I'm sitting in the last session of the #EZM2026 conference and I'm grateful that I could participate on behalf of @brukercorporation.bsky.social Fluorescence Microscopy. Great trip to my academic past, I was relieved that I still more or less understand what people are working on.

Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

1/10 New preprint on bioRxiv Nanodiamonds for spatial resolution benchmarking in two-photon microscopy We introduce nanodiamond-based phantoms as a robust, reusable alternative to bead–agarose samples for PSF calibration. www.biorxiv.org/content/10.6...
biorxiv.org
Nanodiamonds for spatial resolution benchmarking in two-photon microscopy
Reliable and reproducible measurement of spatial resolution is essential for validating and comparing the performance of two-photon microscopy systems. We present fluorescent nanodiamonds as robust, photostable, reusable, and biocompatible probes for benchmarking spatial resolution. Owing to their nanoscale dimensions and stable fluorescence, nanodiamonds act as near-ideal point-like emitters, enabling accurate characterisation of the point spread function across varying imaging conditions. We demonstrate that nanodiamond-based phantoms serve as a reliable alternative to conventional fluorescent beads embedded in agarose, while at the same time offering advantages in stability and optical properties. Our results position nanodiamond phantoms as a next-generation calibration material that bridges ease of use and reproducibility, advancing quantitative imaging and cross-platform comparability in modern fluorescence microscopy. ### Competing Interest Statement The authors have declared no competing interest.
