The prototype of the groundbreaking computing system, described in an article published in the prestigious scientific journal Nature, signifies a significant step forward in the level of complexity of computer circuits that will contain synthetic nanometric components. The system is also an advance since these tiny nano-circuits can be programmed electronically to perform a number of simple invoicing and logical operations.

"This study represents a tremendous leap forward in the degree of complexity and activity of circuits built in a "bottom-up" manner, and demonstrates that this method, which is very different from the way in which commercial circuits are built today, could lead to the acceptance of nanoprocessors and other future integrated systems," says the lead researcher Charles M. Lieber of Harvard University's Department of Chemistry and Chemical Biology.

The research findings are a consequence of advances in the design and synthesis of nanowire type building blocks. These nanowire components now demonstrate the reproducibility required to build functional electrical circuits along with the possibility to do so in sizes and material complexity that were difficult to achieve in the past using standard "top-down" approaches. Moreover, this architecture is fully scalable, enabling the development of larger and more efficient nanoprocessors.

"For the past 15 years, researchers working in the field of carbon nanowires and nanotubes, as well as other nanostructures, have been working hard to build even the simplest circuits, due to the differences in the properties of the different nanocomponents," says the lead researcher, professor of chemistry . "We have been able to show that this limitation can now be overcome and we are enthusiastic about the prospects of utilizing this bottom-up biological construction method in the development of future electronic components."

Another important feature of the system is the fact that the electrical circuits inside the nanoprocessor operate using low energy, since the nanowires are composed of non-volatile transistor switches. This means that, unlike the transistors found in regular microcomputer circuits, once the nanowire transistors are programmed, they do not require any additional electrical energy to store the memory in them.

"Thanks to their smallest size and low energy requirements, these innovative nanoprocessor circuits are building blocks that could enable the development of an entirely new family of electrical sensors and electronic equipment that are much smaller and lighter in weight," explains one of the researchers.

"This innovative nanoprocessor represents an important milestone towards the realization of the vision of a nanocomputer presented 50 years ago by the physicist Richard Feynman, adds one of the researchers.

  1. Why is this newspaper characterized by talk style like idiot, donkey, etc.
    What message does a person who uses these terms want to convey?
    ego, ego How exactly can you convince the other side with such terms.

  2. I'm writing under the same name I've always written under, which also happens to be my real name. There is a chance that older people on this site remember me. For example here:

    I haven't visited the site in a long time, and I don't know which of the idiots on duty you associate me with (Ezekiel? Spirit?).
    If you thought I was Ezekiel, then the absence of the Lord at the end of her face in the male (such as her decision and not her decision) should have betrayed the fact that it was someone else. Anyway, I assigned you to one of them.

  3. My priceless and chatty friend, I will not stoop to your low level. By the way, why don't you write under the usual familiar name that you usually write under on the science website? what are you afraid of? Everyone knows who you are.

    Keep rambling (as usual) we've already learned how to deal with your arrogant and disgusting comments.

  4. 10 - an idiot, with all the signs.

    1. Do you "really" like to read? Exactly compared to whom? Compared to me? Why did you decide that I don't like reading news on these topics?
    2. You want to read - read. Am I preventing you from reading? you can read Although you won't understand much, because you also read my comment and didn't get anything out of it. I talked about the need to curb the shouts of the "singularities!!!" after reading the article.

    And now you can comment another stupid comment in the procedure. Cheers!

  5. Is it true Adi? Your message also looks very pathetic, so maybe you should also sit quietly for a while.

    I actually like reading about these areas, who are you to shut people up.

  6. But to shout "Singularity!!!" Any information about development in the field of electronics and neuroscience is trite.
    Do you foresee a singularity in 20 years? Good. So sit tight for the next 15 years. It looks pathetic.

  7. Correction - "take into account" of course and not "so into account" (this is probably the time)

  8. Tal, thank you for trying to lower my expectations, and I certainly take into account the possibility that I'm wrong, but I think the chance of that is quite low.

    To say that technological progress will suddenly stop is like looking at a speeding train or a ball rolling down a steep slope and expecting them to suddenly screech to a halt for no apparent reason.

    The arguments you listed are not really relevant - I think so, since time immemorial the majority of the earth's population has lived in the darkness of the Middle Ages, but this did not hinder the spearhead of the scientists to lead towards scientific technological progress and for technology to develop at a rate that is only accelerating day by day for more than 100 years, despite 2 World wars and dozens of other regional wars, economic crises and what not, all these did not affect the rate of progress at all.

    In my opinion, there is no logical reason in the near term (tens of years ahead) that the amazing technological development that we see today will suddenly stop, the explanation for this is that this development does not depend on this or that specific company or on a single invention of a single person, the guiding principle here is that new technologies are constantly being created which Technological progress is accelerating more and more, there are no stops unless there is a catastrophe on a global scale that will destroy most life here like a meteor that will collide with the earth or a world-wide nuclear war.

    For example, the human genome project reached the halfway point after 7 years of hard work and the scientists managed to crack only 1% of the complete sequence, the skeptics claimed that it would take hundreds of years to finish the sequence and according to the rate of decoding at that point in time they were really right - but as Kurzweil predicted the progress is exponential, new technologies were created who accelerated the rate of progress even more and indeed after a year 1% became 2%, then 4%... 8%…. 16%…. 32%…. 64%…. As expected, after 7 years we reached 100% and the project was successfully completed, right on time.

    The Internet is another example of a new technology that creates another technological acceleration, suddenly scientists from all over the world who previously had never heard of each other can now collaborate and go through joint projects together, in this way scientific research progresses at a much faster rate, and add to that the power of computers that doubles per year, more and more accurate simulations of processes, processing huge amounts of information, automation, robotics, new materials, new tools and much more...

    Brain research is already yielding practical products in the field, people manage to operate robotic hands and electrical devices using only thought, scientists have managed to decipher images directly from the cerebral cortex, there are already initial prototypes of bionic eyes that connect directly to the brain for blind people... just think where we will be in 20 And in 30 years from today, and so taking into account that, as mentioned, the rate of progress is accelerating day by day and year by year.

    I think you got the point.

    Again, I may be wrong, but it seems to me that my evidence on the subject is sufficiently controlled.

  9. The drifting on the wings of exciting progress is certainly understandable to me since I am also a super geek, but take the brakes into account and include them in your equations. A huge part of the world's population is still in the darkness of the cultural Middle Ages (Africa) and refuses to walk hand in hand with the enlightened West towards its dreams, pollution of the environment as a derivative of almost every technological development, one and another mental distress that the modern lifestyle brings with it. For every movement in one direction, there is a counter movement in the other direction, and this should be taken into account. It is impossible to see only a narrow aspect of reality, because it is (alas) complex and usually does not listen to our predictions. Take into account that the future may not be as you hope it will be, that way you may save yourself from discouragement, disappointment and frustrations.

  10. The stupid belief about the year 2012 is based entirely on baseless nonsense, even the descendants of the Mayans who live today in the USA declare that it was not and was not created and that none of their people predicted that the end of the world would come on this date, even the prophecies of Nostradamus have nothing to do with the subject.

    The prediction about the singularity is based on evidence that is in front of your eyes, you just have to open your eyes and see where we are going.

    Look at the dizzying pace at which technology advances, what yesterday was considered science fiction today is already reality, sophisticated iPhones that look like similar devices shown 30 years ago in science fiction movies pale in comparison, automatic face recognition is already in almost every camera today, an artificial intelligence computer that beats the champions of all time In entertainment television knowledge, identifying objects in a picture, being able to tell the difference between a dog and a cat (they said that a computer would never be able to do this) and much more. Add to that the enormous progress in the field of brain research and in the field of nanotechnology, the computers that double their power from year to year, and it only matters where this leads us in 10-20-30 years from now.

    I think the general trend is very clear.

  11. All the evidence also shows that the end of the world will come in 2012, right? Come on. If the singularity becomes a reality in the future I will be among the first to join in the celebration, but wiser than me have already said "the prophecy was given to fools". There is evidence for everything. Be aware of when you turn whisperings and inner personal longing into a firm public statement. With all due respect to Kurzweil and there is respect, Nostradamus must also have sounded to his contemporaries as a man who knew what he was talking about.

  12. And you are wrong.

    This is not a hallucination and it is not a false prophecy, all the evidence clearly shows that we are rapidly approaching the period in question known as singularity, you and others like you insist on burying your head in the sand and not seeing reality and what we are going towards.

    "Machines heavier than air will never be able to take off"

    (don't remember who the idiot said that)

  13. To all the believers of the singularity cult - I see your digs everywhere on the web. When will you understand that there is a principle in the universe called "balance". The delusional utopia you are trying to push to everyone is simply embarrassing and does not add respect to you. Release already.
