- www.ted.com Daniel Kraft demos his Marrow Miner -- a new device that quickly harvests life-saving bone marrow with minimal pain to the donor. He emphasizes that the adult stem cells found in bone marrow can be used to treat many terminal conditions, from Parkinson's to heart disease.

quick concise to the point and full of useful informational goodness 5 stars.
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.
Daniel, you ROCK! Where can I volunteer to donate bone marrow with your technology?
That's brilliant! Kudos to Daniel Kraft for that brilliant invention and TED for the video!
I wanna dontate bone marrow! how do i go about doing it?
saying First on a TED video is kinda like bringing popcorn to an opera.
Great!
I had no idea you needed that many iterations. I thought a single extraction, like when taking a blood sample, was sufficient.
Poached bone marrow goes great with bordelaise sauce. MMM, magnifico!
Good people with a lot of guts.
Excellent.
'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.
Woah chill there Megatron.
Good point.
very nice!
does bone marrow regenerate?
This looks like something like the Strogg would really appreciate.
Can't wait till I can implant my mind into a huge robot body. Please god, let me live to see the day!
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.
Awesome!
I didn't know Stem cells lived in bone marrow.
Cool device.
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.
Though it is really cool.
The process to take bone marrow looks awfully painful!!
This new device hopefully should be less painful...
Amazing stuff. Makes ya wonder why it took 40 years for someone to think of something to relatively simple though...
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.
this will make it less daunting for people to donate marrow. excellent.
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.
I love medical science.
It's so interesting!
yes
All of these comments are from 11 years ago
it doesn't , it only replaces the existing ones. its basically a " life on a support" thing.
'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.
I thought he was gonna talk about cheese... :p
Because it isn't simple.
LOL. Older, certainly - you come across as thoughtful and intelligent - I am sure you will be more knowledgable than me before long.
Yup, red bone marrow makes erythrocytes and yellow bone marrow makes leukocytes .
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.
If you were offered on your death-bed a year, a month, a week, of healthy life, do you think you would refuse?
genius
"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.
well done!!
ugh, watching a needle penetrate the bone makes me throwing up.
I am the only here from 2022
This is awesome.. yet makes me cringe.
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.
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.
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.
