WASHINGTON -- Compared to other medical settings, emergency patients who are prescribed opioids for the first time in the emergency department are less likely to become long-term users and more likely to be prescribed these powerful painkillers in accordance with The Centers for Disease Control and Prevention (CDC) guidelines.

Pediatric researchers investigating the childhood cancer neuroblastoma have identified common gene variants that raise the risk of an aggressive form of that disease. The discovery may assist doctors in better diagnosing subtypes of neuroblastoma.

CORAL GABLES, Fla. (Sept.25, 2017) Children's mental state plays an important factor in their developmental growth. After recent storms devastated parts of the U.S. - Hurricane Harvey in Texas, Hurricane Irma in Florida and the Caribbean and Hurricane Maria in Puerto Rico -- all contributing to massive evacuations of children and families, which children need more attention or support services in the aftermath of these storms and the related stressors that come with surviving and witnessing the destructive power of a Category 4 or 5 hurricane?

DALLAS - Sept. 25, 2017 - Do you really need that MRI?

Your doctor may order an MRI based on factors other than your actual medical need for imaging, researchers in UT Southwestern's Center for Patient-Centered Outcomes Research found. Their study in JAMA Internal Medicine showed that a physician's prior image-ordering habits, as well as ownership of the equipment, were strong indicators of unnecessary imaging orders.

Researchers at the University of Delaware are looking into what causes that gut feeling in livestock animals such as cows and chickens.

Ryan Arsenault, assistant professor in the Department of Animal and Food Sciences in UD's College of Agriculture and Natural Resources (CANR), arrived at UD in 2015 and since that time, he has worked to set up a lab looking specifically at the gut health of production livestock animals.

Toronto - In the era of a renewed spotlight on offshore tax havens, a new study suggests U.S. tax reporting rules still make it easy for corporations to quietly shift and shelter profits in low-tax jurisdictions, avoiding public scrutiny.

After four years of lab testing and complex neuro-decoding, a research team led by UNLV psychology professor James Hyman has struck a major breakthrough that could open the floodgates for research into the anterior cingulate cortex, or ACC, and how human brains learn.

Researchers have observed and characterized a weather process that was not previously known to occur in Antarctica's coastal regions. It turns out that the katabatic winds that blow from the interior to the margins of the continent reduce the amount of precipitation (mainly snowfall) -- which is a key factor in the formation of the ice cap. By forming a very dry layer of air in the first kilometer or so of atmosphere, the winds turn the falling snowflakes during their fall directly from their solid state into water vapor in a process known as sublimation.

Freshwater planarians, found around the world and commonly known as "flatworms," are famous for their regenerative prowess. Through a process called "fission," planarians can reproduce asexually by simply tearing themselves into two pieces -- a head and a tail -- which then go on to form two new worms within about a week.

Tropical Storm Pilar formed near the southwestern coast of Mexico on Saturday, Sept. 23 and continued hugging the coast when NASA's Terra and Aqua satellites passed overhead. Pilar weakened to a tropical depression during the late morning on Sept. 25.
