Epigenetic celebrity

A few years ago, researchers like McGill's Moshe Szyf were scoffed at for their ideas. Today Szyf, a professor of pharmacology at McGill, and a few others are mini-celebrities in the increasingly accepted field of epigenetics. The study of epigenetics postulates that there is a "second code" of programming on top of our DNA, a code that -- unlike DNA -- can change during our lifetimes.
