A colleague received proofs of an accepted manuscript, and the "proofing process" clearly involved running the text through ChatGPT. Their voice has been erased, and errors introduced. This is from a supposedly reputable publisher. Anyone else been put through this particular form of hell? #MicroSky

Direct single-molecule detection and super-resolution imaging with a low-cost portable smartphone-based microscope - Nature Communications

Loretan and colleagues present a low-cost smartphone-based microscope capable of detecting single-molecule fluorescence. This approach opens doors to personalised and widely distributed applications in diagnostics, biosensing, and science education.

Glorious start of the day in Amsterdam!
Looking forward to meeting the scientists in EU COST Action 🧫🦠#Biofilm Regulatory Toolbox today and start discussions on how to progress #standards #methods aiming to ultimately develop #regulatory guidance

Robert F Kennedy Jr. famously advocates drinking raw milk and promotes its benefits. But how safe is unpasteurised milk? Nicola Holden and Gil Domingue, who sit on AMI’s Food Security Scientific Advisory Group, take a deep dive into the science. www.the-microbiologist.com/opinion/safe...

Lots of integrative plasmids are linear. Streptomyces Ecoli shuttle plasmids (circular, often low cooy) allow cloning in Ecoli before moving into Streptomyces

Some Streptomyces plasmids can be huge eg pSCL4 is 1.8Mb!

The Sequence of a 1.8-Mb Bacterial Linear Plasmid Reveals a Rich Evolutionary Reservoir of Secondary Metabolic Pathways

Abstract. Plasmids are mobile genetic elements that play a key role in the evolution of bacteria by mediating genome plasticity and lateral transfer of use

Streptomyces is not suitable for chemical or electro-transformation methods

Yeah, integrating plasmids can be quite big indeed. If they contain a Tra element than they can be conjugated. This sometimes needs Ecoli strain changeover if host has a methylated DNA restriction system. Plasmids without conjugative element can be moved into Streptomyces via protoplasting

Predatory conference check Q:
Is the Global Food & Agri Summit 2026 in the Netherlands a predatory conference or is it legit?
#science #conference #predatory?

Dr Geertje van Keulen @drgvank.bsky.social · 27d

Could be integrating plasmids? Streptomyces uses this a lot

A new bench at JIC in memory of Helen Kieser. She moved to Norwich with David Hopwood in the 1960s and was instrumental in establishing the Streptomyces group and Molecular Microbiology @johninnescentre.bsky.social. Hard to overstate her importance to the #streptomyces field and community.

“Writing an essay is hard because it forces you to use your brain in ways you haven't before…Your job is not to turn in completed assignments; it's to learn how to think. Turning in completed assignments can help you learn how to think, but only if you're the one who completed them.”
