Colorado Vault Is Fort Knox For The World's Seeds

Dave Dierig, research leader at the National Center for Genetic Resources Preservation, stands among the ceiling-high shelves that hold the 600,000 seed packets in this cold storage vault.

When unapproved genetically modified wheat was found growing in Oregon earlier this year, it didn't take long for accusations to start flying. A flurry of initial finger-pointing cast potential blame on a federal seed vault in Fort Collins, Colo., which housed the same strain of wheat, developed by Monsanto Corp., for about seven years up until late 2011.

AUDIE CORNISH, HOST:

Occasionally, when it's a slow news day, we wind up with holes in the show; gaps of a minute or two that the news of the day doesn't quite fill.

NPR science correspondent Joe Palca offered to fill those with science stories about holes.

It's bad enough to have to be tested for dementia. It's even worse if the test isn't fair. Researchers in Chicago found they needed to update the screening test for a type of early onset dementia so that the measure would more accurately pick up symptoms among a new wave of patients — baby boomers and Gen Xers.

"It's a very curious time in high-energy physics," says Michael Peskin, a researcher at SLAC National Accelerator Laboratory in California. On the one hand, researchers have just made the most significant discovery in decades: In July of last year, they announced they had found the Higgs particle at a collider in Switzerland. The Higgs is part of the mechanism that gives mass to everything. It is so fundamental that without it, we wouldn't exist.

Brains Of Dying Rats Yield Clues About Near-Death Experiences

Could the images common in accounts of near-death experiences be explained by a rush of electrical activity in the brain?

A burst of brain activity just after the heart stops may be the cause of so-called near-death experiences, scientists say.

The insight comes from research involving nine lab rats whose brains were analyzed as they were being euthanized. Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness.

Although the experiment relied on animals, the results could apply to humans, too, the researchers say.
