Earliest sunsets are almost here. In early to mid-December, evenings become brighter again—no “Daylight Saving Time” needed!

In the era of chatGPT, Claude, Grok, DeepSeek, Perplexity etc and finding an email in outlook using keywords is literally impossible….

Great visit to UW Madison, microbiology home base! Thanks to Jason Peters for hosting! See you at Phages! 👋

Very proud of our recently published work in @narjournal.bsky.social led by senior PhD candidate Julia Warrick. #RNA academic.oup.com/nar/article/...

It’s normal for colleagues in a field to share and discuss their unpublished results. What’s not normal is basing your entire model off of those results and declaring yourself the winner. Announcing that that is what you did IN YOUR PAPER is even weirder.

Women, we need to work harder to get noticed for ruining science.

🚨Just in press @asbmb.bsky.social JBC!🚨 Alex & Chioma's paper detailing the interaction of Fe(II) with an intact membrane His kinase for the first time! Binding stoichiometry ✅ Fe(II) structure ✅ Direct observation of selectivity ✅ Signal transmission pathway ✅ Read more here: tinyurl.com/49wdkecu

To be fair, this bot does accurately reflect the accepted modern practice of never saying anything interesting in a scientific paper.

Super proud of Dr Brayan Vilanova Cuevas for successfully defending his dissertation on Philaster diadema interactions. Well done, and watch out world!!

This month, my lab celebrated our 5 year anniversary! On October 16, 2020, I rode the L train to start my lab at UIC, as the only lab member during COVID. In 2025, we celebrated together! It’s been such an honor that all these incredible people and more have chosen to do science with me!

Excited to share my latest postdoctoral work in the Shen Lab at Tufts! In this study, we follow up on an exciting finding by former grad student @shailab.bsky.social that C diff uses its Class A PBP (PBP1) to drive cell division (unlike previously studied bacteria)! journals.plos.org/plosgenetics...

Of course Amazon runs Canvas.

I left this geranium for dead last spring in a window sill and suddenly this morning I notice one green leaf and one tiny pink flower. That’s hope y’all.

The Peters lab is looking for a new team member! The role transposons play in evolution, basic mechanisms regulating transposition, and applying transposons as tools for genome modification with a special focus on guide RNA-directed transposition. cornell.wd1.myworkdayjobs.com/CornellCaree...

I am very happy to share that I have started this week as an Assistant Professor of Microbiology at the Richard A. Gillespie College of Veterinary Medicine in Harrogate, Tennessee. It has been a beautiful journey from IAAS to Ohio State to Cornell, and now to LMU-CVM.

Apply for a #PhD with @paulhoskisson.bsky.social and me on all things #Streptomyces, #evolution, #AMR, #antibiotics, #biotech! Deadline 21st November. #MicroSky please share!

quick while the government is shut down let’s all switch to metric

Just throwing this out there as a significant conceptual advance in the field www.biorxiv.org/content/10.1...

Our lab website is live, check it out: pokorzynski-lab.squarespace.com

I can’t explain why but the last five years are one year, and then January through August is one year, and then September through December is one year but like a different year

Check out our new paper: a review of translational coupling, the phenomenon where translation of one prokaryotic gene can promote translation of the gene downstream. We cover the history, and delve into the mechanism, which is still not fully understood. journals.asm.org/doi/10.1128/...

Here is a link to a new pre-print that is a collaborative effort between our lab and the lab of Michelle Wang here at Cornell. We use single-molecule techniques to investigate how the combination of Rad51 and Rad54 remodels donor DNA during the homology search www.biorxiv.org/cgi/content/...

Here we show that >90% of Paenibacillus encode a unique Spo0B with a transmembrane domain! TM domain helps it interact with its phosphorelay partners. Congrats to @isabellalin.bsky.social who left for grad school this week and her mentor @cassidyprints.bsky.social! www.biorxiv.org/content/10.1...

Awesome work from my mentee @isabellalin.bsky.social on sporulation in non-model Bacilli!!

#MicroSky probably no less intriguing than the programmed frameshift in dnaX, which is also conserved across various phyla

We are hiring at all levels, so please help spread the word! #RNAsky #ribosomes #signaling #translation sinha.biochem.utah.edu/join

I am delighted to share that I have started my lab in the Dept. of Biochemistry @uofubiochem.bsky.social at the University of Utah @utah.edu. My laboratory will study key aspects of protein synthesis and translational control in healthy and diseased states. #RNAsky sinha.biochem.utah.edu

Sea star wasting disease represents a suite of stress responses. Recent work by Prentice et al (2025) identified Vibrio pectenicida FHCF-3 as causing a SSW condition in Pycnopodia helianthoides. I investigated this bacterium’s autecology. www.biorxiv.org/content/10.1...

Check out our new preprint on the discovery of a molecular switch in NAC that mediates nascent chain sorting on the ribosome and prevents mitochondrial protein mistargeting by SRP. A great collaboration with the Shan Lab @Caltech and the Qi Lab @UVA: www.biorxiv.org/content/10.1...

Latest from the lab! Analysis of everyone’s favorite regulatory mechanism in bacteria — the RF2 programmed frameshift! Likely present in the ancestor of bacteria, use of this mechanism is influenced by stop codon usage! Big congrats to @cassidyprints.bsky.social journals.asm.org/doi/10.1128/...

Just published the first chapter of my thesis! 🥰 E. coli regulates the levels of a translation release factor (RF2) via a *purposeful* frameshift during translation. We found that most other bacteria do this too and it's likely an ancient mechanism! journals.asm.org/doi/10.1128/...
