Your cat's purr may say more about who they are than their meow ever could. Scientists discovered that purrs are stable and uniquely identifiable, while meows change dramatically depending on context. Domestic cats, in particular, have evolved highly ...

Hundreds of millions of years ago, the first animals to crawl onto land were strict meat-eaters, even as plants had already taken over the landscape. Now scientists have uncovered a 307-million-year-old fossil that rewrites that story: one of the ...

A bonobo named Kanzi surprised scientists by successfully playing along in pretend tea party experiments, tracking imaginary juice and grapes as if they were real. He consistently pointed to the correct locations of pretend items, while still ...

Around 1550, life on Rapa Nui began changing in ways long misunderstood. New research reveals that a severe drought, lasting more than a century, dramatically reduced rainfall on the already water-scarce island, reshaping how people lived, worshiped, ...

Methane levels in Earth's atmosphere surged faster than ever in the early 2020s, and scientists say the reason was a surprising mix of chemistry and climate. A temporary slowdown in the atmosphere's ability to break down methane allowed the gas to .. ...

Life's story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these rare genes, researchers can investigate how early ...

Satellite imagery reveals how the 2026 Winter Olympics are spread across northern Italy, from alpine valleys to historic cities. Events are hosted in mountain resorts, while Milan and Verona frame the Games with opening and closing ceremonies. The .. ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be .. ...

Forests around the world are quietly transforming, and not for the better. A massive global analysis of more than 31,000 tree species reveals that forests are becoming more uniform, increasingly dominated by fast-growing "sprinter" trees, while slow ...

A common iron mineral hiding in soil turns out to be far better at trapping carbon than scientists realized. Its surface isn't uniform -- it's a nanoscale patchwork of positive and negative charges that can grab many different organic molecules. ...
