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...

"Curiosity-driven research is really the seed corn for the major breakthroughs and applications. But it’s also important in its own right, because discovery and the expansion of knowledge are virtues in themselves." Thanks @neilshubin.bsky.social (gift article) www.nytimes.com/2026/06/12/s...

After a long hiatus, happy #MicroscopyMonday! Here are some amoebae squeezing themselves into narrow channels (part of a video for our preprint pubmed.ncbi.nlm.nih.gov/41377514/). Sound effects by Dillon (my 4 month old who may have had a little to do with the bluesky hiatus!)

Yes definitely! As a starting point, our lab had compiled a database of dynamics measurements for various TFs obtained through SMT, FRAP, FCS etc. (www.mir-lab.com/dynamics-dat...) and we want to continue to expand it.

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)

"Elsevier incurred costs of around £1.7 billion last year, which included investment to develop new technology and for improving services." Let that sink for a min. $1.7B expenses ($2.7B revenue and $1B profit) and they expect us to believe they're developing any sorts of technology.

Elsevier costs were ~£1.7B in 2025 newsletter.journalology.com/p/elsevier-2... Compare that to arXiv 👇

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...

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!!

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!

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!

Collective cell motion has many forms, but rotation is the coolest of them all. I'm @onenimesa.bsky.social , and in this short🧵, I'll highlight some instances of global tissue rotation like this one from @BauschLab

Trump doesn't seem to see that some people are still immune to his threats. Jack White criticized Trump's Oval Office decor. The White House then called White a "washed-up, has-been loser... masquerading as a real artist." And White, undeterred, posted an absolutely blistering takedown in response.
