Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

A study reveals that consuming ultra-processed foods may affect men's fertility and early embryo development. While men risk ...

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 — ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Eggs take exactly 21 days to hatch, and the process of chick development is an exciting opportunity for your students! We are working to create lessons, videos and resources for you to use in your ...

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made ...
