Composition of the sinking particle flux in a hot spot of dinitrogen fixation revealed through polyacrylamide gel traps

Frontiers in Marine Science
Diazotrophs regulate marine productivity in the oligotrophic ocean by alleviating nitrogen limitation, contributing to particulate organic carbon (POC) export to the deep ocean.

Sediment and particulate carbon removal by pipe erosion increase over time in blanket peatlands as a consequence of land drainage [PDF]

, 2006
Land drainage is common in peatlands. Artificially drained blanket peat catchments have been shown to have a significantly greater soil pipe density than intact catchments.

Enhancing the Ultrasonic Welding of Wood Using 3D Printed Lignin Energy Directors

Advanced Science, EarlyView.
Sustainable manufacturing for lightweight structures using ecofriendly materials will be key to reducing material consumption and lowering carbon footprints. Here, an approach is presented to weld wood using ultrasonic vibrations with material at the joint interface to direct energy.

TBK1 Induces the Formation of Optineurin Filaments That Condensate with Polyubiquitin and LC3 for Cargo Sequestration

Advanced Science, EarlyView.
Phosphorylation of Optineurin by TBK1 induces the formation of filaments that condensate upon binding to linear polyubiquitin. Membrane‐anchored LC3 partitions into these condensates, suggesting that phase separation of filamentous Optineurin with ubiquitylated cargo promotes the sequestration of cargo and its subsequent alignment with LC3‐positive ...

Effect of sampling bias on global estimates of ocean carbon export

Environmental Research Letters
Shipboard sampling of ocean biogeochemical properties is necessarily limited by logistical and practical constraints. As a result, the majority of observations are obtained for the spring/summer period and in regions relatively accessible from a major ...

Nutrients Export by Rivers to the Coastal Waters of Africa: Past and Future trends [PDF]

, 2010
We analyze past and future trends in nitrogen (N), phosphorus (P), and carbon (C) export by rivers to the coastal waters of Africa as calculated by the Global Nutrient Export to WaterShed (NEWS) models for the period 1970–2050.

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

Advanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...

Estimating Carbon Flux From Optically Recording Total Particle Volume at Depths Below the Primary Pycnocline

Frontiers in Marine Science, 2019
Optical instruments can rapidly determine numbers and characteristics of water column particles with high sensitivity. Here we show the usefulness of optically assessed total particle volume below the main pycnocline to estimate carbon export in two ...

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium

Advanced Science, EarlyView.
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.
