An embryo is formed as a result of the fertilisation of an egg by a sperm, and that's what goes on to develop into a foetus. But what if an embryo could be created using only stem cells instead, sidestepping the need for eggs or sperm? That's what a team from the University of Cambridge and the California Institute of Technology said they've successfully done. Here to help us understand what exactly these scientists have created and the ethical issues with these kinds of research, is neurogeneticist Dr Azlina Ahmad Annuar, joining us as always for her Brain Waves series.
