A small protein may have a big role in helping you make more bone and less fat, says Dr. Xingming Shi, bone biologist at the Medical College of Georgia Institute of Molecular Medicine and Genetics…

Adult cells of mice created from genetically reprogrammed cells can be triggered via drug to enter an embryonic-stem-cell-like state, without the need for further genetic alteration, a discovery…

When tomatoes ripen in our gardens, we watch them turn gradually from hard, green globules to brightly colored, aromatic, and tasty fruits. This familiar and seemingly commonplace transformation…

Researchers at Children's Hospital Boston say they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes; heart muscle cells. These stem cells, located…
