Finally, after over a century of debate, scientists seem to have answered the thorny question of sex, and, specifically, why.

Last week, Brazilian authorities confirmed the existence of an uncontacted tribe of about 200 in the Western Amazon. They may be the last people on Earth unaware of the whole Charlie Sheen thing. (His existence, that is.)

Divers off the coast of North Carolina recovered the third-largest anchor from what's believed to be the remains of the pirate Blackbeard's ship, Queen Anne's Revenge. It's 11 feet and four inches long (seven feet, seven inches wide), and covered — as you can see — with gross ocean stuff. No word on whether or not it's haunted.

Pyramids, being rather large, are not really the kinds of things one expects to be lost easily. And yet! Seventeen new (well, not "new," but) pyramids have been identified through the use of satellite imaging, which can see underground.

Scientists who study islands have apparently been sleeping on the job for years, because get this: Researchers have discovered 657 new islands around the world, making for a grand total of 2,149.

What is happening in the field of paleontology, these days? Oh, not much. Besides finding the actual bones of the Easter Bunny on its ancient island kingdom of Minorca, that is!

Italian paleoanthopologist Marco Peresani found a bunch of bird bones in the "Grotto of Smoke," a site known for being "loaded with Neanderthal bones." And he's got a theory: They wore them! As accessories! Fashion!!

Poor Comic Sans! The favorite font of administrative assistants and H.R. representatives everywhere is deeply hated by so-called "design nerds." But guess what, design nerds? Poor unpopular Comic Sans might actually have a beneficial use. Because it's so horrifically ugly.

Scientists finally took some pictures of "Hanny's Voorwerp," the "bizarre," galaxy-sized space blob discovered by a Dutch school teacher in 2007, and it turns out it's "giving birth" to "very lonely newborn stars." Better than "eating planets," I suppose.

A group of scientists believe they've figured out the "root cause" (ha ha) of male pattern baldness. It's witchcraft! No, actually, it's stem cells. And if you want to get rich off a "cure" for baldness, you'd better get cracking.

This is how you know you're rich: When you are the kind of person who has a "private collection" that includes the severed head of Henri IV, the former King of France. Apparently, there are several such people.

Archaeologists in China have dug up what they believe is a 2,400-year-old bowl of bone soup, as well as a pot of wine, near China's former capital Xian.

Are you familiar with "hobbits," or Homo florsiensis, the wee, extinct human species thought to have lived tens of thousands of years ago? Are you aware that they might have been hunted and eaten by enormous, six-foot-tall storks?

The bodies of two American balloonists, missing since September, were found inside the balloon's gondola by fishermen in the Adriatic Sea today.

A group of researchers was able to reverse the aging process in genetically-altered mice, "dramatically" regenerating their organs and restoring neurons to their brains. Next stop: Eternal life! Which almost sounds worse, to be honest.

Scientists say they've found oxygen in the atmosphere of Rhea, one of Saturn's moons—the first time there's been direct evidence of oxygen on another world. It's not enough to sustain life, but my lease is up soon, so...

Scientists have found a new species of monkey in northeast Burma, which they have named the Burmese snub-nosed (Rhinopithecus strykeri). Local hunters provided them with skulls and skin, leading to the find. Scientists estimate the population numbers 260-330 monkeys.

This painting of Jesus and Mary might be a lost, unfinished Michelangelo. So it's odd that it's spent the last few decades bundled up behind the couch in the Buffalo, New York home of the Kober family.

Astronomers have discovered a possibly Earth-like—and therefore possibly liveable—planet in a star system 20 light years away, which is pretty close, in galactic terms. But can we all move to that planet when we've finished destroying this one?

Most guys have probably guessed that mainstream clothing companies are a little bit... generous with their measurements. But they probably haven't guessed how generous. The Dockers 36-inch waist? Actually 39.5 inches around. And they're not even the worst offenders.
