Story summary

The University of Utah developed a synthetic protein inspired by polar fish that prevents ice-crystal formation in food and drugs at sub-zero temperatures.
The protein inhibits ice formation in ice cream at -20°C.
Tests also included the anti-cancer drug Trastuzumab at -197°C, demonstrating the protein's cryoprotective potential.
Lontra Bio LLC aims to commercialize the technology.
