Pentagon’s ‘wish list’ to enhance commandos’ abilities

February 18, 2003

DARPA is seeking digital analysis and artificial intelligence technology that may enable analysts to track terrorists’ financial transactions and communications.

Robotics put new face on the future

February 17, 2003

Robots could be based on adaptive animals like octopi and could use new electroactive polymers that emulate muscle tissue. These could lead to more realistic and capable robots.

The scientists spoke at a symposium on “biologically inspired intelligent robots” at the annual meeting of the American Association for the Advancement of Science.

New robot face smiles and sneers

February 17, 2003

The new K-bot robot can express a full repertoire of human facial expressions and could be a useful tool for scientists researching AI.

She has 28 facial movements, including smiling, sneering, furrowing her brow and arching her eyebrows. She also has cameras in her eyes to recognize and respond to humans.

K-bot is the creation of David Hanson, a former Disney employee now working at the University of… read more

Our Bodies, Our Fears

February 16, 2003

Americans say they’re more anxious than ever. Scientific research about how our brains and bodies process fear can teach us how to live with long-term stress.

Artificial worlds used to unlock secrets of human interaction

February 16, 2003

Agent-based modeling is a new tool to look for elementary principles of self-organization that might shed new light on long-standing puzzles about how humans interact, according to sociologist Michael Macy of Cornell University, speaking at the Feb. 14 at the annual meeting of the American Association for the Advancement of Science.

Biology to make mini machines

February 16, 2003

Computers of the future will be built not by factory machines, but by living cells such as bacteria.

Long distance quantum teleportation draws closer

February 13, 2003

Researchers in Austria have solved a problem plaguing long distance quantum teleportation: verifying that information has been transmitted has required the quantum link itself to be destroyed, preventing any further use.

The solution was to reduce the intensity of the source used to fire photons at the entangled pair, lowering the total number of photons in the system and hence also the number of false positives. Now, if the… read more

Discovering a Secret of Long Life

February 13, 2003

Scientists at the California Institute of Technology have discoverd a common mitochrondrial DNA genetic mutation in people who live longer than 100 years. The finding could help advance ways to counteract the ravages of aging.

NEC image processor runs 50.2 giga-operations per second

February 11, 2003

NEC Corp. has developed a single-chip parallel processor dedicated to image recognition that processes 50.2 giga-operations per second, about four times faster than a 3-GHz processor for PCs, but consumes about one tenth as much power.

Supercomputing Resurrected

February 11, 2003

Last year, Japan fired up an ultrafast computer that puts its closest competitors to shame. What will it take for the United States to catch up?

CONSCIOUSNESS AND THE BRAIN

February 11, 2003

Nobel laureate Francis Crick and and neuroscientist Christof Koch outline a strategy to develop a coherent scheme for determining the neural correlates of consciousness in philosophical, psychological and neural terms in the February issue of Nature Neuroscience.

Their approach centers on the visual system of primates, drawing on data from electrical recordings in awake monkeys, behavioral studies in humans and the effects of specific brain damage. Much of the… read more

Intel unveils ‘building blocks’ for 10-GHz processors

February 11, 2003

Intel Corp. plans to disclose this week several technologies that will make good on its promise to deliver 10-GHz or faster microprocessors by the end of this decade. The company is also expected to develop and ship processors that run at speeds from 10 to 20 GHz by then.

A Glimpse of a Future in a New Kind of Light

February 11, 2003

Lighting experts expect the pace of change in developing light-emitting diodes to pick up as researchers shrink the chips to microscopic size, improve their already impressive energy efficiency and increase their brightness. The chips are expected to move into the general home and office lighting market as early as 2007.

The eventual result, the experts say, will be savings of billions of dollars annually in energy and maintenance costs… read more

Saving the universe

February 11, 2003

NASA is expected to announce this week that it has proved the existence of “dark energy,” a cosmic force that counteracts gravity and will keep the universe expanding forever. The announcement will effectively demolish the theory that life will be wiped out in a “big crunch” when the universe collapses, and should end decades of academic dispute.

NASA has found a pattern of “hot spots” which proves that the… read more

How Vulnerable Is the Internet Now?

February 11, 2003

According to Gartner research director Richard Stiennon, it would not be difficult for an attacker to send spoofed routing tables to poorly configured routers and misdirect traffic across large parts of the Internet. Such an incident would be hard to fix.
