The first preprint from my PhD is out! :thread: How does an animal choose between two completely different reproductive fates? Here’s how one planarian does it :point_down: www.biorxiv.org/content/10.6...

Life-cycle trajectory inference links temperature-gated progenitors to reproductive fate
Temperature shapes reproductive strategies across animals, yet how individuals switch between sexual and asexual reproduction remains unknown. We establish the planarian Phagocata morgani as a model f...

While getting beers with @genikhovich.bsky.social a moment is guaranteed: he pulls out a pen and starts drawing embryos on a napkin: “Here goes the mouth, wnts go there, beta-catenin …” Yesterday I was doing the same to my flatmates, colleagues and friends. What an insane and elegant science! 🖤🪼

For the last 3 years, my personal world has been in flames - the loss of home, the loved ones, friends and the other things we often take for granted. Roscoff feels like a personal refugium - a timeless place where one’s soul can hide & think about things that really matter.

These negative synergies create a sensor of TF ratios. If one TF’s expression dominates, you get activation. If both are there, repression. A perfect design to ensure that target genes are expressed specifically at the right place. (9/n)
