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
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
University of Michigan microbiologist Pat Schloss, Ph.D., describes latest findings from Human Microbiome Project. Based on their findings in today’s Nature, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that’s the result of life his... Read More
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
For nearly a decade, Brooklyn-based artist, photographer, and Guggenheim Fellow Rachel Sussman has been traveling the globe to discover and document its oldest organisms — living things over 2,000 years of age. Her breathtaking photographs and illuminating essays are now collected in The Oldest ... Read More
A mechanism that may help explain the severe forms of schistosomiasis, or snail fever, has been discovered by researchers. Schistosomiasis is one of the most prevalent parasitic diseases in the world. The study in mice may also offer targets for intervention and amelioration of the disease. Alth... Read More
As an educator and researcher at a small liberal arts institution, my success is measured (to me) in watching former students from my classroom and laboratory go on to do great things after graduation. Here, I share some great information about (and by) a former student of mine, Franny Gilman, ... Read More
Nepal is a developing country, where there is more craziness increasing day by day in the field of microbiology.Microbes are remarkably diverse organisms. They live in habitats throughout the world: in fresh and salt water, on land, in the air, and on or inside other organisms. we can see smiley... Read More

In 2004, the rebel geneticist Craig Venter took a sailing trip to Bermuda and, unable to resist doing a little research on the side, hauled up 50 gallons of the Sargasso Sea and began trawling it for DNA. It looked for all the world like cold, sterile saltwater, but Mr. Venter h... Read More

In order to survive, organisms produce small molecules known as ‘primary metabolites’ which help it to grow, develop and reproduce. Examples include nucleic acid used to make DNA, amino acids to make proteins, and simple sugars. Once the organism is established it will often start to produce ‘se... Read More
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
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
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.
