Animal-human hybrids banned in some states.

From ABC News:

Dren, the half-human, half-animal hybrid set to terrorize Adrien Brody and Sarah Polley in the new movie "Splice," is pure science fiction, but politicians across the country aren't taking any chances.

In the last month Ohio and Arizona have both passed laws forbidding research of animal human hybrids.

Proponents of the laws fear Dren-like creations and object morally to the combining human and animal cells. But scientists say the research could lead to cure for AIDS, immunize people against cancer, or grow replacement organs.

The potential for medical cures or advances is huge, said Esmail Zanjani, a scientist at the University of Nevada Reno who has created sheep that produce livers that are up to 20 percent human.

"But just because we can do something doesn't mean we should," said Zanjani. "We need to have a full discussion with the public," about this kind of research.
