Those South Korean Clones: When South Korean scientists claimed to have successfully cloned a human embryo, it raised a lot of eyebrows because of the unusually large number of donor eggs they were able to obtain for their research. The journal Nature reported recently that they came from graduate students:

After interviewing one of Hwang's Ph.D. female students, Nature reported the student initially told the journal the egg donors included herself and another woman in the lab.

According to Nature, the student called back later and said that she had not donated eggs, blaming her poor English for a misunderstanding.

The journal reported that during the first interview she named the hospital where her donation was carried out and explained that she had been happy to donate eggs because she already has two children.

The graduate student, and her boss, now deny everything.
