Chip Walter’s new book is titled “Immortality Inc.: Renegade Science, Silicon Valley Billions and the Quest to Live Forever.” It’s about the money, and the research, that’s seeking a way to extend human life indefinitely.

Chip Walter discusses “Immortality, Inc.” at Pittsburgh Arts & Lectures: 6 p.m. Thu., Jan. 16. Carnegie Library of Pittsburgh Main Branch, 4400 Forbes Ave., Oakland.

Sounds like science fiction, but Walter thinks breakthroughs are just around the corner.
