This is TALK OF THE NATION. I'm Neal Conan, in Washington. The doctor will see you now, words we've all heard many times, but more and more now doctors see their patients over a video link. For years, telemedicine has allowed doctors to treat patients anywhere, but as technology improves, new applications arise.

Yes, we talk a lot about eating bugs here at The Salt. We know, because some of you have complained about it.
Solved! A bee-buzzing, honey-licking 2,000-year-old mystery that begins here, with this beehive. Look at the honeycomb in the photo and ask yourself: (I know you've been wondering this all your life, but have been too shy to ask out loud ... ) Why is every cell in this honeycomb a hexagon?
Bees, after all, could build honeycombs from rectangles or squares or triangles ...
But for some reason, bees choose hexagons. Always hexagons.

For decades, scientists have believed our ancestors took up farming some 12,000 years ago because it was a more efficient way of getting food. But a growing body of research suggests that wasn't the case at all.
"We know that the first farmers were shorter, they were more prone to disease than the hunter-gatherers," says Samuel Bowles, the director of the Behavioral Sciences Program at the Santa Fe Institute in New Mexico, describing recent archaeological research.
Any gardener will tell you that compost is "black gold," essential to cultivating vigorous, flavorful crops. But it always feels like there's never enough, and its weight and bulk make it tough stuff to cart around.
I belong to a community garden in Washington, D.C., that can't get its hands on enough compost. So you can imagine my delight when I learned that the U.S. Composting Council was connecting community gardeners with free material from local facilities through its Million Tomato Compost Campaign.
Beekeepers In Massachusetts are taking the mission to save the bees into their own hands.
There has been a dramatic disappearance of honeybees across the U.S. since 2006. A recent U.S. Department of Agriculture report blamed a combination of problems, including mites, disease, poor nutrition and pesticides.
Mother's Day is upon us and I'm here to share some news with you. While there's nothing wrong with a well-chosen gift, recent research in psychology suggests your time might be better spent writing a well-crafted card to mom.
