Spade's arms went around her, holding her to him, muscles bulging through his blue sleeves.

That line comes from The Maltese Falcon and the guy with the blue sleeves is none other than Sam Spade. I read those words in a worn paperback copy my dad loaned me when I was 18 and I was quickly hooked. I'd fallen in love with the dark world of the noir detective. But who hasn't?

Telemedicine is nothing new, but advancements in technology have made it even more widely available. Neurologists can now treat Parkinson's patients from miles away, therapists can reach service members overseas, and general practitioners can work in rural areas without actually going there at all.

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.
