Happily ever after: Scientists arrange protein-nanoparticle marriage

Researchers have discovered a way to easily and effectively fasten proteins to nanoparticles -- essentially an arranged marriage -- by simply mixing them together. The biotechnology is in its infancy. But it already has shown promise for developing an HIV vaccine and as a way to target cancer cells.

Reducing global tobacco use

Although global efforts to cut tobacco use have had some success, more can be done to reduce the number of deaths from smoking, according to a new commentary. More than 170 countries have signed the World Health Organization's (WHO) Framework Convention on Tobacco Control agreement since it was adopted in 2005. However, smoking rates are still high in many low- and middle-income countries compared with Canada and other high-income countries where efforts to curb smoking have been more successful.

Use of radiotherapy after prostate cancer surgery declining, despite evidence of benefit

Despite strong evidence and guidelines supporting its use, post-surgical radiation therapy for prostate cancer patients at risk of recurrence is declining in the United States. This study finds fewer than 10 percent of patients at risk of recurrence received postoperative radiotherapy within six months of surgery in the U.S.

Higher-than-expected pediatric cancer rates identified in two Florida areas

Higher-than-expected rates of pediatric cancers have been identified in the Miami metro area and an area west of the Everglades in a series of five statistical analyses. Comparisons across analyses reveal characteristics of the detected patterns, including the number of cases (two), types of cancer (leukemia or brain/central nervous system cancer) and the racial composition and timing of the cluster west of the Everglades.

Putting the 'education' in 'educational' apps

New apps developed for children come online every day and many of them are marketed or labeled as 'educational' -- but how can we tell which of these thousands of apps will actually help children learn? In a comprehensive new report, a team of researchers integrates research from scientific disciplines like psychological science, linguistics, and neuroscience to provide an evidence-based guide that parents, educators, and app designers alike can use to evaluate the quality of so-called 'educational' apps.

Vampire squid discovery shows how little we know of the deep sea

Among soft-bodied cephalopods, vampire squid live life at a slower pace. At ocean depths from 500 to 3,000 meters, they don't swim so much as float, and they get by with little oxygen while consuming a low-calorie diet of zooplankton and detritus. Now, researchers have found that vampire squid differ from all other living coleoid cephalopods in their reproductive strategy as well.
