Cornell researchers test carbon fiber to make tiny, cheap video displays
Engineers who develop microelectromechanical systems (MEMS) like to make their tiny machines out of silicon because it is cheap, plentiful and can be worked on with the tools already developed for making microelectronic circuits. There is just one problem: Silicon breaks too easily. view more (2006-08-23)
Lab-on-a-Chip Homes in on How Cancer Cells Break Free
Johns Hopkins engineers have invented a method that could be used to help figure out how cancer cells break free from neighboring tissue, an "escape" that can spread the disease to other parts of the body. view more (2009-03-19)
Creating unconventional metals
The semiconductor silicon and the ferromagnet iron are the basis for much of mankind's technology, used in everything from computers to electric motors. In this week's issue of the journal Nature (August 21st) an international group of scientists, including academic and industrial researchers from the UK, USA and Lesotho, report that they have... view more...

New microchip design could be the key to expanding mobile phone memory
Mobile phones could one day have the memory capacity of a desktop computer thanks to a microchip that mimics the functioning of the brain, scientists report today (9 September) in the journal Science. view more (2005-09-09)
New biochip helps study living cells, may speed drug development
Purdue University researchers have developed a biochip that measures the electrical activities of cells and is capable of obtaining 60 times more data in just one reading than is possible with current technology. view more (2006-10-23)
New system would use rotating magnetic field to detect pathogens
Researchers at Purdue and Duke universities have developed a technique that uses a magnetic field to selectively separate tiny magnetic particles, representing a highly sensitive method for potentially diagnosing disease by testing samples from patients. view more (2007-10-30)
Scientists moving closer to 'artificial noses'
These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. view more (2009-04-23)
Safer nanoparticles spotlight tumors, deliver drugs
Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless by-products. view more (2009-02-23)
Game utilizes human intuition to help computers solve complex problems
A new computer game prototype combines work and play to help solve a fundamental problem underlying many computer hardware design tasks. view more (2009-07-29)
Smaller microchips that consume less energy
To develop ever-smaller chips that consume less. These are the indispensable requirements of the current market for portable applications such as mobile telephone technology and biomedical systems, obtaining correct and trouble-free operation of the devices over the maximum possible duration of time. One of the techniques which, in fact, can be... view more... (2004-09-10)
UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the remote operation of micromachines a possibility. view more (2007-06-01)
Targeting the dosage compensation complex
Three independent research papers in the April 1 issue of G&D detail the chromosome-wide binding of the Drosophila dosage compensation complex (DCC) to the single male X chromosome, shedding new light on the mechanism of DCC targeting. view more (2006-03-17)
New findings could help hybrid, electric cars keep their cool
Understanding precisely how fluid boils in tiny "microchannels" has led to formulas and models that will help engineers design systems to cool high-power electronics in electric and hybrid cars, aircraft, computers and other devices. view more (2009-09-23)
Caltech scientists create robot surrogate for blind persons in testing visual prostheses
Scientists at the California Institute of Technology (Caltech) have created a remote-controlled robot that is able to simulate the "visual" experience of a blind person who has been implanted with a visual prosthesis, such as an artificial retina. view more (2009-10-20)
NIST team proves bridge from conventional to molecular electronics possible
Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the "evolutionary link" between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules. view more (2008-03-19)
Unique Quantum Effect Found in Silicon Nanocrystals
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., have shown that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals. MEG results in the formation of more than one electron per absorbed photon. view more (2007-07-26)
Melting defects could lead to smaller, more powerful microchips
As microchips shrink, even tiny defects in the lines, dots and other shapes etched on them become major barriers to performance. Princeton engineers have now found a way to literally melt away such defects, using a process that could dramatically improve chip quality without increasing fabrication cost. view more (2008-05-05)
Electronic “tongue” for environmental monitoring
UK researchers are developing a unique electronic ‘tongue’ that can be dipped into rivers or industrial effluent streams to ensure that the water does not contain anything sinister. The researchers, based at Cardiff University, have demonstrated that the ‘tasting’ part of the system can be fabricated from very small... view more... (2002-04-09)
