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.

Like other animals and many living things, we humans grow when we're young and then stop growing once we mature. But trees, it turns out, are an exception to this general rule. In fact, scientists have discovered that trees grow faster the older they get.

The nation's capital is not exactly a beach town. But the cherry-tree-lined Tidal Basin, fed by the Potomac River, laps at the steps of the Jefferson Memorial. And, especially since Superstorm Sandy, officials in Washington have a clear idea of what would happen in a worst-case storm scenario.
"The water would go across the World War II memorial, come up 17th Street," says Tony Vidal of the U.S. Army Corps of Engineers. "And there are actually three spots where the water would come up where we don't have ... a closure structure right now."
