Common food additives may promote anxiety-related behavior and reduce social behavior in mice, research shows

Food additives known as dietary emulsifiers, commonly found in processed foods to improve texture and extend shelf life, may adversely affect anxiety-related and social behaviors in mice, Georgia State researchers have found. The scientists also observed sex differences in the mice’s behavioral patterns, suggesting that emulsifiers affect the brain via distinct mechanisms in males and […]

Computer model shows how to better control MRSA outbreaks

A research team led by scientists at the Columbia University Mailman School of Public Health report on a new method to help health officials control outbreaks of methicillin-resistant Staphylococcus aureus, or MRSA, a life-threatening antibiotic-resistant infection often seen in hospitals. The researchers are the first to reveal the invisible dynamics governing the spread of these […]

Theranostic complex with two toxic modules shows high toxicity for tumour cells

Emerging cancer nanotechnology enables targeted delivery of drug payloads to cancer sites with concomitant reduction of side effects due to reduced accumulation in critical organs. This prompts research into nanocarriers of therapeutic cargo and contrast agents, allowing combined cancer therapy and tumour visualization, respectively. Researchers from Lobachevsky University of Nizhny Novgorod, Russia, have implemented such […]
