In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
Marijuana is legal to use for medical purposes in 28 states and the District of Columbia, but the quick development of this new industry could have left some regulation issues in the lurch.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.

Using a technology we like to call "Hive Computing," several Android apps allow you to contribute idle processing power to help further scientific research. This basically means that when you're not using your phone or tablet, it can join forces with other idle devices to form a supercomputer that scientists can use to potentially make a world-changing breakthrough.

Whites are the hardest color to keep looking bright and new after just a few months' time. Your sweat and oils quickly become stains, and colors from other clothes will eventually bleed into the fabric, discoloring your bright whites into something merely whitish. But before you reach for the bleach, the ultimate chemical cleaner, try some a few of these safer, less-toxic DIY solutions out instead.
Modern medicine utilizes cutting-edge technology more than ever, so it would only make sense that the powerful handheld computers we all carry around these days could play a big role in wellness.
No one ever wants to experience pain, whether it's as small as a stubbed toe or as great as recovering from surgery. Yet so much of our lives causes pain, lasting or brief in its form.

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

We won't cover it here, but so that you know, covering the wound with a sterile dressing or band-aid is a good idea.
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.

Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers.
