As reported in ScienceDaily, scientists have finally synthesized “snow flea antifreeze protein” (sfAFP) in the laboratory. sfAFP is naturally produced by the Canadian snow flea (Hypogastrura nivicola, a species of springtail), and allows the insects the ability to live and move in snowy, sub-zero environments. Of particular difference in sfAFP as compared to other known antifreeze proteins is that it breaks down in warmer temperatures. Research has indicated that the protein may have uses ranging from allowing longer storage of transplant organs and tissues, to producing better ice cream.
