Our paper benchmarking feature selection for scRNA-seq integration and reference usage is out now www.nature.com/articles/s41...! Keep reading for more about how we did the study and what we found out 🧵 👇 1/16

🚨🧠 New paper alert: Stress alters neuronal balance in the developing brain 🧠🚨 Our latest study in @science.orgAdvances explores how glucocorticoid exposure—a key environmental risk factor—shapes early human brain development using #organoids. @mpi-psychiatry.bsky.social @drcricru.bsky.social 🧵👇

Chronic exposure to glucocorticoids amplifies inhibitory neuron cell fate during human neurodevelopment in organoids

Chronic exposure to glucocorticoids during brain development leads to priming of the inhibitory neuron lineages in organoids.

When applying machine learning to human health data, it is not enough to just improve a metric by another percent. We have to go deeper. In our perspective in Nature Cell Biology, we discuss caveats and biases of human single-cell data analysis: nature.com/articles/s41... 🧵 1/10

Biases in machine-learning models of human single-cell data - Nature Cell Biology

This Perspective discusses the various biases that can emerge along the pipeline of machine learning-based single-cell analysis and presents methods to train models on human single-cell data in order ...
