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

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 ...

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 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 ...

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 ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

Analyzing genetic data from nearly 140,000 IVF embryos, researchers linked maternal DNA variants to increased risk of ...

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the ...
