In the very first episode of the Bengtsson-Palme lab podcast, a crew consisting of Johan Bengtsson-Palme, Emil Burman, Haveela Kunche and Anna Abramova discusses the origin of the novel coronavirus, interactions between influenza and the respiratory tract microbiome, resistant bacteria in glaciers, pathway analysis methods, a new genus of bacteria discovered in Gothenburg, as well as life in research during a global pandemic.

Here’s some updates on my Spring schedule.
On March 19, I will be presenting the EMBARK program and what we aim to achieve at a conference organised by the Swedish Medical Products Agency called NordicMappingAMR. The event will feature an overview of existing monitoring of antibiotics and antibiotic resistant bacteria in the environment. The conference aims to present the results from this survey, to listen to experts in the field and to discuss possible progress. It takes place in Uppsala. For any further questions, contact Kia Salin at NordicMappingAMR@lakemedelsverket.se
Then on May 18 to 20 I will participate in the 7th Microbiome & Probiotics R&D and Business Collaboration Forum in Rotterdam. This industry/academia cross-over event focuses on cutting-edge microbiome and probiotics research, and challenges and opportunities in moving research towards commercialisation. I will talk on the work we do on deciphering genetic mechanisms behind microbial interactions in microbiomes on May 20.
And finally, I also want to bring the attention to that my collaborator Erik Kristiansson has an open PhD position in his lab. The position is funded by the Environmental Dimensions of Antibiotic Resistance (EDAR) research project, aiming to describe the environmental role in the development and promotion of antibiotic resistance. The focus of the PhD position will be on analysis of large-scale data, with special emphasis on the identification of new forms of resistance genes. The project also includes phylogenetic analysis and development of methods for assessment of gene evolution. More info can be found here.
A random sample of things from this week’s scientific news I think are worth sharing:
Britain is apparently shutting down many of its climate change outreach efforts. I find this very saddening, and see it as an indication of our extreme short-sightedness. We need to put more effort and funding into preserving the environment – not less. In addition, the economic benefits of taking care of the nature around us will probably be much larger than the small sums we save in the short term by not doing anything. We clearly need better incentives to look beyond the next budget and the next election.
The editorial of Nature Reviews Microbiology points the torch on the need for research within basic microbiology, pointing out that “the functions of many genes in the genomes of even the best studied organisms, such as Escherichia coli and Bacillus subtilis, remain unknown. Often these genes do not resemble other, characterized, genes in the databases, allowing for the possibility that interesting new pathways remain to be discovered. (…) if we want to understand how life works at the molecular level, it is crucial to continue and expand basic microbiology research.” I would like to add that a more complete understanding of at least one model organism would drastically increase the accuracy of genome (and metagenome) annotation in new sequencing projects, which today is patchy, to say the least.
