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
The body's appendix has long been thought of as nothing more than a worthless evolutionary artifact, good for nothing save a potentially lethal case of inflammation.
Now researchers suggest the appendix is a lot more than a useless remnant. Not only was it recently proposed to actually posses... Read More
An ocean of clean energy pours from the sky. We could forget about nonrenewable climate-altering sources, like gas, oil and coal, if we could fill the tank or power our homes with a sunbeam. Current solar technologies aren't quite up to that task. Conventional solar panels are inefficient; elec... Read More
One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More
The Hygiene Council, an international initiative based out of the UK, has produced a short CGI/computer animation on how disinfectants kill bacteria and viruses. The animation is superb and in there is no corporate branding in the piece which makes it an excellent resource for young students.

Researchers at Duke University Medical Center may have a new way to stop and even prevent the urinary tract infections (UTIs) that plague more than a third of all adults, some of them repeatedly.
The researchers have discovered how cells within the bladder are able to sense the presence of E.... Read More
The newest revolution in microbiology testing walks on four legs and says "baa."
It's the hair sheep, a less-hirsute version of the familiar woolly barnyard resident. A new study from the Stanford University School of Medicine, which is to be published July 3 in PLoS ONE, finds that not only ... Read More
A cellular molecule that not only can sense two common respiratory viruses but also can direct cells to mount a defence has been identified by microbiologists at The University of Texas Health Science Centre at San Antonio.
The finding, published online yesterday by the journal Nature Immunol... Read More
The Q Microbe, found in the soil near a Massachusetts reservoir, can produce unprecedented amounts of ethanol in a single step. Supported by a company devoted to its process and improvement, it could lead the way to commercial production of cellulosic ethanol and the achievement of renewable fue... Read More
Hosts : Read More
Viruses and bacteria often act as parasites, infecting a host, reproducing at its expense and causing disease and death. But not always - sometimes, their infections are positively beneficial and on rare occasions, they can actually defend their hosts from parasitism rather than playing the role... Read More
