Pop the Popcorn Now

Set your TiVos. Tonight's NOVA scienceNOW, airing at 9pm Eastern, looks into personal genetic testing. The preview to the episode says Harvard's Steven Pinker took a genetic test that told him he had an 80 percent risk of being bald — Pinker's hair is a cross between Mozart and Einstein — and now he's part of the PGP that will be posting their DNA sequences on the Internet. If you can't catch it tonight and haven't succumbed to getting a digital recorder, you can watch the program tomorrow at PBS's website.
