Scientists have cracked open the “black box” of feline cancer in a landmark study that genetically analyzed nearly 500 cat tumors from around the world. The research uncovered striking similarities between cancers in cats, dogs, and humans — including shared cancer-driving genes tied to aggressive breast cancers.

Scientists have uncovered the oldest known hand-held wooden tools ever used by humans — and they’re an astonishing 430,000 years old. Buried for hundreds of thousands of years at an ancient lakeside site in Greece, the carefully carved wooden objects reveal that early humans were far more skilled and resourceful...

Scientists found that storing mangoes at 54°F dramatically slows ripening and keeps the fruit fresh far longer than typical tropical temperatures. The cooler conditions helped mangoes stay firm, retain moisture, and preserve important antioxidants while reducing cellular damage. Researchers also uncovered the internal defense systems that switch on during cold...

A breakthrough lithium-extraction method could help solve one of clean energy’s dirtiest problems. Researchers at Columbia Engineering have developed a fast new technique that pulls lithium directly from salty underground brines using a temperature-sensitive solvent, avoiding the giant evaporation ponds that can take years and drain precious water supplies. Even...

The world’s oceans are rising at an accelerating pace, and scientists now say they can fully explain what’s driving it. Warming seawater is the biggest factor, while melting glaciers and polar ice sheets are increasingly pouring more water into the oceans each year. Researchers also solved a puzzling mismatch in...
