China to be biggest chip market by 2008, says ST

November 16, 2004

By 2008 the market for semiconductors in China will be the largest in the world at about $50 billion, aocording to STMicroelectronics estimates.

The eastern part of the globe will represent 66 percent of the market for semiconductors and the western part, Europe and the Americas, just 34 percent.

Drawing nanoscale features the fast and easy way

September 11, 2007

Scientists at the Georgia Institute of Technology have developed a new technique for nanolithography that is extremely fast and capable of being used in a range of environments including air and liquids.

The technique, known as thermochemical nanolithography, may allow industry to produce a variety of nanopatterned structures, including nanocircuits, at a speed and scale that could make their manufacture commercially viable. Using an atomic force microscope (AFM), researchers… read more

Chameleon-nanostructure sensors developed

April 23, 2001

Intelligent nanostructures that report on their environment by changing color from blue to fluorescent red under mechanical, chemical, or thermal stress have been created by researchers at Sandia National Laboratories and the University of New Mexico.

The self-assembling structures, reported in the April 19 Nature, may lower costs by reducing the need for expensive manufactured devices like stress detectors, chemical analyzers, and thermometers, according the Sandia researchers.

Road Map for Financial Recovery: Radical Transparency Now!

February 24, 2009

“We need to rethink our entire philosophy of regulation,” says Wired writer David Roth. “Instead of assigning oversight responsibility to a finite group of bureaucrats, we should enable every investor to act as a citizen-regulator.

“We should tap into the massive parallel processing power of people around the world by giving everyone the tools to track, analyze, and publicize financial machinations. The result would be a wave of decentralized… read more

How to see neurons of the deep brain for months at a time

January 17, 2011

Stanford scientists have devised a new method that not only lets them peer deep inside the brain to examine its neurons, but also allows them to continue monitoring for months.

The technique promises to improve understanding of both the normal biology and diseased states of this hidden tissue.

Other recent advances in micro-optics had enabled scientists to take a peek at cells of the deep brain, but their… read more

Oxygen-platinum bonding to improve fuel cells

December 1, 2004

Emory University researchers have created stable multiple chemical bonds between oxygen and platinum — once thought impossible because oxygen is extremely unstable when combined with certain metals.

Until this work, attempts to create metal-oxo species with elements such as gold, platinum, silver, iridium and rhodium have been unsuccessful. The breakthrough holds the potential for numerous applications in fuel cells, catalytic converters and emerging “green” chemistry.

Surface plasmons enhance nanostructure possibilities

September 19, 2007

Scientists from University College London and at the Queen’s University of Belfast have demonstrated a method of achieving ultrahigh light dispersion that makes use of surface plasmon polaritons on nanostructures.

Uses would be in such areas as quantum information processing, lab-on-chip applications for spectral analysis, chemistry and electronic engineering, and optical communications as signal processing devices.

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

Researchers Find Safer Way to Produce Stem Cell Alternative

March 2, 2009

An international team of researchers has developed what appears to be a safer way to create a promising alternative to embryonic stem cells, boosting hopes of sidestepping moral and political issues involved in destroying embryos.

The researchers produced the cells by using strands of genetic material, instead of potentially dangerous genetically engineered viruses, to coax skin cells into a state that appears biologically identical to embryonic stem cells.

Gene therapy reduces skin cancer from sunburn

December 13, 2004

University of Texas Southwestern Medical Center at Dallas have successfully tested the first gene therapy for skin cancer, using a mouse model for the disease xeroderma pigmentosum, or XP.

Humans with XP have a mutation that prevents the body from repairing DNA damaged by UV light. Mice with mutations in the gene Xpa suffer from XP and develop cancerous lesions on their skin within three weeks after UV light… read more

Novel Nanowires for Faster Memory

September 27, 2007

University of Pennsylvania researchers have pioneered a new technique for producing phase-change nanowires.

The technique could make it possible to build memory devices thousands of times faster and eight to ten times more energy efficient than memory currently on the market, such as flash.

The plan is to jolt the wires into an amorphous phase (the equivalent of a one in computer logic) or back into a crystalline… read more

AI Software to Command NASA Mission

May 30, 2001

AI software will make real-time decisions on a NASA satellite mission in 2002, NASA JPL announced today.

NASA’s Continuous Activity Scheduling, Planning Execution and Replanning (CASPER) software will guide three identical miniature satellites, which will be launched from the Space Shuttle and fly in formation as part of the Three Corner Sat mission.

CASPAR will make decisions based on the images it acquires and… read more

A new stem-cell-like treatment target for deadly brain tumors

August 2, 2012

A study by UT Southwestern Medical Center researchers  reveals new insight into why the most common, deadly kind of brain tumor in adults recurs and identifies a potential target for future therapies.

Glioblastoma multiforme (GBM) currently is considered incurable. Despite responding to initial therapy, the cancer almost always returns.

GBM is a fast-growing, malignant brain tumor that occurred in 15 percent of the… read more

Human fails Turing Test

March 5, 2009

Blogger James Bach was so unimpressed by the contrived and seemingly scripted responses to his typed questions to the Web Greeter site that be became convinced he was talking to an unthinking chatbot rather than a human.

We checked out the site. The robotic “welcome” message does give that impression at first, but web greeter Alex assured me that the “Turing test does not apply to humans”… read more

New graphic displays for the blind

December 23, 2004

A new, lower-cost mechanism may replace Braille for graphical tactile displays for the blind.

The displays use metallic films featuring various shape-memory alloys (SMAs) produced layer by layer on silicon wafers using thin-film technology. Display pixels are generated when the SMA metallic film is deformed by heat pulses. The movement of the films is then transferred to the touch panel via plastic pins that can be detected by the… read more
