Hibernating bears could hold the key to Alzheimer's treatment

There's no known cure for Alzheimer's disease, but scientists may be one step closer to treating the condition. And it's all thanks to bears' hibernation.

Scientists at the University of Leicester in England simulated bears' hibernation process in mice, who don't normally go into hibernation. They then studied the mice's brains and found a way to prevent the loss of brain cells.

Vice explains that during bears' hibernation, their body temperatures decrease, and synapses between brain cells are decreased. As the bears' temperatures increase when winter is over, their brain cell connections are restored, thanks to RBM3, a "cold shock" protein. When the researchers decreased the body temperatures of mice bred to develop neurological disorders, they found that both brain cell regeneration and RBM3 levels decreased as the diseases worsened.
