Most gene-editing tools cut DNA wherever they’re pointed, with no way to tell a tumor cell from a healthy one. A study ...

Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

A major medical milestone took place in May 2025, when doctors at the Children’s Hospital of Philadelphia used CRISPR-based gene editing to treat a child with a rare genetic disorder. Unlike earlier ...

The CRISPR gene editing technique has had a dramatic influence on biomedical research, and has even been applied to a few humans to treat disease. Since its invention, scientists have improved, ...

First it was human embryos. Now scientists are trying to develop another way to modify human DNA that can be passed on to future generations, NPR has learned. Reproductive biologists at Weill Cornell ...
