Genetic Diversity of Polymyxin Resistance Genes in Klebsiella pneumoniae Clinical Isolates

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT This study investigates the genetic diversity and evolutionary mechanisms driving polymyxin resistance in Klebsiella pneumoniae, a critical priority pathogen. By analysing mgrB, phoPQ and pmrAB genes in susceptible (PM‐S) and resistant (PM‐R) populations through neutrality tests (Tajima D, Fu & Li's D) we uncovered polygenic adaptation and ...

Embracing the politics of transformation: Policy action as “battle‐settlement events”

Review of Policy Research, Volume 43, Issue 1, January 2026.
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.

Exploring the Effects of Ultrasound Processing on Food Packaging Laminated With Aluminum Foil

Polymer Engineering &Science, Volume 65, Issue 12, Page 7136-7147, December 2025.
ABSTRACT This study investigates the effects of ultrasound (US) processing on laminated plastic packaging containing aluminum foil for food contact applications. Two multilayer structures, PET/Al/PE and PET/Al/PP, were exposed to US at 25 kHz and 8.75 W/L for up to 40 min at 25°C and 60°C, using a 3% acetic acid as a food simulant.
