Excited to share our new preprint exploring how Paramecium achieves diverse flow functions, i.e. feeding and swimming, simultaneously. This work was spearheaded by our ExM expert, PhD student Daphne Laan @daphnelaan.bsky.social :

Great to see our paper on light-intensity dependent swimming patterns in #Chlamydomonas out now in Phys Rev Lett. as an Editors' suggestion! With a nice commentary by @philipcball.bsky.social.

From @bdpedigo.bsky.social: a super efficient, highly reliable, and very generalizable method for mesh structure classification, applied here to spine detection across basically every synapse onto a cell in the MICRoNS dataset.

A line plot with the numbers of NSF awards for fiscal years 2021-2026. The curve for fiscal year 2026 is quite a bit lower than those for 2021-2025 while the curve for fiscal year 2026 (in red) is much lower than all through the same date.

Want to come do a postdoc with us?

We’re interested in how sensorimotor function is carried out by the cells and circuits of the spinal cord. We have an awesome team, lots of cool techniques, and we’re open to new ideas/approaches/connections. Get in touch!

Scatter plot with eye sight acuity (measured in cycles per degree) on the y-axis and eye diameter (in mm) on the x-axis.
Birds tend to have higher acuity than mammals at a given eyesight, except anthropoid primates (monkeys and apes) that outperform most birds, except for a few raptors. Some birds of prey (falcons, eagles) exhibit the highest recorded acuity. Corvids cluster between other birds and anthropoids, showing higher acuity than would be expected.

Another bit on eye-sight: I've put together a plot on visual acuity in birds and mammals. Interestingly, corvids seem to have acuity that is a lot better than expected for their eye size/passerines in general. Is anyone aware of structural peculiarities of corvid eyes that might explain that? πŸ§ͺπŸͺΆ

Poster of the EM course in Naples with marine samples. The Electron Microscopy Hands-On Course: sample preparation and imaging of marine environmental samples arises from a very strong and active collaboration between the Stazione Zoologica Anton Dohrn and the EMBL in Heidelberg.
The aim of the course is to provide a theoretical and practical training on electron microscopy starting from the basics to the preparation of samples with high pressure freezing and image acquisition using TEM and SEM.

How about there are _no_ "fundamental" computational units -- these are (useful!) abstractions to help us deal with the computational density of biological matter, which operates across scales. Occasionally, but not always, dynamics from a finer scale unit matter a lot to a courser one.

How do neural circuits generate the walking rhythm?

Using connectome simulations, @sarahpugly.bsky.social found a minimal central pattern generator (CPG) that produces oscillations in leg motor neurons. Same circuit motif for each πŸͺ° leg.
