"Most advanced synthetic human embryo models yet spark controversy"

Nature

A pair of studies raises ethical and legal questions about the status of lab-grown human embryo models. Two teams of scientists have announced that they have grown embryo-like structures, made entirely from human stem cells, that are more advanced than any previous efforts. The synthetic embryos developed to a stage equivalent to that of natural embryos about 14 days after fertilization.
