Organic milk contains about 62 percent more omega-3s than milk from cows on conventional dairy farms, a new U.S.-based study finds. To get the full boost of these healthful fatty acids, you'll need to drink whole milk.
An NPR poll finds that most elementary school kids have physical education classes just one or two days a week. In response, parents and educators are getting kids to squeeze in walks, jogs and jumping jacks before, after and even during school.
Lacing a sugar-free candy with the right kind of bacteria might one day help fight off tooth decay, a study suggests. The experimental mint lowered the levels of cavity-causing bacteria in volunteers' saliva. But the microbe candy still has a long way to go before it reaches shelves at Walgreens.
December 8, 2013 For the first time, scientists have figured out where we sit on the global food chain. Although humans are clearly top chefs of the world, we're not the top predator. Instead, our ranking is closer to a small, smelly fish that we put on pizzas and salads.
December 6, 2013 That difference translates to about $550 a year, according to a new meta-analysis of studies evaluating the retail costs of food, grouped by healthfulness. It's chump change for middle-class eaters, but a big gap for low-income families. Researchers say that's a problem that can be solved.
December 6, 2013 The only person known to have been cured of AIDS got a bone marrow transplant, so when two AIDS patients in Boston appeared to be free of the virus after transplants, scientists hoped they were cured, too. But the HIV virus has returned in both.
December 3, 2013 The space agency has announced plans to grow turnips, basil and cress on the moon by 2015. The experiment could be good news for astronauts sick of their freeze-dried fare. But researchers say the real goal is to see if humans could one day live — and farm — on the moon.
December 3, 2013 To forecast sudden global catastrophe — and, perhaps, head it off — we should be spying on the climate at least as closely as we spy on each other, an expert panel warns. Yet the primary global monitoring network has been cut by 30 percent.
November 28, 2013 Scientists have identified special cells in the brain's hippocampus that mimic a trick of some digital cameras. These cells automatically 'tag' the memory of each event in our lives with information about where that event took place — the better to recall, perhaps, where we left our lost keys.
November 26, 2013 So you know how, if someone comes by and taps the top of your open beer bottle, a volcano of brewski will explode? Well, it turns out that the physics involved are the same as what causes an atomic bomb to form a mushroom cloud. A scientist explains how it works.
