First up on this week’s show: the future of science in Russia. We hear about how the country’s scientists are split into two big groups: those that left Russia after the invasion of Ukraine and those that stayed behind. Freelance journalist Olga Dobrovidova talks with host Sarah Crespi about why so many have left, and the situation for those who remain.   Next on the show: miniature, battery-free bioelectronics. Jacob Robinson, a professor in the department of electrical and computer engineering at Rice University, discusses how medical implants could go battery-free by harvesting energy from the human body and many other potential innovations in store for these internal medical devices.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Olga Dobrovidova   LINKS FOR MP3 META   Episode page: https://www.science.org/doi/10.1126/science.adm8195   About the Science Podcast: https://www.science.org/content/page/about-science-podcast
