6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos heats up.

Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after ...
