Today's Image of the Day from the European Space Agency features a pair of interacting spiral galaxies known as the Antennae Galaxies. They are located approximately 45 million light-years away in the constellation Corvus.&nbsp;



<h2 class="wp-block-heading" id="h-antennae-galaxies-in-a-deadly-embrace">Antennae Galaxies in a deadly embrace </h2>



“The NASA/ESA Hubble Space Telescope has snapped the best ever image of the Antennae Galaxies. Hubble has released images of these stunning galaxies twice before, once using observations from its Wide Field and Planetary Camera 2 (WFPC2) in 1997, and again in 2006 from the Advanced Camera for Surveys (ACS),” noted <a href="https://esahubble.org/images/potw1345a/" target="_blank" rel="noreferrer noopener">ESA</a>.



“The galaxies - also known as NGC 4038 and NGC 4039 - are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another.”



According to ESA, the clash of the Antennae Galaxies is so violent that stars have been ripped from their host <a href="https://www.earth.com/news/galaxy-collision-2-million-mph-stephans-quintet-captured-unprecedented-detail/" target="_blank" rel="noreferrer noopener">galaxies</a> to form a streaming arc between the two.&nbsp;



The name "Antennae" comes from this long stream of stars and gas, which resembles insect antennae.



<h2 class="wp-block-heading" id="h-intense-bursts-of-star-formation-nbsp">Intense bursts of star formation&nbsp;</h2>



The collision has triggered intense bursts of star formation, making the Antennae Galaxies one of the nearest and most dramatic examples of a starburst galaxy.&nbsp;



Many of the newly formed stars are concentrated in massive star clusters, some of which are expected to evolve into globular clusters over millions of years.



“This new image of the Antennae Galaxies shows obvious signs of chaos. Clouds of gas are seen in bright pink and red, surrounding the bright flashes of blue star-forming regions - some of which are partially obscured by dark patches of dust,” explained ESA.



“The rate of star formation is so high that the Antennae Galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars.”&nbsp;



“This cannot last forever and neither can the separate galaxies; eventually the nuclei will coalesce, and the galaxies will begin their retirement together as one large elliptical galaxy.”



<h2 class="wp-block-heading" id="h-significance-of-the-antennae-galaxies">Significance of the Antennae Galaxies</h2>



The Antennae Galaxies are one of the most well-studied examples of galaxy collisions, offering insight into the processes that shape galaxies over time.



Astronomers study the Antennae Galaxies using a range of telescopes across different wavelengths, including visible light, infrared, and X-rays.&nbsp;



Observations in X-rays have revealed evidence of supernovae and <a href="https://www.earth.com/news/black-holes-may-talk-to-galaxies-through-energetic-winds/" target="_blank" rel="noreferrer noopener">black holes</a>, while infrared studies highlight regions of dust and star formation.&nbsp;



<h2 class="wp-block-heading" id="h-the-milky-way-s-collision-course-nbsp">The Milky Way's collision course&nbsp;</h2>



The Antennae Galaxies provide a glimpse into the future of our <a href="https://www.earth.com/news/uma3-u1-faintest-star-system-found-orbiting-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">Milky Way</a>, which is expected to eventually merge with the Andromeda Galaxy - our closest spiral galaxy neighbor.



The cosmic collision course of the Milky Way and Andromeda will reshape both galaxies over billions of years.&nbsp;



This event is expected to occur in about 4.5 billion years. Both galaxies are part of the Local Group, a cluster of galaxies bound together by gravity. Their mutual gravitational pull is drawing them closer at a speed of approximately 110 kilometers per second.



<h2 class="wp-block-heading" id="h-the-birth-of-an-elliptical-galaxy-nbsp">The birth of an elliptical galaxy&nbsp;</h2>



When the two galaxies collide, their individual stars will largely avoid direct collisions due to the vast distances between them. However, the gravitational forces involved will create dramatic effects.&nbsp;



These forces will distort the galaxies' <a href="https://www.earth.com/news/shapes-of-one-million-galaxies-hint-at-the-universes-origins/" target="_blank" rel="noreferrer noopener">shapes</a>, triggering intense bursts of star formation as gas clouds collide and compress. Over time, the galaxies will settle into a new, larger elliptical galaxy often referred to as "Milkomeda" or "Milkdromeda" by astronomers.



<h2 class="wp-block-heading" id="h-galaxy-merger-and-the-solar-system">Galaxy merger and the solar system</h2>



Despite the seemingly destructive nature of the collision, the solar system is unlikely to face direct harm. Our Sun may find itself flung into a new orbit within the merged galaxy or even cast into intergalactic space.&nbsp;



The merger will also significantly alter the night sky, with the Andromeda Galaxy becoming increasingly prominent before blending into the unified structure.



This event is part of the natural <a href="https://www.earth.com/news/galaxies-are-much-bigger-than-we-originally-believed-gas-clouds/" target="_blank" rel="noreferrer noopener">evolution of galaxies</a> and serves as a fascinating reminder of the dynamic and ever-changing nature of the universe. 



While the collision is still billions of years away, studying it helps astronomers understand galactic interactions and the long-term future of our cosmic neighborhood.

Violent clash of the Antennae Galaxies  

Today's Image of the Day from the European Space Agency...

Today's Image of the Day from NASA Earth Observatory features an astronaut photograph of Fayzabad, a culturally diverse city in the Kokcha River valley of Northern Afghanistan. The photo was captured as the International Space Station passed over central Asia.



Fayzabad is the capital of the Badakhshan Province. It is located in a mountainous part of northeastern Afghanistan at an elevation of about 4,000 feet.



“The city is situated along the Kokcha River, which flows northward within a deep river valley surrounded by the Hindu Kush Mountains and eventually discharges into the Amu Darya River,” noted NASA.



<h2 class="wp-block-heading" id="h-climate-of-fayzabad-nbsp">Climate of Fayzabad&nbsp;</h2>



The climate of Fayzabad varies from cold semi-arid to Mediterranean-influenced warm-summer humid continental, according to <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.



The summer months are warm, with average high temperatures ranging from 77 to 86 degrees Fahrenheit.&nbsp;



The winter months are cold, with average low temperatures often dropping below freezing - sometimes reaching as low as 14 degrees Fahrenheit.&nbsp;



The region receives moderate precipitation, mostly during the spring and winter. Snowfall is common in winter, adding to the picturesque landscape. 



<h2 class="wp-block-heading" id="h-fayzabad-culture">Fayzabad culture</h2>



Historically, Fayzabad has been a center of learning and culture, though its development has been hampered by years of conflict.&nbsp;



Despite these challenges, <a href="https://www.earth.com/news/humans-started-cumulative-culture-around-600000-years-ago/" target="_blank" rel="noreferrer noopener">culture</a> remains a vital component of the region, which is known for its traditional crafts including weaving and embroidery.



Cultural life in Fayzabad is influenced by its predominantly Tajik population, along with other ethnic groups such as Uzbeks and Hazaras. The local cuisine is a blend of traditional Afghan flavors, incorporating ingredients like rice, meat, and a variety of spices.



<h2 class="wp-block-heading" id="h-land-use-changes-nbsp">Land use changes&nbsp;</h2>



“This territory has experienced notable changes in its land use in recent decades, especially with commercial and administrative growth near the airport,” noted NASA.



“Among the changes: a new airstrip built west of the Kokcha River. However, mountains hem in the city and limit how much development is possible.”



“Despite these topographical barriers, some development has spread into hilly areas south of Fayzabad. Green vegetation is mostly confined to mountain valleys, stream channels, and the Kokcha River floodplain.”&nbsp;



“The Kokcha River meanders through the valley, providing a vital water resource for the region. Fields of predominantly wheat and rice cover much of the floodplain, though these flat areas are mixed with residential, industrial, and commercial activity as well.”



<h2 class="wp-block-heading" id="h-kokcha-river-nbsp">Kokcha River&nbsp;</h2>



The Kokcha River originates in the Hindu Kush mountains. It stretches approximately 360 kilometers before joining the Amu Darya, one of Central Asia's major <a href="https://www.earth.com/news/hypoxia-is-a-serious-problem-in-rivers-worldwide/" target="_blank" rel="noreferrer noopener">rivers</a>.&nbsp;



The Kokcha River traverses rugged terrain, providing vital irrigation for agriculture in the region and supporting local communities' livelihoods.&nbsp;The <a href="https://www.earth.com/news/what-amount-of-water-do-earths-rivers-hold/" target="_blank" rel="noreferrer noopener">river</a> basin features diverse landscapes that include mountainous areas and fertile valleys.&nbsp;



Throughout history, the Kokcha River has played a crucial role in the region's cultural and economic development, serving as a natural resource for the inhabitants and influencing settlement patterns.



<h2 class="wp-block-heading" id="h-northern-afghanistan">Northern Afghanistan </h2>



Northern Afghanistan is known for its diverse landscape, featuring fertile plains, rugged mountains, and strategic rivers such as the Amu Darya. 



Historically, northern Afghanistan has been an important cultural and trade center. The city of Balkh, often referred to as "the mother of cities," is a hub of early civilization and a major stop on the Silk Road.



Northern Afghanistan has experienced periods of relative stability compared to the rest of the country, though it has also seen conflict - particularly during the Soviet invasion, the civil war of the 1990s, and the more recent Taliban resurgence.



The region's economy traditionally revolves around agriculture. Wheat, cotton, and fruits are key crops. In addition, there are vast mineral resources, although instability has hindered their full exploitation. 



<h2 class="wp-block-heading" id="h-wildlife-of-northern-afghanistan">Wildlife of Northern Afghanistan </h2>



In mountainous regions of Northern Afghanistan, such as the Hindu Kush, you can find species like the elusive snow leopard, which is well-adapted to the rugged terrain. 



Other mountain-dwelling animals include the Asiatic black bear and the Siberian ibex, both of which thrive in the high-altitude environments.



The plains and valleys are home to various species of antelope, such as the goitered gazelle, as well as foxes, wolves, and smaller mammals like hares. 



Birdlife is also abundant, with species ranging from eagles and vultures in the mountains to waterfowl along rivers and wetlands. The region’s rivers and lakes, though under environmental pressure, support fish species and amphibians.



However, many of these species are under threat. Decades of war and instability have impacted conservation efforts, with illegal hunting and habitat destruction taking a toll on populations. 



Some areas, such as the Wakhan Corridor in the northeast, remain relatively untouched and serve as crucial refuges for wildlife where rare species like the Marco Polo sheep still roam. These havens are increasingly important for conservation efforts in the region.

Fayzabad and the Kokcha River valley 

Today's Image of the Day from NASA Earth Observatory features...

Today's Image of the Day from NASA features the spiral galaxy NGC 2566, which is located 76 million light-years away in the constellation Puppis. The image was captured by the NASA/ESA Hubble Space Telescope.



“A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disk takes on an almond shape, giving the galaxy the appearance of a cosmic eye,” said <a href="https://phys.org/news/2024-12-hubble-spies-spiral-galaxy-ngc.html" target="_blank" rel="noreferrer noopener">NASA</a>.



“As NGC 2566 appears to gaze at us, astronomers gaze right back, using Hubble to survey the galaxy's star clusters and star-forming regions.”



<h2 class="wp-block-heading" id="h-complex-appearance-of-ngc-2566">Complex appearance of NGC 2566</h2>



NGC 2566 lies at a considerable distance from Earth, making it a challenging object for amateur astronomers to observe in detail without powerful telescopes.&nbsp;



It can be seen in the Southern Hemisphere sky and is better observed from locations with minimal <a href="https://www.earth.com/news/how-light-pollution-influences-interest-in-astronomy/" target="_blank" rel="noreferrer noopener">light pollution</a>.&nbsp;



The galaxy's arms are populated with young, bright stars, regions of active star formation, and interstellar gas and dust - giving it a dynamic and complex appearance.



<h2 class="wp-block-heading" id="h-measuring-the-ages-of-stars">Measuring the ages of stars</h2>



According to NASA, data from Hubble is especially valuable for studying stars that are just a few million years old. “These stars are bright at the ultraviolet and visible wavelengths to which Hubble is sensitive.”



“Using these data, researchers can measure the ages of NGC 2566's stars, which helps piece together the timeline of the galaxy's star formation and the exchange of gas between star-forming clouds and the stars themselves.”



<h2 class="wp-block-heading" id="h-star-formation-in-galaxies">Star formation in galaxies</h2>



Star formation in <a href="https://www.earth.com/news/shapes-of-one-million-galaxies-hint-at-the-universes-origins/" target="_blank" rel="noreferrer noopener">galaxies</a> is a fascinating and complex process that unfolds over millions of years. It begins in vast clouds of gas and dust, known as molecular clouds, which are often found in the spiral arms of galaxies or in regions of irregular or starburst galaxies.&nbsp;



These clouds provide the raw material for star formation, consisting primarily of hydrogen and helium, with trace amounts of heavier elements.



As the molecular clouds collapse under their own gravity, regions within them begin to condense and fragment, forming dense clumps. Within these clumps, protostars emerge. Their formation is driven by the gravitational pull drawing in surrounding gas. 



During this process, the gas heats up due to increasing pressure, eventually igniting nuclear fusion in the core, signaling the birth of a new star.



<h2 class="wp-block-heading" id="h-rate-of-star-formation-nbsp-across-galaxies">Rate of star formation&nbsp;across galaxies</h2>



The rate of star formation varies across galaxies is influenced by numerous factors. In spiral galaxies like the Milky Way, star formation is most active in the spiral arms, where density waves compress gas and dust, triggering the collapse of molecular clouds. 



In contrast, elliptical galaxies, which often have little cold gas and dust, typically exhibit low rates of star formation or none at all.



Starburst galaxies, on the other hand, experience episodes of exceptionally high star formation, often triggered by <a href="https://www.earth.com/news/webb-captures-a-galaxy-collision-with-a-radiant-smile/">galactic collisions</a> or interactions. 



These events can funnel large amounts of gas into central regions, leading to intense star-forming activity. However, such bursts are usually short-lived on cosmic timescales, exhausting the available gas quickly.



The environment within a galaxy also plays a significant role. Stellar winds and supernova explosions from existing stars can both inhibit and promote star formation. They may disperse gas, preventing further collapse, or compress nearby clouds, triggering new star formation.&nbsp;



Over time, as galaxies evolve, the availability of gas diminishes, leading to a gradual decline in star formation activity.



<h2 class="wp-block-heading" id="h-the-puppis-constellation-nbsp">The Puppis constellation&nbsp;</h2>



The Puppis constellation in the southern sky represents the stern of a ship. It was once part of a larger constellation known as Argo Navis, which depicted the mythical ship of Jason and the Argonauts. 



However, Argo Navis was later divided into three separate constellations: Puppis, Carina (the keel), and Vela (the sails). Puppis is the largest of these three and contains many notable celestial objects.



This constellation is home to several bright stars, including Naos (Zeta Puppis), a hot, massive star that emits intense ultraviolet radiation. Puppis also hosts a wide variety of deep-sky objects, such as open <a href="https://www.earth.com/news/stunning-star-clusters-captured-in-the-extreme-outskirts-of-the-milky-way/" target="_blank" rel="noreferrer noopener">star clusters</a> and nebulae. 



Among these, Messier 46 and Messier 47 stand out. Both are beautiful star clusters that are visible through binoculars or small telescopes. The region is dense with stars because it lies along the <a href="https://www.earth.com/news/milky-way-collision-may-change-everything-we-know-about-our-galaxy/" target="_blank" rel="noreferrer noopener">Milky Way</a>, making it a prime area for stargazing and astrophotography.

NGC 2566: A cosmic eye in the Puppis constellation

Today's Image of the Day from NASA features the spiral...

Today's Image of the Day from NASA Earth Observatory features Tropical Cyclone Sean, which brought record-breaking rainfall to the Pilbara region of Western Australia.



“On January 17, 2025, a tropical low formed over the Indian Ocean off Western Australia. By January 19, the storm had strengthened into Tropical Cyclone Sean - the second tropical cyclone of Australia’s 2024–2025 season,” noted <a href="https://earthobservatory.nasa.gov/images/153852/tropical-cyclone-sean-lashes-western-australia" target="_blank" rel="noreferrer noopener">NASA</a>.



“The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite acquired this image at about 10 a.m. local time (02:00 Universal Time) on January 20, 2025. Later that afternoon, the cyclone had reached its peak strength as a Category 4 storm.”



<h2 class="wp-block-heading" id="h-impacts-of-tropical-cyclone-sean-nbsp">Impacts of Tropical Cyclone Sean&nbsp;</h2>



Despite not making landfall, Sean's proximity to the coast brought record-breaking <a href="https://www.earth.com/news/rainfall-is-increasingly-unpredictable-due-to-climate-change/" target="_blank" rel="noreferrer noopener">rainfall</a> and strong winds to the Pilbara region. Karratha experienced its heaviest recorded daily rainfall of 10.8 inches in a 24-hour period. 



According to NASA, the storm flooded roads and homes, damaged power infrastructure, and prompted the closure of several ports.&nbsp;



“However, the storm also brought some relief from hot and humid conditions, according to news reports. Looking ahead, the abundant water could aid cattle station managers, allowing them to return their animals to grazing," noted NASA.



<h2 class="wp-block-heading" id="h-australia-s-tropical-cyclone-season">Australia's tropical cyclone season</h2>



Australia's tropical cyclone season typically peaks from November to April, coinciding with the warmer months in the Southern Hemisphere. This period is characterized by increased atmospheric instability and warm <a href="https://www.earth.com/news/humans-are-substantially-changing-the-seasons-of-the-ocean/" target="_blank" rel="noreferrer noopener">sea surface temperatures</a> - both of which are essential for cyclone formation. 



The region includes the waters surrounding northern Australia, encompassing the Indian Ocean, Coral Sea, and the Timor Sea.



Cyclones during this season can vary in intensity, ranging from low-category systems that bring heavy rainfall and minor winds to severe storms with destructive winds, storm surges, and extensive flooding.&nbsp;



The northern regions of Western Australia, the Northern Territory, and Queensland are most affected, with the Pilbara Coast being particularly vulnerable.



<h2 class="wp-block-heading" id="h-cyclone-impacts-in-australia-nbsp">Cyclone impacts in Australia&nbsp;</h2>



The impacts of these cyclones are diverse. Coastal areas often face significant storm surges, where sea levels rise and flood low-lying areas.&nbsp;



Cyclones can lead to widespread <a href="https://www.earth.com/news/can-we-outrun-the-flood-risks-of-climate-change/" target="_blank" rel="noreferrer noopener">flooding</a>, particularly when systems move slowly or interact with other weather patterns. Wind damage to infrastructure, homes, and vegetation is also a common concern. 



Cyclones provide much-needed rainfall to some areas, replenishing water supplies and sustaining ecosystems, but they can also cause severe disruptions to communities and industries, such as agriculture and mining.



<h2 class="wp-block-heading" id="h-monitoring-cyclone-activity">Monitoring cyclone activity</h2>



Australia uses advanced monitoring and forecasting systems to track cyclones, issuing timely warnings through the Bureau of Meteorology. These systems are vital for mitigating risks and aiding in disaster preparedness.&nbsp;



Community awareness campaigns and evacuation plans further help to minimize the loss of life and property during cyclone events.



Climate patterns such as La Niña and El Niño also influence cyclone activity. La Niña years typically bring more frequent and intense cyclones due to warmer waters around northern Australia, while El Niño years may suppress cyclone development.&nbsp;



Australia's preparedness for cyclones is supported by resilient building codes, emergency management practices, and community education. However, the increasing complexity of <a href="https://www.earth.com/news/cities-experience-more-rainfall-than-surrounding-areas/" target="_blank" rel="noreferrer noopener">urbanization</a> and environmental challenges requires ongoing adaptation to reduce the vulnerability of affected regions.



<h2 class="wp-block-heading" id="h-climate-change-and-cyclones">Climate change and cyclones</h2>



Recent research suggests that climate change could alter the dynamics of cyclone activity, potentially increasing the intensity of these storms even as their overall frequency may decline. This trend is primarily attributed to the <a href="https://www.earth.com/news/pacific-ocean-temperatures-highest-in-650-years-greatly-harming-coral-reefs/" target="_blank" rel="noreferrer noopener">warming of ocean waters</a>, which provides more energy to fuel cyclones. 



Warmer sea surface temperatures can lead to more moisture in the atmosphere, intensifying the rainfall associated with these storms and amplifying their destructive potential. In addition, higher ocean heat content can result in stronger wind speeds, making cyclones more severe and capable of causing extensive damage to coastal and inland areas.



Furthermore, shifts in atmospheric circulation patterns driven by climate change could influence the regions where cyclones form and make landfall. 



For example, some studies predict that the tropics may see a slight contraction, pushing cyclone activity closer to subtropical regions. This shift could expose new areas to significant storm risks, particularly those less equipped to handle such events.&nbsp;

Tropical Cyclone Sean brings record rainfall to Australia 

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.

Lake Maracaibo: The lightning capital of the world

Today's Image of the Day from the European Space Agency features an incredible image of the Crab Nebula in bright neon colors. 



“The unusual image was produced by combining data from telescopes spanning nearly the entire electromagnetic spectrum, from radio waves to X-rays,” noted <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.&nbsp;



Colored in red, the Karl G. Jansky Very Large Array (VLA) provided information about the nebula gathered in the radio regime.



NASA’s Spitzer Space Telescope took infrared images, which appear yellow, while the NASA/ESA <a href="https://www.earth.com/news/hubble-captures-another-cosmic-masterpiece-in-galaxy-ngc-2217/" target="_blank" rel="noreferrer noopener">Hubble</a> Space Telescope provided images made in optical wavelengths, colored in green.&nbsp;



Blue colors represent ultraviolet observations made by ESA’s XMM-Newton telescope, and the purple colors are X-ray radiation data from NASA’s Chandra X-ray Observatory.



<h2 class="wp-block-heading" id="h-about-the-crab-nebula-nbsp">About the Crab Nebula&nbsp;</h2>



The Crab Nebula, located in the constellation Taurus, contains the remnants of a <a href="https://www.earth.com/news/supernova-explosions-could-damage-distant-planets/" target="_blank" rel="noreferrer noopener">supernova explosion</a> first observed on Earth in 1054 AD. This explosion was recorded by Chinese astronomers and possibly by Native American rock art.&nbsp;



The nebula spans about 11 light-years across and lies approximately 6,500 light-years away from Earth. It is one of the most <a href="https://www.earth.com/news/unraveling-the-mysterious-origins-of-the-crab-nebula/" target="_blank" rel="noreferrer noopener">studied objects</a> in the sky, largely due to its status as a bright and dynamic supernova remnant.&nbsp;



<h2 class="wp-block-heading" id="h-the-crab-pulsar">The Crab Pulsar</h2>



The Crab Nebula contains a pulsar at its center, which is a rapidly rotating <a href="https://www.earth.com/news/slow-spinning-neutron-star-completely-defies-our-expectations/" target="_blank" rel="noreferrer noopener">neutron star</a> that emits pulses of radiation. This pulsar, known as the Crab Pulsar, spins about 30 times per second and is a significant source of gamma rays and other forms of high-energy radiation.&nbsp;



The nebula itself is a complex structure of filaments and synchrotron radiation. The filaments are remnants of the original star's outer layers, while the synchrotron radiation emerges from electrons spiraling in the magnetic fields produced by the pulsar.



“Surrounding the pulsar lies a mix of material; some of it was originally expelled from the star before it went supernova, and the rest was ejected during the explosion itself,” explained ESA.&nbsp;



“Fast-moving winds of particles fly off from the neutron star, energizing the dust and gas around it. These different layers and intricacies of the nebula can be observed in all of the different wavelengths of light.”



<h2 class="wp-block-heading" id="h-crab-nebula-observations">Crab Nebula observations </h2>



Throughout its history, the Crab Nebula has provided critical insights into the processes of stellar death, the behavior of <a href="https://www.earth.com/news/pulsars-are-helping-astronomers-pinpoint-dark-matter/" target="_blank" rel="noreferrer noopener">pulsars</a>, and the mechanics of supernova remnants.&nbsp;



Its continuous observation has revealed changes over time, such as the expansion of its filaments and variations in its brightness, offering a dynamic laboratory for astrophysical studies.



Overall, the Crab Nebula is a highly energetic and object, providing valuable insights into the processes following a supernova explosion.



<h2 class="wp-block-heading" id="h-fascinating-facts-about-nebulae">Fascinating facts about nebulae</h2>



Nebulae are some of the most breathtaking and intriguing structures in the universe. They are vast clouds of gas and dust, often considered stellar nurseries where new stars are born. 



<h3 class="wp-block-heading" id="h-colors-of-nebulae">Colors of nebulae </h3>



One of the most fascinating aspects of nebulae is their ability to glow in different colors. This occurs because they either reflect the light of nearby stars or emit light due to the ionization of gases within them, particularly hydrogen. 



Some nebulae, like the famous Orion Nebula, are visible to the naked eye and serve as one of the nearest regions of active star formation.



<h3 class="wp-block-heading" id="h-planetary-nebulae">Planetary nebulae </h3>



Stars are born in dense regions of nebulae, and when they die, some will expel their outer layers, creating stunning structures known as planetary nebulae. The colorful clouds left behind can shine brightly for thousands of years. 



<h3 class="wp-block-heading" id="h-massive-size">Massive size</h3>



Another amazing fact is that some nebulae are so vast that light can take years to travel from one side to the other, stretching across hundreds of light-years.



<h3 class="wp-block-heading" id="h-star-remnants">Star remnants </h3>



Perhaps even more mind-boggling is the fact that nebulae are the remnants of previous generations of stars. Supernova explosions of massive stars can create these glowing clouds of gas and dust, seeding the cosmos with the elements necessary for the formation of new stars and planets.

Black-backed Jackal

The January blues aren't just a human struggle - our four-legged friends can feel them too. Dogs, much like humans, can experience post-holiday lows that leave them feeling out of sorts.



We're not talking about an episode of Blues Clues here, but rather a real phenomenon that affects many pets during this time of year.



According to new research conducted by the Guide Dogs organization, changes in routine and shorter days might be contributing to your dog's seasonal slump.



<h2 class="wp-block-heading" id="h-january-blues-in-dogs">January blues in dogs</h2>



Just as many of us feel a bit lethargic and down in January, our canine companions are no different. 



In fact, the survey found that about one in four dogs exhibit signs of lethargy and lack of energy. Furthermore, roughly one in seven dogs appear to show signs of <a href="https://www.earth.com/news/common-household-sounds-trigger-anxiety-in-dogs/" target="_blank" rel="noreferrer noopener">anxiety</a> or boredom. 



But what is bringing dogs down in January? The answer is surprisingly human-like: changes in daily routines, dark mornings, and the absence of their owners (after the festive season).



<h2 class="wp-block-heading" id="h-canine-emotions-mimic-humans">Canine emotions mimic humans</h2>



A staggering 94% of the surveyed owners agreed that their pets seemed to mirror their <a href="https://www.earth.com/news/dogs-can-feel-our-emotions-through-our-heart-rate/" target="_blank" rel="noreferrer noopener">emotions</a>.



"Dogs are incredibly attuned to their owners’ feelings, and when routines are disrupted or we feel low, it’s no surprise that they might reflect those changes," said Tim Stafford, director of canine affairs at Guide Dogs.



However, it’s worth mentioning that while <a href="https://www.earth.com/news/dogs-are-evolving-to-fit-the-modern-lives-of-humans/" target="_blank" rel="noreferrer noopener">dogs</a> may be receptive to our feelings, we might not be as good at recognizing theirs.



<h2 class="wp-block-heading" id="h-helping-your-dog-cope-with-the-blues">Helping your dog cope with the blues </h2>



January is undoubtedly a rough month for both dogs and their owners. With this in mind, it's important to pay extra attention to your dog’s behavior at this time.



"We know that dogs thrive on routine and consistency, so whilst January can be tough, by focusing on re-establishing structure and following our tips on exercise and stimulation, we can easily help our dogs (and ourselves) feel better," noted Stafford. 



<h2 class="wp-block-heading" id="h-january-s-impact-on-dog-owners">January's impact on dog owners</h2>



Did you know that more than half of dog owners feel the pressure of the dark days and cold weather of January? Approximately one-third are dealing with financial stress, while 39% struggle to get back into their routine.



Meanwhile, during January, many dog owners also observed noticeable changes in their pets' behavior. 



Lethargy was the most commonly reported issue - affecting 27% of dogs - while 15% of owners noted signs of anxiety in their furry friends. Additionally, 13% reported their dogs experiencing boredom.



Overall, 59% of owners acknowledged observing behavioral shifts in their pets during the post-holiday period.



<h2 class="wp-block-heading" id="h-how-to-boost-your-dog-s-mood">How to boost your dog's mood</h2>



The <a href="https://www.guidedog.org/" target="_blank" rel="noreferrer noopener">Guide Dogs organization</a> recommends maintaining regular routines around walks, playtimes, and meals. There's no denying that dogs feel secure when they know what to expect.



Engaging with your dog during walks, playing games, and teaching them new skills can spark joy and distract them from their January blues. 



On cold, dreary days, snuggling on the sofa with your furry friend can also help to reduce stress and forge a stronger bond.



<h2 class="wp-block-heading" id="h-disrupted-dog-routines">Disrupted dog routines</h2>



The January blues can impact how you care for your dog too. Around one in five people confessed that the dark mornings have delayed outings, disrupting their dog's routine.



With many dog owners returning to work, about 13% reported that their dogs are spending more time alone compared to the holiday season.



However, there is some light at the end of the tunnel. An uplifting 88% of owners agreed that walking their dog improved their mental well-being.



<h2 class="wp-block-heading" id="h-battling-the-january-blues">Battling the January blues</h2>



The survey concluded on a positive note, revealing that 45% of owners have resolved to lead a more active lifestyle this year. The respondents plan to use <a href="https://www.earth.com/news/dog-walking-improves-mobility-and-prevents-falls-in-older-adults/" target="_blank" rel="noreferrer noopener">dog walks</a> as an opportunity to improve their fitness.



So, as we muddle through January, know that you are not alone battling the blues. It seems even our furry friends are feeling it too. 



However, by spending more time with our dogs, we can lift their spirits while giving our own a much-needed boost as well.

Dogs suffer from the January blues, just like humans

The January blues aren't just a human struggle - our...

Understanding how birds think and process information has long been a mystery. Unlike mammals, birds do not leave behind preserved brains in fossils, making it difficult for scientists to study their cognitive abilities over time. 



However, a breakthrough study by evolutionary biologists in Australia and neuroscience researchers in Canada is now providing remarkable insights into avian intelligence.



By analyzing the structure of bird skulls using advanced digital technology, researchers at Flinders University in South Australia and the University of Lethbridge in Canada have developed a new way to study both extinct and living birds. 



The method involves creating digital "endocasts" from the cranial spaces inside bird skulls, allowing them to estimate brain size and shape with remarkable accuracy. 



This approach is giving scientists a clearer picture of bird cognition, intelligence, and evolutionary history without needing to physically examine brain tissue.



<h2 class="wp-block-heading" id="h-reconstructing-bird-brains">Reconstructing bird brains</h2>



The research, published in the journal&nbsp;Biology Letters, focuses on reconstructing <a href="https://www.earth.com/news/seagulls-birds-more-intelligent-than-believed/" target="_blank" rel="noreferrer noopener">bird</a> brain structures by analyzing the inside of their skulls.



By scanning dry museum skulls from long-dead birds, scientists have been able to extract surprisingly detailed information about their brains. This includes insights into the size of crucial brain regions responsible for intelligence and agility.



"This showed that the two correspond so closely that there is no need for the actual brain to estimate a bird's brain proportions," said study lead author and <a href="https://www.flinders.edu.au" target="_blank" rel="noreferrer noopener">Flinders University</a> PhD researcher Aubrey Keirnan.



Despite the term "bird brain" often being used as an insult, birds are known for their remarkable intelligence. Many bird species such as crows and parrots demonstrate problem-solving skills, tool use, and even self-awareness.



"The brains of birds are so large that they are practically a braincase with a beak," noted Keirnan.



This study sought to determine whether the imprint left by a bird's brain on its skull accurately reflects the proportions of two crucial parts of the brain: the forebrain, which is responsible for intelligence, and the cerebellum, which controls coordination and movement.



To test this, the researchers scanned the skulls of 136 bird <a href="https://www.earth.com/news/survival-of-the-smartest-chickadees-with-better-memory-live-longer/" target="_blank" rel="noreferrer noopener">species</a> and compared the results with either microscopic brain sections or existing literature data. 



By doing so, they were able to determine whether the volume of these critical brain regions matched the imprints left inside the skull.



<h2 class="wp-block-heading" id="h-unexpectedly-precise-correlation">Unexpectedly precise correlation</h2>



The results of the study surprised even the researchers. The correlation between brain volume and endocast surface area was almost one-to-one, indicating a highly reliable method for estimating brain proportions.



"We used computed microtomography to scan the <a href="https://www.earth.com/news/crows-hold-grudges-for-up-to-17-years/" target="_blank" rel="noreferrer noopener">bird</a> skulls. This allows us to digitally fill the brain cavity to get the brain's imprint, also called an endocast," explained Professor Vera Weisbecker from Flinders University.



The fact that endocasts so precisely reflect the shape of the brain means that scientists can now study the brains of rare and even extinct bird species without the need for preserved brain tissue. 



"This is excellent news because it allows us to gather insight into the neuroanatomy of elusive, rare, and even extinct species without ever even seeing their brains," said Weisbecker.



<h2 class="wp-block-heading" id="h-revolutionizing-bird-brain-research">Revolutionizing bird brain research</h2>



The ability to create digital endocasts marks a significant shift in how scientists study bird brains. In the past, researchers had to pour liquid latex into a skull cavity, wait for it to harden, and then break the skull to retrieve the endocast. This process was destructive and often impractical for studying rare or fragile specimens.



"Using non-destructive scanning not only allows us to create endocasts from the rarest of birds, it also produces digital files of the skulls and endocasts that can be shared with scientists and the public," explained Weisbecker.



With these digital models, researchers can now conduct large-scale comparative studies, track evolutionary trends, and even explore how different <a href="https://www.earth.com/news/crows-count-out-loud-just-like-toddlers/" target="_blank" rel="noreferrer noopener">bird species</a> developed their unique cognitive abilities. 



The ability to share digital endocasts worldwide also means that scientists can collaborate more easily and work with data from species that might be difficult to access in person.



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



One of the most exciting aspects of this research is its potential to shed light on the evolution of bird intelligence. 



By studying the brain structures of different bird species, researchers can gain a better understanding of how certain cognitive traits developed over time.



University of Lethbridge Professor Andrew Iwaniuk, who co-led the study, admits he was surprised by how accurately the endocasts reflected brain structures. 



"While most of the telencephalon (outer part of the forebrain) is visible from the outer surface, a substantial portion of the cerebellum is obscured by this region," said Professor Iwaniuk.



"Given that the degree of obscurity can vary between species, I did not expect a strong correlation between endocast surface area and brain volume across all <a href="https://www.earth.com/news/bigger-bird-brains-grow-at-the-expense-of-the-parents/" target="_blank" rel="noreferrer noopener">species</a>."



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



The study also has implications for conservation and research on endangered birds. Since many threatened species are difficult to study in the wild, being able to analyze skull structures from museum specimens could provide valuable insights into their cognitive abilities and behaviors.



Additionally, this research could offer clues about extinct species, including birds' closest prehistoric relatives: the dinosaurs. However, applying this method to dinosaurs remains uncertain. 



"For example, crocodiles are the closest living relatives of birds, but their brains look nothing like that of a bird - and their brains do not fill the braincase enough to be as informative," said Keirnan.



This suggests that while digital endocasts may help reconstruct the brains of extinct birds, they may not be as useful for studying dinosaur cognition.



<h2 class="wp-block-heading" id="h-future-of-avian-neuroscience">Future of avian neuroscience</h2>



This study marks a major step forward in avian neuroscience and evolutionary biology. By using advanced digital techniques, scientists can now explore the complexities of bird brains without relying on preserved brain tissue, opening up new possibilities for research.



As scanning technologies continue to improve, researchers may be able to refine their methods even further, potentially unlocking new insights into how birds process information, solve problems, and interact with their environments. 



The findings could also lead to a better understanding of the evolutionary pressures that shaped bird intelligence over millions of years.



Ultimately, this research demonstrates that birds are far more intelligent than the outdated stereotype of "bird brains" suggests. 



With new digital tools, scientists are now able to unlock the secrets hidden within bird skulls, providing a clearer picture of avian cognition and evolution.



As more species are studied, we may discover even more surprising connections between brain structure and intelligence in the animal kingdom.



The study is published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0596" target="_blank" rel="noreferrer noopener">Biology Letters</a>.

"Bird brain" study gives remarkable new insights into avian intelligence

Understanding how birds think and process information has long been...

A mysterious item from the inner workings of a cow has sparked a worldwide scramble. Hardened lumps of bile known as cattle gallstones have become so valuable that criminal rings on multiple continents have begun hunting them down.



Some stones can command over twice the price of gold, sparking tales of nighttime thefts and elaborate smuggling schemes.



<h2 class="wp-block-heading" id="h-why-cattle-gallstones-are-suddenly-important">Why cattle gallstones are suddenly important</h2>



The fascination with gallstones centers on their use in <a href="https://www.nccih.nih.gov/health/traditional-chinese-medicine-what-you-need-to-know" target="_blank" rel="noreferrer noopener">Chinese traditional medicine</a>, which is valued at around $60 billion annually, according to the World Health Organization (<a href="https://www.who.int/health-topics/traditional-complementary-and-integrative-medicine#tab=tab_1" target="_blank" rel="noreferrer noopener">WHO</a>).&nbsp;



<a href="https://africana.sdsu.edu/our-faculty/gomes" target="_blank" rel="noreferrer noopener">Dr. Daniela Gomes da Silva</a>, a researcher at <a href="https://www.international.unesp.br/" target="_blank" rel="noreferrer noopener">São Paulo State University</a>, says the intensifying appetite for these stones has pushed some producers to consider strange ideas, such as trying to induce gallstones in their herds.



<h2 class="wp-block-heading" id="h-understanding-cattle-gallstones-the-basics">Understanding cattle gallstones - the basics</h2>



Cattle gallstones are solid formations that develop in the gallbladder of cows, although they’re not as common as in humans. They usually form when there's an imbalance in the substances that make up bile, much like in humans. 



However, in cattle, gallstones are typically made up of calcium salts like calcium carbonate or calcium phosphate instead of cholesterol, which is more common in humans. 



This difference stems from cattle’s <a href="https://www.earth.com/news/how-ai-can-help-reduce-methane-emissions-from-cows/" target="_blank" rel="noreferrer noopener">unique digestive systems</a>, which are designed to process large amounts of plant material. 



Their high-fiber diets and the way their bodies handle bile contribute to the formation of these calcium-based stones.



When cattle develop gallstones, they might not always show obvious signs at first. However, if the stones block the bile ducts, cows can experience discomfort, reduced appetite, and <a href="https://www.earth.com/news/seaweed-supplements-reduce-methane-in-grazing-cattle/" target="_blank" rel="noreferrer noopener">digestive issues</a>. 



Farmers and veterinarians usually detect gallstones through ultrasound examinations or other imaging techniques if they suspect a problem. 



The fact that it's impossible to know if a cow has a gallstone without proper examination adds an entirely separate and sinister layer to this new global smuggling market.



<h2 class="wp-block-heading" id="h-high-price-and-a-hidden-black-market">High price and a hidden black market</h2>



These rust-colored nuggets can fetch more than $5,800 an ounce - twice as much as gold - in certain markets.



They are often dried, powdered, and then combined with other materials to form traditional pills that some believe can help treat serious <a href="https://www.earth.com/news/stem-cell-therapy-improves-brain-activity-after-stroke/" target="_blank" rel="noreferrer noopener">conditions like strokes</a>.



Because of the profits involved, a black market has developed. 



<a href="https://www.earth.com/news/saving-parrots-in-the-illegal-wildlife-trade-with-dna-technology/" target="_blank" rel="noreferrer noopener">Smugglers</a> are known to transport stones in hidden compartments to avoid taxes and police, and some producers are wary of armed theft by those who want a shortcut to these lucrative byproducts.



<h2 class="wp-block-heading" id="h-cattle-gallstones-and-stroke-recovery">Cattle gallstones and stroke recovery</h2>



The WHO <a href="https://www.emro.who.int/health-topics/stroke-cerebrovascular-accident/index.html" target="_blank" rel="noreferrer noopener">reports</a> that strokes are the leading cause of death in China. Traditional remedies that include gallstone powder are often promoted as a way to provide extra time for stroke patients.



One <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6548905/" target="_blank" rel="noreferrer noopener">study</a> from the <a href="https://www.hku.hk/" target="_blank" rel="noreferrer noopener">University of Hong Kong</a> found evidence that certain ingredients in popular “<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4281447/" target="_blank" rel="noreferrer noopener">Angong</a>” pills, which include cattle gallstone powder, may offer short-term protection for the brain in rats experiencing ischemic strokes. 



While these findings are still under investigation, this belief in gallstones’ protective qualities has added to their demand.



<h2 class="wp-block-heading" id="h-wildlife-controversies">Wildlife controversies</h2>



“The rapid growth of the TCM industry over the last few decades has exacerbated the pressure on endangered <a href="https://www.earth.com/news/world-wildlife-conservation-day-2024-saving-species-from-extinction/" target="_blank" rel="noreferrer noopener">wildlife</a> in Asia and beyond,” said the London-based <a href="https://eia-international.org/" target="_blank" rel="noreferrer noopener">Environmental Investigation Agency</a>. Some in the conservation community are concerned about the wider industry.&nbsp;



Although cattle gallstones themselves do not threaten wild species, the industry sometimes combines them with ingredients like rhino horn or <a href="https://www.earth.com/news/world-pangolin-day-project-launched-to-save-the-elusive-mammal/" target="_blank" rel="noreferrer noopener">pangolin scales</a> in certain remedies. That element has triggered alarm among groups working to curb illegal wildlife trafficking.



<h2 class="wp-block-heading" id="h-rising-demand-for-cattle-gallstones">Rising demand for cattle gallstones</h2>



Rising incomes and lifestyle changes in China have led to increased obesity, hypertension, and other conditions that are linked to <a href="https://www.heart.org/en/health-topics/consumer-healthcare/what-is-cardiovascular-disease" target="_blank" rel="noreferrer noopener">cardiovascular diseas</a><a href="https://www.earth.com/news/a-century-of-progress-in-the-fight-against-cardiovascular-disease/" target="_blank" rel="noreferrer noopener">e</a>. 



As a result, gallstones, once discarded by slaughterhouses, have become prized commodities.



Because some black-market dealers try to dodge strict regulations, gallstone shipments have been hidden in everyday items to <a href="https://www.earth.com/news/experts-are-using-forensic-science-to-fight-wildlife-trafficking/" target="_blank" rel="noreferrer noopener">avoid detection</a>.



Authorities have also encountered schemes where sugar or brick dust is injected or ground into the stones to inflate weight and boost profits.



<h2 class="wp-block-heading" id="h-modern-farming-methods-may-help">Modern farming methods may help</h2>



As Brazil becomes <a href="https://www.earth.com/news/ai-paves-the-way-for-climate-conscious-farming/" target="_blank" rel="noreferrer noopener">more efficient</a> in producing beef, some farmers shorten the lifespan of their cattle with optimized feeding routines. 



Da Silva explains that younger herds may yield better meat and fewer gallstones because there is less time for these lumps to form.



The irony is that while certain ranchers see gallstones as valuable gold nuggets, modern techniques that improve farm production may unintentionally reduce the presence of these costly stones. 



Still, unscrupulous players look to exploit any opportunity to get their hands on the product, even resorting to theft in some regions.



<h2 class="wp-block-heading" id="h-lingering-mysteries">Lingering mysteries</h2>



Scientists have yet to determine the precise reasons some cattle develop gallstones. Da Silva notes that older animals with more time on pasture are more prone to this condition.



However, it remains unclear how diet, genetics, and stress might play a role. Rumors occasionally spread of stones the size of a football, but these stories are rarely supported by credible evidence.



Experts caution producers not to chase unrealistic <a href="https://www.earth.com/news/world-elephant-day-2024-saving-the-gentle-giants/" target="_blank" rel="noreferrer noopener">legends</a>, warning that the gallstone frenzy can lead to costly risks, including robberies and legal troubles if regulations are ignored.



<h2 class="wp-block-heading" id="h-more-regulations-needed">More regulations needed</h2>



Strict enforcement and improved oversight may push more of the market into legal channels. Some industry analysts believe that, if gallstones continue to command a price above that of gold, more players will be tempted to enter the trade, thus fueling both opportunities and criminal activities.



Meanwhile, many medical professionals maintain that though traditional solutions may offer support, they should be one facet of a well-rounded approach to healthcare.&nbsp;



Despite the high prices and dramatic tales of smuggling, many in Brazil’s farming regions remain content to focus on milk and meat production. For them, cattle gallstones are a novelty - albeit a very expensive one.

Cattle gallstones, insanely valuable, are the new 'must-have' item in global smuggling rings

A mysterious item from the inner workings of a cow...

Most people are left confounded and flummoxed when presented with the most basic concepts of quantum mechanics. That's because they make no sense to any rational mind, so please don't take this statement as any type of slight. 



This is especially true when discussing something called "superposition" - where a particle can <a href="https://www.earth.com/news/quantum-entanglement-a-simple-way-to-grasp-this-impossible-concept-carl-kocher/" target="_blank" rel="noreferrer noopener">exist in multiple states</a> at the same time until someone actually measures it.



One of the most memorable thought experiments used to explain superposition is through the story of Schrödinger’s cat, which paints a picture of a hypothetical feline that is simultaneously alive and dead inside a box. 



When someone opens the box to observe the cat, the superposition is broken, and the cat definitively becomes one or the other: alive or dead.



<h2 class="wp-block-heading" id="h-schrodinger-s-cat-explains-quantum-strangeness">Schrödinger’s cat explains quantum strangeness</h2>



Of course, we never encounter boxes containing real animals in that type of bizarre dual state, yet researchers continually explore and test superpositions of much smaller particles. 



They do this for many reasons, but for the purposes of this research, a team of scientists focused on particle superposition because they believe it holds the secret to error-free <a href="https://www.earth.com/news/google-record-shattering-quantum-ai-chip-accesses-parallel-universes/" target="_blank" rel="noreferrer noopener">quantum computing</a>.



Quantum computers display processing <a href="https://www.cambridge.org/highereducation/books/quantum-computation-and-quantum-information/01E10196D0A682A6AEFFEA52D53BE9AE#overview" target="_blank" rel="noreferrer noopener">power</a> that monumentally eclipses anything that modern traditional computers or supercomputers can manage.



<a href="https://www.unsw.edu.au/staff/andrea-morello" target="_blank" rel="noreferrer noopener">Andrea Morello</a> from the University of New South Wales (<a href="https://www.unsw.edu.au/" target="_blank" rel="noreferrer noopener">UNSW</a>) has been at the forefront of turning these quantum properties into a secure and efficient way to store and process information.

Antimony is no ordinary atom. It has a nuclear spin with <a href="https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.5.033105" target="_blank" rel="noreferrer noopener">eight possible directions</a>, unlike simpler two-state systems called qubits.



That larger range protects the encoded data from sudden changes that would normally disrupt more fragile qubits.



A typical qubit can flip if anything nudges it, and one flip may turn a zero into a one, foiling any crucial calculation. The antimony approach helps avoid that vulnerability.



“As the proverb goes, a cat has nine lives. One little scratch is not enough to kill it,” says Xi Yu.



Each small error leaves most of the data intact, making it easier to notice and fix any trouble before it gets worse.



<h2 class="wp-block-heading" id="h-schrodinger-s-cat-inside-a-silicon-chip">Schrödinger’s cat inside a silicon chip</h2>



<a href="https://www.unsw.edu.au/staff/danni-holmes" target="_blank" rel="noreferrer noopener">Dr. Danielle Holmes</a> at UNSW built a silicon chip that can hold this single antimony atom. It grants full control over the spin state, and it is fashioned with the same material found in typical consumer electronics.



This opens the door for large-scale production methods that already exist. 



The prospect of connecting many atoms on a chip may allow <a href="https://www.sciencedirect.com/topics/materials-science/quantum-device" target="_blank" rel="noreferrer noopener">quantum devices</a> to be assembled using machinery that has served the regular semiconductor industry for decades.



<h2 class="wp-block-heading" id="h-error-correction-with-quantum-cats">Error correction with quantum cats</h2>



“A single, or even a few errors, do not immediately scramble the information,” says Morello, a professor at UNSW. <a href="https://www.earth.com/news/quantum-teleportation-of-logical-qubits-performed-for-the-first-time/" target="_blank" rel="noreferrer noopener">Quantum error correction</a> is a central challenge, since even minute glitches can cascade and ruin complicated tasks. 



By using antimony’s expanded spin space, the design does not topple when faced with a small slip. That extra buffer slows down error accumulation, so there is a higher chance of fixing mistakes in time.



Each quantum bit, or <a href="https://www.earth.com/news/building-quantum-computers-just-got-easier-with-new-technique/" target="_blank" rel="noreferrer noopener">qubit</a>, remains stable under minor disturbances that would derail simpler systems. Once a disturbance shows up, the device can often preserve the right values.



This relieves some of the burden from correction algorithms. With fewer surprises to manage, researchers hope these extra-robust qubits will lead to larger, more complex quantum circuits that can solve problems outside the reach of standard computers.



<h2 class="wp-block-heading" id="h-next-steps-in-quantum-computing">Next steps in quantum computing</h2>



Scientists plan to refine their tools for spotting and fixing errors the moment they pop up. They aim to push reliability high enough for lengthy <a href="https://scienceexchange.caltech.edu/topics/quantum-science-explained/quantum-superposition" target="_blank" rel="noreferrer noopener">computing</a> tasks.



Morello notes that this “Schrödinger’s cat” analogy shows how quantum systems can be both delicate and sturdy. 



By improving this technology, the team hopes to overcome one of the toughest hurdles to a fully fledged quantum computer.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



Quantum machines could support <a href="https://www.earth.com/news/code-breaking-encryption-quantum-computers-takes-big-step-closer-to-becoming-reality/" target="_blank" rel="noreferrer noopener">safer cryptography</a>, simulate large-scale phenomena, and sift through colossal data sets.



Engineers foresee a hybrid model where single-atom components work alongside today’s circuits, taking advantage of industrial processes that are already in place.



Though it may take time to perfect, early results suggest these unusual, cat-like states might boost the resilience of <a href="https://www.earth.com/news/quantum-computer-can-instantly-execute-a-task-that-would-normally-take-47-years/" target="_blank" rel="noreferrer noopener">quantum hardware</a>, and pave the way for a new era of computing.



<h2 class="wp-block-heading" id="h-rewriting-quantum-rules">Rewriting quantum rules</h2>



Teams worldwide keep testing different spins and elements, hunting for ways to control errors without overloading hardware resources. <a href="https://www.nature.com/articles/s41467-024-45368-y" target="_blank" rel="noreferrer noopener">High-dimensional nuclear spins </a>may be a vital stepping stone in this pursuit.



By letting these spins act like sturdy bits, researchers cut down the complicated fixes usually required. The hope is that robust qudit-based strategies will open the door to leaner and more powerful <a href="https://www.earth.com/news/quantum-computer-can-instantly-execute-a-task-that-would-normally-take-47-years/" target="_blank" rel="noreferrer noopener">quantum</a> machines.



Experts from UNSW Sydney, the <a href="https://www.unimelb.edu.au/" target="_blank" rel="noreferrer noopener">University of Melbourne</a>, <a href="https://www.sandia.gov/" target="_blank" rel="noreferrer noopener">Sandia National Laboratories</a>, <a href="https://www.nasa.gov/ames/" target="_blank" rel="noreferrer noopener">NASA Ames</a>, and the <a href="https://ucalgary.ca/" target="_blank" rel="noreferrer noopener">University of Calgary</a> joined forces for this research. They tackled materials growth, device engineering, and advanced theoretical modeling.



Together, they turned a classic thought experiment into a workable unit that might, someday soon, accelerate quantum technology to the point where we achieve error-free quantum computing at mass scale.

Schrödinger's cat successfully used in the real world, results could change the world

Most people are left confounded and flummoxed when presented with...

For the first time, researchers have measured the shape of an electron as it moves through a solid. This achievement could open a new way of looking at how electrons behave inside different materials. 



Their discovery highlights many effects that could be relevant to everything from <a href="https://www.earth.com/news/transmitting-quantum-information-using-electron-spin/" target="_blank" rel="noreferrer noopener">quantum information</a> science to electronics manufacturing.



Those findings come from a team led by physicist <a href="https://physics.mit.edu/faculty/riccardo-comin/" target="_blank" rel="noreferrer noopener">Riccardo Comin</a>, MIT’s Class of 1947 Career Development Associate Professor of Physics and leader of the work, in collaboration with other institutions. 



“We’ve essentially developed a blueprint for obtaining some completely new information that couldn’t be obtained before,” says Comin. His colleague and co-author, <a href="https://www.lassp.cornell.edu/people/mingu-kang" target="_blank" rel="noreferrer noopener">Mingu Kang</a>, performed much of this research at MIT before continuing at <a href="https://www.cornell.edu" target="_blank" rel="noreferrer noopener">Cornell University</a>.



<h2 class="wp-block-heading" id="h-new-angles-on-electron-shape">New angles on electron shape</h2>



Physicists have examined electrons for decades, but the wave-like aspect of these particles brings extra complexity. Electrons can be described not just as small points, but also as “wave functions.”&nbsp;



These wave functions look like shapes or surfaces in higher-dimensional spaces. Sometimes these shapes are relatively simple. Other times, they’re tangled and tricky to measure.&nbsp;



By using angle-resolved photoemission spectroscopy, or <a href="https://www.nature.com/articles/s43586-022-00133-7" target="_blank" rel="noreferrer noopener">ARPES</a>, the team recorded details about how electrons behaved as light hit them. 



ARPES helped them pin down a previously elusive property of electrons that holds the key to better understanding their geometry.



<h2 class="wp-block-heading" id="h-why-electron-shape-matters">Why electron shape matters</h2>



In usual settings, we talk about an electron’s energy or velocity. Those are familiar concepts. Geometry, on the other hand, points to the patterns or forms that electron waves can take when arranged in a solid.&nbsp;



<a href="https://www.earth.com/news/graviton-like-particle-observed-in-quantum-material-for-the-first-time/" target="_blank" rel="noreferrer noopener">Quantum geometry</a> affects how these particles interact, pair up, and even give rise to unusual behaviors. One example is superconductivity, where electrons zip along a material without resistance. 



Another is when electrons form orderly patterns, a bit like a collection of synchronized dancers. Observing geometry could help scientists design new materials with novel electronic traits.



<h2 class="wp-block-heading" id="h-the-kagome-connection">The kagome connection</h2>



The team measured this geometric effect in a class of materials called <a href="https://www.bnl.gov/newsroom/news.php?a=221687" target="_blank" rel="noreferrer noopener">kagome metals</a>. Kagome metals are named for a repeating pattern of atoms that resembles a series of interlocking triangles. This lattice structure can influence how electrons navigate and share energy.&nbsp;



Physicists have long found kagome metals interesting because they host special behaviors that aren’t common in many other materials. 



Observing the geometry inside them could explain why electrons in these metals sometimes align in peculiar ways that set off advanced superconductivity or other strange effects.



<h2 class="wp-block-heading" id="h-arpes-and-quantum-shapes">ARPES and quantum shapes</h2>



During ARPES experiments, researchers shine a beam of photons on a crystal. The light pushes <a href="https://www.earth.com/news/watching-electrons-move-1-quintillionth-of-second-attoseconds-attomicroscopy/" target="_blank" rel="noreferrer noopener">electrons</a> out of the material, allowing scientists to measure those electrons’ angles and spins. 



By gathering that data, they reconstruct how electrons inside the crystal are moving and what shapes they form. 



This method is demanding because it requires intricate equipment and specialized facilities. Yet it gives a unique window into what happens on distances smaller than a billionth of an inch.



<h2 class="wp-block-heading" id="h-applications-and-potential-benefits">Applications and potential benefits</h2>



A precise measurement of quantum geometry can lead to progress in areas that rely on electron control. <a href="https://www.earth.com/news/schrodingers-cat-put-into-silicon-chip-may-be-holy-grail-for-error-proof-quantum-computing/" target="_blank" rel="noreferrer noopener">Quantum computing</a>, for instance, depends on maintaining stable electronic states while performing computations. 



Researchers want materials that can reliably keep these states without unwanted disruptions. If scientists understand and possibly design the geometry of electrons, they might improve superconductors or even develop electronic devices that lose very little energy through heat. 



With energy efficiency becoming ever more critical, there’s real value in controlling electron flow on such tiny scales.



<h2 class="wp-block-heading" id="h-insights-from-global-teamwork">Insights from global teamwork</h2>



This <a href="https://mrl.mit.edu/index.php/articles/physicists_measure_quantum_geometry_for_the_first_time" target="_blank" rel="noreferrer noopener">study</a> was a partnership among institutions spanning different parts of the world. Collaborators brought together theoretical and experimental backgrounds. 



Their collective expertise made it possible to design, synthesize, and measure the electronic structure of a kagome metal. 



The pandemic forced some members to work remotely, but it also enabled other team members to take on new roles in labs that were partially shut down. 



That unexpected shift helped push the work forward and demonstrated how closely linked theory and experiment must be when tackling high-precision measurements.



<h2 class="wp-block-heading" id="h-one-electron-shape-many-possibilities">One electron shape, many possibilities</h2>



Quantum geometry is far richer than standard geometry we learn in everyday math. The shape of an electron’s <a href="https://www.earth.com/news/bose-einstein-condensate-bec-rare-form-quantum-matter-created-with-molecules/" target="_blank" rel="noreferrer noopener">wave function</a> isn’t like a typical circle or a neat sphere. It can take on forms that twist and loop in higher dimensions. 



Observing that shape in a real material confirms predictions that theorists have pursued for a long time. It means those theoretical constructs describing wave functions have real, measurable consequences. 



And now, there is a proven route to measure them, so future studies might target <a href="https://www.earth.com/news/edge-state-atoms-how-electrons-find-their-groove-in-frictionless-flow/" target="_blank" rel="noreferrer noopener">exotic materials</a> that exhibit other patterns or new behaviors.



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



Scientists plan to refine techniques like ARPES and adapt them to explore a range of materials. They hope to see how <a href="https://www.earth.com/news/graviton-like-particle-observed-in-quantum-material-for-the-first-time/" target="_blank" rel="noreferrer noopener">quantum geometry</a> influences conductivity, magnetism, and other conditions that matter for practical applications. 



Physicists also see promise in discovering how manipulating geometry might encourage electrons to swap their usual habits for more synchronized, cooperative behavior. 



That synchronization is important for technologies that rely on controlling multiple electrons at once, such as quantum sensors or memory elements.



Experts say these findings will likely inspire more ambitious experiments to uncover aspects of quantum geometry we haven’t been able to measure before.&nbsp;



With each new result, materials researchers step closer to engineering designs for the electronic components of tomorrow. The electron might be tiny, but it’s revealing secrets about shaping the future of technology.



The study is published in <a href="https://www.nature.com/articles/s41567-024-02678-8" target="_blank" rel="noreferrer noopener">Nature Physics</a>.

Shape of electrons is revealed for the first time through big advance in quantum physics

For the first time, researchers have measured the shape of...

Complex organisms, thousands of times smaller than a grain of sand, have the power to shape entire ecosystems and influence the Earth's climate. 



A recent study by researchers from Arizona State University (ASU) and the National University of the Peruvian Amazon reveals the existence of an unknown family of microbes thriving in the waterlogged, low-oxygen peatlands of Peru’s northwestern Amazon rainforest.



These tiny organisms play a crucial role in the carbon cycle, with the ability to either stabilize carbon for long-term storage or release it into the atmosphere as greenhouse gases, particularly carbon dioxide and methane.



The findings highlight the vital function of tropical peatlands as one of the world’s most significant carbon storage systems. The microbes within these ecosystems determine whether the peatlands remain vast carbon reservoirs or become sources of emissions that accelerate climate change. 



With human activity and climate shifts threatening their stability, the need to protect these delicate ecosystems has never been greater.



<h2 class="wp-block-heading" id="h-peatland-microbes-and-carbon-regulation">Peatland microbes and carbon regulation</h2>



Peatlands act as massive <a href="https://www.earth.com/news/global-warming-is-accelerating-beyond-control-as-co2-levels-rise/" target="_blank" rel="noreferrer noopener">carbon</a> vaults, storing immense amounts of organic material that has accumulated over thousands of years. This process occurs because the waterlogged conditions slow down decomposition, allowing peat to build up over time. 



In the Amazonian peatlands, newly discovered microbes belonging to the ancient Bathyarchaeia group regulate this process by breaking down carbon compounds. Their metabolic flexibility allows them to survive in extreme environments, including oxygen-poor conditions.



These microbes perform a dual function. Under stable conditions, they help store carbon, keeping it locked away in the peat and reducing the risks associated with climate change. 



However, environmental shifts, such as drought and <a href="https://www.earth.com/news/climate-extremes-in-2024-what-have-we-learned/" target="_blank" rel="noreferrer noopener">rising temperatures</a>, can activate these microbes in ways that lead to increased greenhouse gas emissions. If peatlands dry out or are disturbed, these organisms accelerate the release of stored carbon into the atmosphere, contributing to global warming.



<h2 class="wp-block-heading" id="h-fragile-balance-of-the-amazon-peatlands">Fragile balance of the Amazon peatlands</h2>



The microbes identified in the study are found in the&nbsp;Pastaza-Marañón Foreland Basin, one of the most extensive peatland regions in the northwestern Amazon rainforest of Peru. 



Spanning approximately&nbsp;100,000 square kilometers, this area contains vast stretches of flooded rainforest and swamps underlain by ancient peat. These peatlands store around&nbsp;3.1 billion tons of carbon, roughly double the carbon held in all the world’s forests combined.



Despite their immense importance, these peatlands face increasing threats from climate change and human activity. Shifts in rainfall patterns and rising temperatures can dry out the peat, changing the microbial activity and turning these carbon sinks into carbon sources. 



Deforestation, mining, and land-use changes further disrupt the natural equilibrium, accelerating the release of carbon dioxide and methane into the atmosphere.



<h2 class="wp-block-heading" id="h-significance-of-microbes-in-amazon-peatland">Significance of microbes in Amazon peatland</h2>



"The microbial universe of the Amazon peatlands is vast in space and time, has been hidden by their remote locations, and has been severely under-studied in their local and global contributions," said Hinsby Cadillo Quiroz, corresponding author of the study and researcher at <a href="https://www.asu.edu" target="_blank" rel="noreferrer noopener">ASU</a>’s Biodesign Swette Center for Environmental Biotechnology.



“Our work is finding incredible organisms adapted to this <a href="https://www.earth.com/news/climate-change-added-41-extra-days-of-dangerous-heat-in-2024/" target="_blank" rel="noreferrer noopener">environment</a>, and several of them provide unique and important services - from carbon stabilization or recycling to carbon monoxide detoxification and others."



<h2 class="wp-block-heading" id="h-the-climate-connection">The climate connection</h2>



For centuries, tropical peatlands have functioned as reliable carbon sinks, absorbing more carbon than they release. However, they are now at risk of becoming net carbon emitters due to <a href="https://www.earth.com/news/2024-confirmed-as-earths-hottest-year-in-recorded-history/" target="_blank" rel="noreferrer noopener">rising global temperatures</a> and changes in precipitation. 



When peatlands dry out, microbial activity shifts, leading to&nbsp;an increase in methane and carbon dioxide emissions. This process could drastically alter global carbon cycles and intensify climate change.



According to the study, continued human-caused disruptions could result in the release of 500 million tons of carbon by the end of the century - an amount equivalent to 5% of the world’s annual fossil fuel emissions. Such an outcome would significantly amplify global warming and accelerate environmental changes worldwide.



The researchers emphasize the urgent need for sustainable land management strategies to prevent these carbon-rich ecosystems from turning into major emission sources. Preventing deforestation, reducing drainage projects, and limiting mining activities in peatlands are crucial steps in preserving their role in climate regulation.



<h2 class="wp-block-heading" id="h-microbial-contributions-to-climate">Microbial contributions to climate</h2>



The discovery of these highly adaptable microbes provides new insights into how life persists in <a href="https://www.earth.com/news/we-are-in-a-race-against-time-to-save-our-food-supply-from-climate-change/" target="_blank" rel="noreferrer noopener">extreme environments</a> and how microorganisms influence global climate systems. 



These microbes consume carbon monoxide, a gas toxic to most life forms, and use it for energy, effectively reducing carbon toxicity in their surroundings. 



By breaking down organic carbon, the microbes generate hydrogen and carbon dioxide - which is then used by other microbes to produce methane. This interconnected microbial network plays a pivotal role in regulating the ecosystem’s overall carbon balance.



<h2 class="wp-block-heading" id="h-how-microbes-survive-in-amazon-peatland">How microbes survive in Amazon peatland</h2>



One of the most remarkable aspects of these microbes is their ability to survive in fluctuating oxygen levels. The Amazon rainforest undergoes seasonal shifts in water levels, creating an environment where oxygen availability changes throughout the year. 



These microbes have adapted to thrive under both oxygen-rich and oxygen-poor conditions, ensuring their survival in the dynamic Amazonian ecosystem.



However, as climate change alters rainfall patterns and human activities increase disturbances, the balance maintained by these microbes is at risk. 



Tracking shifts in temperature, precipitation, and ecosystem dynamics will be essential for predicting the future impact of microbial activity on climate stability.



<h2 class="wp-block-heading" id="h-path-forward-for-conservation">Path forward for conservation</h2>



As scientists uncover the microbial universe of Amazonian peatlands, they highlight the urgent need for conservation efforts. Protecting these ecosystems requires&nbsp;a combination of research, sustainable land management, and local engagement&nbsp;to ensure their long-term stability. 



The study demonstrates that the smallest organisms can have an outsized impact on global systems. When it comes to conservation, we must consider not only visible landscapes but also the microscopic life forms that sustain them.



This research, supported by the&nbsp;National Science Foundation, represents a significant step forward in understanding the crucial role of tropical peatlands in the global carbon cycle. As climate change continues to reshape our planet, the hidden ecosystems of the Amazon may hold key lessons for mitigating future environmental challenges.



Cadillo-Quiroz and his team plan to apply their findings to&nbsp;tropical peatland restoration. By deepening our understanding of microbial processes, they hope to develop strategies that enhance carbon sequestration and protect these vulnerable ecosystems from further degradation.



“Working to understand microbes and ecosystems in the lush and magnificent Amazon rainforest is the honor of my life, which I aim to use in the protection of this region in the fight against climate change,” said Cadillo-Quiroz.



The study is published in the journal <a href="https://journals.asm.org/doi/10.1128/spectrum.00387-24" target="_blank" rel="noreferrer noopener">Microbiology Spectrum</a>.

Tiny microbes in Amazon peatlands help balance the global climate

Complex organisms, thousands of times smaller than a grain of...

Artificial intelligence (AI) experts are abuzz about a new multimodal generative language model that may change how we think about proteins. 



Scientists have spent years searching for better ways to predict and design these tiny building blocks of life.



Yet, progress always felt like tiptoeing around a vast ocean. Now, a tool known as ESM3 has arrived. It is generating a fresh wave of excitement for anyone interested in uncovering uncharted protein varieties.



<h2 class="wp-block-heading" id="h-esm3-and-protein-science">ESM3 and protein science</h2>



<a href="https://www.science.org/doi/10.1126/science.ads0018" target="_blank" rel="noreferrer noopener">ESM3</a> can learn from protein sequences, structural information, and <a href="https://www.earth.com/news/how-life-begins-egg-sperm-and-a-covert-team-of-proteins/" target="_blank" rel="noreferrer noopener">functional annotations</a> at the same time, which broadens what it can “understand.” Previous models mostly looked at sequences alone.



This more robust approach gave the <a href="https://github.com/evolutionaryscale/esm" target="_blank" rel="noreferrer noopener">developers</a> a chance to encode intricate biological knowledge in a single model with an impressive 98 billion parameters. 



Thomas Hayes from <a href="https://forge.evolutionaryscale.ai/" target="_blank" rel="noreferrer noopener">EvolutionaryScale Forge</a> and colleagues used this model to produce a fluorescent protein with a genetic sequence that is far removed from anything seen before.



<h2 class="wp-block-heading" id="h-leaping-through-time">Leaping through time</h2>



“We found a bright fluorescent protein at a far distance (58% sequence identity) from known fluorescent <a href="https://www.earth.com/news/futuristic-food-supply-transforming-co2-into-protein/" target="_blank" rel="noreferrer noopener">proteins</a>, which we estimate is equivalent to simulating five hundred million years of evolution,” said Thomas Hayes, who led the study.



This method explores sequence space far beyond the scope of typical lab experiments. While labs traditionally direct mutations step by step, ESM3 can jump to regions of protein space that look like they arose eons ago.



<h2 class="wp-block-heading" id="h-ai-analyzing-billions-of-proteins">AI analyzing billions of proteins</h2>



The training <a href="https://www.fpbase.org/" target="_blank" rel="noreferrer noopener">data</a> for ESM3 is unusually large. Its developers compiled 771 billion unique tokens from around 3.15 billion protein sequences, 236 million three-dimensional structures, and 539 million annotated functions.



This variety helps the model see patterns that might otherwise remain hidden. It also offers a view of how <a href="https://www.earth.com/news/junk-proteins-responsible-for-aging-cause-als/" target="_blank" rel="noreferrer noopener">different proteins</a> fit together and carry out biological tasks.



This depth of insight has led to speculation that ESM3 may help us fill gaps in our knowledge of how proteins fold and what structural elements matter most.



<h2 class="wp-block-heading" id="h-why-fluorescent-proteins-matter">Why fluorescent proteins matter</h2>



Fluorescent proteins light up under specific conditions, making them indispensable in microscopy and related imaging. They help scientists see inside cells and observe processes that used to be invisible.



Many labs rely on natural fluorescent proteins, often modified through traditional protein engineering. <a href="https://www.earth.com/news/chatgpts-carbon-footprint-is-astronomical-and-not-sustainable/" target="_blank" rel="noreferrer noopener">AI-driven methods</a> like ESM3 may speed up that work, offering faster alternatives for researchers who want to customize these proteins or discover entirely new ones.



Some investigators <a href="https://pubmed.ncbi.nlm.nih.gov/35348602/" target="_blank" rel="noreferrer noopener">predict</a> that such AI tools will be a boon for projects in which large, complex data sets are needed for rational protein design.



<h2 class="wp-block-heading" id="h-ai-designed-proteins-and-health">AI-designed proteins and health</h2>



The same reasoning that leads ESM3 to create an unexpected fluorescent <a href="https://www.earth.com/news/rare-genetic-mutation-has-given-rise-to-a-new-blood-group-mal-system/" target="_blank" rel="noreferrer noopener">protein</a> can apply elsewhere. AI models can suggest ways to make enzymes more stable in challenging environments or build proteins that capture and break down pollutants.



Drugs might also be developed more quickly by zeroing in on promising protein targets. In many cases, success hinges on spotting crucial patterns across countless variations.



That is where a wide-training model like ESM3 stands out. Researchers say it is poised to <a href="https://pubs.acs.org/doi/10.1021/ar960017f" target="_blank" rel="noreferrer noopener">support</a> innovation in medicine and environmental technology.&nbsp;



<h2 class="wp-block-heading" id="h-esm3-ai-new-way-to-program-proteins">ESM3 AI: New way to program proteins</h2>



ESM3’s release in public beta means any curious scientist can start to experiment with an API. There is also a browser-based interface that invites users to explore protein options without diving into code.



This broader access may spark unexpected collaborations. People working on renewable energy, biomedical devices, or synthetic biology might all find themselves using this <a href="https://www.earth.com/news/cracking-the-code-of-life-the-secret-language-of-dna/" target="_blank" rel="noreferrer noopener">AI to craft proteins</a> that were never seen in nature.



Despite the excitement, experts remind us that real-world protein applications need careful validation. AI models like ESM3 may propose structures that look good on paper but require detailed lab checks.



Still, many researchers argue that these tools will save time and money, fueling experiments that push beyond the usual boundaries of what proteins can do. The high capacity of ESM3 and similar models suggests that this field will keep growing.



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



ESM3’s method of handling sequence, structure, and function as a unified puzzle has opened doors that were locked by the limitations of older technology. This is more than a clever trick.



It hints at future <a href="https://www.earth.com/news/ai-is-the-next-frontier-in-cancer-treatment/" target="_blank" rel="noreferrer noopener">AI-driven pipelines</a> where scientists quickly generate ideas for new proteins and test them with robotic labs. The approach points to a time when evolving proteins by design is as natural as editing text on a screen.



It may be a sign that we have only scratched the surface of what AI can accomplish in biology.



The study is published in <a href="https://www.science.org/doi/10.1126/science.ads0018" target="_blank" rel="noreferrer noopener">Science</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.

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



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



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



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

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



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



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

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



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



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



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



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



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

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.
