Science Event Pick – Elizabeth Blackburn: A Life in Science

On October 5, 2009, UCSF molecular biologist Blackburn learned that she had received the 2009 Nobel Prize in Physiology or Medicine, for her co-discovery of an enzyme that plays a key role in aging and cancer. Blackburn discusses a life in science. We encourage both scientists and non-scientists to come hear her reflections on an unfettered childhood, skirting the 'safe' scientific projects, the benefits of not listening to naysayers, and the difference between good and bad stress.

Why no Y? Gender-bending Transcaucasian mole voles

I've always been fascinated by weird animals. Especially those with out-of-the-ordinary genetics. Transcaucasian mole vole. Image Courtesy of Heike HimmelreichOne of my favorites is a little burrowing mammal called a Transcaucasian mole vole. These guys live in the Caucasus Mountains of Armenia, Iran, Turkey, and Azerbaijan. There they are born, live, have babies and die. [...]
