What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

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 ...

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 production ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

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.

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 ...

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 team of researchers at the Institute for Bioengineering of Catalonia (IBEC) in Spain has succeeded, for the first time, in recording in real time and in 3D the implantation of a human embryo. This ...

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 ...

Collaborating institutions in Taiwan report higher risks of atopic disease among children conceived via assisted reproductive ...

Which genes are required for turning embryonic stem cells into brain cells, and what happens when this process goes wrong? In ...

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 - ...
