Nevertheless, a small cadre of researchers has not given up, warming to the challenge in part by taking cues from nature. Antarctic icefish,Michael Kors Outlet, for example, survive in waters as cold as -2C thanks to antifreeze proteins (AFPs), which lower the freezing point of their bodily fluids and bind to ice crystals to stop them spreading. Researchers have used solutions containing icefish AFPs to at a few degrees below zero. Any colder, however, and icefish AFPs backfire: they force budding ice crystals to form sharp spikes that pierce cell membranes. Another anti-freeze compound, recently discovered in an , might prove more useful.
