In 2014, Jason Rosch and I met at a GRC in Tuscany and sketched an idea on a cocktail napkin: what if we evolved S.pneumo in mice, treated them with antibiotics, varied their immune systems and watched what won? 11 years and a huge team effort later, it's out in @cp-cellhostmicrobe.bsky.social 🧵

Phenotypic Heterogeneity in Lag Reflects an Evolutionarily Stable Bet-Hedging Strategy
Driven by metabolic growth-lag trade-offs, the diversification of clonal yeast into two distinct phenotypes acts as an evolutionary rheostat that maximizes long-term fitness.

What a great article not only on faculty workloads, but how little our salaries actually factor in to most university budgets. A few highlights. First, our salaries are falling:
I had a really fun time joining @blarson.bsky.social on @scifri.bsky.social to talk about the strange and fascinating world of microbial weapons: swords, bombs, cannibalism, poison, and what this means for how microbes compete, feed, and shape communities. www.sciencefriday.com/segments/kil...
Swords, cannibalism, poison: inside the world of killer microbes
Some microbe species have evolved to stab, bomb, cannibalize, or poison each other. Can we harness their weapons for good?

Researchers like Ben Larson and Glen D’Souza are piecing together the world of killer microbes, including why they turn on each other and if their tiny weapons could be harnessed to fight disease. Listen to the podcast now: www.sciencefriday.com/segments/kil...

one anecdote: I was searching for a link to one of my old papers on Google, and the automated Gemini summary attributed all of my lab's work to my husband
When utilized in literature review, LLMs consistently 1. fail to mention female authors in female-led literatures, 2. insist that men are more influential or more heavily cited when this is contradicted by objective citation counts, and 3. attribute women’s work to hallucinated male scholars.

1/7 We often picture eukaryogenesis as a symbiosis between two lineages: an archaeal host & the ancestor of mitochondria. But what if the origin of eukaryotes emerged within a much more complex microbial ecosystem? A fascinating study from @tonigabaldon.bsky.social et al. explores exactly this. 🧵
Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...
