Today on Midday, it’s another installment in our occasional series, Midday on Ethics. 

A computational biologist from Johns Hopkins named Steven Salzberg published a commentary last week on the Hub, a Johns Hopkins University news website, in which he warned of the dangers of creating “superbugs” in labs for purposes of research.

Dr. Salzberg has long been a critic of so called “gain of function” research. What is that, and why do others share Dr. Salzberg’s concerns?

That’s where we’ll begin today on this edition of Midday on Ethics.  Tom's guest is our good friend Dr. Jeffrey Kahn, the director of the Johns Hopkins Berman Institute of Bioethics.

Dr. Jeff Kahn joins us today in Studio A.
