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 ...

Like schools of fish and flocks of birds, our cells can also migrate collectively in coordination with their neighbors. This ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Caltech researchers have now developed a bioengineered coordinate system to observe the movement of cellular machinery. The research enables a better understanding of how cells create order out of ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...
