RNAs Associated With Bacterial Outer Membrane Vesicles: Structural Insights Into Surface Composition

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
This work uncovers a new layer of bacterial communication. We show that RNAs, aided by the Hfq RNA‐chaperone, are not only packed inside Gram negative Outer Membrane Vesicles (OMVs) but can also be embedded in their membranes. This suggests that bacteria may use surface‐exposed RNAs to directly interact with host cells. Overall, our results broaden the

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Watershed land cover predicts the abundance of macroplastic and other anthropogenic litter in streams

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Macroplastic and other types of macroscopic anthropogenic litter (AL; trash, particles > 5 mm) are pervasive across ecosystems, persistent in the environment, increasing in abundance, and can degrade into microplastics (particles < 5 mm). Rivers retain and transform AL prior to export downstream, but improved predictions of AL distribution and movement
