The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.
A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first
In just one course, Georgia Tech student Diya Godavarti helped develop a tool that could improve workers' responses to chemical spills or open containers. Godavarti, then a second-year chemical and biomolecular engineering (ChBE) student, joined a course on chemical equity
European countries continue to lead the world in environmental performance, according to the 2026 Environmental Performance Index (EPI), a biennial assessment produced by researchers at the Yale Center for Environmental Law & Policy and Columbia Climate School's Center for
Research on Southwest Florida cyanobacterial blooms shows that the toxins they produce are aerosolized and potentially inhaled by people far from contaminated water bodies.
Chemists from Otto von Guericke University Magdeburg have achieved an important research success in the fight against resistant bacteria. The team led by scientist Professor Dr. Dieter Schinzer from the Institute of Chemistry has succeeded in producing key building blocks of
In a new paper published in the Proceedings of the National Academy of Sciences, a team of 41 authors from around the globe argue that virtual reality has the potential to do the same for behavioral science and help solve the reproducibility crisis.
The spacecraft aced its encounter with Mars. Now, mission scientists are studying a trove of data from the flyby in preparation for its arrival at asteroid Psyche in 2029.
The immune system, the body's defense network against infections and injuries, can sometimes become too active. In these cases, it can produce too many immune mediators, fragments of genetic material or proteins that regulate immune responses.
If you've driven down two-lane highways in rural parts of North Florida recently, you may have noticed a spate of new signs that designate the grassy knolls bordering the asphalt as wildflower areas. The signs likely feel redundant right about now as thousands of milkweeds
More than 2,700 people are estimated to have died from heat-related causes during the record-breaking May and June 2026 heat waves in England and Wales, according to a new rapid analysis report led by researchers from the London School of Hygiene & Tropical Medicine (LSHTM),
Researchers at Washington State University have discovered a molecular "winter lock" that keeps animals in a less active winter state until favorable conditions return, a discovery that could improve pest control and lead to a better understanding of seasonal health conditions
People experiencing homelessness, victims of domestic violence and economically vulnerable people are at higher risk of social exclusion. For them, pets are an important source of emotional support. A study by the Affinity Foundation Chair for Animals and Health of the
In a research lab at the University of Tokyo, scientists have developed a new kind of glue. It's incredibly strong and highly stretchable, yet it washes away completely with a little alcohol.
Ireland's waters continue to provide an important seasonal refuge for the endangered basking shark, according to a new study.
If you want to beat the heat of the summer sun, slowing down and doing less is a good strategy. However, researchers have long asked whether the same occurs at the cellular level. While cellular stress responses have been repeatedly studied, the impact of the environment on
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive
Quantum computers, devices that process information by leveraging the laws of quantum mechanics, have been found to outperform classical computers in some advanced tasks. Instead of storing information in the form of classical binary bits (i.e., 0 or 1), quantum computers rely
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The
India's first privately built orbital rocket took its maiden flight Saturday, its company said, marking a significant step for the South Asian giant as it eyes a bigger slice of the global space economy.
Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal layers cut through by vast
A new paper in the journal Nature Physics offers insights into the physics of liquid droplets—and while many people may not appreciate the mathematical accomplishment, they will benefit from the athletic wear and raincoats it makes possible. The recent article, "Tricky
A technology has been developed that allows artificial intelligence to inversely determine the process conditions for quantum-dot light-emitting diode (QLED) devices—conditions that previously required extensive trial and error to identify.
A 12-week intermittent fasting program produced weight-loss benefits that were still visible a year later. Participants who ate within an eight-hour window maintained more weight loss than those who followed their usual longer eating schedule. Both early and late eating windows
Editor in Chief Nancy Shute discusses the history of unethical practices in research on human remains and the progress toward more ethical standards.
Spoonerisms are among the most well-known speech errors, and for linguists and psychologists they offer a glimpse into how our brains produce speech
The United Nations looks set to list a Biblical site, Lebanese castles, an antelope migration path and the world's deepest lake as world treasures under threat, including from war or climate change.
Millions of people in the Great Lakes, Northeast and Mid-Atlantic states muddled through another day of unhealthy air from uncontrolled wildfires on Friday.
Europe's great cormorant has recovered from near extinction to overabundance in half a century, stoking a long-running debate over population control between fishers troubled by its voracious appetite and conservationists.
America's most daring, extraordinary feat—landing astronauts on the moon—remains the pinnacle of achievement by anyone anywhere. Ever.
