Folschviller, a quiet town in France’s Moselle region, just handed the energy world a surprise it didn’t see coming. Beneath land once dotted with coal pits lies an estimated 46 million tons of natural hydrogen, a cache large enough to stir fresh conversations about how the planet powers itself. 



The figure tops half of today’s yearly gray hydrogen output, yet it carries none of the pollution burden that shadows the industry’s status quo.



The discovery lands at a moment when clean fuels are in high demand, but often too pricey or too dirty to use at scale. Here, nature has done the hard work. 



Instead of relying on factories or <a href="https://www.earth.com/news/more-warnings-fossil-fuels-are-causing-climate-health-and-biodiversity-crises/" target="_blank" rel="noreferrer noopener">fossil fuels</a>, this hydrogen has sat untouched until recent drilling exposed it - and the timing could not be more convenient for a world bent on cutting emissions.



<h2 class="wp-block-heading" id="h-finding-the-natural-hydrogen-motherlode">Finding the natural hydrogen motherlode</h2>



A research team hunting for methane struck a different kind of treasure at a depth of 4,101 feet. The drill core showed pockets of colorless gas, soon confirmed as hydrogen. 



Only after that eureka moment did word spread that the deposit belonged to the GeoRessources laboratory and France’s National Center for Scientific Research, or <a href="https://www.cnrs.fr/en" target="_blank" rel="noreferrer noopener">CNRS</a>.



The scientists were looking for clues to ancient hydrocarbons when the readings changed. They realized the reservoir might reshape regional energy plans, prompting fresh tests and economic modeling. 



Early estimates calculate the value of the find at roughly $184 billion, based on a conservative $4.00 per kilogram, or $4,000 per ton.



<h2 class="wp-block-heading" id="h-why-natural-white-hydrogen-matters">Why natural white hydrogen matters</h2>



Industry labels hydrogen by color to signal how it is produced. <a href="https://www.earth.com/news/green-hydrogen-energy-production-just-got-a-lot-easier/" target="_blank" rel="noreferrer noopener">Green hydrogen</a> splits water with renewable electricity, a clean method but one that still costs more than most companies can swallow. 



<a href="https://www.earth.com/news/shape-shifting-membrane-could-be-the-key-to-cleaner-energy/" target="_blank" rel="noreferrer noopener">Gray hydrogen</a> strips the element from natural gas, leaving behind carbon dioxide. White hydrogen skips both paths; it forms naturally underground and carries no direct carbon penalty.



That built‑in advantage tackles two headaches at once. It avoids the power‑hungry electrolysis required for green hydrogen and sidesteps the emissions from gray hydrogen’s fossil‑fuel origin. 



If engineers can lift the gas to the surface without leaks, factories could switch to a cleaner feedstock overnight.



<h2 class="wp-block-heading" id="h-simple-chemistry-at-work">Simple chemistry at work</h2>



White hydrogen begins when water seeps into iron‑rich rocks deep below ground. A chemical reaction splits the water molecules, releasing hydrogen gas that drifts into cracks and traps. 



Over thousands of years, those pockets grow. In some parts of the world - Mali, Russia, and isolated U.S. basins - gas even seeps to the surface, lighting small bush fires or fueling village stoves.



The French deposit likely formed the same way. Because it already sits in a pure state, producers can bypass the energy‑intensive clean‑up steps that plague other hydrogen sources. The gas emerges ready for pipelines, fuel cells, or industrial burners.



<h2 class="wp-block-heading" id="h-counting-dollars-and-emissions">Counting dollars and emissions</h2>



Hydrogen priced at $4.00 per kilogram could make low‑carbon steel, ammonia, and long‑haul trucking far cheaper than current green hydrogen models allow. 



With a price tag of $184 billion, the Moselle reserve reads like an open invitation to investors. Unlike oil or coal, its combustion releases only water vapor, trimming the environmental tab to nearly zero.



Yet money alone does not sway climate math. 



Replacing gray hydrogen with natural hydrogen at this scale would cancel about 130 million tons of <a href="https://www.earth.com/news/global-co2-emissions-rise-as-nations-tackle-fossil-fuel-dependence/" target="_blank" rel="noreferrer noopener">carbon dioxide</a> each year - the amount those gray plants now emit. That single swap could equal the annual emissions of a midsize European country.



<h2 class="wp-block-heading" id="h-local-benefits-for-france">Local benefits for France</h2>



Lorraine’s history is steeped in <a href="https://www.earth.com/news/u-s-coal-ash-holds-tons-of-rare-earth-elements-worth-8-4-billion/" target="_blank" rel="noreferrer noopener">coal</a> and steel. Many mines closed decades ago, leaving empty shafts and economic scars. 



Tapping white hydrogen offers a chance to revive the region with new jobs in drilling, pipeline work, and gas processing. Local officials already talk about training programs to shift miners to cleaner tasks.



Energy security matters, too. France imports much of the <a href="https://www.earth.com/news/natural-gas-isnt-as-clean-as-we-think/" target="_blank" rel="noreferrer noopener">natural gas</a> that feeds its industries. A domestic supply of hydrogen would shield buyers from price swings and geopolitical shocks, giving planners a dependable baseline fuel.



<h2 class="wp-block-heading" id="h-abundance-of-natural-hydrogen">Abundance of natural hydrogen</h2>



About midway through the project, lead scientist Dr. Jacques Pironon put the discovery into plain terms for Interesting Engineering.



“Our research suggests that natural hydrogen could be far more abundant than previously thought. If we can find efficient ways to extract and use it, we may have a powerful new tool in the fight against climate change," Dr. Pironon enthused.



“We need to understand the full potential of these hydrogen reservoirs and develop safe, efficient methods to extract them.” 



His caution reflects the field’s youth; few commercial wells exist, and regulators still draft rules to prevent leaks or <a href="https://www.earth.com/news/nearly-100-million-americans-exposed-to-contaminated-drinking-water/" target="_blank" rel="noreferrer noopener">groundwater problems</a>.



<h2 class="wp-block-heading" id="h-global-race-for-natural-hydrogen-begins">Global race for natural hydrogen begins</h2>



Other countries have noticed. Australia’s government earmarked funds to map its iron‑rich crust, while U.S. explorers study gas seeps in Kansas and Nebraska. 



Some researchers even ask whether white hydrogen replenishes continuously, like an underground fountain. If future tests show steady recharge, the fuel could edge closer to the definition of renewable.



Tech startups are also watching. Companies that design hydrogen turbines, storage tanks, and refueling stations see a chance to leapfrog the cost barriers that hold back wider adoption. 



Lower feedstock prices could make hydrogen trucks and ships more attractive than their diesel rivals.



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



France has a long way to go with this jackpot, and the next move is a big one. Pilot wells will test flow rates, pressure behavior, and safety gear. 



Should those numbers hold, commercial extraction could start within a few years, turning Folschviller into a living laboratory for natural hydrogen. 



Success might prompt copycat surveys worldwide, nudging the energy mix toward a gas that arrives carbon‑free straight from the ground.

<div class="img-wrapper">New technique helps scientists study Antarctic sea ice and glaciers. New technique helps scientists study Antarctic sea ice and glaciers Historic changes to Antarctic sea ice could be unraveled using a new technique pioneered by scientists at Plymouth University. It could also potentially be used to demonstrate past alterations to glaciers and ice shelves caused by climatic changes, a study published in Nature Communications suggests.</div>
The new method builds on an existing technique, also developed by Plymouth University over the last 10 years, which identified a means by which scientists could measure changes to sea ice in the Arctic.

That has already led scientists to reveal periods when the <a href="http://www.earth.com/video/winter-habitat-found-under-the-arctic-ice/">Arctic</a> was previously ice free during summers, and when sea ice first expanded to is modern extent. Also New technique helps scientists study Antarctic sea ice and glaciers have shown in image above the amount of beauty it creates.

Simon Belt, Professor of Chemistry at Plymouth University and lead author on the study, said: "In addition to allowing us to unlock historical changes to Antarctic sea ice, our new method also has the potential to provide further insights into other critical climatic features that may have changed in the past. Indeed, sea ice around the Antarctic coastline is strongly influenced by nearby glaciers and ice shelves, both of which contribute to increased global sea level when they melt. Therefore, our new approach may also permit a much broader spectrum of climatic changes to be unraveled in the future."

The previous technique is based on the presence of IP25 (ice proxy with 25 carbon atoms), a lipid chemical made solely by microalgae that live in the bottom of Arctic sea ice. When the ice melts, the algae and its lipids fall into the sediments which can be recovered, dated and analysed.

IP25 does not exist in the Antarctic, but scientists from Plymouth - working with colleagues from Hanyang University, the Korea Polar Research Institute, the British Antarctic Survey and Isoprime Limited - have discovered a related chemical in the Southern Ocean. Although these glaciers are thick and beautiful they tend to melt down a lot come spring time. Also the ice glaciers that build up over the winter time show how awesome nature is by creating these thickly built up sculptures.

Analysis of surface sediments covering different regions of Antarctica - including the Weddell Sea, the Antarctic Peninsula, the Bellingshausen Sea and the Ross Sea - showed the presence of IPSO25 (ice proxy for the Southern Ocean with 25 carbon atoms) in nearly all cases. <a href="https://en.wikipedia.org/wiki/NASA">NASA's</a> view of it all.

Its source, Berkeleya adeliensis, is a widespread and commonly occurring constituent of microalgae inhabiting Antarctic sea ice, which explains why IPSO25 is so common in the sediments.

The paper concludes: "The identification of IPSO25 in the Antarctic sea ice diatom Berkeleya adeliensis likely ensures that future interpretations of the sedimentary occurrence of this sea ice proxy can be made with greater confidence and in more detail. Thus, in addition to representing a qualitative measure of the past occurrence of Antarctic landfast ice during late spring/summer, our findings indicate that variability in sedimentary IPSO25 potentially provides further insights into changes to ice shelf and glacial melt processes in long-term records."

<div>Hurricane Madeline nearing the Hawaiian Islands NASA-NOAA's Suomi NPP and NOAA's GOES satellites showed major Hurricane Madeline nearing the Hawaiian Islands. An animation of satellite imagery showed the movement of Madeline and nearby Hurricane Lester over a two day period.</div>
<div>

At 7:25 p.m. EDT (23:25 UTC) on Aug. 29, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of major Hurricane Madeline. The storm's eye extended up to 13 nautical miles wide in diameter and Madeline appeared very well organized.

By 11 p.m. EDT (5 p.m. HST) the storm was classified as a major hurricane when maximum sustained winds reached 115 mph (185 kph). Madeline had become a Category 3 hurricane on the Saffir-Simpson Wind Scale.

On Aug. 30, Madeline has sparked a hurricane watch for Hawaii County, Hawaii.

At NASA/NOAA's GOES project office at NASA's Goddard Space Flight Center in Greenbelt, Maryland, an animation of NOAA's GOES-East satellite imagery from Aug. 28 to Aug. 30 was created. The animation showed the movement of Hurricane Madeline intensify from a Category 2 to Category 4 hurricane. To the east of Madeline, Hurricane Lester was moving through the Eastern Pacific Ocean.

At 8 a.m. EDT (2 a.m. HST/1200 UTC), the center of Hurricane Madeline was located near 19.3 degrees north latitude and 147.7 degrees west longitude. That puts the eye of Madeline about 490 miles (790 km) east of Hilo, Hawaii and 680 miles (1,095 km) east of Honolulu, Hawaii.

NOAA's Central Pacific Hurricane Center (CPHC) said that Madeline is moving toward the west near 9 mph (15 kph) and this motion is expected to become west southwesterly late today through early Thursday. On the forecast track, the center of Madeline will pass dangerously close to the Big Island Wednesday and Wednesday night. The estimated minimum central pressure is 950 millibars.

Maximum sustained winds are near 130 mph (215 kph) with higher gusts. Madeline is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast through early Thursday. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km).

Hurricane conditions are possible over Hawaii County on Wednesday, Aug. 31, and ocean swells are expected to reach the Hawaiian Islands over the next couple of days, possibly becoming damaging along some coastlines Wednesday and Thursday.

NOAA's CPHC said that heavy rains associated with Madeline may reach Hawaii County on Wednesday, and may impact other <a href="http://www.earth.com/earthpedia-articles/hawaiian-flower-identification-for-beginners/">Hawaiian</a> Islands later Wednesday into Friday. Madeline is expected to produce total rain accumulations of 5 to 10 inches, with isolated maximum amounts near 15 inches, especially over windward portions of the Big Island. This rainfall may lead to dangerous flash floods and mudslides.

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. 



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

</div></figure>



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



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



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. 



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).



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



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.



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.



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>.

Today’s Video of the Day 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.



“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. 



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.



“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;



“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.”



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



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.

Today's Video of the Day 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. 



"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."



"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.



"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.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.

Today's Video of the Day from the <a href="http://www.esa.int/">European Space Agency</a> features Qeshm Island in the Strait of Hormuz. This strait provides the only sea passage from the Persian Gulf to the open ocean.



Qeshm is separated from the Iranian coast by the Clarence Strait, also known as Khuran.&nbsp;The Hara Forest Protected Area is a network of shallow waterways and forest located between the island and the mainland. This protected region is home to sea turtles, snakes, and more than 150 species of migrating birds.



Qeshm is famous for its wide range of&nbsp;ecotourist&nbsp;attractions, such as the&nbsp;Hara marine forests. According to environmentalists, about 1.5 percent of the world birds and 25 percent of Iran's native <a href="https://www.earth.com/news/female-hummingbirds-avoid-sexual-harassment-by-looking-like-males/">birds</a> annually migrate to the forests, which are the first national geo park in Iran.



Tourists are also drawn to the island to see an age-old Portuguese&nbsp;fort, historic mosques, the&nbsp;Seyyed Mozaffar&nbsp;and&nbsp;Bibi Maryam&nbsp;shrines, and the "Valley of Stars."



The average temperature on the island is 81 degress and the region is often hot and humid. From June to August, the island is described as being oppressively hot. The ideal time to visit is during the winter season.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Inhambane Bay in southeast Mozambique.&nbsp;



"Inhambane Bay is a deep inlet into which the small Mutamba River flows," says ESA. "On one side of the bay lies the historical city of Inhambane, capital of the Inhambane Province, while the sister city of Maxixe, the economic capital of Inhambane, sits across from it. The province is the second largest grower of cashews, after Nampula, and it also produces coconut and citrus fruits."



The beaches of Barra and Tofo are popular with tourists. There are also coral reefs along the long coastline of Inhambane, making it an ideal destination for scuba diving and snorkeling.



"Mozambique’s extensive coastline heightens the country’s vulnerability to tropical cyclones that develop in the Indian Ocean as well as storm surge flooding," says ESA.



"More than half of the population lives in low lying coastal areas, putting communities at risk. Inhambane Bay was dangerously close to where Cyclone Idai made landfall in 2019 causing widespread destruction to the country."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency </a>&nbsp;features the Kangerlussuaq Glacier, one of the largest tidewater outlet glaciers in Greenland. The glacier is located on the east coast of the Greenland ice sheet.



As human-induced climate change continues to drive up temperatures, global ice loss is accelerating at an alarming rate. ESA reports that, over the past decade alone, 3.5 trillion tons of ice have melted from the Greenland ice sheet. This is enough to cover the UK with meltwater 15 meters deep.



Based on satellite imagery, researchers determined that Kangerlussuaq entered a new phase of rapid retreat and acceleration in 2017. In their study, published in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00123/full">Frontiers in Earth Science</a>,&nbsp; the experts report that the glacier's ice front is now at its most retreated position since the early 20th century.



"Given Kangerlussuaq’s previous impacts on both the magnitude and pattern of ice sheet wide mass loss, we predict that its new phase of retreat, acceleration and thinning will markedly enhance the south-east region’s contribution to increasing discharge from the ice sheet," wrote the study authors.&nbsp;&nbsp;



"More broadly, accurate forecasting of the ice sheet’s contribution to sea level rise will require a deeper understanding of, and responses to, these non-linear ice dynamic processes."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the complex relationship between ocean and climate. ESA's Climate Change Initiative will help us understand how oceans influence the climate and how climate change is impacting the oceans.&nbsp;



"Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate," explains ESA.



"As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life."



The amount of heat and carbon dioxide soaked up by the ocean depends on specific variables, including phytoplankton, temperatures, waves, salinity, and ice cover. Satellites can be used to measure these variables from space.



"From their unique vantage point, satellites provide key information for understanding the complexities of our planet and monitoring environmental issues," says ESA.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the importance of monitoring the shape of the sea surface, which is constantly changing. These observations have many applications, such as ship routing, <a href="https://www.earth.com/news/the-modem-ocean-is-a-tough-place-for-whales-to-survive/">ocean</a> current forecasting, and debris tracking.



"A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely," reports ESA.



"The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of the sea surface at very low angles. At these so-called grazing angles, waves and surface roughness have very little impact on the reflection process; the sea surface acts as a very smooth mirror."



Estel Cardellach is the principal investigator at the Institute for Space Studies of Catalonia, who first submitted the idea for the project.



“In a mirror-like reflection the phase of the signal can be tracked – it is continuous," said Cardellach. "Different surface heights result in different phase measurements. It gives a very precise measurement of the surface altitude at a few centimetres’ precision.”



The researchers developed a GNSS receiver and set up an experiment in the Balaeric Islands to collect signals from the receiver that were reflected off the sea surface. Ultimately, these signals will provide improved measurements of the shape of the sea surface.
