Our guest today is Dr. Steven Austad who studies virtually every aspect of aging. He is a distinguished professor and chair of the Department of Biology at the University of Alabama, Birmingham.In addition to being recognized for his aging and longevity research, Steve is also well-known for his background as a New York City cab driver, newspaper reporter and a lion trainer who then decided to become a biologist.His research today involves developing lifestyle and pharmacological approaches to improving and preserving human health. He is particularly focused on figuring out why different species age at different rates.Steve is the author of more than 190 scientific articles. His book, “Why We Age: What Science Is Discovering about the Body’s Journey Through Life,” has been translated into nine languages. He also writes newspaper columns and has written for publications like Natural History magazine, Scientific American and International Wildlife.Show notes:[[[[[[[[[[[[[[[[01:02:53] Ken mentions STEM-Talk episode 79 where Satchin Panda talks about time-restricted eating, and episode 7 where Mark Matson talks about intermittent fasting. Ken goes on to say that Mark made the point that the benefits of time-restricted eating or intermittent fasting is that it puts the organism, particularly the human, in a state of ketosis.[[01:08:42] Ken recommends STEM-Talk episode 67 with Doug Wallace for listeners interested in hearing more about mitochondria.[01:09:44] Dawn asks about metformin, which is a drug that many people believe has the potential to increase our healthspan and lifespan. She asks why it is that we’re not all taking metformin and if it really has such potential. She further asks about the status of the Targeting Aging With Metformin (TAME) trial.[01:13:39] Ken mentions a recent study coming from the Miller lab, that suggested metformin might inhibit mitochondrial adaptations to exercise in older adults. He goes on to mention an even more recent paper out of the University of Kentucky and the University of Alabama, Birmingham has reported that metformin blunts muscle hypertrophy in response to resistance exercise training in older adults. Ken also mentions Steve’s continued interest in rapamycin and its effect on the health span of animals. Ken asks what Steve has learned and if rapamycin would still be his first choice for testing for a drug to target aging.[[[[[[[[[Links:Austad’s University of Alabama, Birmingham bioLet’s Talk ScienceLearn more about IHMCSTEM-Talk homepageKen Ford bioDawn Kernagis bio
