This school year, many of the nation's adolescents and teens are sitting in class without the device that can sometimes feel like an added appendage: their smartphones. States such as Florida, Indiana ...

Human blood stem cells have been made in a laboratory for the first time, which could significantly improve how we treat certain types of cancer. The lab-grown cells have so far only been tested in ...

Families pay thousands of dollars to store their children’s stem cells with the hope of a healthier future. But the cells are rarely useful, and sometimes contaminated. Anna Lazos with her son and ...

Researchers at UC San Francisco have figured out how to turn ordinary white fat cells, which store calories, into beige fat cells that burn calories to maintain body temperature. The discovery in mice ...

Organelles called mitochondria are transferred to blood-vessel-forming cells by support cells. Unexpectedly, these mitochondria are degraded, kick-starting the production of new ones and boosting ...

Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first ...
