What is graphene? Here’s what you need to know about a material that could be the next silicon. Graphene, an emerging material that could change the way electronic components are made and help computing performance continue to grow, is everywhere in the research world these days.
This month alone, advancements suggested it could boost internet speeds, serve as a touch sensitive coating and extend the lives of computers. It is stronger than diamond and conducts electricity and heat better than any material ever discovered, and it will likely play an important role in many products and processes in the future. What is graphene? Graphene is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons.
Graphene is one million times thinner than paper; so thin that it is actually considered two dimensional. Carbon is an incredibly versatile element. These single layers of carbon atoms provide the foundation for other important materials. How was it discovered? Chances are good that you have made graphene many times in your life. Why is it unusual? Technology and Education. Artificial Intelligence. FDA approves a life-like prosthetic arm from the man who invented the Segway. After years of testing, the FDA today approved a new type of prosthetic arm that its makers claim will bring a whole new level of control to amputees.
Known as the "Luke" arm or DEKA Arm System, Segway inventor Dean Kamen has been involved in its development and unlike existing prosthetics, it can understand multiple commands at once, giving its wearers "near-natural" control of the limb. As demonstrated in the videos embedded after the break, tests show wearers can get back to easily performing tasks like using keys and locks, brushing their hair, removing papers from an envelope, or picking up an egg without breaking it. While we've seen demos using other mind control techniques, the one approved for sale does its magic with electromyogram (EMG) sensors activated by the wearer contracting muscles close to where the prosthesis is attached or on their feet, which an embedded computer translates into movement.
Another triumph here is the (relative) speed of its approval. Comments. Why Apple vs. Google Is the Most Important Battle in Tech. In the 1990s, Microsoft Internet Explorer battled Netscape Navigator in the great Web-browser wars.
In the 2000s, Google and Yahoo locked horns over Internet search — and we know how that turned out. Today, the latest high-stakes tech conflict is between Apple’s iPhone and Google’s Android mobile operating system for supremacy in the smart-phone market. Each of these clashes defined an era of Internet history. Apple vs. Android is no different. Apple and Google realize how huge the stakes are in this fight. (MORE: Google Chairman Eric Schmidt Raps Apple on iPhone Maps, Floats Yahoo! This smart-phone showdown is important because Apple and Google are advancing radically different business models to the fight. Each company has been successful with its respective strategy: Apple makes $1 billion per month on iPhone sales, and the device is considered the gold standard for smart-phone design.

101 Most Useful Websites You Dont Know About. Education Week's Digital Directions: 'Second Life' Struggles to Catch On With Educators. Published Online: June 15, 2011 Published in Print: June 15, 2011, as Avatars Wanted Features During an informal “campﬁre chat” on the ISTE Second Life Island, participants discuss the themes from a series of virtual speaker presentations.
—Courtesy of ISTE Teachers from around the country are gathering together to visit the Alamo in San Antonio, the Holocaust Memorial Museum in Washington, and the Louvre in France in the span of a few hours without shelling out a dime. Those are the kinds of virtual experiences, made possible by a computer and a high-speed Internet connection, that first attracted educators to Second Life, technology experts say. Initially, there was a lot of excitement about the possibilities of using Second Life as a professional-development tool for educators. But, for a number of reasons, those expectations have largely fallen short, offering cautionary lessons about using technology for professional development.
