Brain enzyme helps keep memory sharp in old age
Researchers in Boston have discovered an enzyme that the brain itself makes more of as we get older, and that seems to protect memory. In old mice, an extra dose kept memory in better shape. The next step is to find out whether this can also be done safely in humans.

Blood cells from an 80-year-old become young brain stem cells in the lab
Researchers in Bonn have directly converted blood cells from an 80-year-old into neural stem cells with a molecular age of under 20. The rejuvenation happened gradually, and that is exactly what makes it a useful model for unravelling how cells become younger.
