Federal health officials released the latest national measles count Monday. Measles has been reported in 22 states.

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.

The powerful gene-editing technique is moving out of the lab and into the clinic. Trials will use CRISPR to try to treat a variety of diseases, ranging from cancer and blindness to blood disorders.

An international group of 18 prominent scientists and bioethicists is calling for countries around the world to impose a moratorium on the creation of babies whose genes have been altered in the lab.

Researchers think genetically engineered versions of microbes that can live in humans could help treat some rare genetic disorders and perhaps help with Type 1 diabetes, cirrhosis and cancer.

A study of more than 600,000 Danish children finds no evidence of any link between autism and the vaccine that protects against mumps, measles and rubella.

What are some of the leading arguments against this experiment? What happens to other species in the food chain? Isn't developing a vaccine a better way to go?

The insects were created, using CRISPR, to carry a powerful "gene drive." The mosquitoes could provide a potent weapon against malaria, but they raise fears about unpredictable environmental effects.

WHO acted in reaction to a Chinese scientist's announcement in 2018 that he had created the world's first gene-edited babies, a step that highlighted the need for uniform gene-editing guidelines.

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.

A Chinese scientist's claim that he'd created the first gene-edited babies rocked the world this year, raising questions about the ethics of powerful new gene-editing techniques.

U.S. Surgeon General Jerome Adams issued a forceful advisory about vaping by U.S. teenagers, saying electronic cigarette use among young people has reached levels that require urgent action.

A dramatic increase in vaping among high school students is the largest yearly change ever seen in a long-running survey tracking substance use and abuse by teens.

U.S. National Academy of Medicine, U.S. National Academy of Sciences, and Chinese Academy of Sciences call for international gene-editing standards. Critics blast statement as inadequate.

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.

He Jiankui says he undertook the experiment in order to protect the twin baby girls from HIV. The claim is being met with international skepticism and condemnation.

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.
