While milk consumption continues to fall in the U.S., sales of organic milk are on the rise. And now organic milk accounts for about 4 percent of total fluid milk consumption.

For years, organic producers have claimed their milk is nutritionally superior to regular milk. Specifically, they say that because their cows spend a lot more time out on pasture, munching on grasses and legumes rich in omega-3 fatty acids, the animals' milk is higher in these healthy fats, which are linked to a reduced risk of heart disease.

Avery Stackhouse, age 7, of Lafayette, Calif., says he wishes he had more time for phys ed.

"We just have it one day a week — on Monday." There's always lunch and recess, he says. "We play a couple of games, like football and soccer," he tells Shots.

But at Happy Valley Elementary, where he goes to school, recess lasts only 15 minutes and lunch is 45. Between eating and mingling, he says, "there's only a few minutes left where we play games and all that."

Microbiome Candy: Could A Probiotic Mint Help Prevent Cavities?

A sweet way to avoid the dentist? Microbiologists are developing a probiotic mint that uses dead bacteria to fight off cavities.
Morgan Walker NPR

Eat candy and fight tooth decay. What a sweet concept, right?

Well, microbiologists in Berlin are trying to make that dream a reality.

They've created a sugarless mint that's aimed at washing out cavity-causing bacteria from your mouth. And the candy works in a curious way: It's spiked with dead bacteria. It's like probiotics for your teeth.

The experimental mint is still in the early days of development — and far from reaching the shelves at Walgreens.

What Happened On Easter Island — A New (Even Scarier) Scenario

We all know the story, or think we do.

Let me tell it the old way, then the new way. See which worries you most.

First version: Easter Island is a small 63-square-mile patch of land — more than a thousand miles from the next inhabited spot in the Pacific Ocean. In A.D. 1200 (or thereabouts), a small group of Polynesians — it might have been a single family — made their way there, settled in and began to farm. When they arrived, the place was covered with trees — as many as 16 million of them, some towering 100 feet high.

The track record of commercial products designed with privacy as a top priority has been abysmal — at least until recently. The ephemeral texting app Snapchat is turning assumptions upside down about young people and their desire for digital privacy.

Fred Cate, director of applied cybersecurity research at Indiana University, is an expert on privacy in the digital age. But when it comes to the viability of tech products that promise privacy, Cate has always been skeptical.
