Ancient teeth and human DNA are revealing a surprising history of insect eating. Modern humans in northern Eurasia appear to have eaten insects only occasionally, while Neanderthals may have consumed ...
The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not pre...
Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for a ma...
Ancient fossils suggest insects conquered land through a long amphibious phase rather than making an abrupt jump from water to dry ground. A newly identified 324-million-year-old species still carried...
Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurren...
Three forgotten Assyrian kings may have been hiding in plain sight for more than 2,700 years. By piecing together clues from tablets, inscriptions, and an ancient statue, researchers argue that these ...
A neuroscientist is challenging the idea that the brain contains a central system that actually “makes” our decisions. What we experience as choosing may instead emerge from the continuous interaction...
Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East Antarctica, building mountains and a high ...
Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these special...
A huge section of Greenland’s Petermann Glacier has snapped off, forming an ice island about the size of Manhattan. Satellites watched cracks spread rapidly before the 76-square-kilometer slab finally...
Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst work...
A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic c...
