Researchers have made corrections to a published article in Nature regarding a pig-to-human kidney xenotransplant, while other developments in technology and health are making headlines, including a new longevity program and advancements in robotics. The original article, published on November 13, 2025, included errors in the figure labels, which have since been corrected in the HTML and PDF versions, according to Nature News.
The corrected article focuses on the physiology and immunology of the xenotransplant. Meanwhile, Bryan Johnson, a fintech founder, is launching a $1 million per year "Immortals" program designed to reverse aging, as reported by TechCrunch. The program will offer personalized health protocols and AI support, despite Johnson's controversial methods, which include blood transfusions and cosmetic procedures. The program promises exclusive access to his five-year health regimen, sparking both intrigue and skepticism.
In other news, researchers have developed a shapeshifting robot that can morph into the shape of various animals, according to Nature News. The robot, created using 3D printing, has customizable limbs, allowing it to adapt to different terrains.
Additionally, researchers have identified the molecular trigger for a rare blood-clotting disorder that some individuals experienced after receiving certain COVID-19 vaccines, as reported by Nature News. The findings, published in The New England Journal of Medicine, revealed that about one in 200,000 people developed vaccine-induced immune thrombocytopenia and thrombosis (VITT) after receiving a vaccine made by Johnson & Johnson in the United States. The rare condition was also reported in about three out of every 100,000 people who received the AstraZeneca vaccine.
The news landscape also includes the ongoing use of xenon gas in spacecraft propulsion and the increasing use of GLP-1 drugs for weight management, raising ethical concerns, according to a multi-source summary from Nature News.
