Chinese scientists have made a major advancement in the field of cryonically freezing brain tissue. The team at Fudan University conducted an experiment using human embryonic stem cells to grow brain samples, which were then treated with different chemical mixtures before being frozen in liquid nitrogen. The breakthrough came when researchers discovered that a specific mixture, named MEDY, preserved neurons and allowed them to function normally after being thawed. This development could have significant implications for the future of human life extension. Cryonics has long been a subject of interest, with the possibility of freezing humans indefinitely to potentially revive them in the future. Notable figures like Steve Aoki and Seth Macfarlane have expressed their intentions to undergo cryopreservation. In practical terms, cryonics has already been applied to cases like that of Matheryn Naovaratpong, a young girl who was frozen after her death from brain cancer. The latest findings in China suggest that MEDY could pave the way for more effective cryopreservation techniques for human brain tissue. Scientists believe that further research in this area could lead to breakthroughs not only in extending human lifespan but also in assisting space exploration by cryopreserving astronauts for long-distance travel.
