The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Scientists have revealed thepreserved embryos of a 200-million-year-old dinosaur species. Using a state-of-the-art particle ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...
