50 Years After Landmark Warning, 8 Million Fewer Smoking Deaths

Back in 1964, people smoked cigarettes at work, in restaurants and in grocery stores. Few would have predicted that a report from the U.S. surgeon general would spark a public health revolution that has increased life expectancy in this country by 30 percent.

To Make Healthier Choices, Color-Code Your Food (Green Means Go!)

Could a little red circle help you skip the comfort food this winter and maybe drop a few pounds? Doctors from Massachusetts General Hospital think so. They put traffic-light labels on their cafeteria's menu to signal the healthfulness of dishes. The colorful cues helped improve eating habits even two years later.

Arctic Methane Bubbles Not As Foreboding As Once Feared

European scientists were alarmed in 2008 when they discovered streams of methane bubbles erupting from the seafloor in Norway's high Arctic. This gas, which contributes to global warming, was apparently coming from methane ice on the seafloor. A follow-up study finds that methane bubble plumes at this location have probably been forming for a few thousand years, so they are not the result of human-induced climate change. But continued warming of ocean water can trigger more methane releases in the Arctic, with potentially serious consequences to the climate.

Looks Like The Paleo Diet Wasn't Always So Hot For Ancient Teeth

When hunter-gatherers started adding grains and starches to their diet, it brought about the "age of cavities." At least, that's what a lot of people thought. But it turns out that even before agriculture, what hunter-gatherers ate could rot their teeth. The problem: At least some of these ancients had a thing for acorns.

Oh Say, Can You See? A Musical Salute

You've heard it a thousand times, maybe 10,000. Is there any way to make "The Star-Spangled Banner" fresh? Even fascinating? There is (Jimi Hendrix aside). Here is a new one that did it for me — the Jon Batiste version.
