A study published today online in The Lancet (March 13, 2009) presented two year data for the bioabsorbable everolimus coronary stent. Commenting on the results, interventional cardiology specialist, Professor Franz Eberli from the University Hospital Zurich (Switzerland) and official spokesperson for the European Society of Cardiology, said:

Platinum is highly desired in jewelry and as a catalyst, but in both cases it is expensive. Now, Penn State researchers have found a way to replace the platinum catalyst in their hydrogen generating microbial electrolysis cells with stainless steel brushes without losing efficiency.

"Stainless steel brush cathodes can produce hydrogen at rates and efficiencies similar to those we have achieved with platinum-catalyzed carbon cloth," says Bruce E. Logan, Kappe professor of environmental engineering.

The devastating effects of excessive alcohol consumption are undisputable, although some data suggest that moderate alcohol consumption may impart some health benefits. For instance, several studies have reported a positive association between alcohol intake and bone mineral density (BMD) in older women. There are fewer studies investigating this relation in men or younger women, and none have considered different classes of alcoholic beverages (beer, wine, and liquor).

When we are faced with a decision, and we're not sure what to do, usually we'll just go with the majority opinion. When do we begin adopting this strategy of "following the crowd"? In a new report in Psychological Science, a journal of the Association for Psychological Science, psychologists Kathleen H. Corriveau, Maria Fusaro, and Paul L. Harris of Harvard University describe experiments suggesting that this tendency starts very early on, around preschool age.

"Fermilab's Tevatron collider typically produces about ten million collisions per second," said DZero co-spokesperson Darien Wood, of Northeastern University. "The Standard Model predicts how many times a year we should expect to see the Higgs boson in our detector, and how often we should see particle signals that can mimic a Higgs. By refining our analysis techniques and by collecting more and more data, the true Higgs signal, if it exists, will sooner or later emerge."

Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum-the parasite that causes malaria in humans.

Hyperbaric treatment for children with autism has reportedly led to improvements in the condition, though previous studies were uncontrolled. Now, a new study published in the open access journal, BMC Pediatrics, is the first controlled trial to report clinical improvements.

Large proportions of European coronary patients are failing to achieve lifestyle, risk factor and therapeutic targets for the prevention of further disease, according to results of the third EUROASPIRE survey.(1) The survey, conducted on behalf of the European Society of Cardiology (ESC), analysed medical records and interviewed almost 9000 patients with coronary heart disease in 22 countries of Europe.

DURHAM, NC – A new drug derived from magnolia trees appears to be able to uncouple two important functions of thrombin in blood clot formation and may offer a way to better control the potentially dangerous complications of bleeding and clot formation during procedures to open blocked coronary arteries, say researchers at the Duke Clinical Research Institute (DCRI).

GAINESVILLE, Fla. --- A new University of Florida study could help resolve a long-standing debate in shark paleontology: From which line of species did the modern great white shark evolve?

March 12, 2009 - (BRONX, NY) - Women with certain gene variations appear to be protected against cervical cancer, according to a study led by scientists at Albert Einstein College of Medicine of Yeshiva University and reported in Clinical Cancer Research. Knowing whether or not women have these genetic variants could help physicians to better tailor treatment strategies.

Researchers have developed a new mouse model that allows them to replicate normal pigment cells at the earliest stages of conversion to malignant skin cancer in humans. After testing the mouse with a combination of two drug therapies, the team found the treatment caused a statistically significant regression in cancer cell development.

HOUSTON -- (March 12, 2009) -- An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors.

March 12, 2009 -- Exposure to critical incidents, workplace discrimination, lack of cooperation among coworkers, and job dissatisfaction correlated significantly with perceived work stress among urban police officers, according to a study by researchers at Columbia University's Mailman School of Public Health. Work stress was significantly associated with adverse outcomes, including depression and intimate partner abuse.
