A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

Congenital heart defects are the most common form of human birth defect, but we still don’t fully understand what causes them. Previous research had suggested that some heart defects could be ...
