🚨 New preprint alert 🚨 We've generated a new gapless genome of Caenorhabditis brenneri🪱, one of the most diverse metazoans! We compared its genome and gene organizations with other nematodes with smaller population sizes. Check it out! https://t.co/y4LwypFRkT

I spent months illustrating how Transformers actually work. Not just what they do, but why they’re built this way. The history, design choices, and intuition behind every layer. From RNNs → Attention → Multi-Head → FFNs → Positional Encoding. Here's everything I wish I

🚨 Excited to share this #preprint from my postdoc in the Lippman lab @CSHL, in collab. with @mike_schatz & many others! Using pan-genomics & pan-genetics across the Solanum genus 🍅🥔🍆 we reveal gene duplications 🧬 as contingencies in crop engineering.

Widely observed negative correlation between recombination rate and TE abundance is usually interpreted as recombination rate being the "cause," influencing the efficacy of selection purging TEs. Yet, our recent study "flipped" this causality! https://t.co/skk0F52uAP… (1/5)

Have you ever wondered whether modularity is the only driver of transcriptional network organization? Short answer, no! There are nuances to transcriptional networks, and together with @diogro and Julien Ayroles we explored some methods to find them:

DNA and RNA is not enough. Epigenetic state is necessary for drug development + basic biology. Understanding ATAC-seq data requires interactive + genome scale operations. We present a suite of interactive + publication-quality tools, in Python, to view chromatin accessibility.

How many genes for the starch-digesting enzyme amylase to you have? More than your non-agricultural ancestors. It may affect how many cavities you get. https://t.co/yrdGo1Xt44
