Endocytosis-like DNA uptake by cell wall-deficient bacteria
Nature Communications, 2022 Horizontal gene transfer in bacteria can occur through mechanisms such as conjugation, transduction and transformation, which facilitate the passage of DNA across the cell wall. Here, Kapteijn et al. show that cell wall-deficient bacteria can take up DNA

Assembly mechanism of the pleomorphic immature poxvirus scaffold
Nature Communications, 2022 Immature poxviruses are characterized by nonicosahedral semiordered protein scaffolds critical for morphogenesis. Here, the authors use cryo-EM structures of Vaccinia virus D13 scaffold intermediates to explain their assembly mechanism.

Fully automated primary particle size analysis of agglomerates on transmission electron microscopy images via artificial neural networks [PDF]
Powder Technology, Volume 332, 2018, Pages 120-130, 2018 There is a high demand for fully automated methods for the analysis of primary particle size distributions of agglomerates on transmission electron microscopy images. Therefore, a novel method, based on the utilization of artificial neural networks, was proposed, implemented and validated.

Open microscopy in the life sciences: Quo Vadis? [PDF]
arXiv, 2021 Light microscopy allows observing cellular features and objects with sub-micrometer resolution. As such, light microscopy has been playing a fundamental role in the life sciences for more than a hundred years. Fueled by the availability of mass-produced electronics and hardware, publicly shared documentation and building instructions, open-source ...

Electron Microscopy of “premelanin”
Journal of Investigative Dermatology, 1962 Masson's ammonia ted (reduced) silver nitrate technic (1) has been used in studies of the process of melanization. By this method Zimmermann and Becker (2) demonstrated the existence of premelanin in melanoblasts from 10 week old human fetuses. The term premelanin is defined, on the basis of the staining reaction using this method, as the substance of ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
