Ancient encounters between humans and the mysterious Denisovans are still shaping people today. By analyzing genomes from populations across the Pacific, researchers uncovered evidence that the ancestors of Near Oceanians interbred with at least ...

A newly identified crocodile species nicknamed "Lucy's hunter" prowled Ethiopia's rivers when Lucy's species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have ...

Alaska's glaciers are proving to be highly sensitive to warming temperatures. Using radar satellites to monitor more than 3,000 glaciers, researchers found that every 1°C (1.8°F) increase in average summer temperature extends glacier melting by ...

A spectacular fossil fish discovered on a remote cliff in New Zealand nearly 30 years ago has finally revealed its full story thanks to an unexpected discovery: the original collector's long-lost field notebooks. The 1.2-meter fossil, preserved in .. ...

Researchers in South Korea have recreated the legendary "sea silk" once prized by emperors, using fibers from a clam cultivated in Korean coastal waters. They discovered that its famous golden shine comes from tiny protein structures that reflect ...

A tiny set of ancient genetic "switches" may have played a surprisingly large role in making human language possible. Researchers found that these DNA regions, which act like volume controls for genes involved in brain development, have an outsized . ...

A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers discovered the parasite, Echinococcus ...

For nearly 700 years, Indigenous hunters repeatedly used a bison kill site in central Montana--then suddenly stopped, even though bison were still abundant. Researchers uncovered evidence that recurring, decades-long droughts likely made the site ...

Scientists have developed biodegradable protein beads made from dairy and tofu waste that can capture carbon dioxide from the atmosphere more efficiently than many current technologies. Unlike conventional systems that require large amounts of energy ...
