Confounding rather than causation may explain association between statin use and lower risk of colorectal cancer

Each year, norovirus causes over 200,000 deaths and a global economic burden of $60 billion. A highly contagious virus that most people will contract 5 times in their lifetime, the most serious outcomes of the disease - hospitalization and death - are far more common among children and the elderly, and in low and middle income countries. In a new PLOS Collection - "The Global Burden of Norovirus & Prospects for Vaccine Development" - global norovirus experts fill critical knowledge gaps and provide key information to further development of a much-needed vaccine.

Insights from the collection

Researchers at the University of North Carolina at Chapel Hill have identified a circuit between two brain regions that controls alcohol binge drinking, offering a more complete picture on what drives a behavior that costs the United States more than $170 billion annually and how it can be treated.

The discovery of brain pathology through autopsy in former National Football League (NFL) players called chronic traumatic encephalopathy (CTE) has raised substantial concern among players, medical professionals, and the general public about the impact of repetitive head trauma. Using sophisticated neuroimaging and analytics, researchers have now identified abnormal areas of low blood flow in living professional football players. These findings, published in the Journal of Alzheimer's Disease, raises the potential for better diagnosis and treatment for persons with football related head trauma.

TORONTO, April 26, 2016 - In 1442, Shinto priests in Japan began keeping records of the freeze dates of a nearby lake, while in 1693 Finnish merchants started recording breakup dates on a local river. Together they create the oldest inland water ice records in human history and mark the first inklings of climate change, says a new report published today out of York University and the University of Wisconsin.

The researchers say the meticulous recordkeeping of these historical "citizen scientists" reveals increasing trends towards later ice-cover formation and earlier spring thaw since the start of the Industrial Revolution.

EAST LANSING, Mich. -- Schools that provide each student with a laptop computer, as well as the appropriate support for both students and teachers, see significant improvement in academic achievement, a new paper indicates.

Michigan State University's Binbin Zheng and colleagues analyzed years of studies on "one-to-one" laptop programs, including Zheng's own research, and found that such programs that take a comprehensive approach were linked to higher test scores in English, math, science and writing, along with other benefits.
