This undated image provided by NASA shows powdered rock in the scoop of the Mars rover Curiosity. The six-wheel rover collected the sample after drilling into a Martian rock. The next step is to transfer a portion to its onboard laboratories for analysis. Curiosity landed in August 2012 to study whether the environment was hospitable for microbes. (AP Photo/NASA)

In this photo taken Thursday, Jan. 24, 2013, in Chicago, brain surgeon Ali Alaraj talks about the first time he viewed the brain using the CAVE2. “You can walk between the blood vessels,” said the University of Illinois College of Medicine neurosurgeon. “You can look at the arteries from below. You can look at the arteries from the side".

Tests have found horsemeat in school meals, hospital food and restaurant dishes in Britain, as the scandal over adulterated meat spread beyond frozen supermarket products, and Britain's Environment Secretary Owen Paterson called for a Europe-wide overhaul of food testing in the wake of the ongoing horsemeat scandal.

Burnt trucks and tractors stand at a mining facility of Hellas Gold, near the village of Skouries, located on the northern peninsula of Halkidiki Greece, on Sunday, Feb. 17 2013. About 40 masked attackers raided the facilities of a prospective gold mine in northern Greece overnight Sunday, setting machinery and offices alight, authorities said. There has long been opposition to the prospect of a gold mine and processing plant being built at Skouries in the Halkidiki peninsula, with some residents objecting to what they say will be the destruction of the environment and of pristine forest in the area, leading to the loss of tourism and other local activities such as farming, the rearing of livestock and fishing.
