Yellow fever, an acute viral disease, is estimated to have been responsible for 78,000 deaths in Africa in 2013 according to new research. The research also estimates that recent mass vaccination campaigns against yellow fever have led to a 27 percent decrease in the burden of yellow fever acros... Read More
Air and surface sampling techniques currently used by the US government are effective in fighting bioterrorism and potentially saving lives, a researcher finds. In 2005 and 2009, the Pentagon Force Protection Agency (PFPA) in order to simulate a deliberate attack, staged the release of a harmles... Read More
The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed, a Dartmouth C...

The EU Commission has agreed new rules to limit the spread of a deadly swine disease that has killed millions of piglets in the US.
Porcine Epidemic Diarrhoea virus (PEDv) has wiped out around 10% of the American herd in a year.
While the EU rejected an outright ban on live pig imports, it... Read More
While I was working on the “H1N-What?” post, I also knew there would soon be questions about MERS (Middle East Respiratory Syndrome), just as there were about SARS. So here are the essentials of what we know and don’t know about MERS—which has just been reported in the U.S.—as well as intriguing... Read More
We need to understand how diverse communities of microbes interact, but doing so in the gut is hard. Why not turn to a model system, where diverse microbial communities interact, but in an environment that’s easier to study? We have a long history of using model systems in biology – the mice I m...

Pathogenic fungi like Candida albicans can cause oral, skin, nail and genital infections. While exposure to pathogenic fungi is generally not life-threatening, it can be deadly to immunocompromised patients with AIDS or cancer. A variety of antifungal medications, such as triazoles and polyenes,... Read More
Caribbean health experts warned last week that they “cannot stop” a rapidly spreading mosquito-borne virus that has infected thousands and is associated with six deaths in the region.
The alert came as the Dominican Republic’s health ministry became the 15th Caribbean nation to confirm cases ... Read More
It is, says the World Health Organization, "an extraordinary event." Polio is spreading to a degree that constitutes a public health emergency.
The global drive to wipe out the virus had driven the number of polio cases down from 300,000 in the late 1980s to just 417 cases last year. The Worl... Read More
Bacteria that have no friends don’t get sad; they get weird. When E. coli cells sense fewer other bacteria around them, their DNA starts to mutate at a faster rate. That’s bad news for humans and our antibiotics. But if we can make bacteria feel less alone, we might be able to slow down their de... Read More

Life is no cake walk at the ocean floor, where carbon is scarce and light nonexistent. At least near deep ocean vents, mineral-rich water bubbles up from magma beneath the crust, providing both heat and a source of energy. In these alien environments, lithotrophs- bacteria that eat minerals ins... Read More
