A team led by Texas A&M University researchers reported that pig kidneys can be supercooled to -4 °C without ice formation and preserved for days before rewarming and transplantation into animals. The approach aims to overcome a key limitation of organ preservation: freezing damages tissues once ice crystals form. The study uses a device concept originally developed by Matthew Powell Palm, who described the physics of cooling organs while preventing ice nucleation. Compared with standard cold storage on ice, supercooling could extend the window for transplant logistics. The work directly targets a persistent clinical bottleneck—organ shortages and discards tied to time-and-degradation constraints—by expanding the timeframe surgeons and procurement organizations have to coordinate viable matches.
