  • Intel’s Laser Chips Could Make Data Centers Run Better

    Silicon chips with optical technology allow a new form of superfast data connection.

    Intel hopes to make computing far more efficient by introducing a technology that replaces conventional copper data cables with faster optical data links. The breakthrough required Intel to fit lasers and other optical components onto silicon chips, which usually deal only with electronic signals.

  • NASA Moonshot Will Test Laser Communications

    NASA launches a moon satellite this week that will test ultrafast optical data transmission.

    A new communications technology slated for launch by NASA this Friday will provide a record-smashing 600 megabits-per-second downloads. The resulting probe will orbit the moon and send communications back to Earth via lasers.

  • We Need a Moore’s Law for Medicine

    Technology is the primary cause of our skyrocketing health-care costs. It could also be the cure.

    Moore’s Law predicts that every two years the cost of computing will fall by half. That is why we can be sure that tomorrow’s gadgets will be better, and cheaper, too. But in American hospitals and doctors’ offices, a very different law seems to hold sway: every 13 years, spending on U.S. health care doubles.

  • Leap Motion’s Struggles Reveal Problems with 3-D Interfaces

    It may take years for 3-D gesture-control to catch on with consumers and app developers.

    Hype surrounding Leap Motion, an $80 3-D gesture-control gadget touted for its exceptional finger-tracking accuracy, reached fever pitch in the weeks before its July launch. Hundreds of thousands of people ordered the device ahead of its release, and a flashy demo video on YouTube was viewed millions of times.

  • A Wearable Computer More Powerful than Glass, And Even More Awkward

    A startup that makes 3-D glasses stands out, in part, by including Steve Mann on its team.

    Steve Mann, a pioneer in the field of wearable computing, has been touting the benefits of head-mounted computers for decades. Now, the University of Toronto professor is also lending his weight and experience to a company hoping to loosen Google Glass’s grip on the nascent market with a different take on computer glasses that merges the real and the virtual.

  • Implanted Device Controls Rheumatoid Arthritis

    A nerve-stimulating electrical implant could give people a drug-free alternative to current treatments.

    In early human tests, SetPoint Medical has found that an electronic implant helped reduce the symptoms of rheumatoid arthritis in six of eight patients. The company, which is based in Valencia, California, is one of many groups exploring the potential of electronic implants to treat diseases by delivering pulses to nerves that regulate organ or body functions.

  • The Man Who Drew Up Sony’s Next Game Plan

    Mark Cerny’s journey from 17-year-old Atari programmer to lead architect of Sony Computer Entertainment will define the next blockbuster games console.

    Mark Cerny’s soft voice and youthful looks belie the position of power he holds in the video-game industry. The 49-year-old Californian is the lead architect of Sony’s PlayStation 4, the company’s forthcoming video-game console cum entertainment hub, which is destined to arrive in millions of living rooms around the globe this winter. As such he is partly responsible for defining the next generation of video-game consoles and shaping the broader influence of these increasingly pervasive devices. It is a unique challenge in technological design. Unlike PCs, smartphones, or televisions, new video-game consoles launch only intermittently, every seven years or so. The design must be robust enough to remain relevant in a rapidly shifting technological landscape over an extended period.
