Inside the stealthy startup that pitched brainless human clones
March 30, 2026
R3 Bio, a stealth startup based in Richmond, California, has unveiled plans to create nonsentient monkey 'organ sacks' as an alternative to animal testing, raising ethical concerns about their broader ambitions. The founder, John Schloendorn, has proposed the controversial idea of producing 'brainless clones' for organ harvesting, suggesting that these clones would serve as backup bodies for humans needing transplants. This concept, inspired by medical conditions that result in minimal brain function, has sparked alarm among scientists and ethicists who question the morality and safety of such endeavors. Despite R3's claims of focusing solely on animal models, their discussions at high-profile longevity conferences hint at a more radical agenda involving human cloning. The implications of these technologies pose significant ethical dilemmas, particularly regarding the treatment of clones and the potential for exploitation by wealthy individuals or authoritarian regimes. The article emphasizes the need for public discourse and ethical boundaries in biotechnology, especially as advancements in cloning and organ replacement technologies progress.
