Doomsday Scenarios: 13 Ways the World Could End Today

"One nuclear bomb can ruin your whole day." It was true back in the late 1950s, and it's just as true now. The world could end at any moment thanks to the countless nukes out there, just lying around. According to a 2010 Ploughshares Fund report, 22,000 active nuclear warheads are scattered around the globe. And that number doesn't include smaller—and therefore more susceptible to theft—nuclear weapons like atomic artillery shells and bunker busters. In truth, we're still exactly where we've been for the past 70 years: one international argument away from the end of the world.

10 Bizarre Medical Treatments Involving Animals

Humans have long depended on the natural world as the source of our most powerful treatments, from the use of sheep-gut thread to sew wounds up in ancient times, to the bacteria-killing properties of penicillin discovered in the first half of the 20th century. Yet, whether everyday or downright disgusting, some of these remedies can be pretty surprising to Western eyes. In Cambodia, for instance, cattle are sacred animals, and itÕs apparently considered quite healthy to drink cow urine. And, unbelievably enough, the techniques used for modern heart and lung transplants were partly inspired by Soviet experiments in creating two-headed dogs during the 1950s. We list our top ten strangest medical treatments involving animals.

The Top 20 Whitest Musicians of All Time

Considering that most all of today's popular music -- be it rock, pop, dance or rap -- sprang from genres pioneered by black musicians, being all Caucasian about your songs is to literally betray your roots. To qualify as one of our whitest musicians, then, requires more than a pasty complexion, it requires a near-total disregard for jazz, blues and soul or, even worse, a complete whitewashing of them. Without further ado, then, here are 20 performers who put the you-know-what in honky-tonk.

10 Incredible Airplane Designs of the Future

NASA awarded three contracts this fall for designs of aircraft that will be flying in 2025 to Boeing, Northrup Grumman and Lockheed Martin. Each one has to be less noisy, more fuel efficient and have cleaner exhaust than planes flying now. Other specifications by NASA are that they should "fly up to 85 percent of the speed of sound; cover a range of approximately 7,000 miles; and carry between 50,000 and 100,000 pounds of payload, either passengers or cargo." Here are the three concept designs as well as some from April and earlier. Not all of them will make it beyond the design stage and some may have already been scrapped, while others could be very close to being seen on our runways in the future.

10 of America's Best Lake Vacations

Waking to another cloudless morning, you dive off your houseboat into the wild blue of Lake Powell in southern Utah. The water takes the edge off the heat, and you float along, contemplating a lazy day of navigating spectacular red-rock gorges and flooded canyons. Brian Raub, founder of, says lakes have an inherent advantage over the ocean when it comes to vacations. "You'll probably prefer the feel of freshwater over salt, and you probably won't miss seasickness, seaweed or sharks. You can choose your outdoor temperatures; lakes exist at elevations from below sea level to 13,000 feet above." And temperature isn't your only choice: America offers a lake vacation for every season and activity, and no matter where you live, even in the Southwest desert, chances are there's one near you. Satellite mapping has yet to yield a precise answer, but the best guess is that there are between 3 and 4 million lakes across the U.S., ranging from duck ponds to wonders like Oregon's Crater Lake.
