Ancient DNA is turning human evolution into a crime scene reconstruction, and one of the prime suspects is a herpesvirus that quietly slipped into our chromosomes and never left. By tracing this viral ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

You don't have to be a genius: anemones have been using human genes to form their bodies for 600 million years.

Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Early in pregnancy, something surprising happens. Every human embryo develops a tail. It is not symbolic or imagined. A real ...

Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

A human embryo embeds itself into a fake uterus created by researchers. Screenshot from an Institute for Bioengineering of Catalonia video Sixty percent of miscarriages are caused by the failure of an ...
