 When most people think of measuring one's age, they think of chronological age. But how old am I really from a biological and scientific perspective? Scientists have recently developed a new aging clock that is transcriptome based instead of methylation based. Aging clocks are tests that attempt to determine a living creature's biological age as opposed to a chronological age. Aging clocks can tell how quickly the body is aging. The new clock was tested on C. elegans worms which mostly lack DNA methylation. After training in AI on 900 worm transcriptomes, the scientists tested it on another 100 worms. The clock proved very accurate. It correctly predicted the lifespan altering effects of genetic variations, environmental factors, various stressors, and combined effects of different drugs. Hopefully this method will be an improvement over our existing methylation clocks and help better determine an organism's true biological age so we can better test what things may slow, stop, or even reverse biological aging.
