A UK law allowing gene-edited food has been paused and some British scientists fear being overtaken.

Researchers have developed gene-edited chickens that are partially resistant to bird flu.

The law has changed to allow the commercial development and sale of gene-edited food in England.

Gene-edited food can now be developed and sold in England, but not in the rest of the UK.

Regulations were updated after an outcry over gene-edited babies but a leading expert says they don't go far enough.

Israeli researchers claim to have developed a flock of gene-edited hens that lay eggs from which only female chicks hatch.

Some farmers say they could help tackle looming problems, but the Welsh government remains cautious.

A gene editing technique may prevent the slaughter of animals not needed by the livestock industry.
