- This #FossilFriday we are pleased to have published the new younginid taxon Scyllacerta from the late Permian of South Africa 🇿🇦 This beautiful aggregation has the holotype and has been in the literature for 30 years as “juvenile Youngina”. Photo taken before scanning at the @esrf.fr
- Very excited to share Scyllacerta creanae, a new Permian stem-reptile from South Africa known from an aggregation of several individuals. This specimen provides unprecedented detail regarding the anatomy of the early reptile skull. 🦎 (1/🧵)

- Using high-resolution synchrotron μCT scans from the @esrf.fr, we were able to digitally segment each bone of the skulls (shown here in different colors), allowing their full anatomy to be studied in detail. (3/6)
- Researchers find hints of a multilayered centre of the Earth: High-pressure and -temperature X-ray diffraction experiments at #DESY indicate that seismic anomalies in the Earth's core could be due to chemical layering @springernature.com @esrf.fr @univlille.bsky.social
- Researchers at the Crick, @psich.bsky.social and @esrf.fr have developed a new way to look deeper into brain cell connections by using a particle accelerator and a kind of resin borrowed from the aerospace industry. www.crick.ac.uk/news/2025-11...

- Very excited to continue our amazing collaboration with @apacureanu.bsky.social at @esrf.fr - thank you @wellcometrust.bsky.social and all the collaborators at @crick.ac.uk and @esrf.fr
- Congratulations to @andreas-t-schaefer.bsky.social on receiving a £3.8 million @wellcometrust.bsky.social Discovery Award, working with @esrf.fr, to chart the brain circuity behind the sense of smell in mice. www.crick.ac.uk/news/2025-10...
- Thank you so much @wellcometrust.bsky.social for supporting us to push the the limits of #X-ray #nanoimaging and #connectomics, and to make technology more broadly available to the scientific community! 🙏
- ESRF scientist Alexandra Pacureanu is the recipient of the Wellcome Discovery Award, together with a team at the Francis Crick Institute, to develop X-ray nanoimaging technology to study the mechanisms of information processing in the neural circuits of olfaction. www.esrf.fr/home/news/ge...
- 🥼Shunya Yan is our new postdoc at the Spanish Line of the European Synchrotron (@esrf.fr) in Grenoble, France. 🔅She declares herself passionate about synchrotron facilities...and of Spain too. www.icmm.csic.es/en/new-peopl...
- 👥The team of the Spanish Line of the European Synchrotron (@esrf.fr) in Grenoble (France) is growing. 👩🔬We present you Sylwia Pawledzio, our new beamline scientist at the ICMM. www.icmm.csic.es/en/new-peopl...

- I am proud and grateful to present a dream project today in @nature.com www.nature.com/articles/s41... Meet #Mirasaura grauvogeli, a #wonderreptilewith skin appendages that rival feathers and hairs, challenging our view of reptile #evolution🪶🦎

View full thread#Mirasaura and #Longisquama are #drepanosaurs. These tree-living specialists have bird-like skulls, prehensile tails, and grasping limbs. A typical Triassic weirdo, they perhaps vaguely resembled a pygmy anteater. But it's fair to say, we just made drepanosaurs even weirder!
- We scanned the tiny Mirasaura skull (compressed to be <1 mm(!!) thin) using @esrf.fr synchrotron radiation. It reveals the most bird-like drepanosaur skull to date, with a mostly toothless snout, large forward-facing orbits, and a wide, dome-like skull roof for a sizeable brain

- It is also the first published article coming out of the TR-icOS setup, at the @esrf.fr. And likely the first of many! You can read about the user experience on TR-icOS here: esrf.fr/home/news/ge... (3/3
- Back from beamtime experiment @esrf.fr in Grenoble, investigating bone #metastasis with high resolution #synchrotron #nanoCT together with @xploraytion Berlin. Amazing imaging & team work round the clock, now tons of data to analyse! Thank you! @erc.europa.eu @biogipuzkoa.bsky.social @Ikerbasque

- X-ray nanotomography can be your new friend for neuronal imaging. In our new #preprint (tinyurl.com/nanoXneuro) we present advances that push the spatial resolution limit for X-ray holographic nanotomography (XNH). We can now resolve synapses. 🧵
- Linking function and structure at scale with X-rays - and several times over. Massive congratulations to the team @yuxinzhang.bsky.social, @carlesbosch.bsky.social, @apacureanu.bsky.social @esrf.fr, @crick.ac.uk and all our collaborators.
- My PhD project is out as a preprint! We combined 2P and synchrotron X-ray to understand mouse olfactory bulb circuits, linking physiology to structure in 3 animals! doi.org/10.1101/2025... 🙌 @carlesbosch.bsky.social, @apacureanu.bsky.social, @andreas-t-schaefer.bsky.social, @esrf.fr, @crick.ac.uk

View full threadWe developed our correlative multimodal imaging pipeline to incorporate Synchrotron X-ray Holographic Nanotomography. With it we mapped a targeted 0.3mm^3 volumes with subcellular detail, non-destructively. With sufficient reliability to gather 3 replicates of the same neuronal circuit.
- Big shoutout to all collaborators. Starting with @yuxinzhang.bsky.social, whose PhD evolved building this story. To @andreas-t-schaefer.bsky.social, core PI in this endeavour, and @apacureanu.bsky.social and Peter Cloetens for the expert insight on X-ray holotomography. @crick.ac.uk @esrf.fr
