Look into the light - unless you want to keep your memories.

UC Davis psychologists have used light to erase specific memories in mice and proved a basic hypothesis fpr how different parts of the brain work together to retrieve episodic memories. Optogenetics, created by Karl Diesseroth at Stanford University, is an effort at manipulating and studying nerve cells using light. The techniques of optogenetics are becoming popular for brain function studies.

An international team has retrieved antiquities including tableware, ship components, and a giant bronze spear that would have belonged to a life-sized warrior statue from an ancient Greek ship that sank more than 2,000 years ago off the remote island of Antikythera.

The Antikythera wreck was first discovered in 1900 by sponge divers who were blown off course by a storm. They subsequently recovered a haul of ancient treasure including bronze and marble statues, jewelry, furniture, luxury glassware, and the surprisingly complex Antikythera Mechanism. But they were forced to end their mission at the 55-meter-deep site after one diver died of the bends and two were paralyzed.

Onions consistently make the lists of organic foods even the most ardent organic advocates don't recommend paying the extra money for; they have so many layers of skin that no pesticide, organic or synthetic, is getting through.

But it's still a market as long as people are willing to pay for a special sticker. And if you are in that market, there is good news; a new study of herbicides derived from clove oil tested the natural products' effectiveness in controlling weeds in Vidalia® sweet onion crops. Vidalia® sweet onion is a dry bulb onion grown in Georgia as a cool-season (winter) crop. 

America now has a services funding problem that has plagued Europe for a time - nowhere near enough workers to pay for people getting government money. 

Though there are now 2 workers to pay for Baby Boomer social security, compared to 42 when the system started, a new study advocates even fewer babies and more economic slowdown. But it will pay off, say scholars from the University of California, Berkeley and the East-West Center in Hawaii.

A high amount of methane, the main component of natural gas, is escaping from the Four Corners region in the U.S. Southwest, according to a new study.

A team of scientists using NASA's Hubble Space Telescope to make the most detailed global map yet of the glow from a giant, oddball planet orbiting another star, an object twice as massive as Jupiter and hot enough to melt steel, called WASP-43b.

WASP-43b is a world of extremes, where winds howl at the speed of sound from a 3,000-degree-Fahrenheit dayside to a pitch-black nightside when temperatures plunge to a relatively cool 1,000 degrees Fahrenheit, still hot enough to melt silver.
