Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining ...

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...
