When flu season arrives, you might start eyeing citrus fruit closely or washing your hands with extra diligence. You're not alone. One species of plant, Arabidopsis thaliana, also anticipates an impending infection and guards itself against it.
The secret to its success is an immune system th... Read More
A new study led by researchers at Rhode Island Hospital in collaboration with the University of Rhode Island (URI) and EpiVax. Inc, a privately owned vaccine development company in Providence, RI, has identified a potential vaccine capable of reducing colonization of Helicobacter pylori (H. pylo... Read More
Microbes have three options: They can live, they can die, or they can be dormant.
How large numbers of dormant microorganisms, which act like hibernating bears, affect the natural environments when they act as microbial seed banks is unknown, says Jay Lennon, assistant professor of microbiolo... Read More
The new vaccine was studied in rhesus macaques for a Jan. 31 report published in the journal Proceedings of the National Academy of Sciences.
“An effective dry powder vaccine would be tremendously helpful in less-developed regions where resources are limited,” says Diane Griffin, senior autho... Read More
Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered a new way to combat antibiotic resistant bacteria by using the bacteria's own genes.
For more than 50 years, antibiotics have been used to treat a variety of deadly infections and saved countless lives. Its broad int... Read More
A study published in mBio this week highlights a novel approach to developing new antibiotics for tuberculosis and other infections using high-throughput bioinformatics. Lamichhane et al. generated and genotyped over 5,000 strains of M. tuberculosis and used statistical analysis to find putativ... Read More
A team of scientists from around the globe have found that gut bacteria may influence mammalian brain development and adult behavior. The study is published in the scientific journal PNAS, and is the result of an ongoing collaboration between scientists at Karolinska Institutet in Sweden and the... Read More
A row has broken out in France over whether 15- and 16-year-olds should be allowed to create transgenic Escherichia coli bacteria in the classroom.
Practical experiments in which students learn how to use plasmids to alter the DNA of the bacteria have been under way for 17 and 18-year-olds in... Read More
A new study has suggested that the abundance or scarcity of certain types of bacteria in the gut may also help predict susceptibility to non-alcoholic fatty liver.
In a metagenomic analysis of the microbial communities living in the intestinal tracts of 15 female patients participating in a s... Read More
On Monday, in a Manhattan town house that once belonged to polio’s most famous victim, Franklin D. Roosevelt, Bill Gates made an appeal for one more big push to wipe out world polio.

Frederick Hayden, Professor of Medicine and Pathology, University of Virginia School of Medicine, U.K., has focused on the use of antiviral agents to prevent and treat respiratory viral infections. I discussed the use of antiviral drugs to treat influenza with Dr. Hayden during ICAAC Boston 2010... Read More
Researchers seuquence more than 200 strains of streptococcus pneumoniae and reveal ways that the mircobe evades attempts to defeat it. Findings show how the microbe swaps chunks of DNA with other strains, allowing it to evolve defenses against antibiotics and vaccines. Emily Singer of MIT Techn... Read More
My virology course at Columbia University, Biology W3310, has begun. This course, which I taught for the first time in 2009, is aimed at advanced undergraduates and will be taught at the Morningside Campus of Columbia University. Read on to learn how to access all the course materials, including... Read More
Most people would probably prefer if traces of dairy cows' vaccinations don't show up in their milk, but one research team is looking into deliberately adding antibodies to milk as a way to help malnourished children in developing countries.
