Terabit-class data pipes movies in an instant

November 19, 2007

Researchers at Japan’s Tohoku University have tweaked existing quadrature amplitude modulation (QAM) protocols to enable standard fiber-optic cables to carry data at hundreds of terabits per second.

Future chip choice–silicon or plastic?

October 15, 2001

Promising research efforts are under way to combine silicon and plastic, using organic polymers as material for the production of microelectronics, including transistors and displays.
Organic polymers are molecules that contain a long string of carbon atoms and make versatile plastics.

The research team headed by Bertram Batlogg of the Swiss Federal Institute for Technology from the ETH in Zurich, Switzerland, was recently honored with one of the most… read more

Tweet this: Rapid-fire media may confuse your moral compass

April 14, 2009

A study by the Brain and Creativity Institute at the University of Southern California raises questions about the emotional cost — particularly for the developing brain — of heavy reliance on a rapid stream of news snippets obtained through television, online feeds, or social networks such as Twitter.

“If things are happening too fast, you may not ever fully experience emotions about other people’s psychological states and that would… read more

How spooky is Foursquare?

March 17, 2011

Do you really want people to know where you are, based on your mobile phone’s GPS or a check-in at a Foursquare place? This restaurant story by Brad Feld (Do More Faster) may give you second thoughts.

Barrett: No end in sight for Moore’s Law

March 2, 2005

Moore’s Law will boost chip abilities for many years to come, Intel CEO Craig Barrett predicted on Tuesday.

Barrett predicted that traditional chipmaking technology will permit features as small as 5 nanometers–about the width of 50 hydrogen atoms–to be used on processors.

He mentioned three options for replacing conventional CMOS technology: quantum dot, polymer layer, and nanotubes.

Your Robotic Personal Assistant

November 28, 2007

New software lets robots pick up objects they have never seen before–an important step toward creating multifunctional domestic helpers.

Some roboticists are building perception systems for robots that look for certain features on objects that are good for grasping. A Stanford team has approached the problem by collecting a number of previously fragmented technologies, such as computer vision, machine learning, speech recognition, and grasping hardware, and put… read more

A Talk with the Brain behind Blue Gene

November 9, 2001

On Nov. 9, IBM will disclose a partnership with Lawrence Livermore National Labs to work on a wide range of scientific applications for Blue Gene. This will be the world’s fastest supercomputer, being designed to operate a hundred times faster than today’s speediest machines. The objective: to simulate how proteins fold themselves into their unique patterns.
With Blue Gene, IBM is trying to set a new supercomputer speed limit –… read more

GaAs self-assembled nanowires could make chips smaller and faster

April 21, 2009

Researchers at the University of Illinois have found a new way to make transistors smaller and faster (with diameters as small as 5 nanometers), using self-assembled, self-aligned, and defect-free nanowire channels made of gallium arsenide.

Neurons grow into semiconductor tubes: future intelligent chips?

March 23, 2011

Nanomembrane Tubes

Researchers at the University of Wisconsin, Madison, led by Minrui Yu, have successfully induced nerve cell tendrils to grow through semiconductor tubes using strained silicon (Si) and germanium (Ge) nanomembranes as a cell culture substrate.

In many neural culture studies, neurite migration on a flat, open surface does not reflect the three-dimensional (3D) microenvironment in vivo.

Their xperiments show that the SiGe substrate and the tube fabrication process… read more

Zombie PCs being sent to steal IDs

March 16, 2005

Bot nets, collections of compromised computers controlled by a single person or group, have become more pervasive and increasingly focused on identity theft and installing spyware.

The large networks of compromised computers are now a tool for groups of criminals bent on making money through identity fraud or adware installation. A person whose computer is infected with bot software runs the risk of having sensitive information such as account… read more

Will you soon be able to buy your own bladder?

December 6, 2007

Eventually, scientists will take one of the white spheres floating in the jars — the scaffolds — and add layers upon layers of human bladder cells, then ship the organ to a surgeon, who will implant it in the body of its donor. From biopsy to surgery, Tengion’s process takes six to eight weeks.

That patient just bought a new bladder, made out of her own cells. This may… read more

Taking Curl for a Whirl

December 5, 2001

A new Web site technology called “Curl” that makes browsing and Web site development faster has been developed by Web pioneer Tim Berners-Lee and other MIT experts.

Curl’s speed acceleration is due to the use of a single application to run diverse content and a downloadable browser plug-in that uses the site visitor’s own CPU to process pages built with Curl for page redraws, graphics processing, database duties and… read more

Nanosensor Arrays ‘Smell’ Cancer

April 28, 2009

Israel Institute of Technology researchers used a network of 10 sets of chemically modified carbon nanotubes to create a multicomponent sensor capable of discriminating between a healthy breath and one characteristic of lung cancer patients.

Using 10 different organic coatings, the investigators created field-effect transistors comprising random networks of each of the different coated nanotubes, and the resulting array produces a characteristic change in electrical output when exposed to… read more

Probe captures high-resolution images of nanomaterials

March 30, 2011

Nano Materials

Scientists at Berkeley Lab’s Molecular Foundry have pioneered a new chemical mapping method that provides unprecedented insight into materials at the nanoscale, says Alexander Weber-Bargioni, a postdoctoral scholar in the Imaging and Manipulation of Nanostructures Facility at the Foundry.

The team designed and fabricated a coaxial antenna capable of focusing light at the nanoscale using a state-of-the-art focused ion beam tool. The antenna consists of… read more

26 Most Fascinating Entrepreneurs

March 27, 2005

Ray Kurzweil has been named to Inc. magazine’s “26 Most Fascinating Entrepreneurs” list “because he is Edison’s rightful heir.”

Kurzweil in number 8 in Inc.’s slide show profiling innovative entrepreneurs, joining Richard Branson, Martha Stewart, Trip Hawkins, Michael Dell, and others.

“Kurzweil’s businesses rely on one basic theme: pattern recognition,” the Inc. slide show explains. “‘I gather as much data as I can to develop patterns at every… read more
