A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies

The Astrophysical Journal
We performed N -body/smoothed particle hydrodynamics simulations of isolated spiral galaxies with various bulge-to-disk mass ratios ( M _bulge / M _disk ) from 0.02 to 0.2 to investigate mass transport from galactic scales (10 kpc) down to circumnuclear ...

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Fermi and eROSITA Bubbles as Persistent Structures of the Milky Way

The Astrophysical Journal
The Fermi and eROSITA bubbles (FBs and eRBs), large diffuse structures in our Galaxy, can be the by-products of steady star formation activity. To simultaneously explain the star formation history of the Milky Way (MW) and the metallicity of ∼ Z _⊙ at ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.
