This mash-up of data from the James Webb Space Telescope and the Chandra X-ray Observatory reveals two galaxies mid-collision, with their spiral arms overlapping and bending toward their neighbors' co...
A satellite photo from July shows intricate snowy stripes painted across the Atacama Desert in Chile. The icy weather temporarily put the Atacama Large Millimeter/submillimeter Array (ALMA) observator...
A small study reveals that cats greet male owners more vocally than female ones. But the findings could be a result of cultural norms among the participants, rather than a universal cat behavior, scie...
Much of the western U.S. is overdue for wildfire, with decades of suppression allowing fuel to build up across millions of hectares. Researchers estimate that 74% of the region is in a fire deficit, m...
Researchers announced over 70 new species in a single year, including bizarre insects, ancient dinosaurs, rare mammals, and deep-river fish. Many were found not in the wild, but in museum collections,...
A new bioluminescent tool allows neurons to glow on their own, letting scientists track brain activity without harmful lasers or fading signals. The advance makes it possible to watch individual brain...
Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ov...
A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed bett...
Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded...
Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike crater-formin...
Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found predato...
Spending a few hours a week helping others may slow the aging of the brain. Researchers found that both formal volunteering and informal acts, like helping neighbors or relatives, were linked to notic...
Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some cance...
Firefighter turnout gear is designed to shield first responders from extreme heat and danger, but new research suggests it may also introduce chemical exposures. A U.S. study found that brominated fla...
After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communica...
