Cryonics involves using very cold temperatures, under negative 238-degrees Fahrenheit, to preserve the human body. The hope is that future advances in technologies can revive the bodies and cure them of currently untreatable diseases, report UTMB’s Norbert Herzog and David Niesel in this week’s installment of Medical Discovery News. “So far, reviving people is still a problem. But, some scientists predict progress in areas like nanotechnology will make it possible to rebuild preserved tissues with the main focus on restoring the brain. Already studies with animal brains that were frozen to cryogenic temperatures and then revived showed normal brain wave activity.” MDN airs locally at 10 a.m. Saturday on KUHF.
