U.S. scientists have developed an on-off memory switch that helped laboratory rats remember a behavior they had forgotten. The brain prosthesis marks the first time scientists have been able to duplicate the brain's learning process, restoring memories that test rats were drugged to forget. This new research could help offer hope for people suffering from dementia. "Flip the switch on, and the rats remember. Flip it off, and the rats forget," Theodore Berger of the University of Southern...

What was thought to be lost is now found again. Two volunteer naturalists visiting a nature reserve in Colombia came across the mysterious guinea pig-sized rodent species, which scientists have thought to be extinct. Lizzie Noble and Simon McKeon, volunteers with the ProAves Foundation, were just about to turn in for the night on May 4, when the nocturnal red-crested tree rat stopped by for a visit. The rodent stayed for two hours, just watching as the volunteer biologists photograph it and...

Depression and anxiety may result from short-term digestive irritation early in life, according to a study of laboratory rats by researchers at the Stanford University School of Medicine. The findings suggest that some human psychological conditions may be the result, rather than the cause, of gastrointestinal disorders such as irritable bowel syndrome. "A lot of research has focused on understanding how the mind can influence the body," said Pankaj Pasricha, MD, professor and chief of...
