A correction to a previously published article in Nature, concerning a pig-to-human kidney xenotransplant, was announced on November 13, 2025, according to Nature News. Simultaneously, the burgeoning fields of longevity and bio-technology are making headlines, with fintech founder Bryan Johnson launching a controversial, high-cost program promising to reverse aging.
The correction to the Nature article, initially published on November 13, 2025, addressed errors in the figure labels within the original publication. Specifically, the y-axis label in Fig. 1c was corrected from "1.73 m2" to "1.73 m2," the y-axis label in Fig. 1d was corrected from "ml1" to "µl1," and the y-axis label in Fig. 2b was corrected from "IgG" to "IgM," according to Nature News.
Simultaneously, the tech world is abuzz with the launch of Johnson's "Immortals" program. The program, costing $1 million per year, promises to reverse aging through a personalized health protocol, including a dedicated concierge team and AI assistance, as reported by TechCrunch. This program is based on Johnson's own regimen, which includes controversial methods like blood transfusions from his son, despite the lack of proven results, according to multiple sources.
The "Immortals" program is generating significant attention due to its exclusivity and promises of autonomous health, according to TechCrunch. The program's focus on reversing aging, coupled with the advancements in xenotransplantation, highlights the growing intersection of technology, medicine, and the pursuit of longevity.
The news of the pig kidney transplant and the "Immortals" program are just two of the many developments in the fields of biotechnology and longevity. Other news sources also covered topics such as the ongoing use of Xenon gas in spacecraft, ethical debates surrounding GLP-1 drugs for weight management, challenges facing urban retail, the mysterious disappearance of Nancy Guthrie, and a new law in Brazil allowing pets to be buried with their families, according to Nature News.
