At least two waterspouts were seen over Lake Michigan on Thursday, near the Wisconsin border, amid strong winds and a marine warning issued by the National Weather Service.
The Associated Press says the waterspouts — tornadoes that form over the water — merged into one and then split again. The video below, taken by an amateur in Pleasant Prairie, Wis., appears to be a single, merged, waterspout:
NASA's two Voyager spacecraft, launched in 1977, have made history in a dramatic fashion by exploring the outer planets: Jupiter, Saturn, Uranus and Neptune. Now one of the vehicles, Voyager I, has made another pioneering leap. It is the first spacecraft to leave the vast bubble of hot gas that surrounds our solar system.
At long last, Voyager 1 is now in interstellar space.

Stop us if you've heard this one: A spacecraft flies out of the solar system ...
Yes, the planetary probe Voyager 1, launched in the era of Jimmy Carter and bell-bottoms, has finally left the room, so to speak, years after completing its primary mission: a "grand tour" of the gas giants Jupiter and Saturn (twin Voyager 2 also visited Uranus and Neptune).

The latest spate of computerized watches promise to do everything from working as a phone to taking photos and fielding emails. Smart watches have actually been around for a long time, but they've never really taken off as a product.
Perhaps one of the most uncomfortable things a doctor has to tell patients is that their medical problems are iatrogenic. What that means is they were caused by a doctor in the course of the treatment.
Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable. Now, a medical researcher in Seattle thinks he has a way to eliminate some of the inevitable ones.

North Korea appears to be in the process of restarting a nuclear reactor used to produce weapons-grade plutonium, five years after shutting the facility down as part of international disarmament efforts.
New satellite imagery appears to reveal that the 5-megawatt reactor at Yongbyon, which experts believe can produce enough plutonium for one to two bombs a year, shows signs of being operational.
