The fall semester has begun, and with that we have started a new round of recordings of the Microbiology Lab Pod. Our fourth episode was recorded on August 20, and the now-familiar crew (Johan Bengtsson-Palme, Emil Burman, Haveela Kunche and Anna Abramova) has been augmented with two new master students in the lab: Sebastian Wettersten and Mahbuba Lubna Akter. This time, we discuss microbial communities of dead and alive deep-sea hydrothermal vents, look at a model system for pathogenic biofilm formation in the lungs, and check in on why patients with covid-19 commonly lose their sense of smell.
The specific papers discussed in the pod (with approximate timings) are as follows:
