A ‘shockingly bright’ gamma-ray burst

May 7, 2013

Swift's X-Ray Telescope took this 0.1-second exposure of GRB 130427A at 3:50 a.m. EDT on April 27, just moments after Swift and Fermi triggered on the outburst. The image is 6.5 arcminutes across. (Credit: NASA/Swift/Stefan Immler)

A record-setting blast of gamma rays from a dying star in a galaxy about 3.6 billion light-years away has wowed astronomers around the world — the highest-energy light ever detected from such an event.

At 3:47 a.m. EDT, April 27, Fermi’s Gamma-ray Burst Monitor (GBM) triggered on an eruption, designated GRB 130427A, of high-energy light in the constellation Leo.

The Fermi Large Area Telescope (LAT) recorded one gamma ray… read more

A.I. expert Ray Kurzweil picks computer in ‘Jeopardy!’ match

February 9, 2011

Watson has the inside track on the “Jeopardy!” contest Monday Feb. 14, when the IBM computer system called “Watson” faces off against past “Jeopardy!” champs, says Ray Kurzweil. “But if it doesn’t win, it will come close, and it will come back and win in the very near future. Because it’s only going to get better. And humans are not getting better.”

Based on his calculations of the… read more

A.I. Reboots

February 21, 2002

The focus of artificial intelligence today is no longer on understanding and replicating human intelligence but the development of systems to augment human abilities.
Promising applications of the “new A.I.” include:

  • CycSecure, a program to be released this year that combines a huge database on computer network vulnerabilities with assumptions about hacker activities to identify security flaws in a customer’s network.
  • The “Semantic Web,” a sophisticated

    A.I.: Unraveling the Mysteries

    June 28, 2001

    Kubrick diehards have been playing an educated guessing game about A.I. … And in recent months, a younger, more Web-savvy set has been engaged in an elaborate interactive game that’s actually a marketing effort for the movie ….

    AAA Battery Gets a Mini-Me

    October 9, 2003

    The smallest implantable battery in the world may soon be powering bionic neurons. The small size allows doctors to use minimally invasive techniques when implanting the bionic neurons, reducing surgical trauma and the risk of infection.

    Recharging is done wirelessly by an external electrical field, so implants no longer have to be surgically removed and replaced.

    The battery may power implantables for stroke victims and people suffering from… read more

    Aaron: AI-based painter program

    May 12, 2001

    Aaron, an AI-based program that creates original paintings on your computer’s screen, has passed the art world’s Turing Test, says its creator, Harold Cohen, artist and University of California at San Diego art professor.

    “Aaron’s output has been hung in major museums all around the world,” he said. “Since most of that happened before anybody was aware of how powerful the computer was, I have to assume… read more

    ABB’s FRIDA offers glimpse of future factory robots

    This headless, two-armed robot may be tomorrow’s factory worker.

    Its name is FRIDA (Friendly Robot for Industrial Dual-arm Assembly), and it’s a creation of ABB, the Swiss power and automation giant, which introduced it early this month at the Hannover trade show, Europe’s largest industrial fair.

    Designed for assembly applications, FRIDA is capable of using its human-like arms to grasp and manipulate electronic components and other small parts.… read more

    ABC’s FlashForward Goes Crazy With Online Content

    ABC TV’s new FlashForward drama/mystery series could be one of the first major network dramas to understand the potential of social media.

    Abdominal fat hormone promotes more abdominal fat

    April 21, 2008

    University of Western Ontario researchers have found that abdominal fat makes a hormone that both stimulates hunger and increases the number of fat cells, in a potentially vicious cycle.

    It was previously thought that only the brain made Neuropeptide Y (NPY), the most potent appetite-stimulating hormone known, but in obese rats, NPY was produced locally by abdominal fat. NPY stimulates the replication of fat cell precursor cells, which then… read more

    Ability to ‘think about thinking’ not limited to humans

    Another distinction between "humans" and "animals" removed

    Humans’ closest animal relatives, chimpanzees, have metacognition — knowing what one knows, according to new research by scientists at Georgia State University and the University at Buffalo.

    “The demonstration of metacognition in nonhuman primates has important implications regarding the emergence of self-reflective mind during humans’ cognitive evolution,” the research team noted.

    Metacognition is the ability to recognize one’s own cognitive states. For example, a game show… read more

    About Those Fearsome Black Holes? Never Mind

    July 22, 2004

    Stephen Hawking declared at a scientific conference in Dublin that he had been wrong in a controversial assertion he made 30 years ago about black holes.

    He had said information about what had been swallowed by a black hole could never be retrieved from it. This would have been a violation of quantum theory, which says that information is preserved.

    Accelerated electrons enable ‘extraordinarily strong’ negative refraction

    May lead to ultra-powerful microscopes and ability to grab viruses and even individual molecules

    Researchers at the Harvard School of Engineering and Applied Sciences (SEAS), collaborating with the Weizmann Institute of Science in Israel, have demonstrated a new way of achieving negative refraction in a metamaterial — as large as -700, more than a 100 times larger than most previously reported.

    “This work may bring the science and technology of negative refraction into an astoundingly miniaturized scale, confining the negatively… read more

    Accelerated Living

    September 7, 2001

    “Imagine a Web, circa 2030, that will offer a panoply of virtual environments incorporating all of our senses, and in which there will be no clear distinction between real and simulated people.” That’s part of Ray Kurzweil’s imaginative view of the future in PC Magazine’s special “20th Anniversary of PCs” issue.
    Among Kurzweil’s other forecasts for the next 30 years:

    Accelerating Change

    August 14, 2003

    The defining political conflict of the 21st century is shaping up to be the battle over the future of technology. Fortunately, technological progress doesn’t just have opponents; it also has boosters.

    The rise of neo-Luddism is calling forth self-conscious defenders of technological progress. Growing numbers of extropians, transhumanists, futurists and others are entering the intellectual fray to do battle against the neo-Luddite activists who oppose biotechnology, nanotechnology, and new… read more
