The Astrophysical Journal LettersComets are frozen remnants of our solar system’s formation, and comparing their chemical composition to that of planet-forming systems can reveal crucial insights about our origins, potentially answering one of the most challenging questions in planetary

Advanced Science, EarlyView.Periprosthetic joint infection establishes a sophisticated immunosuppressive network between CXCR4+ PMN‐MDSCs and Bregs, inducing profound CD8+ T cell paralysis. Alendronate effectively disrupts this CXCR4+ PMN‐MDSC–Breg axis by targeting STAT3, thereby restoring local immune surveillance.

The Interstellar Heritage of Comets
The Astronomical JournalComets have similar compositions to interstellar medium ices, suggesting at least some of their molecules may be inherited from an earlier stage of evolution.

Advanced Science, EarlyView.Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices
Agribusiness, EarlyView.ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

A JWST Study of the Remarkable Oort Cloud Comet C/2017 K2 (PanSTARRS)
The Planetary Science JournalComets, during their journeys into the inner solar system, deliver volatile gases, organics, and particulates into their comae that provide crucial information for assessing the physicochemical conditions in the outer disk from which they formed. Here we

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells
Advanced Intelligent Systems, EarlyView.Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

Astrophysical Journal, 2019 Since its discovery in the first half of the 20th century, scientists have puzzled over the origins of Titan’s atmosphere. Current models suggest that atmospheric N2 on Titan may have originated from NH3-bearing ice with N-isotopic ratios similar to ...

Advanced NanoBiomed Research, EarlyView.Selenium nanoparticles (SeNPs) are emerging as multifunctional platforms for wound healing, integrating antimicrobial, anti‐inflammatory, and proregenerative activities. This review summarises key mechanisms and recent advances in SeNP‐enabled composite dressings, immunomodulatory nanocomposites, microenvironment‐responsive hydrogels, photothermal and ...
