Every biologist knows the story of Fleming's chance discovery of penicillin. But is it true?

Here, with @asimovpress.bsky.social, I write about inconsistencies in the canonical story, and explore a few alternative theories about what really happened in that St. Mary's lab in the summer of 1928.
The Penicillin Myth
Competing theories seek to explain inconsistencies surrounding Alexander Fleming’s famed discovery.

I am by no means a prominent public intellectual, but my inbox is increasingly filled with messages from people who have been convinced by sycophantic chatbots that they have discovered revolutionary theories that entirely upend our scientific understanding of the universe.

Our latest paper is out with @adiop.bsky.social and @gmdouglas.bsky.social. We analyzed the extent of homologous recombination between bacterial species (introgression) and how it affects species borders (it can vary a lot depending on the approach used to classify species!). rdcu.be/eQAMf
Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy
Nature Communications - It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core...

Now online! Nutrient competition predicts gut microbiome restructuring under drug perturbations
Nutrient competition predicts gut microbiome restructuring under drug perturbations
Systematic profiling of 707 drugs on their impact on stool-derived microbial communities shows that nutrient competition explains and predicts species shifts under drug treatment and that post-drug recovery is driven by ecological interactions like extinction and strain swapping.

Excellent read. My general experience is that AI isn't going to create good, complicated code from scratch...but if you have specific things to do or translation like this, it does indeed save time.

I just wish it weren't being marketed as the be-all/end-all...coders no longer needed solution.

Sarah Kendzior was suspended this month for referencing famous Johnny Cash song lyrics in October when commenting on a WSJ article shitting on Johnny Cash. Mmmkay. Bluesky is super serious.
Wait, was she referring the fucking WSJ article that was arguing that Johnny Cash was considered uncool by music fans? The one where the fucking author just announced that he's a fucking musical illiterate?

The article referred to here:

'The Wall Street Journal' stepped in it pretty good late last week while strangely deciding to step into the realm of country music by initially characterizing Johnny Cash as "uncool."

Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

We're up to 1000 studies in metalog.embl.de ! For the past year the focus was on finding inconsistencies in the data and creating the website, but now I have more time to go through the backlog of annotated issues to do QC and load them into the database.

Can you take a quarter cup of composite sewage, simply ask ‘what’s in there?’, and find out all of the pathogens circulating in that community?

That is the question we asked in our latest pre-print.

Turns out you can.
