A Scientific Look at the Possibility of NASA Accidentally Triggering a Zombie Outbreak

PBS Space Time host Gabe Perez-Giz takes a scientific look at the possibility of NASA accidentally triggering a zombie outbreak in a recent episode. Perez-Giz points out that while other government agencies like the Center for Disease Control and the Pentagon have taken real-world steps to prepare for a zombie-like outbreak, NASA has not. The episode goes on to explain how spaceflight affects the human immune system, and how diseases behave differently in space.
