> A normal version of the tumor suppressor gene p53, rather than a mutated version, appears to make breast cancer chemotherapy with doxorubicin less effective, researchers have concluded at The University of Texas MD Anderson Cancer Center in Houston. Release

Stem Cells

> It is now possible to grow human bone from stem cells in a laboratory, scientists from the Bonus Bio-Group and Tech-nion Institute of Research have determined. Story

> Scientists are in urgent need of standardized research guidelines to help control and encourage development of new stem cell treatments and gene therapies, a new report from GBI Research concludes. Story

Genetics

> Researchers have discovered two more genetic variants that link to migraines without aura, the most common type of the condition. Story

> At McLean Hospital, one-third of the world's largest collection of autism brain samples has been severely damaged, thanks to a freezer malfunction. Some fear that genetic research could face major delays as a result. Story
