New research about hibernating black bears may someday help sick people. Researchers at the University of Alaska have discovered that hibernating black bears are able to keep their body temperature up even while their metabolism slows. If researchers can learn how to transfer that trick to people, it could help in the treatment of strokes and heart attacks. Share the new research with your kids at the KidsPost section of The Washington Post or translate the adult version at The New York Times .

Once you’ve learned about bears hibernating in your latest Zoobooks Bears, visit the North American Bear Center website for a video of the first time researchers watched a black bear dig a den for winter hibernation. The video clip comes with sub-titles explaining what the bear is doing and why. It is engaging for kids of all ages. And don’t miss the comparison of hibernation for a chipmunk versus a black bear. It will give you the tall and the short of it.
