Ethical concerns aside, the genetic ingredients for human traits are so complex that editing a few embryonic genes is unlikely to have much effect — or achieve the fantasy of enhancing humans.

Will AI in health care create a two-tiered system in which poorer people will be seen by a computer instead of a doctor? That's one concern about the burgeoning technology.

The search giant's push into artificial intelligence as a tool for health improvement is a natural evolution for a company that has developed algorithms that reach deep into our lives through the Web.

This could be a crucial year for the powerful gene-editing technique CRISPR as researchers start testing it in patients to treat diseases such as cancer, blindness and sickle cell disease.

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.
