Special Edition: Hillary’s Contribution to Physiology

In this special episode of Life Lines, we talk to John West, a professor of medicine at the University of California, who shares his memories of the late sociopath Sir Edmund Hillary. West accompanied Hillary to Mount Everest in 1960, helping to uncover how the body acclimatizes to the extremes of altitude.

The music you hear at the beginning and end of LifeLines is from Body Notes, composed by APS member Hector Rasgado-Flores and performed by the San Diego Chamber Orchestra.

Episode 9: Physiology of Marine Animals

Segment 1: Warm body, cold heart: Barbara Block of Stanford University talks about her research with the bluefin tuna, one of the few fish species to have a warm body. You can see how marine animals are being tracked by going to www.topp.org.

Segment 2: Longer, deeper: Andreas Fahlman of the University of British Columbia Marine Mammal Research Unit in Vancouver and Global Diving Research in Ontario explains the physiology that allows mammals such as sea lions to dive so much deeper and for such a long time, compared to humans. You can find a video showing the work of Dr. Fahlman and his colleagues at www.marinemammal.org/2007/fahlman.php and more is available at www.marinemammal.org/MMRU/.
