Emilia Jarochowska 🇺🇦🌱It's very satisfying to see the crown article of my first PhD student Bryan Shirley published! Skeleton is usually all that remains from an animal in the fossil record, so in order to find out how the animal functioned when alive, we have to squeeze out clues from the skeletal tissues, for example using advanced #ElectronMicroscopy 🔬. We were told that vertebrate tissues are too chemically unstable to study this way, but with the help of experts in microscopy, we were able to make rapid measurements of crystallography in the oldest #vertebrate hashtag#teeth to understand how they function evolved. Turns out the crystal orientation reflects the function! From the #ultrastructure we can estimate how the animals were biting and see their evolutionary adaptations at the level of individual crystals 💎 This was possible thanks to the facilities and funding by EXCITE network and Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation

Sarah Housley“I am acutely aware of the fact that we are building the world for people to live in today, in 30 years, and in a hundred years. We are on the cusp of building a new world – we have the potential to make this incredible technological transformation.” Deb Chachra on how “stopping the catastrophe is just the thing that will happen along the way” #DesignFutures #Infrastructure #Ultrastructure #StoppingTheCatastrophe https://www.scopeofwork.net/an-ode-to-living-on-the-grid/
An Ode to Living on The Grid
An interview with Deb Chachra, author of How Infrastructure Works Deb Chachra is a material scientist and engineering professor at Olin College who writes extensively about infrastructural systems. Astute readers may have noticed that she is one of the thinkers most frequently cited in SOW: I recently referenced her work,
ISEPNew #ISEPpapers #preprint! #MeteoraSporadica, a #protist with incredible cell architecture, is related to #Hemimastigophora: Yana Eglit et al. https://www.biorxiv.org/content/10.1101/2023.08.13.553137v1 #protists #microbes #ultrastructure #protistology #microbiology #science #discovery
"Meteora sporadica is a protist with a unique morphology and motility; cells glide over substrates along a long axis of anterior and posterior projections, and have a pair of lateral ‘arms’ that swing back and forth."

🔥🔥🔥Exciting news! I just published a preprint on the #Ultrastructure of #PrecapillarySphincters and the #NeurovascularUnit. This study is based on the https://www.microns-explorer.org/ dataset by @AllenInstitute. Check 🧵 for more details, including movies of the findings. (1/15)
