🌱✂️ How do plant cells decide where to divide?
Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.

Incredible Molly Herring wrote a story on the philosophy behind the work we do at PrakashLab. Wonder & curiosity.. even more important to share when every day is a new attack on the fundamental principles of scientific explorations. Thanks @quantamagazine.bsky.social for this interaction.
Manu Prakash practices “recreational biology,” a scientific approach that explores life in the same playful way that puzzles probe math. “Basic science is not at the service of something, but the groundwork that is our entire society’s foundation.” www.quantamagazine.org/how-paradoxi...
How Paradoxical Questions and Simple Wonder Lead to Great Science | Quanta Magazine
Manu Prakash works on the world’s most urgent problems and seemingly frivolous questions at the same time. They add up to a philosophy he calls “recreational biology.”

Can Germany rein in its academic bullying problem?

Stomata form alignments in many species, we do not know how. So, we forced a lot of cells to differentiate into stomata, and we watched them dividing, with modelling, and mechanical perturbations, we conclude that they were aligned by mechanical stress derived from differential growth
