Certain viruses attack bacteria and can sometimes clear antibiotic-resistant infections. Researchers said they had tailored a virus to attack one patient’s illness.

Our genes evolved to fight ancient threats, but in the modern world, some of those changes may be turning against us.

Traditional gene editing rewrites DNA. But a new approach, called epigenome editing, aims to treat the molecular scars we collect throughout our lives.

Scientists trained artificial intelligence on libraries of DNA and then asked the model to create recipes for viral genomes. Sixteen of them were viable, yielding new viruses.

Genetic prediction models are poised to revolutionize medicine. But because they have been trained on European DNA, they threaten to widen health care disparities.

Remains of the man, Joseph Louis Serrao Jr., discovered in a remote area in Olympic National Park in 2000, were identified using forensic genealogy.

Her decades of work on Huntington’s disease helped lead to the creation of a genetic test for the devastating condition. Why didn’t she take it herself?

Fertility specialists, biotech companies and ethicists are divided over whether progress in early gene editing would wipe out diseases or trigger a rush toward enhancement.

He mapped the herpes simplex virus genome, revealing how it invades cells. His work also helped lay the groundwork for potential vaccines and gene therapies.

As predictive medicine advances, legal scholars warn that decades-old federal guidelines could set up a potential clash between your genes and your job.

The types of Ebola and hantavirus worrying officials are very different from the species identified decades ago, raising new questions about how to respond.
