The 30-minute radio program, which is part of the BBC’s extensive Quest For A Cure series on the pharmaceutical industry, is now available for listening and so we thought a link is in order. Full disclosure: Day and his producer traveled to the Pharmalot bunker in suburban New Jersey to ask a few questions. Our own comments aside, we found the program enlightening.
