The Year in Medicine 2008
In good times and bad, science doesn't sleep, and every year brings breakthroughs, setbacks, reasons for worry and reasons for joy. TIME's annual alphabetical roundup of a sampling of those stories gives you an overview of the year behind and a hint of what might be in the one ahead.
Fertility: Women's Voices and Ovulation
Listen up, especially if you're thinking of having a child: a UCLA study has shown that women's voices get higher (and more alluringly feminine) as ovulation (and increased fertility) approaches. Researchers recorded the voices of 69 women during high- and low-fertility phases and found that as fecundity climbs, so does pitch. Surprisingly, voice changes occurred only when the women spoke an introductory sentence ("Hi, I'm a student at UCLA") and not when they pronounced vowels. This could suggest that the variation happens just when people are conveying a message, and so it's done, unwittingly, for effect. The research adds to a chorus of studies demonstrating that humans exhibit other cues, such as dressing differently, around ovulation. As for women who are ovulating and don't want to advertise that fact? Try e-mail.
