BIRMINGHAM, Ala., Dec. 7 (UPI) -- U.S. researchers say they have developed a new stem cell technique that successfully treats sickle cell anemia in mice.

CAMBRIDGE, Mass., June 11 (UPI) -- U.S. scientists reportedly have created embryonic stem cells without eggs by genetically manipulating mature skin cells taken from mice. Embryonic stem cells are unique because they can develop into virtually any kind of tissue type -- an attribute called

CAMBRIDGE, Mass., Feb. 1 (UPI) -- Scientists at Whitehead Institute for Biomedical Research in Cambridge, Mass., report reducing some symptoms of Rett Syndrome in mice.

WASHINGTON, Oct. 25 (UPI) -- A United Nations proposal to ban all cloning of human embryos -- including that done for research or therapeutic purposes -- will shift but not stop the research, experts agreed.

CAMBRIDGE, Mass., Feb. 16 (UPI) -- U.S. cloning researchers used a gag from a Woody Allen movie to successfully clone mice from cells in their noses.

BOSTON, Sept. 10 (UPI) -- Scientists have found further evidence that cloned animals tend to harbor genetic defects that will disrupt their development and lead to abnormalities, strengthening the rational that reproductive cloning of humans should be banned.
