Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

The Maize ZmbHLH118 Transcription Factor Regulates Vacuolar Nitrate Loading by the NO3− Transporter ZmCLCa

open access: yesAdvanced Science, EarlyView.
In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

Different Planetary Eccentricity-period (PEP) Distributions of Small and Giant Planets

open access: yesThe Astronomical Journal
We used the database of 1040 short-period (1 ≤ P < 200 days) exoplanets radial-velocity orbits to study the planetary eccentricity-period (PEP) distribution.

Passivation‐Induced Species Dynamics and Microstructural Evolution in Solid‐State Lithium–Sulfur Cathodes

open access: yesAdvanced Science, EarlyView.
The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Tilted Circumbinary Planetary Systems as Efficient Progenitors of Free-floating Planets

open access: yesThe Astrophysical Journal Letters
The dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet–planet interactions.

Vacuum–Laser Fabrication of Programmable Soft Actuators

open access: yesAdvanced Science, EarlyView.
A rapid and accessible fabrication strategy for inflatable soft actuators is presented, combining vacuum sealing with laser cutting of low‐cost thermoplastic pouches. The method enables precise sealing, fast fabrication, and programmable multi‐cell geometries.

Sustainable Phosphorylated Cellulose Nanocrystals: A Dual‐Affinity Platform for High‐Efficiency Enrichment of Intact Glycopeptides and Phosphopeptides

open access: yesAdvanced Science, EarlyView.
AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.

Circumplanetary Disks are Rare Around Planets at Large Orbital Radii: A Parameter Survey of Flow Morphology Around Giant Planets

open access: yesThe Astrophysical Journal
We investigate how the formation and structure of circumplanetary disks (CPDs) vary with planet mass and protoplanetary disk aspect ratio. Using static mesh refinement and a near-isothermal equation of state, we perform a small parameter survey of ...
