Experimental drug reverses age-related memory loss

This sounds promising: a new drug developed by researchers at the University of Edinburgh has been proven to reverse age-related memory loss in mice, and it may make the jump to human subjects.
The drug works by blocking an enzyme called 11 beta-hydroxysteroid dehydrogenase type 1 generates glucocorticoids, a class of hormones. When those enzymes are inhibited by the drugs, it only took 10 days of treatment to improve the memory of elderly mice.
Of course, it's going to take some time to figure out whether or not this will work in people, but it sure sounds exciting.
