Published since 2005. San Francisco is a city that belongs to the people of the world. Hence this blog has a global focus.

In today's online edition ofScience, researchers describe using induced pluripotent stem (iPS) cells to alleviate symptoms of sickle cell anemia in mice. The technique is not yet safe to try in people, but scientists say it is proof of principle that iPS cells could someday treat human disease.
