"Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy" Infographic

The American Academy of Microbiology has just released a new report, "Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy," and along with it, an infographic, that summarizes the main points of the report. The full report can be found here: http://bit.ly/1lk346I, and a link t... Read More

What Happens to Bacteria in Space?

In the otherwise barren space 220 miles above Earth's surface, a capsule of life-sustaining oxygen and water orbits at 17,000 miles per hour. You might know this capsule as the International Space Station (ISS), currently home to six humans—and untold billions of bacteria. Microbes have always f... Read More

Stockpiles of Roche Tamiflu drug are waste of money, review finds

Researchers who have fought for years to get full data on Roche's flu medicine Tamiflu said on Thursday that governments who stockpile it are wasting billions of dollars on a drug whose effectiveness is in doubt.

In a review of trial data on Tamiflu, and on GlaxoSmithKline's flu drug Relenza,... Read More

Predicting the virulence of MRSA from its genome sequence

Microbial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen’s evolutionary trajectory. Toxicity, the ability to destroy host cell membranes, and adhesion, the ability to adhere to human tissues, are the major virulence factors of many bacterial pathogens... Read More

Genetic Defect May Confer Resistance to Certain Viral Infections

A National Institutes of Health (NIH) study reports that a rare genetic disease, while depleting patients of infection-fighting antibodies, may actually protect them from certain severe or recurrent viral infections. Researchers found that HIV and influenza viruses replicate in the cells of peop... Read More

Phage 'cocktail' wipes out 99 percent of E. coli in meat, spinach

Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.

An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More

Yellowstone Caldera, Wyoming

Bacterial mats, golden brown in color, seen at the outer edges of Chromatic Pools. The blue water in the center is the hottest water at ~199 F and cooling to ambient the farther you get from the center. Cyanobacteria grow around 163 F or lower. Read More

New research shows how pathogenic E. coli O157:H7 binds to fresh vegetables

Food-poisoning outbreaks linked to disease-causing strains of the bacterium Escherichia coli are normally associated with tainted meat products. However, between 20-30% of these are caused by people eating contaminated vegetables, as was seen in the 2011 outbreak in Europe that caused 53 deaths.... Read More

By Chance and Necessity: The Role of the Cytoskeleton in the Genesis of Eukaryotes

One of the most exciting and enduring obscurities of biology lies in the early stages of the evolution of “our” eukaryotic cells (Figure 1). The endosymbiotic theory accounts well for the present existence of the mitochondrial and chloroplast organelles of eukaryotes. Although there is evidence ... Read More

Life-style determines gut microbes

The gut microbiota is responsible for many aspects of human health and nutrition, but most studies have focused on “western” populations. An international collaboration of researchers, including researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has for th... Read More

Nanocrystalline cellulose modified into an efficient viral inhibitor

Researchers have succeeded in creating a surface on nano-sized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them. The results can prove useful in the development of antiviral ointments and surfaces, for instance.

There are many viral diseas... Read More

Evolution of whooping cough bacterium could reduce vaccine effectiveness

The bacterium that causes whooping cough, Bordetella pertussis, has changed – most likely in response to the vaccine used to prevent the disease – with a possible reduced effectiveness of the vaccine as a result, a new study shows.

A UNSW-led team of researchers analysed strains of Bordetella... Read More

Microbial Misadventures: A Malaria Outbreak Without Mosquitoes

Shout “fire” in a crowded room and watch the occupants fly for the exits. Speak the word “malaria” and watch as all within earshot reach for the nearest can of DEET. The incontrovertible fact of malaria’s relationship with mosquitos is one that has been known since Sir Ronald Ross discovered th... Read More

Immune cell ‘defenders’ could beat invading bacteria

An international team of scientists has identified the precise biochemical key that wakes up the body’s immune cells and sends them into action against invading bacteria and fungi.
The patented work, published in Nature today, provides the starting point to understanding our first line of defen... Read More

How Flesh-Eating Strep Bacteria Evolved into an Epidemic

Bacteria aren’t kind enough to leave behind a fossil record (save for cyanobacteria), but they’re evolving fast. Really fast. Their short life cycles mean that generations come rapid-fire, adapting through natural selection into the monster pathogens that are currently shrugging off our finest a... Read More

Cordyceps: attack of the killer fungi

The video shows an ant that is infected with a fungus called Ophiocordyceps unilateralis, which has both infiltrated and commandeered its body. While it devours the ant alive, it also sends its zombified host scurrying up a plant stem. The ant walks along the underside of a leaf and vigorously l... Read More

Microgravity research helping to understand the fungi within

(Phys.org) —You may not recognize it by name, but if you have ever had a child with a diaper rash, that child was likely a host to Candida albicans (C. albicans). This unwelcome "guest" can be hard to control, as it can potentially lead to serious illness in humans with weakened immune systems. ... Read More
