A New Form of Stem-Cell Engineering Raises Ethical Questions

As biological research races forward, ethical quandaries are piling up...In the journal eLife, researchers at Harvard Medical School said it was time to ponder a startling new prospect: synthetic embryos.

In recent years, scientists have moved beyond in vitro fertilization. They are starting to assemble stem cells that can organize themselves into embryolike structures.
