‘Young poo’ makes aged fish live longer

‘Young poo’ makes aged fish live longer

Well it's a fish but it makes you wonder right?

The young microbiome ‘transplant’ also had dramatic effects on the longevity of fish that got them: their median lifespans were 41% longer than fish exposed to microbes from middle-aged animals, and 37% longer than fish that received no treatment (antibiotics alone also lengthened lifespan, but to a lesser extent).

And at 16 weeks — old age, by killifish standards — the individuals that received young gut microbes darted around their tanks more frequently than other elderly fish, with activity levels more like 6-week-old fish. By contrast, gut microbes from older fish had no effect on the lifespans of younger fish, Valenzano and his team report.
