An Australian woman has given birth to identical quadruplet girls after a pregnancy doctors described as incredibly rare.

Adult populations of Aldabra giant tortoises may appear stable, but the number of young tortoises surviving to replace them ...

Animals and their stories of existence have always surprised humans. From the way they are born to their skills of survival, ...

Why humans have a philtrum, the groove above your lip, explained by an evolutionary biologist — from embryonic face-building to vestigial anatomy.

The genes and pathways behind the formation of the first human cell lineages during embryogenesis could have clinical implications for regenerative medicine, pregnancy loss, and infertility. 1. Egg ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

BEIJING -- Chinese researchers have developed a novel technology for semi-cloning in zebrafish, according to a recent research article published in the journal Cell Research. Semi-cloning represents a ...

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 ...

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer See more of our coverage in your ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize themselves following incredibly precise patterns, while remaining flexible ...
