Earlier efforts to use gene therapy to treat a rare immune disorder in young children failed when some of the children got leukemia. Scientists say they think they may have figured it out, with eight children now living normal toddler lives.
Here you can find out how the practice of medicine is changing. We pull together the latest research on medical tests, drugs and other therapies.
While the company tries to work things out with regulators, it won't be telling people who buy its test if their genetic profiles predispose them to particular illnesses or predict their responses to prescription drugs.
The only person known to have been cured of AIDS got a bone marrow transplant, so when two AIDS patients in Boston appeared to be free of the virus after transplants, scientists hoped they were cured, too. But the HIV virus has returned in both.
The august medical journal JAMA created a kitsch masterpiece for the cover of its annual issue dedicated to medical education. A group of seven canine healers, some apparently in training, hover around a sick mutt sucking on a thermometer in a hospital bed. They look an awful lot like some poker-playing dogs from yesteryear.
The first in a new class of drugs that can cure the viral infection that is the leading cause of liver failure and liver cancer is poised for a marketing green light from the Food and Drug Administration. More than 3 million Americans have hepatitis C, but most don't know it.
For years doctors have been telling women that it's risky to implant multiple embryos when they do in vitro fertilization. They've listened, and the number of multiples from IVF has dropped. But the number of births of triplets or more has barely budged because of women's use of fertility drugs.
For a class project, three engineering students at Rice University devised an inexpensive robotic arm to help a teenager with an uncommon bone disease. The work took two years to complete, far longer than the class that was its starting point.
People's genes can affect how they'll respond to blood thinners and cancer drugs. But inaccurate results can lead to bad medical decisions. Regulators are pushing back against a company that has been among the most aggressive in marketing personal genetic testing directly to consumers.
Updated just last week by the American Heart Association and the American College of Cardiology, the new guidelines are based on old data, some heart doctors say, and may overestimate the real risk of heart attack and stroke. That could result in overtreatment with cholesterol-lowering drugs.
The Food and Drug Administration approved a pacemaker-like device for patients whose epilepsy can't be controlled with drugs. The device senses when seizures are coming and stops them by sending electronic signals through wires inserted deep in the brain.
