Working with you all was AWESOME! Yes, a part of it was because we brought cell and evolutionary biology together in a fun way. But I think it was also because you guys are such kind, motivating and exciting collaborators!!! We must do it again!

Such fun collab with the @vjesticalab.bsky.social @unil.bsky.social, revisiting the first question I became obsessed with as a PhD student: why do cells that fuse during sex need to differ genetically even when they look the same? 🙌 Celso Martin and Harry Booth for beautiful experiments+theory work

Pour les francophones intéressés par la science, veuillez consulter ce communiqué de presse de @unil.bsky.social sur la façon dont les différences entre les gamètes partenaires (ovule♀️ et spermatozoïde♂️) commencent à apparaître dans l'évolution ! Merci @nathalieisorce.bsky.social

You may also wanna check out this popular science blog about our work! It's a fun read on how the two gametes (egg♀️ and sperm♂️) start to become different? This has been a fantastic collaboration with @zenahadjivasiliou.bsky.social and Harry Booth, spearheaded by @celsomics.bsky.social !

The kymographs (left-to-right) follow the mating of a fission yeast gamete pair. One gamete expresses a cytosolic marker (blue) that spreads as partners fuse. Nuclear marker (magenta) allows visualization of partner nuclei fusing, oscillating and undergoing meiotic divisions. Gametes express the meiotic factor (green), which is induced in one gamete first and degraded during meiosis.

Why did the two gametes (egg♀️ and sperm♂️) start to become different? It's a strategy to optimize the costs and benefits of investing into offspring! Read our brand new @pnas.org story that finds a molecular mechanism behind this evolutionary idea proposed in 1972 by Parker, Bell and Smith.

💡 Pourquoi, chez la plupart des êtres vivants, les deux partenaires sexuels ne contribuent pas de la même manière: l’un investit beaucoup (comme l’ovule), l’autre beaucoup moins (comme le spermatozoïde)? Des réponses dans cette nouvelle étude @vjesticalab.bsky.social 👉 www.unil.ch/news/1782827...
