Bright light combined with caffeine can improve driving performance and alertness of chronically sleep deprived young drivers, according to a Queensland University of Technology road safety study.

Dr Shamsi Shekari, from QUT's Centre for Accident Research & Road Safety - Queensland (CARRS-Q) presented her findings at the 2016 International Conference on Traffic and Transport Psychology held in Australia this month.

CARRS-Q and Griffith University co-hosted the event which brought together international experts from across the globe to share the latest in road safety research with the aim of reducing road trauma.

Malignant cancers strike certain organs, such as the colon or breast, more often than others. In an Opinion publishing August 9 in Trends in Cancer, researchers propose that this vulnerability in some organs may be due to natural selection. Humans can tolerate tumors in large or paired organs more easily than in small, critical organs, such as the heart, and so the larger organs may have evolved fewer mechanisms to defend against cancerous cells.

People who live in provinces with policies that allow pharmacists to administer influenza vaccines are more likely to be vaccinated, according to a new study in CMAJ (Canadian Medical Association Journal)

"Individuals living in provinces with a policy allowing administration of publicly funded influenza vaccines by pharmacists were more likely to report receipt of a seasonal influenza vaccine in the year before survey participation than those living in jurisdictions without a pharmacy policy," writes Dr. Jeffrey Kwong, Public Health Ontario and Institute for Clinical Evaluative Sciences (ICES), with coauthors.

Teenagers who regularly play online video games tend to improve their school results, according to new research from RMIT University in Melbourne, Australia.

But school students who visit Facebook or chat sites every day are more likely to fall behind in maths, reading and science.

Associate Professor Alberto Posso, from RMIT's School of Economics, Finance and Marketing, investigated the results of testing by the globally recognised Program for International Student Assessment.

PISA tested more than 12,000 Australian 15-year-olds in maths, reading and science, as well as collecting data on the students' online activities.

Posso said video games could help students to apply and sharpen skills learned at school.

HOUSTON - (Aug. 8, 2016) - While binge eating affects about 10 percent of adults in the United States, the neurobiological basis of the disease is unclear. Researchers at the USDA/ARS Children's Nutrition Research Center at Baylor College of Medicine and Texas Children's Hospital found that certain neural circuits have the ability to inhibit binge-like eating behavior in mice. Their report appears today in the journal Biological Psychiatry.

New research from North Carolina State University finds that major volcanic activity on the planet Mercury most likely ended about 3.5 billion years ago. These findings add insight into the geological evolution of Mercury in particular, and what happens when rocky planets cool and contract in general.

There are two types of volcanic activity: effusive and explosive. Explosive volcanism is often a violent event that results in large ash and debris eruptions, such as the Mount Saint Helens eruption in 1980. Effusive volcanism refers to widespread lava flows that slowly pour out over the landscape -- believed to be a key process by which planets form their crusts.
