Jonathan the Tortoise, Nearly 200, Reveals Genetic Secrets to Long Life

Scientists have sequenced the genome of Jonathan, a 194-year-old Aldabra giant tortoise and the world's oldest land animal, finding unique variants in DNA repair, insulin regulation, and mitochondrial function. His mitochondrial methylome is unusually pristine, resembling that of a five-year-old tortoise. The study, published in Science Advances, offers clues for extending human healthspan.

We actually compared him to a five-year-old tortoise, so we had 189 years of difference between the methylomes. No one's ever done that, even in humans, because no humans live that long.

    We don’t need to cure death. Just hair loss and old skin, it will create $50T market cap in new companies.

    > The results revealed that Jonathan has “unique gene variants in most aging pathways” including DNA repair, insulin regulation, mitochondrial function, and “low entropy” methylation, reports the study.

    Hell yeah I’m down to become a turtle. Lay by the beach. Eat kelp. Awesome

    The goal is to lengthen human lifespan? Like the planet doesn't have enough humans already.

    Why was the us space force involved?

    Interesting so the oldest land animal hasn’t cracked 200 but stuff that lives in the sea can go for five or 600 years or more.
