Workers at Japan's Fukushima Dai-Ichi nuclear power station successfully completed the first day of a delicate operation to remove radioactive fuel rods from a reactor damaged in the March 2011 tsunami.
The fuel rods were removed from the Unit 4 reactor, which was offline at the time the tsunami smashed into the plant, overwhelming its backup systems. Although Unit 4 was spared the fate of three other reactors that melted down, a fire in its containment building weakened the structure.
NASA's MAVEN explorer blasted off Monday on the first leg of its 440-million-mile journey to Mars, where scientists hope it will answer an ancient question: why the red planet went from warm and wet to cold and dry in a matter of just a billion years.
The robot orbiter, called the Mars Atmosphere and Volatile Evolution probe, launched aboard an Atlas V rocket from Cape Canaveral Air Force Station at 1:28 p.m. EST. It will take 10 months to reach Mars.
There's something deeply compelling about "seeing" the mind at work with the help of relatively new neuroscientific tools, such as functional Magnetic Resonance Imaging (fMRI), which furnish the images of brain activation that often accompany popular science coverage. Indeed, a well-known 2008 paper by McCabe and Castel reported that people thought articles containing fMRI images of the brain reflected better scientific reasoning than matched articles that did not.

Imagine a tiny computer embedded under your scalp that's constantly tracking your brain activity and zapping you when it senses something awry.
That might sound like science fiction, but a medical device that does that was just approved by the Food and Drug Administration as an option for people with epilepsy that's resistant to treatment with drugs.
One thousand calories, vitamins and minerals, 13 grams of fat every day. Those are the specific ingredients needed to avoid stunting a child's growth physically and mentally in the 1,000 days after conception. New research from the International Food Policy Research Institute looks at the economic rationale for investing in those first few years.
And senior researcher, John Hoddinott, explains some of the consequences for undernourished children in the world's poorest countries.
OK. So, let's say you're at work. Someone comes up while you're doing something else and says, hey, did you get that e-mail I sent you yet? And you have no idea what they're talking about, so you spin around and say, huh? But what if you were in Spain?
UNIDENTIFIED MAN #1: Eh?
GONYEA: Or Ghana?
UNIDENTIFIED MAN #2: Ah?
GONYEA: Or Laos?
UNIDENTIFIED MAN #3: Heh?
GONYEA: Turns out, anywhere really, there's some form of the word huh?
The Environmental Protection Agency today proposed to scale back the amount of renewable fuels in our nation's gasoline supply, biofuels like ethanol made from corn. The EPA is responding, in part, to oil companies that say they're already taking as much ethanol as they can. They say any more and it will hurt quality. But there's another reason for the EPA's action. As NPR's Elizabeth Shogren reports, cheap biofuels haven't been developed as quickly as hoped.
