Artificial embryos built from scratch using stem cells have been created by scientists.
Researchers bypassed the act of fertilisation by growing the self-assembling structures in the laboratory.
Although the cells used came from mice, the experiment has opened up a new frontier in embryo research with major ethical implications.

Creating embryos in the lab is expected to help scientists unlock the mysteries of early human development.
