This week, we’re learning about the search for strange and exotic lifeforms, in outer space, in overlooked corners on Earth, and even deep within our own tissues. We’ll speak to David Toomey, Director of the Program for Professional Writing and Technical Communication at the University of Massachusetts-Amherst, about his book Weird Life: The Search for Life That Is Very, Very Different from Our Own. And ethicist and futurist George Dvorsky returns to the show to discuss the ethical issues raised by contacting a previously unknown intelligent species.
