I just completed my first radio 📻 interview ^_^

You'll be able to listen to it next Friday or so at www.iheart.com/podcast/269-.... Thanks Clau from iHeartRadio Miami's "Estamos Contigo" podcast for reaching out!

I'll be talking in Spanish about our recent #HabenulaLIBD 📜

Hot take: ggplot2 is better than any plotting option available in Python-- but I discuss a couple options in Python at an R Stats Club session @libdrstats.bsky.social linked below. I personally use plotnine, since it's essentially a port of ggplot2 for Python.

Congratulations to our habenula team! We've learned a lot about working in this tiny brain region. Here we characterize the molecular signatures of human habenula cell types and transcriptomic changes associated with schizophrenia. Stay tuned 👀 for more exciting habenula findings in the near future.

I loved the "Hmmmmmm" in the crowd when @jcheng5.bsky.social showed this data quality problem uncovered by the #positron Databot tool.

No human caught this during the Tidy Tuesday for the data.

I've been skeptical of AI for data analysis, but this is an extremely compelling use case. 🫣
