Stem cell injections improve spinal injuries in rats Posted: 27 May 2013 08:18 PM PDT Scientists report that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury.

Formula for turning cement into 'metal' Posted: 27 May 2013 12:37 PM PDT In a move that would make the alchemists of King Arthur's time green with envy, scientists have unraveled the formula for turning liquid cement into liquid metal. This makes cement a semi-conductor and opens up its use in the profitable consumer electronics marketplace for thin films, protective coatings, and computer chips.

Scientists find mechanism that causes noise-induced tinnitus and drug that can prevent it Posted: 27 May 2013 12:37 PM PDT An epilepsy drug shows promise in an animal model at preventing tinnitus from developing after exposure to loud noise, according to a new study. The findings reveal for the first time the reason the chronic and sometimes debilitating condition occurs.

Rats have a double view of the world Posted: 27 May 2013 07:05 AM PDT Scientists using miniaturised high-speed cameras and high-speed behavioural tracking have discovered that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running around. Each eye moves in a different direction, depending on the change in the animal's head position. An analysis of both eyes' field of view found that the eye movements exclude the possibility that rats fuse the visual information into a single image like humans do. Instead, the eyes move in such a way that enables the space above them to be permanently in view -- presumably an adaptation to help them deal with the major threat from predatory birds that rodents face in their natural environment.

Preterm birth affects ability to solve complex cognitive tasks: Too early to learn Posted: 27 May 2013 07:04 AM PDT Being born preterm goes hand in hand with an increased risk for neuro-cognitive deficits. Psychologists from the Ruhr-Universität Bochum and the University of Warwick, UK have investigated the relation between the duration of pregnancy and cognitive abilities under varying work load conditions.
