📷⚙️ TECHNICAL INNOVATION ⚙️📷 Ohad & Meroz developed a modular camera-based system to measure weak forces generated by freely moving plant organs. It measures the force projected on two axes, is cost-effective, modular & accommodates a wide range of organism scales. 🔗 doi.org/10.1093/jxb/...

Active matter physics studies living beings as open, out of equilibrium, and emergent systems. In this perspective on plant morphogenesis, we show how such features arise from the basic hydromechanics of plant tissue and how to capture them in models. 🌱💧 Preprint 👇 arxiv.org/abs/2512.05554

New preprint! Do you like ocean waves? We found similar waves on bacterial colonies! We found that this collective behavior, known as rippling, is nothing but surface waves on an active nematic. @princeton.edu @mpipks.bsky.social @ub.edu @icreacommunity.bsky.social www.biorxiv.org/content/10.1...

New preprint! SOSEKI polarity proteins are mechanoresponsive integrators linking growth and tissue mechanics during lateral root formation. Their polarity marks growth boundaries and reorganises in response to mechanical alterations —reshaping how we think about axis formation. tinyurl.com/28p7af2w

Beautiful!

How fast do plants actually grow? And which growth processes matter most for organ size? We dived into 176 papers, extracted and re-analyzed the data so you don’t have to! nph.onlinelibrary.wiley.com/doi/10.1111/... @newphyt.bsky.social @virajalim.bsky.social @elvisbranchini.bsky.social

One day in the lab, we accidentally discovered that the spines of a cactus 🌵 straighten when exposed to fog. I was intrigued and so were my collaborators. How does this work and what can be gained from it? Here are some of the answers in our new preprint: doi.org/10.1101/2025...
