In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals […]

Gut microbiome may influence how cancer patients respond to oral therapies, study suggests
A new study from Lawson Health Research Institute and Western University illustrates how the gut microbiome interacts with an oral medication in prostate cancer patients, suggesting bacteria in the gut play a role in treatment outcomes. The findings, published in Nature Communications, highlight how the drug abiraterone acetate is metabolized by bacteria in the gut […]
Romantic partnerships mitigate influence of genetic predisposition to alcohol consumption
People with a genetic predisposition to risky alcohol behavior are less likely to drink frequently, become intoxicated often, or suffer from alcohol dependence symptoms if they are in a romantic relationship, according to a new study led by a Virginia Commonwealth University researcher. “We found that the effect of genetic risk for alcohol use was […]
Brain’s cerebellum found to influence addictive and social behavior
In a study published online today in the journal Science, researchers at Albert Einstein College of Medicine, part of Montefiore, prove for the first time that the brain’s cerebellum—long thought to be mainly involved in coordinating movement—helps control the brain’s reward circuitry. The surprising finding indicates that the cerebellum plays a major role in reward […]
Early career choices appear to influence personality, study finds
In the state of Baden-Wurttemberg, Germany, 16-year-old students in middle-track schools decide whether to stay in school to pursue an academic career or enroll in a vocational training program.

Immune cells in the brain have surprising influence on sexual behavior
Researchers have found a surprising new explanation of how young brains are shaped for sexual behavior later in life. Immune cells usually ignored by neuroscientists appear to play an important role in determining whether an animal’s sexual behavior will be more typical of a male or female, according to research led by Kathryn Lenz, an […]
