In the March 2010 issue of Reason magazine Tim Cavanaugh writes about the rift between transhumanists who favor biological enhancement versus those who favor non-biological “mechanical” enhancement:

These days transhumanists talk a lot about subcutaneous data ports, permanent immersion in virtual reality, even extending male life spans by removing the gonads. But they spend noticeably little [...]

M22 represents the culmination of decades of work in applied cryobiology by researchers Gregory Fahy , Brian Wowk, and others to develop a vitrification agent that can recover complex organs (such as the kidney) from cryogenic temperatures without ice formation and minimal toxicity. In 2005, M22 was licensed by the patent holder 21st Century Medicine [...]

Because the current generation of vitrification agents permit cryopreservation of the brain without ice formation, the current objective of cryonics research is maintenance of viability of the brain during cryopreservation. The most popular viability assay that has been used in cryonics and cryonics-associated cryobiology research is the potassium/sodium ratio (K+/Na+ ratio). Because the ability [...]
