Intel claims power breakthrough

September 22, 2005

Intel has announced a new chip manufacturing process which it claims could dramatically cut power consumption, and boost battery life by up to 1,000 per cent.

Stretchable Silicon Sensors Could Speed Up Heart Surgery

May 5, 2011

Stretchable silicon, a new surgical technology, uses hundreds of thousands of stretchable sensors embedded on the surface of a balloon catheter to map electrical problems in the heart, such as atrial fibrillation.

The technology was recently developed at MC10 Inc. and successfully tested on animals by John Rogers at the University of Illinois at Urbana-Champagne and colleagues.

Conventional balloon catheters… read more

Venter to Bio World: Exa-Byte Me

November 13, 2002

Craig Venter, delivering the opening address yesterday at the BioITWorld conference here, said that computer power will be the limiting factor in crunching, storing, and manipulating the data necessary for linking the promise of genomics to insights into gene function, protein interaction, and personalized medicine. To underscore his point, he said the Celera computers that sequenced the human genome – the 1.5 teraflop, 120 terabyte machines that took up 6,000… read more

Why microbes are smarter than you thought

June 30, 2009

Examples of “intelligent” behavior by microbes include chemical conversations and “quorum sensing” to decide when to launch an attack on their host.

Large-Scale Rewritable Holograms

February 8, 2008

A holographic display developed by researchers at the University of Arizona and at Nitto Denko Technical Corporation can be repeatedly written to and erased.

The University of Arizona researchers developed a new polymer-based material that encodes information using electric fields. It could eventually allow for life-sized displays of people and objects the size of cars that could be refreshed every few minutes.

PNA Molecules Could Be Used To Build Nanodevices

October 4, 2005

Carnegie Mellon University researchers have shown that the binding of metal ions can mediate the formation of peptide nucleic acid (PNA) duplexes from single strands of PNA that are only partly complementary. This result opens new opportunities to create functional, three-dimensional nanosize structures such as molecular-scale electronic circuits, which could reduce by thousands of times the size of today’s common electronic devices.

Google to launch chrome laptops in June

May 12, 2011

Google Inc. previewed the first laptops running the company’s Chrome operating system, machines that will go on sale next month as part of Google’s challenge to Microsoft Windows.

The “Chromebooks” use operating-system software based largely on Google’s Chrome Web browser.

The laptops are designed primarily to run Web-based applications, including word-processing and games. Because they rely on Web-based apps, the Chrome devices boot up in eight seconds, the company… read more

Dead Air

November 25, 2002

Cell phones and the wireless industries of the future are snarled by a critical shortage of airwaves.

Solutions are on the way. Intel has discovered how to build entire radios in silicon chips. This and other new wireless technologies like cognitive radio, ultrawideband, software-defined radio and mesh networks could allow for spectrum sharing without interference, which the FCC is considering.

Is your city prepared for a home-made nuke?

July 9, 2009

For many people, the safest option would be to seek shelter in buildings or underground.

Just staying inside could slash the immediate death toll from radiation by up to a factor of 100, or even 1000.

Progenitor cells coud prop up the patient’s immune system while the bone marrow recovers.

Looks familiar

February 13, 2008

The 3D reconstruction of a face from a single 2D image could be made faster and more accurate with new software being developed by scientists at York University.

Dr. William Smith, a lecturer in computer vision at York, aims to combine the advantages of two face-recognition techniques to challenge the most advanced method for recovering 3D shapes when there is only one image to work from, such as an… read more

Strengthening fragile forests of carbon nanotubes

Brigham Young University (BYU) researchers have created stronger microstructures that can form precise, tall and narrow 3-D shapes for microelectromechanical systems (MEMS).

MEMS are ultra-tiny devices, often built on the scale of microns (millionths of a meter). Conventional MEMS structures tend to be made out of silicon-based materials familiar to the micro-electronics industry, but this ignores a suite of useful materials such… read more

Bird flu outbreaks expected in more countries

October 18, 2005

The deadly H5N1 strain of bird flu is likely to spread to more and more countries, a World Health Organization official warned on Monday.

The strain, which has killed over 60 people in southeast Asia, appears to have travelled extensively in the latter half of 2005. It has affected birds in China, Mongolia, Russia, Kazakhstan and most recently reached Europe.

It is now believed that the virus has… read more

Digital imaging software to create a ‘Google Earth’ view of the bladder

May 17, 2011

UW Scope

A new system that would use an ultrathin laser endoscope with software to stitch together images from the scope’s path to create a full, 3-D panorama of a bladder’s interior has been proposed by researchers at the University of Washington.

The user interface projects the reconstructed organ onto a spherical ball or onto a flat map. The resulting mosaic matches the images to a single… read more

The World According to Google

December 12, 2002

Google is transforming the masses into data-miners and becoming a cultural phenomenon.

But its founders have even bigger plans. “The ultimate search engine would be smart; it would understand everything in the world,” says Larry Page. “I view Google as a way to augment your brain with the knowledge of the world,” says Sergey Brin. “It will be included in your brain.”

Mammoth Telescope to Be Built in Hawaii

July 22, 2009

A giant telescope with a primary mirror that measures 30 meters across, giving it nine times more collecting surface than the biggest telescopes on Earth today, will be constructed in Hawaii by 2018.
