Deleting genes could boost lifespan by 60%, scientists say
Following an exhaustive, ten-year effort, scientists at the Buck Institute for Research on Aging and the University of Washington have identified 238 genes that, when removed, increase the replicative lifespan of S. cerevisiae yeast cells. This is the first time 189 of these genes have been linked to aging. These results provide new genomic targets that could eventually be used to improve human health. The research was published online on October 8th in the journal Cell Metabolism.

I hope the red hair, blue eyes, and twin gene are not one of the genes. 😜
ReplyDeleteInteresting. But I still think anywhere between 70 and 90 years is still good innings - good enough for a full life.
ReplyDeleteAre we talking deleting genes? Or deleting imprints of processed food?
ReplyDeleteUnintended consequences lurking?
ReplyDeleteHahahahaha, than look for more of younger vine ;-)
ReplyDeleteIt's always very nice to meet retards who claim that humans == yeast, always fun
References are valuable, thanks.
ReplyDeleteI read about this today! un-capping bottle of white out
ReplyDeleteThe headline is delicious, like the mathematician with an IQ like 130 whose hydrocephalus was belatedly discovered. You look at the head scan, and the thick cranium hides a thickness of gray matter on its inside, encasing a wide empty space filled with fluid. Perhaps neurons can telepathy through such medium:)
ReplyDeleteThere are many angles on the news. Of note is that it only makes sense because these cells bud in such a way that mother and daughter cell are well distinguished - what's not the case of all unicellular organisms and not even in yeasts. What's extended is not the age at which cells die but the age at which they cease reproducing.
ReplyDeleteThere is something paradoxical whatever to this behavior of genes. The base expectation is that natural selection should have removed such genes; that it hasn't calls for an explanation in terms of kin selection, at some point the genes of the mother cells are present in enough daughter cells around that it's optimal to head for grandmother role.
The contemplation of this base expectation and paradox, also leads to a competitor to "survival of the fittest" as the nutshell summary of evolution by natural selection, which is "death is suicidal" -- the point being that when morbid traits are positively traceable to particular genes, if makes these traits comparable to the "ordinary" physiology of life - it gives sense to speak of death as alive. But "survival of the fittest" means such genes will be eliminated by their own action, so that death ceases to be alive (by their mediation) -- death is suicidal.
This observation in turn impacts on the poetic potential of having in French the sounds of "la morale" (morals) guide to "la mort à la mort" (death to death).
