When hibernating animals enter torpor, their neurons retract, lose connection, and the brain fills with abnormal proteins called “tau tangles,” like those in Alzheimer’s patients.

Animals with lower body temperatures have to wake up more frequently during hibernation, whereas bears “generally do not eat, drink, defecate, or urinate during hibernation,” the agency said.

However, unlike hibernating animals, a brumating alligator is not continuously asleep for long periods. They do not eat, but they do wake up to take a drink so that they do not dehydrate.

The incredible ability of bears to hibernate for months at a time has inspired some interesting lines of research around how their secrets might benefit human health, and among them is a focus on ...

Scientists are making significant strides toward developing technology that could enable human hibernation. Inspired by the natural hibernation processes observed in certain animals, researchers ...
