How to tell whether you have athlete’s foot or eczema
Eczema and athlete’s foot cause similar symptoms, making them difficult to tell apart. However, eczema typically appears around the elbows and knees, while athlete’s foot typically affects the toes and feet. Despite their similar symptoms, the two conditions are unrelated. Environmental and genetic factors contribute to eczema, while athlete’s foot is the result of a...
Scientists find the brain cells that drive us to eat fat, sugar
Specific neurons in the brain may drive our overeating behavior. mikroman6/Getty Images Researchers investigated the neural activity underlying the consumption of fatty and sugary foods and activity levels. They looked at the effect of a specific cluster of neurons in the brain’s emotional center—the amygdala— on energy consumption and energy expenditure. They tested this by turning...

Family of DNA damage–inducing microbial metabolites found in guts of people with IBS
by Bob Yirka, Medical Xpress Human gut microbes isolated from IBD patients produce small-molecule genotoxins. Diverse gut microbes isolated from patients with IBD exhibit direct genotoxicity. M. morganii produces a family of genotoxic small molecule metabolites, termed the indolimines. Indolimine-producing M. morganii induces DNA damage in intestinal epithelial cells (IECs) and increased colon tumor burdens...
