The agency raided one that was using a stem cell-smallpox vaccine combo, and sent a warning to another to obey best practices.

In mice lacking intestinal microbiota, white fat turns brown and obesity is prevented.

Adipogenesis in mice has alternating genetic requirements throughout the animals’ lives.

Obese people are at higher risk for developing cancer, have worse prognoses once diagnosed, and are often resistant to chemotherapy regimens. The question is, Why?

Factors that likely contribute to obesity include disruptions to intercellular signaling, increased inflammation, and changes to the gut microbiome.
 

Scientists know how to turn on these fat-combusting cells. Can these energy burners be used to combat obesity?

Following extreme trauma, patients’ adipose samples have revealed—for the first time in humans—that white fat can be converted into energy-burning brown fat.

The origins of adipocytes have been hotly debated, but a human study supports the idea that the bone marrow takes part. 

Artificially extended days cause mice to gain fat and alter the function of their brown fat, a study shows.

Transplanting energy-burning brown fat can prevent excess weight gain in a mouse model of obesity.
