Think of a small fossil as the equivalent of a homemade video of prehistoric life. Fossils formed when sea organisms began ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is surprisingly conserved across jawed vertebrates. The real differences ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

The international BioRescue consortium has entered new grounds in its mission to save the northern white rhinoceros (NWR, Ceratotherium simum cottoni) from extinction. Since the beginning of the year, ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

Scientists striving to save the northern white rhino have created a new embryo for the subspecies, which has just two living animals left, both of whom are female. At the beginning of 2026, scientists ...

Several animals can pause pregnancy, a strategy called embryonic diapause. This adaptation allows embryos to remain dormant until conditions improve for survival. Kangaroos and bears are among the ...

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 ...
