A new study found that children on the threshold of obesity or overweight in the first two years of life had lower perceptual reasoning and working memory scores than lean children when tested at ages five and eight. The study also indicated that IQ scores may be lower for higher-weight children.

Previous studies have found an association between two commonly used agrochemicals (paraquat and maneb) and Parkinson’s disease. Now a professor has determined that low-level exposure to the pesticides disrupts cells in a way that mimics the effects of mutations known to cause Parkinson’s disease. Adding the effects of the chemicals to a predisposition for Parkinson’s disease drastically increases the risk of disease onset.

Scientists have found a connection between bacteria in the gut and antitumor immune responses in the liver. Bacteria found in the gut of mice affect the liver’s antitumor immune function. The findings have implications for understanding the mechanisms that lead to liver cancer and for therapeutic approaches to treat them.

A new technique to study fat stores in the body could aid efforts to find treatments to tackle obesity, research suggests. The approach focuses on energy-burning tissues found deep inside the body — called brown fat — that help to keep us warm when temperatures drop.

The volume of carbohydrates, proteins, lipids and calories consumed by very vulnerable preemies significantly contributes to increased brain volume and white matter development, however additional research is needed to determine specific nutritional approaches that best support these infants’ developing brains.

Researchers have elucidated a mechanism by which ‘good’ bacteria that reside in our gastrointestinal tract can help protect us from inflammation, and how their disruption (dysbiosis) can increase the susceptibility of the liver to more harmful forms of disease. Their study identified two key metabolites produced by the bacteria in mice that modulate inflammation in the host and could ultimately reduce the severity of non-alcoholic fatty liver disease.

New research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The groundbreaking study fundamentally alters brain and nervous system medicine — giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.
