Cilia alert! Last year Juyeon Hong described a new domain in 9+2 cilia called the EDT, the extreme distal tip. Now, she's found a new protein required for its assembly, but only in non-mammalian vertebrates. A cool evo-cell / protein evolution story in @cellreports.bsky.social tinyurl.com/2xvdskx6

Can we predict which T cells recognize which peptides? A lot of the signal is hiding in AlphaFold3's (AF3's) hallucinations. enFoldX: instead of one predicted structure, we use the whole noisy ensemble to predict TCR:pMHC binding. www.biorxiv.org/content/10.6... 💻 🧬 github.com/jonlevi/enFoldX

Thrilled to share our collab led by Grace Hibshman with the Shipman lab! Type IX retron-Kva2 structure reveals phage detection via an HTH fold, not a primary sequence. We computationally designed triggers that program bacteria cell death, pointing toward designer antimicrobials.
Let's learn a lesson from the nearly 500K of us who mobilized to comment on the OMB rules. We can leave the sidelines, take action and it can make a difference. After 15 months of inaction, our scientific societies finally woke up and mobilized members. It doesn't stop there 1/n
Zero-shot predictions of mutational effects seem to work well in benchmarks but frequently fail in targeted protein engineering campaigns. Why is that? blog.genesmindsmachines.com/p/how-useful...
How useful are zero-shot predictions of mutational effects?
Zero-shot predictions are great, except for when it matters

There are many comments up on the OMB rule but there are now many that claim to be in favor of the rule and they are well written and anonymous- claiming to be tenured professors worried about waste fraud and abuse. We need as many real, unique comments as possible that show how bad this rule is
There's an OMB rule change that would require political oversight of scientific grants, and could pull any that don't "reflect presidential priorities" Another country has tried this before! It was the USSR and it was called Lysenkoism. By @thsaey.bsky.social www.sciencenews.org/article/omb-...
🚨 HEADS UP: If you haven't submitted a comment on the OMB proposal yet, there's still time - but it's running out! There are only 3 days left to push back against Russell Vought's attempt to give political appointees unprecedented control over federal research funding. Take Action: zurl.co/J92d9

Critical reasons to comment on the OMB rule, especially asking to extend the comment time for such a complex ruling with far reaching implications
www.regulations.gov/commenton/OM... Submit your comment here. Read this short piece by lawyer Claudia Polsky to see why science needs you and all your friends and colleagues to write. It’s fast and easy and it will make a difference.

You may have heard about the OMB rule change that will put politics over federal grants. However bad you think it is? It's probably worse. Thanks to @theverge.com for letting me report this one out. There is still time to comment. bit.ly/4v2X4nQ
I've gone ahead and posted my comment on the OMB rule as an example of a hyper-focused comment that looks at one portion of the OMB rule. Here, I've tackled a part of the Rule I know a lot about (international research and national security) and cross-walked with a project I've worked on a lot.

Cole Donovan, Director of Policy at the SUFS Foundation, breaks down how OMB’s grant rule will undermine U.S. research, weaken international collaboration, and threaten American scientific leadership.

Thanks, @olibclarke.bsky.social! Identifying this complex is good news for our job security as experimentalists... As of today, we still can’t predict the full assembly with AlphaFold. So here is an #open_challenge: if anyone can recover the whole complex computationally, I’d love to hear from them!
Amazing stuff, what a structure! Elegant work😍
🔬 Your tax dollars once paid a physicist whose own colleagues told him he was wasting the university's money. In 1951, Charles Townes sat on a D.C. park bench and worked out, on the back of an envelope, how to force molecules to release coherent radiation. 🧵 1/5
This is a tremendous piece by Judy Stone at @forbes.com. This new OMB rule is going to hurt communities from coast to coast. Federal grants are not just about research! www.forbes.com/sites/judyst...
How The OMB Rule Could Hurt You And Your Town
The OMB proposal threatens scientific research and ALL federal funding for states, cities, and nonprofits. It politicizes ALL funding. Call your reps and write an objection.

We’re delighted to welcome @computingcaitie.bsky.social to the FMI next year! Her work will bring an interdisciplinary perspective spanning structural biology, quantitative imaging and computational analysis to our institute, opening exciting new ways to study ciliary structure and dynamics.
Happy to finally share that I will be starting my independent group at the @fmiscience.bsky.social in Feb 2027 in a vibrant new environment. We will use integrative in situ structural cell biology methods to investigate ciliary structure and dynamics in several model (and non-model 👀) systems!!

If you like cilia, go work with my friend Caitie! 👸🏼🥳🔬 Also, guaranteed unlimited lab snacks 🍬🍫🥨🥯

#Bugsky 🐙🌿 Shared with me by a fof in SoCal - this is a gynandromorph (both male & female) valley carpenter bee (Xylocopa sonorina). Females are black, males orange, so the extreme color dimorphism really stands out. Per Doug Yanega at UC Riverside, bee gynandromorphs he’s seen are mosaic instead—
It’s truly astonishing to see how comprehensively the US government is tearing down every part of the system that has made it up until now a world-leading power in science, research, and technological development. The entire world will suffer from this wanton destruction.
