Darkness Provides A Fix For Kittens With Bad Vision

Scientists found that darkness worked far better than they expected as a treatment for kittens with lazy eye.

When it comes to treating a lazy eye, there's evidence that turning the lights off may help — if you're a kitten.

A study in the latest issue of Current Biology reports that kittens with a type of visual impairment known as amblyopia, or lazy eye, were able to regain normal eyesight after being plunged into total darkness for 10 days.

With Brawls And Calls, Love Is In The Air For Elephant Seals

On this Valentine's Day, we bring you a story from the California coast, where love is in the air. It sounds something like this:

That's a male northern elephant seal. It's the peak of their mating season right now. Elephant seals spend of the most of the year alone, out in the Pacific Ocean. So you can probably guess what happens when they get together every winter.

Naturalist Lisa Wolfklain is leading a public tour at Ano Nuevo State Reserve, two hours south of San Francisco, where hundreds of elephant seals are packed together on a narrow strip of beach.

Traces Of Anxiety Drugs May Make Fish Act Funny

Many of the drugs we take aren't actually digested — they pass through our bodies, and down through the sewer pipes. Traces of those drugs end up in the bodies of fish and other wildlife. Nobody's sure what effect they have.

Now, a paper being published in Science magazine finds that drugs for anxiety drugs — even at these very low levels — can affect the behavior of fish.

When Resistance Is Futile: Bring In The Robots To Pull Superweeds

A future without weeds would be a kind of farmer utopia, but currently, herbicide-resistant "superweeds" are part of today's reality. Some researchers, though, are looking for a solution that seems ripped from science fiction: weed-seeking robots.

Scientists Pass The Hat For Research Funding

Car commercial? Nope. Jessica Richman, Zachary Apte (center) and William Ludington are looking to the crowd for money to fund uBiome, which will sequence the genetic code of microbes that live on and inside humans.

When the X-ray was invented, people clamored to get one. Not for any medical reason, but just to see what was typically hidden inside their bodies.

Something like that seems to be happening with DNA sequencing technology. First it was companies offering to sequence people's genomes. Now it's learning all about your microbiome, the collection of microorganisms living on and in your body.

What do you do when you're a scientist and you have no job and no money for your research? If you're Ethan Perlstein, you try crowd funding. He raised $25,000 to investigate where the drug methamphetamine is stored in the brain.

Marine Stewardship Council Responds To NPR Series On Sustainable Seafood

Swordfish from Canada feature a label from the Marine Stewardship Council at a Whole Foods in Washington, D.C.
Margot Williams NPR

Originally published on Wed February 13, 2013 2:32 pm

Earlier this week, NPR aired a three-part investigation of the Marine Stewardship Council on Morning Edition and All Things Considered.

As Daniel Zwerdling and Margot Williams reported, the MSC certifies seafood that is supposed to be good for the environment. But some environmental groups argue that the label is misleading, and that as more retailers promise to sell only sustainable-labeled seafood, the program is certifying fisheries that don't deserve it.

Did North Korea Test A 'Miniature' Nuclear Bomb?

North Korea's latest nuclear weapons test is much more powerful than the previous two, according to estimates made by instruments that measure seismic waves from the blast. It's about the size of the bomb that devastated Hiroshima in World War II.

But it's not so easy to verify the claim that the nuclear explosive has also been miniaturized. That's a critical claim because a small warhead would be essential if the rogue regime chose to threaten the United States with a nuclear-tipped missile.

Big bombs are easier to make, but they aren't all that useful as a threat.
