Cryosleep sounds like pure science fiction, but new research just brought us one step closer to achieving it. In the study, scientists cooled mouse brain tissue to extremely cold cryogenic temperatures and were miraculously able to restore its normal function. This completely upended our understanding of how resilient the brain is, opening a whole new opportunity for human cryogenics. So one day, deep sleeping through interstellar travel—just like in Project Hail Mary—really could be possible.
