    Default Scientists Discover Mitochondria Control Life Span

    If you think life's too short, then you're not alone. A team of scientists set out to find what it would take to live a very long life and they made important discoveries that bring longer life spans much closer to reality. A new research report featured on the cover of The FASEB Journal, describes how scientists "activated" life extension in the roundworm C. elegans, and in the process discovered a new metabolic state correlating with long life.

    To make this discovery, scientists compared one class of long-lived C. elegans, called the Mit mutants (which have disrupted mitochondrial electron transport chain functionality), with non-mutant wild type C. elegans. Their comparison showed significant metabolism changes, suggesting that their cellular engines had been reconfigured to run on new fuels and to make new waste products, leading to increased lifespans.

    "C. elegans has provided a useful animal model for human biology," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal, "because of their relative simplicity and our understanding of the genes that control their metabolism. Helping these worms to live longer is a proof of concept; indeed much of what we now know about human aging was first worked out in these worms."

    "This research on worms shows that the secret to a long life comes from how we extract energy from our food," commented Weissmann. "With any luck, we'll be able to change human life in the same direction: onward and upward!"

    That's exactly what this world needs, more centenarians.

    Both male and female walruses have tusks and have been observed using these overgrown teeth to help pull themselves out of the water.

    The mustached and long-tusked walrus is most often found near the Arctic Circle, lying on the ice with hundreds of companions. These marine mammals are extremely sociable, prone to loudly bellowing and snorting at one another, but are aggressive during mating season. With wrinkled brown and pink hides, walruses are distinguished by their long white tusks, grizzly whiskers, flat flipper, and bodies full of blubber.
    Walruses use their iconic long tusks for a variety of reasons, each of which makes their lives in the Arctic a bit easier. They use them to haul their enormous bodies out of frigid waters, thus their "tooth-walking" label, and to break breathing holes into ice from below. Their tusks, which are found on both males and females, can extend to about three feet (one meter), and are, in fact, large canine teeth, which grow throughout their lives. Male walruses, or bulls, also employ their tusks aggressively to maintain territory and, during mating season, to protect their harems of females, or cows.
    The walrus' other characteristic features are equally useful. As their favorite meals, particularly shellfish, are found near the dark ocean floor, walruses use their extremely sensitive whiskers, called mustacial vibrissae, as detection devices. Their blubbery bodies allow them to live comfortably in the Arctic region—walruses are capable of slowing their heartbeats in order to withstand the polar temperatures of the surrounding waters.
    The two subspecies of walrus are divided geographically. Atlantic walruses inhabit coastal areas from northeastern Canada to Greenland, while Pacific walruses inhabit the northern seas off Russia and Alaska, migrating seasonally from their southern range in the Bering Sea—where they are found on the pack ice in winter—to the Chukchi Sea. Female Pacific walruses give birth to calves during the spring migration north.
    Only Native Americans are currently allowed to hunt walruses, as the species' survival was threatened by past overhunting. Their tusks, oil, skin, and meat were so sought after in the 18th and 19th centuries that the walrus was hunted to extinction in the Gulf of St. Lawrence and around Sable Island, off the coast of Nova Scotia.

    we need socially functioning centenarians, not those Alzheimer's ridden 80 something guys that can't even eat for themselves

    You won't benefit from this discovery unless they use it to clone you a new body.

    Plus the human population would explode if we could live longer unless we could somehow control our sperm and eggs.

    This.

    As long as I would like to live a long and healthy life beyond 100, unless we get a handle on our population this would not be prudent.

    I never really had a problem with China's 1 child policy. Although it seems oppressive they were actually just doing what needed to be done. The downside is that a demographic shift toward the older generation may mean hard economic times in the future.

    How exactly could a centenarian be an "80 something"?

    if you're going to live longer you want to age slower.

    50 would need to be the new 35, and 70 the new 50.

    it sucks to be 20 and realize you're basically dead by 50. It also sucks that people managed to conquer entire empires by the time they were 33 and yet many of us don't even own our own home by then

    I want to still have some expectation and something to strive for at 50.

    Basically dead by 50? Only if you completely ruin your body, I doubt most 50 year olds I know would say they are "basically dead".

    Extending lifespan could be very useful if people are also age more slowly as it would mean that they would be able to work for longer (although if the proportion of non-worked years to worked years was the same, then this is nullified).
    As long as I would like to live a long and healthy life beyond 100, unless we get a handle on our population this would not be prudent.
    Most global population growth comes from developing countries, which in all probability would be the last people to receive the benefits of an increased lifespan. Most western countries have ageing populations and some are declining in population so longer lifespans would be beneficial to them.

    The real goal here is to be 20 years old for a hundred years.

    basically if you consume less energy, your mitochondria generate less fre radicals slowing genetic damage caused by this, fairly obvious and it does not help, we don't notice the side effects in worms, but in higher life forms, it will cause loss of appetite and in general less activity, a diminished sexual urge, does not sound like a solution.

    Starved lab rats live longer than well-fed lab rats, and many cultures which adhere to periodic fasting protocols have higher average longevities (and consequently lower metabolisms) than us Western fat-fatties. Toxins accumulate in fats, too, so the lean life is def the way to go.

    Loss of appetite is no biggie, we're generally less active anyway, and who needs sexual urges when you're logging 10+ TWC posts a day?!?

    Live fast, die trying...or simply up your post count w more complaints about how there's no time to do things.

    Well, mitochondrias are, I think, the greatest thing since sliced bread, and well, there is still many things to learn from them. I´m really not surprised if we end up having contorl over our life rates and metabolism after more and more extensive research on them.
    Do check my AAR "The Proud Blood of Germania"
    Formerly known as JerichoOnlyFan.
    And my other AAR: "The Black Serpent"

    This is something that has always confused me. If we have an increased metabolism, we are predisposed to die early, correct?

    Well then wouldn't exercise (which is obviously good for many different reasons) be contraindicated?
    Or does it have something to do with a basal metabolic rate?


    Lower metabolism=easy weight gain, less body activity= larger person=less healthy person. Typical outlook on this I think.
    Higher metabolism=thinner person etc etc= healthier person.

    I think maybe that notion is confusing me with what I'm reading here.

    Higher metabolism burns more fuel, causes more wear on the mitochondria. The problem is we eat too much, so low metabolism people who eat too much get fat and unhealthy.
