<p>Acne is annoying. It shows up suddenly, sometimes right before an important event, and refuses to go away quickly. People have tried creams, pills, face washes, and countless home remedies. Some work, some don’t, and many take weeks.</p>



<p>That’s why pimple patches became so popular. You peel one off, stick it on the zit, and hope for the best. But researchers have now created a version that does much more than hide the <a href="https://www.earth.com/news/teen-skin-bacteria-could-hold-the-secret-to-acne-prevention/">problem</a>.</p>



<h2 class="wp-block-heading" id="h-regular-pimple-patches-fall-short">Regular pimple patches fall short</h2>



<p>Regular pimple patches soak up oil and moisture. Some release anti-inflammatory or antibacterial medicine. Others use microarrays - rows of tiny spikes - to push ingredients under the skin. They work, but there’s a catch. </p>



<p>These spikes often shift during use, making the <a href="https://www.earth.com/news/summer-skin-care-dermatologists-reveal-the-ingredients-they-trust/">patch</a> less effective and sometimes irritating. Shayan Fakhraei Lahiji, Yong-Hee Kim, and their colleagues thought they could fix this problem.</p>



<h2 class="wp-block-heading" id="h-a-pimple-patch-that-locks-into-skin">A pimple patch that locks into skin</h2>



<p>The team used a 3D printer to make arrowhead-shaped spikes instead of straight ones. These new shapes grip the skin and stay in place. The base of the patch is made of hyaluronic acid, a common skincare ingredient that also hydrates. </p>



<p>Into that base, the researchers added either antibacterial agents like salicylic acid and cannabis sativa extract or anti-inflammatory agents such as niacinamide and chamomile extract. This design allowed them to treat acne in two stages - kill bacteria first, then calm the <a href="https://www.earth.com/news/indoor-comfort-depends-more-on-your-skin-than-the-air-temperature/">skin</a>.</p>



<p>The patch breaks treatment into steps, similar to how dermatologists manage acne. However, the patch delivers treatment more quickly, precisely, and directly to the affected area without any extra effort.</p>



<h2 class="wp-block-heading" id="h-skin-solutions-for-everyday-people">Skin solutions for everyday people</h2>



<p>To test the system, 20 people with acne tried the patches. On day one, they applied the antibacterial version. For the next six days, they used the anti-inflammatory version. The spikes dissolved in the skin within 30 to 90 minutes without pain or irritation.</p>



<p>Unlike creams or tablets, the patch delivered the medicine right where it was needed. Participants also appreciated the convenience, since the treatment blended easily into daily routines without drawing attention. </p>



<p>This made the patch not only <a href="https://www.earth.com/news/our-skins-bacteria-could-be-a-natural-sunscreen/">effective</a> but also practical for real-world use, a critical factor when developing skincare solutions meant for everyday people rather than just controlled lab settings.</p>



<h2 class="wp-block-heading" id="h-acne-reduced-by-81-percent">Acne reduced by 81 percent</h2>



<p>The numbers were impressive. After three days, acne lesions dropped by 81 percent compared to untreated pimples. </p>



<p>After seven days, the pimples disappeared completely. Sebum levels, the oily substance linked to acne, also went down.</p>



<p>Satisfaction was high - 95 percent of participants said they were happy with the treatment. For people who struggle with breakouts, these results are difficult to ignore.</p>



<h2 class="wp-block-heading" id="h-public-access-to-the-pimple-patch">Public access to the pimple patch</h2>



<p>The team doesn’t plan to keep this as a lab experiment. The patches are expected to hit the market in fall 2025 in South Korea and the United States. </p>



<p>Unlike trendy skincare products that vanish after a year, this one is backed by data. It is simple to use and clinically tested, making it stand out in a crowded industry.</p>



<p>The story doesn’t stop with pimples. Changing the ingredients could turn this small patch into a tool for tackling bigger medical problems.</p>



<p>“Our work highlights the potential of microarray patches as a platform for applications beyond acne treatment, ranging from skin disorders to obesity therapies and vaccine delivery,” explained Yong-Hee Kim.</p>



<h2 class="wp-block-heading" id="h-small-patch-big-future">Small patch, big future</h2>



<p>A simple sticker for acne may not sound groundbreaking. Yet this study shows how science can turn a daily nuisance into an entry point for new medical technology. </p>



<p>Today, it’s about clearer skin. Tomorrow, the same patch design might deliver vaccines or treat chronic diseases. That’s the kind of leap that starts small but matters everywhere.</p>



<p>And while acne may be the starting point, the broader lesson is clear: innovation often grows from solving everyday frustrations. What begins as a fix for a pimple could evolve into a platform that shapes future healthcare, proving that even the smallest inventions can spark big change.</p>



<p>The researchers are part of <a href="https://www.cursusbio.com/" target="_blank" rel="noreferrer noopener">Cursus Bio Inc.</a>, a company that works on microarray technologies.

NASA sees a weaker Hurricane Darby in infrared light. Infrared imagery from NASA's Aqua satellite shows that Hurricane Darby is losing its punch.

When <a href="https://en.wikipedia.org/wiki/NASA">NASA's</a> Aqua satellite passed over Darby on July 18 at 1047 UTC (6:47 a.m. EDT), the Atmospheric Infrared Sounder known as the AIRS instrument looked at the storm in infrared light. Infrared light provides temperature data, which is important in seeing the height and power of the thunderstorms that make up a tropical cyclone. The colder the cloud tops, the higher they are in the atmosphere, and the stronger the convection or uplift of air (and evaporation, condensation and thunderstorm development). NASA sees a weaker Hurricane Darby in infrared light

AIRS data showed that strong convection had been decreasing as cloud top temperatures warmed. That strong convection continued to decrease during the early morning hours on July 19 according to the National Hurricane Center (NHC). However, NHC noted that Darby still has a well-defined and tight circulation.

NHC Forecaster Cangialosi said "Microwave [satellite] data indicates that the low-level center of Darby is located to the south of the eye feature seen in infrared satellite images, which is likely the result of southerly [vertical wind] shear."

At 5 a.m. PDT (0900 UTC) on July 19 the center of Hurricane Darby was located near 19.4 degrees north latitude and 134.4 degrees west longitude. That's about 1,345 miles (2,165 km) east of Hilo, Hawaii. The estimated minimum central pressure is 988 millibars.

Darby is moving toward the west-northwest near 13 mph (20 kph) and this motion is expected to continue today. A turn toward the west is forecast to occur tonight.

Maximum sustained winds remain near 75 mph (120 kph) and weakening is forecast during the next 48 hours. Darby is likely to become a tropical storm later today.

There are no coastal watches or warnings in effect.

Flood damages in Germany could multiply under climate change. Flood-related losses can be expected to increase considerably in Germany as a result of climate change, a new study shows. Extreme events like the severe floods along the river Elbe have already illustrated the potentially devastating consequences of certain weather conditions such as severe rainfall events, when continuing intense rain can no longer be absorbed by the soil and water levels in the rivers rise. Without appropriate adaptation, flood-related damage of currently about 500 million euros a year could multiply in the future, the comprehensive expert analysis published in the journal <em>Natural Hazards and Earth System Sciences</em> highlights. Flood damages in Germany could multiply under climate change

"Extreme events like the Elbe flood in June 2013 may be rare events, but they have major impacts on people and the environment and cause tremendous financial damage," lead author Fred Hattermann from the Potsdam Institute for Climate Impact Research (PIK) explains. The assessment of damage is therefore of importance for local communities but also for the insurance business. Based on an earlier study on behalf of the German Insurance Association (GDV), the researchers reviewed the extent of potential flood damages and reconfirmed their original results by means of a much broader set of climate model combinations and computer simulations. "Not only does our elaborated analyses illustrate once again how flood-related damage will increase in the future, the damages costs could be even higher than previously thought," Hattermann says.

<strong>Rhine, Danube, Elbe, Weser and Ems: 5473 river sections</strong>

"We examined in 35 different projections how the five largest river basins in Germany will be affected by climate change up until the end of this century. 5473 river sections of the Rhine, the Danube, the Elbe, the Weser and the Ems were considered," Hattermann explains. These changes in climate were transformed into changes in flood hazards and their damage potential. "It is remarkable how, despite the uncertainties that come with each scenario analysis, all new scenarios project an increase in damage. So it is all the more important to adapt to a changing climate - and there are quite a lot of possibilities to do so when it comes to floods," says co-author Olaf Burghoff, Head of Statistics (Property) and Natural Hazard Modelling of GDV.

"Research is never finished, but is an ongoing process. As scientists we continuously put our work to the test in order to achieve even more robust results," co-author Peter Hoffmann from PIK says. "Here the recheck turned out to be interesting in more ways than one, because the confirmation of our results also showed that the previous estimates were too conservative." To compute the potential damage, only private houses and small enterprises were considered, but no large firms or power plants which are usually located near rivers. In reality, total economic losses can be essentially higher.

Aqua satellite sees an almost symmetrical Tropical Storm Estelle. <a href="https://www.earth.com/video/nasa-telescope-will-capture-millions-of-galaxies/">NASA's</a> Aqua satellite saw an almost well-rounded Tropical Storm Estelle and identified the locations of the strongest convection in the developing eyewall.

At 10:00 UTC (6 a.m. EDT) today, July 19, NASA's Aqua satellite passed over Tropical Storm Estelle from space and gathered infrared data on the storm. The MODIS instrument, or Moderate Resolution Imaging Spectroradiometer, collected the infrared data that showed a circular storm with two areas of strongest convection (rising air that forms the thunderstorms that make up the storm) where cloud top temperatures were as cold as minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). Those strongest storms were located around the developing eye northeast and southwest of the center. Aqua satellite sees an almost symmetrical Tropical Storm Estelle

Satellite imagery shows that Estelle is strong and almost symmetrical, but periodically dry air has crept into the mid-levels of the tropical storm and prevented further intensification and development of a closed eyewall.

An eyewall is located just outside of the eye and often consists of a vertical wall of clouds. This is the location within a hurricane where the most damaging winds and intense rainfall is found. The eye is a clear area where air sinks and lowest surface pressure can be found. The eye is the point from which the rest of the storm rotates.

At 5 a.m. EDT (0900 UTC) on July 19, 2016 the center of Tropical Storm Estelle was located near 18.5 north latitude and 117.6 west longitude. That's about 585 miles (940 km) west-southwest of the southern tip of Baja California, Mexico.

Estelle was moving toward the west-northwest near 10 mph (17 kph) and the National Hurricane Center (NHC) said that a motion toward the west or west-northwest with some increase in forward speed is expected over the next couple of days. The estimated minimum central pressure is 993 millibars.

Maximum sustained winds are near 65 mph (100 kph) and NHC said some strengthening is possible during the next day or so, and Estelle could still become a hurricane later today. For the latest updates on Estelle, visit the NHC website: <a href="http://www.nhc.noaa.gov/" target="_blank" rel="noopener">http://www.<wbr />nhc.<wbr />noaa.<wbr />gov</a>.

NHC forecaster Stewart said that gradual weakening is expected to begin on Wednesday when Estelle is forecast to move over cooler sea surface temperatures. Those temperatures are cooler than the 26.6 degrees Celsius (80 degrees Fahrenheit) needed to sustain a tropical cyclone. Estelle will also be moving into a drier and more stable air mass which will also sap the tropical cyclone's strength.

How meltwater from the ice sheets disturbed the climate 10,000 years ago. Today, a negative correlation is observed in the amount of rainfall in north-western Africa and north-western Europe. If a humid winter climate prevails in north-western Europe, the climate in north-western Africa is dry. Due to meltwater from melting ice sheets, this correlation was reversed in the early Holocene period; this resulted in both regions being humid respectively dry at the same time. Radical climate change occurred. The researchers have published their report in the current edition of <em>Nature Geoscience</em>.

<strong>Climate determined by opposing atmospheric pressures</strong>

Winter climate in north-western Europe and in the Mediterranean region is controlled by the North Atlantic Oscillation (NAO), i.e. the variation in the difference of atmospheric pressure between the Azores high in the south and the Icelandic low in the north. The researchers aimed to find out how the NAO will respond to melting ice sheets and glaciers around the North Atlantic as they are doing now due to climate change. How meltwater from the ice sheets disturbed the climate 10,000 years ago

<strong>Climate journal from the cave</strong>

To this end, they used speleothems as climate archives: they were able to demonstrate that the ratio of the oxygen isotopes 18O and 16O contained therein is affected by, among other factors, the amount of rainfall. With the aid of speleothems in north-western Morocco and western Germany, they were able to draw conclusions regarding the climate in those regions for the early to late Holocene period from 11,700 to 2,500 years ago.

<strong>Correlation reversed</strong>

The researchers show that on multi-decadal to multi-centennial timescales a negative correlation existed between the amount of rainfall in both regions druing during the mid-Holocene from 8,000 to 5,900 years ago and the late Holocene from 4,700 to 2,500 years ago. That means that one region experienced less rainfall when the other experienced a lot, just like today. In the early Holocene, however, a positive correlation existed between both regions. During the transition from the mid to the late Holocene, the correlation reversed.

<strong>Climate simulations illustrate how climate reacts to the melting of ice</strong>

In order to identify the reasons for this behaviour, the team carried out climate simulations using a coupled atmosphere and ocean model. "A possible explanation for the negative correlation is the melting of the North American ice sheet in the early Holocene period," explains Jasper Wassenburg, who conducted the analyses in collaboration with Prof Dr Adrian Immenhauser at the Department of Sediment and Isotope Geology at the Ruhr-Universität Bochum and is now at the Institute of Geosciences at Johannes Gutenberg University Mainz. During the most recent ice age, this ice sheet covered large areas of Canada. Huge volumes of meltwater flowed into the North Atlantic and changed its circulation pattern. "Using the simulations of our climate model, we demonstrated that the positive correlation of rainfall in Morocco and Germany is caused by a combination of effects: namely the impact of the North American ice shield on the atmospheric circulation and the impact of its meltwater on the oceanic circulation," explains Dr Stephan Dietrich, who evaluated the simulations at the Alfred-Wegener-Institut, Helmholtz-Zentrum für Polar- und Meeresforschung and is now at the Bundesanstalt für Gewässerkunde in Koblenz.

<strong>Ice sheet had a strong cooling effect</strong>

Atmospheric circulation patterns such as the NAO are determined by atmospheric pressure patterns that occur as a result of heating and cooling of air. Oceanic currents play an important role, because they affect the distribution of heat and, thus, <a href="https://www.earth.com/image/simultaneous-atmospheric-rivers-over-australia/">atmospheric</a> circulation. The North American ice sheet has a strong cooling effect: snow and ice reflect most of the solar radiation; researchers refer to this as the albedo-effect. This was the reason why a stable high-pressure field developed above the ice sheet.

Moreover, the meltwater affected the strength of ocean currents, especially the North Atlantic Current. "Even though the precise mechanisms have not yet been fully understood, it is very likely that these effects were essential factors that caused the positive correlation of rainfall in Morocco and Germany to reverse into a negative one, due to the melting of the <a href="https://www.bing.com/search?q=north+american&amp;cvid=af7fe95a9d824005bf1c235d4e5aff5c&amp;FORM=ANAB01&amp;PC=HCTS">North American</a> ice sheet," explains Jasper Wassenburg.

<strong>Similar scenario is conceivable</strong>

If the ice in Greenland melts and the meltwater flows into the North Atlantic, a scenario similar to the one that caused the change of the NAO in the early Holocene period might occur, according the researchers. "However, the climate conditions in the early and late Holocene differed considerably. This is why it is difficult to predict if and how NAO will be affected," conclude the researchers.

"We suggest that it all depends on the speed at which the ice in Greenland will melt and on the volume of meltwater." Detailed reconstructions of the climate and precise measurements of the changes in Greenland ice are necessary in order to understand the mechanisms that contribute to the changes in correlation patterns.

Mercury exposure is common in Northern Canada. Mercury exposure is common in communities in Canada's north, especially in indigenous peoples who consume fish and other wild food with high mercury content, yet current clinical guidelines are not adequate for this population. A review in <em>CMAJ</em> <a href="http://www.cmaj.ca/lookup/doi/10.1503/cmaj.151138" target="_blank" rel="noopener noreferrer"><em>Canadian Medical Association Journal</em></a> provides guidance for health care providers on the effects of mercury exposure and how to manage it in patients who consume diets high in<a href="http://www.earth.com/video/chemists-are-creating-ocean-friendly-fishing-nets/"> fish</a> and marine animals.

"Communities that frequently consume predatory fish and/or marine mammals have elevated mercury exposure," states Dr. Catherine Pirkle, Office of Public Health Studies, University of Hawaii, Manoa, <a href="https://www.bing.com/search?q=honolulu&amp;form=EDGEAR&amp;qs=PF&amp;cvid=6b1fc723263445c59b0badb15d749e9f&amp;cc=US&amp;setlang=en-US&amp;elv=AY3%21uAY7tbNNZGZ2yiGNjfNcI5dP9v9G08gsHOyyYrAtwEMIfrpaBk2M44TSW1qgzjf6K2eW51P6HlAtBtJspf87ytSJni67amRAqgDFA%21MM&amp;plvar=0&amp;PC=HCTS">Honolulu</a>, United States. "It is important for clinicians to be clear on the potential risks, the complexity of the underlying epidemiological data, and how to approach, in a culturally sensitive manner, communities where mercury exposure may be a concern."Mercury exposure is common in Northern Canada

People are usually exposed to mercury through diets of fish and other marine animals. Because the diets of some indigenous people in northern Canada are high in fish and marine mammals, these people are at greater risk of the negative health effects of mercury.

Mercury exposure in pregnant women can have multiple effects in children, affecting brain development. In adults, mercury poisoning can cause vision changes, numbness in extremities, muscle weakness, cognitive changes and even death. Symptoms of mercury poisoning are often difficult to detect and vary between people, requiring diagnosis by a toxicologist or neurologist.

The Nunavik Child Development Study, conducted by Laval University professor Gina Muckle, which for nearly 20 years has been following a cohort of children recruited before birth, found blood mercury concentrations above the Canadian guidance value in 16.9% of school-aged children. In another study of Inuit women aged 18-39 in northern Quebec, 53.3% had blood levels above the guidance value; the average in Canadians is 2.2% (Canadian Health Measures Survey).

Mercury levels vary widely in wild foods and are influenced by location, according to Melanie Lemire, professor with the Department of Social and Preventive Medicine at Université Laval in Quebec. To help health care providers recommend appropriate consumption levels, the authors have included tables with consumption guidelines and blood mercury levels and information on how to test.

The authors caution that there should be a balance between appropriate consumption and overconsumption of wild foods with mercury; if physicians recommend complete avoidance, people may not have enough nutritious food to eat.

"Mercury exposure is one of many health concerns facing northern Canadian communities," write the authors. "Counselling to reduce exposure must recognize and address wider food security issues and nutritional challenges, or it will unlikely be effective."

The rising price -- in both money and health -- of extreme weather events amid rapid urbanisation, and the corresponding value of applying science and technology to reduce the risks, is underscored in six new research papers formally launched at a UN event today.

Assembled by UN University's Malaysia-based International Institute for Global Health (UNU-IIGH), the papers are published in a special issue of the <em>Asia Pacific Journal of Public Health</em>.

And they help inform a special Forum on Advancing Science and Technology in the Implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030, hosted in Kuala Lumpur July 19 by UNU-IIGH and the UN Development Programme.

The papers include a warning about large productivity losses due to heat stress, estimating that in South-East Asia alone "as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs," a figure that may double by 2050 as the planet continues warming.

According to author Tord Kjellstrom of the Health and Environment International Trust, New Zealand: "Current climate conditions in tropical and subtropical parts of the world are already so hot during the hot seasons that occupational health effects occur and work capacity for many people is affected."

Dr. Kjellstrom's paper cites estimated GDP losses due to heat stress for 43 countries: Australia, Bangladesh, Cambodia, China, Costa Rica, Denmark, Democratic Republic of Congo, Ethiopia, Fiji, France, Germany, Ghana, India, Indonesia, Japan, Laos, Malaysia, Maldives, Mexico, Myanmar, Netherlands, New Zealand, Nigeria, Norway, Pakistan, Philippines, Papua New Guinea, Qatar, Russia, Saint Lucia, Samoa, South Africa, South Korea, Spain, Sri Lanka, Sweden, Tanzania, Thailand, Tuvalu, United Kingdom, United States, Vanuatu and Vietnam (see tables at <a href="http://bit.ly/29BL0Dn" target="_blank" rel="noopener noreferrer">http://bit.<wbr />ly/<wbr />29BL0Dn</a>).

The situation in Malaysia is typical of the South-East Asian countries: As work slows or stops to avoid dangerous heat stress, the country's Gross Domestic Product will decline by an estimated 5.9% (value: US $95 billion) by 2030, more than double the estimated 2.8% GDP lost to heat stress in 2010.

According to latest estimates, the global economic cost of reduced productivity may be more than US $2 trillion by 2030. The most susceptible jobs include the lowest paid -- heavy labour and low-skill agricultural and manufacturing.

In 2030, in both India and China, the GDP losses could total $450 billion, although mitigation may be made possible by a major shift in working hours, among other measures employers will need to take to reduce losses.

This problem is already placing major strain on, for example, electricity infrastructure, Dr. Kiellstrom notes. The additional energy needed for a single city the size of Bangkok for each 1°C increase of average ambient temperature can be as much as 2000 MW, roughly the output of a major power plant.

"It is very important to develop and apply adaptation measures now to protect people from the disasters that current climate and slowing changing climate brings," says Dr. Kjellstrom. "However, adaptation is only half an answer -- we must also take decisive action now to mitigate emissions of greenhouse gases. Failure will cause the frequency and intensity of disasters to worsen dramatically beyond 2050, and the situation at the end of this century will be especially alarming for the world's poorest people."

Heat stress is one of several direct and growing impacts on human health due to a warming planet, understanding all of which "is critical in planning for mitigation and adaptation plans," the authors say.

According to the papers:
<ul>
 	<li>Disastrously heavy rains can expand insect breeding sites, drive rodents from their burrows, and contaminate freshwater resources, leading to the spread of disease and compromising safe drinking water supplies.</li>
 	<li>Warmer temperatures often promote the spread of mosquito-borne parasitic and viral diseases by shifting the vectors' geographic range and shortening the pathogen incubation period.</li>
 	<li>Climate change can worsen air quality by triggering fires and dust storms and promoting certain chemical reactions causing respiratory illness and other health problems.</li>
 	<li>In extreme disasters, harm is often amplified by the destruction of medical facilities and disruption of health services</li>
 	<li>Central and south China can anticipate the greatest number of casualties and highest economic losses from extreme weather events in the Asia Pacific region -- the world's most disaster-prone region -- and a more integrated, multidisciplinary approach is needed to upgrade the nation's emergency response system for natural disasters.</li>
 	<li>From 1980 to 2012, roughly 2.1 million people worldwide died as a direct result of nearly 21,000 natural catastrophes such as floods, mudslides, extreme heat, drought, high winds or fires. The cost of those disasters exceeded $4 trillion (US) -- a loss comparable to the current annual GDP of Germany.</li>
 	<li>In Asia Pacific 1.2 billion people have been affected by 1,215 disasters since the millennium. Some 92% of human exposure to floods occurs in Asia Pacific, along with 91% of exposure to cyclones and two-thirds of all exposure to landslides. Between 1970 and 2011, two million people in the region -- 75% of the world total -- were killed by disasters.</li>
 	<li>From 1993 to 2012, the Philippines experienced the highest number of extreme weather events (311), Thailand experienced the greatest financial loss (US$ 5.4 billion) and Myanmar experienced the highest death rate (13.5 deaths per 100,000 people).</li>
 	<li>In just 40 years, from 1970 to 2010, the regional population exposed to flooding risk more than doubled from about 30 million to 64 million while those in cyclone-prone areas rose from roughly 72 to 121 million.</li>
 	<li>Cities cover 2% of world land cover, generate 60 to 80% of greenhouse gas emissions and half of all waste, and are expanding at a rate of 1 million people per week. In a single generation -- from 2000 to 2030 --urban land extents are expected to have tripled.</li>
</ul>
The authors underline that fast-rising numbers of people are being exposed to the impacts of climate change, with much of the increase occurring in cities in flood-prone coastal areas or on hills susceptible to mudslides or landslides. Especially vulnerable are people living in poverty, including about one billion in slums.

Cities -- concentrated sources of energy consumption, heat and pollution, covered in surfaces that absorb warmth -- create local heat islands and impair air quality, both threats to health.

And rising demand for cooling contributes to warming the world. Air conditioners not only pump heat out directly, the electricity required is typically produced by burning fossil fuels, adding to atmospheric greenhouse gases. As well, people acclimatized to air conditioning become less heat tolerant, further increasing demand for cooling.

On the other hand, better urban planning presents "tremendous opportunity" to mitigate the health impacts of more extreme weather events.

Urban planners, the authors say, can help by designing cities "in ways that enhance health, sustainability, and resilience all at once," incorporating better building design, facilitating a shift to renewable energy, and fostering the protection and expansion of tree cover, wetlands and other carbon sinks, for example.

To mitigate the health impacts of longer, more severe extreme weather events, the authors stress the need to replace piecemeal reactive responses with integrated, multi-disciplinary planning approaches.

Beyond better preparation and warning systems to improve disaster response, recommended steps include enhancing drainage to reduce flood risks and strengthening health care, especially in poor areas.

In an introduction to the <a href="http://bit.ly/29Be3Wn" target="_blank" rel="noopener noreferrer">six paper collection</a>, UNU-IIGH Research Fellows Jamal Hisham Hashim and José Siri write that humanity faces "substantial health risks from the degradation of the natural life support systems which are critical for human survival. It has become increasingly apparent that actions to mitigate environmental change have powerful co-benefits for health."

<strong>Comments:</strong>

<em>"It is not clear yet whether considerations of health and sustainability will overrule the press of economic progress in coming decades, and ethical considerations surrounding the right to development are thorny indeed. What is clear is that tremendous opportunities exist to design cities in ways that enhance health, sustainability, and resilience all at once. Decisions made today will have a profound impact on health around the world for many decades to come. We hope these papers help improve understanding of the complex relationship between global environmental change and health, of the threat climate change poses to hard-won advances in human health worldwide, and of policy options available to mitigate these risks."</em>

<strong>Background</strong>

The Sendai Framework for Disaster Risk Reduction 2015-2030 was agreed at the Third UN World Conference on Disaster Risk Reduction in Sendai, Japan in March 2015 and endorsed by the UN General Assembly in June 2015.

The goal of the Sendai Framework is to prevent new and reduce existing disaster risk through the implementation of integrated and inclusive economic, structural, legal, social, health, cultural, educational, environmental, technological, political and institutional measures that prevent and reduce hazard exposure and vulnerability to disaster, increase preparedness for response and recovery, and thus strengthen resilience.

The outcome expected by 2030 is a substantial reduction in disaster risk and losses in lives, livelihoods and health in the economic, physical, social, cultural and environmental aspects of persons, private sector, communities and countries.

A key feature of the Sendai Framework is the shift of focus from managing 'disasters' to managing 'risks'. Such a shift requires a better understanding of risk in all its dimensions of hazards, exposure and vulnerability.

The role of science and technology in providing the evidence and knowledge on risk features heavily in the Sendai Framework.

The UN Office for Disaster Risk Reduction (UNISDR) Science and Technology Conference, held 27-29 January 2016 in Geneva, produced the Science and Technology Roadmap to Support the Implementation of the Sendai Framework.

<hr />

The UNU and UNDP Joint Public Forum and High Level Roundtable on Advancing Science and Technology in the Implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030 has the following goals:
<ul>
 	<li>Raise awareness of the value of science, technology and innovation (STI) for disaster risk reduction</li>
 	<li>Engage key stakeholders in options to build STI capacity in this field, and</li>
 	<li>Identify strategic next steps.</li>

Operation IceBridge targets pools of melt water on Arctic ice. This summer, with sea ice across the Arctic Ocean shrinking to below-average levels, a <a href="https://en.wikipedia.org/wiki/NASA">NASA</a> airborne survey of polar ice just completed its first flights. Its target: aquamarine pools of melt water on the ice surface that may be accelerating the overall sea ice retreat.

NASA's Operation IceBridge completed the first research flight of its new 2016 Arctic summer campaign on July 13. The <a href="http://www.earth.com/video/the-science-behind-big-80s-hair/">science</a> flights, which continue through July 25, are collecting data on sea ice in a year following a record-warm winter in the Arctic. Operation IceBridge targets pools of melt water on Arctic ice

The summer flights will map the extent, frequency and depth of melt ponds, the pools of melt water that form on sea ice during spring and summer. Recent studies have found that the formation of melt ponds early in the summer is a good predictor of the sea ice yearly minimum extent in September: if there are more ponds on the ice earlier in the melt season, they reduce the ability of sea ice to reflect solar radiation, which leads to more melt.

"Although there have been previous airborne campaigns in the Arctic, no one has ever mapped the large-scale depth of melt ponds on sea ice using remote sensing data," said Nathan Kurtz, IceBridge's project scientist and a sea ice researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The information we'll collect is going to show how much water is retained in melt ponds and what kind of topography is needed on the sea ice to constrain them, which will help improve melt pond models."

This short flight campaign is operating from Barrow, Alaska. The flights are low at an altitude of 1500 feet (450 meters) aboard an HU-25C Guardian Falcon aircraft from NASA's Langley Research Center in Hampton, Virginia. The plane carries three instruments that measure changes in the ice elevation and surface temperatures and create color maps of sea ice.

Operation IceBridge provides connectivity between the measurements of polar ice between two NASA satellite campaigns: the Ice, Cloud and land Elevation Satellite, or ICESat, which operated from 2003 to 2009, and its successor, ICESat-2, scheduled to launch by 2018. The Barrow campaign will give a glimpse into what ICESat-2 will be able to observe in the Arctic in the summertime, since the laser altimeter IceBridge carries is similar to the one that will be aboard ICESat-2.

Kurtz expects that flying in the summer will allow his team to find areas of sea ice not covered by snow, which will let them take direct measurements of the freeboard, the fraction of sea ice that floats above the waterline. This measurement would improve studies of sea ice thickness in the Arctic.

Flights will be shorter than the usual IceBridge Arctic flights, due to the Falcon's smaller fuel capacity compared to the P-3 aircraft that IceBridge normally uses in the Arctic. In total, IceBridge scientists are expecting to carry out five 4-hour-long flights, each one covering 1000 nautical miles (1150 miles) and focusing on the Beaufort and Chukchi seas north of Russia, Alaska and Canada..

"The advantage of being based in Barrow is that we'll be starting the flights right from the water's edge," Kurtz said.

For its annual Arctic and Antarctic campaigns, IceBridge flights follow pre-established lines selected by the scientific community. But in Barrow, due to weather uncertainty, the mission will pursue targets of opportunity.

"The day before the flight we'll be looking at weather imagery and models, and I'll try to plan a flight line that basically gets into any hole in the clouds there is, rather than following a specific path," Kurtz said.

NASA's Wallops Flight Facility in Virginia provided the laser altimeter and the infrared camera that are being used during this summer campaign. IceBridge's Digital Mapping System came from NASA's Ames Research Center at Moffett Field, California.

TwoTwo key climate change indicators continue to break records. key climate change indicators -- global surface temperatures and<a href="http://www.earth.com/news/antarctic-ice-loss-sea-level/"> Arctic</a> sea ice extent -- have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data.

Each of the first six months of 2016 set a record as the warmest respective month globally in the modern temperature record, which dates to 1880, according to scientists at <a href="https://en.wikipedia.org/wiki/NASA">NASA's</a> Goddard Institute for Space Studies (GISS) in New York. The six-month period from January to June was also the planet's warmest half-year on record, with an average temperature 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than the late nineteenth century.

Five of the first six months of 2016 also set records for the smallest respective monthly Arctic sea ice extent since consistent satellite records began in 1979, according to analyses developed by scientists at NASA's Goddard Space Flight Center, in Greenbelt, Maryland. The one exception, March, recorded the second smallest extent for that month.

While these two key climate indicators have broken records in 2016, NASA scientists said it is more significant that global temperature and Arctic sea ice are continuing their decades-long trends of change. Both trends are ultimately driven by rising concentrations of heat-trapping carbon dioxide and other greenhouse gases in the atmosphere.

The extent of Arctic sea ice at the peak of the summer melt season now typically covers 40 percent less area than it did in the late 1970s and early 1980s. Arctic sea ice extent in September, the seasonal low point in the annual cycle, has been declining at a rate of 13.4 percent per decade.

"While the El Niño event in the tropical Pacific this winter gave a boost to global temperatures from October onwards, it is the underlying trend which is producing these record numbers," GISS Director Gavin Schmidt said.

Previous El Niño events have driven temperatures to what were then record levels, such as in 1998. But in 2016, even as the effects of the recent El Niño taper off, global temperatures have risen well beyond those of 18 years ago because of the overall warming that has taken place in that time.

The global trend in rising temperatures is outpaced by the regional warming in the Arctic, said Walt Meier, a sea ice scientist at NASA Goddard.

"It has been a record year so far for global temperatures, but the record high temperatures in the Arctic over the past six months have been even more extreme," Meier said. "This warmth as well as unusual weather patterns have led to the record low sea ice extents so far this year."

NASA tracks temperature and sea ice as part of its effort to understand the Earth as a system and to understand how Earth is changing. In addition to maintaining 19 Earth-observing space missions, NASA also sends researchers around the globe to investigate different facets of the planet at closer range. Right now, NASA researchers are working across the Arctic to better understand both the processes driving increased sea ice melt and the impacts of rising temperatures on Arctic ecosystems.

NASA's long-running Operation IceBridge campaign last week began a series of airborne measurements of melt ponds on the surface of the Arctic sea ice cap. Melt ponds are shallow pools of water that form as ice melts. Their darker surface can absorb more sunlight and accelerate the melting process. IceBridge is flying out of Barrow, Alaska, during sea ice melt season to capture melt pond observations at a scale never before achieved. Recent studies have found that the formation of melt ponds early in the summer is a good predictor of the yearly minimum sea ice extent in September.

"No one has ever, from a remote sensing standpoint, mapped the large-scale depth of melt ponds on sea ice," said Nathan Kurtz, IceBridge's project scientist and a sea ice researcher at NASA Goddard. "The information we'll collect is going to show how much water is retained in melt ponds and what kind of topography is needed on the sea ice to constrain them, which will help improve melt pond models."

Operation IceBridge is a NASA airborne mission that has been flying multiple campaigns at both poles each year since 2009, with a goal of maintaining critical continuity of observations of sea ice and the ice sheets of Greenland and Antarctica.

At the same time, NASA researchers began in earnest this year a nearly decade-long, multi-faceted field study of Arctic ecosystems in Alaska and Canada. The Arctic-Boreal Vulnerability Experiment (ABoVE) will study how forests, permafrost and other ecosystems are responding to rising temperatures in the Arctic, where climate change is unfolding faster than anywhere else on the planet.

ABoVE consists of dozens individual experiments that over years will study the region's changing forests, the cycle of carbon movement between the atmosphere and land, thawing permafrost, the relationship between fire and climate change, and more.

Study: Banning fishing in parts of the ocean isn't enough to save biodiversity. A University of Washington fisheries professor argues this week that saving biodiversity in the world's oceans requires more than banning fishing with marine protected areas, or oceanic wilderness areas. In a three-page editorial published this week in the journal <a href="http://www.earth.com/news/wisdom-changes-end-life/"><em>Nature</em></a>, he argues that this increasingly popular conservation strategy is not as effective as properly managing recreational and commercial fisheries. "There's this idea that the only way you can protect the ocean is by permanently closing parts of the ocean to fishing, with no-take areas," said Ray Hilborn, a professor in the UW's School of Aquatic and Fishery Sciences. "You protect biodiversity better by regulating fisheries over the country's entire economic zone."

Marine protected areas have grown in popularity since the early 2000s. Recent examples include an area twice the size of Texas in the central Pacific established in 2014 by President Barack Obama, and a proposal to close 25 percent of the Seychelles' exclusive economic zone, an island nation off Africa's east coast. Study: Banning fishing in parts of the ocean isn't enough to save biodiversity

Several environmental organizations have set a longer-term goal of making 30 percent of the world's oceans into no-take marine protected areas by the year 2030. But Hilborn believes this is not the best way to protect global marine ecosystems.

"If the problem is overfishing or bycatch, then fisheries management is much more effective than establishing <a href="https://en.wikipedia.org/wiki/NASA">MPAs</a> because you regulate the catch over the entire economic zone," Hilborn said. "I don't see how anyone can defend MPAs as a better method than fisheries management, except in places where you just can't do management."

In countries with functioning fisheries management systems, Hilborn believes, conservationists and the fishing industry should work together on large-scale protection of marine biodiversity and sensitive marine habitats. Study: Banning fishing in parts of the ocean isn't enough to save biodiversity

For example, changes in fishing practices that allowed "dolphin-safe tuna" have cut dolphin deaths in the eastern Pacific by almost 100 times between 1986 and 1998, the article notes.

"You could never have reduced dolphin deaths that much by simply closing part of the ocean to fishing," Hilborn said.

He argues that working with the fishing industry to modify what types of gear are used and when and where different species are allowed to be caught can make more of a difference than establishing new marine protected areas.

"In Alaska, for example, more than 50 percent of the continental shelf waters are closed to specific kinds of fishing gear and the entire shelf is covered by species-specific catch restrictions," he writes. "This is much more protection than could be offered by turning 30 percent of the region into MPAs."

Hilborn said he worries that marine protected areas are being created without specific objectives, lacking input from affected communities, and without analysis of the larger-scale effects. Closing one area to fishing will just shift the pressure to a different area, Hilborn said, or cause people to seek other, more environmentally harmful sources of food.

In early September, world leaders will meet in Hawaii for the high-profile World Conservation Congress, held every four years by the International Union for Conservation of <em>Nature</em>. Hilborn hopes his article will prompt discussion about priorities for preserving the health of marine environments.

"The modern conservation movement is places too much emphasis on protected areas," Hilborn said. "The focus needs to shift. We can better protect biodiversity, and still provide food, by looking to fisheries management as the first defense."

Scientists: Tropical cyclones will become stronger as temperatures warm. Powerful tropical cyclones like the super typhoon that lashed Taiwan with 150-mile-per-hour winds last week and then flooded parts of China are expected to become even stronger as the planet warms. That trend hasn't become evident yet, but it will, scientists say.

So far, the warming effects of greenhouse gases on tropical cyclones have been masked, in part by air pollution.

Over the past century, tiny airborne particles called aerosols, which cool the climate by absorbing and reflecting sunlight, largely cancelled out the effects of planet-warming greenhouse gas emissions when it came to tropical storm intensity, according to a new scientific review paper published this week in the journal <em>Science</em>. That might sound like a good thing, but many of those particles came from the burning of fossil fuels and wood, and contributed to acid rain, smog and lung damage. As vehicles and power plants added filters and scrubbers to reduce their impact on human health, levels of man-made aerosols in the atmosphere began to decline. At the same time, greenhouse gas concentrations continued to rise.

That compensating effect won't continue if greenhouse gas warming keeps increasing, the scientists write. Using model simulations, they provide new calculations of the cancelling effects of aerosols and greenhouse gases on tropical cyclones worldwide. They also take a closer look at the still-developing understanding of how climate change will affect tropical cyclones, also known regionally as typhoons or hurricanes.

"The fact that global warming's fingerprints don't yet jump out at us when we look at hurricanes isn't surprising - it's what current science tells us we should expect," said lead author Adam Sobel, a professor at Columbia University's Lamont-Doherty Earth Observatory and School of Engineering. "The same science tells us that those fingerprints will show up eventually in more ultra-powerful storms."

<strong>Increasing potential intensity</strong>

The scientists examined a wide range of published analyses of tropical cyclone data and computer modeling, looking specifically at potential intensity, which predicts the maximum intensity that tropical cyclones could reach in a given environment. Their new global calculations of the cancelling effect follow a 2015 study led by Lamont's Mingfang Ting, with Suzana Camargo, also a coauthor on the new paper, that showed similar effects over the North Atlantic, where hurricanes that make landfall in the United States form.

Many factors contribute to a tropical cyclone's intensity. At the most basic, the storm's convective strength - the boiling motion of air rising from the ocean surface to the atmosphere - depends on the temperature difference between the surface ocean and the upper atmosphere. Computer models that simulate the physics of tropical cyclones suggest that this difference should increase as the climate and sea surface temperatures warm, and that tropical storm strength should increase with it.

Less well understood is how climate change should influence the number of tropical cyclones that form each year. Computer models indicate that while the total number of cyclones should decline in a warming climate, more intense, highly destructive storms like Super Typhoon Nepartak are likely to become more common.

We have seen harbingers of that change in recent years: <a href="http://www.earth.com/image/typhoon-lingling-moves-through-the-yellow-sea/">Typhoon</a> Haiyan, also known as Yolanda, killed more than 6,300 people as it devastated parts of the Philippines as a Category 5 storm in 2013. Last year, Hurricane Patricia became the second most-intense tropical cyclone on record when its sustained winds reached 215 mph before weakening to hit Mexico with winds still powerful at 150 mph.

The scientists' review finds that the largest increases in tropical cyclone potential intensity are expected to be at the margins of the tropics, particularly in the Atlantic and Pacific. The amount of rain that tropical storms bring is also expected to increase as the planet warms, due to increasing water vapor; and coastal flooding from storm surges that accompany tropical storms are expected to become more of a problem as sea levels rise. The scientists also describe a shift in tropical cyclone tracks toward the margins of the tropics, noting that it is unclear if the shift is a response to warming. Simulations for the western North Pacific suggest that it is, at least in part.

<strong>Detecting the influence of climate change</strong>

Two factors make it difficult to detect greenhouse gas-related trends in tropical cyclone intensity, as the authors explain.

One is the influence of aerosols. Model calculations indicate that aerosols have about twice the effect of greenhouse gases on a tropical cyclone's potential intensity. So while greenhouse gas levels have been greater than aerosol levels for many decades in terms of absolute magnitude - which is why the planet has warmed by about 1.5?F since the Industrial Revolution - they have only recently surpassed the cooling effect of aerosols in terms of their influence on tropical cyclone intensity.

The other challenge is natural variability. Tropical cyclones are relatively rare - the world averages around 90 per year - and that number fluctuates from year to year and decade to decade, due in large part to natural causes. It is statistically difficult to detect long-term trends within that large natural variability, Sobel said. Satellite records that can monitor tropical storms worldwide also only go back to the 1970s.

Scientists at Lamont, including Sobel, Camargo and coauthors Allison Wing and Chia-Ying Lee, are using both observations and computer models to expand understanding of how tropical cyclone behavior has changed and the physical mechanisms by which climate affects extreme weather. Among other projects, they are developing a tropical cyclone risk model that can be used in urban planning that incorporates climate factors in determining the probability of a tropical cyclone making landfall at a given location.

Atrazine has been very good at killing weeds in corn fields for more than 50 years. But some of the properties that make it a successful herbicide, such as its persistence in the soil and ability to be transported in water, also lead to concerns about potential environmental impact. At both federal and state levels, increasing restrictions on atrazine use has the sweet corn industry wondering about alternatives.

"The list of herbicides available for use on sweet corn is much more limited than field corn, so historically sweet corn growers and processors have relied heavily on atrazine. They have been in need of alternatives, but the call for those alternatives has gone largely unanswered," says University of Illinois and USDA Agricultural Research Service weed scientist Marty Williams.

Williams and a team of researchers from <a href="http://www.earth.com/news/unequal-treatment-protestors/">Oregon</a> and Minnesota polled growers and processors to find out the weed management tactics they would consider using as alternatives.

"At the onset of this project, we engaged the processing sweet corn industry. We knew alternatives to atrazine had to be pragmatic. Are weed biocontrol agents an option? Would a cover crop solve the problem? Is handweeding cost-effective? In this case, no, no, and no. They wanted us to develop systems that integrated mechanical control with existing herbicide technology," Williams recalls.

Most of the alternative herbicides they tried were already registered for use in sweet corn, and came from different herbicide classes than atrazine. The research team settled on 16 treatments, including three standard atrazine-containing treatments. Treatments were compared in sweet corn fields in Illinois, <a href="https://en.wikipedia.org/wiki/Minnesota">Minnesota</a>, and Oregon over four years.

"Standard treatments containing atrazine and mesotrione applied postemergence provided the best control, and resulted in crop yields comparable to the weed-free check," Williams states. "In our study, alternative treatments with tembotrione applied postemergence with or without interrow cultivation were similar in weed control and crop yield to atrazine-containing treatments."

Interestingly, interrow cultivation sometimes stimulated weed emergence, thereby reducing effectiveness of the tactic in certain fields. The researchers also found that several other atrazine-free treatments worked well, but only in Oregon.

"Oregon fields were dominated by small-seeded weed species that were controlled by more products than the large-seeded weeds more common in the Midwest, such as velvetleaf and giant ragweed," Williams explains.

Tembotrione was used to represent the HPPD inhibiting class of herbicides, which includes other efficacious herbicides such as topramezone, mesotrione, and bicyclopyrone. This mode of action was developed most recently, but some weeds are already becoming resistant to HPPD inhibitors.

"As with most herbicides, misuse of the alternatives to atrazine could select for herbicide resistant weed populations. Nonetheless, it is possible to grow sweet corn without atrazine using an approach that sweet corn growers and processors consider adoptable," Williams notes.

<p class="ap-story-p">Beijing: Air quality has improved in 2016. Beijing's notoriously awful air quality improved significantly in the first half of the year, with actions taken to curb the city's heavy pollution having a positive effect, officials in the <a href="http://www.earth.com/news/ancient-people-elongated-skulls/">Chinese</a> capital said.</p>
<p class="ap-story-p">Concentrations of microscopic PM2.5 - small, inhalable particles that can penetrate deep into the lungs and are considered a reliable gauge of air quality - dropped by 17.9 percent in the first six months against the same period last year, the Municipal Environmental Protection Bureau said on its website late Monday. Beijing: Air quality has improved in 2016</p>
<p class="ap-story-p">The number of days in which air quality was rated good grew by 19, to 107, while the number of days with heavy pollution fell by two, to 14, the bureau said.</p>
<p class="ap-story-p">The ongoing closure of 174 heavily polluting Beijing factories was among the reasons given for the improvement, along with the switching of 463 communities from coal to alternative energy sources, the retirement of tens of thousands of exhaust-spewing cars, trucks and buses, and the addition of 6,803 vehicles running purely on electricity.</p>
<p class="ap-story-p">"Since the start of the year, the entire city has assiduously implemented the key tasks of the clean air action plan," the bureau said. "The improvement in air quality citywide has been obvious."</p>
<p class="ap-story-p">With more than 21 million people, Beijing has struggled with the ills of most modern cities, including snarled traffic and a shortage of affordable housing. Air pollution, however, has perhaps had the biggest impact on quality of life, with schools closed and outdoor activities curtailed on particularly bad days. Air pollution was also cited as a concern by evaluators ahead of Beijing being awarded the 2022 Winter Olympics.</p>
<p class="ap-story-p">Actions taken by the central government, especially since 2014, have borne fruit, however, with overall pollution levels in Beijing down in each of the past two years.</p>
<p class="ap-story-p">Coal consumption is the biggest source of air pollution in China. The country is now the world's largest emitter of greenhouse gases, although the United States far exceeds it on a per capita basis.</p>
<p class="ap-story-p">Researchers at Germany's Max Planck institute have estimated that smog has led to 1.4 million premature deaths per year in China, while the nonprofit group Berkeley Earth in <a href="https://en.wikipedia.org/wiki/California">California</a> has had a higher figure, 1.6 million.</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>

<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>

<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>

<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>Today's <strong>Video of the Day</strong> from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. </p>



<p>"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."</p>



<p>"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.</p>



<p>"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”</p>
