December 6, 2013 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.
November 4, 2013 Scientists are asking people to contribute samples of their gut microbes to help figure out how those microbes affect human health. But ethicists say sharing that information, as well as the personal health data that make it useful to researchers, poses risks. That's especially true for children.
October 18, 2013 Researchers say naturally occurring viruses that target bacteria might one day help help treat human infections with germs that are resistant to antibiotics. The research is still in the early stages, and there are quite a few challenges to overcome before a treatment can even be tested in humans.
October 11, 2013 Researchers at the University of Florida are suggesting that the smell test could determine whether someone is in the early stages of Alzheimer's. But the discovery comes with caveats and lots of skepticism about how useful a test it would really be.
October 9, 2013 The three scientists sharing the 2013 Nobel Prize for chemistry developed computerized tools for studying complex molecules, such as enzymes and the photosynthesis machinery. These techniques allow engineers to design drugs and new chemical reactions more quickly and cheaply.
August 14, 2013 An analysis of 16 recent medical guidelines found evidence of financial ties between key experts and industry. Most of the recommendations expanded the definitions of common illnesses, lowering the threshold for treatment.
July 30, 2013 Some ibuprofen and maybe some physical therapy are all it takes to make most back pain go away. But a study finds that doctors and patients are increasingly turning to fancy scans and opioid painkillers. They typically don't help, and increase the risk of addiction and overdose.
March 27, 2013 Doctors are desperate for better treatments for hepatitis C, which now affects about 4 million Americans. A new kind of drug that "mops up" molecules in the cells stopped the virus in a small clinical study, offering hope for a quicker cure with few side effects.
September 6, 2012 Testing everyone for HIV and then giving them early treatment could theoretically eliminate the epidemic in South Africa. A mathematical model of this "test and treat" strategy suggest that it might be more expensive and take significantly longer than previously predicted.
June 22, 2012 Fibromyalgia patients have limited treatment options, but a Canadian study finds that those who self-medicate with marijuana were more likely to have poor mental health and to seek other drugs.
April 19, 2012 Patients can often skip expensive treatments for simpler, cheaper alternatives. That's the gist of a new campaign from the American College of Physicians. But they've got to convince not just patients, but doctors, too.
