Ancient remains from Vietnam suggest diseases like yaws may have been passed from mother to child thousands of years ago, a form of transmission often assumed to indicate syphilis. The discovery could overturn how scientists interpret ancient ...

Scientists probing life's deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share one ancient genetic code, yet have undergone two ...

Dogs may understand our emotions more deeply than scientists realized. Brain scans show that happy human faces activate regions in dogs linked to higher-level processing and reward, suggesting that smiles carry special emotional significance for them ...

Scientists have created an unusually corrosion-resistant stainless steel that could replace costly titanium components used to produce green hydrogen. The breakthrough could reduce structural material costs by roughly 40 times and make seawater-based ...

Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger harmful algal blooms, reduce seafood supplies, disrupt . ...

A forgotten fragment of a lost papal letter is offering a surprising new explanation for the Norman Conquest. England may have backed the wrong pope during a bitter religious power struggle, giving Pope Alexander II a political reason to support ...

A spectacular 150-million-year-old trail of more than 130 footprints captures a giant sauropod making a complete loop before continuing on its way. Its uneven stride hints that the long-necked dinosaur may have been walking with a limp.

Researchers can now recover DNA from centuries-old parchment without damaging the manuscripts, turning historic documents into unexpected genetic time capsules. The hidden clues could reveal ancient trade routes, livestock history, manuscript origins ...

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many ...

The rise of the potato in the Andes appears to have left a lasting mark on human DNA. Indigenous Peruvians carry exceptionally high numbers of a starch-digestion gene, likely because people with more copies gained an evolutionary advantage once ...
