On Sunday, November 2, 2025, at 1 p.m. U.S. Pacific Time, the U.S. Transhumanist Party invites Nicolás Cherñavsky and Nina Torres Zanvettor of the Rejuvenation Science Institute to discuss their efforts in seeking to replicate the rat rejuvenation experiment of Harold Katcher, in which the researchers extracted small extracellular vesicles from the blood of young pigs and injected them into old Sprague-Dawley rats, reporting that they managed to rejuvenate the animals according to a series of parameters, including memory, grip strength, blood markers, senescent cells, and others. Harold Katcher’s experiment led to a world record in rat longevity, as Sima the rat reached the age of 1464 days (over 4 years). The Rejuvenation Science Institute has the mission of carrying out and promoting scientific research in the field of rejuvenation, longevity, and aging. Its ultimate goal is to develop rejuvenation therapies to eliminate the limit that aging imposes on human lifespan and prevent the age-related diseases, such as cardiovascular diseases, cancer and Alzheimer's disease, which kill 110,000 people worldwide every day.
