- Nanofabrication method paves way for new optical devices
10-05-2007 · EurekAlert!
An innovative and inexpensive way of making nanomaterials on a large scale, developed at Northwestern University, has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties. These include optical nanomaterials called "plasmonic metamaterials." The new fabrication technique, known as soft lithography, offers many significant advantages over existing techniques, including the ability to scale-up the manufacturing process to produce devices in large quantities.

- Delft nano-detector very promising for remote cosmic realms
01-17-2007 · EurekAlert!
A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. Merlijn Hajenius developed these sensors for Delft University of Technology's Kavli Institute of Nanoscience, in cooperation with the SRON Netherlands Institute for Space Research. He will receive his PhD degree on 19 January based on this research subject.

- Reliable cup of coffee
04-13-2007 · EurekAlert!
Dutch-sponsored researcher Laura Brandán Briones has elevated software testing to a higher level. She improved both the tests and the method to determine the reliability of the tests. This means, for example, that washing machines and coffee machines can be tested far better before they are launched on the market.

- US Climate Change Science Program making good progress in documenting and understanding changes
09-13-2007 · EurekAlert!
Climate change research directed by the federal government has made good progress in documenting and understanding temperature trends and related environmental changes on a global scale, says a new report from the National Research Council. The ability to predict future climate changes also has improved, but efforts to understand the impact of such changes on society and analyze mitigation and adaptation strategies are still relatively immature, added the committee that wrote the report.

- Quality versus quantity -- Transforming kidney transplant policy
05-17-2007 · EurekAlert!
A new article published in American Journal of Transplantation examines the dilemmas faced in trying to change kidney transplant policy; addressing the need to balance the benefits of immediate transplants with those to be had from waiting for a more suitable match. The article highlights some of the important points to be considered in any new policy-making, and suggests a new method for allocation, whereby the patients are involved in the decision process.

- Iowa State physicist leads team designing detector for international particle collider
04-13-2007 · EurekAlert!
John Hauptman, an Iowa State University professor of physics and astronomy, is leading an international team that's designing a detector for the proposed International Linear Collider. The collider would be about 19 miles long and accelerate electrons and positrons to nearly the speed of light. The particles would collide at the center of the machine at extremely high energies. Collider detectors would record those collisions. Physicists expect the collisions to create new particles and help them understand how the universe works.

- New culture method for hepatitis C virus uses primary hepatocytes and patient serum
01-23-2007 · EurekAlert!
Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et al, "Hepatitis C virus replication in transfected and serum-infected cultured human fetal hepatocytes," appears in the February issue of the American Journal of Pathology.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for correlating the results of microscopic imaging techniques in a way that could lead to improved understanding, diagnosis, and possibly treatment of a variety of disease conditions, including Alzheimer's disease. The Laboratory has filed a U.S. provisional patent application for the invention.
