Automated analyzer for complex nuclear waste provides rapid results
03-28-2007 · EurekAlert!Identifying and quantifying specific alpha- and beta-emitting radionuclides in liquid solutions can be challenging and time consuming -- typically taking from days to weeks to get results back from an analytical laboratory. But, when an industrial process-scale plant requires that an accurate, reliable analysis be completed in near real-time from samples retrieved directly from the process line, the challenge could be overwhelming. However, scientists at Pacific Northwest National Laboratory have assembled a robust, fully automated prototype process monitor to meet demanding production needs.

- Evidence From Ice Age That Climate Change Can Have A Rapid Effect On Ocean Circulation
10-09-2006 · ScienceDaily
Sudden shifts in temperature over Greenland and tropical rainfall patterns during the last ice age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. The results provide further evidence that climate change can have a direct and rapid impact on ocean circulation and chemistry.

- What's going on in the body? Advanced time-of-flight PET takes a superior 'look'
06-04-2007 · EurekAlert!
Moving from computer simulation to patient images, researchers are now demonstrating the benefits that time-of-flight/PET imaging can provide for cancer patients. The result? Superior images and shorter patient scan times for starters, according to a study released at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals, June 2-6 in Washington, D.C.

- Virginia Tech's System X supercomputer provides super tool for simulation of cell division
01-30-2007 · EurekAlert!
Virginia Tech researchers in computer science and biology have used the university's supercomputer, System X, to create models and algorithms that make it possible to simulate the cell cycle -- the processes leading to cell division. They have demonstrated that the new mathematical models and numerical algorithms provide powerful tools for studying the complex processes going on inside living cells.

- New clinical trial results show how personalized medicine will alter treatment of genetic disorders
12-26-2007 · EurekAlert!
In the latest edition of the New England Journal of Medicine, Eric Hoffman, PhD, posits that the results of a clinical trial involving a new treatment for Duchenne muscular dystrophy provides a proof-of-principle for personalized molecular medicine. He writes that advances allowing for systemic delivery of such drugs and provide proof of no long term toxicity for recipients are necessary but will likely come in short order. Moving forward, FDA regulations will prove critical for appropriate labeling and marketing of such personalized treatments.

- Portable electricity, life-like prosthetics on the way
11-16-2007 · EurekAlert!
The technology that makes a cell phone vibrate is the same technology that provides more natural movements to prosthetic limbs. A University of Houston research team is working on recreating and enhancing this technological effect, which, if successful, could result in better prosthetic movements and also provide instant electrical power for soldiers and others through the simple act of walking.

- Study: Sticking to the sand might not be such good, clean fun for beachgoers
08-07-2007 · EurekAlert!
Microbes that result in beach closures and health advisories when detected at unsafe levels in the ocean also have been detected in the sand, according to a study by Stanford University scientists.The study found that sand at beaches all along the California coast contained some level of fecal indicator bacteria. At one popular beach in Monterey, Calif., they found evidence of human waste -- raising doubt about the commonly held belief that some fecal indictor bacteria occur naturally in the sand and are therefore benign.

- Kids allowed to join groups for complex reasons
02-23-2007 · EurekAlert!
New research at the University of Maryland looks at why kids decide to include -- and exclude -- other kids from their group of friends. It turns out the decision making process is much more complex than previously believed, and could even provide insights into how to intervene when children are rejected by their peers.

- Three first-ever atomic nuclei created at NSCL; new super-heavy aluminum isotopes may exist
10-24-2007 · EurekAlert!
Researchers at Michigan State University's National Superconducting Cyclotron Laboratory, have created three never-before-observed isotopes of magnesium and aluminum. The results not only stake out new territory on the nuclear landscape, but also suggest that variants of everyday elements might exist that are heavier than current scientific models predict. The findings appear in the Oct. 25 issue of the journal Nature.

- NRL sensor to measure natural airglow in the upper atmosphere
11-06-2006 · EurekAlert!
The second of five Special Sensor Ultraviolet Limb Imager remote sensing instruments, developed by the Naval Research Laboratory, was launched on Nov. 4, 2006 on board the DMSP F-17 satellite. SSULI is the first operational instrument of its kind and provides a new technique for remote sensing of the ionosphere and thermosphere from space. SSULI's measurements will provide scientific data supporting military and civil systems and will assist in predicting atmospheric drag effects on satellites and re-entry vehicles.
