NTT Develops Three-Dimensional Nanofabrication Using Electron Beam Lithography

February 4, 2004
World

NTT has created an electron-beam lithography system that enables the fabrication of 3D structures down to the 10-nanometer level.

Plans call for applying this technique to nanofabrication of semiconductors and other nanoelectronic devices.

The process achieves a resolution 100 times that of conventional methods using an optical or X-ray beam, enabling fast 3D fabrication and patterning of nanoscale devices.

H.P. Sees a Revolution in Memory Chip

April 8, 2010

Hewlett-Packard scientists plan today to report advances in the design of memristors, a new class of devices capable of replacing transistors, using a vast three-dimensional array, which allows for ultradense computing devices.

HP now has working 3-nanometer memristors that can switch on and off in about a nanosecond. HP says it could have a competitor to flash memory in three years that would have a capacity of 20 gigabytes… read more

New Google tool aims to provide more insight into online searches

August 7, 2008

Google has launched Google Insights for Search, an extension of Google Trends, designed to be used by advertisers, small business owners, academics and others.

Like Google Trends, the Insights software lets users type in search terms and then see search volume patterns over time and the top related and rising searches. But users can also now compare volume trends across multiple search terms, vertical industry categories, geographic regions and… read more

2006: The year in tech

December 27, 2006

Gut-crawling robots as an alternative to colonoscopy, quasar encryption, a two-legged robot, and a working “invisibility cloak” are some of this year’s tech highlights.

Noise boosts nanotube antennas

February 12, 2004

Researchers at the University of Southern California have shown that the right amount of noise can enable carbon nanotube transistors to detect weak electrical signals, making nanotubes useful as microscopic antennas in communications devices, including cell phones.

This is the same effect — stochastic resonance — that neurons use to communicate in biological brains.

Possible uses include secure spread-spectrum communications, processing pixel-based image data, sensing chemical and biological… read more

Maxed out: Testing humans to destruction

April 20, 2010

How far can you push the human body before it fails? New Scientist explores 12 extremes of endurance, from vacuum exposure to memory marathons, in a special feature.

Spin flip trick points to fastest RAM yet

August 14, 2008

Researchers in Germany have built a Magnetoresistive random access memory (MRAM) system that is 10 times faster than existing MRAM systems.

MRAM is a faster and more energy efficient version of the RAM used in computers today, and hardware companies think it will in a few years dominate the market.

Homing nanoparticles pack multiple assault on tumors

January 8, 2007

Burnham Institute for Medical Research researchers have developed nanoparticles that home in on tumors and bind to their blood vessels, and then attract more nanoparticles to the tumor target.

They demonstrated that the homing nanoparticle could be used to deliver a “payload” of an imaging compound, and in the process act as a clotting agent, obstructing as much as 20 percent of the tumor blood vessels to inhibit growth.… read more

US military creates second Earth

February 24, 2004

The US Army is building a second version of Earth on computer to help it prepare for conflicts around the world.

The project aims to help the US Army plan future conflicts. The software Earth is being created for the US Army by gaming company There. It is planning to model the entire planet at a scale that would make it possible to walk across the United States if… read more

New Way To Guide A Car: With Your Eyes, Not Hands

April 26, 2010

German researchers have developed a new technology, “eyeDriver,” that lets drivers steer cars going 31 mph (50 kph) using only their eyes.

Researchers link cocoa flavanols to improved brain blood flow

August 19, 2008

Cocoa flavanols, the unique compounds found naturally in cocoa, may increase blood flow to the brain, according to research by Harvard medical scientists.

Study participants who regularly drank a cocoa flavanol-rich beverage had an eight percent increase in brain blood flow after one week, and 10 percent increase after two weeks.

When the flow of blood to the brain slows over time, the result may be structural damage… read more

Doomsday draws two minutes closer

January 18, 2007

The Bulletin of Atomic Scientists has moved the hands of its Doomsday Clock to five minutes before midnight — the metaphorical marker of the end of humanity.

Two factors prompted the Bulletin’s board to move the clock forward by two minutes: the spread of nuclear weapons and climate change.

The chief reason for the move is the dawn of a “second nuclear age,” in which far more countries… read more

Plastic on Steroids

March 9, 2004

Research in electroactive polymers (EAPs), a type of artificial muscle, seems to have finally paid off with some useful products. Among them: powerful pumps and motors, nearly silent propulsion technologies, and novel drug-delivery systems.

EAPs could fundamentally alter drug delivery. Marc Madou of UC Irvine is developing implantable, matchstick-sized capsules with microscopic pores. When sensors detect that a patient needs, say, more insulin, artificial muscles open valves under the… read more

Army of smartphone chips could emulate the human brain

May 4, 2010

Steve Furber, a professor of computer engineering at the University of Manchester, is attempting to model the synaptic weights and coordinated voltage spikes of the human brain in a 1-billion-neuron silicon brain system called Spinnaker (Spiking Neural Network Architecture).

The chips, under construction in Taiwan, contain 20 ARM processor cores, each modelling 1000 neurons. With 20,000 neurons per chip, 50,000 chips will be needed to reach the target of… read more

Mexicans get microchipped over kidnapping fears

August 25, 2008

Affluent Mexicans worried by soaring kidnapping rates are spending thousands of dollars to implant tiny transmitters under their skin so satellites can help find them.
