The downside of the genetic testing boom

Genetic testing is advancing and evolving so quickly that it's causing chaos for some patients, the Wall Street Journal reports.

Driving the news: Patients may receive one diagnosis and begin treatment, only to receive a different diagnosis a few years later through more advanced testing.

A new hope for fighting drug-resistant infections

Researchers said they successfully treated a patient's drug-resistant infection using genetically engineered viruses, the Wall Street Journal reports.

Why it matters: This is the first reported use of genetically engineered bacteriophages to treat a patient, according to the researchers. If its success can be replicated, that could be a big deal for the effort to tackle drug-resistant infections.
