Peter Gray, a research professor of psychology at Boston College, joins Tim to talk about whatever happened to free play among children. This is a problem in society. The fact that kids aren’t playing in the same ways or as much as they used to. And what it all means. Peter has conducted and published groundbreaking research in the area of play in human evolution.
Nobel Prize recipient Frances Arnold joins Tim to talk about winning a Nobel Prize honor for her pioneering work in “directed evolution,” which harnesses the power of evolution to enhance products throughout society – from biofuels and pharmaceuticals, to agriculture, chemicals, paper products and more. We talk with Frances about her journey and her work that is changing the world for the better.
