For decades, scientists treated the yellow-eyed penguin (Megadyptes antipodes) as a single species split into two broad populations. A new genomic study...
A new analysis of 470 flowering plant species finds that whole-genome duplication surged precisely during Earth’s violent environmental crises, suggesting...
Using environmental DNA (eDNA) collected from waters more than 4 km deep off Western Australia’s Nyinggulu (Ningaloo) coast, researchers identified a...
New research reveals that 3.4 billion years ago (Archean Eon), ancient microbes relied on molybdenum — a metal that was vanishingly rare at the time...
A landmark study of several butterfly lineages and a day-flying moth in South America shows that convergent evolution — when unrelated species arrive...
A comprehensive genome-wide analysis of Amazonian two-toed sloths (genus Choloepus) suggests the animals are more genetically diverse than once believed,...
In the lightless depths of the Gulf of Alaska, approximately 3,251 m (two miles) below the surface, a softball-sized golden object clinging to a rock left...
In a large clinical trial, Tufts University researcher Bess Dawson-Hughes and colleagues found that vitamin D supplements reduced diabetes risk only in...
Mitochondrial DNA (mtDNA) from eight fossils found in Stajnia Cave in Poland reveals a tight-knit group of Neanderthals who lived about 100,000 years ago,...
The Galápagos lava heron, a small heron that stalks the lava-strewn shores of the Galápagos Islands, Ecuador, may finally have secured its place as a...
Scientists have extracted and analyzed DNA from 216 canid remains, including 181 from Paleolithic and Mesolithic Europe. The oldest data that they recovered...
A team of researchers from the United States and Germany has identified fungal proteins that can freeze water at relatively warm subzero temperatures,...
Genetic and acoustic evidence show that the rare Ijima’s leaf warbler (Phylloscopus ijimae) is actually two distinct bird species, including the newly-identified...
In a randomized clinical trial of older adults, researchers found that taking multivitamins for two years modestly slowed epigenetic markers of aging —...
Prehistoric humans and Neanderthals didn’t just interbreed, they did so with a consistent sex bias, as male Neanderthals and female modern humans mated...
The ancestors of today’s malaria-spreading mosquitoes in the Anopheles leucosphyrus (Leucosphyrus) group may have shifted to feeding on humans around...
Scientists have isolated a new strain of the Psychrobacter cryohalolentis species from 5,000-year-old ice from Scarisoara Ice Cave in Romania. Remarkably,...
Between 73,000 and 20,000 years ago (Late Pleistocene), the Japanese Archipelago was inhabited by cave lions (Panthera spelaea), according to a new genetic...
