Dark zone of the Greenland Ice Sheet controlled by distributed biologically-active impurities OPEN
Jonathan C. Ryan, Alun Hubbard, Marek Stibal, Tristram D. Irvine-Fynn, Joseph Cook, Laurence C. Smith, Karen Cameron & Jason Box

The surface types that comprise the dark zone of the Greenland Ice Sheet, an area of bare ice with low albedo, are unknown. Here, the authors use UAV imagery to show that, during the melt-season, biologically active surface impurities are responsible for spatial albedo patterns and the dark zone itself.

Here, using GPS and tide-gauge measurements along the Sumatran subduction zone, the authors’ show that a bi-viscous rheology model is needed to explain the stress and strain evolution of the upper mantle following earthquakes.

Turning microplastics into nanoplastics through digestive fragmentation by Antarctic krill OPEN
Amanda L. Dawson, So Kawaguchi, Catherine K. King, Kathy A. Townsend, Robert King, Wilhelmina M. Huston & Susan M. Bengtson Nash

Microplastics are emerging ocean contaminants, but their fates in the ocean environment are poorly understood. Here the authors show that Antarctic krill digest micro plastics into nano plastics, thereby generating particles of a size that can cross biological and physical barriers.

Cation vacancy stabilization of single-atomic-site Pt1/Ni(OH)x catalyst for diboration of alkynes and alkenes OPEN
Jian Zhang, Xi Wu, Weng-Chon Cheong, Wenxing Chen, Rui Lin, Jia Li, Lirong Zheng, Wensheng Yan, Lin Gu, Chen Chen, Qing Peng, Dingsheng Wang & Yadong Li

Development of single-atomic-site catalysts with high metal loading remains a challenge. Here, the authors report a nickel hydroxide nanoboard with abundant Ni2+ vacancy defects serving as the support to achieve high platinum loading by simple wet impregnation.

The oxidized phospholipid oxPAPC protects from septic shock by targeting the non-canonical inflammasome in macrophages OPEN
Lan H. Chu, Mohanalaxmi Indramohan, Rojo A. Ratsimandresy, Anu Gangopadhyay, Emily P. Morris, Denise M. Monack, Andrea Dorfleutner & Christian Stehlik

Non-canonical inflammasome activation is mediated by caspase-11 in mice and caspase-4 in humans. Here the authors show that oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (oxPAPC) competes with LPS for binding to these caspases and in so doing is a negative regulator of non-canonical inflammasome activation in macrophages, but not in dendritic cells.

Mutual potentiation drives synergy between trimethoprim and sulfamethoxazole OPEN
Yusuke Minato, Surendra Dawadi, Shannon L. Kordus, Abiram Sivanandam, Courtney C. Aldrich & Anthony D. Baughn

The antibiotics trimethoprim (TMP) and sulfamethoxazole (SMX) synergistically inhibit bacterial tetrahydrofolate biosynthesis, apparently because SMX potentiates TMP activity. Here, Minato et al. identify a metabolic feedback loop in this pathway, revealing that TMP also potentiates SMX activity.
