A lot of chatter goes on inside each one of us and not all of it happens between our ears. Researchers at McMaster University discovered that the “cross-talk” between bacteria in our gut and our brain plays an important role in the development of psychiatric illness, intestinal diseases, and probably other health problems, such as […]
Stress can change the balance of bacteria that naturally live in the gut, according to research published this month in the journal Brain, Behavior, and Immunity. Exposure to stress led to changes in composition, diversity and number of gut microorganisms, according to scientists from The Ohio State University. The bacterial communities in the intestine became […]
Researchers have for decades hypothesized that negative emotions lead to inflated reports of common physical symptoms like headaches or an upset stomach. But a new University of Iowa study suggests that two negative emotions – depression and anxiety – influence symptom reporting in different ways. The results were published in the latest issue of the Journal […]
Concerns over vaccination seems to have permeated society, and parents have many questions about the safety of vaccines. One important question is whether vaccinations strain or weaken children’s immune systems and are therefore harmful to them. Roma Schmitz and her colleagues from the Robert Koch Institute investigated this research question in the current issue of […]
A team of scientists from across the globe have found that gut bacteria may influence mammalian brain development and adult behavior. The study is published in the scientific journal PNAS, and is the result of an ongoing collaboration between scientists at Karolinska Institutet in Sweden and the Genome Institute of Singapore. Check the end of […]
Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why. The investigators show that “good” bacteria in the gut keep the immune system primed to more […]
