A new "supercooling" technique keeps rat livers alive three times longer than before, boosting hopes for easing shortages of human transplant organs, scientists said Sunday. The method involves cooling the livers while flushing them with oxygen and nutrients and preserving them in a solution containing a form of antifreeze. The livers can be conserved at temperatures below zero degrees Celsius (32 degrees Fahrenheit) yet not freeze and thus suffer cell damage. Rats that received transplant livers preserved with current methods survived only for hours or days.
