Crash Risk: Study Highlights Lifestyle, Occupational Factors That May Put Truck Drivers in Danger

SALT LAKE CITY - Truck drivers who are frequently fatigued after work, use cell phones while driving, or have an elevated pulse pressure – a potential predictor of cardiovascular disease - may be at increased risk for getting into truck accidents, according to a study by the Rocky Mountain Center for Occupational and Environmental Health (RMCOEH) at the University of Utah School of Medicine and published in the Journal of Occupational and Environmental Medicine (JOEM). The findings suggest that characteristics of the profession may put truck drivers at risk.

The iconic sugar maple, one of the most economically and ecologically important trees in the eastern United States and Canada, shows signs of being in a significant decline, according to research results published today (Oct. 21, 2015) in the open-access journal “Ecosphere.”

Provision of Mental Health Care Services – Not Just Screenings – Critically Important for Children with Food Allergies

Mental health screenings – for anxiety, for example – is routinely recommended by various pediatric societies. Now, a study from Mount Sinai questions the wisdom of such guidelines. Findings from a large-scale screening effort in a pediatric food allergy clinic, made by researchers at the Icahn School of Medicine at Mount Sinai and led by Eyal Shemesh, MD, were first published online in The Journal of Pediatrics.

Scientists Find Link between Comet and Asteroid Showers & Mass Extinctions

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published in Monthly Notices of the Royal Astronomical Society.

New ‘Geospeedometer’ Confirms Super-Eruptions Have Short Fuses

A new "geospeedometer" that can measure the amount of time between the formation of an explosive magma melt and an eruption confirms that the process took less than 500 years in several ancient super-eruptions.

Two Lefts Make It Right: Cardiac Experts Find Novel Approach to Treat Heart Failure

A teenage girl faced with sudden rapid heart deterioration, a man in the prime years of his life suffering from debilitating heart failure and a former NFL athlete crippled by end-stage heart failure were all successfully treated with a surgical approach pioneered by cardiac experts at University of California, San Diego School of Medicine.

A new study, led by scientists at The Scripps Research Institute, the Veterans Affairs San Diego Healthcare System and University of California San Diego School of Medicine shows that increasing a crucial membrane protein in nerve cells within the brain can improve learning and memory in aged mice.

Stimulating Specific Brain Area Could Help Defrost Arms Frozen by Stroke

Little can be done to help the hundreds of thousands of people whose severe strokes have left them with one arm stuck close to the sides of their bodies like a broken wing. A 30-patient study by Washington researchers, however, has found that magnetically stimulating a specific part of their brains can affect arm movements — raising hope that, in the future, a short course of therapy targeting this area could help to free the arm and restore some use of the stroke-affected limb.

Building Immune System Memory

A study led by the University of Utah School of Medicine has identified molecular mechanisms that control an immune cell’s ability to remember. They found that in helper T cells, the proteins Oct1 and OCA-B work together to put immune response genes on standby so that they are easily activated when the body is re-exposed to a pathogen. The research, which could inform strategies for developing better vaccines, was performed in collaboration with scientists from The Broad Institute and University of Michigan, and published in The Journal of Experimental Medicine.
