In an article recently published in the Journal of American Medical Association (JAMA), researchers from The Dartmouth Institute for Health Policy and Clinical Practice reviewed medical marketing (the marketing of prescription drugs, disease awareness, laboratory tests and health services to consumers and professionals) over a 20-year period from 1997 through 2016 and found that while it had increased dramatically from about $17.7 billion to $29.9 billion, regulation has not.
In a first-of-its-kind study, researchers discovered journalists can increase media trust by speaking out in defense of their profession, while also doing more fact checking. Contrary to long-established practices in which journalists traditionally ignore attacks, researchers found that the combination of fact checking and defending journalism had positive effects, but fact checking alone did not. This combination increased trust in and use of mainstream news.
The number of middle-aged Australian men who cycle on weekends has doubled in recent years, but the rise of the so-called 'Mamils' (middle aged men in lyrca) is confined to men in more affluent suburbs, says research in today's Medical Journal of Australia.
Even in this digital age, paper is still everywhere. Often, printed materials get used once and are then discarded, creating waste and potentially pollution. Now, scientists report in ACS Applied Materials & Interfaces the development of an easy-to-make 'rewritable' paper that can be drawn or printed on over and over again. The messages can last more than half a year, compared to other rewritable papers whose messages fade after a few days or a few months.
Changes to the media environment have increased polarized voting in America through both addition and subtraction. We argue that the decline of local newspapers has contributed to the nationalization of American politics: as local newspapers close, Americans rely more heavily on available national news or partisan heuristics to make political decisions.
Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new method to 3D print lithium-ion batteries in virtually any shape. They report their results in ACS Applied Energy Materials.
Innuendo alone in news coverage can fuel belief in conspiracy theories, according to a new study.
Neuroscientists at the University of Pennsylvania and the U.S. Army Research Laboratory have forecasted what content will get passed along repeatedly.
Young people who seek out news online on their own, rather than relying on conventional news media or news articles posted on social media, are more likely to participate in political activism and campaigning, according to research by a University of Arizona sociology graduate student.
People are exploring the use of 3D printing for wide-ranging applications, including manufacturing, medical devices, fashion and even food. But one of the most efficient forms of 3D printing suffers from a major drawback: It can only print objects that are gray or black in color. Now, researchers have tweaked the method so it can print in all of the colors of the rainbow. They report their results in the ACS journal Nano Letters.
