    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...

    Hidden Figures highlights three black women who were vital to the U.S. space program

    View trailer

    Hollywood space flicks typically feature one type of hero: astronauts who defy the odds to soar into space and back again. But now a group of behind-the-scenes heroes from the early days of the U.S. space program are getting their due. Black female mathematicians performed essential calculations to safely send astronauts to and from Earth’s surface — in defiance of flagrant...

    Year in review: AlphaGo scores a win for artificial intelligence

    In a hotel ballroom in Seoul, South Korea, early in 2016, a centuries-old strategy game offered a glimpse into the fantastic future of computing.

    The computer program AlphaGo bested a world champion player at the Chinese board game Go, four games to one (SN Online: 3/15/16). The victory shocked Go players and computer gurus alike. “It happened much faster than people expected,” says...

    AI system learns like a human, stores info like a computer

    A GPS app can plan the best route between two subway stops if it has been specifically programmed for the task. But a new artificial intelligence system can figure out how to do so on the fly by learning general rules from specific examples, researchers report October 12 in Nature.

    Artificial neural networks, computer programs that mimic the human brain, are great at learning patterns...

    Digital rehab exposes Biblical roots of ancient Israeli scroll

    Researchers have digitally unwrapped and read an ancient Hebrew scroll that’s so charred it can’t be touched without falling apart. It turns out the document contains the oldest known Biblical text outside of the roughly 2,000-year-old Dead Sea Scrolls, the investigators say.

    Archaeologists discovered the scroll’s remnants in a synagogue’s holy ark during a 1970 excavation in Israel of...

    Jeremy Freeman seeks to simplify complex brain science

    Jeremy Freeman, 30NeuroscientistHoward Hughes Medical Institute, Janelia Research Campus

    Jeremy Freeman loves clean, simple lines. To see his bent toward aesthetic minimalism, you need look no further than his spare, calm website that slowly shifts colors.

    In the past, this fixation with style has occasionally veered toward the extreme. In graduate school at New York University, “...

    Shayan Oveis Gharan finds the shortest route to success

    Shayan Oveis Gharan, 30Theoretical computer scientistUniversity of Washington

    It’s a problem that sounds simple, but the best minds in mathematics have puzzled over it for generations: A salesman wants to hawk his wares in several cities and return home when he’s done. If he’s only visiting a handful of places, it’s easy for him to schedule his visits to create the shortest round-trip...

    What Donkey Kong can tell us about how to study the brain

    Brain scientists Eric Jonas and Konrad Kording had grown skeptical. They weren’t convinced that the sophisticated, big data experiments of neuroscience were actually accomplishing anything. So they devised a devilish experiment.

    Instead of studying the brain of a person, or a mouse, or even a lowly worm, the two used advanced neuroscience methods to scrutinize the inner workings of...

    Supersmall device uses individual atoms to store data

    These orderly patterns of dark blue dots indicate where individual chlorine atoms are missing from an otherwise regular grid of atoms. Scientists manipulated these vacancies to create a supersmall data storage device.

    The locations of vacancies encode bits of information in the device, which Sander Otte of Delft University of Technology in the Netherlands and colleagues describe July 18...
