to move over cooler waters in the Eastern <a href="http://www.earth.com/news/dust-asia-fertilizes-north-pacific/">Pacific Ocean.</a></div>
On Aug. 3 at 2:35 a.m. EDT (6:35 a.m. UTC) the Moderate Resolution Imaging Spectroradiometer, or <a href="https://www.bing.com/search?q=modis&amp;form=EDGEAR&amp;qs=PF&amp;cvid=58793ca96fb04ccfa017ca18b8813a35&amp;cc=US&amp;setlang=en-US&amp;plvar=0&amp;PC=HCTS">MODIS</a>, instrument that flies aboard NASA's Terra satellite provided infrared data on Howard. The image showed that strong thunderstorms and deep convection (rising air that forms them) continued to decrease and were limited to northwest and south of the center. The National Hurricane Center (NHC) reported that the strongest storms had become separated from the low-level center of the storm overnight. Tropical Storm Howard and Tropical Depression Ivette

At 5 a.m. EDT (9 a.m. UTC) on Aug. 3, the center of Tropical Storm Howard was located near 20.3 degrees north latitude and 132.6 degrees west longitude. That's about 1,465 miles (2,360 km) west of the southern tip of Baja California, Mexico. Howard was moving toward the west-northwest near 15 mph (24 kph), and this motion should continue through today. A turn toward the west is expected by Thursday. Maximum sustained winds have decreased to near 45 mph (75 kph) and is forecast to continue weakening. The estimated minimum central pressure is 1,005 millibars.

In the Tropical Storm Howard Discussion online at 5 a.m. EDT, National Hurricane Center forecaster Daniel Brown said, "The tropical storm should continue to weaken during the next day or so while it moves over cool water and into a drier and more stable environment. Howard is forecast to become a remnant low in 24 to 36 hours, but this could occur sooner if organized deep convection does not redevelop later today."

The seventh tropical cyclone of the Northwestern Pacific Ocean season formed, and infrared data from <a href="https://en.wikipedia.org/wiki/NASA">NASA</a>'s Aqua satellite showed powerful thunderstorms persisting in the storm's center.</div>
The Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument that flies aboard NASA's Aqua satellite captured infrared temperature data of the newly developed tropical storm on Aug. 4, 2016, at 8:10 a.m. EDT (12:10 p.m. UTC). The<a href="http://www.earth.com/image/winter-caucasus-mountains-russia/"> MODIS</a> data showed cloud top temperatures of strong thunderstorms around the center of circulation as cold as minus 80 F (minus 62.2 C). Temperatures that cold indicate strong uplift in the storm and cloud tops high into the troposphere. NASA research has shown that storms with cloud tops that cold have the ability to generate heavy rain.Tropical Storm Omais forms in the Northwestern Pacific

At 11 a.m. EDT (3 p.m. UTC) on Aug. 4, Tropical Storm Omais had maximum sustained winds near 46 mph (40 knots/74 kph). The storm developed quickly from a low pressure area into a tropical storm. Omais was centered near 19.3 degrees north latitude and 146.2 degrees east longitude, about 223 nautical miles north of Saipan, Northern Marianas Islands, and farther away from Guam. Omais has tracked north-northwestward at 3.4 mph (3 knots/5.5 kph) and is expected to continue in that general direction.

NOAA's National Weather Service Office in Guam has not issued any watches or warnings associated with Omais as the storm is far to the north.

The Joint Typhoon Warning Center forecast calls for Omais to move on a northerly track and strengthen to a typhoon by Aug. 6 after passing far to the east of the island of Iwo To, Japan. It is then expected to continue tracking in a northerly direction through the northwestern Pacific Ocean.

<div class="img-wrapper">Tropical storm Earl has been intensifying as it moves through the Caribbean Sea. The GPM satellite spotted hot towers, towering thunderstorms within Earl that indicate the storm may intensify.</div>
The National Hurricane Center (NHC) now predicts that Earl will be a hurricane before it hits Mexico's Yucatan Peninsula tomorrow afternoon. Earl is predicted by NHC to remain in a light to moderate vertical wind shear environment over very warm sea surface temperatures until landfall.

The Global Precipitation Measurement mission or <a href="http://www.earth.com/product/low-flow-faucet-aerator-1-0-gpm-2-pack/">GPM</a> core observatory satellite passed over intensifying tropical storm Earl in the Caribbean Sea northeast of Honduras on Aug. 2, 2016 at 11:56 p.m. EDT (Aug. 3, 2016 at 0356 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed that powerful storms around Earl's forming eye were dropping extremely heavy rainfall. DPR found that rain was falling at a rate of over 251 mm (9.8 inches) per hour in a band of powerful convective storms.

GPM's Radar (DPR Ku band) were used to show in 3-D the towering thunderstorms near Earl's center reaching heights of over 16 km (9.9 miles). These strong thunderstorms called "hot towers" often lead to rapid intensification in a tropical cyclone. NASA research has shown that whenever there is the presence of hot towers, the storm usually intensifies within six hours. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency.

On Aug. 3, 2016 a hurricane warning is in effect for Puerto Costa Maya, Mexico, southward to the Belize/Guatemala border and for the Bay Islands, Honduras. A tropical storm warning is in effect for the north coast of Honduras from Cabo Gracias a Dios westward to the Honduras/Guatemala border and north of Puerto Costa Maya to Punta Allen, Mexico.

The heavy rainfall rates seen by GPM are evident in the forecast from the National Hurricane Center (NHC). The NHC forecast noted that Earl is expected to produce total rain accumulations of 8 to 12 inches over portions of Belize, Honduras, Guatemala, and the Yucatan peninsula of Mexico through Thursday night. Very heavy rain will reach the Mexican states of Tabasco and Veracruz between Thursday night and Saturday morning. Isolated maximum amounts of 16 inches are possible in Belize and Mexico.

At 2 p.m. EDT (1800 UTC), the center of Tropical Storm Earl was located near latitude 16.8 North, longitude 85.6 West. Earl is moving toward the west near 14 mph (22 kph), and this general motion is expected to continue with some decrease in forward speed during the next 48 hours. On the forecast track, the core of Earl is expected to pass near the Honduras Bay Islands this afternoon, and then make landfall in Belize tonight or early Thursday.

Maximum sustained winds remain near 70 mph (110 kph) with higher gusts. Additional strengthening is forecast during the next 12 hours or so, and Earl is expected to be a hurricane by the time it makes landfall along the coast of Belize.

NOAA's GOES-East satellite has been providing visible and infrared data on Hurricane Earl since its development as a tropical depression on Aug. 2. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, the NASA/NOAA GOES project combined the data into an animation that showed the movement and strengthening of Earl from Aug. 2 to Aug. 4 through the Caribbean Sea.Satellite animation shows landfall of Hurricane Earl in Belize

At 1 a.m. EDT on Thursday, Aug. 4, 2016 reports from an<a href="http://www.earth.com/news/us-air-force-ignored-climate-change-warnings-at-space-fence-radar-site/"> Air Force</a> Reserve Hurricane Hunter aircraft indicated Earl's maximum sustained winds increased to near 80 mph (130 kph) making it a hurricane. At 2 a.m. EDT Hurricane Earl made landfall 5 miles southwest of Belize City, Belize.

By 11 a.m. EDT on Aug. 4, Earl was inland and already 115 miles (185 km) west of Belize City and had weakened to a tropical storm. The Government of Belize has discontinued all coastal warnings. There are no coastal watches or warnings in effect. Interests along the southern Bay of Campeche should monitor the progress of Earl.

The center of Tropical Storm Earl was located well inland near 17.2 degrees north latitude and 89.9 degrees west longitude. Earl was moving toward the west near 12 mph (19 kph), and the National Hurricane Center (NHC) said this general motion is expected to continue during the next couple of days. On the forecast track, NHC said Earl will continue to move across northern Guatemala and southeastern Mexico tonight and Friday. The estimated minimum central pressure is 990 millibars.

Maximum sustained winds have decreased to near 50 mph (85 kph) with higher gusts. Additional weakening is expected as the center moves over high terrain, and Earl is forecast to weaken to a tropical depression by tonight.

In the NHC discussion, Forecaster Lixion Avila wrote: "Earl is already well inland over northern Guatemala, and although visible satellite images still show a vigorous circulation, the convection is rapidly decreasing. There are no wind observations near the center, but the best estimate of the initial intensity is 45 knots. Since most of the circulation of Earl is forecast to move over the high terrain of Guatemala and southeastern Mexico, rapid weakening is anticipated. Earl is expected to degenerate into a tropical depression tonight and into a remnant low in a day or so."

<div>Adaptation to climate risks: Political affiliation matters. A new study reveals that those who affiliate with the Democratic Party have different views than those who vote Republican on the following climate risks: the likelihood of floods occurring, adopting protection measures, and expectations of disaster relief from the government. The study was jointly conducted by VU University in <a href="http://www.earth.com/video/earth-space-amsterdam/">Amsterdam</a>, Utrecht University School of Economics in The <a href="https://www.bing.com/search?q=netherlands&amp;form=EDGEAR&amp;qs=PF&amp;cvid=7205a2e0d6b340a2a21adb4dd802cd50&amp;cc=US&amp;setlang=en-US&amp;elv=AY3%21uAY7tbNNZGZ2yiGNjfNhatJdGhLPZsFzwUkaW6Fhj0dto0zm5*YtANFgMvQHScN2kDjckN7P0h7k*xOQw3kfGg2y%21Zv0fxBmUUqF6ItY&amp;plvar=0&amp;PC=HCTS">Netherlands</a>, and the Center for Risk Management and Decision Processes at the Wharton School of the University of Pennsylvania in Philadelphia, USA.</div>
<div>

The study, published today in Springer's journal <em>Climatic Change</em>, focused on the flood risk in New York City. Data was collected through a telephonic survey conducted six months after Superstorm Sandy. It included a random sample of 1,035 homeowners with ground level property in flood-prone areas of New York City. Respondents' political affiliation was determined by what political party they voted for in the November 2012 presidential election. Adaptation to climate risks: Political affiliation matters

<strong>Key findings:</strong>
<ul>
 	<li>Democrats' perception of their probability of experiencing flood damage is significantly higher than Republicans'. They are also more likely to expect climate change to increase the flood risk they face in the future.</li>
 	<li>Democrats are also more likely to invest in individual flood protection measures.</li>
 	<li>Less than half of Democrats and a third of Republicans trust the government to address the flood risk posed in their area of residence.</li>
 	<li>50% more Democrats than Republicans in the study expect to receive federal disaster relief after a major flood.</li>
 	<li>Interestingly, given the above, the researchers find no difference in flood insurance adoption.</li>
</ul>
"We knew Republicans and Democrats in the United States often perceive the risk of climate change differently. We now know they prepare for climate disasters differently, too. This finding has important implications," report Wouter Botzen and Erwann Michel-Kerjan, who co-led the study.

The authors suggest that flood risk awareness campaigns and policies be aimed at encouraging people to adopt preparedness and risk reduction measures and to purchase adequate insurance coverage, irrespective of their political ideology. The strengthening of building codes in NYC after Superstorm Sandy is a good example of how cities can limit damage from future floods, become more resilient, and limit the need for government disaster relief.

<div class="img-wrapper">Melting Greenland ice sheet could release frozen Cold War-era waste. Camp Century, a U.S. military base built within the Greenland Ice Sheet in 1959, doubled as a top-secret site for testing the feasibility of deploying nuclear missiles from the Arctic during the Cold War. When the camp was decommissioned in 1967, its infrastructure and waste were abandoned under the assumption they would be entombed forever by perpetual snowfall.</div>
But climate change has warmed the Arctic more than any other region on Earth, and a new study finds the portion of the ice sheet covering Camp Century could start to melt by the end of the century. If the ice melts, the camp's infrastructure, as well as any remaining biological, chemical and radioactive waste, could re-enter the environment and potentially disrupt nearby ecosystems, according to the study's authors. Melting Greenland ice sheet could release frozen Cold War-era waste

Determining who is responsible for cleaning up the waste could also lead to political disputes not considered before, according to the study's authors.

"Two generations ago, people were interring waste in different areas of the world, and now climate change is modifying those sites," said William Colgan, a climate and glacier scientist at York University in Toronto, Canada, and lead author of the new study. "It's a new breed of political challenge we have to think about."

The new study was published today in <em>Geophysical Research Letters</em>, a journal of the American Geophysical Union.

The assumption that any waste could be buried forever under ice is unrealistic, according to James White, a climate scientist at the University of Colorado in Boulder, who was not connected to the study.

"The question is whether it's going to come out in hundreds of years, in thousands of years, or in tens of thousands of years," White said. "This stuff was going to come out anyway, but what climate change did was press the gas pedal to the floor and say, 'it's going to come out a lot faster than you thought.'"

During the <a href="http://www.earth.com/news/cold-war-spy-images-himalayan-melt/">Cold War</a>, U.S. military attention shifted to the Arctic -- the shortest route between the U.S. and the former Soviet Union. In April 1951, the U.S. and Denmark agreed to defend Greenland, a Danish territory, from Soviet attack, and the U.S. built several air bases in Greenland that year.

In 1959, the <a href="https://en.wikipedia.org/wiki/NASA">U.S</a>. Army Corps of Engineers built Camp Century 200 kilometers (125 miles) inland from the Greenland coast. Encased completely within the ice sheet, Camp Century became known as the "city under the ice."

The camp's official purpose was to test construction techniques in the Arctic and conduct scientific research. While in operation, the camp housed 85 to 200 soldiers and was powered by a nuclear reactor. Scientists at Camp Century took ice core samples providing climate data still cited in research today, Colgan said.

The camp also provided proof of concept for a top secret program to test the feasibility of building nuclear missile launch sites close enough to reach the Soviet Union. While never built, a larger planned camp based on the concept of Camp Century would have housed a 4,000-kilometer (2,500-mile) long tunnel system underneath the ice, capable of deploying up to 600 nuclear missiles.

Although the camp was built with Denmark's approval, the missile launch program, known as Project Iceworm, was kept secret from the Danish government. Several years after the camp became operational, Project Iceworm was rejected by the Joint Chiefs of Staff and the camp was decommissioned. The Army Corps of Engineers removed the nuclear reaction chamber but left the camp's infrastructure and all other waste behind, assuming the ice sheet would secure them forever. In the decades since, falling snow has buried the camp roughly 35 meters (115 feet) further underneath the ice.

In the new study, Colgan and his team took an inventory of the wastes at Camp Century and ran climate model simulations to determine whether the waste will stay put in a warming Arctic. The team analyzed historical U.S. army engineering documents to determine where and how deep the wastes were buried and how much the ice cap had moved since the 1950s.

"Looking at the data, we can see right where it's buried," says Mike MacFerrin, a CIRES researcher who is co-author on the paper. MacFerrin analyzed ground-penetrating radar from NASA's Operation IceBridge aircraft to pinpoint the camp's current location and depth. "The radar shows smooth layers of snow and ice until reaching the camp. Then the signal gets messy. We don't yet have enough detail to map exactly what all is down there, but the outline is clear."

The team found the waste at Camp Century covers 55 hectares (136 acres), roughly the size of 100 football fields. They estimate the site contains 200,000 liters (53,000 gallons) of diesel fuel, enough for a car to circle the globe 80 times. Based on building materials used in the Arctic at the time, the authors speculate the site contains polychlorinated biphenyls (PCBs), pollutants toxic to human health. They also estimate the site has 240,000 liters (63,000 gallons) of waste water, including sewage, along with an unknown amount of radioactive coolant from the nuclear generator.

Looking at existing business-as-usual climate projections, the team determined the wastes would not remain encased in ice forever, as was assumed by both the U.S. and Denmark when the camp was abandoned. Instead, they could melt and re-enter the environment.

"When we looked at the climate simulations, they suggested that rather than perpetual snowfall, it seems that as early as 2090, the site could transition from net snowfall to net melt," Colgan said. "Once the site transitions from net snowfall to net melt, it's only a matter of time before the wastes melt out; it becomes irreversible."

Camp Century's waste presents a significant environmental hazard, according to the study's authors. When the ice melts, pollutants could be transported to the ocean, where they could disrupt marine ecosystems, Colgan said.

Based on ice sheet observations near Camp Century but at lower elevations, the camp's waste could be exposed sooner than the study's models predict, said Jennifer Mercer, a cryospheric scientist with the National Science Foundation who specializes in operations on the Greenland Ice Sheet and who was not connected to the study.

The study does not advocate for starting remediation activities at Camp Century now. The waste is buried tens of meters below the ice, and any cleanup activities would be costly and technically challenging, Colgan said.

"It really becomes a situation of waiting until the ice sheet has melted down to almost expose the wastes that anyone should advocate for site remediation," he said.

But the new study does raise questions about who is responsible for cleaning up the waste when it is exposed. International law is clear about responsibility for preventing future hazardous waste, but ambiguous about who is liable for waste already discarded, said Jessica Green, a political scientist specializing in international environmental law at New York University who was not connected to the study. Although Camp Century was a U.S. base, it is on Danish soil, and although Greenland is a Danish territory, it is now self-governing, she said.

The implications of climate change on politically ambiguous abandoned wastes have not been considered before, according to the study's authors.

"The study identifies a big hole in the extant set of laws and rules we have to deal with environmental problems globally," Green said.

<h2 class="wp-block-heading" id="h-ai-training-transforms-workplace-fear-factor-into-competitive-advantage">AI training transforms workplace 'fear factor' into competitive advantage</h2>



<p>Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.</p>



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



<p>A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.</p>



<p>Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.</p>



<p>Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents".  In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively.   MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.</p>



<p>MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization.  The training provided by MindStudio is applicable across other AI Agent building platforms as well.</p>



<p>Revolutionary productivity through focused learning</p>



<p>Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.</p>



<p>Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.</p>



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



<p>The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.</p>



<p>A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.</p>



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



<p>Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.</p>



<p>This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.</p>

<p>The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.</p>



<p>PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.</p>



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



<p>AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.</p>



<p>In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.</p>



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>



<p>The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.</p>



<p>As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.</p>



<p>The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.</p>

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



<p>The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.</p>



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



<p>Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.</p>



<p>The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.</p>



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



<p>The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.</p>



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



<p>While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.</p>



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



<p>As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.</p>



<p>The study is published in the journal&nbsp;<a href="http://dx.doi.org/10.1038/s41467-023-44335-3" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a>.</p>

<h2 class="wp-block-heading" id="h-other-people-s-reactions-influence-children-s-eating-habits">Other people's reactions influence children's eating habits</h2>



<p>Many children are finicky eaters, but research explains how <a href="https://www.earth.com/news/scientists-have-learned-why-so-many-kids-dislike-vegetables/" target="_blank" rel="noreferrer noopener">watching others eat and social modeling</a> influence the eating habits of children.</p>



<h2 class="wp-block-heading">Study Methodology Demonstrates Social Learning Impact</h2>



<p>Researchers at <a href="https://www.aston.ac.uk/hls/school-of-psychology" target="_blank" rel="noreferrer noopener">Aston University School of Psychology</a> have published findings in Frontiers in Psychology that illuminate the neurobiological foundations of food preference development through observational learning. The investigation employed controlled video stimuli featuring adults consuming raw broccoli while displaying systematically varied facial expressions to measure participant responses.</p>



<h2 class="wp-block-heading">Asymmetrical Response Patterns Identified</h2>



<p>The research, conducted with 204 female participants, revealed a pronounced asymmetry in social modeling effects. Negative facial expressions during vegetable consumption significantly diminished observer food preference ratings, while positive expressions failed to produce corresponding increases in vegetable appeal. This finding challenges conventional assumptions about the bidirectional nature of social influence in dietary behavior formation.</p>



<h2 class="wp-block-heading">Evolutionary Psychology Framework Applied</h2>



<p>Dr. Katie Edwards and her research team propose that these results reflect adaptive mechanisms developed through evolutionary processes. The heightened sensitivity to disgust expressions likely functions as a protective system, enabling individuals to identify potentially harmful foods through social cues without direct risk exposure.</p>



<h2 class="wp-block-heading">Clinical and Educational Implications</h2>



<p>These findings carry substantial implications for pediatric nutrition interventions and family meal dynamics. The research suggests that parental expressions of distaste during vegetable consumption may inadvertently reinforce children's existing food aversions through unconscious social transmission pathways.</p>



<h2 class="wp-block-heading">Future Research Directions</h2>



<p>The study establishes a foundation for expanded investigation into real-time social modeling effects and cross-demographic applicability. Researchers emphasize the necessity for longitudinal studies examining actual consumption behaviors rather than preference ratings alone, particularly within family contexts where social learning occurs most frequently.</p>

<h2 class="wp-block-heading" id="h-cancer-causing-protein-bound-and-blocked">Cancer-causing protein bound and blocked</h2>



<p>In a discovery that can one day revolutionize cancer treatment, researchers at the <a href="https://www.ucr.edu/" target="_blank" rel="noreferrer noopener">University of California, Riverside</a> have successfully developed a means of controlling MYC, a notoriously slippery protein that causes approximately <a href="https://www.earth.com/news/chaotic-protein-that-fuels-75-of-cancers-can-be-controlled/" target="_blank" rel="noreferrer noopener">75% of all cancers in humans</a>.</p>



<h2 class="wp-block-heading" id="h-what-makes-myc-different">What makes MYC different</h2>



<p>MYC presents a unique challenge when studying cancer. Normally, this protein plays a vital role in healthy cells. It carefully controls transcription - the process that converts genetic information from DNA and RNA into proteins.</p>



<p>However, cancer changes everything. In cancer cells, MYC becomes a destructive force. It operates in overdrive mode with no regulation whatsoever.</p>



<p>Professor Min Xue, who led the research team, explains it simply: "MYC is less like food for cancer cells and more like a steroid. It drives cancer's aggressive growth." This superactive behavior makes MYC involved in three out of every four cancer cases.</p>



<h2 class="wp-block-heading" id="h-why-myc-is-hard-to-target">Why MYC is hard to target</h2>



<p>Despite its clear role in cancer, targeting MYC has been one of medicine's biggest challenges. The main problem lies in MYC's unusual structure - or rather, its complete lack of structure.</p>



<p>Professor Xue describes the protein as "basically a glob of randomness." This means conventional drug discovery methods don't work. These traditional approaches rely on sharply defined protein structures. MYC simply doesn't have one.</p>



<h2 class="wp-block-heading">A New Approach to Fighting MYC</h2>



<p>The UCR research team developed a clever solution. They designed a special peptide molecule that could selectively bind to MYC. More importantly, this peptide could block MYC's destructive activity.</p>



<p>The key was fine-tuning two specific features: the peptide's stiffness and its shape. Through careful adjustments, researchers achieved something remarkable. They reached "sub-micro-molar affinity" - meaning their peptide binds as strongly as antibodies do.</p>



<h2 class="wp-block-heading" id="h-breakthrough-results">Breakthrough results</h2>



<p>This accomplishment represents a major leap beyond previous attempts. The researchers enhanced their peptide's binding strength by two orders of magnitude. This dramatic improvement brings the work significantly closer to practical drug development goals.</p>



<p>The research opens new possibilities for treating the vast majority of cancers where MYC plays a destructive role.</p>



<p>The researchers are presently optimizing peptide-delivery systems based on lipid nanoparticles that deliver the peptide effectively into cancer cells. The<a href="https://www.nih.gov/" target="_blank" rel="noreferrer noopener"> National Institutes of Health</a> and the <a href="https://www.defense.gov/" target="_blank" rel="noreferrer noopener">U.S. Department of Defense</a> funded the study, which appeared in the Journal of the <a href="https://www.acs.org/" target="_blank" rel="noreferrer noopener">American Chemical Society</a>.<br>This research offers renewed hope against cancer, and it can potentially open a door to more effective cancer therapies for most cancer patients worldwide.</p>

<p>On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.</p>



<p>This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.</p>



<p>Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.</p>



<p>The find upsets the traditional timeline of sea predators.  Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas.  These worms were building sophisticated food webs several million years before other predator groups arose.</p>



<p>Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.</p>

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



<p>Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.</p>



<p>Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.</p>



<h2 class="wp-block-heading" id="h-the-cairo-forest-discovery">The Cairo forest discovery</h2>



<p>385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.</p>



<p>The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.</p>



<p>Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.</p>



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



<p>The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."</p>



<p>This discovery pushes back advanced tree evolution by millions of years. The research, published in <em><a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a></em> in December 2019, fundamentally changes our understanding of when complex forests first emerged.</p>



<p>Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.</p>



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet <em>Archaeopteris</em>: the first modern tree</h2>



<p>The star of this ancient forest is <em>Archaeopteris</em> – not to be confused with the feathered dinosaur <em>Archaeopteryx</em>. This tree was far older and more revolutionary.</p>



<p>William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.</p>



<p>Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.</p>



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



<p>These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.</p>



<p>This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.</p>



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



<p>The forest was remarkably diverse. Scientists identified <em>Eospermatopteris</em>, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.</p>



<p>All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.</p>



<h2 class="wp-block-heading" id="h-scientific-significance">Scientific significance</h2>



<p>Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.</p>



<p>Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."</p>



<p>The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.</p>



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



<p>In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.</p>



<p>Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.</p>



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



<p>Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.</p>



<p>Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.</p>



<p>These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.</p>



<p>The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.</p>



<p>The full study was published in the journal <em>Current Biology</em>.</p>

</div><figcaption class="wp-element-caption">Our bodies hits two 'aging cliffs' at these ages.</figcaption></figure>



<h2 class="wp-block-heading" id="h-scientists-map-exact-ages-when-your-body-rapidly-ages">Scientists Map Exact Ages When Your Body Rapidly Ages</h2>



<p>Scientists have <a href="https://www.earth.com/news/human-bodies-begin-breaking-down-two-very-precise-ages/#google_vignette">discovered that aging</a> isn't the gradual, steady process many assume it to be. Instead, researchers from Stanford Medicine have found that our bodies undergo dramatic molecular changes at two specific ages: 44 and 60. This research, published in Nature Aging, reveals that aging happens in sudden bursts rather than smooth transitions.</p>



<h2 class="wp-block-heading" id="h-two-waves-of-rapid-aging">Two waves of rapid aging</h2>



<p>The Stanford study tracked over 135,000 different molecules and microbes in 108 participants aged 25 to 75 over several years. Results showed that 81% of all molecules studied exhibited non-linear changes, meaning they shifted dramatically at certain ages rather than changing gradually over time.</p>



<p>Michael Snyder, chair of genetics at Stanford School of Medicine and the study's senior author, noted significant findings. "We're not just changing gradually over time; there are some really dramatic changes. It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that's true no matter what class of molecules you look at."</p>



<p>The first wave of changes occurs around age 44, affecting molecules related to alcohol metabolism, caffeine processing, lipid <a href="https://www.earth.com/news/age-related-changes-in-metabolism-dont-match-our-expectations/" target="_blank" rel="noreferrer noopener">metabolism</a>, <a href="https://www.earth.com/news/heart-disease-remains-the-leading-cause-of-death-worldwide/" target="_blank" rel="noreferrer noopener">cardiovascular disease</a>, and skin and muscle function. The second wave hits around age 60, involving changes in carbohydrate metabolism, immune regulation, kidney function, and again cardiovascular and muscle health.</p>



<h2 class="wp-block-heading" id="h-what-happens-during-these-aging-bursts">What happens during these aging bursts</h2>



<p>During the mid-40s transformation, researchers observed significant changes in how the body processes alcohol and fats. This period often coincides with increased stress levels in many people's lives, potentially contributing to lifestyle factors that accelerate these molecular shifts.</p>



<p>"It's possible some of these changes could be tied to lifestyle or behavioral factors that cluster at these age groups, rather than being driven by biological factors," Snyder explained. For instance, alcohol metabolism dysfunction might result from increased consumption during the typically stressful mid-40s period.</p>



<p>The changes at age 60 are perhaps less surprising, as this is when many age-related diseases begin to manifest more prominently. The molecular shifts affect immune function and kidney health, both critical for maintaining overall wellness as we enter our senior years.</p>



<h2 class="wp-block-heading" id="h-latest-research-confirms-aging-patterns">Latest research confirms aging patterns</h2>



<p>Recent 2025 studies have validated these findings. Research examining tissue samples from 76 people found similar aging patterns, noting an "inflection point" between ages 45 and 55.</p>



<p>Scientists discovered that blood vessels, particularly the aorta, age fastest among all body tissues. This vascular aging may drive aging in other body parts, highlighting cardiovascular health's central role in the aging process.</p>



<h2 class="wp-block-heading" id="h-cellular-changes-and-microbiome-shifts">Cellular changes and microbiome shifts</h2>



<p>The Stanford research revealed that these aging bursts affect our microbiome – the trillions of bacteria, viruses, and fungi living in and on our bodies. These microbial communities undergo substantial shifts during both aging periods, potentially affecting everything from digestion to immune function.</p>



<p>Additionally, researchers found that protein production and gene expression begin to fall out of sync as we age. This breakdown in cellular communication becomes especially pronounced during the two aging waves, contributing to the accumulation of damaged proteins associated with diseases such as <a href="https://www.earth.com/news/alzheimers-may-not-be-brain-disorder-important-data-was-fabricated/" target="_blank" rel="noreferrer noopener">Alzheimer's</a>.</p>



<h2 class="wp-block-heading" id="h-health-implications-and-longevity-considerations">Health implications and longevity considerations</h2>



<p>Understanding these aging patterns has important implications for healthcare strategies. Research suggests that people should pay particular attention to their health during their 40s and 60s, when these dramatic molecular changes occur.</p>



<p>Snyder emphasized the importance of proactive health measures. "I'm a big believer that we should try to adjust our lifestyles while we're still healthy," he noted. This might include increasing exercise to protect heart health and maintain muscle mass, or reducing alcohol consumption in the 40s as the body's ability to metabolize it declines.</p>



<h2 class="wp-block-heading" id="h-new-approaches-to-anti-aging-treatment">New approaches to anti-aging treatment</h2>



<p>Aging research has seen notable advances in 2025. Harvard Medical School scientists developed chemical cocktails that reverse cellular aging without genetic modification. These six combinations restored aged cells to youthfulness in under a week, offering safer alternatives to gene therapy.</p>



<p>Researchers identified new biomarkers like "InflammAge," a saliva-based test measuring chronic inflammation associated with aging. This non-invasive approach could change how we monitor aging and intervention.</p>



<h2 class="wp-block-heading" id="h-future-directions-in-aging-research">Future directions in aging research</h2>



<p>Emerging technologies including artificial intelligence, cellular reprogramming, and senolytic therapies, are opening new possibilities for extending healthspan. Companies develop treatments targeting aging's fundamental mechanisms rather than just managing age-related diseases.</p>



<p>The Stanford findings provide a roadmap for implementing preventive measures. Rather than waiting for symptoms, people can prepare for and potentially mitigate these predictable aging waves.</p>



<p>As aging understanding evolves, one thing becomes clear: aging isn't inevitable decline, but specific biological events we may learn to prevent or reverse. The key is recognizing when these transitions occur and taking proactive health steps during vulnerable periods.</p>

Scientists discover we age in bursts

<h2 class="wp-block-heading" id="h-scientists-discover-the-brain-s-tickling-command-center">Scientists discover the brain's 'tickling command center'</h2>



<p>Researchers have finally solved one of humanity's most enduring mysteries: why we can't <a href="https://www.earth.com/news/after-centuries-of-debate-we-still-dont-know-how-tickling-works/" target="_blank" rel="noreferrer noopener">tickle</a> ourselves and what makes some people incredibly ticklish while others barely react? Recent scientific discoveries are revolutionizing our understanding of this peculiar human behavior.</p>



<h2 class="wp-block-heading" id="h-breakthrough-discovery-in-the-brain">Breakthrough discovery in the brain</h2>



<p>In 2023, Dr. Michael Brecht's team at <a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Humboldt University</a>-<a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Berlin</a> made a major discovery published in the <a href="https://www.cell.com/iscience/fulltext/S2589-0042(22)01991-5" target="_blank" rel="noreferrer noopener">journal <em>Neuron</em></a>. They identified the brain's actual "tickling command center" – specific neurons in a region called the periaqueductal gray that control both tickling responses and play behavior.</p>



<p>When researchers used cutting-edge optogenetic technology to shut down these neurons in laboratory rats, something remarkable happened. The animals completely lost their ability to be tickled or engage in playful behavior.</p>



<p>"We found that global blockade of the rat periaqueductal gray with either muscimol or lidocaine interfered with ticklishness and play," the research team reported in their study.</p>



<h2 class="wp-block-heading" id="h-two-types-of-tickling-revealed">Two types of tickling revealed</h2>



<p>What we call "tickling" is two completely different phenomena, according to the latest research. Light tickling – that feathery sensation that makes you want to scratch – is essentially your body's sophisticated bug detection system. This alerts you to potential insects or parasites on your skin.</p>



<p>Deep tickling – the kind that makes you laugh uncontrollably – involves complex brain circuits and is fundamentally social. You literally cannot tickle yourself with this type of stimulation.</p>



<h2 class="wp-block-heading" id="h-why-self-tickling-is-impossible">Why self-tickling is impossible</h2>



<p>Your cerebellum acts like a prediction machine, recent findings show. When you move your own hand to touch yourself, your brain generates precise predictions about what you will feel and then cancels out the tickling sensation through neural inhibition.</p>



<p>When someone else tickles you, your brain can't predict their movements, so the full tickling response activates. It's like your brain's way of distinguishing between self and others.</p>



<h2 class="wp-block-heading" id="h-individual-differences-explained">Individual differences explained</h2>



<p>Individual differences in ticklishness depend on genetics, psychology, and even trust. Dr. Xinzhong Dong at <a href="https://www.jhu.edu/" target="_blank" rel="noreferrer noopener">Johns Hopkins University</a> notes that people with denser nerve endings tend to be more sensitive.</p>



<p>Psychological factors matter just as much. You respond more strongly when tickled by people you trust, and anxiety completely shuts down tickling responses. This explains why the same physical stimulus can produce completely different reactions depending on who's doing the tickling.</p>



<h2 class="wp-block-heading" id="h-controlling-your-ticklishness">Controlling your ticklishness</h2>



<p>Science offers answers for controlling your ticklishness. You can reduce tickling sensitivity through systematic desensitization – gradual exposure in controlled settings.</p>



<p>Dr. Konstantina Kilteni's 2025 research, published in <em><a href="https://www.science.org/doi/10.1126/sciadv.adt0350" target="_blank" rel="noreferrer noopener">Science Advances</a></em>, reveals another technique: place your hand on the tickler's hand. This allows your brain to partially predict the sensations, reducing the tickling response by up to 90 percent.</p>



<p>"Your brain is essentially learning to override its own reflexes," Kilteni explained in her review of tickling research.</p>



<h2 class="wp-block-heading" id="h-evolutionary-purpose-discovered">Evolutionary purpose discovered</h2>



<p>From an evolutionary perspective, tickling serves vital functions according to <a href="https://www.umd.edu" target="_blank" rel="noreferrer noopener">University of Maryland</a> researcher Dr. Robert Provine's extensive studies. It trains our defense reflexes for vulnerable body areas and facilitates social bonding between family members.</p>



<p>Tickling-induced laughter is actually one of the first forms of communication between infants and caregivers. "Tickle involves a neurological self/nonself discrimination, providing the most primitive social scenario," Provine noted in his research.</p>



<h2 class="wp-block-heading" id="h-clinical-applications-emerge">Clinical applications emerge</h2>



<p>Research shows people with autism spectrum disorder perceive touches as more ticklish than people without the condition. Investigating this difference could provide insight into brain differences and help advance autism research.</p>



<p>People with schizophrenia tend to experience self-touches similarly to external tickles, allowing them to essentially tickle themselves. This suggests altered sensory prediction mechanisms in the condition.</p>



<h2 class="wp-block-heading" id="h-animal-research-reveals-universal-nature">Animal research reveals universal nature</h2>



<p>Scientists have discovered that many species beyond humans are ticklish. Rats emit ultrasonic "laughs" when tickled, while chimpanzees, gorillas, and orangutans all respond to tickling stimulation.</p>



<p>This widespread occurrence across species suggests that tickling serves fundamental biological and social functions that evolved long before humans developed complex language and culture.</p>



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



<p>Dr. Kilteni argues that tickling research deserves more scientific attention. "It is a complex interplay of motor, social, neurological, developmental, and evolutionary aspects," she stated in her recent review.</p>



<p>New haptic technologies and advanced research methodologies now permit scientists to investigate tickle sensation with unprecedented precision. Standardized experimental methods using mechanical tickling devices ensure consistent results across studies.</p>



<p>Recent findings published in <em>Science Advances</em> show that tickling research is opening new doors in neuroscience, potentially leading to a better understanding of social behavior, sensory processing, and neurological conditions.</p>

</div><figcaption class="wp-element-caption">Dr. Ronald Mallett from the University of Connecticut reveals secret mission to create working time travel device.</figcaption></figure>



<h2 class="wp-block-heading" id="h-could-an-equation-truly-bend-time-a-physicist-s-decades-long-quest-to-rewrite-reality">Could an equation truly bend time? A physicist's decades-long quest to rewrite reality</h2>



<p>Imagine the impossible: stepping back through time in a time machine, not in fantasy, but through a scientific endeavor driven by profound personal loss. For <a href="https://www.earth.com/news/astrophysicist-says-hes-cracked-the-equation-for-time-travel/" target="_blank" rel="noreferrer noopener">Dr. Ronald Mallett</a>, a distinguished astrophysicist and professor emeritus at the <a href="https://uconn.edu/">University of Connecticut</a>, this deeply human longing has fueled a lifelong mission. He claims to have discovered the equation that could unlock temporal displacement, pushing boundaries once deemed purely science fiction.</p>



<h2 class="wp-block-heading" id="h-a-profound-grief-that-forged-a-vision">A profound grief that forged a vision</h2>



<p>Mallett's extraordinary pursuit began with devastating tragedy in 1955. At merely 10 years old, he endured his father Boyd's sudden death—a television repairman whose passion for science had ignited a similar spark in his young son. Boyd Mallett, only 33, succumbed to a heart attack, leaving behind a grief-stricken child searching for solace.</p>



<p>That solace came through H.G. Wells' <em>The Time Machine</em>. Within its pages, Mallett found a captivating concept: "Time is only a kind of Space." These words transformed from a literary phrase into a guiding principle, becoming the driving force behind his unwavering commitment to unraveling time's fundamental mysteries.</p>



<h2 class="wp-block-heading" id="h-from-humble-beginnings-to-academic-heights">From humble beginnings to academic heights</h2>



<p>Mallett's journey was far from straightforward. After serving in the Air Force during the Vietnam War era, he utilized the GI Bill for higher education, earning his Ph.D. in physics from Pennsylvania State University in 1973 at the age of 28.</p>



<p>In 1975, he made history as the first African American professor in the University of Connecticut's physics department, achieving full professorship in 1987 before retiring in 2024 as professor emeritus.</p>



<p>Throughout these successful academic years, Mallett harbored his radical ambition as a closely guarded secret. "I kept my time travel goal a secret," he confessed. "I worried people would think I was nuts." His public research centered on black holes, serving as a "cover story" while he quietly developed his revolutionary time travel theory.</p>



<h2 class="wp-block-heading" id="h-the-breakthrough-moment">The breakthrough moment</h2>



<p>His pivotal insight arrived while hospitalized for a heart condition—a profound irony given his father's heart attack started this journey. The breakthrough was elegantly simple yet revolutionary: "If gravity can bend time, and light can create gravity, then light can bend time."</p>



<p>"It turns out that black holes can create a gravitational field that could lead to the creation of time loops that could allow us to go back in time," he explained.</p>



<h2 class="wp-block-heading" id="h-the-blueprint-for-a-temporal-vortex">The blueprint for a temporal vortex</h2>



<p>Mallett's vision for a functioning time machine replicates spacetime-warping phenomena around black holes. He offers a compelling analogy: "Picture a cup of coffee. Stir it with a spoon, and the coffee swirls. A spinning black hole does the same to spacetime."</p>



<p>In Einstein's general relativity, the universe is a dynamic fabric woven from space and time. Massive objects like black holes warp this fabric—an effect we perceive as gravity. Mallett theorizes that an intense, continuous, circulating beam of light from a ring of powerful lasers could replicate this gravitational torsion, effectively twisting time into a loop.</p>



<p>This "time loop" would theoretically allow information—or perhaps matter—to travel backward in time. He detailed this mathematical concept in his 2006 autobiography, <em>Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality</em>.</p>



<h2 class="wp-block-heading" id="h-published-research-and-recognition">Published research and recognition</h2>



<p>His work, published in respected journals including <em><a href="https://www.sciencedirect.com/journal/physics-letters-a" target="_blank" rel="noreferrer noopener">Physics Letters A</a></em> and <em><a href="https://link.springer.com/journal/10701" target="_blank" rel="noreferrer noopener">Foundations of Physics</a></em>, suggests circulating laser light could generate gravitational fields potent enough to create closed timelike curves, enabling time travel for data.</p>



<p>Mallett's research has gained worldwide media attention, featured on <a href="https://www.thisamericanlife.org/" target="_blank" rel="noreferrer noopener">National Public Radio's <em>This American Life</em></a>, the <a href="https://www.history.com/" target="_blank" rel="noreferrer noopener">History Channel</a>, and <a href="https://www.today.com/" target="_blank" rel="noreferrer noopener">NBC's <em>Today Show</em></a>. The widespread interest reflects both his compelling personal story and rigorous scientific approach.</p>



<h2 class="wp-block-heading" id="h-the-galactic-hurdles-and-persistent-skepticism">The galactic hurdles and persistent skepticism</h2>



<p>While Mallett's equations captivate imagination, the path to reality faces immense obstacles. The energy requirement is staggering—Mallett acknowledges needing "galactic amounts of energy," far beyond current technological capabilities.</p>



<p>There's also a poignant limitation: even if realized, his machine could only send information back to when it was first activated, meaning it couldn't transport him to 1955 to prevent his father's death.</p>



<p>The scientific community remains skeptical. Physicists Ken Olum and Allen Everett argue that Mallett's proposed laser ring would need to be larger than the observable universe to achieve the necessary spacetime distortion. They invoke Stephen Hawking's chronology protection conjecture, suggesting physics may prevent macroscopic time travel.</p>



<p>Astrophysicist Paul Sutter has voiced doubts about Mallett's underlying mathematics, while science writer Brian Clegg finds the concept intriguing enough to warrant experimental investigation.</p>



<h2 class="wp-block-heading" id="h-a-legacy-that-transcends-time">A legacy that transcends time</h2>



<p>Now approaching 80, Dr. Mallett remains steadfast. "I believe my work will show time travel is possible," he asserts. "Future generations will build on it in ways we can't yet imagine."</p>



<p>His equations, though yet to physically bend time, have bent our collective imagination. Ongoing public interest, evidenced by his continued media appearances and Spike Lee's film adaptation of his memoir, underscores his ideas' profound impact.</p>



<p>More than a scientific pursuit, Mallett's story testifies to human resilience, intellectual courage, and hope's enduring power. Whether his theoretical time machine ever materializes, his legacy is immeasurable—inspiring countless individuals to challenge conventional limits and perceive time not as an unyielding barrier, but as a boundless frontier awaiting exploration.</p>

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



<p>Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?</p>



<p>The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.</p>



<h2 class="wp-block-heading"><strong>What was acid rain?</strong></h2>



<p>Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.</p>



<h2 class="wp-block-heading"><strong>The science behind it</strong></h2>



<p>Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.</p>



<p>While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.</p>



<h2 class="wp-block-heading"><strong>The crisis at its peak</strong></h2>



<p>During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.</p>



<h2 class="wp-block-heading"><strong>Environmental devastation</strong></h2>



<p>The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.</p>



<p>By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.</p>



<p>Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.</p>



<h2 class="wp-block-heading"><strong>Economic impact</strong></h2>



<p>Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.</p>



<h2 class="wp-block-heading"><strong>The solution: government action and technology</strong></h2>



<p>Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.</p>



<h2 class="wp-block-heading"><strong>The Clean Air Act of 1990</strong></h2>



<p>The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.</p>



<h2 class="wp-block-heading"><strong>Cap-and-trade success</strong></h2>



<p>Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.</p>



<p>The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.</p>



<h2 class="wp-block-heading"><strong>Technology advances</strong></h2>



<p>Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.</p>



<p>The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.</p>



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today"><strong>Why we don't hear about it today</strong></h2>



<p>Why did acid rain disappear from headlines? Simple: the problem was largely solved.</p>



<h2 class="wp-block-heading"><strong>Success doesn't make news</strong></h2>



<p>There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.</p>



<h2 class="wp-block-heading"><strong>Mission accomplished</strong></h2>



<p>The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.</p>



<h2 class="wp-block-heading" id="h-is-it-really-gone"><strong>Is it really gone?</strong></h2>



<p>The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.</p>



<p>EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.</p>



<h2 class="wp-block-heading"><strong>What this teaches us</strong></h2>



<p>The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.</p>



<p>Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.</p>



<h2 class="wp-block-heading"><strong>Conclusion</strong></h2>



<p>Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.</p>



<p>Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.</p>



<p>This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.</p>



<p>Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.</p>

<h2 class="wp-block-heading"><strong>Frequently Asked Questions</strong></h2>



<p><strong>1. Is acid rain completely gone?</strong> No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.</p>



<p><strong>2. How long did solving take?</strong> Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.</p>



<p><strong>3. What made the solution successful?</strong> Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.</p>



<p><strong>4. Do other countries have acid rain problems?</strong> Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.</p>



<p><strong>5. Could acid rain return?</strong> Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.</p>



<p><strong>6. Can you recommend any teaching tools on the subject of "acid rain"?</strong> The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a></p>

<p>Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. </p>



<p>The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.</p>



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

<p>Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. </p>



<p>Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.</p>



<p>Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. </p>



<p>They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).</p>



<p>Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.</p>



<p>Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.</p>



<p>This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.</p>



<p>The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.</p>



<p>"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.</p>



<p>"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.</p>



<p>"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.</p>



<p>To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;</p>



<p>"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.</p>



<p>"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."</p>



<p>"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;</p>



<p>The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;</p>



<p>Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.</p>



<p>In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;</p>



<p>According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;</p>



<p>Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. </p>



<p>Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.</p>



<p>Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians. </p>

<p>Today’s <strong>Video of the Day</strong> from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.</p>



<p>“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. </p>



<p>The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.</p>



<p>“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;</p>



<p>“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”</p>



<p>The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;</p>



<p>The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?</p>



<p>One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;</p>



<p>While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;</p>

<p>Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.</p>



<p>The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;</p>



<p>"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."</p>



<p>"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."</p>



<p>"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."</p>



<p>The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.</p>
