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...
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...
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, 1967Update
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,...
News in Brief
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...
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...
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...
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...

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...
