A hidden crater in South Korea may hold clues to one of the biggest turning points in Earth’s history: the rise of oxygen. Scientists discovered fossil-like stromatolites — layered structures built by ancient microbes — inside the Hapcheon impact crater, suggesting that
Researchers have discovered that the GLP-1 hormone targeted by drugs like Wegovy is present in very low amounts inside the joints of arthritis patients. That finding suggests high-dose GLP-1 medications could potentially reach the joints and influence inflammation directly, not
Scientists are uncovering a surprising truth about aging cells: some may damage the body, while others help protect it. The discovery is fueling a new wave of precision anti-aging therapies aimed at removing only the harmful “zombie” cells without disrupting the body’s natural
In many underwater ecosystems, seagrass meadows act as a food source, a safe haven, and an ecological lynchpin. But until now, very little was known about how these plants reproduce—critical information for conserving the meadows.
A new study divides Brazil into 48 zones, each defined by its climate and soil conditions. Restoration projects can use these zones to identify which native seeds are best suited to each location under both current and future climates.
Mysterious red auroras spotted over Japan were found reaching astonishingly high altitudes, even during space storms considered relatively mild. The discovery suggests hidden solar activity may be stronger than scientists realized — with potential consequences for satellites
Astronomers using NASA’s James Webb Space Telescope have uncovered a rare world unlike anything in our solar system — a giant planet about the size of Saturn with surprisingly Earth-like temperatures and an atmosphere packed with methane. The planet, TOI-199b, sits more than
Researchers have demonstrated that different types of paper industry sludge, typically treated as a low-value waste, can be transformed into a high-yield renewable biofuel. The study, published in Biofuels, Bioproducts and Biorefining, reveals that paper sludge streams vary
A new theory suggests many age-related diseases may actually start decades before symptoms appear. Researchers say early-life damage — from infections, injuries, or genetic mutations — can remain hidden until aging weakens the body’s ability to keep it under control. This could
A new study from the University of East London has found that companies led by long-serving chief executives may become less innovative over time unless challenged by strong independent boards. The research examined 215 FTSE 350 companies over an 11-year period between 2010 and
Many people avoid learning a new language because they remember stressful grammar lessons or fear making mistakes. But language experts say communication, culture, and connection matter far more than perfection. Modern apps, entertainment, travel, and online communities have
Researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have found new indications of how large prehistoric settlements were organized. Their research focused on a special type of building known as a megastructure. Excavations in Romania have now shown that

Two-thirds of Americans want action on climate change, but people vastly underestimate public support for climate solutions and policy. Historically, U.S. news outlets overrepresented views on climate change that went against scientific consensus. If news outlets are similarly
When fire tore through Los Angeles County in January 2025, westerly winds blew most of the smoke and ash over the Pacific, keeping the main measure of air quality, total mass of particles smaller than 2.5 microns, at or near normal levels.
Complexity may seem subjective, but a quantitative measure of the complexity of nanomaterials was recently developed by a team of researchers from the University of Michigan Engineering, the University of Southern California Viterbi School of Engineering and the University of
The 8.1-meter Gemini North telescope, located on the summit of Maunakea in Hawai'i, has captured NGC 1514, nicknamed the Crystal Ball Nebula, in awe-inspiring detail. This nebula, with its mesmerizing glow of gas, harbors hints of a past stellar death, and its asymmetrical
Long before his days of research, Christian Couch was just a kid marveling at the butterflies in the Florida Museum of Natural History's Butterfly Rainforest. Years later, after enrolling as an undergraduate student at the University of Florida, that same sense of wonder led
Precision medicine aims to transport therapeutic agents, such as molecules, proteins or RNA, to the exact place where they need to act within the body. One of the most promising strategies is the use of nanocarriers: nanoparticles capable of encapsulating the drug, protecting
Large numbers of college students are now using artificial intelligence to complete—and cheat on—their assignments, suggesting that colleges and universities need to change how they are evaluating students, finds new Cornell research. An analysis of survey responses from more
When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, where scientists try to detect extremely small
Technology that converts carbon dioxide (CO₂) into fuels and plastic feedstocks using electricity is gaining attention as a core technology in the era of carbon neutrality. In particular, ethylene and ethanol are high-value materials widely used in the production of plastics,
A collaborative research team from Kanazawa University and Kyoto University reports the successful visualization of how densely assembled macrocyclic host molecules cooperatively capture guest molecules on a surface. Using two advanced atomic force microscopy techniques, AFM,
About two billion people—just under a quarter of the world's population—lack regular access to clean drinking water, and roughly 800,000 people annually die from illnesses associated with unsanitary water.
Northwestern Medicine scientists have developed a new experimental method to analyze conformational fluctuations in protein domains on a uniquely large scale, which may improve data-driven modeling, biology and protein engineering, as detailed in a recent study published in
When people eventually head to the moon for long-term exploration and habitation, they'll need equipment and spacesuits made of well-tested materials. That's where NASA's Lunar Environment Test Rig (LESTR) comes in handy. It simulates extreme cold lunar night conditions right
Scientists have reported it for decades: overpopulation can impair reproduction. Crowded chickens lay fewer eggs. Crowded mice have smaller broods. In humans, several studies have associated increased population density with reduced fertility.
