Unravelling Marine Benthic Functioning Shifts Under Ocean Acidification
Ecology Letters, Volume 29, Issue 4, April 2026.Ocean acidification is reshaping temperate shallow marine benthic communities and the way they function. Using community transplants at natural CO2 vents, we show that biodiversity loss under declining pH reduces biomass and calcification, while enhancing photosynthesis and nutrient uptake.

Accretion disk wind as explanation for the broad-line region structure in NGC 5548
, 2013 Supermassive black holes in the centers of active galactic nuclei (AGN) are surrounded by broad-line regions (BLRs). The broad emission lines seen in the AGN spectra are emitted in this spatially unresolved region.

The FEBS Journal, Volume 293, Issue 7, Page 2042-2066, April 2026.Calcium‐binding S100 proteins are important mediators of inflammation in humans. Distant members of this family have been recently discovered in teleost fish but their resemblance to human proteins has not been explored yet. This study demonstrates that zebrafish‐specific S100i1 and S100i2 (ictacalcins) possess identical structural organization and ...

Spatial Mismatches of Plant‐Pollinator Interactions Under Future Climate Conditions
Journal of Biogeography, Volume 53, Issue 4, April 2026.ABSTRACT Aim Global change could disrupt critical ecological interactions, especially if interacting species shift their geographic ranges at different rates or in different directions. Functional redundancy within generalized networks could make them more resilient to climate change than networks with highly specialized interactions.
