Biophysicists in Bochum have discovered a diode for protons: just like the electronic component determines the direction of flow of electric current, the 'proton diode' ensures that protons can only pass through a cell membrane in one direction. Water molecules play an important role here as active components of the diode.
QB3 biophysicists have traced with unprecedented resolution the paths of cargos moving through the nuclear pore complex (NPC), a selective nanoscale aperture that controls access to the cell's nucleus, and answered several key questions about its function.
The Technology Strategy Board and the Engineering and Physical Sciences Research Council in the UK have jointly allocated up to GBP7m to invest in highly innovative, collaborative research projects looking at the use of novel nanoscale technologies to enable the next generation of solar energy harvesting.
To watch a magician transform a vase of flowers into a rabbit, it's best to have a front-row seat. Likewise, for chemical transformations in solution, the best view belongs to the molecular spectators closest to the action.
The 30th International Sunbelt Social Network Conference (Sunbelt XXX) was held June 29 to July 4, 2010 in Trento, Italy. This is the official conference for the International Network for Social Network Analysis (INSNA).
Researchers at the Georgia Institute of Technology have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires.
A new 'smart materials' process - Multiple Memory Material Technology - developed by University of Waterloo engineering researchers promises to revolutionize the manufacture of diverse products such as medical devices, microelectromechanical systems (MEMS), printers, hard drives, automotive components, valves and actuators.
Purdue University researchers have developed a new type of pump for drug-delivery patches that might use arrays of microneedles to deliver a wider range of medications than now possible with conventional patches.
Measurements of slight forces - one yoctonewton is equivalent to the weight of a single copper atom on Earth - can be useful in force microscopy, nanoscale science, and tests of fundamental physics theories.
Researchers at the National Institute of Standards and Technology (NIST) have created 'quantum cats' made of photons (particles of light), boosting prospects for manipulating light in new ways to enhance precision measurements as well as computing and communications based on quantum physics.
Speakers made from carbon nanotube sheets that are a fraction of the width of a human hair can both generate sound and cancel out noise - properties ideal for submarine sonar to probe the ocean depths and make subs invisible to enemies.
Today, at the Engineering in Medicine and Biology Conference (EMBC) in Buenos Aires (Argentina), imec and its project partners announce the launch of the European Seventh Framework Project MIRACLE. The MIRACLE project aims at developing an operational lab-on-chip for the isolation and detection of circulating and disseminated tumor cells (CTCs and DTCs) in blood. The new lab-on-chip is an essential step towards faster and cost-efficient diagnosis of cancer.
Scientists speak of sputtering when energy-rich ions hit a solid object and cause atoms to be released from its surface. The phenomenon can be exploited to apply microscopically thin coatings to glass surfaces. A research team has developed a special sputtering technique that greatly increases the efficiency of the coating process.
