Now properly published at @natcomms.nature.com with few additional experiments incl. demonstration of Daptomycin's ability to depolarise non-growing cells.
See the original preprint-thread for a summary of our findings.

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.

Hey folks, as news of Watson's demise spreads, please don't set aside his weighty legacy of misogyny and racism. He was truly among the worst of us. www.vox.com/2019/1/15/18...
DNA scientist James Watson has a remarkably long history of sexist, racist public comments
“People say it would be terrible if we made all girls pretty,” he said in 2003. “I think it would be great.”
