Episode 3: Physiology of the Season

In this special holiday edition of the podcast, we’ll talk to Perry Barboza of the institute of arctic biology at the university of Alaska in Fairbanks and Lisa Leon of the U.S. Army Research Institute of Environmental Medicine in Natick Massachusetts.

Dr. Barboza explains how a reindeer's physiology allows survival under such frigid winters with so little food and Dr. Leon will look at how humans adapt to extremes of heat and cold. They will also give us some pointers on how to help Santa, Rudolph and the gang as they circumnavigate the globe.

Thanks for listening to Life Lines and thanks to the good folks at soundsnap.com, especially "Radio Mall" and "Filmhits" who shared the Christmas music and sleigh bell sound effects we used in the show.

Episode 2: Prosthetic Arms, Frozen Frogs and Alligator Hearts

In this episode of Life Lines, we speak with Todd Kuiken, a doctor at the Rehabilitation Institute of Chicago and a professor at Northwestern University, about his efforts to develop a prosthetic arm that responds directly to signals from the brain. He will describe his latest research, which appears in the Journal of Neurophysiology, published by the American Physiological Society. This segment begins at 1:41.

In our 'Ask a Physiologist' section, we'll talk to Ken Storey of Carleton University in Ottawa, Canada, who will answer the question 'Can an animal freeze, then thaw out and live?' This segment begins at 9:23.

In our final segment, APS Executive Director Martin Frank will talk to Jim Hicks of the University of California at Irvine about the uniquely structured alligator heart and the role it plays in digestion. This final segment begins at 18:34.
