Fat location, not BMI, drives heart ageing risk in men and women

Researchers using UK Biobank imaging data found that where fat is stored in the body, not just how much, determines cardiovascular ageing. Visceral, liver, and muscle fat accelerate ageing, while gynoid fat protects women before menopause.

Small peptide produced by gut bacteria identified as key factor in kidney fibrosis

A molecule made by bacteria in the gut can hitch a ride to the kidneys, where it sets off a chain reaction of inflammation, scarring and fibrosis - a serious complication of diabetes and a leading cause of kidney failure - according to a new study from researchers at the University of Illinois Urbana-Champaign and Mie University in Japan.

African swine fever vaccine shows variable protection across virus strains

An international team of scientists has found that a promising African swine fever (ASF) vaccine can protect pigs against some strains of the virus but offers little or no protection against others. The findings point to the need for region-specific vaccines to tackle one of the world's most devastating animal diseases.

Neural signature reveals how self-preoccupation manifests in the brain

People tend to be self-preoccupied. Self-interest is good when it ensures that one's needs are met, but it can also be maladaptive; research shows that the tendency to self-focus promotes the occurrence of depression and anxiety and can even prolong these conditions.
