Slate just conducted an interesting experiment in Orwellian-style rewriting of history. Readers were asked to share their their recollections of recent historical events, many of which never actually happened. That didn’t matter…

German neuroscientists have made a breakthrough in “age-related cognitive decline” which often begins in your 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 which 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.
