Men with high levels of belly fat are at increased risk of dementia, according to a new study by Monash University researchers of more than 17,000 individuals aged 65 to 98 years in the ASPREE Study.

Even in moderation, consumption of ultra-processed foods is linked with measurable increases in risk for chronic diseases, according to research from the Institute for Health Metrics and Evaluation at the University of Washington. Processed meat, sugar-sweetened beverages (SSBs), and trans fatty acids (TFAs) were associated with an increased disease risk, such as type 2 diabetes, ischemic heart disease (IHD), and colorectal cancer.

Good physical performance is associated with better cognition in people with relapsing-remitting MS, according to a recent study by the University of Eastern Finland. Good functional capacity was also clearly related to cognition and physical performance. The study is published in the Journal of Central Nervous System Disease.

The human brain is comprised of two main types of cells, known as neurons and glia. The first are responsible for transmitting electrical and chemical signals, while the latter support and protect neurons.

Australian scientists have successfully developed a research system that uses 'biological artificial intelligence' to design and evolve molecules with new or improved functions directly in mammal cells. The researchers said this system provides a powerful new tool that will help scientists develop more specific and effective research tools or gene therapies.

Liquid biopsies are tests that detect signs of cancer through a simple blood draw. Unlike traditional biopsies, which require removing a piece of tissue, a liquid biopsy typically looks for mutations or modification changes in fragments of DNA from cancer cells circulating in the blood.

Access to obstetric care is a critical determinant of maternal and infant health. However, a new study led by the University of Minnesota School of Public Health found that hospital-based obstetric care has declined in recent years, with variability across states.
