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.

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.
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.

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.

Judy Van der Veer is an American author (1912-1982) who wrote books that are too little remembered now. In her works of fiction and non-fiction, Van der Veer beautifully brings alive small California worlds close to nature.
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.

Of all the patriarchs of science, Johannes Kepler is the least known. We often talk of Isaac Newton and his law of universal gravity (and laws of motion, and the calculus, and laws of optics), of Galileo's impetuosity and his telescopic discoveries (and law of free fall and pendular motion), and of Copernicus, the man who put the sun in the center of the cosmos. But Kepler? Sounds familiar; but what was it again?

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.
