A double stranded RNA (dsRNA) viral genome, introduced into a host cell, is met by formidable host defenses. The very presence of dsRNA in a eukaryotic or prokaryotic cell announces a viral infection and elicits effective responses, ranging from silencing of the viral mRNAs to apoptosis. Despite...

Scientists have identified an unusual species of pathogenic algae that causes human skin infections, described in a new study in the International Journal of Systematic and Evolutionary Microbiology. The finding should improve our understanding of how rare species of algae are sometimes able to ... Read More
We've over-fished & polluted their habitats, scrambling the species to a point where you have to filet these poor creatures just know which restroom they use! Now one of our parasites is compromising their love lives - I'd say our finny friends here have a very justified bone to pick with human... Read More
The first human clinical trials have started on a new drug developed to treat infections caused by the hepatitis C virus. The medication, taken orally, was first prepared at the Welsh School of Pharmacy at Cardiff University in 2008. Laboratory tests showed it killed 90% of the virus at very low... Read More
Of all the things that might control the onset of disease epidemics in Michigan lakes, the shape of the lakes' bottoms might seem unlikely. But that is precisely the case, and a new BioScience report by scientists from Indiana University Bloomington and four other institutions explains why.

Scientists in Finland have discovered that cheese can help preserve and enhance the immune system of the elderly by acting as a carrier for probiotic bacteria. The research, published in FEMS Immunology & Medical Microbiology, reveals that daily consumption of probiotic cheese helps to tackle a... Read More
The World Health Organisation on Wednesday advised travellers to South Africa to take precautions against insect bites and contact with raw meat, after an outbreak of Rift Valley fever killed 18 people.
"WHO advises no international travel restriction to or from South Africa." the agency said... Read More
Biological differences between the sexes could be a significant predictor of responses to vaccines, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They examined published data from numerous adult and child vaccine trials and found that sex is a fundamental, but ... Read More
The University of Wisconsin-Madison has revoked a scientist's laboratory privileges for five years and paid a $40,000 sanction over unauthorized experiments involving Brucella, a bacterium that can infect cattle and humans and is highly regulated by the federal government. Read More
On 11 May 2010 Bernhard-Nocht-Institute for Tropical Medicine in Germany reported that additional laboratory analyses conducted both in Germany and South Africa on the German tourist who was preliminarily diagnosed with Rift Valley Fever (RVF) following her return from South Africa, was in-fact ...

Trillions of bacteria might help clean up the Gulf oil spill, a specialized company reports.
Osprey Biotechnics, Inc., a pioneer in breeding beneficial bacteria, says it estimates that 55 gallons of the product it calls Munox would treat 36.5 square miles of Gulf waters. Slightly more than 10... Read More
Microbiologists at UT Southwestern Medical Center, working with the Department of Agriculture, have identified a potential target in cattle that could be exploited to help prevent outbreaks of food-borne illnesses caused by a nasty strain of Escherichia coli.
In the study, available online an... Read More
As the recall of tainted romaine lettuce expands, many plates could be devoid of the crisp veggie in an effort to stay healthy. That might be a good idea, according to experts who say that washing produce, even very carefully, may not remove all the bacteria present. Read More
Scientists are reporting success in a first attempt to silence the biochemical conversations that disease-causing bacteria use to marshal their forces and cause infections. In a study in ACS' monthly journal, Biomacromolecules, they describe use of specially designed plastic-like materials to so... Read More
Assistant architecture professor Ginger Krieg Dosier recently unveiled a new breed of biologically “grown” bricks that are durable, sustainably manufactured, and easily produced from readily available materials. Called “Better Bricks,” the building material can be “grown” from sand, common bact... Read More
Atrazine, watch out: There's a killer from the future tracking you down.
Scientists working in Georgia have engineered a common bacteria that will, in the lab, detect and seek out atrazine, a controversial herbicide sprayed over cornfields and sugar plantations across the United States.
An... Read More
With an oil spill onslaught headed for Gulf shores, you might wonder — whatever happened to those laboratory miracle oil-eating microbes for an instant clean-up?
"They don't exist," says microbiologist Ronald Atlas of the University of Louisville. "They only work in a lab flask. They have nev... Read More
An international team led by a University of Cincinnati (UC) researcher has shown how a bacterial community evolves to survive hostile host defenses in the body.
The team, led by Malak Kotb, PhD, chair of UC's of molecular genetics, biochemistry and microbiology department, analyzed the evolu... Read More
Here's a great mother's day song from a biologist's perspective. Musically it is similar to a They Might Be Giants song. Enjoy. Read More
Shoppers who go to the drug store to fill their Plavix prescriptions or pick up a bottle of prenatal vitamins may soon find themselves reconsidering these mundane purchases.
The reason? A new genetic testing kit that will hit the shelves of select Walgreens stores later this month. The test ... Read More
