If you've ever shopped at Whole Foods, you've probably noticed that some of the foods it sells claim all kinds of health and environmental virtues.

Treat Yourself To A 'Huh?'

Robert Krulwich NPR

You drop a ball. You drop a key. You drop a piece of lead. They each slip from your hand and tumble to the ground. But you have an orderly mind (you're a physicist) and, to you, falling things don't seem haphazard — they seem neat. The unruly world has rules, laws. So instead of saying "Bummer!" you say, "Of course! How beautiful! How logical!"

Couch potatoes everywhere, rejoice.

New commercial devices, using technology borrowed from the field of neuroscience, are making it possible to control objects with brain power alone. The idea is to help train users to become more focused — and relaxed.

EEG headsets, which detect electrical activity in the brain, were once found only in research labs. Today, the technology has become cheaper and easier to use. That's made it possible to connect EEG headsets to other consumer devices.

Want to get away? Thinking about a place with warm water and soft sand? Sounds nice. But think twice before you wade into that inviting surf. Chances are there are stingrays in the area.

Every year, these timid, shellfish-eating cousins of the shark inflict excruciating injuries on thousands of swimmers and surfers from the Bahamas to Bahrain to both coasts of the United States.

... That's the message received from a bleary-eyed comet-chasing space probe on Monday, much to the relief of ground-based controllers who sent it a long distance wake-up call after nearly a three-year nap.

The European Space Agency received the communique from deep space on schedule at 1 p.m. ET from Rosetta, some 500 million miles away on a trajectory to rendezvous with comet 67P/Churyumov-Gerasimenko in August. It's been in sleep mode to conserve power.

"I don't know why you're on Mars, but whatever the reason for going to Mars is, I'm glad you're there and I wish I was with you."

That was a part of astrophysicist Carl Sagan's message, recorded a few months before he died in 1996, to the future human inhabitants of Mars.

Some of the earliest science fiction imagined voyages to the Red Planet. We now have the space-faring technology, and getting humans to Mars actually seems within reach. It would certainly involve massive resources and a lot of danger, but some believe the rewards would be massive.
