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.
Scientists in Siberia say they've extracted blood samples from the carcass of a 10,000-year-old woolly mammoth, reviving speculation that a clone of the extinct animal might someday walk the earth, if scientists are able to find living cells. But researchers say the find, which also included well-preserved muscle tissue, must be studied further to know its potential.
Cities like Houston are dotted with air-sniffing monitors that measure levels of benzene and other potentially unhealthy air pollutants. But those monitors can't answer the question we care about most: Is the air safe?
That's because there's no simple relationship between toxic air pollutants and health risks. Researchers at the University of North Carolina in Chapel Hill are trying to get a leg up on that problem. They are building an instrument that uses human lung cells to measure health hazards in the air more directly.
There's ADHD, OCD, DMDD, PTSD, along with hoarding disorder, oppositional defiant disorder and dissociative identity disorder. You will find all of them in the DSM, that's the Diagnostic and Statistical Manual of Mental Disorders, the so-called Bible of psychiatry. The fifth edition of the manual just came out after 14 years in the making, but instead of a round of applause, psychiatrists, psychologists, ethicists, even columnist are panning the book, saying it has outlived its usefulness.
The book club regulars gather to chat about the best-sellingA Walk in the Woods, writer Bill Bryson's 1998 account of a hiking trip along the Appalachian Trail. Plus, journalist Deborah Blum joins the club to talk about the best science books to stash in your beach bag (or backpack).
This is SCIENCE FRIDAY, I'm Ira Flatow. In 2011, a group of researchers in Japan made a surprising discovery: With the right process, they could turn cement, in fact a component of the Portland cement you can find in the hardware store, they can turn that into a metal, and in its metallic state they could coax the cement to act as a semiconductor.
This is SCIENCE FRIDAY. I'm Ira Flatow. It sounds like something from the movies, but it's true: Researchers unearth an organism frozen inside a glacier, take it back to the lab and discover it's still alive. In this case it's a plant called a bryophyte, a moss that survives being frozen in a glacier in the dark for some 400 years. Wow.
An asteroid nine times the size of a cruise ship is dropping by Earth on Friday, and it's not coming alone. Asteroid 1998 QE2 will be about 3.6 million miles from our planet at its closest approach. And its proximity has already given scientists a surprise: It has its own moon, measured at about 2,000 feet wide.
Brazil is a paradise for birds; the country has more than 1,700 species. Among them is the colorful toucan, a bird with an almost comically giant bill that can be half as long as its body. There are lots of different types of toucan — red-breasted, channel-billed, keel-billed, saffron toucanet — each with its own color-scheme and distinctive call.
