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

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

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 - ...

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 ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...
