Today's Image of the Day from NASA Earth Observatory features a blanket of dust over the Tarim Basin - a vast, arid region in northwestern China. 



Mountain peaks are visible through a break in the dust. These peaks are part of Tekilik Shan, a subrange of the Kunlun Mountains.



Though not as widely known as some other mountain ranges in the area, Tekilik Shan plays a significant role in shaping local <a href="https://www.earth.com/news/extreme-weather-is-pushing-nature-toward-a-breaking-point/" target="_blank" rel="noreferrer noopener">weather</a> patterns and geography.



Its snow-covered peaks can rise above 13,000 feet, contributing to the dramatic elevation differences that define the basin’s borders.

Spring marks the height of <a href="https://www.earth.com/news/sahara-desert-dust-storms-carry-harmful-bacteria-and-fungi-around-the-globe/" target="_blank" rel="noreferrer noopener">dust storm</a> activity in the Tarim Basin, particularly in its southern region.&nbsp;



“It’s a time of year when regional wind patterns shift in ways that cause winds and storm systems to sweep in from the northwest,” noted <a href="https://earthobservatory.nasa.gov/images/154126/a-curtain-of-dust-over-the-tarim-basin" target="_blank" rel="noreferrer noopener">NASA</a>.



“In early spring, when landscapes in this region are especially dry and have minimal vegetation, land surfaces warm rapidly under the Sun’s heat every morning, fueling convection that can help loft dust upward by the afternoon.”



<h2 class="wp-block-heading" id="h-fingerlike-dust-formations-nbsp">Fingerlike dust formations&nbsp;</h2>



Satellite images revealed dust formations with fingerlike shapes that mirrored the landscape below. These projections aligned with valleys, which channeled and directed the airborne dust.&nbsp;



Ralph Kahn is an atmospheric scientist at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder and scientist emeritus at NASA’s Goddard Space Flight Center.



According to Kahn, the dust may have been “self-lofting.” In this process, sunlight heats recently stirred-up surface dust, creating pockets of convection that lift it even higher into the air.



This interpretation is supported by hourly observations from Japan’s Himawari-9 geostationary satellite, which showed dust gradually rising into the Tekilik Shan throughout the day. By late afternoon, the storm had grown dense enough to obscure the mountains.&nbsp;



<h2 class="wp-block-heading" id="h-decline-in-atmospheric-dust">Decline in atmospheric dust</h2>



Long-term satellite data from MODIS suggest that <a href="https://www.earth.com/news/dust-storms-in-the-gulf-of-alaska-help-shape-the-global-climate/" target="_blank" rel="noreferrer noopener">atmospheric dust</a> levels in this region have declined by about 1.5 percent each year since the early 2000s.&nbsp;



NASA researcher Hongbin Yu attributes this trend mainly to springtime changes - such as altered wind speeds, <a href="https://www.earth.com/news/how-soil-moisture-can-predict-severe-storms/" target="_blank" rel="noreferrer noopener">soil moisture</a>, or vegetation cover - rather than shifts in other seasons.



<h2 class="wp-block-heading" id="h-rainfall-in-the-tarim-basin-nbsp">Rainfall in the Tarim Basin&nbsp;</h2>



“The <a href="https://www.britannica.com/place/Takla-Makan-Desert" target="_blank" rel="noreferrer noopener">Takla Makan Desert</a> is one of the driest, most barren expanses on Earth. Flanked by mountain ranges on three sides and parched by the resulting <a href="https://glossary.ametsoc.org/wiki/Rain_shadow" target="_blank" rel="noreferrer noopener">rain shadow</a>, parts of the Tarim Basin receive no more than 10 millimeters (0.4 inches) of rain per year,” noted NASA.



“Dust storms can lead to public health problems in populated areas downwind by transporting small particles, bacteria, and viruses that infiltrate human respiratory systems.”&nbsp;



NASA added that dust storms can also affect Earth’s climate by scattering and absorbing incoming solar radiation and changing the properties of clouds.



<h2 class="wp-block-heading" id="h-landscape-of-the-tarim-basin-nbsp">Landscape of the Tarim Basin&nbsp;</h2>



The Tarim Basin is one of the largest endorheic basins in the world, meaning that its rivers do not drain into the sea but instead flow into interior lakes or evaporate.&nbsp;



The basin is encircled by three mountain ranges: the Tien Shan to the north, the Kunlun Mountains to the south, and the Pamirs to the west. These ranges create a powerful rain shadow effect, making the region exceptionally dry.



At the heart of the Tarim Basin lies the Taklamakan Desert, one of the most extreme deserts on Earth. The desert is known for its high dunes, intense temperature swings, and minimal <a href="https://www.earth.com/news/extreme-rainfall-will-wreak-havoc-on-mountain-ranges-as-warming-climate-turns-snow-to-rain/" target="_blank" rel="noreferrer noopener">rainfall</a>.



<h2 class="wp-block-heading" id="h-history-and-geology">History and geology</h2>



Despite its harsh environment, the basin has been historically significant. It was a key section of the ancient Silk Road, with several oases such as Kashgar, Khotan, and Loulan serving as vital trading and cultural centers for centuries.



Geologically, the basin is rich in natural resources, particularly oil and natural gas, and has become a focal point for China's energy exploration and development.&nbsp;



The region’s challenging climate and remote location, however, make infrastructure development and human habitation difficult.&nbsp;



The image was captured on March 27, 2025 by the Operational Land Imager instrument on Landsat 8.

Blanket of dust covers China’s Tarim Basin

Today's Image of the Day from NASA Earth Observatory features a blanket of dust over the Tarim Basin - a vast, arid region in northwestern China.  Mountain peaks are visible through a break in the dust. These peaks are part of Tekilik Shan, a subrange of the Kunlun Mountains. Though not as widely known as some other mountain ranges in the area, Tekilik Shan plays a significant role in shaping local weather patterns and geography. Its snow-covered peaks can rise above 13,000 feet,...

Today's Image of the Day from the European Space Agency features a Copernicus Sentinel-2 photograph of Lake Maracaibo, located in the northwestern part of Venezuela. The lake is a significant geographical and ecological feature of South America. 



Lake Maracaibo is often considered more of a tidal bay due to its direct connection to the Caribbean Sea through the Tablazo Strait. It is one of the oldest lakes on Earth, formed approximately 36 million years ago.



"With an area of over 13,000 sq km, Lake Maracaibo is generally considered the largest lake in South America, although by some estimates it should be considered an inlet of the Caribbean Sea since much of its water is brought in by its direct connection to the ocean," explained <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.



"As a result, the water in the northern part of the lake is rather brackish, while the southern waters are fresh, owing to the many rivers that flow into the lake. The biggest, the Catatumbo River, can be seen entering the lake from southwest, where a large amount of sediment carried by the river appears as a yellowish plume."



<h2 class="wp-block-heading" id="h-the-catatumbo-lightning">The Catatumbo lightning</h2>



The lake is renowned for a unique weather phenomenon - the Catatumbo lightning. This natural spectacle occurs primarily where the Catatumbo River meets the <a href="https://www.earth.com/news/wildfire-smoke-has-affected-almost-every-lake-in-north-america/" target="_blank" rel="noreferrer noopener">lake</a>.



Known as the most persistent lightning storm in the world, it produces frequent and dramatic flashes of lightning, illuminating the night sky for an average of 260 nights per year.



These storms generate thousands of lightning strikes in a single night, making the region one of the most electrified places on the planet. 



The phenomenon is so intense that it has been recognized by the Guinness World Records as the place with the highest <a href="https://www.earth.com/news/lightning-on-earth-can-influence-the-weather-in-space/" target="_blank" rel="noreferrer noopener">lightning</a> activity.



Scientists believe the lightning is influenced by the area's geography and climate, including the warm air rising from the lake and its surrounding mountains.



<h2 class="wp-block-heading" id="h-economical-significance-of-lake-maracaibo">Economical significance of Lake Maracaibo </h2>



Home to one of the world's largest oil and gas reserves, Lake Maracaibo plays an important role in Venezuela’s economy.



The discovery of petroleum in the early 20th century transformed the region into a major oil-producing area, leading to the establishment of numerous oil rigs and platforms. 



However, this economic activity has come at a cost. <a href="https://www.earth.com/news/half-of-the-worlds-largest-lakes-are-losing-their-resilience/" target="_blank" rel="noreferrer noopener">Pollution</a> from oil spills, industrial waste, and agricultural runoff has significantly degraded the lake's ecosystem.



The appearance of a green, slimy algae known as Lemna has further exacerbated environmental concerns, threatening marine life and the livelihoods of local communities.



<h2 class="wp-block-heading" id="h-cultural-ties-to-lake-maracaibo">Cultural ties to Lake Maracaibo </h2>



The cultural significance of Lake Maracaibo is deeply rooted in the traditions and lifestyle of the Indigenous Añu people, who have inhabited its shores for centuries. The Añu, also known as Paraujano, are known for their distinctive stilt houses, called palafitos.



These wooden structures are built directly over the water, connected by walkways or small boats, allowing the Añu to live harmoniously with their aquatic environment. The architectural style of these stilt houses inspired the early Spanish explorers to nickname the region "The Venice of the Americas."



The Añu's way of life is closely tied to the lake. They rely on <a href="https://www.earth.com/news/sustainable-fishing-must-be-redefined-to-halt-ocean-destruction/" target="_blank" rel="noreferrer noopener">fishing</a> as a primary source of food and income, using traditional methods passed down through generations.



For the Añu, the <a href="https://www.earth.com/news/wildfire-smoke-significantly-impacts-lake-ecosystems/" target="_blank" rel="noreferrer noopener">lake</a> is more than a resource - it is the spiritual and cultural foundation of their identity and daily lives. However, modernization and environmental challenges have disrupted this traditional lifestyle. 



The oil industry’s expansion around Lake Maracaibo has led to significant environmental degradation, which threaten the lake's biodiversity and the Añu’s primary sources of sustenance.



<h2 class="wp-block-heading" id="h-lake-maracaibo-and-venezuelan-history">Lake Maracaibo and Venezuelan history</h2>



Lake Maracaibo also played a pivotal role in Venezuelan history, particularly during the Battle of Lake Maracaibo in 1823. 



This naval battle was a decisive conflict in Venezuela’s war for independence from Spain and marked one of the final military engagements of the South American liberation movements led by figures like Simón Bolívar.



Today, the lake represents a remarkable blend of natural beauty, industrial significance, and cultural heritage. 



<h2 class="wp-block-heading" id="h-ongoing-conservation-efforts">Ongoing conservation efforts </h2>



The need to protect the extraordinary environment of Lake Maracaibo is widely acknowledged. Ongoing efforts aim to harmonize ecological conservation with economic development.



Efforts to preserve the Añu culture and the lake's ecosystem have been initiated by local and international organizations. These initiatives focus on promoting sustainable development, preserving Indigenous languages and traditions, and mitigating the environmental damage caused by industrial activities. 



Despite these challenges, the Añu have shown remarkable resilience, maintaining their cultural identity and advocating for their rights and the health of their ancestral lands.

A perfect example of a barred spiral galaxy. Today's Image of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features NGC 613, a galaxy that is located 67 million light years away in the southern constellation of Sculptor. 

The galaxy was first discovered by German-English astronomer William Hershel in 1798. This new image from the Hubble Space Telescope reveals the defined central bar and long arms of NGC 613, which is known as a barred spiral galaxy. A perfect example of a barred spiral galaxy

According to the ESA, about two thirds of spiral galaxies, including our own Milky Way, contain a bar. 

Scientists have recently determined that bars are more common in galaxies now than they were in the past. This discovery provides new insight into the formation and evolution of galaxies.Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequence. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. These are often surrounded by a much fainter halo of stars, many of which reside in globular clusters.

Antarctic iceberg continues to drift close to South Georgia. Today's Image of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> features a giant Antarctic iceberg that has been drifting in the southern Atlantic Ocean since July of 2017.

The iceberg, known as A-68A, was the size of Delaware when it first split from the Larsen C Ice Shelf. For over a month, A-68A has been drifting toward the remote Atlantic island of South Georgia.

The NOAA-20 satellite image shows the iceberg on January 11, 2021, along with two large pieces that broke off in December.

Despite moving very close to South Georgia, A-68A and its smaller ice chunks are not grounded and continue to drift with the currents. Antarctic iceberg continues to drift close to South Georgia. Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres (5,500,000 square miles), it is the fifth-largest continent and nearly twice the size of Australia. At 0.00008 people per square kilometre, it is by far the least densely populated continent. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of 200 mm (7.9 in) along the coast and far less inland; there has been no rain there for almost 2 million years, yet 80% of the world freshwater reserves are stored there,

Earth's warming trend continued in 2020. Today's Image of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> features a map of global temperature anomalies in 2020, which tied with 2016 for the warmest year on record.

The temperature in 2020 was 1.02 degrees Celsius, or 1.84 degrees Fahrenheit, warmer than the baseline average from 1951 to 1980, according to scientists at NASA’s Goddard Institute for Space Studies (GISS). 

“The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend,” said GISS Director Gavin Schmidt. “Whether one year is a record or not is not really that important; the important things are long-term trends. With these trends, and as the human impact on the climate increases, we have to expect that records will continue to be broken.”

Some regions of the world are heating up faster than others, and warming patterns are the most pronounced in the Arctic. Earth's warming trend continued in 2020

According to Schmidt, the region has been warming more than three times as fast as the rest of the globe over the past 30 years. 

“The previous record warm year, 2016, received a significant boost from a strong El Niño,” said Schmidt. “The lack of a similar assist from El Niño this year is evidence that the background climate continues to warm due to greenhouse gases.”

Snow cover persists in Spain after Storm Filomena. Today's Image of the Day from the <a href="https://www.esa.int/">European Space Agency</a> shows snowfall lingering across Spain days after Storm Filomena dumped 20 inches of snow in the capital city of Madrid. 

The storm brought the heaviest snowfall the country has had in five decades, and the hazardous conditions have persisted.

In central Spain, record low temperatures have transformed the snow into ice, causing even more issues.  Spain , officially the Kingdom of Spain (Spanish: Reino de España), is a country in Southwestern Europe with some pockets of territory across the Strait of Gibraltar and the Atlantic Ocean. Its continental European territory is situated on the Iberian Peninsula.  

Its territory also includes two archipelagos: the Canary Islands off the coast of North Africa, and the Balearic Islands in the Mediterranean Sea. The African exclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. Snow cover persists in Spain after Storm Filomena.

In the forests of Madagascar, few animals command attention quite like lemurs - especially when it comes to questions of social hierarchy. 



In many lemur species, it is the females that rule the roost. They dominate food, take prime spots, and often chase, bite, or hit males who get in their way. 



Yet new evidence shows that this aggressive matriarchy is not universal among lemurs, and the key difference may lie in how their brains deploy a single hormone: oxytocin.



<h2 class="wp-block-heading" id="h-gender-equality-and-oxytocin-receptors">Gender equality and oxytocin receptors </h2>



A new study led by <a href="https://duke.edu/">Duke University</a> takes a close look at seven species in the genus Eulemur. Some of these species, such as the blue‑eyed black lemur, operate under rigid female dominance, while others, like the collared lemur, live in more egalitarian groups.



By mapping oxytocin‑binding sites in the animals’ brains, the researchers discovered an intriguing pattern: lemur societies that are more equitable between the sexes possess a denser network of oxytocin receptors. This is especially true in a brain region that governs fear, anxiety, and aggression.



“It’s more of an even playing field,” said first author Allie Schrock, who completed her PhD in evolutionary anthropology at Duke. Her remark contrasts with blue-eyed black lemurs, where dominant females control males through intimidation and strength.



<h2 class="wp-block-heading" id="h-lemur-queens-rule-the-canopy">Lemur queens rule the canopy</h2>



Dominant females in species like the blue‑eyed black lemur do not confine their aggression to maternal defense or resource scarcity. They wield authority even when circumstances are calm, reinforcing status through spontaneous acts of aggression. 



According to senior author Christine Drea, a professor of evolutionary anthropology at Duke, <a href="https://www.earth.com/news/dopamines-role-in-male-aggression-fades-with-fighting-experience/" target="_blank" rel="noreferrer noopener">aggression</a> in these females is often entirely unprovoked, simply to remind others who’s in charge.



“Males let females have priority access to whatever they want,” Drea said. This arrangement places males perpetually on the defensive, ceding first rights to fruiting trees, coveted shade, or safe resting platforms. 



Though unusual to humans, these social structures are common in lemurs - except for notable deviations in the Eulemur genus.



<h2 class="wp-block-heading" id="h-oxytocin-rewires-lemur-behavior">Oxytocin rewires lemur behavior</h2>



To understand how some Eulemur species shed female domination for gender parity, the team turned to preserved brain tissue housed at the <a href="https://lemur.duke.edu/" target="_blank" rel="noreferrer noopener">Duke Lemur Center</a>. These samples came from naturally deceased, flash-frozen lemurs - a vital resource given Madagascar’s endangered primates.



Using autoradiography, a high‑resolution imaging method, the researchers traced where oxytocin molecules could bind throughout the brain. Oxytocin, popularly dubbed the “love hormone,” is well known for its role in mammalian bonding, trust, and social recognition.



The surprising discovery was that egalitarian lemurs had significantly more oxytocin receptors than their female‑dominated cousins. The density spike was most pronounced in the amygdala, a neural hub for emotion regulation.



This pattern suggests that animals with more oxytocin “targets” in emotional centers may experience a dampening of aggression across both sexes, creating conditions favorable to equal status. Rather than males meeting female hostility blow‑for‑blow, the entire group becomes somewhat less confrontational.



For Drea, the data indicate that egalitarian species achieved gender parity by becoming less aggressive towards others overall.



<h2 class="wp-block-heading" id="h-implications-for-human-neuroscience">Implications for human neuroscience</h2>



The study slots neatly into a broader conversation about oxytocin’s influence on lemur social behavior.



In humans, variations in oxytocin signaling have been tied to spectrum disorders such as <a href="https://www.earth.com/news/autism-diagnoses-have-almost-tripled-in-the-us-over-the-past-ten-years/" target="_blank" rel="noreferrer noopener">autism</a>, as well as to patterns of aggression and anxiety. The Duke study shows tiny chemical shifts in receptors can drive major social changes over evolutionary time.



Scientists have already documented an “oxytocin paradox” in which the hormone can foster in‑group bonding but also fuel suspicion or aggression toward outsiders. 



The lemur findings offer a new perspective. When oxytocin receptors increase in brain areas that reduce fear or promote calm, the hormone’s bonding effects may spread more widely. This could help ease social hierarchies rather than intensify them.



<h2 class="wp-block-heading" id="h-a-million-year-experiment">A million‑year experiment</h2>



Genetic evidence indicates that egalitarian Eulemur species diverged from their more dictatorial relatives within the past million years. That is lightning‑fast in evolutionary terms - and hints moderate adjustments in oxytocin pathways may be sufficient to trigger a social overhaul. 



“We have a natural experiment right here,” Schrock said. He added that closely related species provide a powerful test case for linking neurobiology and behavior.



Researchers will study how oxytocin receptors relate to group size, social habits, and the length of pair bonds. “There's a lot more that we can learn from lemurs about how the brain regulates behavior,” Schrock emphasized.



<h2 class="wp-block-heading" id="h-the-story-of-lemur-society">The story of lemur society</h2>



Though lemurs occupy only a sliver of the world’s biodiversity, their social quirks resonate widely. 



Understanding how neurochemical circuitry shapes aggression and <a href="https://www.earth.com/news/bonobos-cooperation-challenges-beliefs-about-human-evolution/" target="_blank" rel="noreferrer noopener">cooperation</a> could inform conservation strategies. It can also improve welfare in captive primates, and even shed light on human behavioral disorders. 



For endangered species, understanding social harmony can aid reintroduction efforts by reducing conflict and improving survival.



In the end, lemurs remind us that social structures - whether matriarchal dominance or egalitarian negotiation - do not exist in a vacuum. They are built on biochemical foundations that evolution can remodel. 



As scientists continue to uncover those hidden mechanisms, the story of lemur society becomes a window into the delicate interplay between brain chemistry, behavior, and the bonds that hold communities together.



The study is published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0647">Biology Letters</a>.

Hormones influence power and peace in lemur society

In the forests of Madagascar, few animals command attention quite...

The world’s ability to feed itself depends heavily on farms. Nitrogen fertilizers are used on farms to grow more crops, ensuring food for people and feed for livestock. But while fertilizers power growth, they also carry an environmental cost that often goes unseen.



When plants can’t absorb all the nitrogen, part of it escapes into the atmosphere as nitrous oxide (N₂O) - a greenhouse gas with staggering potency. It traps nearly 300 times more heat than carbon dioxide (CO₂), warming the Earth far more efficiently.



Despite its low profile, nitrous oxide is a major player in the climate crisis. About 70% of all human-caused nitrous oxide emissions come from agricultural soils.



Yet unlike carbon dioxide, which follows predictable patterns, nitrous oxide behaves more like a phantom - appearing without warning and vanishing just as fast. Understanding when and where these gases emerge is crucial, not only for scientific models but also for practical solutions that reduce <a href="https://www.earth.com/news/global-warming-is-accelerating-beyond-control-as-co2-levels-rise/" target="_blank" rel="noreferrer noopener">emissions</a>.



<h2 class="wp-block-heading" id="h-precision-matters-in-soil-science">Precision matters in soil science</h2>



Until now, most studies on soil greenhouse gases have relied on small sample sizes, limited sampling dates, or simplified assumptions. This makes it difficult to fully understand how much gas escapes from a given field over time.



Conventional methods are often too narrow in scope to capture short-lived or scattered emission events, especially those from nitrous oxide.



A research team from the <a href="https://illinois.edu" target="_blank" rel="noreferrer noopener">University of Illinois Urbana-Champaign</a> set out to overcome these limitations. Their goal was ambitious: to capture the full spatial and temporal complexity of CO₂ and nitrous oxide emissions across real farms, over multiple years, and under typical farming conditions.



The study focused on commercial corn and soybean fields using three tillage practices: conventional, conservation, and no-till.



“Mitigating agricultural soil greenhouse gas emissions can help us meet global <a href="https://www.earth.com/news/food-waste-has-a-surprising-impact-on-climate-change/" target="_blank" rel="noreferrer noopener">climate</a> goals,” said study co-author Chunhwa Jang. The team noted that only a large-scale, high-frequency dataset could paint a reliable picture of what’s happening beneath our feet.



<h2 class="wp-block-heading" id="h-nitrous-oxide-emissions-from-farms">Nitrous oxide emissions from farms</h2>



To monitor soil emissions, the researchers deployed a network of gas sampling points across three large farms in central Illinois. 



Picture these points as tiny smokestacks embedded in the earth. Machines were brought in every week or two to measure gas levels, capturing both CO₂ and N₂O over the full growing seasons of 2021 and 2022.



The experts found that CO₂ <a href="https://www.earth.com/news/many-people-are-willing-to-switch-to-plant-based-food-to-save-the-climate/" target="_blank" rel="noreferrer noopener">emissions</a> were consistent across fields, crops, and years - a reassuring result. It meant scientists could confidently monitor carbon dioxide using lower sampling densities without losing accuracy.



“We found carbon dioxide flux was similar across individual fields, sites, and years, or even between corn and soybean systems,” Jang noted.



Nitrous oxide, however, defied predictability. Its emissions fluctuated wildly, creating what researchers called “hot moments” and “hot spots.” 



One day, a particular point might spike in emissions; the next day, it might go quiet while another area lit up. These chaotic shifts meant that even dense sampling grids sometimes missed key events.



<h2 class="wp-block-heading" id="h-nitrous-oxide-spikes-unpredictability">Nitrous oxide spikes unpredictability </h2>



Unlike CO₂, which was evenly distributed, N₂O hotspots packed a disproportionate punch. Though they occupied just 12–13% of a field, they could account for up to 54% of total <a href="https://www.earth.com/news/2023-climate-change-report-record-high-temperatures-greenhouse-gases-sea-level-rise/" target="_blank" rel="noreferrer noopener">emissions</a>. 



At the Villa Grove site - managed with conventional tillage and planted with continuous corn - the numbers were most extreme.



Data showed that emissions from this site were more than four times higher than those from conservation-managed fields. The combination of heavy nitrogen use and deep tillage likely triggered this spike. 



These methods disturb the soil, release trapped gases, and increase microbial activity - all of which drive nitrous oxide production.



“We may not be able to predict where and when nitrous oxide will spike, but we do know management makes a difference,” said Jang. Fields with continuous corn and traditional tillage saw much higher emissions than those under rotation or conservation practices.



<h2 class="wp-block-heading" id="h-nitrous-oxide-hotspots-on-farms">Nitrous oxide hotspots on farms</h2>



The researchers observed that the timing and method of fertilizer application had major <a href="https://www.earth.com/news/global-co2-emissions-rise-as-nations-tackle-fossil-fuel-dependence/" target="_blank" rel="noreferrer noopener">impacts</a>. For example, fields receiving side-dressed nitrogen along crop rows were more predictable than those with broadcast applications.



Yet even then, randomness crept in. Sometimes, emissions seemed tied to where the fertilizer landed in relation to the gas sampling collar, adding uncertainty to the readings.



To make matters more complex, nitrous oxide hotspots rarely stayed in the same place from one year to the next. In most cases, the spatial patterns changed so much that it was hard to determine whether observed hotspots were real or artifacts of shifting management practices.



The team conducted a detailed analysis of flux consistency across years. They found that only a few sampling points behaved reliably. At many locations, N₂O emissions fluctuated by tenfold or more between years. 



“Spatially and temporally, nitrous oxide was very variable,” Jang reiterated. This variability challenges the way scientists currently model soil gas emissions.



<h2 class="wp-block-heading" id="h-smarter-monitoring-for-n₂o-emissions">Smarter monitoring for N₂O emissions</h2>



The unpredictability of nitrous oxide means traditional monitoring methods fall short. 



Static chambers and small sample sizes are likely to miss the true scale of emissions. If models are based on these limited datasets, they may under- or overestimate field-scale emissions, distorting climate forecasts.



“This project enabled us to capture spatio-temporal and management variation to provide gold-standard data and a platform for validating field-level greenhouse gas emissions,” said co-author DoKyoung Lee.



The team's findings suggest that higher sampling density is essential - especially for nitrous oxide.



Through simulation, the researchers found that to estimate N₂O emissions with less than 25% error, fields need at least 5.6 sampling points per hectare. For CO₂, only 1.6 points are needed. This shows how much more sensitive nitrous oxide emissions are to spatial resolution.



<h2 class="wp-block-heading" id="h-farming-practices-shape-nitrous-oxide-emissions">Farming practices shape nitrous oxide emissions </h2>



One of the study’s key takeaways is the role of management in emission control. Fields under conservation and no-till practices showed both lower emissions and less variability. 



In contrast, conventional systems that disrupt soil and apply nitrogen heavily had not only higher emissions but also larger uncertainties.



In particular, the Villa Grove site stood out. Managed with deep chisel tillage and continuous corn, it produced up to 785 mg/m² of nitrous oxide - nearly nine times the levels observed in rotated soybean systems. This finding aligns with earlier studies and confirms that farming practices strongly shape emission profiles.



Though it’s hard to predict where hotspots will form, choosing crop rotations and reduced tillage can help shrink the overall size of the problem. That gives farmers a way to contribute to climate solutions without sacrificing yields.



<h2 class="wp-block-heading" id="h-climate-models-need-better-data">Climate models need better data</h2>



Accurate field data is the foundation of every global climate model. If the field data is wrong or incomplete, then the predictions those models generate may misguide policies. 



The University of Illinois study provides one of the most robust datasets yet for calibrating climate models with real-world agricultural emissions.



It also points to a broader issue: the tradeoff between scale and control. Gathering high-resolution, multi-year data across large farms is incredibly labor-intensive. 



The researchers suggest that small, well-managed field experiments may be a better way to understand the biological mechanisms behind N₂O emissions. For large-scale estimates, however, grid-based sampling with enough points per hectare seems to be the best path forward.



<h2 class="wp-block-heading" id="h-each-gas-needs-a-unique-strategy">Each gas needs a unique strategy</h2>



This research reveals how differently CO₂ and N₂O behave in agricultural soils. While CO₂ flows steadily, nitrous oxide erupts in bursts, influenced by everything from rainfall to fertilizer timing. That difference demands tailored strategies for each gas.



Reducing agricultural emissions isn’t just about cutting fertilizer or changing crops. It’s about understanding the invisible patterns in the soil and designing systems that can track and respond to them. 



With the right data, tools, and practices, farmers can keep growing food while also shrinking their carbon - and nitrogen - footprint.



This work serves as a reminder that not all gases are created equal, and neither are the ways they move through the soil. Precision, patience, and smarter farming can help us stay grounded - even as we try to cool the skies.

Nitrous oxide emissions erupt from farms in unpredictable bursts

The world’s ability to feed itself depends heavily on farms....

In a quiet corner of the Ecuadorian Andes, a chorus of frogs has sparked a global conversation about environmental justice. These aren’t just any amphibians from Ecuador - they’re symbols of resistance, biodiversity, and legal innovation.



In a recent paper, researchers from the <a href="https://www.uvm.edu/instituteforagroecology" target="_blank" rel="noreferrer noopener">University of Vermont’s Institute for Agroecology</a> and international collaborators explore how Ecuador’s pioneering constitutional recognition of the Rights of Nature is changing the way we think about law, justice, and the planet.



The study presents Ecuador as a test case for reimagining governance systems in favor of both people and ecosystems.



<h2 class="wp-block-heading" id="h-tiny-amphibians-massive-impact">Tiny amphibians, massive impact</h2>



At the heart of this story is the Resistance Rocket Frog - Rana Cohete Resistencia - named by residents of Intag Valley to embody the united effort to protect their land. Though small and seemingly inconspicuous, these <a href="https://www.earth.com/news/amphibians-are-being-pushed-beyond-their-heat-limits/" target="_blank" rel="noreferrer noopener">endangered</a> amphibians from Ecuador became co-plaintiffs in a landmark lawsuit that halted large-scale mining in their habitat.



Supported by community members, biologists, lawyers, and activists, the frogs helped establish one of the most influential legal precedents in Earth system law.



“Translating the Constitutional Rights of Nature into concrete conservation measures is a powerful tool to prevent species extinction in areas threatened by <a href="https://www.earth.com/news/deep-sea-mining-forms-dust-clouds-that-devastate-marine-life/" target="_blank" rel="noreferrer noopener">mining</a>,” said Andrea Terán, an Ecuadorian biologist and co-author of the study.



“Large-scale mining concessions are concentrated in the Andes and their foothills, overlapping with regions of high amphibian endemism and richness. Therefore, having a mechanism to halt this extractive economic model opens the door to exploring alternative relationships with nature and sustainable economic models that support life in the long term.”



Ecuador’s <a href="https://www.earth.com/news/effective-conservation-efforts-key-to-saving-biodiversity/" target="_blank" rel="noreferrer noopener">biodiversity</a> is staggering: the country ranks ninth among the world’s most biologically rich nations, home to as many as 20,000 plant species, nearly 700 amphibians, and over 450 types of mammals. <a href="https://www.earth.com/news/world-frog-day-addressing-environmental-threats-to-frogs/" target="_blank" rel="noreferrer noopener">Frogs</a>, in particular, are considered critical ecological indicators due to their acute sensitivity to pollutants, making them a powerful symbol of environmental health.



<h2 class="wp-block-heading" id="h-recognition-of-nature-s-rights">Recognition of nature's rights</h2>



In 2008, Ecuador became the first country in the world to constitutionally recognize the Rights of Nature, granting ecosystems the legal right to “exist, persist, maintain and regenerate.” Unlike traditional environmental laws, which regulate harm through permits and limits, Rights of Nature laws treat ecosystems as legal subjects, not objects. 



This shift allows non-human life to be represented in court as plaintiffs. In the Llurimagua mining case, legal teams successfully argued on behalf of the forest ecosystem and the species within it, using Ecuador’s constitutional protections.



“In the case of Llurimagua, as explained in the article, the practical applicability of the rights of Nature is demonstrated, showing that these are not merely symbolic declarations but rights with real-world legal effects,” said Mario Moncayo, one of the attorneys on the case.



“The recognition of the rights of nature has allowed individuals and communities to exercise them directly, establishing relevant precedents in the protection of nature.” The legal precedent set by these victories has inspired environmental <a href="https://www.earth.com/news/public-health-and-environmental-justice-the-push-for-electric-trucks-in-cities/" target="_blank" rel="noreferrer noopener">justice</a> advocates around the world.



According to Carlos Varela Arias, a constitutional law professor and co-author of the paper, this framework will enable the design of new strategies and global governance mechanisms to adapt human systems to those of nature, allowing for our survival and peaceful coexistence with the natural environment.



<h2 class="wp-block-heading" id="h-a-global-standard-for-nature-s-rights">A global standard for nature's rights?</h2>



The Ecuadorian model is already echoing beyond its borders. Bolivia’s Mother Earth Law, New Zealand’s legal personhood for the Whanganui River and Te Urewera, and Canada’s recognition of First Nations’ land rights all draw on similar legal reasoning.



Cases in Mexico, India, Chile, Argentina, Brazil, and the United States reflect the growing influence of this movement. To institutionalize these advances, the paper outlines three fundamental dimensions of effective Rights of Nature legislation:



<ol start="1" class="wp-block-list">
<li>Intrinsic worth: recognizing nature’s value independent of human utility.</li>



<li>Guiding principle: using Nature’s rights to steer legal and political decisions.</li>



<li>Enforceability: holding states and citizens legally accountable for harm.</li>
</ol>



The authors also identify the Escazú Agreement - a legally binding treaty signed by 23 Latin American countries including Ecuador. The treaty acts as a promising regional tool to reinforce these rights and protect environmental defenders. 



Despite its ratification in 2021, threats to activists remain dire. According to <a href="https://globalwitness.org/en/" target="_blank" rel="noreferrer noopener">Global Witness</a>, over 2,100 nature defenders have been murdered globally in recent years, with 70% of those killings occurring in just four Latin American countries.



<h2 class="wp-block-heading" id="h-legal-innovation-and-indigenous-wisdom">Legal innovation and Indigenous wisdom</h2>



“The Rights of Nature is a strong and inspiring idea that started in Ecuador,” said Amaya Carrasco Torrontegui, senior author of the paper and a University of Vermont affiliate. “This approach encourages us to see Nature not just as a resource, but as something alive and deserving of care - drawing on Indigenous wisdom and the idea of Pachamama, or Mother Earth.”



Lead author Carlos Andres Gallegos-Riofrío emphasized the transformative potential of these legal frameworks. “A key lesson - especially the coalition that advanced the Llurimagua case - is that there are real alternatives for governing the <a href="https://www.earth.com/news/earth-systems-critical-all-life-on-verge-total-collapse-paris-agreement/" target="_blank" rel="noreferrer noopener">Earth system</a>." 



"These alternatives, to become truly transformative, need society’s active engagement. Only then can they serve as critical tools to help local communities stop activities that harm both people and Nature, globally preventing us from continuing to cross the planet’s safe operating boundaries.”



<h2 class="wp-block-heading" id="h-lessons-from-the-andes"><a></a>Lessons from the Andes</h2>



The success of Ecuador’s Rights of Nature movement demonstrates the power of local activism, coalition-building, and a bold rethinking of legal norms. It also highlights the potential of a “tiny avatar” - like the rocket frog - to symbolize much larger battles over climate, biodiversity, and justice.



With mining blocked in three major projects in the Intag Valley and courts upholding the rights of ecosystems in multiple landmark cases, Ecuador’s approach is proving that environmental justice doesn’t always start in global halls of power. It can also begin in a small village, a forested valley, or the determined leap of a tiny frog.



The study is published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S2589811625000199?via%3Dihub" target="_blank" rel="noreferrer noopener">Earth System Governance</a>.

Does Mother Nature have rights? A tiny frog has joined the fight

In a quiet corner of the Ecuadorian Andes, a chorus...

Every year on April 22, Earth Day asks us to pause and think about the planet. We plant trees, clean beaches, and post nature pictures with hopeful captions. But the truth is that one day of action cannot match the daily toll our lifestyles place on the environment. Building a green life requires steady effort, not just symbolic gestures.



The good news? We don't need grand gestures. Simple, science-backed habits, when practiced regularly, can help create a cleaner, healthier <a href="https://www.earth.com/news/astonishing-global-heat-in-january-2025-defied-climate-expectations/" target="_blank" rel="noreferrer noopener">Earth</a>.



Many people want to live more sustainably but feel unsure where to begin. Climate change, plastic pollution, and biodiversity loss seem too big to tackle. But change begins with consistency, not perfection. 



You don’t need to live off-grid or give up modern comforts. You only need to make conscious choices - ones that respect natural limits and future generations.



<h2 class="wp-block-heading" id="h-eat-less-meat-for-a-greener-life">Eat less meat for a greener life</h2>



<a href="https://www.sciencedirect.com/science/article/pii/S0308521X25000034" target="_blank" rel="noreferrer noopener">What we eat</a> affects more than our waistlines. Agriculture, especially livestock farming, consumes water, destroys forests, and releases greenhouse gases. 



Methane from cows is over 25 times more potent than carbon dioxide at trapping heat. Shifting away from heavy meat consumption can reduce your carbon footprint.



Even replacing a few meals a week with plant-based options can create measurable change. Think lentils instead of beef, tofu instead of chicken, or beans in your tacos. These swaps support not only climate goals but also heart health and resource conservation. 



Science shows that diet plays a direct role in emissions and and that dietary changes can help build a green life.



<h2 class="wp-block-heading" id="h-the-value-of-water-conservation">The value of water conservation</h2>



Water seems abundant, but it’s a limited and <a href="https://www.nature.com/articles/s41467-025-56517-2" target="_blank" rel="noreferrer noopener">unevenly distributed resource</a>. In the western U.S., prolonged droughts have made conservation efforts more urgent than ever. Climate change intensifies these patterns, affecting agriculture, power supply, and daily life.



Household habits can help. Fixing leaky faucets, turning off the tap while brushing teeth, and using low-flow showerheads save gallons daily. 



Small adjustments add up across millions of households. Conserving water protects ecosystems and helps ensure availability for future needs. You don't have to overhaul your plumbing - just be mindful of every drop.



<h2 class="wp-block-heading" id="h-waste-less-food-for-a-greener-life">Waste less food for a greener life</h2>



Every year, Americans throw away nearly 40 percent of the food they buy. That waste often ends up in landfills, where it breaks down without oxygen and produces methane. Reducing this waste is one of the easiest ways to lower your <a href="https://www.earth.com/news/green-environments-and-sidewalks-improve-heart-health/" target="_blank" rel="noreferrer noopener">environmental impact</a>.



Start by buying only what you need. Store perishables correctly and learn to use leftovers in new meals. Composting scraps instead of tossing them supports soil health and keeps waste out of landfills. 



Reducing food waste also saves money, reduces guilt, and respects the energy used to grow, ship, and prepare our meals.



<h2 class="wp-block-heading" id="h-cleaner-transportation-choices">Cleaner transportation choices</h2>



Our cars, buses, and planes run on fossil fuels. Each gallon of gasoline burned releases about 20 pounds (9 kilograms) of carbon dioxide.



Transportation now ranks as the largest source of greenhouse gas <a href="https://www.earth.com/news/urban-green-spaces-are-urgently-needed-across-the-global-south/" target="_blank" rel="noreferrer noopener">emissions</a> in the U.S. That means rethinking how we move from place to place can make a real difference.



Walking and cycling cut emissions to zero and support a healthier, greener life. Even taking public transit or carpooling lowers your daily carbon output. In urban areas, many cities now offer bike shares and improved bus systems.



Choosing these options - even once a week - reduces traffic congestion and air pollution. Sustainable travel doesn't mean sacrificing comfort. It means reimagining convenience with the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0195925524003548?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">planet</a> in mind.



<h2 class="wp-block-heading" id="h-use-less-energy-for-a-green-life">Use less energy for a green life</h2>



Many homes still rely on energy <a href="https://www.earth.com/news/is-methanol-the-next-green-power-player-clean-energy-source/" target="_blank" rel="noreferrer noopener">sources</a> that pollute. Coal, natural gas, and oil-powered plants fuel much of our electricity grid. Using less electricity means demanding less from these sources.



Start simple. Replace incandescent bulbs with LED alternatives. Unplug appliances that stay on standby power. Invest in energy-efficient refrigerators, air conditioners, and washing machines. 



Smart thermostats can reduce heating and cooling needs by adapting to your habits. These changes lower emissions and utility bills without affecting comfort or convenience.



<h2 class="wp-block-heading" id="h-say-no-to-single-use-plastics">Say no to single-use plastics</h2>



Plastic was once a miracle material - light, cheap, and durable. Today, it’s a global problem. 



Single-use plastics fill landfills, clog oceans, and harm wildlife. They never fully break down. Instead, they fragment into microplastics that pollute <a href="https://www.earth.com/news/world-water-day-2025-preserving-glaciers-protecting-our-future/" target="_blank" rel="noreferrer noopener">water</a>, air, and even human bloodstreams.



Switching to reusables is a straightforward step toward a green life. Cloth shopping bags, metal water bottles, and glass containers reduce waste and last for years. Carry your own straw or cutlery if you eat on the go. 



Avoiding single-use items sends a message: convenience should not come at nature’s expense.



<h2 class="wp-block-heading" id="h-support-local-think-seasonal">Support local, think seasonal</h2>



Where your goods come from matters. Food, clothing, and household items often travel thousands of miles before reaching your home. 



This transportation adds to carbon emissions and energy use. Supporting local producers cuts that distance and encourages sustainable farming and business practices.



Farmers’ markets and community-supported agriculture programs connect you directly to the source. Seasonal produce tastes better, requires less refrigeration, and often uses fewer pesticides. 



When you buy local, you reduce emissions and strengthen your community’s economy. You also gain a better understanding of the true cost of production.



<h2 class="wp-block-heading" id="h-small-actions-can-build-a-green-life">Small actions can build a green life</h2>



Big environmental issues feel overwhelming, but personal habits can shift the tide. 



Each eco-friendly decision you make sets an example for others. Friends, children, neighbors - they notice. The power of collective action lies in its quiet repetition.



Make Earth Day more than a holiday. Let it be a prompt - a reminder that the planet’s future lives in our routines. Small choices, multiplied daily and shared widely, build resilience into our world.



Sustainability isn’t far away. It’s in your kitchen, daily commute, wardrobe, water bill, and every choice that shapes a green life.

​Earth Day every day: Simple tips for a greener life

Every year on April 22, Earth Day asks us to...

On Earth Day and every day, a powerful shift is unfolding around the world. It's a rising movement where people are rethinking their relationship with the planet. It’s no longer just about sustainability - it’s about regeneration, justice, and resilience.



The planet has endured for billions of years - through fire, ice, and <a href="https://www.earth.com/news/extinction-crisis-entire-branches-of-earths-tree-of-life-are-vanishing/" target="_blank" rel="noreferrer noopener">mass extinctions</a>. It will continue to turn with or without us. But what’s at stake now is the world as we know it: the fragile balance of nature that we depend on for clean air, fresh water, food, and health.



When we speak of “saving the planet,” what we’re truly saying is that we need to save the conditions that allow life to survive.&nbsp;



<h2 class="wp-block-heading" id="h-lifelines-for-our-children">Lifelines for our children</h2>



Recycling, rewilding, reducing emissions - these aren’t just noble acts; they are lifelines. They are how we secure a future for our children.



Each plastic bottle we keep out of the <a href="https://www.earth.com/news/ocean-plastic-pollution-has-become-a-global-crisis/" target="_blank" rel="noreferrer noopener">ocean</a>, each acre of land we return to nature, each ton of carbon we prevent from entering the sky - these choices may seem small on their own, but they are part of a much greater promise.



They are the thoughtful threads we weave into a safety net for future generations.&nbsp;



<h2 class="wp-block-heading" id="h-love-in-action">Love in action</h2>



Recycling means less waste choking our seas and less energy drained from a tired planet. Rewilding breathes life back into barren landscapes, inviting back the birds, the bees, and the balance.&nbsp;



Reducing emissions can slow the heating of our planet and helps restore the rhythm of seasons, rains, and harvests.



When we take these steps, we are saying to our children: “You matter. Your future matters. This Earth will still bloom for you.”



This is even bigger than sustainability - it’s love in action.



<h2 class="wp-block-heading" id="h-the-cost-of-climate-inaction-nbsp">The cost of climate inaction&nbsp;</h2>



The cost of climate inaction is already unfolding around us - not as some distant warning, but as a present reality.&nbsp;



Intense wildfires, storms that flatten entire communities, droughts that empty reservoirs and wither crops are no longer anomalies. They are the echoes of a <a href="https://www.earth.com/news/limiting-global-warming-to-1-5-degrees-celsius-would-save-billions-of-lives/" target="_blank" rel="noreferrer noopener">warming world</a>, growing louder each year.



The most devastating toll is not measured in dollars or degrees. It’s measured in the futures we are putting at risk. For every year we delay action, the window narrows for our children to inherit a livable world.&nbsp;



Rising seas threaten to swallow the coastlines where memories are made. Polluted air burdens young lungs before they ever have a chance to grow strong. Food security, once taken for granted, is strained under the pressure of extreme weather.&nbsp;



Diseases spread where they once couldn’t. Homes become uninhabitable. The safety net we imagined was there begins to fray.



And yet, perhaps the heaviest cost is the legacy we are leaving behind - not just a <a href="https://www.earth.com/news/climate-experts-predict-global-warming-will-far-exceed-paris-goals/" target="_blank" rel="noreferrer noopener">planet under stress</a>, but a message that convenience mattered more than courage, that short-term gain outranked long-term care.&nbsp;



<h2 class="wp-block-heading" id="h-cultural-wisdom-and-indigenous-knowledge">Cultural wisdom and Indigenous knowledge</h2>



Long before the language of carbon footprints and climate models, there were people who understood the rhythms of the Earth not through data, but through deep connection with nature.&nbsp;



Indigenous communities around the world have spent generations learning from the land. They have read the skies and listened to the forests. They learned when to plant, when to harvest, and when to let the earth rest. 



Indigenous knowledge is not a relic of the past; it is a living library.



In many cases, Indigenous knowledge has helped protect biodiversity and preserve ecosystems where modern conservation efforts have struggled. And yet, for too long, it has been ignored, dismissed, or suppressed.&nbsp;



Now, as the planet suffers from industrial excess, there is a growing recognition that the wisdom we need may not be new - it may be ancient.



<h2 class="wp-block-heading" id="h-living-lighter-with-more-meaning">Living lighter, with more meaning</h2>



When we look to ancient wisdom for guidance, we can see our everyday choices through new eyes.



Living lighter is a way of moving through the world that leaves a gentler footprint and a stronger legacy. This approach to life is not about giving things up - it’s about gaining a deeper sense of what truly matters.&nbsp;



Living lighter can take many simple, meaningful forms. It could be choosing local foods or growing herbs on a windowsill. It might be carrying a reusable bag or coffee cup - not out of habit, but out of care.&nbsp;



Every time we choose to walk instead of drive, we are helping to heal the damage we have caused.&nbsp;



<h2 class="wp-block-heading" id="h-the-power-of-collective-action">The power of collective action</h2>



No single person can carry the weight of the world - but many people together can lift it.&nbsp;



Communities are turning rooftops into thriving <a href="https://www.earth.com/news/urban-gardens-promote-biodiversity/" target="_blank" rel="noreferrer noopener">gardens</a>. Towns are breathing life back into long-lost rivers, restoring the flow of nature through their streets.



This is the spirit of Earth Day - a reminder that we are not separate stories, but one rising chorus. The future isn’t something we inherit; it’s something we build together - for our children and for all future generations.

Earth Day 2025: What we’re really fighting for

On Earth Day and every day, a powerful shift is...

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.

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 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.



"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.



"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."

Today's Video of the Day 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.



"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.



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.
