Characterisation of a Novel Jumbo Lytic Aeromonas dhakensis Bacteriophage P19 and Its Endolysin
Microbial Biotechnology, Volume 19, Issue 1, January 2026.A jumbo, lytic myovirus phage P19 against multidrug‐resistant (MDR) Aeromonas dhakensis was isolated from river water. P19 demonstrated robust lytic activity, high thermal and pH stability (pH 6–10, up to 60°C), and no genes associated with lysogeny, virulence or antimicrobial resistance. ORF_358 of P19 encodes for T4‐type lysozyme.

OBSERVATIONAL EVIDENCE AGAINST LONG-LIVED SPIRAL ARMS IN GALAXIES [PDF]
, 2011 We test whether the spiral patterns apparent in many large disk galaxies should be thought of as dynamical features that are stationary in a corotating frame for ≳ tdyn, as implied by the density wave approach for explaining spiral arms.

Solar Energetic Particle Events During May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Three solar energetic particle (SEP) events originating from solar active region 13664 occurred on 10–16 May 2024, coinciding with a geomagnetic superstorm. Using data from the Geostationary Operational Environmental Satellites and Meteorological Operational satellite‐C, we investigate the energetic proton fluxes and east‐west flux ratios in ...

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Background ExacTrac Dynamic (ETD) is a novel patient positioning and motion management system for radiation therapy that combines surface guidance, thermal imaging, and stereoscopic x‐rays for image guidance. This combination of technology enables both intrafraction monitoring and surface‐based breath hold gating capabilities.

Dynamic Chiral Plasmonic Systems‐Based on Spiropyran Derivatives and Gold Nanorods
Advanced Materials Interfaces, Volume 12, Issue 23, December 8, 2025.Soft chiral plasmonic nanocomposites are prepared by embedding gold nanorods into spiropyran‐based supramolecular gels. The system self‐assembles into helical structures, enabling plasmonic circular dichroism. When illuminated with UV light spiropyran–merocyanine isomerization occurs, inducing reversible nanoscale reorganization and modulation of the ...
