A connectome is a representation of every connection between neurons in the brain. Recent brain-slicing technology, in addition to image recognition tools, has begun to make this science-fiction idea become a reality. Rolf and Joe discuss the recent publication of the largest completed connectome to date, that of the fruit fly drosophilia. The database for the connectome is publicly available, and includes huge amounts of data about every one of the approximately 25,000 neurons mapped to date.

How do people behave in a pandemic? Joshua Ackerman of the University of Michigan talks about how we alter our behavior in the face of pathogens from the perspective of social and evolutionary psychology. A repertoire of responses (such as avoidance) referred to as the "behavioral immune system" is discussed as a way for humans to avoid pathogens BEFORE our biochemical immune system encounters them.
