I think I’d nominate The Imagined Village - they’re a music project that brings different musical traditions from immigrant cultures together with English folk music, to re-set and re-tell stories. Here’s their version of Cold Haily Rainy Night youtu.be/D8Yn5rFkaw4?...

We found the same - weak biofilms that can stand up to prep for light microscopy would completely disappear with SEM prep.

@edrybicki.bsky.social I’ll have to hunt that one out! The cryoSEM is all thanks to Chris Parmenter @uonnmrc.bsky.social and Saskia Bakker, who leads Warwick’s cryoEM facility - sadly neither are on bkuesky.

Thanks! Just checked and this locus fits into profile 7 in Table 2 upreg from day 1 to day 2, then down again by day 7 - you can find the details in the supplementary Excel file.

In the standard SEM image, aggregates of bacterial cells with no visible matrix sit on top of a network of collagen fibrils. In the cryo image, interconnected aggregates are covered with a smooth coat of matrix, and no collagen is visible - it is under the aggregates, and the only tissue structures visible are patches of elastin fibres.

If you check out my lab's recent work, you'll notice how much biofilm structure is destroyed by dehydration & vacuum during standard scanning electron microscopy. These are both images of P. aeruginosa PA14 #biofilm on pig lung tissue at 48h p.i: using cryoSEM retains the biofilm matrix. #MicroSky

This work was led by the fabulous Niamh Harrington during her PhD, and as part of it she supervised @freyaallen.bsky.social so she could contribute to the bioinformatics analysis as part of her MBio. Electron microscopy was contributed by @microberamon.bsky.social #MicroSky

The main pattern over this period was changes in expression of loci associated with central metabolism, notably sulphur metabolism - poss. reflecting a shift to anaerobic respiration, but this needs more work (& oxygen electrodes that don't shatter on the gentlest contact with cartilage 😭) #MicroSky

We previously showed increased expression of some canonical AMR determinants in the model vs. in vitro at 2 days p.i. We found antibiotic tolerance increased from 2 to 7 days p.i., but this was not associated with further increased in expression of the same genes. #MicroSky

*Knowing where to find* information relevant to your field of study is a central pillar of academic competency, and one of the skills a PhD imparts (although by no means confined to those with PhDs). Academics aren't just people who know stuff and have written stuff - they know where to find stuff.

πŸ””Seminar OpportunityπŸ””

We're looking for (self)recommendations for a Postdoc who is working in the area of AMR (any area, any discipline) to give an online seminar in May.

Reply, DM or email me, there will more opportunities in the future as well so will be good to have a list.
