    The unmanageable in-box, the cellphone and laptop that keep you electronically tethered to the office, the endless 30-second distractions from incoming e-mail and text messages. Sound familiar? The same advances in computers and telecommunications that have brought about tremendous gains in productivity have also made the work lives of professionals a misery. No wonder that these days many people's dream vacations include thoughts of tossing their mobile phones into a mountain stream and fully unplugging. View full abstract»

  • Finding the source of the pioneer anomaly

    Some 40 years ago, a quarter-ton lump of circuits and sensors slipped Earth's surly bonds, sped past the moon and Mars, and hurtled toward Jupiter. The probe, Pioneer 10, and its sister ship, Pioneer 11, which followed a year later, were true trail blazers . They gave humanity its first close-up glimpses of worlds beyond the solar system's asteroid belt. They also left behind a mystery-one that has simultaneously baffled and inspired as trophysicists for years. View full abstract»

    Raising money to fund product development is never easy, as any tech entrepreneur will tell you. But I've had to grapple with a unique complication: My company, WindLift, is developing a kite-based system that generates electricity. The prototype, designed to put out 12 kilowatts, could save tons of money for some people now using diesel generators. But when I pitch the business to potential investors, it often seems as if all they can remember is their childhood struggles with those cheap stick-and-string fliers, making it impossible for them to envisage what my company aims to achieve.

  • The broadcast empire strikes back

    It's an increasingly urgent question. After all, thousands of broadcast stations worldwide collectively own the rights to vast and immensely valuable swaths of radio spectrum. As demand for mobile data skyrockets and interest in broadcast television merely plateaus, telecom companies have been arguing that they can put that spectrum to better use. They have been pressuring government regulators for years to reclaim some broadcast channels and auction off the corresponding spectrum. View full abstract»
