Tiny Etch-a-Sketch

March 5, 2008
(Jeremy Levy)

University of Pittsburgh researchers have demonstrated a new technique that could be used to create rewritable logic circuits and denser computer memory.

Using an atomic force microscope (AFM), the researchers were able to draw electrically conductive paths to create nano-sized wires and dots that could be repeatedly erased and written.

Sensor Listens to Cells for Cancer

November 29, 2005

A tiny sensor that can hear the subtle electrical signals naturally emitted from cells could be used one day to listen for cancer.

The “microelectrode cell array” has the potential to detect tumors much earlier than current methods and help develop drugs that effectively kill cancerous cells.

The sensor is a specially designed semiconductor chip that contains an array of electrodes, each no wider than a human hair,… read more

NSS Labs Researcher Dillon Beresford expects to go public at the Black Hat security conference in Las Vegas on Aug. 2–3 with his research showing problems with Siemens computers used in power plants, heavy industry, and chemical plants.

In May, Beresford was pulled out of a Dallas hacking conference at the last minute when Siemens was unable to fix problems he’d found in the firmware of its S7… read more

Devil in the Details?

Some scientists are raising concerns about the potential of nanotechnology to produce weapons of mass destruction. (Requires paid access.)

FastForward Radio — The Technological Singularity

August 18, 2009

Phil Bowermaster and Stephen Gordon will interview Ray Kurzweil Tuesday evening on FastForward Radio at 10:30 Eastern/7:30 Pacific, with audience participation by text chat.

Language of a fly proves surprising

March 10, 2008

Los Alamos, Princeton University, and Indiana University research fundamentally alters earlier beliefs about how neural networks function and could provide the basis for intelligent computers that mimic biological processes.

The researchers developed a novel way to view the world through the eyes of a common fly and partially decode the insect’s reactions to changes in the world around it.

They used electrodes to tap into motion-sensitive neurons in… read more

Trace of Human Stem Cells Put in Unborn Mice Brains

December 13, 2005

Scientists have created mice with small amounts of human brain cells in an effort to make realistic models of neurological disorders like Parkinson’s disease.

Those mice were each born with about 0.1 percent of human cells in each of their heads, raising ethical concerns about mixing human and animal cells in stem cell and cloning research.

Three researchers have applied for a patent that contemplates fusing a complete… read more

Live from the Future of Life

February 20, 2003

Participants debated stem cell research and examined the genomics revolution, the anti-evolutionary fervor and the promise of nanotechnology in medicine on the first day of TIME’s “The Future of Life” conference, celebrating the 50th anniversary of the discovery of DNA.

Cooperative Cybercars: A Question Of Priorities

August 27, 2009

European researchers in the CyberCars2 project have developed new control systems that let driverless vehicles (“cybercars”) exchange data and coordinate their movements — a atep toward high-throughput, efficient automated transportation systems that could be deployed in traffic-free zones.

Toward Cheaper, Robust Solar Cells

March 13, 2008

An Ecole Polytechnique Federale de Lausanne scientist is working on more advanced versions of dye-sensitized solar cells that could be more robust and even cheaper to make than current versions, thanks to a new combination of electrolyte and dye.

Dye-sensitized solar cells solar cells are cheaper to make than conventional silicon photovoltaic panels. In principle, they could be used to make power-generating windows and building facades, and they could… read more

The 50 Greatest Gadgets of the Past 50 Years

December 25, 2005

PC World’s list of the top tech gadgets of the last half century, rated by “usefulness, design, degree of innovation, and influence on subsequent gadgets, as well the ‘cool factor,’” includes Sony Walkman (1979), Apple iPod (2001), and a tie between ReplayTV RTV2001 and TiVo HDR110 (1999) — the top three.

Other cool items include iRobot Roomba Intelligent Floorvac (2002), Sharp Wizard OZ-7000 (1989), and MITS Altair 8800 (1975).

Toshiba boffins prep laptop fuel cell

March 6, 2003

Toshiba has figured out how to power a portable computer using fuel cell technology without the need for a power unit larger than the PC itself.

An international team of researchers has designed Graphone, a new magnetic nanomaterial made by adding hydrogen atoms to graphene (a form of carbon), with the potential for novel applications in spintronics devices for memory and data processing.

Blue LEDs to reset tired truckers’ body clocks

March 19, 2008

Blue LEDs in truck cabs and truck stops could be the key to reducing accidents caused by drowsy drivers by convincing the brain it’s morning, say Rensselaer Polytechnic Institute researchers.

Nearly 30% of all fatal accidents involving large trucks in the US happen during the hours of darkness.

The lie detector you’ll never know is there

January 5, 2006

THE US Department of Defense has revealed plans to develop a lie detector that can be used without the subject knowing they are being assessed.

The Remote Personnel Assessment (RPA) device will also be used to pinpoint fighters hiding in a combat zone, or even to spot signs of stress that might mark someone out as a terrorist or suicide bomber.
