Introducing Genie 3, a generative protein model that substantially advances the state-of-the-art for binder design, increasing in silico success rates by up to 20x on hard multimeric targets. It also debuts a form of inference-time scaling unobserved in other design models. 🧵1/8

New OpenFold3 preview out! (OF3p2) It closes the gap to AlphaFold3 for most modalities. Most critically, we're releasing everything, including training sets & configs, making OF3p2 the only current AF3-based model that is functionally trainable & reproducible from scratch🧵1/9

GxE interactions were documented in 264 ryegrass accessions at Nordic/Baltic distribution limits. Accounting for GxE improved prediction accuracy up to 22% for spring cover. GWAS identified large-effect variants with environment-dependent adaptive effects for persistence traits.

Have we been overstating the role of transposable elements in adaptation to local or rapidly changing environmental conditions? Happy to share my (somewhat unpopular?) opinion paper on this matter: www.sciencedirect.com/science/arti... Thanks to those who already shared the link!

Blinded by the lights? Re-examining the adaptive role of transposable elements in plants with population genomics

Transposable elements (TEs) are ubiquitous components of the genome whose mobility can be triggered by environmental stress and influenced by genotype…

Why do complex traits differ in their genetic architecture? In our new PLOS Biology paper, we will try to convince you that two simple scaling laws drive differences in the number, effect sizes and frequencies of causal variants affecting complex traits. Thread: journals.plos.org/plosbiology/...

Simple scaling laws control the genetic architectures of human complex traits

Genome-wide association studies have revealed that the genetic architectures of complex traits vary widely. This study shows that differences in architectures of highly polygenic traits arise mainly f...

Nearing 400 members on our Zeavolution slack! Want to interact with other members of the maize genetics community? We have a weekly webinar on maize diversity/evolution as well. DM me and I'll share a link to join the slack.

Travel permits of all US government employees (USDA, NSF) have been revoked shortly before the the maize meeting affecting: - The chair of the meeting - The winner of the most prestigious McClintock award - A plenary speaker - Two short talk presenters - 22 scientists presenting posters. #MGM2025

🚨New paper published in @nature.com! Using pan-genetics across the Solanum genus🍅🥔🍆we reveal why gene duplications🧬are major contingencies in crop engineering. My postdoc work in the Lippman lab @CSHL, collab. with @katiejenike.bsky.social @mikeschatz.bsky.social chatz.bsky.social and many others!

Solanum pan-genetics reveals paralogues as contingencies in crop engineering - Nature

Gene duplication and subsequent paralogue diversification are major obstacles to genotype-to-phenotype predictability.

I am happy to announce our new paper "Univariate-guided sparse regression". It's a new lasso that leverages the signs and magnitude of univariate coefficients . Sparser and more interpretable than the lasso. We're excited! arxiv.org/abs/2501.18360 R: github.com/trevorhastie...

Univariate-Guided Sparse Regression

In this paper, we introduce ``UniLasso'' -- a novel statistical method for sparse regression. This two-stage approach preserves the signs of the univariate coefficients and leverages their magnitude. ...
