Psilocybin reshapes how the brain is connected. 🧠⚡️

Using viral tracing methods, the study found the psychedelic strengthens pathways related to sensory processing and weakened those tied to rumination.

It's with heavy hearts that we share that Claude, our beloved albino alligator, has passed away at the age of 30. Claude brought joy to millions of people at the Academy and across the world during his 17 year tenure. We will miss him dearly. 🤍

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen.

Synergy between cis-regulatory elements can render cohesin dispensable for distal enhancer function

now revised and journal accepted at www.science.org/doi/10.1126/...

Bah, who needs cohesin if you're at the right place (near). Grover once taught us the difference between near and far (my favourite Sesame Street piece), and now amazing work from @elphegenoralab.bsky.social led by @karissalhansen.bsky.social shows us how: www.science.org/doi/10.1126/...
Synergy between regulatory elements can render cohesin dispensable for distal enhancer function
Enhancers are critical genetic elements controlling transcription from promoters, yet how they convey regulatory information across large genomic distances remains unclear. Here, we engineer pluripote...

Frog and Toad ate many cookies, one after another.

“You know, Toad,” said Frog, with his mouth full, “I think we should stop eating. We will soon be sick.”

“You are right,” said Toad. “Let us eat one last cookie, and then we will stop.”

1/ Public datasets feel like a goldmine.
But look closer—there are landmines hidden inside.
Especially for single-cell RNA-seq.

1/ One of the biggest hidden killer in bioinformatics?
Not a bug. Not a crash.
It’s the 0-based vs 1-based coordinate trap.

We are excited to share our online book and preprint on “Orchestrating Spatial Transcriptomics Analysis with Bioconductor”!
Many people hours, calls and messages later: OSTA is now “in (pre)print”, though the real thing lives at bioconductor.org/books/OSTA.

Check it out, get in touch. We welcome any feedback, suggestions, wishes (& contributions).

It’s been a joy working with you @estellayixingdong.bsky.social!

A new study shows that neurons repair CRISPR-Cas9 cuts in unique, highly predictable ways, unlike dividing cells. Researchers found Cas9 persists far longer in neurons and triggers unexpected repair p...

I was loving Claude Code... until I tried it with #rstats. Constant errors, wouldn't use the tidyverse even when asked, "optimized" functions were slower.

Frustrated, I started a session just to teach R to Claude and summarize what it learned into a CLAUDE.md file gist.github.com/sj-io/3828d6...
