Stem Cell Brain Implants Could 'Slow Aging and Extend Life,' Study Shows (theguardian.com) 116

An anonymous reader quotes a report from The Guardian: Scientists have slowed down the aging process by implanting stem cells into the brains of animals, raising hopes for new strategies to combat age-related diseases and extend the human lifespan. Implants of stem cells that make fresh neurons in the brain were found to put the brakes on aging in older mice, keeping them more physically and mentally fit for months, and extending their lives by 10-15% compared to untreated animals. The work, described as a tour de force and a breakthrough by one leading expert, suggests that aging across the body is controlled by stem cells that are found in the hypothalamus region of the brain in youth, but which steadily die off until they are almost completely absent in middle age. Researchers at Albert Einstein College of Medicine in New York hope to launch clinical trials of the procedure soon, but must first produce supplies of human neural stem cells in the lab which can be implanted into volunteers. The study has been published in the journal Nature.

      A lot of those costs are due to things the process could possibly fix. TFS mentions it keeps them physically and mentally fit longer. Care for elderly who are mentally unable to care for themselves is obviously quite a bit more difficult (read: expensive). Someone who can ring the bell when they need help getting to the toilet may be a burden, but it's vastly better than someone who can't.

      Same with the physically fit part. If this implant lets your parent walk up and down the stairs, that's much better than if they can't.

      Cancer, osteoporosis, diabetes and a lot of other medical conditions are still going to be expensive, sure, but solving for assisted or total care would still dramatically reduce costs.

You get to live longer, if your ego does not demand infinite breeding. Now if they extending life but you remain that invalid age, well, why the fuck bother, who wants to be 150 if your body actually behaves like it is 150 instead of say 35(note the reference).

      But, given the population and the cost of geriatric medicine to the economy, is extending human life that much of a good idea?

      The point is not to extend the time you hang around being in poor health, but to give people a longer, healthy (and productive) life. There are reasons to believe that one of the key reasons for our species' success was the fact that we started having grandparents about 30K years ago: https://www.theguardian.com/sc... [theguardian.com] - grandparents not only give those of childbearing age more freedom to gather food etc, they were probably crucial in establishing bonds with other tribes, thus providing an important precondition for a larger society and eventually civilisation. Now-a-days, I think living healthy lives for longer has obvious bebefits - caring for a frail, elderly population is expensive for any society, but taking the frailty out of the equation not only means a great cost saving, it also adds years in which people contribute to society.

      • The point is not to extend the time you hang around being in poor health, but to give people a longer, healthy (and productive) life.

        That might not be the point, but it might be the effect. There are certain issues that are difficult to get around, such as the wear and tear on joints that goes beyond typical body repair processes. If we say increase average lifespan to say 200 years, we are going to need some serious work on our skeletons to replace the calcium phosphate and calcium hydroxylapatite they are composed of along with collagen. It just isn't up to the task of human type activity for that long.

      Exactly what I came to say. There's a point where eternal rest is more enjoyable than continued existence, as many inform older people exclaim. If we legalised euthanasia, and allowed people to choose to die peacefully rather than go through another round of chemotherapy or whatever, there'd be a shit ton of money freed up to spend on people whose quality of life is worth investing in.

    Yeah, while I'd willingly try a (deep!) neural implant of (somebody else's) stem cells that might require a lifetime of anti-rejection drugs in order to live substantially longer, maybe there's a better simpler cheaper faster way.

    In the fine article (I know I know, who reads the articles?), they mention that at least some of the effects are due to miRNAs released by the stem cells. These circulate in the brain fluid and control gene expression throughout the brain. (For those who aren't thoroughly steeped in genetic expression; miRNA stands for micro-interfering RNA, these are short ~20bp sequences of RNA that by precisely complementing a particular DNA sequence them, can "silence" or interfere with them).

    So perhaps a simple cranial injection (ouch!) of miRNAs would be all it takes. In fact, if you make the RNA sequences at home (what, you don't have a DNA/RNA synthesizer?) and a hand drill you could do it yourself! (If you don't have a DNA synthesizer yet, hopefully every school will have one within a decade).
