Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals. [PDF]

Adv Sci (Weinh)
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Sensitivity of Ocean Carbon Sink Estimates to Rare Observations

Geophysical Research Letters
We evaluate the impact of new data in the annual release of SOCATv2024 on air‐sea carbon dioxide (CO2) flux reconstructions. Using the pCO2‐Residual and LDEO‐HPD methods, we reconstruct surface ocean fCO2 based on SOCATv2023 and SOCATv2024.

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

A hydrodynamic and particle-tracking model reveals ENSO-driven dispersal patterns of round scad ichthyoplankton in the Sulu Sea, Philippines

Frontiers in Marine Science
Ichthyoplankton dispersal influences recruitment and sustainability of economically important fish populations. Illegal, unreported, and unregulated fishing has driven recruitment overfishing in the municipal waters of the Sulu Sea.

Factors influencing lake surface water temperature variability in West Greenland and the role of the ice sheet [PDF]

The Cryosphere
Subarctic West Greenland is populated by thousands of seasonally ice-free lakes. Using remotely sensed observations, we analyse the surface water temperatures of six lakes during 1995–2022 to identify factors influencing their variability.

Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

eDNA Collected by Custom‐Built Unmanned Surface Vehicles (USVs) Reveals Spatio‐Temporal Shifts in Tropical Coral Reef Faunal Communities

Environmental DNA
High‐frequency environmental DNA (eDNA) sampling offers new opportunities to reveal fine‐scale biodiversity patterns and short‐term ecological dynamics, yet its spatial representativity and capacity to capture diel shifts in communities remain poorly ...
