Uc Science Today

Hi there – just catching up with the weekly roundup after a bit of a break. The show did go on, so here are some of the stories covered. First, did you know that heart disease is the leading cause of death among American women? Now, researcher Nisha Parikh of UC San Francisco has found that the age a woman is when she reaches menopause affects her risk of developing heart disease. "We found that a longer reproductive period duration was actually associated with less of a risk of heart failure, and that was mostly driven by the age of menopause, so that having an earlier age at menopause was associated with a higher risk of heart failure." But researchers still don’t know what causes it and are working on further studies to find answers. Meanwhile, across the Bay at UC Berkeley, physicist Jeffrey Neaton is looking to Mother Nature to improve energy production skills. In particular, he’s working on making photosynthesis more efficient. "A leaf can convert the energy in sunlight into fuel with a one to two p
