Samples of Beethoven's hair reveal he may have suffered from lead poisoning, which could explain some of the difficult physical maladies the composer suffered in his life.

Tiger beetles generate "anti bat-sonar" to prevent echolocating bats from eating them, scientists say. An experiment suggests the beetles mimic sounds created by poisonous insects that bats avoid.

Lebanon offers a glimpse into history, with a treasure trove of specimens that have been sealed away for millennia in ancient amber.

Scientists say a teenager and her father discovered fossilized pieces of a jawbone that belonged to an ancient marine reptile — perhaps the largest ichthyosaur ever found.

We meet a brother and sister who share an oddity and in their family, this quirk is unique to them. Sharing an oddball trait isn't that common with siblings unless you're an identical twin.

Little insects pee in droplets. But it turns out that cicadas pee in jets — and why and how they do it could help scientists better understand microfluidics and advance all kinds of technologies.

The constant state of crisis in Haiti is taking a toll on health care facilities in the country. Some doctors and staff are no longer showing up at hospitals for fear of being kidnapped.

Scientists identified an 11th-century astrolabe with Arabic inscriptions and Hebrew writings, highlighting a period when Muslims ruled in present-day Spain and scholarship and idea-sharing flourished.

The words "coral reef" evoke a riot of color and life. But the ecosystem's disappearing. Now, new evidence points to an ally for the coral reef: a little creature called the sea cucumber.

Science magazine's annual contest "Dance Your PhD" invites grad students to present their research through dance. This year's winner, Weliton Menário Costa, showcased his work on kangaroo behavior.

Scientists have found what they say could be one of the oldest Stone Age megastructures in Europe: a giant stone wall on the floor of the Baltic Sea. They've dubbed it the "Blinkerwall."

A new study shows that an Ebola vaccine can cut mortality figures of those infected in half.

For decades, the number of California sea otters cratered. But they've been making a comeback — and are helping curb erosion along the coast by eating the crabs that accelerate it.

Scientists have found that spiderwebs can be used to capture environmental DNA, which reflects the animal population of an area. The technique may help track the biodiversity of an ecosystem.

The megalodon went extinct 3.6 million years ago and is thought to be the largest shark that ever swam the Earth — until now. (Story first aired on All Things Considered on January 23m 2023.)

The megalodon went extinct 3.6 million years ago, and is thought to be the largest shark that ever swam the Earth. But the megalodon may not have been as big as once thought, some researchers suggest.

Newly discovered kelp fossils peg their existence to 32 million years ago. These fossils may help explain how the Pacific Ocean's underwater 'forests' came to be.

The telescope has revealed the earliest known black hole to date, and it's millions of times larger than our sun.

For decades, researchers have said that our mammalian ancestors were solitary but a new analysis turns that thinking on its head, suggesting they were far more sociable than was previously thought.
