In a study published in The New England Journal of Medicine, researchers reported an association between daily nut consumption and a reduction in the risk of dying from cancer, heart disease, and other major chronic diseases. Lead author Charles Fuchs discusses these findings.
When astronomers spotted Comet ISON in 2012, some christened it the "Comet of the Century." It initially failed to live up to the hype. But this month, ISON blazed brighter and sprouted several tails. Astronomers like Andrew Fraknoi are following the comet as it scrapes past the sun, where it could be destroyed--or emerge, even more spectacular than before.
In the Leidenfrost Effect, a water droplet will float on a layer of its own vapor if heated to a certain temperature. This common cooking phenomenon takes center stage in a series of playful experiments by physicists at England's University of Bath, who discovered new and fun means to manipulate the movement of water.
This is SCIENCE FRIDAY. I'm Ira Flatow. Those of us of a certain age can remember exactly what we were doing on a Friday this hour 50 years ago when we heard the news. President Kennedy's assassination horrified and transfixed the nation. It was murder in plain sight, seemingly the easiest kind of crime to solve. But 50 years later the basic facts of the case are still debated.

Many organic farmers are hopping mad at the U.S. Food and Drug Administration, and their reason involves perhaps the most underappreciated part of agriculture: plant food, aka fertilizer. Specifically, the FDA, as part of its overhaul of food safety regulations, wants to limit the use of animal manure.
"We think of it as the best thing in the world," says organic farmer Jim Crawford, "and they think of it as toxic and nasty and disgusting."
NPR's Richard Harris has covered the U.N. climate talks since the first treaty was negotiated in Rio de Janeiro in 1992. He's monitoring these new talks, and he joins us now to talk about this long-running argument over climate-related funding for the developing world. Richard, thanks for being here.
RICHARD HARRIS, BYLINE: My pleasure.
BLOCK: And we just heard Mr. Khan mention this goal of $100 billion in aid per year, starting in 2020. He thinks that's realistic. What does it look like from where you sit?

We're going to spend the next few minutes talking about climate change and a campaign being waged by some of the world's poorest countries. U.N. climate talks are underway in Warsaw right now. And there, a group of developing nations is demanding that wealthy countries accept responsibility for global warming, provide financial support and pay for losses due to climate change.

This year, Americans are expected to buy more than $30 billion worth of organic grains, produce, coffee, wine and meats.
