A new study reports that the locations where genes begin are particularly prone to mutations, and these genetic changes can ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

In a ground-breaking experiment, researchers have successfully created the first human-monkey chimera. The work, published in the journal Cell, describes the the first embryo containing both human and ...

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 ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

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 ...
