Moderate levels of exercise can modify fat tissue in ways that could improve health, a study on obesity finds.

A hormone secreted by fat cells can restrain the growth of liver cancer in mice, report researchers.

Fat tissue loses function as we age, which can lead to disease. But high levels of lifelong exercise seem to counteract this deterioration, researchers say.

Brown fat may protect against a variety of disease, including type 2 diabetes and coronary artery disease, a new study of 50,000 people shows.

Vitamin D deficiency resulted in stunted growth and additional fat reserves in zebrafish, research shows.

Batteries that can conform to the shape of a robot's body double as protection and far more efficient energy storage could pave the way for new bots.

Evidence that fat-burning neurons can grow in response to leptin suggests a potential way to promote weight loss, say researchers.

Researchers have found signals that start the process of turning fat into heat in mice. It could pave the way for activating the same signals in humans.

"With everything happening right now, this is one thing we can control or manage and it has the potential to help our mental health."

Why do people of different sexes vary in their susceptibility to various diseases? New research points to body fat and the immune system.
