Chemistry is complicated; that includes ingredients in artificially flavored fizzy drinks. Soda makers bowed to pressure to drop brominated vegetable oil, but its safety hasn't been very well studied.
For decades, the speed of racehorses and dogs has stagnated. But humans keep getting faster. On the 60th anniversary of the first time a human ran a mile in under four minutes, we ponder why.
The parents of a young boy made a terrible discovery while looking through photographs they had taken of him as a baby. They noticed a white dot where a black pupil should have been.
Thanks to upwelling, an influx of marine and wildlife is taking place in one of the world's largest underwater canyons in California.
Adelie penguins, which breed in huge colonies on the rocky Antarctic Peninsula, harbor a version of the avian influenza virus. But this strain doesn't make humans or the birds sick.
The U.S. Geological Survey and its state counterpart issued a joint statement saying magnitude 3.0 temblors had increased by 50 percent since October.
Germany's famous Max Planck Society has opened a brain research institute in Jupiter, Fla. It's another move in the international competition to attract the best brain researchers.
Several factors are straining lime production in Mexico from heavy rains to a disease infecting trees. But criminal gangs are adding to the high prices by stealing from orchards and hijacking trucks.
MIT scientist Sebastien Seung at MIT invented the game to help him make a map of the cells in the mammalian retina. A year later, he says the game is producing valuable science.
Climate change has caused rapidly melting ice and thawing permafrost in the Arctic. Once inhospitable to business ventures, economic forecasters are now predicting some $100 billion will be invested there over the next decade. NPR's Arun Rath talks with Isaac Arnsdorf of Bloomberg about the boom.
They are so sleek, so graceful, with such gorgeous eyes, tufted ears — but then they speak. And you think, "Oh no! Why? Why?"
Hundreds of thousands are out of work, yet employers say they struggle to fill positions. Oil refineries in L.A. often have temporary work, but even entry-level jobs require specialized training.
There's a long list of pesky exceptions to the rules organic farmers have to follow for using pesticides and fertilizers. This week, a battle erupted over those exceptions.
It's stink bug season. Robbie Harris of WVTF offers a new trap for these odorous pests: a low-tech solution thought up by Virginia Tech scientists, which can be made for just a couple of bucks.
Scientists have found that the game is less random than it appears because winners tend to replay their winning choice and losers try something else — but according to a predictable pattern.
How come so many species of domesticated animal — dogs, pigs, cows, ducks, geese, rats, horses — have smaller brains than their wild ancestors? Oh, and humans too!
Scientists made human sperm from the skin of men who couldn't make their own sperm naturally. If they prove this actually works, it could mean new ways to treat male infertility.
Researchers have stumbled on a virus that makes crickets horny before it kills them. Inducing your host to mate more is a great way for a virus to spread its own genes.
Two decades after a Cold War-era fence came down, red deer in the Czech Republic remain reluctant to cross into Germany — a fact suggesting that some deer are capable of teaching certain behaviors.
Scientists were able to make immature sperm cells. If they can make the sperm viable, researchers could help men who thought they'd never have kids. But the findings also raise ethical questions.
