Getting a grip on the yuck factor
For the millions of diminutive fans of Peppa Pig there is almost nothing cuter than a talking piglet. Outside cartoon land the boundary between pig and human is also blurring; and the response, in some quarters, is less enthusiastic.
In January 2017 a team led by Juan Carlos Izpisua Belmonte, at the Salk Institute in California, announced it had introduced human stem cells into pig embryos. The result was a hybrid embryo, part pig, part human. Such creations are called chimeras, after the mythological creature that blended lion, goat and snake.
