3D histology of human heart-forming organoids by X-ray phase-contrast tomography

Authors Komorowski K, Reichmann J, Drakhlis L, Zweigerdt R, Salditt T Journal Communications Biology Citation Commun Biol. 2025 Oct 1;8(1):1411. Abstract Three-dimensional (3D) imaging is crucial for elucidating the complex structure of organoid models which involve complex spatial cellular and tissue organization in 3D. While a variety of volume imaging

Pharmacological inhibition of V-ATPase targets mode-switching but not the proton transport cycle

Authors Kosmidis E, Fokaeos M, Shuttle CG, Isselstein MC, Cvjetkovic A, Johnson PJ, Pederesen JL, Jahn R, Preobraschenski J, Stamou D Journal BioRxiv Citation bioRxiv 2025.09.28.679038. Abstract Vacuolar-type adenosine triphosphatases (V-ATPases) are rotary proton pumps that establish proton gradients across cellular membranes. Their pharmacological inhibition is currently under active investigation

Optimal Transport Based Testing in Factorial Design

Authors Groppe M, Niemöller L, Hundrieser S, Ventzke D, Blob A, Köster S, Munk A Journal Arxiv Citation arXiv:2509.13970. Abstract We introduce a general framework for testing statistical hypotheses for probability measures supported on finite spaces, which is based on optimal transport (OT). These tests are inspired by the analysis

Manipulating mitochondrial gene expression

Authors Dahal D, Cruz-Zargoza LD, Rehling P Journal Biological Chemistry Citation Biol Chem. 2025 Sep 15. Abstract Mitochondria are essential for cellular metabolism, serving as the primary source of adenosine triphosphate (ATP). This energy is generated by the oxidative phosphorylation (OXPHOS) system located in the inner mitochondrial membrane. Impairments in
