Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Glacial CO₂ decrease and deep-water deoxygenation by iron fertilization from glaciogenic dust [PDF]

Climate of the Past, 2019
Increased accumulation of respired carbon in the deep ocean associated with enhanced efficiency of the biological carbon pump is thought to be a key mechanism of glacial CO2 drawdown.

Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

Advanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...

A Lagrangian perspective reveals the carbon and oxygen budget of an oceanic eddy

Communications Earth & Environment
Quantifying the ocean’s ability to sequester atmospheric carbon is essential in a climate change context. Measurements of gravitational carbon export to the mesopelagic seldom balance the carbon demand or the oxygen consumption there, suggesting the ...

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, EarlyView.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

Advanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.

Predicting particle catchment areas of deep-ocean sediment traps using machine learning [PDF]

Ocean Science
The ocean's biological carbon pump plays a major role in climate and biogeochemical cycles. Photosynthesis at the surface produces particles that are exported to the deep ocean by gravity.
