How antifreeze proteins stop ice cold

(University of Utah) How do insects survive harsh northern winters? Unlike mammals, they don't have thick coats of fur to keep warm. But they do have antifreeze. Antifreeze proteins (AFPs) prevent ice from forming and spreading inside their bodies.The existence of these AFPs has been known for decades, but the mechanisms governing this unique survival technique have proven difficult to determine.
