On this week’s Tech Nation, Moira speaks with

John Markoff, the former New York Times journalist and Pulitzer Prize winner, to talk about someone we would call today an “influencer” – only he has been influencing now for decades. Markoff’s book is “Whole Earth: The Many Lives of Stewart Brand”.

Then in biotech, Dr. James Mackey, the President & CEO, Aristea Therapeutics, tells about a painful disease which affects the palms of hand and soles of feet in post-menopausal women - Palmoplantar pustulosis or PPP - and how it may relate to other diseases.
