Geneticists claim ageing breakthrough but immortality will have to wait: “Scientists believe that drastically cutting calories triggers a switch in an organism’s behaviour, from growing and being able to reproduce, to a state of stasis in which growth and ageing are put on hold at the expense of reproductive capability, until more food is available. Scientists are now trying to mimic the effect by tinkering with genes in the hope of developing anti-ageing treatments that work without having to cut food intake.”
