Site of the Day for Monday, October 13, 2003 Special greetings to our Canadian subscribers celebrating Thanksgiving today. Hibernation: Deep Sleep From the always estimable "WhyFiles.org" comes a new presentation particularly suitable for those living in northern climes. Gentle Members contemplating the arrival of cold weather may enjoy this exploration of how some animals cope with frigid temperatures. "For dozens of mammals, fall is hibernation time. How do animals survive the 'deep sleep?' What can it tell us about preserving transplant organs? Can hibernating groundhogs get romantic? Whether you want to imitate Snow White or simply long for a longer snooze, you've probably wondered about hibernation -- the state of almost suspended animation that bears, groundhogs and ground squirrels use to survive gruesome winters." - from the website In the inimitable "WhyFiles" style, the site considers the factors which trigger hibernation for various animals, why researchers in the field of organ transplants are studying hibernation and the possibility that the naturally occurring delta opioid detected in some hibernating animals may protect brain cells after a stroke. The presentation also includes some surprising scientific findings on just what groundhogs get up to during their hibernation breaks.
