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 ...

Metabolism does more than fuel embryos—it sets their developmental rhythm. EMBL researchers found that a sugar molecule, FBP, ...

Scientists have sought to capture the first days of how a person comes to be, by recreating those early moments in a lab via models made up of induced pluripotent stem cells, or IPSCs.

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow ...

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 ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow ...

Scientists have for the first time ever filmed a crucial step that leads to new human life – cracking open a 'black box' of early development, and potentially helping with fertility treatments. Every ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. In ...
