A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More
The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from gen... Read More

Wesley Morovic explains his journey from a Bachelor’s degree from the University of Wisconsin to DuPont. Learn more about what he does, how he got to his position, and what you should do to get there. Read More
It is not unexpected that the contemplation of bacteria and archaea should focus so much on the nature and importance of their cell envelopes. Here, after all, is the interface between the cell's interior and the outside world. It is also what a host perceives early on when becoming infected.... Read More

How critical illness alters the microbiome, and the consequences of a sewage spill into an aquatic environment, from the TWiM team.
Dear Vincent, Elio, Michael, and Michelle,
I've just recently finished TWiM number 133 and wanted to comment about the use of the term "secondary metabolite" throughout the episode and often in the primary literature. Michael pointed out that a se... Read More
In the second of two shows recorded at the University of North Carolina in Chapel Hill, Vincent meets up with faculty members to talk about how they got into science, their research on RNA viruses, and what they would be doing if they were not scientists.

In my previous posting (Part 1), I reflected on the historical change of the new ASM governance. Here I would like to highlight some key issues that I see facing ASM and its new governance structure. This is not a prescriptive list, but rather a list of goals or, if you prefer, a straw man for ... Read More
Communication of experimental results via publishing is one of the most important steps of the scientific method; if you don’t share your results, how will knowledge within a field grow? A well-written article contextualizes the author’s data into a broader scientific landscape, which allows rea... Read More
