Washington University School of Medicine in St. Louis and Barnes-Jewish West County Hospital are offering a newly approved, nonsurgical therapy to help people lose weight. Shelby Sullivan, MD, holding models of the two systems being used, said the therapy involves placing special balloons into the stomach and inflating them to give patients the feeling of being full after eating small meals.

The Moon was never a fully homogenized body like Earth, analysis of Moon rocks made by the Chinese rover, Yutu, suggests. The basalts the rover examined are a new type, chemically different from those retrieved by the Apollo and Luna missions 40 years ago.

Curious seismologists who looked at the recordings made by a seismic station four miles away from the “cook-off” of an ammunition holding area in Iraq in 2006 found they could distinguish, mortars, rockets, improvised explosive devices, helicopters and drones. Seismology is increasingly being used for investigative purposes, they said, not just to detect earthquakes.

In a new analysis, researchers at the School of Medicine have shed light on the hereditary elements across 12 cancer types — showing a surprising inherited component to stomach cancer and providing some needed clarity on the consequences of certain types of mutations in well-known breast cancer susceptibility genes BRCA1 and BRCA2.

Wishing family and friends a “Happy New Year” is all well and fine, but if you’re serious about spreading cheer in the New Year, consider passing along more specific advice from a psychologist who studies the science of happiness at Washington University in St. Louis.

There is renewed interest by some Missouri groups for a proposed 23-cent-per-pack raise to Missouri’s tobacco tax, which is the nation’s lowest. While any raise in tobacco prices is one of the most effective ways to reduce and prevent smoking, the modest tax raise does not go far enough, says a tobacco control expert at Washington University in St. Louis. ​

During a five-year period ending in 2013, nearly 400 children ages 16 or under were taken to one of two hospital emergency rooms in St. Louis for gun-related injuries, according to a study led by Martin S. Keller, MD, at Washington University School of Medicine in St. Louis. Of those children, 20 later died. Analyzing such cases can help identify risk factors and stem gun-related injuries, researchers believe.

The brains of children who suffer clinical depression as preschoolers develop abnormally, compared with the brains of preschoolers unaffected by the disorder, according to university researchers. Their gray matter is lower in volume and thinner in the cortex, a part of the brain important in the processing of emotions.

Biologists have long thought that body size is correlated with temperature zone: larger animals live in colder regions and smaller ones in warmer ones. Newly compiled physiological data allowed this rule to be put to the test. Animals adapt by coordinated changes in their metabolic rates and “insulation.” Body size plays only a minor role.

​As the new year approaches, many plan to make self-improvement resolutions. New research led by Hengchen Dai, PhD, assistant professor at Olin Business School at Washington University in St. Louis, shows extra motivation is all in the timing, and desire to get away from one’s past, imperfect self.
