Bigger not necessarily better, when it comes to brains
Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, say scientists at Queen Mary, University of London. view more (2009-11-18)
Small optical force can budge nanoscale objects
With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported. view more (2009-11-18)
Working together to design robust silicon chips
Designers of high-speed silicon chips have often had to compromise on performance levels for their integrated circuit designs because of physical weaknesses appearing during design verification or even in production. view more (2009-11-13)
Caltech scientists develop DNA origami nanoscale breadboards for carbon nanotube circuits
In work that someday may lead to the development of novel types of nanoscale electronic devices, an interdisciplinary team of researchers at the California Institute of Technology (Caltech) has combined DNA's talent for self-assembly with the remarkable electronic properties of carbon nanotubes, thereby suggesting a solution to the long-standing... view more...

Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
Quantum computer chips now 1 step closer to reality
In the quest for smaller, faster computer chips, researchers are increasingly turning to quantum mechanics -- the exotic physics of the small. The problem: the manufacturing techniques required to make quantum devices have been equally exotic. That is, until now. view more (2009-10-16)
Color sensors for better vision
The car of the future will have lots of smart assistants onboard - helping to park the car, recognize traffic signs and to warn the driver of blind spot hazards. view more (2009-10-06)
Understanding a cell's split personality aids synthetic circuits
As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way. view more (2009-10-05)
Researchers develop an integrated treatment for veterans with chronic pain and posttraumatic stress
The wars in Iraq and Afghanistan have resulted in a growing number of soldiers evacuated to the United States for comprehensive care for physical and psychological trauma. view more (2009-09-30)
Discovery Brings New Type of Fast Computers Closer to Reality
Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality. view more (2009-09-28)
Racial Disparities in Diabetes Prevalence Linked to Living Conditions
The higher incidence of diabetes among African Americans when compared to whites may have more to do with living conditions than genetics, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2009-09-22)
Premium info for car drivers
What will the weather be like over the next few hours on the A3 between Nuremberg and Würzburg? Could fog be a problem? A new system will enable automakers to offer their customers additional services - such as weather information or details of vacant parking spaces. view more (2009-09-11)
Graphitic memory techniques advance at Rice
Advances by the Rice University lab of James Tour have brought graphite's potential as a mass data storage medium a step closer to reality and created the potential for reprogrammable gate arrays that could bring about a revolution in integrated circuit logic design. view more (2009-09-10)
'NanoPen' may write new chapter in nanotechnology manufacturing
Researchers in California are reporting development of a so-called "NanoPen" that could provide a quick, convenient way of laying down patterns of nanoparticles - from wires to circuits - for making futuristic electronic devices, medical diagnostic tests, and other much-anticipated nanotech applications. view more (2009-09-02)
Nuclear fusion research key to advancing computer chips
Researchers are adapting the same methods used in fusion-energy research to create extremely thin plasma beams for a new class of "nanolithography" required to make future computer chips. view more (2009-08-19)
Organic electronics a two-way street, thanks to new plastic semiconductor
Plastic that conducts electricity holds promise for cheaper, thinner and more flexible electronics. This technology is already available in some gadgets -- the new Sony walkman that was introduced earlier this summer and the Microsoft Zune HD music player released last week both incorporate organic light-emitting electronic displays. view more (2009-08-18)
CSHL study finds short- and long-term memories require same gene but in different circuits
Why is it that you can instantly recall your own phone number but have to struggle with your mental Rolodex to remember a new number you heard a few moments ago? view more (2009-08-18)
Caltech and IBM scientists use self-assembled DNA scaffolding to build tiny circuit boards
Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns-or "DNA origami"-on surfaces that are compatible with today's semiconductor manufacturing equipment. view more (2009-08-18)
Experiments at UCSB push quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science. view more (2009-08-12)
