I had a little time to work on this illustration over the weekend. Disapproving expressions now added! It’s been fun to attempt a direct copy, and the owner has enjoyed the progress pics. It’ll be part of his display on maille making.

Here’s @tosinorababa.bsky.social & @nreddy.bsky.social showing the ways we grow bacteria in the lab to simulate conditions in an infected patient - we have models of #CysticFibrosis lung, endotracheal tube & chronic wound, all compliant with efforts to reduce & replace animals in research.

In a very interesting talk about training dogs to sniff out infection - including Pseudomonas aeruginosa in #CysticFibrosis Here’s a study link, from medicaldetectiondogs.org.uk with @janedaviescf.bsky.social & colleagues publications.ersnet.org/content/erj/5

On Sunday, Wantage will celebrate its most legendary figure – King Alfred the Great. I'll be there with plenty of other nerds, displaying the history and material culture of Wessex in Alfred's time. Full info at wantagetowncouncil.gov.uk/alfredfest-2...

@aaroncurtismicro.bsky.social adapted our ex-vivo pig lung infection model to conduct dual host-pathogen proteomics in response to Aspergillus infection - he’s a finalist in @microbiologysociety.org young microbiologist of the year #MicroSky www.tandfonline.com/doi/10.1080/...

I found the most beautiful shieldbug in the garden yesterday! Opulent purple and gold, accessorised with bold stripes. Apparently it’s a hairy shieldbug.

Aaron used cell culture medium in this first experiment, as we wanted to see what was possible re: keeping the host tissue alive. The next big step will be seeing what happens with synthetic CF mucus#MicroSky Image: PCA & clustering of pig proteins at 24-96h pi

The bull is my favourite part of this carpet page, he ended up looking so cute. Red ochre ink sketching, with egg tempera / glair mineral paints.

Yesterday, Warwick held a public festival of arts & culture. @tosinorababa.bsky.social, Erin Connelly and I had an excellent day talking about historical medicine, alchemy and the modern-day science we’re doing as part of the #Ancientbiotics collaboration. #SciComm

How did I miss this paper? @ronanmccarthy.bsky.social lab screened nosocomial bugs for plastic-degrading enzymes, reasoning that they've been selected for this ability. They found a P. aeruginosa enzyme that efficiently degrades plastic #Biofilms11 #MicroSky (Image: www.cell.com/cell-reports...
