  • On the Horns of the GMO Dilemma

    Can genome-editing technology revive the idea of genetically modified livestock?

    Four years ago, Scott Fahrenkrug saw an ABC News segment about the dehorning of dairy cows, a painful procedure that makes the animals safer to handle. The shaky undercover video showed a black-and-white Holstein heifer moaning and bucking as a farmhand burned off its horns with a hot iron.

  • The Man Who Really Built Bitcoin

    Who cares about Satoshi Nakamoto? Someone else has made Bitcoin what it is and has the most power over its destiny.

    In March, a bewildered retired man faced journalists yelling questions about virtual currency outside his suburban home in Temple City, California. Dorian Nakamoto, 64, had been identified by Newsweek as the person who masterminded Bitcoin—a story that, like previous attempts to unmask its pseudonymous inventor, Satoshi Nakamoto, was soon discredited. Meanwhile, the person arguably most responsible for enabling the currency to swell in value to $7.7 billion, and with the most influence on its future, was hiding in plain sight on the other side of the country, in Amherst, Massachusetts.

  • A Chinese Internet Giant Starts to Dream

    Baidu is a fixture of online life in China, but it wants to become a global power. Can one of the world’s leading artificial- intelligence researchers help it challenge Silicon Valley’s biggest companies?

    Punk bands from Blondie to the Ramones once played in Broadway Studios, an age-worn 95-year-old neoclassical building surrounded by strip clubs in San Francisco’s North Beach. But early on this bright June morning, a different sort of rock star arrives. A small crowd attending a tech startup conference swarms around a tall, soft-spoken man in a blue dress shirt and navy suit who politely poses for photos. Andrew Ng, newly appointed chief scientist at Baidu, China’s dominant search company, is here to talk about his plans to advance deep learning, a powerful new approach to artificial intelligence loosely modeled on the way the brain works. It has already made computers vastly better at recognizing speech, translating languages, and identifying images—and Ng’s work at Google and Stanford University, where he was a professor of computer science, is behind some of the biggest breakthroughs. After his talk, the audience of about 200 entrepreneurs, venture capitalists, and tech workers sends him off with two rounds of applause.

  • Bendable Displays Are Finally Headed to Market

    Flexible displays haven’t been usable as touch screens, or durable—those problems have now been solved.

    By the end of this year, a startup called Kateeva will start shipping manufacturing equipment that could finally bring flexible displays to market.

  • Turning a Regular Smartphone Camera into a 3-D One

    Microsoft researchers say simple hardware changes and machine learning techniques let a regular smartphone camera act as a depth sensor.

    Just about everybody carries a camera nowadays by virtue of owning a cell phone, but few of these devices capture the three-dimensional contours of objects like a depth camera can.
