#Synchrotron control room, Yerevan

In 1956, the Soviet physicist Artem Alikhanian began the development of the Armenian accelerator, known as #Arus. His aim was to construct the most powerful electron synchrotron in the world, capable of accelerating particles to nearly the speed of light around a closed loop.
We finally got around to writing an intro article on the "Synchrotron Light" book themes. The article is here

„Interferometric measurement of nuclear resonant phase shift with a nanoscale Young double waveguide“
🥳

A nanoscale X-ray double-waveguide interferometer is developed to measure the phase shift due to the 14.4-keV nuclear resonance of the Mössbauer isotope 57Fe. The phase shift is extracted from just a few single-photon interference measurements using Bayesian inference.
Le clitoris, enfin mis sur la carte
Vingt-huit ans.
C’est le temps qu’il aura fallu pour cartographier précisément le clitoris après l’organe masculin.
Une annonce scientifique ? Oui.
Mais surtout un révélateur.
Car derrière ce retard, il y a une vieille histoire : celle d’un corps féminin longtemps observé, souvent commenté, mais trop rarement étudié avec la même précision.
Pourquoi un organe dédié uniquement au plaisir a-t-il mis si longtemps à sortir du flou ?
Et que dit ce décalage de notre manière de transmettre — ou d’oublier — l’anatomie des femmes ?

"Critical point drying of brain tissue for X-ray phase-contrast imaging", Khan et al. 2026 (Schaefer's and Bosch's labs).

"we propose to replace interstitial material by air to enhance X-ray phase contrast of the ultrastructural features. Critical point drying (CPD) of heavy-metal-stained mouse brain tissue produced samples with preserved ultrastructure, a nanofoam-like material that remains compatible with follow-up conventional resin embedding. Using two synchrotron-based setups [...] we found that CPD samples consistently showed 2–4× stronger phase-shift signal than samples embedded in resin."

X-ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X-ray phase contrast of the ultrastructural features.
