Lead exposure lowers children's IQ and causes aggression. But children exposed to low levels of lead show different symptoms, including more depression and anxiety, a study of preschoolers finds.
An earlier version of the satellite crashed into the ocean near Antarctica shortly after launch. Scientists are keeping their fingers crossed for the second attempt.
NASA is asking the public to help it develop new ways to bring their technology to the commercial market. Daniel Lockney of NASA tells us more about this crowdsourcing, profit-sharing initiative.
The future of good barbecue isn't in new technology, but in the old way of cooking with wood and smoke, says one expert. The science of slow-cooked meat seems to support his argument.
Video chatting with a therapist is convenient, people who have tried it say. Research suggests online therapy can be effective, but issues with the quality of the service and privacy remain unsolved.
Geneticist Razib Kahn sequenced the entire genome of his unborn son. He tells NPR's Don Gonyea why he mapped the gene sequence and what he found: His son won't be a picky eater.
Space is a premium in space. So NASA ended up folding two rovers inside a shipping container, and then unfolding them when they landed. This story originally aired on All Things Considered on July 9.
They were having a baby. Both she and her husband carry a gene that might cause problems, "might" being a 25 percent chance. Is that high? Low? What to do? Here's the story, nicely drawn, deeply felt.
In 1864, Abraham Lincoln set aside the nation's first federally-protected wilderness areas. Visitors have enjoyed Yosemite's wonders ever since — sometimes to the point of endangering them.
Passenger pigeons used to be the most abundant bird in North America. But hunters drove them to extinction, and by 1914, only one was left. A century later, that pigeon, named Martha, is on exhibit.
As part of the series "Unfolding Science," NPR's Joe Palca presents the science of protein folding. A properly folded protein keeps you alive; a misfolded protein can kill you.
To stop deaths from heat stroke, specialists say athletes and the rest of us should ease into a new sport, drink extra fluid, and — most importantly — get cool fast when body temperature spikes.
Hospital-acquired infections with Staphylococcus aureus are a major health problem. Learning how staph can gum up tiny tubes like catheters may help prevent infections.
A high school chemistry teacher in the UK started honing his visual talents by making posters for students. Now his infographics about food science and chemistry basics are a hit on the web.
Porcine epidemic diarrhea virus has killed more than 7 million piglets in the past year. There's no cure, but a vaccine that may protect piglets has been approved even though it's still being tested.
This technique for manipulating genes borrows a strategy from the way bacteria fight viruses. It's still experimental, but the possibilities excite medical researchers hoping to tailor treatments.
Bits of 50,000-year-old poop have provided scientists with clues into what our early Neanderthal ancestors ate. Rather than subsisting on meat alone, the poop suggests they also ate plants.
Unrelated lineages of electric fish all use the same small set of genes to create their voltage, a genetic search shows. Maybe the same genes could one day power pacemakers, bioengineers suggest.
This bird likes livers, kidneys, entrails — anything it can pluck that's freshly dead. But what if you served it ... a painting?
Research shows narcissists can be induced to make environmentally positive purchases when those purchases are linked to the things narcissists value — prestige, status and image.
