May 23, 2013 Biologists said last week that they had overcome a major obstacle in stem-cell research by cloning human embryos. But several images in the published study were duplicated and labeled incorrectly, prompting questions about the authenticity of the results.
May 16, 2013 The news that scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the creation of Dolly the sheep. It's a fight that has, over the past decade and a half, produced a lot of heat and light and not a lot of policy.
May 15, 2013 After decades of trying, scientists say they've finally figured out how to make personalized embryonic stem cells. One day, these designer cells may help treat an array of diseases. A jolt of caffeine and and a little electric shock helped to do the trick.
October 8, 2012 John Gurdon and Shinya Yamanaka discovered that every cell in our body — from skin and heart to brain and lung — can reinvent itself and become any other cell type. These stem cells have vast potential for drug development, for many diseases, like Alzheimer's, muscular dystrophy and diabetes.
October 8, 2012 John B. Gurdon and Shinya Yamanaka discovered that mature and specialized cells "can be reprogrammed to become immature cells capable of developing into all tissues of the body," according to the Nobel committee.
September 3, 2012 The path to better medical treatments may require us to rethink how we carry out the testing of new therapies, argues commentator Stuart Kauffman.
August 1, 2012 Three separate teams of scientists have shown that so-called cancer stem cells can be found in brain tumors and early forms of skin and colon cancer. Evidence has been mounting in recent years for the existence of these cells, which are believed to resist standard chemotherapy and fuel the growth of tumors and relapses.
February 7, 2012 Despite raising millions of dollars for breast cancer research, the Susan G. Komen for the Cure foundation hasn't funded any work involving human embryonic stem cells. Other big disease charities have also shied away from funding such science.
January 30, 2012 Gingrich has long been a strong backer of federal funding for scientific research. In 2001 his support extended to research on stem cells derived from human embryos left over from in vitro fertilization efforts.
