New research has determined that patients in the U.S. with hepatitis C virus (HCV) are twice as likely to not have health insurance coverage compared with those without the disease. In fact researchers found only a third of HCV infected Americans have access to antiviral therapy; the remaining are either uninsured or not candidates for therapy due to treatment contraindications. Details of this study are published in the March issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD).

February 24, 2011 – T-cell receptor diversity in blood samples from healthy individuals has been extensively cataloged for the first time in a study published online today in Genome Research (www.genome.org), setting the stage for a better understanding of infectious disease, cancer, and immune system disorders.

DURHAM, N.C. – High-resolution images from a laser-based tool developed at Duke University could help doctors better diagnose melanoma, the deadliest form of skin cancer, while potentially saving thousands of lives and millions of dollars in unnecessary healthcare costs each year.

The tool probes skin cells using two lasers to pump small amounts of energy, less than that of a laser pointer, into a suspicious mole. Scientists analyze the way the energy redistributes in the skin cells to pinpoint the microscopic locations of different skin pigments.

BOULDER, Colo.—Physicists at the NationalInstitute of Standards and Technology(NIST) have for the first time coaxed twoatoms in separate locations to take turnsjiggling back and forth while swapping thesmallest measurable units of energy. Bydirectly linking the motions of two physicallyseparated atoms, the technique has thepotential to simplify information processing infuture quantum computers and simulations.

The Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennae, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers. The researchers have published their work in the scientific journal Nature.

The perception of negative stereotyping, particularly in the areas of financial services and automobile sales and service, can cause consumers to fear being duped and forgo their purchases, according to new research by University of Minnesota associate professor Kathleen D. Vohs.

Whether on a battlefield, in a factory or at a rock concert, noise-induced hearing loss is one of the most common hazards people face.

Researchers at Washington University School of Medicine in St. Louis have identified a low-dose, two-drug cocktail that reduces hearing loss in mice when given before they are exposed to loud noise. The drugs, already FDA-approved for other conditions, also treat hearing loss after noise exposure.

While both drugs are known to protect hearing on their own, this is the first study to test the two in combination.

Mention solar energy, and most people think "squeaky clean, pollution-free." The reality of making solar panels with existing technology, however, is much different, involving use of potentially toxic substances and lots of energy. That could change, according to an article in the current edition of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.

Scientists are reporting development of an advanced lithium-ion battery that is ideal for powering the electric vehicles now making their way into dealer showrooms. The new battery can store large amounts of energy in a small space and has a high rate capacity, meaning it can provide current even in extreme temperatures. A report on this innovation appears in ACS' Journal of the American Chemical Society.

Millions of people dealing with health issues have found comfort sharing their stories online with others who experience similar ailments, but research on their clinical effectiveness is limited, and findings are mixed. Among people with mental illnesses, the results are sparser, even though research has shown that this group prefers online peer support groups over face-to-face support groups.

Troy, N.Y. – In the restaurant of the future, you will always enjoy the perfect meal with that full-bodied 2006 cabernet sauvignon, you will always know your dinner companions' favorite merlot, and you will be able to check if the sommelier's cellar contains your favorite pinot grigio before you even check your coat. These feats of classic cuisine will come to the modern dinner through the power of Semantic Web technology.

Pukas Surf (the leading manufacturer and distributor of high-performance surfboards in Europe) and Tecnalia Research & Innovation have presented their research work into the mechanical behaviour of surfboards.

Madison, WI FEBRUARY 10, 2011 – Finding employment can be a daunting task. Millions of college graduates, new to the professional work force, face this challenge every year after receiving their degrees. Many have sacrificed and toiled for perfect grades, worked at internships to prepare for careers, and filled their schedules with university affiliated clubs and activities. The belief that these attributes will enhance a resume and impress an employer is widespread, but does it really reflect what employers seek in a new hire?

CHICAGO --- Paid caregivers make it possible for seniors to remain living in their homes. The problem, according to a new Northwestern Medicine study, is that more than one-third of caregivers had difficulty reading and understanding health-related information and directions. Sixty percent made errors when sorting medications into pillboxes.

The study will be published in the Journal of General Internal Medicine. It has been published online.
