The hyper-local food trend is really big right now. And apparently, NASA wants to make sure astronauts don't miss out. The agency recently announced plans to grow cress, turnips and basil on the moon.

And to protect the plants from the harsh cosmic radiation and the moon's lack of atmosphere, NASA researchers will be sending them off inside a seriously high-tech terrarium.

Man Killed In Shark Attack Off Maui

Originally published on Tue December 3, 2013 3:35 pm

Yet another shark attack in Hawaii, this time leading to the death of a man off Maui. It comes just three days after a woman survived a harrowing shark attack on the same side of the island.

The Associated Press reports that a shark bit the dangling foot of Patrick Briney, 57, of Stevenson, Wash., as he fished from a kayak between Maui and Molokini, a small island that is a popular diving and snorkeling spot.

How To Keep The Dust Off Your White Pants With 7 Desk Fans

Once upon a time, you could crack open a radio, a telephone, a lawnmower, even a car, take it apart and figure out how it worked. No more. Pretty much everything we use these days comes with computer chips, which you can't really take apart. (I mean, you can, but all you'll find inside are a bunch of 1's and 0's with no obvious logic.) So car mechanics can snap a new chip into an engine, wait till it whirs and watch the gears come to life, but do they know what's going on in there? For most of us, chips are "black boxes." They work, but we don't know why.

Alleged Perils Of Left-Handedness Don't Always Hold Up

Lefties don't necessarily do everything with their left hand, and the ones who do might not use the right side of their brain for language.

I recently stumbled upon a description of research out of Yale that suggested there was a link between left-handedness and psychotic disorders like schizophrenia.

Forty percent of those with psychotic disorders are lefties, one of the researchers said. That startled me. Only about 10 percent of people in the general population are left-handed. I'm one of them.

I'm Not Just Gaming, Ma! I'm Helping The World's Farmers

Cropland Capture's developers hope players will find where crops are grown amid Earth's natural vegetation in satellite images to shine a light on where humanity grows its food.

There's no easy way to track all of the world's crops. What's missing, among other things, is an accurate map showing where they are.

But the people behind Geo-Wiki are hoping to fix that, with a game called Cropland Capture. They're turning people like you and me into data gatherers, or citizen scientists, to help identify cropland.

Saving The Native Prairie — One Black-Footed Ferret At A Time

Biologist Travis Livieri checks a briefly sedated ferret's health status inside an improvised trailer clinic.
Elizabeth Shogren NPR

American pioneers saw the endless stretches of grassland of the Great Plains as a place to produce grain and beef for a growing country. But one casualty was the native prairie ecosystem and animals that thrived only there.

Some biologists are trying to save the prairies and they've picked a hero to help them: the black-footed ferret. In trying to save this long skinny predator with a raccoon-like mask, the biologists believe they have a chance to right a wrong that nearly wiped a species off the planet.
