University of Edinburgh researchers used low-energy lasers to make salt crystals in gel, which could make it possible to store a terabyte of data in a space the size of a sugar cube within the next 10 years. The researchers focused two overlapping low-energy laser beams on a salt solution, which provided the exact right amount of energy to form a temporary crystal. Edinburgh professor Andy Alexander says the process could be used to improve on traditional methods of optical data storage such as CDs. In comparison to the two-dimensional surface of a CD, three-dimensional (3D) optical data storage contains far more layers, and tiny crystals could act as storage points. Information would be stored by making marks in a pattern and read using light. Alexander says that 3D, crystal-based devices could be available within 10 years and would enable users to easily store, access, and move massive amounts of data. “This research builds on a discovery that was made by accident many years ago, when it was found that light can be used to trigger crystal formation,” he says. “We have refined this technique and now we can create crystals on demand. There is much work to be done before these crystals can be used in practical applications such as optical storage, but we believe they have significant potential.”

The U.S. Federal Communications Commission (FCC) unanimously voted to start drafting rules to support Internet neutrality. “It’s hard to imagine anything more important to the future of the success of our economy than a healthy and vibrant Internet, and there is no question that the openness of the Internet is the secret sauce to its success,” said FCC chairman Julius Genachowski following the vote. He also noted that the FCC has a core agenda to drive investment, innovation, and opportunity in 21st century communications. In addition to providing their customers with consistent Web traffic, Internet service providers (ISPs) would need to detail their network traffic management operations to ensure no wrongdoing. The U.S. government’s previous stance on the Web regulation issue was one of non-involvement, but it changed its position as worries mounted that ISPs could begin to exhibit favoritism toward their products and services. Crafting the rules will be a long, contentious process as wireless carriers, telecommunications firms, and other industry players and participants sound off on the benefits and drawbacks. The FCC’s Democratic commissioners are vocal advocates of net neutrality rules, while the agency’s Republican commissioners argue that such regulations are unnecessary. Critics are concerned that Web regulation will have an adverse effect on innovation in the Internet sector. However, Genachowski disagrees that the rules would hamper investment in broadband networks. “I reject the notion that we must choose between open Internet rules and investment by service providers in their networks,” he said during the meeting.
