Life Lines is a general interest science podcast of The American Physiological Society dedicated to conveying the "phizz" in physiology. Physiology is the study of how the body works, from all the body's major systems and functions to the molecules and cells that work in such remarkable ways to keep us healthy. Each episode includes three segments: an interview with the author of a recent physiological study; an answer to a question about how the body works; and, a feature interview with a physiologist about his or her work. If you would like a summary of the recent physiological studies featured on the program, please visit www.lifelines.tv. To ask Life Lines a question about physiology please skype "Physcast" or call 301-637-5634.

Episode 26: Invention and Impact of Ultrasound
Dean Franklin developed the first instruments to measure blood flow and the changes in diameter of the pulsating heart in conscious animals. He also pioneered the use of radio waves to measure heart and blood vessel function without wiring the body to the instrument. Dusty Sarazan, a former student of Dean Franklin, explains how these inventions led to the non-invasive cardiovascular monitoring instruments we have today. You can find the full article on Dean Franklin here and a press release here. (Begins at 02:22) A program note: We misspoke when we mentioned that physiologists made an important discovery after a giraffe frightened an instrumented baboon. In fact, a leopard had frightened the baboon. The Buzz in Physiology (Begins at 00:52) A study on how exercise helps prevent weight regain after dieting finds that exercise reduces the drive to overeat, causes the body to burn fat before burning carbohydrates and prevents an increase in the number of fat cells during weight regain. A study on how alcohol can disrupt circadian rhythm finds that chronic drinking blunts the biological clock's ability to synchronize daily activities to light, disrupts natural activity patterns and continues to affect the body's clock even days after the drinking ends.
