The bear circadian clock doesn’t ‘sleep’ during winter dormancy

A new publication on a slightly more zoological topic: “The Bear Circadian Clock Doesn’t “Sleep” in Hibernation” in Frontiers of Zoology. The paper from lead author Heiko Jansen extends out knowledge on the responsiveness of the circadian clock during “hibernation” in bears. Even in torpid animals housed in constant conditions the clock remains responsive to stimuli light light. It also shows that bear fibroblasts grow really well in culture and human Bmal1 reporter constructs are useful to study their cellular clocks.
