A new study uses boreholes drilled deep beneath Antarctic ice to investigate why the continent’s glaciers are accelerating. More than half a kilometer beneath an East Antarctic glacier, sensors detected water pressure high enough to support almost all the ice above. The measurements provide the first direct confirmation that meltwater from the surface can reach […]

Ancient Dog Skulls Rewrite the Story of Canine Evolution
Ancient bones and DNA reveal that dog diversity and their close relationship with migrating humans developed thousands of years ago. Place a village dog beside a toy poodle and a mastiff, and the extraordinary physical range of a single species becomes obvious. An estimated 700 million dogs now live alongside or near humans worldwide. Dogs […]

Researchers Reveal a Hidden Biological Clock in Insects
Humidity governs the daily rhythms of some insects, raising the question of whether it affects humans too. Inside a tightly controlled chamber, kissing bugs, fruit flies, mosquitoes, and spider beetles adjusted their behavior to repeating changes in humidity. Even after researchers removed the humidity cycle, the insects continued following the established rhythm of moist and […]
