Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

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

In the earliest stages of life, mammalian embryos start as a disorganized cluster of cells. As development progresses, these cells become organized into well-defined shapes and structures. This ...

The giant Australian cuttlefish annually return to the waters of the Upper Spencer Gulf, near Whyalla, in their tens of thousands for its breeding season. But this year, barely any have arrived.

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

A DNA-editing feat involving editing the genes of early stage embryos—a far cry from designer babies, but nevertheless a step in that direction—was announced this week. Dieter Egli, an associate ...

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

Fertility specialists, biotech companies and ethicists are divided over whether progress in early gene editing would wipe out diseases or trigger a rush toward enhancement. By Emily Baumgaertner Nunn ...

A preprint describing genetically edited human embryos is raising concerns among scientists that the U.S. is becoming more accepting of using gene editing to enhance embryos. “The cat’s out of the bag ...
