Aging Reversed In Mice

Hugh Pickens writes "The Guardian reports that scientists claim to be a step closer to reversing the aging process after experimental treatment developed by researchers at Harvard Medical School turned weak and feeble old mice into healthy animals by regenerating their aged bodies. 'What we saw in these animals was not a slowing down or stabilization of the aging process. We saw a dramatic reversal – and that was unexpected,' says Ronald DePinho, who led the study. The Harvard group focused on a process called telomere shortening where each time a cell divides, the telomeres are snipped shorter, until eventually they stop working and the cell dies or goes into a suspended state called 'senescence.' Researchers bred genetically manipulated mice that lacked an enzyme called telomerase that stops telomeres getting shorter causing the mice to age prematurely and suffer ailments, including a poor sense of smell, smaller brain size, infertility and damaged intestines and spleens. When the mice were given injections to reactivate the enzyme, it repaired the damaged tissues and reversed the signs of aging raising hope among scientists that it may be possible to achieve a similar feat in humans – or at least to slow down the aging process."

      Just inject some telomerase and it'll be back in its prime. Also, cancerous.

      ...Also, cancerous.

      Might be not much of a problem, in the range of a lifespan typical for a mouse. For us OTOH...

      But it's good to see that biological neural networks being part of computer known as Earth work on upgrades of their true rulers.

    It was probably the unexpected attention that the elderly mice got, that made them feel happy and youthful. That, and a placebo effect.

    They've already done this with dolphins. It involves feeding them seagulls. Unfortunately, the lead scientist was arrested when he stepped across a lion sleeping in the doorway to the lab, after catching a few seagulls.

    The charge: transporting gulls across a staid lion for immortal porpoises.

    Assuming you know you are to live forever, what's the rush in breading children?

    Well, if you want to live forever, that makes a lot of sense. Grilled is healthier than fried.
