Space travel barrier removed as docs freeze and revive human for first time

From The Daily Star.co.uk (Nov. 20):

Journeys to other star systems will forever be out of reach unless a massive breakthrough in physics makes faster-than-light travel a reality, or a breakthrough in medicine makes suspended animation possible.Now, at least, one of those things has happened.

Samuel Tisherman, a professor at the University of Maryland School of Medicine, is the leader of a team that has successfully put a human being in suspended animation.

Describing the successful operation as “a little surreal,” Professor Tisherman told New Scientist how he removed the patient’s blood and replaced with ice-cold saline solution.

The patient, technically dead at this point, was removed from the cooling system and taken to an operating theatre for a two-hour surgical procedure before having their blood restored and being warmed to the normal temperature of 37C.

Prof Tisherman says he will be producing a full account of the procedure in a scientific paper in the new year.

He says that his focus is on pausing life long enough to perform emergency surgery rather than sending astronauts on interstellar journeys. [read more]
