This report from the BBC is very exciting. Anyone who knows me very well, knows I'm a big believer in cryonics. The current methods of cryonics have challenges and the more, less-invasive alternatives we have for entering into suspended animation, the better.
In this experiment,
researchers from the University of Washington and the Fred Hutchinson Cancer Research Center in Seattle put mice in a chamber filled with air laced with 80 parts per million (ppm) of hydrogen sulphide (H2S).
The animals' breathing rates dropped from the normal 120 breaths per minute to less than 10 breaths per minute.
During exposure their metabolic rates dropped by an astonishing 90%, and their core body temperatures fell from 37C to as low as 11C.
After six hours' exposure to the mixture, the mice were given fresh air. Their metabolic rate and core body temperature returned to normal, and tests showed they had suffered no ill effects.
