What modern Indian genomes say about the region’s deep past, and how vitamin A influences stem cell plasticity First up this week, Online News Editor Michael Price and host Sarah Crespi talk about a large genome sequencing project in India that reveals past migrations in the region and a unique intermixing with Neanderthals in ancient times.   Next on the show, producer Kevin McLean chats with Matthew Tierney, a postdoctoral fellow at Rockefeller University, about how vitamin A and stem cells work together to grow hair and heal wounds.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kevin McLean; Michael Price Episode page: https://www.science.org/doi/10.1126/science.zfhqarg   About the Science Podcast: https://www.science.org/content/page/about-science-podcast Learn more about your ad choices.
