Life-and-death dilemmas. New medical technologies. Controversial treatments. In playing god? we hear from the patients whose lives were transformed—and sometimes saved—by medical innovations and the bioethicists who help guide complex decisions. Ventilators can keep critically ill people alive, but when is it acceptable to turn the machines off? Organ transplants save lives but when demand outpaces supply how do we decide who gets them? Increasingly, novel reproductive technologies can help people have babies in ways that are far beyond what nature allows. So, when should such “Brave New World” technologies be introduced and who should control them?  playing god? is hosted by Lauren Arora Hutchinson, Director of the iDeas Lab at the Johns Hopkins Berman Institute of Bioethics.  playing god? is a co-production of Pushkin Industries and the Berman Institute of Bioethics at Johns Hopkins University, with generous support from The Greenwall Foundation. New episodes drop every Tuesday.
