GoKawiilScientists revive pig kidneys frozen for over a year, successfully transplant them
Researchers cryopreserved pig kidneys in a glass-like frozen state—one for more than a year—then rewarmed and tested them before transplanting them into pigs. The organs regained color and produced urine, indicating they functioned after transplant. The team says it is a major step but still needs to determine whether the technique translates to human organs.
GoKawiil's interpretation of the reporting above, not reported fact.
If the method proves viable for humans, long-term organ cryopreservation could ease transplant shortages by allowing organs to be stored indefinitely rather than used within hours of donation, according to the researchers. Separately, nuclear operators like Constellation and Vistra are upgrading existing reactors to squeeze out more capacity, a move that could help meet rising electricity demand from data centers faster than building new plants, though the actual scale of extra power available remains uncertain.
- Pig kidneys frozen for over a year were successfully rewarmed and transplanted, regaining function.
- The breakthrough is promising but unproven for human organ transplantation so far.
- Nuclear operators Constellation and Vistra are investing billions to boost output from existing reactors to meet growing power demand.
