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
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

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.

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
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
President Obama has appointed a new Presidential Commission for the Study of Bioethical Issues, replacing his predecessor's President's Council on Bioethics.

In fall 1976 the first recorded Ebola outbreak ravaged a small village in the Democratic Republic of the Congo (formerly Zaire). The virus, named for the river valley where it was found, causes a deadly hemorrhagic fever. It spread quickly via contact with blood and contaminated needles killing... Read More
Lapses in procedures aimed at fighting infections are common in ambulatory surgical centers, a study shows. The lapses include safe hygiene methods and improper handling of medications and equipment.
The study by the CDC is published in the June 9 issue of The Journal of the American Medical ... Read More
In the event of an infection, the immune system releases messenger substances. These molecules can either activate immune cells to defeat invading pathogens, or inhibit them to prevent an excessive immune reaction. For this, the immune system has to decide very quickly what mixture of activating... Read More
"Drug firms 'encouraged world health body to exaggerate swine flu threat'," screamed Britain's Daily Mail newspaper on June 4.

Any gardener has seen it happen. One plant in the backyard thrives, while its neighbor of the same species is plagued with infection. Why?
One reason may be genetic. Researchers have discovered that more resistant mouse ear cress plants have a variant of a gene known as ACD6. Plants with thi... Read More
