At the Computer Human Interaction conference in B.C. this week, a team from Texas A&M University unveiled a touch screen technology they've been incubating for a couple of years that isn't really a screen at all. ZeroTouch, as the project is known, is more like an empty picture frame lined with LEDs and filled with criss-crossing beams of infrared light.
There are few better ways to learn about how computers work than by building one from scratch, and few better excuses to snap fresh, solder-scented boards into waiting ports, if you're one to enjoy such things. But if you're primarily a Mac user like me, the call of that great geek rite of passage may have as yet gone unanswered; homebuilt PCs can't run OS X natively.
But listen here, Mac geeks. Thanks to the efforts of an increasingly active online community of developers, building a Hackintosh--a PC built from components that runs OS X like a charm--has never been easier. And by choosing your own hardware, it's entirely feasible to rival the specs of a brand-new Mac Pro for around half the cost.
This week, over the course of three articles, I'm going to show you exactly how easy building and configuring your own Hackintosh can be.
Researchers testing mental illness figured out how to induce schizophrenic symptoms in a computer, causing it to place itself at the center of crazy delusions, such as claiming responsibility for a terrorist bombing. The results bolster a hypothesis that claims faulty information processing can lead to schizophrenic symptoms.
In a move that could remake the microchip industry, Intel announced Wednesday it will start mass-producing the first three-dimensional silicon transistors. The 3-D transistor design, which Intel says will improve efficiency by more than one-third, will be integrated into a 22-nanometer node in an Intel chip called Ivy Bridge.
Finally, someone has reached fiber optic speeds so fast we can’t even think of how they could possibly be useful. Two separate research teams using different methods have topped the 100 terabits per second mark through a single optical fiber. That’s enough data flow to download three seamless months worth of HD video in a single second.
The rapid pace of innovation and the relentless pressure of Moore’s Law means new and better gadgets are always coming to market, but it also means whatever you just bought for several hundred (or thousand) dollars will likely be obsolete in a matter of months (see: the iPhone through the iPhone 4). But a new kind of shape-shifting chip--if it can be tamed and perfected--could change all that, allowing device hardware to be reconfigured when updated designs become available.
In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new teleportation breakthrough is a major step toward building safe, effective quantum computers.

New integrated circuits use photons to build fast and extremely power-efficient supercomputers
By Valerie RossPosted 03.24.2011 at 11:00 am 12 Comments
The speed of light is as fast as it gets, and IBM researchers are exploiting that fact to give supercomputers a boost. They've made the smallest-yet silicon chips that use light to transmit information.
