Cornell Nanohelicopters Achieve 8rps

Logic Bomb points to "[a] New York Times article [free reg req] detailing this rather incredible bit of technological progress. From the article: 'This is the first true nano machine,' said Dr. Carlo D. Montemagno, professor of biological engineering at Cornell and senior author of the Science paper.' Nuff said." Well, perhaps not -- surely it's not the first tiny mechanical device. Stuff That Matters links to this brief ZDNet coverage of the same thing, a bit more breathless.

  1. Not to be a doomsayer, but... by TKarrde98 · · Score: 3

    Dr. Besenbacher said the perspective piece was not meant as a prediction, but to inspire researchers to brainstorm about the newly discovered phenomenon.

    I suppose that's what you have to say when you speak without thinking first. Someday humans will realize that Ford Prefect was right-- when a human's mouth opens, his brain stops working. (Thank God \. is all done in the fingertips!)

    ************

    Meanwhile, other researchers have been building tiny motors inspired by machinery inside living cells. The so-called biomolecular motors run on adenosine triphosphate, or ATP for short, the same energy-rich molecule that powers chemical reactions within cells.

    Why do I have sudden images of AI, spider-like robots crawling around fields of human batteries?... I'm not usualy technophobic, but this idea really frightens me-- robots so small you can't see them zipping around my bloodstream parasitically thriving on my energy. Yikes!

    Dr. Montemagno's group grafted nickel propellers onto the central shafts of 400 biomolecular motors. Of those, 395 remained motionless, when immersed in a solution full of ATP. But 5 spun.

    I like those odds-- 1.2% chance of an energy sucker. But if they become self-replicating-- well? The story, "Nightmare Number 3" comes to mind (I believe it's by Stephen Vincent Benet?).

      The article in Science describes the propellors as being 750 to 1400 nanometers in length, with shafts 150 nm in diameter. In other words, they're microscale, not nanoscale.

      The ATP-fueled motors, of course, are just F1-ATPase enzyme, straight from bacteria... and the enzyme is indeed nanoscale, at ~8 nm diameter and 14 nm length. But Montemagno didn't build it, just co-opted it.

    "My continuing professional work is on improving the reliability of software. Software is a tool, and as a toolbuilder I must struggle with the uses to which the tools I make are put. I have always believed that making software more reliable, given its many uses, will make the world a safer and better place; if I were to come to believe the opposite, then I would be morally obligated to stop this work. I can now imagine such a day may come." Bill Joy

    nanotech is a tool just as a hammer is a tool. tools can be used for good and bad purposes. just because a tool *may* be used to cause harm is no reason not to use the tool. I can beat you over the head with a hammer, but I can also build a house.

  5. Re:Control by tesserae · · Score: 3
    What's truly interesting is Dr. Montemagno's claim that "this is the first true nano machine" -- considering that what he did was take an enzyme (F1-ATPase, where the "1" is a subscript) which uses adenosine triphosphate (ATP) as an energy source, creating rotary motion as the result. What he did was stick a propellor on the end of the enzyme's shaft... hardly what I'd call creating a nanomachine.

    This is especially true since bacteria already use the enzyme to spin their flagella (for example), to move themselves around. Sort of like taking a car, putting paddlewheels on the axles instead of wheels, and proclaiming that you've developed the "first true self-propelled machine."

    Cute trick, but the hard part -- the nanomotor -- was already built. Nice publicity, though.

  10. nanotech is a billion years old by mangu · · Score: 2
    Or a thousand million years, if you are British. Life is nanotech-based. And it did destroy the world as it was. It turned a carbon dioxide based atmosphere into a highly reactive, oxygen based atmosphere.

    But rogue machines turning amok aren't so dangerous. Nanomachines are extremely fragile, they only survive in their very specific environment. Haven't you read or heard the sentence "biodiversity is endangered"? The potential dangers of nanotech are being considered by the technical people involved, and have been discussed since the nanotech idea was first proposed. Read Eric Drexler's "Engines of Creation", chapter 11, "Engines of Destruction", for instance.

    The concept that scientists and engineers are unaware of the dangers of their research comes from people who get a lot of attention and a steady income by sending alarms to the sensationalist tabloids.

    The most pressing issue that needs to be considered regarding nanotech is the economic changes that will come when you can manufacture anything you need for free at home. The entire manufacturing sector of the economy will disappear, only intellectual property will remain. The only economic product will be software, and we have a lot of people willing to give software away for free. Can you imagine a world like that? I cannot.

  21. Announced today . . . by DeadMeat+(TM) · · Score: 2
    Microsoft today announced the development of Windows NE (Nanomachine Edition). Microsoft is targeting this long-rumored OS, a scaled-down version of Windows CE, to the developing nanomachine market.

    "Now doctors can perform complicated surgery with the reliablility of the Windows (R) platform," Microsoft co-founder Bill Gates announced in a press conference today. "Provided that they pay the appropriate license fees, of course."

    Microsoft has plans to license the OS on a per-machine basis, for a low price of $10.00 a nanomachine. Industry speculators predict that the sheer number of nanomachines required for many surgeries will provide Microsoft with a very large profit margin. Microsoft officials would neither confirm nor deny rampant rumors that license fees would be charged for the future children of users whose lives are saved by these operations.

    Microsoft also announced its plans to market the .NET version of Windows NE, which would allow users to rent Windows NE on a monthly basis. "All we are asking for is a small fee every month for saving a number of lives," Gates told reporters. "Of course, if said fee is not paid, then said life will automatically be revoked by the advanced licensing system of Windows NE."

    However, some of Microsoft's competitors were very vocal in their opposition to Microsoft's announcement. Larry Ellison lambasted Microsoft's announcement, stating that "Microsoft isn't thinking about the future. In the future, medical operations won't be limited to just computers and nanomachines -- ordinary household pens will be able to drill into your skin to perform routine surgery." Not coincidentally, Oracle announced today its intent to develop an OS to power ink, which it plans to market primarily to tattoo parlors worldwide.
