🚀 New tool out! LIVIA (Local Interaction Visualization and Analysis) — a browser-based tool for assessing and visualizing predicted protein-protein interactions.

Drop in a prediction from AlphaFold-Multimer, AF3, ColabFold, Boltz-1/2, Chai-1, or OpenFold3 (ZIP or folder, auto-detected) and LIVIA answers the two questions you actually care about:

▸ Do these proteins interact?
▸ Which residues form the interface?

What you get:
▸ Interface confidence scores — iLIS (our local metric), ipSAE, actifpTM, ipTM
▸ Interaction interface heatmaps (PAE, LIS, cLIS)
▸ Sequence viewer + linear & circular contact maps highlighting Local Interaction Residues (LIR) and contact LIR (cLIR)
▸ Embedded Mol* 3D viewer
▸ Downloadable ChimeraX & PyMOL scripts

Also fetches dimers directly from the AlphaFold Database — adding the interface annotations AFDB doesn't provide.

Everything runs locally in your browser. No install, no upload.

LIVIA started as a personal tool — I built it with Claude Code and used it to make every structure figure in our FlyPredictome preprint (Kim et al., 2026). (Claude Code is truly insane...) Along the way I realized it could be useful for others, too.

If you have a favorite color palette for structure visualization, please let me know — happy to add it as a preset 🎨

Much delayed but never never. Full of genetics and TRANSgenetics. And fly brains are smarter than orange. Enjoy!! @CSHLPress @CSHLflycourse @GeneticsGSA

Wow this is scary. I always use “extra virgins” like the one in your picture. Now what do we do? You can avoid males :)

This years Drosophila service award goes to the yeoman efforts over many decades by the leadership and staff of the Bloomington Drosophila Stock Center; no fly lab exists that does not owe them a huge debt of gratitude 🙏 congrats all!

Interested in doing Ca2+ imaging at the fly NMJ? Excited to have this protocol out detailing GCaMP8 imaging at pre- and post-synaptic compartments, check it out!

Mind-blowing 🤯🤯🤯
@SfNtweets Executive director of SfN: Salary $751,996/yr, working 35 hours per week!

I guess now you know where your Abstract submission fees & Membership fees have been going?

Hey, Postdocs, What is your salary and how many hours do you work?

[Daryl Gohl @DarylGohl]

Really excited to share this new preprint on automated microinjection of Drosophila and zebrafish embryos! See this thread by our collaborator @bksuhasa
