Intel powers more TOP500 supercomputers

June 24, 2003

The number of Intel systems in the on the just-published 2003 Top500 supercomputer list more than doubled in the last six months from 56 to 119.

NEC’s Earth Simulator supercomputer is still number 1, with 35.86 Tflop/s, followed by HP’s ASCI Q system at Los Alamos National Laboratory, with 13.88 Tflop/s. But the Intel Xeon-based MCR cluster at Lawrence Livermore National Laboratory moved up to number 3.… read more

Driver-less car in high-speed rally assault

November 2, 2009

Stanford engineers are developing the first autonomous racing car to climb Pikes Peak, a challenging 12.4-mile ascent in the Rocky Mountains, at 130 mph, as a way to create and test safety systems they hope one day will be used in all vehicles.

Rescue robots compete to save dolls in distress

April 22, 2008

Robots in this year’s RoboCup Rescue competition in China this July must navigate a complex three-dimensional maze, using their sensing and mapping abilities to sniff out toy dolls that either emit CO2, give off heat, make noise, or move.

The competition aims to stimulate development of robots to help humans in dangerous situations, like collapsed buildings or after a chemical spill.

The competition will include a “manipulation challenge”… read more

Now the bionic man is real …

April 17, 2006

The 1970s gave us the six-million-dollar man. Thirty years and quite a bit of inflation later we have the six-billion-dollar human: not a physical cyborg as such, instead an umbrella term for the latest developments in the growing field of technology for human enhancement.

Unexpected adhesion properties of graphene may lead to new nanotechnology devices

August 29, 2011

This is an artist's rendering of an array of pressurized graphene membranes. A CU-Boulder team recently discovered that graphene has surprisingly high adhesion properties, findings that may help lead to the development of new graphene-based mechanical devices like gas separation membranes (credit: Illustration courtesy Victor Tzen and Rex Tzen)

Graphene has surprisingly powerful adhesion qualities that could make possible graphene-based mechanical devices such as gas separation membranes, researchers at the University of Colorado Boulder have found.

The team measured the adhesion energy of graphene sheets, ranging from one to five atomic layers, with a glass substrate, using a pressurized “blister test” to quantify the adhesion between graphene and glass plates. The… read more

Website turns tables on government officials

July 6, 2003

MIT researchers have created the Government Information Awareness (GIA) project as a response to the US government’s Total Information Awareness program.

Internet users can submit their own intelligence reports on government officials; they will be published with no effort to verify their accuracy. Software similar to Google also gleans information from Internet sites that store information about politicians. Users can also access information compiled from various real-time… read more

Live high-res video feeds by cell phones now possible

November 10, 2009

Mobile video broadcasting service Qik plans to announce today the first high-resolution mobile streaming service, with beta support of the new Droid cellphone handset’s 720×480 (DVD-quality) video resolution, MobileCruch reports.

The combination allows for high-quality personal narrowcasting to family, friends, social networks, and live feeds by individuals to TV networks for breaking news or remote coverage of disasters and other events.

More-Accurate Radiation Therapy

April 24, 2008

Engineers at Purdue University are developing a simple wireless device that when implanted into tumors could give clinicians a more accurate indication of the amount of radiation that the tumors receive during treatment.

Subliminal advertising may work after all

May 1, 2006

Researchers have shown that if the conditions are right, subliminal advertising to promote a brand can be made to work.

Google co-founder Sergey Brin is among the inventors listed on a patent issued this week for “Seeing With Your Hand”: a glove with sensors for viewing a room.

Why A.I. Is Brain-Dead

July 16, 2003

“There is no computer that has common sense,” says Marvin Minsky. “We’re only getting the kinds of things that are capable of making an airline reservation. No computer can look around a room and tell you about it.”

AI’s biggest deficiency right now: “The lack of people with an interest in commonsense reasoning for computers…it’s hard to get 10 capable people.”

Asked to “Pick one: Bill Joy or… read more

Tiny Particles Can Deliver Antioxidant Enzyme to Injured Heart Cells

November 16, 2009

Georgia Tech scientists have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart, reducing the number of dying cells and resulting in improved heart function in rats.

The enzyme in the particles, called superoxide dismutase (SOD), soaks up toxic free radicals produced when cells are deprived of blood during a heart attack.

Death of the sitcom frees up 2,000 Wikipedias worth of cognitive capacity

April 28, 2008

In Here Comes Everybody, Clay Shirky proposes the idea of “cognitive surplus” — that automation gave us an enormous amount of free time to think and cogitate, and that sitcoms and other light entertainment from the past century were a way of absorbing that surplus, something we’re just shaking off now.

In a talk, he compared Wikipedia, which represents the cumulation of about 100 million hours of human thought,… read more

FDA Asked to Better Regulate Nanotechnology

May 18, 2006

A coalition of consumer and environmental groups petitioned the Food and Drug Administration to beef up its regulation of nanoparticle-containing sunscreens and cosmetics and recall some products.

Ferroelectrics may lead to ultra-low-power computing

September 13, 2011

Negative Capacitance

Engineers at the University of California, Berkeley, have shown that it is possible to reduce the minimum voltage necessary to store charge in a capacitor, an achievement that could reduce the power draw and heat generation of today’s electronics.

“Just like a Formula One car, the faster you run your computer, the hotter it gets. So the key to having a fast microprocessor is to… read more
