A study published in Science magazine contains new population assessments for thousands of fisheries around the globe, providing insight on the health of data-poor fisheries that account for more than 80 percent of the world's catch. The research confirms suspicions that these fisheries are in decline, but it also highlights hope for the future: most of these fisheries have not yet collapsed. If we act quickly to prevent overfishing and allow depleted stocks to recover to sustainable levels, they could provide more seafood over the long-term.

Santa Barbara – A study published in Science magazine and co-authored by Bren School Sustainable Fisheries Group (SFG) researchers and their colleagues confirms suspicions that thousands of "data-poor" fisheries, representing some 80 percent of the world's fisheries, are in decline but could recover with proper management.
At least when it comes to female politicians, perhaps you can judge a book by its cover, suggest two UCLA researchers who looked at facial features and political stances in the U.S. House of Representatives.
"Female politicians with stereotypically feminine facial features are more likely to be Republican than Democrat, and the correlation increases the more conservative the lawmaker's voting record," said lead author Colleen M. Carpinella, a UCLA graduate student in psychology.
Incarcerated patients with chronic hepatitis C virus (HCV) infection are just as likely to respond to treatment for the disease as patients in the community, according to findings published in the October issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases. The study from the University of Wisconsin School of Medicine and Public Health (SMPH) in Madison found that HCV patients in prison were just as likely to achieve a sustained viral response (SVR) as non-incarcerated patients.
WASHINGTON, D.C. — With the U.S. economy vulnerable to weather events costing billions of dollars, an expert panel today asked Congress to create the first U.S. Weather Commission. The commission would provide guidance to policymakers on leveraging weather expertise across government and the private sector to better protect lives and businesses.
Top box office films last year showed more onscreen smoking than the prior year, reversing five years of steady progress in reducing tobacco imagery in movies, according to a new UCSF study.
Moreover, many of the top-grossing films of 2011 with significant amounts of smoking targeted a young audience, among them the PG-rated cartoon Rango and X-Men: First Class." The more smoking young people see in movies, the more likely they are to start smoking, the U.S. Surgeon General has reported.
African-American youth ages 12-20 are seeing more advertisements for alcohol in magazines and on TV compared with all youth ages 12-20, according to a new report from the Center on Alcohol Marketing and Youth (CAMY) at the Johns Hopkins Bloomberg School of Public Health. The report is available on CAMY's website, www.camy.org.
Similar characteristics have not been observed in other constructions of the Bronze Age, with three-metre thick walls, square towers originally measuring up to seven metres, a monumental entrance and an ogival arched postern gate; a fully conserved architectural element unique in Europe in that period.
The wall protected a city measuring 4 hectares located on top of a hill. With architectural elements reminiscent of people with Eastern styled military skills, its model is typical of ancient civilisations of the Mediterranean, such as the second city of Troy.
Scientists use simulations to test the limits of their object of study—in this case thin films of polymers—to extremes of scale. In a study¹ about to be published in EPJ E, Nava Schulmann, a researcher at Strasbourg University, France, and colleagues use a well-known model capable of providing information on heat and mechanical energy exchange between these polymer chains. They found that polymer blends confined to ultrathin two-dimensional films displayed enhanced compatibility.
Chicago (September 27, 2012)—New comprehensive guidelines for the pre- operative care of the nation's elderly patients have been issued by the American College of Surgeons (ACS) and the American Geriatrics Society (AGS). The joint guidelines—published in the October issue of the Journal of the American College of Surgeons—apply to every patient who is 65 years and older as defined by Medicare regulations.
WASHINGTON – Using a newly discovered cell technology, Georgetown University Medical Center researchers were able to identify an effective therapy for a patient with a rare type of lung tumor. The single case study, reported in the September 27 issue of New England Journal of Medicine, provides a snapshot of the new technology's promising potential; however, researchers strongly caution that it could be years before validation studies are completed and regulatory approval received for its broader use.
Results from an observational study evaluating a new anti-TB drug have found that the treatment can improve outcomes and reduce mortality among patients with both MDR-TB and XDR-TB.
The research, published online ahead of print today (27 September 2012) in the European Respiratory Journal, suggests a drug called delamanid could have a public health benefit for MDR-TB and also for XDR-TB, as few effective treatment options are currently available.
UNIVERSITY PARK, Pa. -- Coating a bone graft with an inorganic compound found in bones and teeth may significantly increase the likelihood of a successful implant, according to Penn State researchers.
Natural bone grafts need to be sterilized and processed with chemicals and radiation before implantation into the body to ensure that disease is not transmitted by the graft. Human bones have a rough surface. However, once a graft is sterilized the surface changes and is not optimal for stimulating bone formation in the body.
UNIVERSITY PARK, Pa. -- When nurses feel safe admitting to their supervisors that they've made a mistake regarding a patient, they are more likely to report the error, which ultimately leads to a stronger commitment to safe practices and a reduction in the error rate, according to an international team of researchers. In addition, when nurse leaders' safety actions mirror their spoken words -- when they practice what they preach -- unit nurses do not feel caught between adhering to safety protocols and speaking up about mistakes against protocols.
UNIVERSITY PARK, Pa. -- People are more likely to trust health messages tweeted by doctors who have a lot of followers, but not the messages they retweet, according to researchers.
