Researchers are inching closer to creating human eggs and sperm in the lab that carry a full complement of anyone's DNA. It could revolutionize fertility treatment and raises huge ethical questions.

The experimental technique is an effort to prevent children from inheriting rare genetic diseases. Critics warn that tweaking the genetic code this way could be a slippery slope that leads to designer babies.

An Australian company has lifted the glass cloche on a meatball made of lab-grown cultured meat using the genetic sequence from the long-extinct mammoth. The high-tech treat isn't available to eat yet.

A Mississippi woman's life has been transformed by a treatment for sickle cell disease with the gene-editing technique CRISPR. All her symptoms from a disease once thought incurable have disappeared.

The first brain-delivered gene therapy on the market was recently approved in Europe and the U.K. for a rare genetic disorder called AADC deficiency. It causes developmental delays and movement disorders in kids.

Doctors are divided on whether blanket testing of breast cancer patients is warranted, since scientists and physicians are sometimes unsure about how to interpret the results.

Black and Hispanic people often don't volunteer for studies of Alzheimer's disease, despite their risks for developing it. Researchers are working to make studies more inclusive, but it's not easy.

Medical and genetic data from more than a million Americans are now in scientific databases. Some programs hoard the data, while others share widely with scientists, hoping to speed medical discovery.

Scientists around the world are working to correct a problem with genetic health information — too much of it is currently based on samples of Europeans.

Wanted: A million people willing to share their DNA and 10 years of health habits, big and small, for science.On Sunday, the U.S. government will open…
