A new screening guideline from the Canadian Task Force on Preventive Health Care (CTFPHC) for abdominal aortic aneurysms (AAAs), which cause approximately 1244 deaths every year in Canada, recommends one-time ultrasonography screening for men aged 65 to 80 years.

Milan, Italy: Two new studies presented at the European Respiratory Society International Congress highlight the risks associated with using e-cigarettes, especially for those who also smoke conventional cigarettes.

One study examined 122 of the most commonly sold e-cigarette liquids in nine European countries and found that all contained at least one substance classified as a health risk.

Conventional electron accelerators have become an indispensable tool in modern research. The extremely bright radiation generated by synchrotrons, or free electron lasers, provides us with unique insights into matter at the atomic level. But even the smallest versions of these super microscopes are the size of a soccer field. Laser plasma acceleration could offer an alternative: with a much smaller footprint and much higher peak currents it could be the basis for the next generation of compact light sources.

ANN ARBOR, MI - The dental health of middle-aged Americans faces a lot of problems right now, and an uncertain future to come, according to new results from the University of Michigan National Poll on Healthy Aging.

LOWELL, Mass. - Three-quarters of fans say head injuries in football are a major problem and another six in 10 are worried about off-field violence involving players. Despite that, football remains America's favorite professional sport, according to results of a UMass Lowell-Washington Post poll released today.

Annapolis, MD; September 6, 2017--As an entomologist with an artistic flair, Carly Tribull, Ph.D., frequently uses a novel approach for conveying science to non-academic audiences: comics.

LAWRENCE -- A paper appearing recently in the peer-reviewed journal Comprehensive Psychiatry details a "radical" new method for diagnosing eating disorders that predicts 68 percent of people's problems in psychological and social functioning due to eating-disorder features.

By contrast, the method of identifying eating disorders outlined by the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-5) traditionally used by clinicians predicts slightly less than 10 percent of impairment in psychological and social functioning.

A neutron beam was produced at the China Spallation Neutron Source (CSNS) for the first time on August 28. The achievement is a milestone for the CSNS project as it marks the completion of main construction and the start of the test operation phase.

The national CSNS facility, located in Dongguan, Guangdong Province, should be fully completed and open to domestic and international users by 2018, as scheduled.

A better understanding of how a key chemical messenger acts in the brain could lead to a radical shift in psychiatric care, according to a new research paper.

Serotonin is a neurotransmitter which helps brain cells communicate with one another, playing important roles in stabilising mood and regulating stress.

Despite its importance, current models to explain serotonin's function in the brain remain incomplete.

Researchers at the RIKEN Brain Science Institute in Japan have discovered a process through which changes in nutrition during early mouse pregnancy lead to offspring that develop schizophrenic-like symptoms as adults. Published in Translational Psychiatry, the study shows how deprivation of two polyunsaturated fatty acids during early gestation can have long lasting effects on offspring through specific epigenetic changes in gene expression.
