Scott Hultgren, Ph.D., an expert on the interactions between bacteria and human hosts, will deliver the next Flexner Discovery Lecture on Thursday, March 7. Read More

Vanderbilt investigators report new insights to the workings of calprotectin, an immune system protein that “starves” bacterial pathogens of the metal nutrients they require. Read More

Vanderbilt biochemists have discovered that the process bacteria undergo when they become drug resistant can act as a powerful tool for drug discovery. Read More

It may be possible to fight hospital-acquired pathogens like Acinetobacter baumannii by targeting the bacterium’s need for the nutrient metal zinc. Read More

Study adds evidence for infectious agents’ role in sarcoidosis, an inflammatory condition that can lead to respiratory failure and death. Read More

The stomach bug Helicobacter pylori increases forms of a protein that promote tumor development, perhaps explaining how it elevates risk for gastric cancer. Read More

The epithelial cells that line the intestines have a newly discovered mechanism for protecting us against microbes: they fire anti-bacterial "bullets" into the gut. Read More

A protein isolated from beneficial bacteria found in yogurt and dairy products could offer a new, oral therapeutic option for inflammatory bowel disorders. Read More

Vanderbilt researchers are exploring what role, if any, bacteria play in environmental diversity, with the aim of answering one of biology's most fundamental questions. Read More

Accepting and understanding natural variability is the key for engineers seeking to make nanoscale devices that are as efficient as living microorganisms. Read More

Caving expert John Hickman, who accompanies Bachmann on his underground expeditions, rappels down to the entrance of the Snail Shell Cave near Murfreesboro, Tenn Have you ever had the feeling that events beyond your control are working in your favor? That certainly seems to have been the case in the… Read More
