When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
Jeff Fox, Current Topics and Features Editor of Microbe Magazine, talks with Harald Huber of the Johann Wolfgang Goethe University in Frankfurt, Germany. Huber and his collaborators have looked at the archaeon Ignicoccus hospitalis and found a very unusual cellular envelope architecture, un... Read More
Medical scientists in France have seen a recent rise in cases of meningitis C caused by a virulent substrain of bacteria whose emergence in other European countries led health authorities to introduce routine vaccination against the disease. Reporting this month online in The Journal of Infectio... Read More

The selenium clock is ticking for mountaintop mining companies, as the West Virginia Department of Environmental Protection prepares to crack down with water quality standards that producers have argued in the past are too expensive to meet.
But scientists at the West Virginia University Inst... Read More
Two Canadian researchers will be keeping a close eye on what hundreds of thousands of soccer fans take to the World Cup in South Africa _ and what they potentially bring home.
Dr. Kamran Khan, an infectious disease physician and scientist at St. Michael's Hospital in Toronto, and Dr. John Bro... Read More
Better understanding how the flu virus replicates and evolves to infect new hosts will help scientists find new ways to fight the flu. One option is the development of therapies that take advantage of the new findings by promoting mutagenesis -- treatments designed to generate increased mutation... Read More
Cancers of the neck and throat are much less likely to be fatal if they are caused by the human papilloma virus (HPV) rather than alcohol and smoking, researchers reported Monday. But if the tumor is caused by HPV and the patient also smokes, survival is significantly impaired, they found.
Th... Read More
Salmonellosis linked to Subway restaurants continues to plague the
state line with 2 cases now reported in Winnebago County. Those who
got sick ate at a Subway in Machesney Park. That now brings the total
to 60 cases of salmonellosis related to this outbreak in Illinois.

Synthetic biology hit the headlines when Craig Venter recently announced the creation of Synthia – the first organism with a computer as a parent.
JCVI-syn1.0, as the artificial microbe is officially known, will become a poster child for synthetic biology. But it was created from known geneti... Read More
This is spelunking with a twist. This is academic spelunking that is uncovering answers to questions. It is cave exploration that is helping sharpen the skills of tomorrow’s microbiologists.
Welcome to Todd Sandrin’s classroom. The associate director of the New College Division of Mathematica... Read More
While an out-of-control gusher deep in the Gulf of Mexico fouls beaches and chokes marshland habitat, another threat could be growing below the oil-slicked surface.
The nation’s worst oil spill could worsen and expand the oxygen-starved region of the Gulf labeled “the dead zone” for its inhos... Read More
Since it's 1st recorded outbreak (1976) in the Democratic Republic of the Congo's Ebola River Valley, the Ebola virus has been known - and feared - for good reason.
Why, you may ask?
Ebola hemorrhagic fever is potentially lethal and encompasses a range of symptoms including fever, vom... Read More
Saints preserve us from this one. A highly contagious hemorrhagic fever, Marburg is less well known that it's cousin Ebola, (they're both members of the deeply troublesome Filovirus family) but no less deadly.
Scientists are reporting the first evidence that a plastic antibody -- an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances -- works in the bloodstream of a living animal. The discovery, they suggest in a report in th... Read More
E. coli uses its signal recognition particle (SRP) system in membrane protein biogenesis, but there has been some question about its other possible roles. A new paper just released by mBio reveals E. coli’s SRP is also capable of regulating membrane protein synthesis. Read More
President Obama has appointed a new Presidential Commission for the Study of Bioethical Issues, replacing his predecessor's President's Council on Bioethics. Like the previous entity and similar ones before it, the group will advise the president on a wide range of difficult, controversial scien... Read More
