NIH Mulls Lifting Ethics-Induced Moratorium On Human-Animal Stem Cell Research
Some bioethicists had been concerned about the possibility that animals could start thinking like humans or about what would happen if the chimeras were allowed to breed.

NIH May Restart Funding For Human-Animal Chimera Research
Federal health officials said Thursday they are reconsidering a moratorium on the funding of research in which human tissues are transplanted into early, nonhuman embryos — creating organisms known as chimeras. The proposed rule changes, which the National Institutes of Health announced in a blog post, would allow the agency to pay for experiments that incorporate human tissue into early-stage animal embryos, except for those of primates like monkeys and chimps.

N.I.H. May Fund Human-Animal Stem Cell Research
The National Institutes of Health announced on Thursday that it was planning to lift its ban on funding some research that injects human stem cells into animal embryos. The N.I.H. announced its proposal in a blog post by Carrie Wolinetz, the associate director for science policy, and in the Federal Register. The purpose is to try to grow human tissues or organs in animals to better understand human diseases and develop therapies to treat them. (Kolata, 8/4)

NIH Plans To Lift Ban On Research Funds For Part-Human, Part-Animal Embryos
The National Institutes of Health is proposing a new policy to permit scientists to get federal money to make embryos, known as chimeras, under certain carefully monitored conditions. The NIH imposed a moratorium on funding these experiments in September because they could raise ethical concerns. One issue is that scientists might inadvertently create animals that have partly human brains, endowing them with some semblance of human consciousness or human thinking abilities. Another is that they could develop into animals with human sperm and eggs and breed, producing human embryos or fetuses inside animals or hybrid creatures. (Stein, 8/4)
