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.

Spiral Galaxies as Enantiomers: Chirality, an Underlying Feature in Chemistry and Astrophysics

, 2005
Spiral galaxies are axi-symmetric objects showing 2D-chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in aminoacids ...

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 ...

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain

Applied Research, Volume 4, Issue 6, December 2025.
This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

Landslide preparation by forestry activity in a region of high erosion rates: Waingake Landslide, northeast New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1015-1030, December 2025.
ABSTRACT Northeastern New Zealand’s sedimentary rocks and soils are particularly vulnerable to landsliding, with some of the highest specific sediment yields, globally. In addition to earthquakes, rainfall is considered an important landslide triggering process.

Cloud and Star Formation in Spiral Arms

, 2014
We present the results from simulations of GMC formation in spiral galaxies. First we discuss cloud formation by cloud-cloud collisions, and gravitational instabilities, arguing that the former is prevalent at lower galactic surface densities and the ...

Spiral arm amplitude variations and pattern speeds in the grand design galaxies M51, M81, and M100

The Astrophysical Journal, 1989
In the modal theory of galactic spiral structure, the amplitude of a prominent two-arm spiral pattern should oscillate slightly with galactocentric distance because of an interference between the outward and inward propagating waves. In the stellar dynamical theory, the spiral arm amplitudes should oscillate because of differential crowding near and ...

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, Volume 182, Issue 24, Page 6063-6080, December 2025.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

A hitchhiker's guide to modern, practical cyanobacterial taxonomy

Journal of Phycology, Volume 61, Issue 6, Page 1536-1552, December 2025.
Abstract There has been an explosion of new Cyanobacterial taxa described within the last two decades. Cyanobacteria exhibit incredible ecological versatility and morphological variability, and thousands of species have already been described using “traditional” approaches (e.g., morphological features).
