Lava production at Soufriere Hills Volcano, Montserrat: 1995-2009 [PDF]

, 2010
[1] We estimate that about 1 km3 of andesitic lava has been produced at Soufrière Hills Volcano, Montserrat from 1995 to 2009. There were three major episodes of extrusion, each lasting about 2 to 3.5 years and producing about 280 to 340 M m3 of lava ...

A Dual‐Membrane Biomimetic Nanoplatform Enables Triple‐Modal Therapy Against SARS‐CoV‐2 Through Viral Decoy, Inflammation Neutralizing, and Intracellular RNAi

Advanced Science, EarlyView.
[A&T]MLN is a triple‐modal nanoplatform with siRNA‐loaded LN coated with hybrid ACE2/macrophage membrane. It blocks viral entry, neutralizes IL‐6/IL‐1β/TNF‐α, and delivers siRNA to suppress viral replication. In a murine lung injury model, it attenuates inflammation, offering a multi‐pronged strategy against SARS‐CoV‐2 variants and hyperinflammation ...

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

Advanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.

PLXDC2 siRNA‐Mediated Intervention Attenuates Microglial Senescence Through cGAS‐STING Signaling

Advanced Science, EarlyView.
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

Advanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.
