Great to see our patient map of heart failure across patient cohorts, scales, and techs out.

Hope that our work shows how we can transform molecular data into interpretable tissue features that describe remodeling and associate with clinical outcomes.

Cardiac tissue remodeling in heart failure is driven by interactions between multiple cell types, but existing studies have not fully captured these coordinated responses. Here, the authors show that ...

Our Systema framework for evaluating genetic perturbation response prediction methods is now out in @natbiotech.nature.com

Systema helps to evaluate perturbation response prediction methods by focusing on perturbation-specific effects rather than systematic variation 🎯

Ever wondered how to best quantify cell-cell neighbor preferences in tissues?
We compared 9+ neighbor preference (NEP) methods for analysing spatial omics data and propose a novel approach that combines the most relevant analysis features which we call COZI 🔬✨

📄 Update on our preprint about Gene Regulatory Net (GRN) benchmarking 📄
We have included the original and decoupled version of SCENIC+, added a new metric and two more databases. Dictys and SCENIC+ outperformed others, but still performed poorly in causal mechanistic tasks.

Academics from poorer socio-economic backgrounds are more likely to
- not publish
- have outstanding publication records
- introduce more novel scientific concepts
- less likely to receive recognition, as measured by citations, Nobel Prize nominations, and awards.
