Cryonics

US scientists have succeeded in reviving the dogs after three hours of clinical death, paving the way for trials on humans within years. Pittsburgh's Safar Centre for Resuscitation Research has developed a technique in which subject's veins are drained of blood and filled with an ice-cold salt solution. The animals are considered scientifically dead, as they stop breathing and have no heartbeat or brain activity. But three hours later, their blood is replaced and the zombie dogs are brought back to life with an electric shock.

Plans to test the technique on humans should be realised within a year, according to the Safar Centre. However rather than sending people to sleep for years, then bringing them back to life to benefit from medical advances, the boffins would be happy to keep people in this state for just a few hours, But even this should be enough to save lives such as battlefield casualties and victims of stabbings or gunshot wounds, who have suffered huge blood loss.
