Current research suggests that viral polymerase may provide a new therapeutic target for host-adapted avian influenza. The related report by Gabriel et al, "Spread of Infection and Lymphocyte Depletion in Mice Depends on Polymerase of Influenza Virus" appears in the September 2009 issue of the A... 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
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
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...

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
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
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
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
Wash your hands. That’s a common mantra — and a worthy one — as the H1N1 flu continues to spread around the globe.
But all the hand-washing in the world may not be a match for the germs and viruses lurking on household surfaces.
“There is a big appreciation for influenza that you can get ... Read More
