From southern Virginia to New England, lots of people are being treated to a cicada serenade. If these insects sound loud to you, that's because they are. They're so loud that some Navy engineers are trying to borrow their technique.
The origin of the first primates — the group that includes humans, apes and monkeys — is thought to lie in the deep past, about 55 million years ago.
Fossils from that period are rare. But now, there's an exciting new one. It's called Archicebus achilles, roughly meaning "beginning long-tailed monkey." Actually, this creature lived before the monkeys we know of today, a mere 10 million years after the dinosaurs died out.
This illustration shows the relative sizes of the habitable-zone planets Kepler-22b, Kepler-69c, Kepler-62e, Kepler-62f and the Earth.
Last week NASA scientists put the space telescope Kepler in a kind of technological coma. The craft, designed to search for Earth-like planets orbiting stars in our cosmic neighborhood (within a few thousand light-years, that is), failed and seems to be unfixable. (Hope remains, though.)
Scientists have figured out out how to turn cellulose from wood, bushes and grasses into edible starch.
For Percival Zhang, growing up in China meant learning to appreciate just how critical a stable food supply is to avoiding social unrest and disasters like famine.
When he became an associate professor of biological systems engineering at Virginia Tech, he got to thinking just how risky growing food has become because of the finite resources it requires: land, water, seeds and fertilizer.
Plenty of other plants on Earth, on the other hand, aren't so demanding.

If you're looking for the definitive study that might persuade meat lovers to become vegetarians, this may not be it.
New research published in JAMA Internal Medicine finds that vegetarian diets are linked to a slightly lower risk of early death — about 12 percent lower over a period of about six years of follow-up. But the link to longevity was more significant in men compared with women.

America has a problem. It's an existential problem, a big one that threatens our collective future. Our problem is the failing bond between science and the American people. Luckily for us all, it's a problem that can be solved. The solution? A big party! Well, that's not the solution, but celebrating science is one way to renew our community's bond with society.
This French tapestry depicts noblemen and women treading and pressing grapes to make wine circa 1500. By then, the French had already been making wine for at least 2,000 years.

The French weren't the first to make wine? Mon dieu! But as anyone who has sipped a Bordeaux, Champagne or Burgundy can tell you, the French got pretty good at it once they learned how. And thanks to some molecular archaeology, researchers can now confirm they picked up these skills as early as 425 B.C.
So who taught the French the art of viniculture? Probably the ancient Italians, says the man with perhaps the coolest nickname in science research — the "Indiana Jones of alcohol," Patrick McGovern.
Mississippi lawmakers have embarked on a controversial campaign to discourage older men from having sex with teenagers.
Starting in July, doctors and midwives in the state will be required by law to collect samples of umbilical cord blood from babies born to some girls under the age of 16. Officials will analyze the samples and try to identify the fathers through matches in the state's DNA database.
Some 3.5 million years ago, our ancestors put grass on the menu.
If you could travel back in time about 8 million years, you'd find a creature in an African tree that was the ancestor of all current apes and humans. And that creature in all likelihood would have spent a big part of its day munching leaves and fruit — pretty much what apes eat now.
