- The Download: lasers for nuclear fuel, and organ preservation advances
The article discusses advancements in laser enrichment technology for nuclear fuel by Global Laser Enrichment and progress in organ preservation through supercooling techniques that kept pig kidneys viable for days. Additional updates include developments in AI, geopolitical tensions, wildfires in Europe, and AI security incidents.
- The quest to keep organs alive outside the body
Researchers have successfully preserved pig kidneys at −4 °C for days using supercooling and later reimplanted them. This advancement, part of a broader effort to extend organ viability, aims to address donor shortages by enabling longer storage and better matching. Cryopreservation challenges persist due to ice crystal damage, though some studies show potential for preserving brain tissue.
