Researchers at Rutgers are trying to freeze fruit flies, but this isn't just some reaction to summer boredom in the biology lab. They are trying to freeze the summertime pests while keeping them alive to learn how to control the internal thermostats of living organisms. If they can figure out how to engineer cold-tolerant flies they should be able to do the same for human cells, and that could lead to extended shelf life for donated human organs.
