    Hall's team adopted an innovative approach to investigating Dirac's theory, creating and identifying synthetic magnetic monopoles in an artificial magnetic field generated by a Bose-Einstein condensate, an extremely cold atomic gas tens of billionths of a degree warmer than absolute zero.

  • Neural networks -- collections of artificial neurons or nodes set up to behave like the neurons in the brain -- can be trained to carry out a variety of tasks, often having something to do with pattern or sequence recognition. As such, they have shown great promise in image recognition systems. Now, research coming out of the University of Hong Kong has shown that neural networks can hear as well as see. A neural network there has learned the features of sound, classifying songs into specific genres with 87 percent accuracy.
  • Similar networks based on auditory cortexes have been rewired for vision, so it would appear these kinds of neural networks are quite flexible in their functions. As such, it seems they could potentially be applied to all sorts of perceptual tasks in artificial intelligence systems, the possibilities of which have only begun to be explored.

    Let me guess, you came across this while looking into Memristors? :) If not, here's the connection: Memristor minds: The future of artificial intelligence http://www.newscientist.com/article/mg20327151.600-memristor-minds-the-future-of-artificial-intelligence.html ( if you don't have access to the full NewScientist article, there's a mirror here: http://www.mannkal.org/downloads/guests/memristormindsthefutureofartificialintelligence.pdf )

  • The technology was originally developed to handle coding of control code for spacecraft swarms, but it is broadly applicable to any commercial application where rule-based systems development is used.

    This is related to the "Verified Software" item in NewScientist's list of ideas that will change science. At the link below you'll find the text of the patents being auctioned: http://icapoceantomo.com/item-for-sale/exclusive-license-related-improved-methodology-formally-developing-control-systems :) Patent #7,627,538 ("Swarm autonomic agents with self-destruct capability") makes for quite an interesting read: "This invention relates generally to artificial intelligence and, more particularly, to architecture for collective interactions between autonomous entities." "In some embodiments, an evolvable synthetic neural system is operably coupled to one or more evolvable synthetic neural systems in a hierarchy." "In yet another aspect, an autonomous nanotechnology swarm may comprise a plurality of workers composed of self-similar autonomic components that are arranged to perform individual tasks in furtherance of a desired objective." "In still yet another aspect, a process to construct an environment to satisfy increasingly demanding external requirements may include instantiating an embryonic evolvable neural interface and evolving the embryonic evolvable neural interface towards complex complete connectivity." "In some embodiments, NBF 500 also includes genetic algorithms (GA) 504 at each interface between autonomic components. The GAs 504 may modify the intra-ENI 202 to satisfy requirements of the SALs 502 during learning, task execution or impairment of other subsystems."

    bit confused about what they actually have achieved so far but sounds like it might turn out to be interesting. "The scientists first infiltrated the leaves of Anemone vitifolia -- a plant native to China -- with titanium dioxide in a two-step process. Using advanced spectroscopic techniques, the scientists were then able to confirm that the structural features in the leaf favorable for light harvesting were replicated in the new TiO2 structure. Excitingly, the AIL are eight times more active for hydrogen production than TiO2 that has not been "biotemplated" in that fashion. AILs also are more than three times as active as commercial photo-catalysts. Next, the scientists embedded nanoparticles of platinum into the leaf surface. Platinum, along with the nitrogen found naturally in the leaf, helps increase the activity of the artificial leaves by an additional factor of ten."

    "We have applied artificial intelligence in many ways, but if you're really going to implement it," Gonzalez said in a recent interview, "the only way to do it is to do it though some sort of embodiment of a human, and that's an avatar."

BIO NAN carbon muscles

shared by dejanpetkow on 18 Oct 11 - No Cached
  • Actuator materials producing rotation are rare and demonstrated rotations are small, though rotary systems like electric motors, pumps, turbines and compressors are widely needed and utilized. Present motors can be rather complex and, therefore, difficult to miniaturize. We show that a short electrolyte-filled twist spun carbon nanotube yarn, which is much thinner than a human hair, functions as a torsional artificial muscle in a simple three-electrode electrochemical system, providing a reversible 15,000° rotation and 590 revolutions/minute. A hydrostatic actuation mechanism, like for nature’s muscular hydrostats, explains the simultaneous occurrence of lengthwise contraction and torsional rotation during the yarn volume increase caused by electrochemical double-layer charge injection. Use of a torsional yarn muscle as a mixer for a fluidic chip is demonstrated.
