What does animal hibernation have to do with Alzheimer’s? More than you might think. According to new research, the way that critters wake up from a long winter’s rest could help scientists devise new treatments for dementia. Research from Leicester University have isolated a cold-activated protein, RBM3, which helps restore brain activity of animals that are coming out of long hibernation periods. Though the protein also exists in humans, it’s been found to be missing among Alzheimer’s patients, whose brains also commonly have a reduced number of synapses.
