A thoughtful and beautifully written @quantamagazine.bsky.social article about genome regulatory innovation at the origin of animals. Featuring some of our work and highlighting key open questions. Thanks to @philipcball.bsky.social for this fantastic piece.

Agreed! But that's when it would be nice to see actual distributions instead of box plots.

the surprise in this plot is that the NRL is not quantized. Would be interesting to see a distribution of NRL for each point.

New paper!
We generated and/or (re)analyzed ~100 #metagenomics Hi-C datasets to provide a comprehensive analysis of bacterial and viral metagenomes across VERY different environments.
Congratulations to all authors especially Amaury Bignaud and @mmarbout.bsky.social for the huge work!

The simple machine that visualised atomic orbitals In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to the Schrödinger equation

In the early days of quantum chemistry, before we had computers to calculate the shapes of electron orbitals, one man invented a mechanical machine that simulated their shapes. My latest column for @chemistryworld.com

Excited to share my postdoc work, out on bioRxiv today! Histones package DNA into nucleosomes to form the building blocks of chromatin, but how modular and programmable is this system? 1/9

Today marks the end of en-JUNE-eering, the month where I focused mostly on the nitty gritty of improving genomics ML infrastructure.

Here are some of the highlights:

📢 New paper out in Mol Syst Biol!
During the development of WT yeast colonies, small cell subpopulations experience transient, high-intensity mutational bursts. Such hypermutation episodes are modulated by the DNA damage tolerance pathway 🧬

Diagram of chromatin and nucleosomes from https://www.genome.gov/genetics-glossary/Nucleosome

The DNA in our cells is not naked but instead is compacted by being wrapped around nucleosomes assembled from histone proteins. In our current view, this produces the chromatin architecture that leaves some regions open for transcription while others are more compacted & transcriptionally silent 1/n
