Kineochelins—A New Group of Siderophores From an Antarctic Bacterium

open access: yesMicrobial Biotechnology, Volume 19, Issue 6, June 2026.
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

open access: yesArchaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Leveraging Roadless Areas to Support Strict Protection in the EU

open access: yesDiversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Strictly protected areas exhibit lower levels of disturbance to habitats and species and are central to biodiversity conservation. Yet only 4% of the EU's land is currently placed under strict protection, far below the 10% target set by the EU Biodiversity Strategy for 2030. This study examines the potential of roadless areas to contribute

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

open access: yesThe FEBS Journal, Volume 293, Issue 12, Page 3683-3705, June 2026.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.
