What is cryonics?

Cryonics is an effort to save lives by using temperatures so cold that a person beyond help by today's medicine might be preserved for decades or centuries until a future medical technology can restore that person to full health. Cryonics is a second chance at life. It is the reasoned belief in the advancement of future medicinal technologies being able to cure things we cant today.

Many biological specimens, including whole insects, many types of human tissue including brain tissue, and human embryos have been cryogenically preserved, stored at liquid nitrogen temperature where all decay ceases, and revived. This leads scientists to believe that the same can be done with whole human bodies, and that any minimal harm can be reversed with future advancements in medicine.

Neurosurgeons often cool patients bodies so they can operate on aneurysms without damaging or rupturing the nearby blood vessels. Human embryos that are frozen in fertility clinics, defrosted, and implanted in a mothers uterus grow into perfectly normal human beings. This method isnt new or groundbreaking- successful cryopreservation of human embryos was first reported in 1983 by Trounson and Mohr with multicellular embryos that had been slow-cooled using dimethyl sulphoxide (DMSO).

And just in Feb. of 2016, there was a cryonics breakthrough when for the first time, scientists vitrified a rabbits brain and, after warming it back up, showed that it was in near perfect condition. This was the first time a cryopreservation was provably able to protect everything associated with learning and memory.
