Men have nipples because embryos are sexually neutral for their first six weeks. Here's the developmental blueprint behind ...

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

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 ...

When planning a trip, it's rare that you don't have a choice of route. One may be more direct, another more scenic; but regardless of the time or route taken, the destination is the same. This concept ...

Researchers led by developmental biologist Kathy Niakan at the University of Cambridge have used base editing in human embryos to learn more about human embryonic development. By deactivating a gene ...

Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its ...
