Here's a sobering thought: Wild birds — including city pigeons and ubiquitous Canada geese — carry 170 different types of bird flu. You know, all those viruses with the Hs and Ns in their names, like H1N1 and H5N1.
Only a dozen of these viruses have infected humans so far, but many of those have been deadly, and three of them have caused global flu pandemics.
Does every bird flu that leaps into people have the potential to turn into the next "big one" that spreads rapidly around the world?
From southern Virginia to New England, lots of people are being treated to a cicada serenade. If these insects sound loud to you, that's because they are. They're so loud that some Navy engineers are trying to borrow their technique.
The origin of the first primates — the group that includes humans, apes and monkeys — is thought to lie in the deep past, about 55 million years ago.
Fossils from that period are rare. But now, there's an exciting new one. It's called Archicebus achilles, roughly meaning "beginning long-tailed monkey." Actually, this creature lived before the monkeys we know of today, a mere 10 million years after the dinosaurs died out.
For Percival Zhang, growing up in China meant learning to appreciate just how critical a stable food supply is to avoiding social unrest and disasters like famine.
When he became an associate professor of biological systems engineering at Virginia Tech, he got to thinking just how risky growing food has become because of the finite resources it requires: land, water, seeds and fertilizer.
Plenty of other plants on Earth, on the other hand, aren't so demanding.
If you're looking for the definitive study that might persuade meat lovers to become vegetarians, this may not be it.
New research published in JAMA Internal Medicine finds that vegetarian diets are linked to a slightly lower risk of early death — about 12 percent lower over a period of about six years of follow-up. But the link to longevity was more significant in men compared with women.
The French weren't the first to make wine? Mon dieu! But as anyone who has sipped a Bordeaux, Champagne or Burgundy can tell you, the French got pretty good at it once they learned how. And thanks to some molecular archaeology, researchers can now confirm they picked up these skills as early as 425 B.C.
So who taught the French the art of viniculture? Probably the ancient Italians, says the man with perhaps the coolest nickname in science research — the "Indiana Jones of alcohol," Patrick McGovern.
Mississippi lawmakers have embarked on a controversial campaign to discourage older men from having sex with teenagers.
Starting in July, doctors and midwives in the state will be required by law to collect samples of umbilical cord blood from babies born to some girls under the age of 16. Officials will analyze the samples and try to identify the fathers through matches in the state's DNA database.
If you could travel back in time about 8 million years, you'd find a creature in an African tree that was the ancestor of all current apes and humans. And that creature in all likelihood would have spent a big part of its day munching leaves and fruit — pretty much what apes eat now.
This is the season of night noises, chirps, buzzes, little cries. The air is telling you, "Things are going on out here," and if you like you can step out onto the porch and do what the writer Rachel Carson did back in 1956: She played a hunting game. The rules were simple: You stand outdoors, near the house. You go quiet. When you hear something interesting, you either: a) take a flashlight and go hunt for it; or b) you don't go anywhere. You just imagine it.
The best find Rachel Carson ever made, she never found.
Friday's tornadoes came less than two weeks after an F-5 tornado destroyed a large section of Moore, just south of Oklahoma City. Both episodes raise two sides of one question: When caught in a tornado's path, should you run or hide?
For Morning Edition the day after the powerful tornado on May 20, NPR's Wade Goodwyn spoke with Molly Edwards, who was covered in pink insulation and standing on the rubble of her home with her family.
Hurricane season begins Saturday, and the National Oceanic and Atmospheric Administration is forecasting an active season, with perhaps seven to 11 hurricanes.
With memories of last year's destruction from Hurricane Sandy still fresh, meteorologists are working on ways to improve how they forecast storms and communicate warnings to the public.
When Sandy was making its way northward in the Atlantic and began to turn toward the East Coast, the National Hurricane Center tried to emphasize the danger that storm surge posed for residents, especially those near New York City.
