Nanotech Motors, Biotransistors, DNA Fractals
FleaPlus writes "The American Institute of Physics has a news bulletin describing a couple of interesting nanotech advances. The first is the smallest electric motor in the world, made by Alex Zettl's group at UC Berkeley. The second is a single-protein wet biotransistor. Additionally, Technology Research News reports on algorithmic self-assembly of DNA Sierpinski triangles, by Erik Winfree's group at Caltech."

While serving my sentence at a former institution, I was severely beaten and gang raped, both orally and anally, by six black inmates . . . . It started by inmate [A] coming by my cell and waking me up at approximately 4:00 a.m. He said he wanted to come in and watch television with me. I said, "No, I'm trying to sleep." He said he's going to the booth and get my door open. I saw him go to the booth and told the booth officer to open my cell door . . . My cell door was not authorized to be opened. By this time, I had turned on my overhead light and heard inmate [A] say to [the officer], "Open #222, so I can get his laundry." I didn't think nothing of it because we've had no prior problems before. I did think it was odd though. So he came in and sat on my bed . . . . About 5 to 10 minutes after that, inmate [B], [C], and [D] came into my cell. Then inmate [D] said, "We want some ass." I said, "I don't think so, I don't play that shit." When he said this, I said to myself, "Oh no! I'm in trouble!" I looked toward the door for an escape route finding it blocked, I went into myself to prepare for the worst. Inmate [D] then said, "Either give it to Jesus or give it up." . . . . It was at this time that the floor officer came by on the bottom tier (I was on the top tier), doing or supposedly doing, his rounds. He noticed the inmates in my cell and asked if everything was all right. Too terrified to answer, I just nodded. [The officer] never came to the top tier during his round. I was then directed back to my bed. Inmate [B] then stood in front of me and pulled out his penis and forced it into my mouth. Inmate [C] then turn his turn. Pulling me to my feet, he then took my boxers off, bent me over and forced his penis inside. Inmate [D] laid on the bed, took my head and forced himself inside my mouth [All four of them, plus one more] took turns anally and orally raping me at the same time. All of them repeatedly did this. Somewhere in the middle of this, inmate [F] entered . . . . [D]uring the rape, I believe it was him that said "suck this dick you white bitch.". . . . [One said:] "If you snitch on us, we'll kill you!!" The other said, "And if you do and you get transferred, you'll still die." At that time, I really believed them, and I still think this today.
Are sooo March 2005. Wake me up when they develop a single protein dry biotransistor.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
Could someone give me a quick summary of all this?
Smallest electric motor is self-explanatory, but... Self assembling DNA... What's that all about?
Wasn't there an article about mini-turbines also, that researchers were planning on using to power small devices, I'm wondering if these nano-motors could be used in the same regard.
Maybe I should go RTFA now.
Here, they're getting slow (even for a Sunday night).
for those of us who aren't fond of arcane geometrical shapes (or Google, for that matter)
So how fast can this biotransistor oscillate?
BOOOOORING let me know when they develop a fully functing nano sized Flux Capacitor so i can put it in my watch and make it run Linux so that when ever i miss something good i can just rewind it.
The first is the smallest electric motor in the world, made by Alex Zettl's group at UC Berkeley. Eventually, this will go into the world's smallest electric planer, which will be used, in part, to create the world's smallest violin. Tragically, this wonder of design will be crushed between the fingers of Steve Buscemi.
Okay, I'm not a scientist, but why would you want a *smaller* vibrating dildo?
nano contact lenses that enable me to see through clothes!!! now that would be an interesting nanotech advance.

362 is enough to penetrate 30 meters of copper. Why not mount this thing on top of a large mountain and snipe some terrorists from 480 miles?

Slashdot is sounding more and more like those search engine spamming sites. But instead of search engines, it's the drooling readers that slashdot is trying to entice with things that aren't really news and aren't really a big deal.
I am not sure if I understand the power density claims. Here is a simple calculation. 20 microwatts in cube of 200nm x 200nm x 200nm will be 20 microwatts in 8 x 10^(-15) cm^3 volume. That will be a power density of 2.5 x 10^9 Watts/cm^3.
Sun's fusion power density is only ~ 2.5x10^(-4) Watts/cm^3 with core temperature around 15.7 x 10^6 K. I can understand that we wouldn't be generating the heat at peak density, but if we generate that high power desnity in nanomechanical system for even any reasonable time - wouldn't it just evaporate unless we find a very fast way of removing the power efficiently ?
Nanotechnology has gotten a reputation for being a flaky area of research. Part of the problem is that the word "nanotech" sounds cool, so people tend to use it without defining what they mean. Eric Drexler originally defined it in terms of machines that worked at the molecular level, i.e., on scales of a few nanometers. The problem is that there are fundamental reasons why it's extremely difficult to construct machines on that scale, and in the 20 years since he published Engines of Creation, basically nothing has happened to realize his original vision. Meanwhile, people have been making smaller and smaller machines via techniques that would never be able to scale down to the scales Drexler had in mind. The wikipedia article distinguishes between "nanotechnology" and "molecular nanotechnology." The Berkeley group's motor, for instance, is clearly on a scale (hundreds of nm) that is not molecular nanotechnology.

Well what else would you call self assembling organic matter? Of course, considering that the average person does this millions fo times per day, it's not exactly something to boast about. I fact I'm doing it right now - the difference is that I'm not putting out a press release.
At first, I thought the DNA assembly-Sierpinski Triangle story was particularly interesting, as a link between real world information storage and the usually unworldly area of fractal geometry. On following the story, it turns out that the error rate is simply enormous (1 to 10%). DNA, in normal use, works about a billion times more reliably than it does here.
You could probably coax DNA to assemble into face centered cubic crystals with a much lower error rate than that. Hell, you might be able to get little figures of Snoopy and Garfield more reliably than these Sierpinski Triangles. This is like proving you could workably rebuild the Golden Gate bridge from Mayonaise and save the tax-payers a fortune, for sufficiently low values of "workable","fortune", and probably "Mayo".

The question is will we get to the point where our brains just can't take it? Will we have to pass such things onto computers, or find a way to enhance our brains to cope with it?
See, I take the opposite view on this. I feel that technology is actually making life a lot easier for our brains. Perhaps not for all of us, but take an average person. You can effectively run much of your life on autopilot. Driving a car, following mindless rules, technology providing cues and such. Really, many of the things that used to occupy time can now be done through automation - or at least are 'outsourced'. I'm of course looking at the middle-class of North America, but still. I think its hard to make a case that the average citizen is overworked and having trouble coping with technology.
Certainly there are cases of people feeling overwhelmed, but I think they are a minority - vocal, perhaps - but still a minority.

OMG... it's the TRIFORCE
The late 1800's and early 1900's saw much more radical change than we experience. Electricity, Sanitation, Railroads, Cars, Airplanes, Telephones, Iron Steam Ships, Antibiotics, Physics and Math Revolutions (Relativity, QM), etc. Life when from Medivial to Modern in something like 50 years.
What we experience is trivial in comparison.
Of course if those cheap nano-assemblers appear than I will take it all back.
It was here and then it was gone. That was a great flamebait article to bring out all the racists and illegals.
Due to excessive bad posting blah blah... shove it Taco. Your mods dont seem to agree with you.

Except its just (nanoscale) DNA molecules, no brains, no eyes, nothing. Its also like a snowflake, in a way.
I also wonder why I bother replying since you won't come back to your post anyway. Mr. A. Coward.I'm still trying to figure out what people mean by 'social skills' here.
It is I suppose some kind of audio-vibratory-physio-molecular transport device?
and still no cure for cancer
This post makes sense
Hi CmdrTaco! Describe yourself for our readers.
I'm 31, 5'1", about 265 lbs, have pretty orange hair and kinda deep-set white eyes. Hey, when I get all dolled up, I look pretty hot and sexy, let me tell ya! I've always had feelings of being a girl, or wanting to be a girl all my life, but I don't plan on having SRS - that means "Sex Reassignment Surgery", i.e. sex change. I've gotta warn ya though, hon: I love sex (lots and lots of it) and I can be as proper and reserved as a little virgin school girl, or as sick and nasty as the worst slut whore you could imagine - and I luv it! Also CowboyNeal, I have a desire to become someone's obedient and submissive bitch-slave. Either a guy who can love me without any hang-ups over my bisexuality and transgenderness or another transgendered "sister".
Your sex drive must make prison more interesting!
Yes, my being transgendered sure does put "spice" in my prison experience. I'm not all the way "out" with everybody, though. There are a few guys who know for sure, and some others who no doubt have their strong suspicions - and many (most) more who would never suspect that I could be "like that". Oh well!
Describe the prison for us.
This is a maximum security prison called Southern Ohio Correctional Facility (S.O.C.F.), more commonly known as "Lucasville" cuz it's in the town of Lucasville, in Scioto County. At present it's Ohio's only maximum security prison, and up until the beginning of 1995, they did house all Death Row guys here, but after the riot they were transferred to Mansfield Correctional (Medium/Close Security) in a special lock-down section there. The electric chair is still here, and whenever they eventually decide to execute someone else again, they'll bring 'em back down here to do it.
Since you're in a maximum security prison, I guess you can't exactly lounge around in a silk teddy and watch Marylin Monroe movies.
No hon, unfortunately I don't get to dress up in here very much, but I do have a chance on a very rare and wonderful occasion to the extreme delight of a few lucky guys (very discriminately chosen) who I've come out to while sharing a cell with 'em. The last guy who got to see CmdrTaco at her feminine finest started to get really "pussy whipped" after only the 3rd time he gave me that delicious dick! Yummy!!! Am I a sexy, naughty bitch, or what?! It's not really hard for me to get all prettied up if I've got the right watercolor markers and other little stuff I use. I can also make some sexy G-string panties and generally work with what little I can get to make myself up simply, yet so sexily & femininely too.
Any Christmas wishes?
As usual, I've been naughty - but nice, so I see no reason why Satan won't bring me a "Hot Skatin' Barbie", some hot, sexy lingerie (lots of it!), some pretty ribbons & bows for my hair, and a ton of make up & stuff!! Oh, and a nice boyfriend who knows how to treat me like the hot, naughty, tranzi-slut-bitch and the sweet wonderful princess that I am, all in one!!!
Have you been incarcerated in any other prisons?
Yes, I've been in other prisons, and also reform schools when I was an unruly, young, little bitch. Whenever I'm not locked up, I'm a rather free spirited person, and liked to travel around and always be on the go. I've prostituted myself lots of times for money to get drunk and high (weed, mostly) food, and other favors that I've needed. Most of that was when I was young and not locked up. I was raped when I was 14 by a black guy who bought alot of stolen stuff from me and my pals. I was "sorta" raped once while in this prison a long time ago.
How long have you been stuck behind bars?
Let's see, so far I've been in prison for 11 years on this sentence, and I was sentenced to 15 to life for murder. It was a drunken bar/street altercation which led to "his" deat
Maybe CMDR Taco is obsessed with nano women for his nano-sized dick. And stories about using 2 centemeter drills to get to the core of the earth. I see a pattern here. But geeze... can we move on to something else?
36 comments above the 1 score threshold in 4 hours, that is about 8 or 9 people an hour having something to say.
And I guess in addition to the funny comment I made, I might as way say something insightful. Am I the only one worried that a much worse version of "What's the trouble with trebbles" can break out. I don't want nano nothing, I want it big enough that I can see it. The potential to make wepons here is too great. Plus, just the whole thing about using Borg technology in humans makes me shudder.

Ned Seeman's NYU lab produced algorithmic self-assembling Wang tiles for cumulative XOR computation a couple of years ago. The application was inspired by suggestions by Winfree that their then-current system, could accomplish the computation. And it has. Glad to see Winfree continuing to explore this cutting edge.

The teams that came up with the electric motor and dna triangles are proudly trumpeted by the poster of the article.
Is the fact that the bio transistor is made outside the USA (in Italy in fact) a good enough reason to not mention the team that made it?
...but can it run Linux??

I believe this level of technology will lead to such devices as the Supository phone. A small 'contact pill' like devices that when lodged in the anal cavity will permanently lock itself to your tail bone and use your bone network to transmit sound to your ear drumbs and pick up your voice from the same. To dial up a number you would simply call out the command into thin air. YOu would hear the computer ask you if you wanted to dial this person or what not. YOU could adjust the settings to vibrate for quit opperation. The phone would get power from your movenments that would cause a tiny magneto to charge the internal lithium cells. YOU would program it using a blue tooth tranciever installed in your pc or by voice command. One step closer to being borgafied. A blue too suppository phone may be quit the thing. LoL Btw guys this is a device in one of my comical scifi stories- NO STealing!...
First post!! I work in a nanotechnology department in England, studying for a PhD. Im pleased to tell you I once used or SEM to draw a tiny micormeter sized phallus on a wafer, complete with testicles and hair. Ill dig out the picture if I can find it.
