[offsite:ght4tpfb]Scientists at IBM are experimenting with using DNA molecules as a way to create tiny circuits that could form the basis of smaller, more powerful computer chips.
The company is researching ways in which DNA can arrange itself into patterns on the surface of a chip, and then act as a kind of scaffolding on to which millions of tiny carbon nanotubes and nanoparticles are deposited. That network of nanotubes and nanoparticles could act as the wires and transistors on future computer chips, the IBM scientists said.
For decades chip makers have been etching smaller and smaller patterns onto the surface of chips to speed performance and reduce power consumption. The fastest PC chips today are manufactured using a 45 nanometer process, but as the process dips below 22 nanometers in a few years, the assembly and fabrication of chips becomes far more difficult and expensive, said Bob Allen senior manager of chemistry and materials at IBM Research.
The new technique builds on work done several years ago by Paul Rothmund, a scientist at the California Institute of Technology, who figured out that DNA molecules can be made to "self-assemble" into tiny forms such as triangles, squares and stars. The approach takes advantage of DNA's natural ability to incorporate large amounts of complex information that can be applied to different types of activities.
To make a chip, the scientists first create lithographic templates -- the patterns from which circuits are made -- using traditional chip making techniques. After, they pour a DNA solution over the surface of the silicon and the tiny triangles and squares -- what the scientists call DNA origami -- line themselves up to the patterns etched out using lithography.
The IBM scientists, working with Rothmund, then figured out how to layer millions of nanotubes or nanoparticles over the DNA scaffold, where they adhere to form tiny integrated circuits.
"If we can properly, with incredible precision, place these little origami on the wafer surface, then you can use the properties of DNA to generate nanocircuit boards," Allen said.
The ability for the DNA structures to self-assemble is a key element needed for achieving greater precision in the design and manufacture of chips, said Greg Wallraff, an IBM research scientist and co-author of a paper about their achievements.
"The degree of difficulty of nanofabrication is going up rapidly," Wallraff said.
While the technology shows promise, it is years away from practical use, the scientists warned. "It's too early to say whether this will be a game changer," Allen said. "But we're pretty enthusiastic about the potential of this technique."
If it works as planned, it could lead to a new way of fabricating features on the surface of chips that allows semiconductors to be made even smaller, faster and more power-efficient than they are today.
A paper describing the scientists' achievements was due to be published Sunday in the journal Nature Nanotechnology.[/offsite:ght4tpfb]

Nice!!!!! :shock:
Cool post Kiwi!
I love reading this kind of stuff. It's amazing how far we've come since computers started out (the size of a whole office area) to what we have today. I've said it before, and will again...I wouldn't put anything past the guv, and all the hidden techs they've been holding out on the populous to date. I'd imagine they'd have created this stuff years ago, and are NOW just revealling the goods to us.
Wouldn't it be something if the size of one of our lap tops or desktops was shrunk down to the size of a few nanos?

"If we can properly, with incredible precision, place these little origami on the wafer surface,They're pissing up a rope. They're right in their choice of organic material but wrong in the application. They're stuck in the world of silicone. The conscious system will be a wet system. What all computer scientists are modeling is a living brain. The problem is that that are unimaginative. Their thinking is two dimensional. Their 'etched surfaces' are traps analogous to Kantian categories but their machines are essentially toys.

....now I could be wrong here, but Im gonna smite that :idea:

...getting a feeling of night-jevu here,..........cog, do you remember the young guy, back in the 80's who was touted at teh time as being the new "genius" on the block with his nano-technology claims?.....think he was east european descent?......after many months of arse-kissing there came a flurry of "fraud" claims, I followed the story through "new scientist", cant remember the guys name, the whole story just melted off the radar, but the current line of nano research sounds quite familiar..... can any-one throw some light on it ? :scratch:
where will it end?

Jan Hendrik Schön (born 1970) is a German physicist who briefly rose to prominence after a series of apparent breakthroughs that were later discovered to be fraudulent.[1] Before he was exposed, Schön had received the Otto-Klung-Weberbank Prize for Physics in 2001, the Braunschweig Prize in 2001 and the Outstanding Young Investigator Award of the Materials Research Society in 2002.
The Schön scandal provoked discussion in the scientific community about the degree of responsibility of coauthors and reviewers of scientific papers. The debate centered on whether peer review, traditionally designed to find errors and determine relevance and originality of papers, should also be required to detect deliberate fraud.
[edit] Rise to prominence
Schön's field of research was condensed matter physics and nanotechnology.[2] He received his Ph.D. from the University of Konstanz in 1997. In late 1997 he was hired by Bell Labs.
In 2001 he was listed as an author on an average of one research paper every eight days[2]. In that year he announced in Nature that he had produced a transistor on the molecular scale. Schön claimed to have used a thin layer of organic dye molecules to assemble an electric circuit that, when acted on by an electric current, behaved as a transistor. The implications of his work were significant. It would have been the beginning of a move away from silicon-based electronics and towards organic electronics. It would have allowed chips to continue shrinking past the point at which silicon breaks down, and therefore continue Moore's Law for much longer than is currently predicted. It also would have drastically reduced the cost of electronics.
[edit] Allegations and investigation
As recounted by Dan Agin in his book Junk Science, soon after Schön published his work on single-molecule semiconductors, others in the physics community alleged that his data contained anomalies. Professor Lydia Sohn, then of Princeton University, noticed that two experiments carried out at very different temperatures had identical noise.[2] When the editors of Nature pointed this out to Schön, he claimed to have accidentally submitted the same graph twice. Professor Paul McEuen of Cornell University then found the same noise in a paper describing a third experiment. More research by McEuen, Sohn and other physicists, uncovered a number of examples of duplicate data in Schön's work. This triggered a series of reactions that quickly led Lucent Technologies (which ran Bell Labs) to start a formal investigation.[3]
In May 2002 Bell Labs set up a committee to investigate this affair, with Professor Malcolm Beasley of Stanford University as chair.[4] The committee obtained information from all of Schön's coauthors, and interviewed the three principal ones (Zhenan Bao, Bertram Batlogg and Christian Kloc). It examined electronic drafts of the disputed papers which included processed numeric data. The committee requested copies of the raw data but found that Schön had kept no laboratory notebooks. His raw-data files had been erased from his computer. According to Schön the files were erased because his computer had limited hard drive space. In addition, all of his experimental samples had been discarded, or damaged beyond repair.[2][4]
On September 25, 2002, the committee publicly released its report.[4] The report contained details of 24 allegations of misconduct. They found evidence of Schön's scientific misconduct in at least 16 of them. They found that whole data sets had been reused in a number of different experiments. They also found that some of his graphs, which purportedly had been plotted from experimental data, had instead been produced using mathematical functions.[4]
The report found that all of the misdeeds had been performed by Schön alone. All of the coauthors were exonerated of scientific misconduct. This sparked widespread debate in the scientific community on how the blame for misconduct should be shared among co-authors, particularly when they share significant part of the credit. [4]
Bell Labs fired Schön on the day they received the report. It was the first known case of fraud in the Labs' history.[citation needed]
[edit] Aftermath and sanctions
Schön acknowledged that the data were incorrect in many of these papers.[4] He claimed that the substitutions could have occurred by honest mistake. He admitted to having falsified some data and stated he did so to show more convincing evidence for behaviour that he observed.
Experimenters at Delft University of Technology and the Thomas J. Watson Research Center have since performed experiments similar to Schön's. They did not obtain similar results.[2] Even before the allegations had become public, several research groups had tried to reproduce most of his groundbreaking results in the field of the physics of organic molecular materials without success.[3][5]
Schön returned to Germany and took a job at an engineering firm.[5] In June 2004 the University of Konstanz issued a press release stating that Schön's doctoral degree had been revoked due to "dishonourable conduct". Department of Physics spokesman Wolfgang Dieterich called the affair the "biggest fraud in physics in the last 50 years" and said that the "credibility of science had been brought into disrepute".[6]
In October 2004, the Deutsche Forschungsgemeinschaft (DFG, the German Research Foundation) Joint Committee announced sanctions against him. The former DFG post-doctorate fellow was deprived of his active right to vote in DFG elections or serve on DFG committees for an eight-year period. During that period, Schön will also be unable to serve as a peer reviewer or apply for DFG funds.[7]

We'd prefer that you include all the information, Mr. Kiwi.
He admitted to having falsified some data and stated he did so to show more convincing evidence for behaviour that he observed. By virtue of that experience, Mr. Schön is currently an award winning senior correspondent for BE News Corp, LLC of Denver, Colorado and is heading up that organization's advocacy of the Boycott Whole Foods movement.

Down this road is where the machines (as we call them) take over. Enter the Matrix.
This is the most reasonable explanation of the UFO activity if it is not actually terrestrial. The predominate 'intelligent' activity in the universe might not be what we would tend to call living creatures.

and with that the argument over the utility of DNA in computer chips is resolved. thank you jeezzzizzzzz. i was a little worried we were on the wrong tangent.
I think we can once again realize that lawyers can screw up any and every thing.
