The overuse of antibiotics has created strains of bacteria resistant to medication, making the diseases they cause difficult to treat, or even deadly. Now, a research team has identified a weakness in at least one superbug that scientists may be able to medically exploit.
While studying a mutant strain of yeast, researchers may have found a new target for drugs to combat cholesterol and fungal diseases.
Previous studies found that smokers with COPD had the most significant decrease in one of the enzymes controlling chemical modifications to DNA, called HDAC2. Now, researchers showed that development of progenitor cells in the lung is specifically regulated by the combined function of two highly related HDACs, HDAC/1 and /2.
Popping calcium and vitamin D pills in hopes of strong bones? Healthy older women shouldn’t bother with relatively low-dose dietary supplements, say new recommendations from a government advisory group. Both nutrients are crucial for healthy bones.
A New Jersey jury has awarded $3.35 million to a former nurse who says Johnson & Johnson's vaginal mesh implant caused severe chronic pain despite 18 unsuccessful repair surgeries. It's the first verdict in about 4,000 lawsuits filed against the health products maker.
In research that could one day improve the success of stem cell transplants and chemotherapy, scientists have found that distinct niches exist in bone marrow to nurture different types of blood stem cells.
The U.S. Food and Drug Administration on Monday expanded approval of a Bayer cancer pill to treat tumors of the intestinal tract that do not respond to other treatments. The drug is called Stivarga and regulators approved it to treat gastrointestinal stromal tumors.
A new study provides clinical evidence of the safety and effectiveness of a new magnetic medical device to treat gastroesophageal reflux disease (GERD).
Drug companies Affymax Inc. and Takeda Pharmaceutical Co. have issued a recall of their anemia drug Omontys after reports of severe allergic reactions in some kidney dialysis patients, including some deaths. The companies said that more than 25,000 patients have received Omontys, which is used...
The U.S. Food and Drug Administration has approved a first-of-a-kind breast cancer medication that targets tumor cells while sparing healthy ones. The drug Kadcyla from Roche combines the established drug Herceptin with a powerful chemotherapy drug and a third chemical linking the medicines...
A drug that is currently used for cancer can relieve and slow down the progression of the autoimmune disease multiple sclerosis (MS) in rats, according to a new study. The discovery might one day lead to better forms of treatment for patients with MS.
A new class of influenza drug has been shown effective against drug-resistant strains of the flu virus, according to a study.
A panel of advisers to the European Union's health agency has again rejected Vivus Inc.'s weight-loss drug for sale in Europe. Vivus, based in Mountain View, Calif., said that the Committee for Medicinal Products for Human Use confirmed its October decision to decline an application to sell the drug under the name Qsiva.
For those 65 and older, this season's flu shot is only 9 percent effective against the most common and dangerous flu bug, according to a startling new government report. Flu vaccine tends to protect younger people better than older ones and never works as well as other kinds of vaccines.
Scientists have made important advances in understanding why our immune system can attack our own tissues resulting in eye and kidney diseases.
Cornell University researchers showed it is possible to create a replacement ear using a 3-D printer and injections of living cells. The work is a first step toward one day growing customized new ears for children born with malformed ones or people who lose one to accident or disease.
An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team of researchers.

A team of scientists and surgeons are developing a new nasal spray from a marine microbe to help clear chronic sinusitis.
Researchers exploring the complex stream of cellular signals produced by the body in response to a traumatic injury believe the initial response– formation of a blood clot– may control subsequent healing. Using that information, they’re developing new biomaterials, including artificial blood platelets laced with regulatory chemicals, that could be included in an injector device the size of an iPhone.
