    The newest AlphaGo mastered the game with no human input

    AlphaGo just leveled up.

    The latest version of the computer program, dubbed AlphaGo Zero, is the first to master Go, a notoriously complex Chinese board game, without human guidance. Its predecessor — dubbed AlphaGo Lee when it became the first computer program with artificial intelligence, or AI, to defeat a human world champion Go player (SN Online: 3/15/16) — had to study millions of...

    M. Ehsan Hoque develops digital helpers that teach social skills

    M. Ehsan Hoque, 35Computer scientistUniversity of Rochester

    A growing band of digital characters that converse, read faces and track body language is helping humans to communicate better with one another. While virtual helpers that perform practical tasks, such as dealing with customer service issues, are becoming ubiquitous, computer scientist M. Ehsan Hoque is at the forefront of a more...

    The incredible shrinking transistor just got smaller

    Carbon nanotubes may be the key to shrinking down transistors and squeezing more computer power into less space.

    Historically, the number of transistors that can be crammed onto a computer chip has doubled every two years or so, a trend known as Moore’s law. But that rule seems to be nearing its limit: Today's silicon transistors can’t get much smaller than they already are.

    Carbon...

    A quarter century ago, the qubit was born

    John Archibald Wheeler was fond of clever phrases.

    He made the term “black hole” famous in the 1960s. He also coined the now-familiar “wormhole” and “quantum foam.” While further pondering the mystery of quantum physics at the University of Texas at Austin during the 1980s, Wheeler repeatedly uttered his favorite interrogative slogan: “How come the quantum?” And from those ponderings...

    Quantum computers are about to get real

    Although the term “quantum computer” might suggest a miniature, sleek device, the latest incarnations are a far cry from anything available in the Apple Store. In a laboratory just 60 kilometers north of New York City, scientists are running a fledgling quantum computer through its paces — and the whole package looks like something that might be found in a dark corner of a basement. The...

    Choosing the right cyberattack response is a complicated game

    Many Americans were outraged over Russia’s e-mail hacking during the 2016 presidential election and expected a vigorous response from the U.S. government. But new research that views cyberattacks from a game theory perspective suggests that the delayed response was a sound one.

    While instinct suggests that such attacks deserve swift retaliation, viewing cyberwarfare through a...

    Winning against a computer isn’t in the cards for poker pros

    In the battle of wits between humans and machines, computers have just upped the ante.

    Two new poker-playing programs can best professionals at heads-up no-limit Texas Hold’em, a two-player version of poker without restrictions on the size of bets. It’s another in a growing list of complex games, including chess, checkers (SN: 7/21/07, p. 36) and Go (SN: 12/24/16, p. 28), in which...

  • Speech recognition has come a long way in 50 years

    Computers that hear

    Computer engineers have dreamed of a machine that would translate speech into something that a vacuum tube or transistor could understand. Now at last, some promising hardware is being developed.... It is still a long way from the kind of science fiction computer that can understand sentences or long speeches. — Science News, March 4, 1967

  • Germanium computer chips gain ground on silicon — again

    First germanium integrated circuits

    Integrated circuits made of germanium instead of silicon have been reported … by researchers at International Business Machines Corp. Even though the experimental devices are about three times as large as the smallest silicon circuits, they reportedly offer faster overall switching speed. Germanium … has inherently greater mobility than silicon, which...

    Retracted result on network equivalence reinstated

    A computer scientist has taken his colleagues on a rollercoaster ride.

    In the span of several days, László Babai of the University of Chicago walked back his earlier claim of making a major advance on a classic puzzle of computer science, only to reinstate it after fixing an error in his work.

    At issue is the problem of “graph isomorphism,” which demands that a computer determine...
