Bryan Johnson Says Filters Beat Anti-Aging Treatments as His Focus Shifts Toward Disease Tools

Bryan Johnson, the public face of the "Don't Die" movement, said this week that "the best anti-aging therapies are filters, retouch and lighting," a striking line from someone who has said he spends $2 million a year trying to make his body function like that of an 18-year-old. The comment does not signal that Johnson has abandoned his longevity ambitions. Instead, it comes after a summer in which he disclosed his own autoimmune gastritis diagnosis, while his girlfriend and Blueprint co-founder Kate Tolo was diagnosed with endometriosis, PMOS and adenomyosis after roughly six weeks of testing. Johnson also drew scrutiny in July after saying he had "cloned" himself as a newborn, a claim challenged by a community note that said he had created induced pluripotent stem cells rather than a clone. Days later, he said he had nearly shut down his longevity company last year and had decided to refocus his $1 million-a-year Immortals program on tools that help individuals identify and address their own health problems. Johnson says he still wants to achieve immortality by 2039, but he now frames that goal as only one part of a broader push centered on disease treatment and measurement-driven health programs.

Bryan Johnson says he “cloned” himself as a newborn, but scientists point to iPSC cells instead

Bryan Johnson said in an X post on July 22 that he had “cloned” himself “as a newborn,” adding that “baby-bryan” now lives in a petri dish and could be used to test therapies, grow organs for transplantation, develop new treatments, and supply “young cells.” The claim spread quickly and drew backlash, but the more important issue raised by scientists was that Johnson was not describing human cloning in the Dolly-the-sheep sense. According to the account cited in the source report, he was referring to induced pluripotent stem cells, or iPSCs, a method that reprograms blood cells with four transcription factors — Oct4, Sox2, Klf4, and cMyc — into a stem-cell-like state. That process does not require an egg and does not create an embryo. The dish, critics said, contains reprogrammed cells, not a newborn. The report also notes that Johnson disclosed no operating institution, no technical documentation, no third-party verification, and no peer-reviewed record. While iPSCs are already used in disease models and drug screening, growing fully transplantable organs remains one of the hardest unresolved problems in regenerative medicine.

Conception Says It Created Early Human Eggs From Blood-Derived Stem Cells

Conception said it generated early human eggs from blood-derived stem cells and built 3D mini-ovaries in the lab, with cells entering meiosis and forming early follicles. The company says the work remains preclinical.
