UCLA Biologists Delay the Aging Process In Fruit Flies 82

An anonymous reader writes:Life scientists at UCLA have located a gene in fruit flies which, when intentionally activated, increases lifespan by about 30%. The gene (called AMPK) is normal important as an energy sensor, usually triggered by cells with low energy levels. By triggering it at other times, the researchers slowed the fruit flies' aging process (PDF), even beyond the organ system in which the triggering occurred. "Walker said that the findings are important because extending the healthy life of humans would presumably require protecting many of the body's organ systems from the ravages of aging — but delivering anti-aging treatments to the brain or other key organs could prove technically difficult. The study suggests that activating AMPK in a more accessible organ such as the intestine, for example, could ultimately slow the aging process throughout the entire body, including the brain."

      That's really interesting! There's a common genetic disease called myoadenylate deaminase deficiency [wikipedia.org] that explains a lot of fatigue issues - fibromyalgia, chronic fatigue, and whatnot . It's interesting to see correlations and effects of excess AMP discussed so thoroughly!

      Pour vinegar into a bowl. Add a bit of liquid soap, to lower the surface tension. Place it next to the place where you have your fruit fly infestation and wait a day or two.

        So apparently you CAN catch more (fruit) flies with vinegar than with honey?

      • To get rid of fruit flies I use a glass jar with an apple core inside and half a bottle of beer (dutch lager, but any beer should work). Put a piece of plastic over the top; secure it tightly with an elastic band and poke tiny holes in it with a toothpick. Sit it out near the fruitflies before work and when you get home 99% of them will be gone. The only drawback is that you waste half a beer on these little pests. But at least you can enjoy the other half in peace.
        • The same thing works just as well without the beer. I suppose the beer probably helps to kill them, but just the apple core and plastic do the job: the apple attracts them (I find a banana works better) and leads them through the holes in the plastic, but then they can't find their way back out so they just fly around inside the jar.

          When all (or nearly all) the flies are inside the jar, I just put it under the tap and run water over it until it fills up through the holes. Then leave it for a few minutes t

          • I originally tried with with just fruit and it wasn't very effective. After adding the beer, it was quite effective.
          • When all (or nearly all) the flies are inside the jar, I just put it under the tap and run water over it until it fills up through the holes. Then leave it for a few minutes to drown them all, and dump it down the sink.

            You can just use some apple cider vinegar with a drop of detergent and skip the labor part (just take the plastic off and dump the mess down the drain). Refill & rekill.

      You can make similar argument for any life-saving treatment, for example cardiac-health related. Any serious heart-related issue used to be terminal, but we largely addressed this and in process greatly increased average lifespan. Now, if you get to a hospital in time you likely to survive.

      Technically, your conclusion is invalid due to hidden premise tied to your Premise 1. What you are trying to implicate with your hidden premise is that life-extending treatment will be forever unaffordable to masses.

      All of your premises assume that the ideas of "Haves" and "Have nots" are even valid. I would, ultimately, say those ideas are incorrect. No one "gets out alive" so to concentrate on that which cannot be kept is ultimately unwise. The idea that "those that die (or live) with the most toys win!" is quite ignorant. The idea that having or not having something is improving or worsening your life is a waste of good time. It's all relative and therefore mental gymnastics at its worst. Time to Wake up.

    • Premise 5: If unchecked, stagnant wages relative to inflation are going to exacerbate the current US status-quo in terms of younger working adults competing with Boomers who refuse to retire and becoming lower-wage workers who become "disposable labor."

      I like your format, but there is a lot of assumption in this premise. I'd like to see it written out with more support, because historically where more labor is available, more jobs are created (although sometimes it takes time). Sometimes the jobs are silly things, like hiring someone to clip your toenails, but they're there.

    It's the sound of the fruit flies that reside in my kitchen cheering like mad, they apparently read Slashdot too.

    They're getting intelligent too, the other day - one of them discovered that beer/vinegar + dish-washing liquid is dangerous, so only ONE of the little buggers died - the rest steer towards my beer bottles the SECOND I open it, I swear to you - these bastards have developed some sort of high end technology for seeking my beer, chocolate or any fruit I have laying around. Their targeting systems should be adopted by the military, they're more goal oriented than a group of old people at the mall fighting over the last piece of meat.

    I'm going down to the kitchen right now to whack a few of the fat bastards.

      Slowing the aging process doesn't add 20 years of the worst health at the end of the life but would extend each portion of the process.

      IE, if the aging process was truly slowed 30% you'd get 30% longer years at 30, 40, 50 or whatever, not 20-25 years extra in the shape you'd be at 90.
