News: Scientists Discover How to Track Down HIV's Hiding Spots—A Potential Pathway to a Cure

Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.

News: Hospital Floors May Look Clean, but They're Teeming with Deadly Superbugs—Including MRSA, VRE & C. Diff

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.

How To: Make Water 'Bottles' You Can Eat

Bottled water is a rip-off. Not only is it pretty much the same stuff that comes out of your tap for free, but plastic bottles are rarely recycled and thus account for a huge amount of the waste that's overflowing our landfills. Next Up: Water Bottles You Can Eat

News: Magic Leap CEO's Tweetstorm Tries to Reframe Reactions to Latest Demo After Signs of Disappointment

Magic Leap CEO Rony Abovitz doesn't engage in tweetstorms often, but when he does, those tweets are bold, exceedingly confident, and there's usually a strong takeaway regarding what the company is or isn't doing.

News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

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...

News: How Researchers Could Use Bacteria to Determine Time of Death

When a dead body is discovered, finding out when the person died is just as important as finding out how the person died. Determining the time of death has always involved lots of complicated scientific detective work and less-than-reliable methods. However, a study by Nathan H. Lents, a molecular biologist at the John Jay College of Criminal Justice in New York, is the first of its kind to show how microbes colonize a body's ears and nose after death.
