Gut-directed hypnotherapy delivered by psychologists appears as effective in group or individual sessions, potentially offering a new treatment option for irritable bowel syndrome in primary and secondary care.

Hypnotherapy might help relieve irritable bowel syndrome (IBS) complaints for some patients for as long as 9 months after the end of treatment, according to a randomised controlled trial of 354 adults with IBS in primary and secondary care published in The Lancet Gastroenterology & Hepatology journal.

Children with stomach viruses increasingly are given probiotics to ease symptoms of vomiting and diarrhea. But a major U.S. study led by Washington University School of Medicine in St. Louis shows that a commonly used probiotic is not effective in improving symptoms in young patients with gastroenteritis.

The findings are published Nov. 22 in The New England Journal of Medicine.

Probiotics are a multibillion-dollar industry with marketing claims of being an effective treatment for a multitude of ailments, including diarrhea. However, findings from a new study from the University of Calgary show the popular product has no effect on gastroenteritis, commonly yet erroneously called the stomach flu, in children.

While probiotics are often used to treat acute gastroenteritis (also known as infectious diarrhea) in children, the latest evidence shows no significant differences in outcomes, compared to a placebo. These results come from the large, double-blind, randomized controlled trial conducted at 10 geographically diverse U.S. pediatric emergency departments, including Kenneth & Anne Griffin Emergency Care Center at Ann & Robert H. Lurie Children's Hospital of Chicago. Findings were published in the New England Journal of Medicine.

Scientists at the RDECOM Research Laboratory, the Army's corporate research laboratory (ARL) have found a novel way to safeguard quantum information during transmission, opening the door for more secure and reliable communication for warfighters on the battlefield.

Recent advancements of cutting-edge technologies in lasers and nanophysics, quantum optics and photonics have given researchers the necessary tools to control and manipulate miniature quantum systems, such as individual atoms or photons - the smallest particles of light.

In the era of personalized medicine, scientists are using new genetic and genomic insights to help them determine the best treatment for a given patient. In the case of cancer, the first step toward these treatments is an investigation into how tumor cells behave in an effort to figure out the best drugs to use to attack them.

Research led by a University of Sussex scientist has turned a 156-year-old law of physics on its head in a development which could lead to more efficient recharging of batteries in cars and mobile phones.

WASHINGTON, D.C., November 20, 2018 -- Ever watch aquatic animals jump out of the water and wonder how they manage to do it in such a streamlined and graceful way? A group of researchers who specialize in water entry and exit in nature had the same question and are exploring the specific physical conditions required for animals to successfully leap out of water.

WASHINGTON, D.C., November 20, 2018 -- When professional divers jump from a springboard, their hands are perpendicular to the water, with wrists pointed upward, as they continue toward their plunge at 30 mph.

As they complete what's known as a rip dive, their hands remove water in front of the body, creating a cavity that reduces the initial impact force. The rest of the body, from head to toe, is aligned to shoot through the same cavity created by the hands.

DURHAM, N.C. -- Engineers at Duke University have demonstrated a device that can direct photons of light around sharp corners with virtually no losses due to backscattering, a key property that will be needed if electronics are ever to be replaced with light-based devices.
