New examinations of skeletons and animal embryos have allowed researchers to discover how mammals developed protruding, flexible noses. This study contributes to uncovering the origin of mammals' ...

In a bid to improve organ transplant options in the future, a team led by researchers at the Chinese Academy of Sciences has shown that it's possible to produce pig embryos containing "humanized" ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post ...

The embryos of many species can stop developing when starved of nutrients, only to restart the process once these are restored – and scientists may have figured out how they do it. In the early stages ...

A team at the University of Cambridge has announced making the first human “synthetic embryos” – embryo-like structures made from stem cells – that have been grown to a stage equivalent to just past ...
