A call out to our former postdoc John Mallon (not in social media), who contributed to both device development and “biology” :). John evolved a salt-loving archaeon to love salt a bit less (2.6M down to 1.3M!). Cells recovered growth rate AND cell morphology. Congrats Phil, Sebastian, and John!

@breakliquid.bsky.social and I are delighted to say our OpenEVO preprint is finally live! An open source hand-made turbidostat that's modular, affordable, and made to be customized. Designed with love for the research community. Enjoy!!!💚 www.biorxiv.org/content/10.6...

1/🧵 Can transcription factor condensate formation be explained without phase separation? Our new preprint introduces SPARK, a simulation tool that reproduces condensate behavior (clustering, fusion, FRAP) from diffusion & binding kinetics alone. Movie: 60 sec FRAP sim www.biorxiv.org/content/10.6...

Thank you, we hope people use it to think about condensates in various systems! SPARK isn’t sequence-based but rather works by modulating kinetic parameters (diffusion coeff, binding probability, residence time etc.) which does affect properties like brightness and persistence of condensates (Fig 1)

The Bisson Lab at IU (bissonlab.com) is hiring makers/builders/engineers across all career stages to join our team in one of the most exciting and crazy projects I've set to work on. Candidates can email us: saltylab@iu.edu More info in the thread [1/3]

Can't miss this amazing study on the ribosome structure of the Haloferax archaeon 👏🏼👏🏼👏🏼!! Congrats to my good friend @diorgeps.bsky.social and all the other ppl involved!!

A new preprint from the @archaeon-alex.bsky.social and Joey Davis (MIT) labs! We solved the structure of the ribosome from the archaeon Haloferax volcanii and discovered a new highly conserved ribosome hibernation factor that we named AHA (AMPKγ–HPF from Archaea) 🧵⬇️ www.biorxiv.org/content/10.6...

Another paper on a topic we never worked on before: a new ribosomal hibernation! Under the leadership of the super-postdoc Diorge, Davis Lab (ribo-cryoEM master), and @vikramalva.bsky.social (protein-evo whisperer), we identified AHA (not the song, but archaeal hibernation AMPKγ factor). (1/2)

Very cool work led by @diorgeps.bsky.social from the labs of @archaeon-alex.bsky.social & Joey Davis (MIT)! They solved the Haloferax volcanii ribosome and characterize AHA, a conserved archaeal hibernation factor. With several recent related preprints, it’s an exciting moment for the field!

Excited to share this new Preprint from our lab led by PhD Candidate Carl Stone (defending Tuesday). Here we present a framework for longitudinal rbTn-Seq and apply it to the Microbial extended growth curve to resolve the fitness seascape through growth, death, and long-term stationary phase!

I am beyond excited to announce that the Bisson Lab has a new home!!! Starting January 2026, I will join the Biology Department at Indiana University Bloomington as Associate Professor with tenure. I am actively recruiting scientists across all levels. More in our website: bissonlab.com/join [1/4]

I’ve been regularly volunteering at a food bank for about a year and please, if you want to help, consider donating cash. For $3, they can provide 15 meals and what they can do with the money you might spend on a few cans can be converted to vastly more in fresh fruit, vegetables, dairy, or meat.

"Electroboy" is my memoir about my battle with bipolar disorder and which is being made into a feature film with Timothee Chalamet. The book is out of print - I have h/c and p/b copies which I inscribe to you and ship overnight to you. The cost is $30 for a h/c and $20 for a p/c - send me a DM!

This is one of my fav bac cell div papers. It's remarkable how much we've learned about cytokinesis in the past decade, and how much we still don't know. This paper harmonizes many of the disagreements in the field, like what limits construction rates (1/4)

I’m excited that the work by Diego Ramirez and Lei Yin is out, where they gained several key insights into what provides the force underlying bacterial cell division doi.org/10.1101/2025.... To divide, cells must first bend the membrane inward, a process that’s energetically expensive

It bears repeating that nearly the entire US enterprise in science and technology has been irreversibly gutted. This is shocking. All this loss has occurred without any real benefit to the average US citizen. Except we now have the biggest, best funded secret police force perhaps ever. Yay for us!
