In this story from January 2006, NOVA scienceNOW reports on stunning developments in the field of stem cell research. The South Korean scientist heralded a year earlier for his innovative research is found guilty of fabricating his results, including reportedly groundbreaking work cloning human embryonic stem cells. The Korean fiasco casts a cloud over the field, but U.S. researchers still move forward, believing that embryonic stem cells hold great potential for medicine. As part of this advancement, a team led by Rudolf Jaenisch at MIT explores a way to produce embryonic stem cells without using an embryo that can develop into a fetus.
