Blueprint for an artificial brain: Scientists experiment with memristors that imitate natural nerves Scientists have long been dreaming about building a computer that would work like a brain. This is because a brain is far more energy-saving than a computer, it can learn by itself, and it doesn't need any programming. Privatdozent [senior lecturer] Dr. He will be presenting his results at the beginning of March in the print edition of the Journal of Physics published by the Institute of Physics in London. Memristors are made of fine nanolayers and can be used to connect electric circuits. Like synapses, memristors learn from earlier impulses. Andy Thomas explains that because of their similarity to synapses, memristors are particularly suitable for building an artificial brain -- a new generation of computers. Thanks to these properties, synapses can be used to reconstruct the brain process responsible for learning, says Andy Thomas. If the neutral bell-ringing stimulus is introduced at the same time as the food stimulus, the dog will learn.
How To 3D Print: Turning Virtual Geometry Into Physical Products 3D printing is poised to revolutionize how we consume and make goods—one day in the future, you might design some housewares on your computer and 3D print them instead of going to IKEA to buy new stuff. One of its design benefits is the technology’s ability to create elaborate forms that would be nearly impossible using traditional techniques like molding and casting. To design something to be 3D printed is to think differently about what you’re creating and how it’s created. By using mesh modeling you can transform a geometric virtual shape into a printed physical form—and this is just the beginning of what this technology can do. “If you understand 3D printing to mean the deposition and/or fusing of material by layer,” says Gil Akos, one half of design studio modeLab, “it really opens up what you could consider 3D printing to be. And then, shifting out of plastics into things like plant matter or even flesh—3D printing skin, things like that.” @stewart23rd
Design of the Week: Bone Chair This week’s selection is designer Joris Laarman’s Bone Chair, part of a seven-piece collection entitled, “Bone Furniture”. The chair is not directly 3D printed; rather it was cast in a single piece from a 3D printed ceramic mould. This is not a unique process, but we’re very interested in the design itself, inspired by the natural processes used by trees and animals: Trees have the ability to add material where strength it is needed, and bones have the ability to take away material where it is not needed. With this knowledge the International Development Centre Adam Opel GmbH, a part of General Motors Engineering Europe created a dynamic digital tool to copy these ways of constructing used for optimizing car parts. While it’s easy to look at directly produced 3D printed objects, there is a greater range of objects possible when using 3D printing technology for moulds, jigs and supports with other materials.
Military Researchers Develop Corpse-Eating Robots | Underwire Just as The Matrix ran off human batteries, new battlefield robots could jump-start themselves by eating human flesh. Image courtesy Warner Bros. From the file marked “Evidently, many scientists have never seen even one scary sci-fi movie”: The Defense Department is funding research into battlefield robots that power themselves by eating human corpses. What could possibly go wrong? Since they apparently don’t own TVs or DVD players, researchers at Robotic Technology say the robots will collect organic matter, which “could” include human corpses, to use for fuel. But if you picked up anything on flesh-eating robots over the years you know they’ll ignore that tasty soybean field and make a chow line right to the nearest dead body. Researchers seem to get a kick out of ensuring the demise of the human species, so the project is called the Energetically Autonomous Tactical Robot, or EATR. See also:
Le MoMA vient d'acquérir la première robe imprimée en 3D d'un seul coup Ce n’est évidemment pas la première robe imprimée en 3D et ce n’est pas, non plus, la première fois qu’on vous parle de robe imprimée en 3D – celle sur-mesure du studio SHIGO ou bien l’impressionnante x.pose ne sont que les dernières en date. Cependant il s’agit tout de même d’une premiere puisque le MoMA vient de faire rentrer dans sa collection la première robe intégralement imprimée en 3D, d’une seule traite, en un morceau, pas plusieurs petits assemblés par la suite. Cette pièce et la vidéo explicative qui l’accompagne sont l’oeuvre du studio new-yorkais Nervous System et ont été imprimé par Shapeways. La robe de plastique, étonnement légère, rejoint ainsi la collection des DIY “humble masterpieces” du fameux musée New-Yorkais. En plus d’être particulièrement élégante, bien qu’un peu dévêtue, cette robe est un ensemble de 2279 panneaux triangulaires aux comportements incroyablement complexe. Images via
Creating indestructible self-healing circuits Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the first time ever, has developed just such self-healing integrated chips. The team, made up of members of the High-Speed Integrated Circuits laboratory in Caltech's Division of Engineering and Applied Science, has demonstrated this self-healing capability in tiny power amplifiers. The amplifiers are so small, in fact, that 76 of the chips -- including everything they need to self-heal -- could fit on a single penny. "It was incredible the first time the system kicked in and healed itself. The team's results appear in the March issue of IEEE Transactions on Microwave Theory and Techniques.
The ‘World’s First’ 3D Printed Air Conditioner Sells in China for $6395 China has been at the forefront of 3D printing, taking the technology and utilizing it in ways that other countries around the world have been reluctant to do. Whether it is 3D printing houses, apartment buildings, or other large objects which some look at in amazement, while others just ask, “why”?, China certainly has been grabbing the attention of the international media when it comes to 3D printing intuitively designed products. So what could possibly be next for the world’s most populated country? How about a 3D printed, aesthetically designed, working air conditioning unit? While some may look at a 3D printed air conditioner and wonder what the point is, for one individual, the unit was worth spending a whopping 40,000 Chinese Yuan for. What makes the Haier 3D printed air conditioner so special is the fact that it can be completely customized to look and function exactly how its buyer wants it to. How’s that for a sales pitch?
First mind-reading implant gives rats telepathic power - life - 28 February 2013 Read full article Continue reading page |1|2 Video: Watch a pair of rats communicate by mind-reading The world's first brain-to-brain connection has given rats the power to communicate by thought alone. "Many people thought it could never happen," says Miguel Nicolelis at Duke University in Durham, North Carolina. The feat was achieved by first training rats to press one of two levers when an LED above that lever was lit. An array of microelectrodes – each about one-hundredth the width of a human hair – was then implanted in the encoder rats' primary motor cortex, an area of the brain that processes movement. Next, the team recreated these patterns in decoder rats, using an implant in the same brain area that stimulates neurons rather than recording from them. Implants linked The researchers then wired up the implants of an encoder and a decoder rat. The rats' ability to cooperate was reinforced by rewarding both rats if the communication resulted in a correct outcome. Wake-up call
How Team Obama’s tech efficiency left Romney IT in dust Despite running a campaign with about twice the money and twice the staff of Governor Mitt Romney's presidential bid, President Barack Obama's campaign under-spent Romney's on IT products and services by $14.5 million, putting the money instead into building an internal tech team. Based on an Ars analysis of Federal Election Commission filings, the Obama campaign, all-inclusive, spent $9.3 million on technology services and consulting and under $2 million on internal technology-related payroll. The bottom line is that the Obama campaign's emphasis on people over capital and use of open-source tools to develop and operate its sophisticated cloud-based infrastructure ended up actually saving the campaign money. As we revealed in our recent analysis of the Romney team's tech strategy, the Romney campaign spent $23.6 million on outside technology services—most of it on outside "digital media" consulting and data management.

On the Feasibility of Side-Channel Attacks with Brain-Computer Interfaces Brain computer interfaces (BCI) are becoming increasingly popular in the gaming and entertainment industries. Consumer-grade BCI devices are available for a few hundred dollars and are used in a variety of applications, such as video games, hands-free keyboards, or as an assistant in relaxation training. There are application stores similar to the ones used for smart phones, where application developers have access to an API to collect data from the BCI devices. The security risks involved in using consumer-grade BCI devices have never been studied and the impact of malicious software with access to the device is unexplored. We take a first step in studying the security implications of such devices and demonstrate that this upcoming technology could be turned against users to reveal their private and secret information. Papers are restricted to registered attendees until the event begins. Text of BibTeX entry:
Love Robot Holds Female Lab Intern Prisoner The robot Kenji at Toshiba's Akimu Robotic Research Institute was programmed by Dr. Akito Takahashi and his team to emulate certain human emotions, including love. However, Kenji began to display surprising behavior. The robot held a young female intern within its lab enclosure for a few hours, until she was freed by senior staff members. MuckFlash reports on Kenji in a posting titled, "Robot Programmed to Love Goes to Far." “Despite our initial enthusiasm, it has become clear that Kenji’s impulses and behavior are not entirely rational or genuine,” conceded Dr. Meet Nao: The first robot able to develop emotions and form a bond with humans By Daily Mail Reporter Updated: 11:52 GMT, 13 August 2010 The first robot capable of developing emotions and forming bonds with humans has been unveiled by scientists. Nao has been designed to mimic the emotional skills of a one-year-old child and is capable of forming bonds with people who treat it kindly. The robot has been developed to use the same types of expressive and behavioural cues that babies use to learn to interact socially and emotionally with others. It is able to detect human emotions by studying body-language and facial expressions and becomes better at reading someone's mood over time as it grows to 'know' the person. It is also able to remember its interactions with different people and memorise their faces. Nao have been created through modelling the early attachment process that human and chimpanzee infants undergo when they are very young. 'This behaviour is modelled on what a young child does,' said Dr Cañamero.
