The soft flesh of a banana provides a ready source of DNA. Using a few simple purification steps in a classroom setting, students can yield loads of crudely prepared DNA. To begin, the banana is mashed in a detergent/salt solution to lyse the cellular and nuclear membranes. Cellular lysate is st... Read More
Scientists at UC Santa Barbara have discovered a potential new drug delivery system. The finding is a biological mechanism for delivery of nanoparticles into tissue. The results are published in the Proceedings of the National Academy of Sciences.
"This work is important because when giving a... Read More

Dr Adam Rutherford continues the extraordinary story of the scientific quest to discover the secrets of the cell and of life itself.
He explains how it is possible to turn ageing bacteria into diesel which is capable of powerin... Read More
Developments in genetics are now making it possible to invite custom-engineered symbiotic creatures into our bodies to help perform the functions we can't. In two separate developments, scientists have created a strain of bacteria that stimulates insulin production in the stomach of diabetic mic... Read More
Researchers at the University of Illinois at Chicago School of Public Health have received a grant from the U.S. Department of Agriculture to educate AIDS patients on food safety.
The three-year, $600,000 award will be used to develop a better way to disseminate information to AIDS patients w... Read More

Many leisure activities, however enjoyable they may be, expose us to a growing list of pathogenic microbes, some new and many increasingly resistant to current therapies. The latest edition of the ASM Press book Infections of Leisure, Fourth Edition continues to compile information on leisure-as... Read More
In a fundamental study of how to control protein shape, a UW-Madison research team has created a set of peptide-like molecules that successfully blocked HIV infection of human cells in laboratory experiments.
"By interacting with a piece of a crucial HIV protein called gp41, the synthetic mol... Read More
A new study suggests that when compared to conventionally raised beef cattle, organic and natural production systems do not impact antibiotic susceptibility of Escherichia coli O157:H7. This discovery emphasizes that although popular for their suggested health benefit, little is actually known... Read More
A brief video history of Robert Koch, one of the founding fathers of Bacteriology and Microbiology who was awarded the Nobel Prize in Medicine for his contributions and discoveries on Tuberculosis.
An article by Alan Derman, Project Scientist in Joe Pogliano’s lab at the University of California at San Diego, published on the Small Things Considered blog presents a point-by-point analysis of a paper "Quantitative genome-scale analysis of protein localization in an asymmetric bacterium" pub...

According to the CDC, deaths from this year's flu season could be double the average. Moreover, the pattern of infection is different than that of the regular flu; children and young adults are more at risk and H1N1 spreads easily. This three minute video gives an overview of the CDC's latest an... Read More
From avian flu to cholera, infectious diseases may not be able to hide for long. Some researchers have their sights trained on predicting their every move with detailed satellite data
Rather than searching for weird weather or enemy missiles, some satellites are helping researchers to track—a... Read More
A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley.
Findings from the study, which will appear June 29 ... Read More
Researchers at Penn State University have engineered a microbial fuel cell which turns dirty salt water into electricity and drinkable water.
The researchers start with a cup full of water from a pond or other natural source. Among the millions of microbes in the sample, some of the bacteria... Read More
Lichens are the classic example of a symbiotic relationship. Both the fungal and photobiont components of the lichen benefit from the relationship and often are unable to survive without each other. Recent research by Dr. Robert Lücking (The Field Museum, Chicago), Dr. James Lawrey (George Mason... Read More

Stanley Falkow, Professor Microbiology and Immunology, Geographic Medicine, Infectious Diseases, Stanford University School of Medicine, presents the second part of a lecture on host-pathogen interaction. This one focuses on H. pylori (the ulcer bacterium) and the story behind its discovery by A... Read More
Stanley Falkow, Professor Microbiology and Immunology; Geographic Medicine; Infectious Diseases, Stanford University School of Medicine, presents a lecture on host-pathogen interaction.
"Ninety percent of the cells humans carry are microbes. Only a few of the bacteria we encounter are pathoge... Read More
This lecture covers the biochemical basis of actin-based motility (focusing on the pathogen Listeria as a model system for this process), the biophysical mechanism of polymerization-based force generation, and an evolutionary perspective of cell shape in prokaryotes and eukaryotes. The first par... Read More
