Applications range from protective coating to sterilize hospital surfaces and medical equipment or as an injection to more effectively treat patients

SAN JOSE, Calif. – 24 Jan 2013: Researchers from IBM and the Institute of Bioengineering and Nanotechnology revealed today an antimicrobial hydrogel that can break through diseased biofilms and completely eradicate drug-resistant bacteria upon contact. The synthetic hydrogel, which forms spontaneously when heated to body temperature, is the first-ever to be biodegradable, biocompatible and non-toxic, making it an ideal tool to combat serious health hazards facing hospital workers, visitors and patients.

Traditionally used for disinfecting various surfaces, antimicrobials can be found in traditional household items like alcohol and bleach. However, moving from countertops to treating drug resistant skin infections or infectious diseases in the body are proving to be more challenging as conventional antibiotics become less effective and many household surface disinfectants are not suitable for biological applications.

Costly Breast Cancer Screenings Don’t Add up to Better Outcomes

Even though Medicare spends over $1 billion per year on breast cancer screenings such as a mammography, there is no evidence that higher spending benefits older women, researchers at Yale School of Medicine found in a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

Led by Dr. Cary Gross, associate professor of internal medicine at Yale School of Medicine and director of the Cancer Outcomes, Public Policy, and Effectiveness Research (COPPER) Center at Yale, the study sought to provide a comprehensive understanding of breast cancer expenditures that incorporate the cost of screening and associated work-up, as well as treatment. They assessed overall national costs, as well as variation in costs across geographic regions. (more…)

For Devin Naar, the Sephardic Studies Initiative is not just a valuable historical archive; it has also been a personal journey revealing an untold family story from the years of the Third Reich.

Naar’s part of the story began about 10 years ago, when as an undergraduate at Washington University he grew interested in the history of Turkey and Greece, which for centuries until World War I was part of the Ottoman Empire. His family comes from Salonica, a port city in Northern Greece. (more…)

ANN ARBOR — Playing violent video games about terrorism strengthens negative stereotypes about Arabs, even when Arabs are not portrayed in the games.

That is one of the findings of an innovative new study in the January issue of Psychology of Violence, a peer-reviewed journal published by the American Psychological Association. (more…)

Born to Lead? Leadership Can be an Inherited Trait, Study Finds

Genetic differences are significantly associated with the likelihood that people take on managerial responsibilities, according to new research from UCL (University College London).

The study, published online in Leadership Quarterly, is the first to identify a specific DNA sequence associated with the tendency for individuals to occupy a leadership position. Using a large twin sample, the international research team, which included academics from Harvard, NYU, and the University of California, estimate that a quarter of the observed variation in leadership behaviour between individuals can be explained by genes passed down from their parents.

Recognizing Psychological Common Ground Could Ease Tensions Among Those with Different Religious Beliefs, says MU Psychologist

COLUMBIA, Mo. — Understanding how thoughts of mortality influence individuals’ beliefs sheds light on the commonalities among different groups’ motivations and could help ease tensions between opposing viewpoints, according to University of Missouri experiments that tested the relationship between awareness of death and belief in a higher power. The study found that thoughts of death increased atheists, Christians, Muslims and agnostics conviction in their own world views. For example, contrary to the wartime aphorism that there are no atheists in foxholes, thoughts of death did not cause atheists to express belief in a deity.

“Our study suggests that atheists’ and religious believers’ world views have the same practical goal,” said Kenneth Vail, lead author and doctoral student in psychological science in MU’s College of Arts and Science. “Both groups seek a coherent world view to manage the fear of death and link themselves to a greater and immortal entity, such as a supreme being, scientific progress or a nation. If people were more aware of this psychological similarity, perhaps there might be more understanding and less conflict among groups with different beliefs.” (more…)

PASADENA, Calif. — The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute of Technology in Pasadena.

Measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy. (more…)

WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.

The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)
