First Molybdenite microchip

December 5, 2011

Monolayer molybdenum disulfide membranes

École Polytechnique Fédérale de Lausanne (EPFL) Laboratory of Nanoscale Electronics and Structures (LANES) scientists have made the first molybdenite microchip, using smaller and more energy efficient transistors. Molybdenite, a new and very promising material, can surpass the physical limits of silicon in terms of miniaturization, electricity consumption, and mechanical flexibility, the scientists say.

New Technique Makes Tissues Transparent

February 14, 2008

California Institute of Technology, Ecole Polytechnique Federale de Lausanne, and MIT researchers have developed a technique that counteracts the scattering of light and removes the distortion it creates in images.

The “turbidity suppression by optical phase conjugation” (TSOPC) techniques used a holographic crystal to record the scattered light pattern emerging from a 0.46-mm-thick piece of chicken breast. They then holographically played the pattern back through the tissue section to… read more

Odd behavior and creativity may go hand-in-hand

September 7, 2005

New research on individuals with schizotypal personalities — people characterized by odd behavior and language but who are not psychotic or schizophrenic — offers the first neurological evidence that they are more creative than either normal or fully schizophrenic individuals, and rely more heavily on the right sides of their brains than the general population to access their creativity.

Microwave weapon will rain pain from the sky

July 23, 2009

The US Air Force is developing an multibeam airborne version of its Active Denial System, which uses high-frequency microwaves to heat the skin, creating a painful sensation without burning that strongly motivates the target to flee.

Molecules power nanoscale computers

October 25, 2002

IBM Almaden Research Center researchers have developed a new kind of computing process that relies on the motion of molecules rather than the flow of electrons. The logic gates use cascades of carbon monoxide molecules to transfer data.

Devices made in this way have dimensions on the scale of nanometers, several orders of magnitude smaller than existing silicon-based components.

The researchers demonstrated a three-input sorter that uses several… read more

This box sends your health data straight to the cloud

December 12, 2011

2net

A new platform from Qualcomm called 2net uses a simple box in the home that detect signals from medical monitoring devices of dozens of makers, and dispatches them by cellular connection to a cloud database that can be accessed by medical staff as well as patients.

 

Future of video game industry taking shape at GDC

February 20, 2008

“When Ray Kurzweil, the author of The Singularity is Near and one of the most noted futurists around, takes the stage at GDC 2008 in San Francisco on Thursday to talk about ‘the next 20 years of gaming,’ he’ll be weighing in at a moment in the industry’s existence when the lines between games and Hollywood and advertising are blurring,” says CNET.

Stem Cells Help More Mice Walk

September 19, 2005

Injections of human stem cells in mice seem to directly repair some of the damage caused by spinal cord injury, going beyond previous research by repairing myelin cells, which create the biological insulation that nerve fibers need to communicate.

A number of neurological diseases, such as multiple sclerosis, involve loss of that insulation.

‘Temporal cloaking’ could bring more secure optical communications

June 7, 2013

Output for a particular sequence of ones and zeros.<br />
Although the binary data specified on the bottom of the plot are clearly detected<br />
when the cloak is off, the voltage swings indicative of bit transmission are<br />
suppressed to a nearly flat line when the cloak is on.

 

Purdue University researchers have demonstrated a method for “temporal cloaking” of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.

“More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the existing telecommunications infrastructure,” said Purdue graduate student Joseph Lukens, working with … read more

How to Make an Electronic Display With Paper and Mood-Ring Ink

August 3, 2009

Using cheap materials that anyone can order by mail, scientists built several color-changing electronic displays on sheets of ordinary paper, using thermochromic ink, found in mood rings and disposable thermometers (when its temperature changes, so does its color).

By coating one side of the paper with ink, and affixing metal heating elements to the other, a Harvard scientist built a makeshift monitor. These simple devices could provide the readout… read more

Chemists Build Body Fluid Battery

November 11, 2002

Our bodies could one day power their own electronic implants. Chemists have developed a miniature battery that could run on bodily fluids to drive sensors to monitor our health. The biofuel cell converts directly into electricity the energy produced when glucose reacts with oxygen during normal metabolism.

The Internet gets physical

December 19, 2011

The Internet of Things or the Industrial Internet is here. Across many industries, products and practices are being transformed by communicating sensors and computing intelligence.

Examples: Nest Labs (a digital thermostat), General Electric (smart hospital room), IBM (2,000 projects worldwide that fit in the Smarter Planet category).

“We’re going to put the digital ‘smarts’ into everything,” said Edward D. Lazowska, a computer scientist at the University of Washington.… read more

WorldWide Telescope peers into Big Dipper

February 28, 2008

Microsoft presented its WorldWide Telescope (WWT) program today at the TED conference.

WorldWide Telescope, which is similar to the sky feature in Google Earth but much more expansive, is a virtual map of space that features tens of millions of digital images from sources like the Hubble telescope and the Sloan Digital Sky Survey.

From the desktop, the technology lets people pan and zoom across the night sky,… read more

Google offers S.F. Wi-Fi — for free

October 2, 2005

Google Inc. has offered to blanket San Francisco with free wireless Internet access.

The proposal raises speculation that Google intends to create a free national Wi-Fi network.

Robots to get their own operating system

August 10, 2009

The Robot Operating System or ROS, an open-source set of programs meant to serve as a common platform for a wide range of robotics research, is being developed and used by teams at Stanford University, MIT, and the Technical University of Munich, among others.
