Same-Sex Mice parents give birth to healthy bread

Baby-making science has exceeded a new threshold, at least in rodents. A team of scientists in China has succeeded in creating a small number of apparently healthy mouse pups of female parents of the same sex. The researchers also produced offspring from two mouse fathers, but these puppies all died shortly after birth, underlining the fact that the new technique is still faced with serious obstacles.

The team's approach, based on stem cell science and CRISPR-Cas9 gene processing, is a "new way to produce offspring from same-sex mammals," says senior author Qi Zhou, who works on stem cells and reproductive biology at the Chinese Academy of Sciences.
