Getting DNA into plant cells is tricky. Researchers have tried using infectious bacteria, as well as gene guns that shoot gold bullets. Then a physicist came up with a new approach almost by accident.

Despite outrage over gene editing in China that affected the birth of twins, research is underway in the U.S. to assess the safety and effectiveness of CRISPR tools to edit genes in human embryos.

Concerns over a Chinese scientist's claim that he created the first gene-edited babies grow with more questions about whether it worked and the possible harm he may have inflicted on the twin girls.

The Second International Summit on Human Genome Editing issues a consensus on how scientists might responsibly move forward to create gene-edited babies in the wake of a rogue scientist's claims.

He Jiankui, who shocked the world by asserting he had genetically edited twin girls, faced growing criticism from other researchers as he spoke at a scientific conference in Hong Kong.

A scientist says he created the first genetically edited babies using CRISPR to protect them from HIV infection. The move has prompted immediate criticism as premature and reckless.

A committee of experts examined about a dozen different synthetic biology technologies that could be potentially misused. For each, they considered how likely it was to be usable as a weapon.
