Scientists have discovered that both brown and white fat is filled with thousands of previously unknown microproteins, and show that one of these microproteins, called Gm8773, can increase appetite in mice. These findings could lead to the development of a therapeutic to help people gain weight in certain disease situations, such as during chemotherapy for cancer.

Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging. By capturing and amplifying tiny sound waves created when X-rays heat tissues in the body, medical professionals can map the radiation dose within the body, giving them new data to guide treatments in real time. It's a first-of-its-kind view of an interaction doctors have previously been unable to 'see.'
