Microelectronic chips used to take pressure readings are very delicate. A new technology has been developed that makes pressure sensors more robust, enabling them to continue operating normally at temperatures up to 250 degrees Celsius.
A new intelligent system has been developed to help identify terrorists carrying explosives. Sensitive electronic noses capture the smell of the explosives; the system processes the acquired data, correlates it with individuals' movements - and ultimately tracks down the suspects.
A team of researchers in California and Massachusetts has developed a 'cocktail' of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors.
One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don't react well. A researcher has discovered the deviations in the miniscule but indispensable particles.
Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.
n the current issue of Science, Stuart Lindsay, director of Arizona State University's Center for Single Molecule Biophysics at the Biodesign Institute, along with his colleagues, demonstrates the potential of a method in which a single-stranded ribbon of DNA is threaded through a carbon nanotube, producing voltage spikes that provide information about the passage of DNA bases as they pass through the tube - a process known as translocation.
Federal research dollars will help South Dakota State University scientists build a first-of-its-kind microscope that could ultimately help scientists at SDSU and elsewhere develop better solar cells for converting sunlight to electricity.
Atomic Force F+E and Asylum Research, the technology leader in scanning probe/atomic force microscopy (AFM/SPM) announce the first European AFM in Biology Class to be held February 23-25, 2010 at Atomic Force Corporate office in Mannheim, Germany.
Am Leibniz-Institut fuer Festkoerper- und Werkstoffforschung Dresden (IFW) wird ab 1.1.2010 eine von der Deutschen Forschungsgemeinschaft (DFG) gefoerderte Emmy Noether-Nachwuchsgruppe eingerichtet. Mit dem auf 5 Jahre angelegten Projekt sollen die Wechselwirkungen der Elektronen erforscht und simuliert werden, die bei physikalischen Phaenomenen wie Supraleitung oder Magnetismus eine wichtige Rolle spielen.
It's the ultimate goal in the treatment of cancer: tailoring a person's therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers at Georgetown Lombardi Comprehensive Cancer Center report a significant advance in this field of research using a new chip that looks for hundreds of mutations in dozen of genes.
Transforming lead into gold is an impossible feat, but a similar type of 'alchemy' is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements.
Researchers from the University of Hong Kong and the Massachusetts Institute of Technology have published a study in the current issue of Cell Transplantation that explores ways to successfully keep stem cells 'forever young' during implantation by slowing their growth, differentiation and proliferation.
