Improving Agar Plate Image Quality Using a Low‐Cost 3D‐Printed Lightbox: A Proof‐of‐Concept Evaluation for Machine Learning–Assisted Analysis

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
A low‐cost, three‐dimensional‐printed lightbox improved smartphone‐based agar plate imaging by reducing artifacts and enhancing feature visibility. Standardized lightbox images also supported more interpretable QuPath–assisted colony analysis, with exploratory semiautomated counts showing close agreement with manual reference counts.

Isosteric Engineering of Enzymes: Overcoming Activity–Stability Trade‐Offs by Site‐Selective CH → N Substitutions

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Coupling biosynthetic noncanonical amino acid production with genetic code expansion enables site‐specific incorporation of azatryptophans into PET‐degrading enzymes (PETases). By isosteric single‐atom editing of a conserved tryptophan, AzaPETases break the activity–stability trade‐off, delivering higher catalytic efficiency at elevated temperature and

Quantifying Viral Lysis in Microalgae Using Cell‐Free rRNA

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Cell‐free ribosomal RNA (rRNA) dissolved in seawater provides a quantitative proxy for viral lysis in microeukaryotic phytoplankton. Incubation experiments with two distinct host–virus systems revealed marked increases in cell‐free rRNA production per cell, a proxy for lytic mortality, reaching up to 46‐ and 302‐fold relative to noninfected controls ...

A Novel Distributed Sensor Network to Assess Wind Turbine Blade Acoustics for Structural Health Monitoring

open access: yesWind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,
