Metal‐Support Interaction Triggered Electronic Reconstruction in Pd/CoN‐Co4N Catalysts for Optimizing MEK Oxidation and Poisoning Resistance

open access: yesAdvanced Science, EarlyView.
The strengthened EMSI in Pd/CoN‐Co4N induces electronic rearrangement, generating abundant Pd0 species in situ, modulating the Pd d‐band center to enhance O2 adsorption and MEK activation. Concurrently, it creates numerous Lewis acid sites that preferentially adsorb poisons and shield the active sites.

Thermal Effects of Acoustic-gravity Waves in Titan’s Upper Atmosphere and Their Implications for Atmospheric Jeans Escape

open access: yesThe Astrophysical Journal
Early observations from the Cassini spacecraft revealed the presence of acoustic-gravity waves in Titan’s upper atmosphere. However, the impacts of wave modes with different temporal and spatial scales on the thermal structure and atmospheric escape have

PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression

open access: yesAdvanced Science, EarlyView.
Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

Review of the impact of Martian crustal magnetic fields on its atmospheric ion escape

open access: yes地球与行星物理论评
Mars is the most Earth-like planet in the solar system and one of the most accessible targets for spacecraft exploration. Unlike Earth, Mars lacks a global intrinsic magnetic field and only retains localized crustal magnetic anomalies in the southern ...

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

open access: yesAdvanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Reflation: Redox-Driven Atmospheric Inflation as Tracer of Super-Earth Geochemistry

open access: yesThe Astrophysical Journal Letters
We demonstrate that the redox-sensitivity of mantle outgassing can trigger transient episodes of atmospheric reinflation in highly irradiated and geochemically reduced super-Earths, a mechanism we term “reflation.” Mantle redox governs the outgassing and

Comparative study of global simulation methods and characteristics of the space environments of terrestrial planets

open access: yes地球与行星物理论评
The long-term atmospheric evolution and ion escape of unmagnetized terrestrial planets under continuous solar wind erosion are fundamental to understanding their habitability, water loss mechanisms, and evolutionary pathways. Although Venus and Mars both

CCL3 and IL‐7 Synergistically Enhance CAR‐T Efficacy in Solid Tumors

open access: yesAdvanced Science, EarlyView.
Synergistic delivery of CCL3 and IL‐7 by CAR‐T cells overcomes the immunosuppressive tumor microenvironment by enhancing cell infiltration, survival, and local immune reprogramming. This also establishes positive feedback that amplifies anti‐tumor activity and memory responses in both CAR‐T and endogenous T cells, presenting a robust therapeutic ...

Molecular Mobility of N‐Acetylgalactosamine‐Modified Cyclodextrins on a Polyrotaxane for Highly Efficient Liver Targeting of Antibody Chimeras and Genome‐Editing Ribonucleoproteins

open access: yesAdvanced Science, EarlyView.
Monovalent N‐acetylgalactosamine (GalNAc)‐modified polyrotaxane enables efficient liver targeting by utilizing ligand mobility. The sliding and rotating cyclic components i.e., cyclodextrin in the polyrotaxane dynamically cluster GalNAc moieties, thereby mimicking trivalent interactions with asialoglycoprotein receptors.
