In his dogged determination to continue cloning, Woo-Suk Hwang had requested that he be allowed to resume human cloning work. But now South Korea's National Committee on Bioethics has denied Hwang's request to work with human eggs and embryos. Hwang is still on trial for fraud, embezzlement, ethical breaches and other charges stemming from his human cloning fraud. As part of the fallout, South Korea's parliament recently tightened its bioethics laws somewhat, prohibiting cross-species cloning to form animal-human hybrid embryos (using animal eggs and human nuclei.) While Hwang awaits the verdict on his charges, he has occupied himself with animal cloning, such as cloning dogs, including Booger. No word yet on when the cloned mammoth will be ready.
