Published in Infection and Immunity, Gracious Donkor and I explore the diverse mechanisms microbes employ to withstand ROS-mediated stress and discuss recent efforts to harness oxidative stress responses as a potential strategy for developing new antimicrobials. journals.asm.org/doi/10.1128/...

Day 1 of @asm.org #ASMmicrobe2026 was great! Wonderful reconnecting with the Microbiology community, including fellow @hypothesisfund.bsky.social family members @laahrs.bsky.social & @paulturnerlab.bsky.social!

Abstract suggesting that some protists can use symbiosis for magnetoreception. Promising direction, seeing as there have been zero magnetoreceptors discovered outside bacteria... www.nature.com/articles/s41...

Why we must keep funding research: “The long scientific journey that led to the drug is a triumph of both public and private research funding, succeeding only after decades of false starts and dashed hopes — and the unraveling of conventional wisdom that turned out to be completely wrong.”

By all means, if you're deciding, take the time you need. But if you're deciding between two places, and there are three others you've ruled out, let those three know as soon as possible, not once you've picked a school You could make a huge difference to someone else's life

Annual reminder: if you’ve been accepted to multiple graduate programs and are still deciding, please let the ones you’re definitely not going to know as soon as possible! -Someone who got into his PhD off the waitlist the day after the deadline

(bacterial) cell divisionists take note 👇 the schwille lab did it again! now adding FtsN*) to the party, with FtsA, FtsZ and the Min gang already on board... *) cytoplasm.domain thx séamus for pointing this out🙏 #MicroSky

Happy #InternationalWomensDay to the brilliant women in our Hypothesis Fund community who are taking the intellectual risks to pursue bold ideas, supporting one another, and transforming science together. You inspire us every day. 💫 #IWD2026

#OnThisDay in 1938, American evolutionary biologist Lynn Margulis was born. Margulis is most known for developing and popularising the endosymbiotic theory, which explains how eukaryotic cells evolved organelles from simpler prokaryotic organisms that resided within another and became incorporated.

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22

Preprint on the permeability of Gram+ bacterial cell wall from a few months ago. Intriguing findings, elegant methodology. Cell wall is largely impermeable to molecule sizes of mNeonGreen (27kDa) and above. How do larger secreted proteins get through? www.biorxiv.org/content/10.1... #microsky

a daring approach: looking at LUCA's ancestors, i.e. pre-darwinian evolution. but not surprising it's coming from @kacarlab.bsky.social 👏 glad to see Iwabe et al. (1989) among the references (blew my mind when it came out >30 y ago)

Can’t wait!! My bacterial cell bio friends, you’re gonna want to go to this GRC and GRS.

Absolutely stoked to have this published in @plosbiology.org We looked at the metabolism of #Klebsiella pneumoniae 🦠🧫. We not only demonstrated lineage-specific #metabolism, but that lineages can cross-feed and support each other. journals.plos.org/plosbiology/... #MicroSky #microbiology 🧬 🧪 💊

The diderm cell envelope is not a stack of layers but a unified scaffold of Inner Membrane–Peptidoglycan–Outer Membrane.

Weird word of the day: "kleptosquamy." The testate amoeba Awerintzewia cyclostoma steals scales from other amoeboid organisms to build its own shell. This one has robbed Quadrulella, Netzelia, various euglyphids, and even an Acanthocystis. Kleptosquamy! #amoebae #ProtistsOnSky #biology #nature

Prashant Singh in the lab of Tina Iverson at Vanderbilt published this image of the bacterial 🦠flagellar motor, a detailed molecular model made possibly by CryoEM 🔬. The similarity to mechanical motors are strong enough we can use terms like stator, rotor, rod & gearing to describe it.
