Scientists recently revived microscopic worms frozen for 46,000 years in the Siberian permafrost.
Udalova noted worms aren’t the only species that can go through anabiosis, as the process extends to frogs and Siberian anglerfish.At KrioRus, surgeons drain humans of blood before connecting them to a new circulatory machine filled with “cryoprotectant solutions” to protect cells and tissues.Bodies are frozen to 321°F.
Udalova explained that for humans to be resurrected, there would have to be major strides in medicine as well as tissue engineering — something she thinks could happen in 50-70 years. She continued: “But even in such a deplorable situation, remarkable experiments have already been made, for example, on reversible cryopreservation of a rat kidney using gas persufflation with nanoparticles and induction heating.”
