'Human' cells mixed with chicken embryos; experiment slammed
In a first, US-based scientists mixed lab-grown human cells with chicken embryos, where human cells directed them to grow into nervous tissue. Scientists said the research could lead to new ways of preventing miscarriages and birth defects. Although the hybrids didn't last long, Twitter users slammed the experiment saying, "I don't care if you're trying to cure diseases, it's inappropriate."
