Stephen Hawking: ‘Transcendence looks at the implications of artificial intelligence – but are we taking AI seriously enough?’

May 4, 2014 / / 0 Comments

With the Hollywood blockbuster Transcendence playing in cinemas, with Johnny Depp and Morgan Freeman showcasing clashing visions for the future of humanity, it’s tempting to dismiss the notion of highly intelligent machines as mere science fiction. But this would be a mistake, and potentially our worst mistake in history. Artificial-intelligence (AI) research is now progressing rapidly. Recent landmarks such as self-driving cars, a computer winning at Jeopardy! and the digital personal assistants Siri, Google Now and Cortana are merely symptoms of an IT arms race fuelled by unprecedented investments and building on an increasingly mature theoretical foundation. Such achievements will probably pale against what the coming decades will bring.The potential benefits are huge; everything that civilisation has to offer is a product of human…

The Hackers Who Recovered NASA’s Lost Lunar Photos, Wired “Sitting incongruously among the hangars and laboratories of NASA’s Ames Research Center in Silicon Valley is the squat facade of an old McDonald’s. You won’t get a burger there, though-its cash registers and soft-serve machines have given way to old tape drives and modern computers run by a rogue team of hacker engineers who’ve rechristened the place McMoon’s. These self-described techno-archaeologists have been on a mission to recover and digitize forgotten photos taken in the ’60s by a quintet of scuttled lunar satellites. The Lunar Orbiter Image Recovery Progject has since 2007 brought some 2,000 pictures back from 1,500 analog data tapes. They contain the first high-resolution photographs ever taken from behind the lunar horizon…

Arecibo Observatory Detects Mysterious, Energetic Radio Burst

April 21, 2014 / / 0 Comments

A brief, blazing burst of radio waves detected by the Arecibo Observatory could herald a turning of the tide for a peculiar class of cosmic signals. Until recently, the signals had only ever been detected by a telescope in Australia, a pattern that fueled doubts about their origin. Fewer than a dozen of these bursts, lasting for only a few thousandths of a second, have ever been reported. Called fast radio bursts, the signals are cosmic enigmas that appear to come from the very, very distant universe. But since the first burst discovery in 2007, scientists have not only wondered what kind of cosmic object could produce such a tremendously bright, short-lived radio pulse but have disagreed about whether the bursts are even celestial. …
