A potentially life-threatening gastrointestinal infection is more common than previously estimated, federal health officials reported Wednesday.
The infection, caused by a bacterium known as Clostridium difficile, or C-diff, causes nearly 500,000 illnesses in the United States each year and k... Read More
When Terrance Williams was 21, he met a man in Syracuse, and the two became friends. Some weeks later, they became sexually involved. Williams and this partner—who, in court papers, is referred to only as “the victim”—used protection in their relationship, at first. But one night, Williams’s par... Read More
Tiny parasitic hookworms infect nearly half a billion people worldwide, almost exclusively in developing countries. Researchers say sequencing the genome of a particular species could help develop more effective drugs.
Other hookworm species cause more disease among humans, but Ancylostoma ce... Read More

Caring for People Infected with Ebola: Stories from the Frontlines
Narrative Inquiry in Bioethics will publish a collection of personal stories from individuals who have been at the frontlines of healthcare for Ebola patients—whether as healthcare workers, family caregivers,... Read More
In a recent study, scientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), demonstrate for the first time that ocean acidification could have negative impacts on diatoms in the Southern Ocean. In laboratory tests they were able to observe that under chan... Read More
The ancestors of a large family of parasites—including those that cause malaria—were equipped to become parasites much earlier in their lineage than previously assumed, according to University of British Columbia (UBC) research.
The work, published in PNAS, traces the emergence of parasitism ... Read More
A dangerous, often deadly, type of bacteria that lives in soil and water has been released from a high-security laboratory at the Tulane National Primate Research Center in Louisiana. Officials say there is no risk to the public. Yet despite weeks of investigation by multiple federal and state a... Read More
A mysterious illness that seems to have killed a farmer in Kansas has led to the discovery of a new virus last week: the Bourbon virus.
The farmer had been working on his field last spring when he got several tick bites, including one that appeared to be attached to his shoulder. A few days l... Read More
An experimental compound empowers an enzyme to help process acetaldehyde, a toxic metabolite of alcohol, according to new research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, now online in the Proceedings of the National Academy of Sciences (PNAS), ... Read More
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus. One such recombinant variant observed in patients in Cuba appears to be much ... Read More
Mycorrhizal fungi live in the roots of host plants, where they exchange sugars that plants produce by photosynthesis for mineral nutrients that fungi absorb from the soil. They include some of the most conspicuous forest mushrooms, including the iconic, flaming red “fly agaric,” Amanita muscaria... Read More
Unidentified soil microbes on SDA plates; most colonies are producing compounds (droplets can be seen on top of the colonies; possibly antibiotic producers). This picture was taken by me, Kaitlynn Fenley. The plate is from the class that I am a teaching assistant for at Louisiana State Universit... Read More
You must have heard it said that no one is indispensable to an institution. Maybe so, but such truths come in degrees. Every so often someone comes along who makes a genuine difference in how an organization functions. I turn here to Michael Goldberg, who thirty years ago began a most distinguis... Read More
Seth Mnookin, an assistant professor of science writing and associate director of MIT's Graduate Program in Science Writing, is the author of "The Panic Virus: The True Story Behind the Vaccine-Autism Controversy", an acclaimed book that examines how inaccurate scientific reports linking vaccine...

The human body doesn’t like outsiders. When a foreign pathogen or substance, say an unwanted virus, finds its way into our blood streams we produce antibodies that the neutralize the threat. These “Y”-shaped proteins are made by a class of white blood cells called plasma cells and bind to molecu... Read More
A new paper-based platform has been created for conducting a wide range of complex medical diagnostics. The key development was the invention of fluid actuated valves embedded in the paper that allow for sequential manipulation of sample fluids and multiple reagents in a controlled manner to per...

Potentially toxic microbes which pose a threat to our drinking water have undergone a dramatic population explosion over the last 200 years as a result of pollution, research involving experts from The University of Nottingham has found. The study, published in the journal Ecology Letters, looke... Read More
This is a Tease Prep stain of the Fungal Rhizopus with Lactophenol Blue. It is seen under a microscopy at total magnification of 1000x. As shown there are pseudohyphae with conidia formed around the cells. It was the first tease prep stain that clearly shows the artistry of the fungal structure.... Read More
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based descriptio... Read More
