During about 30 percent of all heart attacks, the patient experiences no symptoms. However, unmistakable signs of the attack remain in the bloodstream for days. MIT researchers, working with Massachusetts General Hospital's Cardiovascular Research Center, have now designed a tiny implant that can detect those signs, which could help doctors more rapidly determine whether a patient has had a heart attack.
EADS Innovation Works, the Group's corporate research arm, is working with university researchers to find a new solid state storage system for hydrogen. This technology would make it possible to use hydrogen as a clean alternative to traditional hydrocarbon-based fuels in aeroplane and car engines.
In a new study, researchers from UCLA's Henry Samueli School of Engineering and Applied Science and from the materials division of Australia's University of Queensland show the promise of surface-conduction channels in topological insulator nanoribbons made of bismuth telluride and demonstrate that surface states in these nanoribbons are "tunable" - able to be turned on and off depending on the position of the Fermi level.
An international team of researchers has discovered a new class of magnetic superhalogens - a class of atomic clusters able to exhibit unusual stability at a specific size and composition, which may be used to advance materials science by allowing scientists to create a new class of salts with magnetic and super-oxidizing properties not previously found.
The worldwide competition NanoArt 2011 is open to all artists 18 years and older. The online exhibition will open for public in April, 2011. Winners will be notified and published online on May 31, 2011.
The detection of circulating tumor cells is an emerging technique that can allow oncologists to monitor patients with cancer for metastasis or to evaluate the progress of their treatment. The gold particles, which are embedded with dyes allowing their detection by laser spectroscopy, could enhance this technique's specificity by reducing the number of false positives.
Mysterious expanding ice crystals in the moons of Saturn and Neptune may be of interest to future developers of microelectronics. Neutron scattering has discovered that methanol crystals that may be found in outer solar system 'ice lavas' have unusual expansion properties. The unexpected finding by a British planetary geologist will interest developers of nano-switches - single atom thick valves used in nanoelectronics.
New technology has made it possible to examine living cells in a microscope while at the same time collecting information that can be used to create mathematical models of the cells' behaviour - a new field of research known as 'systems microscopy'.
While there are many methods currently being used that can detect these threats, none allow for the unique fingerprinting of threat agents at trace levels. A research team at the U.S. Naval Research Laboratory, Electronic Science and Technology Division, has overcome this limitation with surface enhanced Raman scattering (SERS) using optically stimulated plasmon oscillations in nanostructured substrates.
Two new, high-powered mass spectrometers worth a total of more than $2 million will enable University at Buffalo scientists to conduct a variety of health and environmental studies without outsourcing lab work to institutions outside of Western New York.
The newly created 'African Network for Solar Energy' (ANSOLE) met at the Johannes Kepler University, Linz, Austria on February 4th last week in a dynamic and fruitful second symposium that saw it make great strides in planning the next phase of its development, taking the status of the network to a new level.
A new brochure "OECD Work on Environment" (pdf) highlights the OECD work on Environment for 2011-2012, covering green growth, climate change, biodiversity, water, eco-innovation, chemical and bio-safety, resource efficiency.
