Redirecting

The diderm cell envelope is not a stack of layers but a unified scaffold of Inner Membrane–Peptidoglycan–Outer Membrane.
We discuss how tethering the OM to the PG in E. coli preserves integrity β€” and extend the concept across diderm bacteria.

The Penicillin Myth Competing theories seek to explain inconsistencies surrounding Alexander Fleming’s famed discovery.

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.
