For my Microbiology course at the University of Puget Sound, I decided to ask my new crop of "micronauts" what the word "microbiology" meant to them on the first day of class. Here are their answers. My wife Jennifer Quinn and I put this together using art from former students. Hopefully, thi... Read More
Dear TWIM Team,
First of all, thanks for the supremely informative and entertaining podcast. As a biologist who stumbled into my passion for microbiology almost by accident (as a student, I began my research as a herpetologist and was converted wh... 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
In the 1960’s, the microbicide triclosan, was introduced in the United States, and soon after, human weight started to increase dramatically. For some time, researchers have wondered whether triclosan could have played a role in disrupting endocrine dysfunction and contributing to the obesity ep... Read More
Although the Gram-negative bacterium Vibrio cholerae (right) is normally associated with human pathogenic disease, most V. cholerae cells spend their lives in an aquatic environment, and only a few of the many serotypes are able to cause disease. When strains acquire the right genetic makeup – s... Read More
The arrival in the US of plasmid-mediated resistance to colistin antibiotics, a last line of defense against many gram-negative bacilli, and a quorum sensing system in a eukaryote are topics of this episode hosted by Vincent, Michael, and Michele.

As we’ve seen in numerous cases in 2015, food contamination is a real issue for a number of different food types. Vegetable, meat, packaged, fresh – even pet food – we’ve seen too many examples of how bacteria can outsmart our best food safety practices. The Canadian government estimates 1 of ev... Read More
Whether you’ve Google-searched “biofilm” to learn more yourself, taken courses covering the subject, or are deeply embedded in biofilm-related research, you’ve probably encountered a model similar to the one below, which represents biofilm maturation. In the current model, a biofilm begins with ... Read More
This morning, the American Academy of Microbiology released a report, “Applications of Clinical Microbial Next-Generation Sequencing.” An event was held at the National Press Room to highlight its release. You can read more about the event here, or go here to read recommendations on NGS in a cli... Read More
Jean-Paul Latgé originally wanted to know if he could test the breath of patients with Aspergillus infections for volatile compounds produced by the fungus. His group at the Pasteur Institute in Paris thought this might be a new way of diagnosing fungal culprits like Aspergillus fumigatus that o... Read More
Scientists and science educators now recognize the value in explaining what fields don’t understand, in addition to facts supported by years of experimental data. Citizen science projects, which emphasize accessibility of scientific technologies and methods for everyone, allow people without yea... Read More

Breast milk provides an inexpensive, nutrient-filled source of food for babies. Because of this, the American Academy of Pediatrics and the WHO recommend new mothers to exclusively breast feed their babies for the first six months of life, and continue up to two years (supplemented with other fo...

Fecal transplants are increasingly being used for refractory Clostridium difficile and other gastrointestinal disorders. While fecal donors are screened for various infectious diseases, it is unclear whether viruses can in fact be transmitted during fecal transplants. Now a new study shows that ... Read More
Drug-resistant infections are becoming one of the scariest epidemics since the advent of antibiotic discovery. Although microbes like methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Klebsiella pneumoniae, and multidrug-resistant Pseudomonas aeruginosa are responsible for... Read More
The Namib Desert is different than other deserts: it has an unusual geographic feature that differentiates it from most others. This desert (map, right) is where you can find ‘fairy circles,’ or circular areas absent of growth in an already plant-scarce environment. These deadened circles are su... Read More
