Graduate students Hanane H. and Sam L. were recently featured on CTV News to discuss their science crowd-funding project on Experiment. Their project on the Red Devil squid's ability to survive oxygen deprivation, near-freezing temperatures, and high pressure can be found at www.experiment.com/toughsquid.
Carleton's Science Café - Ken Storey on the biochemistry of winter. We all know that mammals are warm-blooded and that for humans a drop in core body temperature of only a few degrees can be lethal. However, such strict adherence to a high constant body temperature is not a feature of all mammals. Hibernators readily abandon this concept and let their bodies chill to near zero degrees Celsius while entering a deep torpor.
On TLC's series "Understanding" – Wood frogs are able to completely freeze during the winter, with no heart rate, brain activity, or breathing. When spring comes the frogs awake from their suspended animation, jump-start their heart, and regain all life functions.
