In a recent study, scientists delivered a molecule called FKBP1b into the central memory station found in the brain of aging rats. Upon administrating the molecule, hundreds of formally active genes were reactivated, in a pattern that closely resembles those of younger, more mentally agile rats than aged ones. As a result, the rats showed enhanced learning and appeared to reverse memory shortfalls when tackling a maze. These findings suggest that the mental rustiness which accompanies aging happens because the amount of this one molecule goes down; a follow up study is currently in the works to see why that is.
