In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling fly uses a surprising combination of strategies: it generates its own body heat like a mammal and produces antifreeze proteins like an Arctic fish.
