Nature has long perfected the construction of nanomachines, but David Gonzalez and his fellow researchers from Eindhoven University of Technology and Utrecht University under the leadership of Spinoza Award winner Bert Meijer, have brought the construction of artificial supramolecular structures a step closer by.
By modifying a commonly used commercial infrared spectrometer to allow operation at long-wave terahertz frequencies, researchers at the National Institute of Standards and Technology (NIST) discovered an efficient new approach to measure key structural properties of nanoscale metal-oxide films used in high-speed integrated circuits.
NEW YORK, NY - MAY 6, 2009 - The Cardiovascular Research Foundation (CRF) announced that its landmark study comparing the safety and efficacy of drug-eluting stents and bare-metal stents was published today in The New England Journal of Medicine.
Research by a theoretical physicist at Indiana University shows that the crusts of neutron stars are 10 billion times stronger than steel or any other of the earth's strongest metal alloys.
Biotechnologists at UP Los Baños are hard at work putting the final touches to the prototype of a wastewater treatment system that uses bacteria.
Boulder, CO, USA - Hot topics include (1) opposition to the idea that chevron-shaped dunes are indicative of mega-tsunamis; (2) discovery of a complex microbial community that extends the fossil record of cavity-dwelling life by more than 1.5 billion years; (3) documentation of nanoscale, respirable cristobalite fibers in volcanic ash from Chaiten volcano and the likely adverse health effects;
Despite the common perception that total hip replacements last about 10 years, researchers at Rush University Medical Center have found that the devices are extremely durable, even 20 years after surgery.
Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. To catch such elusive moments, a camera must be able to capture millions or billions of images continuously with a very high frame rate. Conventional cameras are simply not up to the task.
AMES, Iowa - Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors.
ANN ARBOR, Mich.---A concrete material developed at the University of Michigan can heal itself when it cracks. No human intervention is necessary---just water and carbon dioxide.
CHAMPAIGN, Ill. -- Researchers at the University of Illinois have found a new way to make transistors smaller and faster. The technique uses self-assembled, self-aligned, and defect-free nanowire channels made of gallium arsenide.
The hydrino as defined by Dr Randell Mills would have a "true" 137 fractional quantum states as opposed to the relativistic interpertation suggested in a paper by Jan Naudts in 2005.
Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have succeeded in unlocking the potential of carbon dioxide - a common greenhouse gas - by converting it into a more useful product.
KINGSTON, R.I. - April 14, 2009 - Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours.
