Helicobacter pylori infects up to 90 percent of people in the developing world and causes gastric ulcers and cancers of the gut. Now scientists have revealed a subterfuge used by the bacterium to trick stomach cells into playing along. By injecting a protein into the stomach lining that mimics a... Read More
Scientists have discovered a signaling pathway that tuberculosis bacteria use to coerce disease-fighting cells to switch allegiance and work on their behalf. Epithelial cells line the airways and other surfaces to protect and defend the body. Tuberculosis bacteria co-opt these epithelial cells i... Read More
The University of Pennsylvania and the University of Georgia have won a $14.6 million grant from the National Institute of Allergy and Infectious Diseases to expand a pathogen genomic database that serves as a resource for scientists studying infectious diseases, Penn said today.

An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. In the Proceedings of the National Academy of Sciences, researchers report progress in applying an approach to "lensless"... Read More
An article published online first and in an upcoming edition of The Lancet reports that identification of sepsis-causing bacteria using a new microarray platform is highly accurate and delivers results an average of eighteen hours faster than the current gold-standard system. It uses techniques ... Read More
Scientists studying how bacteria under stress collectively weigh and initiate different survival strategies say they have gained new insights into how humans make strategic decisions that affect their health, wealth and the fate of others in society.
Their study, published this week in the ea... Read More
A new Northwestern University study suggests that American parents should ease up on antibacterial soap and perhaps allow their little ones a romp or two in the mud --- or at least a much better acquaintance with everyday germs.
The study is the first to look at how microbial exposures early ... Read More
This year, as you may have noticed, has been one long party in honor of Charles Darwin. That’s now drawing to a close. But don’t put away your glad rags. Next year is also slated to be one long party; this time, in honor of biodiversity. Yes, 2010 is to be an international knees-up for the other... Read More
Doctors may soon be able to quickly and accurately diagnose the cause of pneumonia-like symptoms by examining the chemicals found in a patient's urine, suggests a new study led by UC Davis biochemist Carolyn Slupsky.

The first comprehensive study of pandemic H1N1 influenza from April to the end of July indicates that the pandemic may be the mildest ever, assuming that the virus doesn't mutate during the winter and come back stronger than before. The analysis suggests that the swine flu virus might directly c... Read More
The 2009 H1N1 influenza virus used a new strategy to cross from birds into humans, a warning that it has more than one trick up its sleeve to jump the species barrier and become virulent.
In a report in the journal Proceedings of the National Academy of Sciences, University of California, Ber... Read More
