Stanford creates touch-sensitive, conductive, infinitely-self-healing synthetic skin Stanford University material scientists have devised the first synthetic, plastic skin that is conductive, sensitive to touch, and capable of repeatedly self-healing at room temperature. The most immediate applications are in the realm of smart, self-healing prosthetic limbs that are covered in this synthetic skin — but in the long term, the plastic might be used to make self-healing electronic devices, or you might even elect to replace your fingertips (or other piece of skin) with the synthetic, bionic equivalent. There are two important innovations here: a synthetic material that can repeatedly self-heal, and the fact that it’s electrically conductive — meaning it can detect changes in pressure and temperature (i.e. it’s sensitive, like real skin). We’ll tackle the self-healing bit first. The Stanford team, led by Zhenan Bao, started with plastic polymer that’s held together with hydrogen bonds.

How the “internet of things” will replace the web The second in a series. We’ve already written about why 2014 is really, finally the year that the “internet of things”—that effort to remotely control every object on earth—becomes visible in our everyday lives. But most of us don’t recognize just how far the internet of things will go, from souped-up gadgets that track our every move to a world that predicts our actions and emotions. In this way, the internet of things will become more central to society than the internet as we know it today. The web will survive, just as email survived the arrival of the web. But its role will be reduced to that of a language for displaying content on screens, which are likely to be more ubiquitous but less necessary.
How Car Engines Work" Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated. You might want to know what's going on simply out of curiosity. Or perhaps you are buying a new car, and you hear things like "3.0 liter V-6" and "dual overhead cams" and "tuned port fuel injection." What does all of that mean? First inkjet-printed graphene computer circuit is transparent, flexible You can add another crazy characteristic to graphene’s ever-expanding list of “wonder material” properties: It can now be used to create flexible, transparent thin-film transistors… using an inkjet printer. The discovery comes from researchers at the University of Cambridge, UK, who were trying to ameliorate the lackluster performance of existing inkjet-printed electronics. As we covered last month, it’s possible to print standard CMOS transistors using different ferroelectric polymer inks, but the resultant circuit is so slow that it can’t actually function as a computer. If graphene could replace or augment the interconnects or transistors, these circuits would be a lot faster — and that’s what these Cambridge engineers have done. The actual meat of the discovery is that graphene has been successfully chipped off a block of graphite using a chemical solvent. These flakes are then filtered to remove any larger, print head-clogging chunks, and then turned into a polymer ink.
First Bulgarian laptop: the Pravetz legend braces for a comeback - Economy After 30 years, a legend braces for a comeback. In this way the ambitious Bulgarian engineers behind the restart the Bulgarian computer brand Pravetz made during communism, have announced their plans to manufacture a laptop under the famous brand. The news has become vastly popular online and has sparked off a discussion about the revival of the Bulgarian Silicon Valley. In fact, the news about the soon-to-be released Bulgarian laptop with the name Pravetz 64 M has come as a shock to many Bulgarians. Some have thought it could be a kind of joke.

The first 3D-printed human stem cells The shortage of transplantable organs has spawned a fascinating science and market. A liver, for example, is often split among two recipients, while for a cystic fibrosis patient in need of two lungs, it is technically preferable to just swap out both the heart and lungs as a combo unit. The extra heart can then be domino donated to a third party. Bioprinting complete organs en masse is a tough proposition because the identity expressed by each component cell must be individually programmed.
3D printing with metal: The final frontier of additive manufacturing The holidays are a great time to sit back, relax, and watch the world happen around you. Few areas of technology have seen as much development in one year as that of 3D printing. Undoubtedly, the most dramatic and challenging has been printing with metal. Bill Lear William Powell (Bill) Lear (June 26, 1902 – May 14, 1978) was an American inventor and businessman. He is best known for founding the Lear Jet Corporation, a manufacturer of business jets. He also invented the B-battery eliminator and developed the 8-track cartridge, an audio tape system which was widely used in the 1960s and 1970s. Early life 6 free mobile device emulators for testing your site The percentage of all web usage that comes from smartphones and other mobile devices is growing, and it won’t be long before mobile internet users overtake desktop and laptop users in terms of web traffic. So it’s a cardinal sin to ignore mobile users when you’re developing a website. One of the most important things you can do to make a website mobile-friendly is to test it on multiple smartphone and tablet platforms.
