Third (& last?) intense week of #RNA server-only targets on #CASP17: small molecule binding ribozymes and aptamers & more group II introns in multiple states. Strange mix of natural and non-natural RNA and compounds and proteins. Looking forward to less crazy pace in next weeks.

The 2nd week of #CASP17 is closing, with more group II introns and some other RNAmake synthetic designs — the dimer targets for both kinds of targets seem challenging! And more #RNA targets are coming in week 3: predictioncenter.org/news.cgi#557

Latest #CASP17 #RNA targets are a tiny aptamer for tryptophan selected by Yarus lab @colorado.edu, a miniTTR by RNAmake @josephyesselman.bsky.social, and 2 singlet glycine riboswitches discovered by Breaker & Strobel labs. Note first one: 25-nt RNA by #cryoEM? predictioncenter.org/casp17/targe...

First natural #RNA in #CASP17 is a group II self-splicing intron, and it’s also the season's 1st multistate target! Will server algorithms detect homologous group II intron structures to help modeling? Can servers model both unspliced and spliced states? predictioncenter.org/casp17/targe...

More #CASP17 #RNA targets: OpenKnot @eternagame molecules from AI designers @rosettacommons.bsky.social @chaitjo.bsky.social & triphosphorylating ribozyme selected by Muller lab. All 8 RNA targets are non-natural — how will modeling methods do without MSAs, templates, homologous training examples?

First two targets in #CASP17 are #RNA, and they're designs from the online videogame @eternagame.org. Hope the bots preparing for CASP have been playing Eterna!

The 17th Critical Assessment of Structure Prediction #CASP17 begins tomorrow. 2 #RNA targets per day for next few weeks! >60 servers registered already, including @kaggle teams. Join the fun at predictioncenter.org/casp17/

Results are in for @stanfordmedicine.bsky.social Kaggle #RNA 3D Folding, Part 2! Top teams team_cp and AyPy together just outperform the best template oracle, another milestone in computational biology. Come join the conversation as we prepare for #CASP17: www.kaggle.com/c/stanford-r...

First public presentation of (Part 1 of) the #Kaggle 3D #RNA Folding challenge results -- see you Thursday!

In 2 weeks, 9 Kaggle teams have beat AlphaFold 3 score (0.372) in predicting hidden 3D structures of #RNA, including complexes with small molecules & proteins. What will it take to beat the best template oracle (0.554)? www.kaggle.com/c/stanford-r...

Large and intricate naturally occurring structures composed exclusively of RNA... ROOL! More at Molecule of the Month: pdb101.rcsb.org/motm...

Inspired by 2025 Stanford #RNA 3D folding @kaggle challenge outcome, we’ve collected cryo-EM of new-to-Nature RNA folds, RNA complexes with small molecules and proteins, and assemblies up to 6000 nts - and launched PART 2! Deadline: March 2026. www.kaggle.com/c/stanford-r...

Preprint on the Stanford #RNA 3D folding Kaggle challenge is out. My scientific new year’s resolution is to brush up on template-based modeling. #gofai www.biorxiv.org/content/10.6...

A new 3-state Replicase challenge has been launched on Eterna and will only be open for two weeks before sequences are collected for experimental testing at the Das Lab. Will Eterna players be able to improve the catalytic activity of the RNA polymerase? eternagame.org/labs/14183416

Wonderful collab with Fu and Zuchero labs, led by @vedtopkar.bsky.social in our lab. How do molecules make it out to the myelin sheath? For the most expressed protein in oligodendrocytes, an #RNA switch appears to be the answer. Meng-meng's posts explain it best!

@eternagame got single RNAs to compute functions like all logic gates, A>B, and A*B/C^2, relevant for tuberculosis detection! Now looking for partners to scale to complex applications. Collab w/ Greenleaf Khatri labs @christianchoe.bsky.social @stanfordmedicine.bsky.social at doi.org/10.1038/s415...

#MD blind predictions of water/ions around Tetrahymena ribozyme #RNA matched cryo-EM data better than our baselines! Congrats #CASP16 + @rachael-kretsch.bsky.social + 23 brave groups. Still a ways to go — time for #DeepLearning of water? Community paper: doi.org/10.1002/prot...

Our work presented today at the www.youtube.com/@CASPRNASIG online seminar! @bussigio.bsky.social will report on the #CASP16 solvation challenge and 2D ensemble reconstructions using #DMS data

Assessment of blind 3D structure modeling of #RNA and nucleic acid complexes now out in the #CASP16 special issue, led by @RachaelKretsch. We hope this benchmark, paper, metrics, and expert baselines drive much-needed progress by #CASP17 (May 2026)! doi.org/10.1002/prot...

The results are in: top codes in Stanford #RNA 3D Folding @kaggle.com competition are competitive with CASP16-leading humans Vfold, beat AlphaFold 3. Top team’s trick was template-based modeling, not #DeepLearning. Congrats: john, odat, Eigen, + all 1706 participants! www.kaggle.com/competitions...

Meet @frameshifter.org, the new nonprofit program established to steward Eterna's future and advance public engagement in scientific research through games, collective and hybrid intelligence, and human centered design.

Community science presents an alternative discovery framework for precision ASO drugs. A community voting system facilitates the testing of top designs, followed by experimentation to evaluate and score how well player-designed drugs ameliorated molecular disease phenotypes bit.ly/44u5oTv

Highly collaborative efforts that involved 6 lab members and the labs of @yiliangding.bsky.social and @rdaslab.bsky.social. We uncovered a telomerase dimer and its potential role in telomere maintenance.
