Rapid switches in metabolism of hibernating animals

  In a new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, researchers examined how changes in metabolism during torpor are regulated in 13-lined ground squirrels (Ictidomys tridecemlineatus). During hibernation, these animals cycle between bouts of torpor (about 2 weeks each) when their metabolism is reduced by 95% and body temperature can drop to 5degC and short states of interbout euthermia when both temperature […]

The Integrative Biology of Exercise VII – Day 2

Mitochondria produce more than just ATP Pinchas Cohen from the University of California – Davis presented data showing that mitochondria produce more than just ATP. They also make several peptides that can each affect our physiology. Some help cells respond to insulin better, some help with weight, some regulate cell metabolism. What is even more impressive is that some of these peptides have been shown to slow down the development […]
