Deleting Certain Gene Makes Mice Smarter 259

An anonymous reader writes "Deleting a certain gene in mice can make them smarter by unlocking a mysterious region of the brain considered to be relatively inflexible, scientists at Emory University School of Medicine have found. Mice with a disabled RGS14 gene are able to remember objects they'd explored and learn to navigate mazes better than regular mice, suggesting that RGS14's presence limits some forms of learning and memory."

Researchers Restore Youthful Memory In Aging Mice 145

An anonymous reader writes "German neuroscientists made a breakthrough in 'age-related cognitive decline', a common condition that often begins in one's late 40s (especially declarative memory — the ability to recall facts and experiences). Their new study identifies a genetic 'switch' for the cluster of learning and memory genes that cause memory impairment in aging mice. By injecting an enzyme, the team 'flipped' the switch to its on position for older mice, giving them the memory and learning performance they'd enjoyed when they were young. Now the team ultimately hopes to recover seemingly lost long-term memory in human patients." The video, which explains the gene flipping mechanism, is worth a watch (2:18).
