By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells ...

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while ...

A study in newborn chicks shows that brain lateralisation is essential for the development of a left-to-right mental number line.

Lateralization of the brain – the tendency for the left and right hemispheres to specialize in different functions – underlies the development of a left-to-right mental number line, according to a ...

In a quiet lab at Cornell University, scientists have made a discovery that could reshape how we think about life’s earliest ...

Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...
