Soon, protection from HIV infection could be as simple as inserting a medicated, disappearing fabric minutes before having sex. Bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV.

Researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person's risk of attempting suicide.
Researchers have established a new strategy to help surgeons see the entire tumor in a patient. This approach relies on an injectable dye that accumulates in cancerous tissues much more so than normal tissues. When the surgeon shines an infrared light on the cancer, it glows, allowing the surgeon to remove the entire malignancy.
The microbes living in the guts of males and females react differently to diet, even when the diets are identical, according to a new study. These results suggest that any therapies designed to improve human health through diet should take into account whether the patient is male or female.
By studying the injuries and aptitudes of Vietnam War veterans who suffered penetrating head wounds during the war, scientists are tackling - and beginning to answer - longstanding questions about how the brain works. The researchers found that brain regions that contribute to optimal social functioning are also vital to general and emotional intelligence.
Researchers have discovered how the protein p53-psi, a variant of the well-known anti-cancer guardian protein p53, can reprogram cells to "switch sides" and acquire pro-metastatic features.
Some people can handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond. Researchers have identified a specific electrical pattern in the brains of genetically identical mice that predicts how well individual animals will fare in stressful situations.
The U.S. should significantly reform the federal system for financing physician training and residency programs to ensure that the public’s $15 billion annual investment is producing the doctors that the nation needs, says a new report by the Institute of Medicine.
Police officers were deployed to Liberia's international airport to ensure passengers are screened for Ebola symptoms as a major regional airline announced Tuesday it was suspending flights to the cities hardest hit by an outbreak that has killed more than 670 people.
A costly drug given mostly to premature babies is at the center of a clash between the manufacturer and the nation's leading pediatrician's group, which recommends scaling back use of the medicine. The dispute involves new guidelines from the American Academy of Pediatrics, which say medical evidence shows the drug benefits few children other than very young preemies.
A new study from UC San Francisco is the first to show that while the impact of life's stressors accumulate overtime and accelerate cellular aging, these negative effects may be reduced by maintaining a healthy diet, exercising and sleeping well.
Smartphones and mobile devices are on the cusp of revolutionizing health care, armed with mobile health (“mHealth”) apps capable of providing everything from cardiac measurements to sonograms. While tremendous potential exists to broaden access to medical treatment and control costs, several health law experts say more oversight is needed by the FDA to ensure consumer confidence and safety.
Researchers have identified a combination of pills that cures 9 of 10 hepatitis C patients. The combination of the drugs sofosbuvir and simeprevir, with or without ribavirin, cured 93 percent of patients in 12 weeks, and was well tolerated by all.
Researchers have devised a simple blood test that can be used to diagnose whether people have cancer or not. The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures, such as colonoscopies and biopsies.
Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson's disease, including six that had not been previously reported.
In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidences of acute respiratory symptoms.
A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years.
Prosecutors in Northern California say they have obtained an arrest warrant for a tuberculosis patient who has refused treatment and may be contagious, putting those around him at risk. By law, health officials can't force a patient to be treated for tuberculosis, but officials can use the courts to isolate him from the public.
Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. Tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading. One pioneering approach uses nanoparticles to jumpstart the body's ability to fight tumors.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug. The study is the first to show that melatonin is vital to the success of tamoxifen in treating breast cancer.
The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.
For the first time ever, researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery is also relevant for other infectious diseases including bacterial infections and tuberculosis.
Only 8.2 percent of human DNA is likely to be doing something important, or is “functional.” This figure is very different from one given in 2012, when some scientists involved in the ENCODE project stated that 80 percent of our genome has some biochemical function.
Parts of the primordial soup in which life arose have been maintained in our cells today. Research reveals how cells in plants, yeast and very likely also in animals still perform ancient reactions thought to have been responsible for the origin of life- some four billion years ago.
Could the body's own immune system play a role in memory impairment and cognitive dysfunction associated with conditions like chronic epilepsy, Alzheimer's, dementia and concussions? According to a new study, yes.
