People with pockets of fat hidden inside their muscles are at a higher risk of dying or being hospitalized from a heart attack or heart failure, regardless of their body mass index, according to new research. This 'intermuscular' fat is highly prized in beef steaks for cooking. However, little is known about this type of body fat in humans, and its impact on health. This is the first study to comprehensively investigate the effects of fatty muscles on heart disease. The new finding adds evidence that existing measures, such as body mass index or waist circumference, are not adequate to evaluate the risk of heart disease accurately for all people.

Cutting-edge fluorescent cholesterol probes now enable scientists to visualize cholesterol movement and distribution in live cells with unprecedented detail. By combining computer simulations with live-cell imaging, researchers have uncovered how different probe designs influence cholesterol probe behavior. These probes could reveal how cholesterol imbalances drive Alzheimer's and other neurodegenerative disorders, aiding drug development to modulate lipid activity and potentially offering new treatments or prevention strategies.

Fetuses of pregnant people who gained excess weight in the first trimester of pregnancy show signs of excess fat distribution in the upper arm and in the abdomen, according to a new study. These findings may inform efforts to prevent excessive weight gain early in life, a risk factor for adult obesity and related conditions, such as heart disease, high blood pressure and diabetes.
