Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

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 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.

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 ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.

Our lofty friends, the giraffes, are slowly and quietly disappearing from the wild. Some organizations are trying to help ...
