Ambulances are scarce in areas of west Africa roiled by the Ebola outbreak, so when ill patients and their families need to go to the clinic they often turn to the next best thing—a motorcycle taxi. An ill passenger will wrap her arms around the driver’s waist and away they will go—sometimes dri... Read More
A vaccine developed by an international team of scientists led by the University of Pittsburgh School of Medicine successfully protects mice against a contagious and deadly virus spreading across the Middle East. The vaccine is a promising candidate for immunizing camels, thought to be the sourc... Read More
Summer's almost gone. Imagine you're strolling along the shores of a lake enjoying nature's colors during sunset. Sparkle catches your eyes where the lake languidly laps against the shore.

During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More
After battling blood cancer for 10 years, Stacy Erholtz has no signs of the disease, thanks to an experimental treatment that used an engineered version of the measles virus.
Now, a year after finishing her treatment, the 50-year-old mother of three is transitioning from patient to advocate, ... Read More
At the end of a recent “Medical Microbiology” class taught by Dr. Sheldon Campbell, students clapped, cheered heartily, and stomped their feet on the floor. A couple of them even shouted “Encore!”
It’s not quite the reaction one would expect from medical students who just spent 45 minutes lea... Read More
Ah, endosymbiosis and the origin of eukaryotic cells… Wasn't this one of the grandest of all the grand events in Biology? In its ability to boggle the mind, it comes in second only to the origin of life. This, one of the most decisive events in evolution, had a unique character. Instead of new t... Read More
Extended stays in hospital appeared to increase the risk of infection with a multidrug-resistant Gram-negative pathogen, researchers said.
In a single-center study, the risk of such infection rose by 1% for every day in hospital, according to Tonya Smith, PharmD, of the University of Utah.

You know those foods and pills that promise to supply your body with "good bacteria?"
They may or may not make you healthier, but some of these "probiotics" do, in fact, appear to be effective in chickens. Poultry companies are turning to probiotics as an alternative to antibiotics, which hav... Read More
Micrococcus bacteria thrive on the open-air lattice of synthetic fibers--where they sit chomping on the fatty acids in our sweat, turning them into shorter, stinkier molecules. Christopher Intagliata reports.
