Really grateful to see our work featured by @quantamagazine.bsky.social in this piece on the evolution of genome regulation. Huge thanks to @philipcball.bsky.social for such a beautifully written article.
I adored writing this piece. It brings together several of the things preoccupying me right now, like chromatin organization and gene regulation. There's so much more to be said on that. Also, these marine critters look gorgeous.
