The discovery of antibiotics (also referred to as antimicrobials) is perhaps the most revolutionary outcome in the medical sciences during the twentieth century, and has allowed medical practitioners to treat a wide range of bacterial infections; and therefore, antimicrobials are the most common...

Pneumonia remains a serious worldwide problem, especially among the young, elderly, and immunocompromised. Over 900,000 children die each year due to the disease, and respiratory syncytial virus (RSV) is the most common viral cause (Streptococcus pneumoniae and Haemophilus influenzae type b bein...

Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
In this month's episode of the science show This Week in Evolution, Nels and I discuss the evolution of butterfly wing patterns. In this study of Amazonian butterflies, the authors show that distinct patterns are a consequence of enhancer shuffling. Enhancers are DNA sequences that control trans... Read More

Scientists from the University of Queensland and a biotechnology company discovered a new class of antibiotics, which is a kind of synthetic sugar. And the new antibiotics can significantly decrease the drug resistance caused by bacteria, and kill them. These new antibiotics can be a powerful dr... Read More
So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More
Host: Jeff Fox with special guest, Jon Telling.
Jon Telling of Bristol University in Bristol, United Kingdom talks with Jeff Fox about his findings suggesting that the grinding of glaciers over rocks can liberate hydrogen, which, in turn, drives the growth of methanogens within microb... Read More
Did you ever wonder what different virus infections you have had in your lifetime? Now you can find out with just a drop of your blood and about $25.
Immune defense systems of many hosts produce antibodies in response to virus infections. These large proteins, which are generally virus specif... Read More
I have worked on poliovirus for over thirty-six years, first as a posdoctoral fellow with David Baltimore in 1979, and then in my laboratory at Columbia University. The end of that research commences this year with the destruction of my stocks of polioviruses. Read More
Veintinueve profesores e investigadores de 20 universidades y centros de investigación van a colaborar para impartir el primer curso mundial online gratuito vía Twitter sobre microbiología. La iniciativa está coordinada y organizada por el grupo de Docencia y Difusión de la Microbiología de la S... Read More
“Stefano, you seem like a smart person. Can I ask you why you decided to take a job with a scientific society?” I had just helped myself to a slice of a very sharp Stilton cheese, after a wonderful dinner supported by wonderful wine. All of a sudden the Stilton seemed even sharper. The question ... Read More
A common denizen of the undergraduate microbiology laboratory, Serratia marcescens is well known for the production of a bright red pigment, prodigiosin. Prodigiosin has been investigated over many years for its possible antimicrobial, antifungal, and even antitumor effects. Still, the relevan... Read More
Viruses that are harmless to humans might help fight the deadly scourge of bacteria that can't be treated with antibiotics, researchers say.
These viruses could be used in hand santizers, and to treat exposed surfaces in hospitals, which are hotbeds of antibiotic resistance, the researchers n... Read More
If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More
Because of its simplicity and the rapid time-to-result turnaround, gram staining plays an important role in clinical microbiology. Learning the cell structure helps eliminate potential disease etiologies: learning an isolate is a gram-negative rod doesn’t tell you what the diagnosis is, but it h... Read More
How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More
A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmun... Read More
Single-celled organisms called bacterioplankton spend their lives drifting in open ocean, visible to the naked eye only en masse. But don't be fooled by their slight size: These minuscule critters play a hefty role in the carbon cycle. Heterotrophic microbes, by some estimates, process half of t... Read More
