New research shows it’s possible to edit the DNA of human embryos with more precision. But scientists warn it’s still not ...

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 ...

Base editing in human embryos reveals that NANOG is the one gene required to form every body tissue. Cambridge’s landmark ...

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 ...

Base editing, the process used to make the changes, only nicks one strand of DNA, avoiding the major DNA errors that made ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique ...

Companies aim to edit germlines, which they say could prevent a range of diseases. But do people want the tech?

Chinese researchers have mapped the world's first complete spatiotemporal gene expression atlas of human embryos during the critical organ-forming period from four to eight weeks post-fertilization.

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

An Adelaide University study has revealed that per- and polyfluoroalkyl substances (PFAS) found in tap water, at levels currently considered safe, affected the development of embryos, causing ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...
