This year's cohort of Pathway to Independence Fellows is visiting the @biologists.bsky.social building today for leadership and management skills training by hfp consulting. It is great for our team to get to meet them in person. Best of luck with this training!
The PI Fellows are standing in front of the Company of Biologists building in Histon, UK.

🧪⚛️ Ever wondered what would happen if you thrashed around in a water tank, creating a blob of turbulence, and then watched it spread and gradually dissipate energy? So did we. But we did the experiment, now out in PNAS and on the cover! It only took us 7 years ... www.pnas.org/doi/10.1073/...
Pictured are 3D trajectories of turbulent particles colored by speed, showing two large vortices. Takumi Matsuzawa, Minhui Zhu et al. observed the expansion and decay of a blob of turbulence created in the center of a tank of still water. The results revealed steep fronts separating turbulent and undisturbed regions, the nonlinear transport and decay of the turbulent blob, and a persistent signature of turbulence late into the decay process. According to the authors, the analysis could help provide insight into processes ranging from star formation to fusion reactors. See the article by Matsuzawa, Zhu et al. e2526858123.

Felt a little festive at the microscope this morning for #FluorescenceFriday 🎄 Here’s the nervous system of a juvenile sea star ⭐️ Green = acetylated tubulin, red = nuclei Happy holidays!
Confocal microscopy image of a juvenile sea star (Patiria miniata) viewed from the oral side. The animal has a five-armed, star-shaped body with a central nerve ring. The nervous system is labeled in green, forming radial nerve cords extending into each arm, and cell nuclei are labeled in red throughout the animal. The image appears against a black background and has a holiday-ornament-like appearance.

Our dispatch: www.sciencedirect.com/science/artic… on the recent Hydra volume EM paper by Zhang, Rafa Yuste and colleagues: #connectomics, without synapses www.sciencedirect.com/science/artic… #neuroscience
Two nerve nets are formed in Hydra vulgaris: the endodermal (cyan) and the ectodermal (purple) net. (B) Intraepithelial neurons are randomly scattered between the epithelial cells of the two germ layers. (C) Two types of connections have been found between Hydra’s neurons. (D) Endodermal neurons are in physical touch with each other by forming neural handshakes by digiform endings, which get intertwined. (E) In other places, clusters of vesicles of different types can be released to mediate volume transmission between neurons and between neurons and other cells.
