"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

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

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

Community-based HIV prevention can boost testing, help reduce new infections

Communities in Africa and Thailand that worked together on HIV-prevention efforts saw not only a rise in HIV screening but a drop in new infections, according to a new study in the peer-reviewed journal The Lancet Global Health.

The U.S. National Institute of Mental Health's Project Accept —... Read More

Nibbled to Death: U.Va. Researchers Discover New Way Human Cells Are Killed

Researchers at the University of Virginia School of Medicine studying a potentially deadly parasitic infection have discovered a previously unknown way that human cells are killed, with the parasitic amoeba essentially nibbling cells to death – as a piranha might attack its prey.

Until now, r... Read More

Metallo-β-lactamase producing Acinetobacter species

Acinetobacter species are among the most common nosocomial pathogens that are notorious for multi-drug resistance. Their immense ability to acquire or upregulate antibiotic drug resistance determinants has established them as a successful pathogen, causing wide range of infections such as wound ... 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

Assortment in colony biofilms

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... 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

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

Ebola Virus: A Grim, African Reality

There’s nothing like an outbreak of Ebola virus disease to bring a small, struggling African nation to international notice. One week we couldn’t place it on a map; the next week, after Ebola virus disease strikes, we know the body count and the name of the capital and whether its airport has cl... Read More

Gut Reactions to Beneficial Bacteria

Q. When you eat yogurt or take a probiotic supplement, why aren’t the probiotic bacteria killed by stomach acids?

A. The point of consuming a probiotic supplement in a food like yogurt, a powder or a capsule is to introduce beneficial bacteria in the gut, said Dr. Christine Frissora, a gastro... Read More

While it is true that Taenia saginata tends to be benign as helminthic infestations go in humans, the same cannot be said for Taenia solium.


In both cases, ingestion of (encysted) larvae leads to enteric infestation wi... Read More

NASA To Study If Space Travel Makes Twins Biologically Different

The world’s only twin astronauts will take center stage in an upcoming NASA experiment that will analyze whether or not identical siblings remain the same biologically if one travels to outer space while the other remains on Earth.

According to the US space agency, astronaut Scott Kelly will ... Read More

The sorceress’s apprentice

ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
