A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this ...

Researchers created lab-grown models of the human endometrium that allow embryos and blastoids to implant, enabling direct observation of the earliest stages of pregnancy for the first time. The ...

Here’s what a pregnancy looks like inside a microfluidic chip. At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining of the ...

The very beginning of human life, as an embryo inside the womb, has always carried an air of mystery due to technical limitations. For decades, scientists have studied embryos under microscopes and ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as "junk" plays a crucial role in the earliest moments of life. The research, ...
