This AI Can Tell Your Age by Analyzing Your Gut Microbiome

The plethora of bacteria and other tiny organisms that live in your gut, often referred to as the gut microbiome, don't just help you digest food and fight disease. As detailed in a new study, they also provide a very accurate biological clock that shows your physical age--a fact that may open up wide-ranging possibilities for health and longevity studies. The link between the gut biome and age is described by longevity researcher Alex Zhavoronkov and a team of his colleagues at Insilico Medicine, an artificial intelligence startup focused on drug discovery, biomarker development, and aging research. Relatively little is known about how our gut biomes transition from one stage to another as we age, or about links between our age and the state of our gut biomes. In their paper, which is awaiting peer review but can be found on the preprint server bioRxiv, the team describes how they examined 3,663 curated samples of gut bacteria from 1,165 healthy people, aged 20-90, from countries in Europe, Asia, and North America.
