Two new papers describe the generation of so-called blastoids, which could avoid the use of embryonic cells and make studying early human development much more accessible.

Three studies identify unintended consequences of gene editing in human embryos, including large deletions and reshuffling of DNA.

2018 closed with hubbub surrounding the purported birth of babies whose genomes had been edited using CRISPR. What will 2019 hold for CRISPR’s use in humans?

The college has opened an investigation into Michael Deem’s involvement.

New technologies reveal the dynamic changes in mouse and human embryos during the first week after fertilization.

The switch from maternal factors involves dynamic reprogramming of the zygotic genome.

Researchers use base-editing to swap out an erroneous nucleotide responsible for a potentially life-threatening blood disorder.

Six scientists question the authors’ conclusions about the DNA repair process that led to the human embryos’ correction of a defective gene.

Scientists correct a mutation in fertilized eggs that causes a severe cardiac disease.

The embryos, whose genes were altered by CRISPR, were not intended for implantation.
