“The Same Bullets”: Circuits of Violence and Materialist Solidarity From Rio de Janeiro's Favelas to Occupied Palestine

Antipode, Volume 58, Issue 4, July 2026.
ABSTRACT This paper develops the concept of materialist solidarity: political connection that emerges when peripheralized subjects discover shared position within traceable circuits of violence rather than through sympathetic identification or abstract ideology.

estar: An R package to measure ecological stability

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1090-1100, April 2026.
Abstract Assessing ecological stability is a key task in biodiversity monitoring and conservation. Quantifying stability is not trivial because its different aspects can be measured with various properties. However, to date, no software enables measuring different stability properties on ecological time‐series data.

GNPS Untargeted GC‐MS Metabolomic Analysis of Essential Oils From Duguetia lanceolata and Evaluation of Antimicrobial Activity

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.

Structured Promoter Variability in Epigenetically Regulated Operons Contributes to Surface Adaptation in Salmonella

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
We discovered that Salmonella uses structured, recurrent variation in epigenetically regulated promoter regions to fine‐tune gene expression, revealing a novel evolutionary strategy for surface adaptation. ABSTRACT Bacterial adaptation to dynamic and hostile environments often relies on the ability to modify surface structures, which are subjected to ...

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

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.
