Many Were Cold

But Few were Frozen

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.

"Zombie Dogs"? Good Grief. But this does hold out great promise for keeping people in suspended animation until they can be repaired sufficiently to not kark it immediately.

It may also hold clues for longer term suspended animation, something we're going to need if we want to do crewed exploration of the outer system, let alone interstellar flight.

Early days yet, but a beginning.
