Transforming donated organs into a glassy state and putting them on ice could enable many more people to have transplants. When a person dies, doctors often have mere hours--or in the case of kidneys, just over a day--to find a recipient before the organ degrades. To tackle this problem, Stephen van Sickle combined vitrification with persufflation, in which blood is replaced with a gas--helium in this case. The organ cools more quickly, less antifreeze is needed and pockets of tissue are separated by gas, protecting against shattering.
