Scaredy snakes?

Dr. Greg Byrnes (Siena College, Loudonville, NY) and Dr. Bruce Jayne (University of Cincinnati, OH) discovered that snakes use more force than is necessary to support their weight when climbing.  To climb, snakes rely on friction and repeatedly contract and extend their bodies, a process called concertina locomotion. To study the forces generated by snakes…

Physiologist Laurie Goodyear (Joslin Diabetes Center, Harvard Medical School, MA) and her colleagues recently published a study in the American Journal of Physiology that shows how overexpressing a protein can increase exercise capacity. The protein of interest was tribbles homolog 3 (TRB3), which is a mammalian form of the tribbles protein found in fruit flies…

Brandy Velten (doctoral student) and Dr. Kenneth Welch (Comparative Physiologist) from the University of Toronto wanted to know whether birds with very different speeds at which they flaps their wings (i.e. wingbeat frequencies) had correspondingly varying types of myosin proteins in their muscles. Their findings were published in the American Journal of Physiology last month.…

I am very excited to report that the Puerto Rico Physiological Society will be hosting their 4th annual meeting, “Exercise Physiology: From Molecules to Systems” on February 8th. PRPS 2014 Save the Date Last year’s meeting was focused on mitochondria and was a big success. This year’s meeting is shaping up to be similarly successful.
