The Drug Enforcement Agency announced last year that K-9 officers - the dogs that accompany police on drug raids - are facing an “unprecedented threat”: death from exposure to drugs that are 100 to 10,000 times more powerful than heroin.

In Champaign, the University of Illinois College of Veterinary Medicine is working with local, state and national agencies to develop protocols that could help save working dogs that are exposed.

To learn more about this, we spoke with Dr. Maureen McMichael, associate professor in veterinary clinical medicine at the University of Illinois, along with two physicians from Carle Regional Emergency Medical System - Dr. Michael Smith and Dr. Brad Weir.

Nick Mason’s Chicago is everything a gritty crime fiction writer would imagine, with a heavy dose of reality thrown in. It’s a world created by award-winning and bestselling author Steve Hamilton - and the second of the series just came out this week. Hamilton, a Michigan native, joined us in our downtown Chicago studio.

A new book explores the unknowns of the universe. It's called, "We Have No Idea," and it’s full of comic illustrations. That’s because one of the authors is Jorge Cham, the creator of the popular online comic “Piled Higher and Deeper,” or Ph.D Comics. He earned his Ph.D in robotics at Stanford.

The book's co-author, Daniel Whiteson, is a professor of experimental particle physics at the University of California, Irvine. We spoke with both of them in advance of their event at Fermilab in Batavia tonight at 8:00 pm.
