Terrestrial Runoff Divides the Central Arctic Ocean and Shapes the Biologically Relevant Marine Lightscape

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic Ocean is undergoing drastic changes in its sea ice cover, but is also optically complex. Observations from summer 2022 across the western Eurasian Basin, show increased colored dissolved organic matter (CDOM) absorption from terrestrial‐derived runoff within the Transpolar Drift (TPD) in the Amundsen Basin, extending down to a depth

Mixing at the Margins Drives Nitrate Delivery During Downwelling

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Wind‐driven coastal upwelling delivers nutrients to the surface waters and enhances primary productivity. In contrast, downwelling transports nutrient‐depleted water away from the surface and is usually presumed to decrease primary production. Here, we show that processes during downwelling can actually pump nutrients into previously nutrient ...

Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).

Sus1 Modulates Chromatin Remodeling and Gene Expression via the Cell Wall Integrity Pathway in Saccharomyces cerevisiae

open access: yesThe FASEB Journal, Volume 40, Issue 9, 15 May 2026.
Cell wall stress in yeast triggers transcriptional reprogramming through the CWI pathway. This study identifies Sus1, a subunit of SAGA and TREX‐2, as a key regulator in this process. Sus1 associates with stress‐responsive genes, promoting pre‐initiation complex assembly, chromatin remodeling, and RNA Pol II progression independently of H2B ...
