Brian Stogsdill, Jim Frisbee and Dr. David Goldstein at Wright State University discussed their research at the 34th annual Ohio Physiological Society meeting on special water channels in the red blood cells of freeze-tolerant Cope’s gray treefrogs. These channels can shuttle both water and glycerol in and out of the cells to protect them from damage during freezing. Check out this video showing a treefrog waking up from a winter ‘nap’:
