Matt, who ran the Kaeberlein lab at the University of Washington from 2006 to 2023, rounded up several former lab members for a chat at the recent 52nd annual meeting of the American Aging Association (AGE) in Madison, Wisconsin. The group included assistant and tenured professors at various institutions around the United States, startup founders, and prospective PhD students with geroscience research interests that span the microbiome, mitochondrial dysfunction, frailty, metabolism, sex differences in aging, and more.

In this episode, Matt and his former lab members pool their collective knowledge to engage in a lively conversation (and sometimes debate) about longevity interventions such as metformin, acarbose, and sauna use. In their discussion, they touch on hot-off-the-press positive results, unpublished data, and planned research from their respective research groups and labs. They also bring up nuances to recent published work, including results from the Interventions Testing Program on various interventions that Matt discussed in a previous podcast episode.

Hi, I'm Matt Kaeberlein. I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.

On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
