  • this deserved a standing ovation

  • very good, another life saving program..

  • I have searched the internet and not found any info about the side effects of this procedure- does anyone know what usually

    happens through it?

  • Daniel, you ROCK! Where can I volunteer to donate bone marrow with your technology?

  • Excellent presentation.

  • Arggghh... why did he have to say crunch part of the marrow...

  • Cause that's how it is.

  • 3000 years isn't really very long. Have you noticed how fast time is speeding up. Its really slow when you're little, and as you grow time starts to fly by.

    Even if you live infinitely long, its likely that your subjective life will be half over by the time your twenty anyway.

  • WOW amazing food for thought thank you i have for a long time understood the relativity of time but i haven't ever considered its possible effect on an immortal

  • Mmmmm, makes me hungry for authentic Chicago style deep dish pizza - with chunky tomato sauce!

  • Poached bone marrow goes great with bordelaise sauce. MMM, magnifico!

  • well done!!

  • These are the sort of guys i admire, not the wanabe reality stars of the world!

  • Good people with a lot of guts.

  • Over 10 years ago I gave a blood sample as the first step to being a potential bone-marrow donor.

    I heard it was painful, but punctured 200 times?

    Jeez - I don't know if I'm that charitable.

    This looks better - I might go with that - particularly (to be selfish) to bank the stem-cells for my own use later in life.

  • its not selfish its being safe

  • heroes.

  • Certainly makes me more willing to donate, the sheer pain that's involved was about the only thing holding me back. It will probably still be painful but seems to put a whole lot less strain on the body. Great work Dr Kraft.

  • mmmmmmm

  • B17 is also an option for one to fight cancer. Most are lacking vitamin's which can lead to problems over time, eat good, workout, mind and body. Peace

  • "B17 is also an option for one to fight cancer."

    - please take more care when giving medical advice as B17 isn't actually a vitamin. And has only shown marginal effect on laboratory cultured prostate cancer cells. In fact Amygdalin can be dangerous because it can be metabolized into cyanide in the human digestive tract. So in essence it is NOT an option and taking Amygdalin has never shown any effect on cancer in any large scale studies.

  • nice

  • very nice!

  • This is awesome.. yet makes me cringe.

  • does bone marrow regenerate?

  • yes

  • yes

  • yup

  • I never knew bone marrow looked like that. Red like blood. Interesting.

  • Yup, red bone marrow makes erythrocytes and yellow bone marrow makes leukocytes .

  • ugh, watching a needle penetrate the bone makes me throwing up.

  • genius

  • I didn't know Stem cells lived in bone marrow.

  • this will make it less daunting for people to donate marrow. excellent.

  • I wanna dontate bone marrow! how do i go about doing it?

  • Though it is really cool.

    The process to take bone marrow looks awfully painful!!

    This new device hopefully should be less painful...

  • Another progression in medicine. At some point there will be no illness we can't cure. Hopefully they will learn to control the aging process before I die of old age. I want to live forever.

  • Woah chill there Megatron.

  • Can't wait till I can implant my mind into a huge robot body. Please god, let me live to see the day!

  • *loud boomy voice)

    you will my son

    lol, but seriously, science is progressing, but I fear it will turn ugly someday and be our downfall.

    I just saw a video on self learning robots....Most dangerous idea ive ever heard.

  • Comment removed

  • I'm reading 'The Singularity Is Near' by Ray Kurzweil at the moment - he expects similar to what you said by mid century - so keep healthy and save your pennies.

  • I'd be pretty cool with the idea of living 2-3 thousand years, but forever is a long frikkin' time. Basically, I just want to live long enough to see and take part in efficient interstellar travel and extraterrestrial colonization. Jeez, I hope the human species lasts long enough to accomplish that.

  • Well. Obviously you would always have the option to end it. I see no reason to do die before you have to though. I second your hopes.

    Our measly lifespan of 80-90 years is at least much to short and the fact that you're old for half of them is another problem.

  • I wouldn't be able to stand 2-3 thousand years of life. That would surely be hell. Don't get me wrong I love life, but just the fact of living that long is scary.

  • If you were offered on your death-bed a year, a month, a week, of healthy life, do you think you would refuse?

  • No, I wouldn't refuse, but thats completely irrelevant to 2-3 thousand years. It would be nice to live at least 150 years without a significant amount of aging. It would allow us to experience the world more fully without straining ourselves.

  • "No, I wouldn't refuse, but thats completely irrelevant to 2-3 thousand years."

    The point is that you have to say 'no' to the above offer sometime - when it comes to the crunch the second time you get the offer - are you sure you will refuse? Do you think life will become less precious to you after millennia of experience than it is now?

    You want a few decades to experience the world. I would like a few millennia to experience the universe.

  • You're obviously a more knowledgeable man than I for I am a 13 year old boy with no meaning to life as of yet.

  • LOL. Older, certainly - you come across as thoughtful and intelligent - I am sure you will be more knowledgable than me before long.

  • Time feels slower when you're young so there's no wonder the prospect of living for milennia is off putting to you. Give it 10-20 years. When the years starts flying by you will probably want more time.

  • for myself i really cant imagine wanting to live passed 2 or 3 thousand but who knows its incredibly hard to speculate once we convert ourselves to a purely informational state which will likely be the true final destiny of man kind

  • dude, life begins at 800,000

  • Can bone marrow be used to grow the hormones the body loses over time?

  • not yet, but even if it could (by making it the hormone producing kind of cell) there is a further problem that our bodies also eliminate more hormones when we are older.

    fantastic voyage is a great book on this topic, and lots of others more important than this one.

  • Eliminate hormones? Are you sure, isn't it that they stop producing hormones?

  • it doesn't , it only replaces the existing ones. its basically a " life on a support" thing.

  • I thought he was gonna talk about cheese... :p

  • Awesome!

  • Great!

    I had no idea you needed that many iterations. I thought a single extraction, like when taking a blood sample, was sufficient.

  • Amazing stuff. Makes ya wonder why it took 40 years for someone to think of something to relatively simple though...

  • Because it isn't simple.

  • 'it isn't simple'

    -I fail to see how this technology isn't simple by today's standards... Simply put, it's a drill, with a hollow bit, and a bit of surgical wire at the end to 'mix' things up a bit. Run a tube through the hollow bit, and a little vaccuum, and out comes the marrow. If you use power tools like I do, you would see how simple it is. Yes, it's simple, but it's damn Brilliant!

    Again, I'm just surprized that it took as long as it did to come up with it. Smart guy in the video though.

  • The concept is simple but I think you underestimate the implementation.

    The hole is a couple tenths of an inch thick. The 'drill' has to be deflectable and compliant. The axial rotation needs to translate down the curved shaft of the catheter. The 'mixer' needs to free up the cells without damage. The entire catheter needs to be biocompatible. The catheter needs to work in a sealed fluid environment.

    i can go on. but you are right, the technology has existed for some time.

  • 'you underestimate the implementation'

    No I understand. That's why I wrote "Simply put" before I wrote it. I know it's slightly more complex than that, but the idea itself is evidently simple. That's all I meant by it. It's both simple, and also brilliant. Amazing stuff.

  • This looks like something like the Strogg would really appreciate.

  • he invented an ass drill!

  • saying First on a TED video is kinda like bringing popcorn to an opera.

  • But what would be wrong with bringing popcorn to an opera?

    Operas can be long, you know, and only the ignorant are pretentious enough to dress up. It is wise to wear comfortable clothes and get comfortable as well.

  • quick concise to the point and full of useful informational goodness 5 stars.

  • Cool device.

  • What... nobody wrote "first"? Am I on the right channel?

    An amazing medical app, once again, science makes me all tingly inside.

  • lol

  • That's brilliant! Kudos to Daniel Kraft for that brilliant invention and TED for the video!

  • Wow. Amazing what people can do now. I can only imagine how much more useful that would be than the old technique. Especially since it looks a lot less painful, and defiantly less invasive.

  • How can something be so disgusting and amazing at the same time?

  • Kick ass. Good for him. Yay his brain.

  • Medical Science, disgusting and amazing at the same time.

  • Cool.

  • I love medical science.

  • yummy
