Today, the Consortium for Advanced Simulation of Light Water Reactors (CASL) announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor. CASL is modeling nuclear reactors on supercomputers to help researchers better understand reactor performance with much higher reliability than previously available methods, with the goal of ultimately increasing power output, extending reactor life, and reducing waste.

A new study of HIV infection by UC San Francisco researchers points to changes in intestinal bacteria as a possible explanation for why successfully treated HIV patients nonetheless prematurely experience life-shortening chronic diseases.
These changes in gut bacteria may perpetuate inflammation initially triggered by the body's immune response to HIV, according to the study, reported online July 10 in the journal Science Translational Medicine.
AURORA, Colo. (July 10, 2013) – Rates of angiography and percutaneous coronary interventions were significantly lower among Medicare Advantage beneficiaries when compared to those covered by Medicare fee-for-service, according to a study by a University of Colorado School of Medicine physician published in the July 10 issue of JAMA.
The study, which included nearly 6 million Medicare Advantage and Medicare fee-for-service beneficiaries from 12 states, also found that geographic variation in procedure rates was substantial for both payment types.
In the 2012 presidential election, seven out of 10 Latino immigrants voted for President Obama. As news pundits dissected the defeat of Mitt Romney, they dismissed the Latino vote as unattainable for the Republican Party.
But University of Nebraska-Lincoln political scientist Sergio Wals says that's not necessarily the case. In a new study published in the journal Electoral Studies, Wals found that Mexican immigrants who are more politically invested are center or center-right in their political ideologies.
Today's smartphones allow for increased opportunities for activities traditionally defined as sedentary behaviors, such as surfing the internet, emailing and playing video games. However, researchers Jacob Barkley and Andrew Lepp, faculty members in the College of Education, Health and Human Services at Kent State University, linked high cell phone use to poor fitness in college students.
WASHINGTON — Emergency physicians and other emergency department staff were fairly accurate in assessing which patients were drug-seekers in the emergency department, changing their prescribing plans for less than 10 percent of patients after consulting an objective computerized state prescription drug monitoring program (PDMP). The analysis of emergency providers' prescribing patterns and clinical factors associated with suspecting drug-seeking in the ER were published online yesterday in Annals of Emergency Medicine ("Clinician Impression vs.
Alexandria, VA -- Scientists have recently confirmed the existence of an impact crater buried below the town of Decorah, Iowa. Scientists first discovered what they thought resembled a crater in 2008, but now it has been corroborated by an airborne geophysical survey and hydrology surveys. Scientists estimate the diameter of the crater at 5.5 kilometers wide, nearly five times the size of the Barringer Meteor Crater in Arizona.
Reston, Va. (July 10, 2013) – A new treatment option for patients with relapsing follicular, mantle cell and other indolent B-cell lymphomas has been determined safe and feasible by researchers exploring the potential of a low energy beta-emitter radiopharmaceutical. According to data published in the July issue of The Journal of Nuclear Medicine, the use of 177Lu-DOTA-rituximab as a radioimmunotherapy results in a high rate of tumor response while using less radiation than current therapies.
The economic crisis has put measurable pressure on birthrates in Europe over the last decade. On average, the more the unemployment rose, the greater the decrease in fertility compared to the number of children per women expected without the crisis. This is the result of a new study performed by the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany.
Hamilton, ON (July 9, 2013) - Three waves of the deadliest influenza pandemic in history, known as the Spanish flu, hit England and Wales in 1918, just as World War 1 was coming to an end.
Why flu arrives in multiple waves like this is the focus of a study by McMaster University researchers who discovered three contributing factors: the closing and opening of schools, temperature changes and – most importantly – changes in human behavior.
Implementing smoke-free laws and increased tobacco taxes in India would yield substantial and rapid health benefits by averting future cardiovascular disease (CVD) deaths, according to a new study published this week in PLOS Medicine. The results of this study, conducted by Sanjay Basu and colleagues of Stanford University, USA, suggest that specific tobacco control strategies would be more effective than others for the reduction of CVD deaths over the next decade in India and possibly in other low- and middle-income countries.
New interventional cardiac catheterization services offered by U.S. hospitals generally duplicate existing programs and do not help patients gain access to timely emergency cardiac care, according to a new study.
Examining new cardiac catheterization programs nationally from 2004 to 2008, researchers found the programs were most likely to be introduced in areas that had existing services, near populations that had higher rates of private health insurance and in states where there is little oversight of hospitals.
In a study that included nearly 6 million Medicare Advantage and Medicare fee-for-service beneficiaries from 12 states, rates of angiography and percutaneous coronary interventions were significantly lower among Medicare Advantage beneficiaries and geographic variation in procedure rates was substantial for both payment types, according to a study in the July 10 issue of JAMA.
Research examines differences in rates of cardiac catheterization between New York State and Ontario
The increased use of cardiac catheterization in New York relative to Ontario appears related to selecting more patients at low risk of obstructive coronary artery disease, with the subsequent diagnostic yield (i.e., the proportion of tested patients in whom disease was diagnosed) of this procedure in New York significantly lower than in Ontario, according to a study in the July 10 issue of JAMA.
Dual antiplatelet therapy following coronary stent implantation is associated with improved outcomes
Emmanouil S. Brilakis, M.D., Ph.D., of the VA North Texas Health Care System and University of Texas Southwestern Medical Center at Dallas, and colleagues conducted a review of medical literature regarding optimal medical therapy after percutaneous coronary intervention (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries). The researchers identified 91 studies for inclusion in the review.
