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 ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

The viral transposable element, MERVL, acts as a central switch during early embryonic development, driving totipotent gene ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

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 ...
