Stinky diet could be the fountain of youth
RUMOURS of the fountain youth have taken a disgusting twist after scientists discovered older fish live longer by eating the poo of their younger generation.
Geneticist Dario Valenzano and his colleagues found that African turquoise killifish, one of the shortest-lived vertebrates on the planet, could extend their time by consuming the microbes from the faeces of younger fish.
Killifish sexually mature at three weeks and kick the bucket in just a couple of months!
But the team at the Max Planck Institute for Biology of Ageing in Germany found that nine-and-half week-old killifish, a revered senior to many juniors, lived around 40 percent longer and swam more actively if they followed the putrid diet.
"The paper is quite stunning. It's very well done," Biologist and geneticist Heinrich Jasper said according to Nature.
Similar 'young blood' experiments that join the circulatory system of rats also found the young rodent can improve the health of its older relative.
