This artist’s concept depicts a tidal disruption event, which occurs when a star passes fatally close to a supermassive black hole. Crumbs of the splintering star heat up as they swirl around the black hole, creating a glow astronomers can see from far across the cosmos, and the black holeContinue Reading

Lake fly larvae plunge more than 200 meters into Lake Malawi each day to hide from predators, using tiny air sacs to control their depth. A rubber-like material called resilin lets them expand or shrink the sacs by changing their pH. Their toughness challenges a popular explanation for why insectsContinue Reading

A notorious snake invasion that devastated Guam’s native birds may have succeeded because the reptiles carried hidden genetic advantages. Using advanced long-read DNA sequencing, researchers uncovered more than 19,000 large genetic differences in brown tree snakes, many concentrated in genes tied to immunity and smell. This overlooked diversity may haveContinue Reading
Giant sequoias are built to withstand ordinary fires, but recent extreme wildfires killed thousands of trees that had survived for centuries or even millennia. A new analysis of about 26,400 sequoias found that trees in areas treated with prescribed burns were nearly four times more likely to survive. Researchers estimateContinue Reading
