NASA has decided to go ahead with a series of spacewalks to fix a broken cooling system aboard the International Space Station.

The decision was made Tuesday by station managers. They said the extra-vehicular activity should take place as soon as possible to replace a coolant pump that contains a bad valve.

The Associated Press says:

"The spacewalks are taking priority over the launch of a supply ship from Virginia. The delivery had been scheduled for this week, but is now delayed until January."

Industrial Meat Bad, Small Farm Good? It's Not So Simple

Somali refugees lead their herds of goats home for the night outside Dadaab, Kenya. A new study shows that animals in many parts of the developing world require more food — and generate more greenhouse emissions — than animals in wealthy countries.

To feed all 7 billion of us, address climate change and live longer, we all need to eat less meat. From Al Gore to the Meatless Monday movement to Harvard epidemiologists, that's been the resounding advice offered to consumers lately.

The brown marmorated stink bug doesn't just smell bad. It's also been causing trouble for homeowners and farmers from New Hampshire to California for the past three years.

No predators are eating the invasive species fast enough to keep it under control, but researchers think they may have found a solution to the stink-bug menace.

Oldsters, it turns out, matter. They matter a lot. And not just in human families. I've been reading a new book called The Once and Future World, by J. B. MacKinnon, which points out that when we humans hunt game, when we fish the sea, we often prize the biggest animals because they have the biggest tusks, or the most protein, so they're the ones we kill first.

Environmentalists Split Over Need For Nuclear Power

Southern California's San Onofre Nuclear Generating Station, shown here in April 2012, was closed after small radiation leaks.

California is regarded as the leading state when it comes to addressing climate change. But in 2012, according to analysts at Rhodium Group, California's carbon emissions actually increased more than 10 percent, bucking the national trend of decreases. That's in large part because California shut down one of its few remaining nuclear power plants.

That rise in carbon emissions underscores the huge impact nuclear power can have in efforts to combat climate change.

Scientists Find Tiny Exfoliating Beads In Great Lakes Fish Guts

Originally published on Mon December 16, 2013 8:06 pm

Tiny plastic beads used in some cosmetics and toothpaste are making their way into the bellies of fish in the Great Lakes, and it's raising concern among environmentalists. Dr. Sherri Mason, a chemistry professor at the State University of New York at Fredonia, has been researching the issue, and she joins Audie Cornish to explain what this means for the Great Lakes ecosystem.

There's no such thing as too much practice when it comes to brain surgery.

But it's hard for beginner neurosurgeons to get real hands-on experience. Most residents learn by watching and assisting experienced surgeons.

What's That Clinging To The Towering Wall And Why Doesn't It Fall Off?

Maybe you've seen this, (it's gotten around), but I'm still gobsmacked. Totally amazed. We're in northern Italy looking at the face of the Cingino Dam, and here and there on the vertical stone wall, you'll see a few dark specks.
