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).
And years after we first started talking about its departure.
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.
Satellite imagery and seismic data have identified two huge underground aquifers in Kenya's drought-prone north, a discovery that could be "a game changer" for the country, NPR's Gregory Warner reports.
The aquifers, located hundreds of feet underground in the Turkana region that borders Ethiopia and South Sudan, contain billions of gallons of water, according to UNESCO, which confirmed the existence of the subterranean lakes discovered with the help of a French company using technology originally designed to reveal oil deposits.

I noticed in The Guardian that there's a book coming out this week listing the 20 biggest challenges for modern science. I'd like to go over 10 of them today, perhaps coming back to the other 10 next week.
When I saw it for the first time, here's what I knew: It's a Google image found on Google Maps, taken by a satellite, plucked and blogged by photographer/sleuth, Mishka Henner. It's a patch of land near a town called Coevorden, in The Netherlands. There's a road on one side, plowed farmland all about, some trees on the lower left and then, weirdly, grey, black, white, golden, green and brown patches crunched together in an almost-rectangle. Those couldn't be natural, I thought.
Lauren Henderson goes everywhere with her service dog Phoebe — to the grocery store, Disneyland, the beach. For Henderson, who used to be paralyzed, her 100 pound, lumbering Saint Bernard is a necessity.
An actor who lives in Malibu, Calif., Henderson uses her dog for stability and balance. And if she falls, Phoebe helps pull her back on her feet.
"She's basically like a living walker," Henderson says.
