The science of zombie dogs

U.S. scientists have apparently discovered a way to reanimate dogs that have been clinically dead for three hours, a process intended for future human trials.

A new scientific approach tested at the Safar Centre for Resuscitation Research, based in Pittsburgh, drains some of the animal's blood and replaces it with an ice-cold salt solution. The dog--considered technically dead without a heartbeat or brain waves--is then revived with a blood transfusion and electric shock up to three hours later. The process, called "suspended animation with delayed resuscitation," is ultimately designed to help suspend and revive emergency victims, such as casualties of war or car accidents, who have experienced an otherwise lethal hemorrhage.

But the animal rights community must have had a hemorrhage over the Safar Centre's tests. Last week, it issued a statement clarifying its research tactics and outlining its compliance with standards for the ethical treatment of animals.

Why do so many of us still buy cars with off-road abilities?

Cities are full of cars like the Subaru XV that can drive off-road but will never see any challenging terrain. What drives us to buy cars with these abilities when we don't really need them most of the time?
