If you're finding it harder to remember where you put the car keys, the culprit could be a brain protein with a name that's easy to forget: RbAp48.
A shortage of this protein appears to impair our ability to remember things as we age, researchers report in the current issue of Science Translational Medicine. And boosting levels of RbAP48 in aging brains can reverse memory loss, at least in mice, they say.
I don't remember when I first realized that books could go away, that they could — and did — pass into obscurity or out of print. Myra Breckinridge by Gore Vidal, AllAbout H. Hatterr by G.V. Desani, Speedboat by Renata Adler, the sublime An Armful of Warm Girl by W.M. Spackman. Each of them, snuffed out. It seemed a scandal. But I vividly recall becoming aware that particular books were prone. To take chances with language or form was to court extinction.
