Human mortality and survival may have improved in the generations following the Black Death, according to results published May 7, 2014, in the open access journal PLOS ONE by Sharon DeWitte from University of South Carolina.

For years, scientists have had an itch they couldn't scratch. Even with the best microscopes and spectrometers, it's been difficult to study and identify molecules at the so-called mesoscale, a region of matter that ranges from 10 to 1000 nanometers in size. Now, with the help of broadband infrared light from the Advanced Light Source (ALS) synchrotron at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), researchers have developed a broadband imaging technique that looks inside this realm with unprecedented sensitivity and range.

When you get sick, your physician may take a sample of your blood, send it to the lab and wait for results. In the near future, however, doctors may be able to run those tests almost instantly on a piece of plastic about the size of credit card.

Leesburg, VA, May 5, 2014—Dose-tracking software provides effective and easy monitoring of radiation dose exposure in a busy academic practice, according to research conducted at Massachusetts General Hospital.

For commonly ordered abdominal CT exams, iterative reconstruction techniques enabled approximately 50 percent radiation dose reduction compared to the national averages reported in the Dose Index Registry*.

BUFFALO, N.Y. — Companies should use existing brand names and add new, sub-brand names to maximize revenue when introducing new products to market, according to a new study from the University at Buffalo School of Management.

Forthcoming in Management Science, the study notes a proliferation of new products in the consumer packaged-goods market each year. For example, U.S. manufacturers introduced more than 150,000 new products in 2010 alone. Of these, more than 90 percent were extensions of existing brand-name products.

Physicists are now designing novel materials with physical properties tailored to meet specific energy consumption needs. Before these so-called materials-by-design can be applied, it is essential to understand their characteristics, such as heat flow. Now, a team of Italian physicists has developed a predictive theoretical model for heat flux in these materials, using atom-scale calculations. The research, carried out by Claudio Melis and colleagues from the University of Cagliary, Italy, is published in EPJ B.

The world first review explored interpersonal racism perpetrated by healthcare providers, a key driver of racial disparities in health. Interpersonal racism refers to racist interactions between individuals, rather than internalised or systemic or institutional racism.

Researchers Ms Mandy Truong and Dr Naomi Priest from the University of Melbourne and Professor Yin Paradies from Deakin University, reviewed 37 studies published between 1995 and 2012 of racism among healthcare providers.

Earlier this year, bloggers scored a high-profile victory in their campaign against a common bread ingredient — also used in yoga mats and other plastics — when Subway announced it was dropping the substance from its dough recipe. The case highlights the powerful influence of online campaigns, and how they are changing the food industry, according to an article in Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society.

Yellow fever, an acute viral disease, is estimated to have been responsible for 78,000 deaths in Africa in 2013 according to new research published in PLOS Medicine this week. The research by Neil Ferguson from Imperial College London, UK and colleagues from Imperial College, WHO and other institutions also estimates that recent mass vaccination campaigns against yellow fever have led to a 27% decrease in the burden of yellow fever across Africa in 2013.

Montreal, May 6, 2014 — A sexy wood elf with pointy ears. A hulking ogre with blue skin. An intimidating heroine with a buxom breastplate. When it comes to computer games, players can choose to be anyone or anything. But gamers don't always mask their true identities with online avatars.

All industrial nations need large volumes of oil which is normally delivered by ocean-going tankers or via inland waterways to its destination. The most environmentally-friendly way of cleaning up nature after an oil spill accident is to absorb and recover the floating film of oil. The Empa researchers Tanja Zimmermann and Philippe Tingaut, in collaboration with Gilles Sèbe from the University of Bordeaux, have now succeeded in developing a highly absorbent material which separates the oil film from the water and can then be easily recovered, "silylated" nanocellulose sponge.

Investigators have found social media to be an effective tool for researching the clinical presentation and treatment of a mass casualty event of nerve agent poisoning, according to the article in Annals of Internal Medicine.

Organophosphate (OP) nerve agents are some of the most lethal weapons of chemical warfare. In 2013 sarin gas, an OP agent, was used in Ghouta, Damascus, killing 1,400 civilians and severely affecting thousands more.

PHILADELPHIA, PA, May 6, 2014 – Weekly consumption of sports drinks and energy drinks among adolescents is significantly associated with higher consumption of other sugar-sweetened beverages, cigarette smoking, and screen media use, according to a study conducted by researchers from the University of Minnesota and Duke University.

HOUSTON – (May 5, 2014) – Reform of energy subsidies in oil-exporting countries can reduce carbon emissions and add years to oil exports, according to a new paper from Rice University's Baker Institute for Public Policy.

PROVIDENCE, R.I. – A new study from the Bradley Hasbro Children's Research Center has found that family-based cognitive behavioral therapy (CBT) is beneficial to young children between the ages of five and eight with Obsessive-Compulsive Disorder (OCD). The study, now published online in JAMA Psychiatry, found developmentally sensitive family-based CBT that included exposure/response prevention (EX/RP) was more effective in reducing OCD symptoms and functional impairment in this age group than a similarly structured relaxation program.
