From chewed birch pitch, scientists recovered DNA from an ancient woman and her mouth microbes and hazelnut and duck DNA from a meal she’d consumed.
Birds are migrating earlier in recent decades in the United States, which could disrupt feeding or nesting cycles.
Fossils in amber push the origin of feather-feeding insects back over 50 million years, a study finds.
Recordings from underwater microphones on stealthy robotic gliders could create a better “soundscape” of noises throughout the ocean, researchers say.
Science & Society
A strongly dominant eye, not an eye disorder, may explain why some great artists painted themselves with one eye turned outward.
Devil worms have many extra copies of genes tied to heat stress and cell death, which may help the critters survive deep underground, a study finds.
Health & Medicine
Blocking the protein may hinder B cells invading the brain in multiple sclerosis, a study in mice and ‘stand-in’ human brain barriers finds.
Caribou in Alaska and Canada migrate up to 1,350 kilometers round trip each year, a study reports.
Some women who appear to lack the brain structures that relay scent messages still have an average sense of smell, and scientists have no idea how.
Rows of tiny stemlike rods called SunBOTs orient themselves toward light, optimizing the solar energy that they can harvest.
Scientists may have figured out how scandium fluoride crystals shrink as temperature rises, possibly leading to new insights into superconductors.
