Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets

The Astrophysical Journal
As the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

Discovery of Novel Ferrites for Thermochemical H2 Production Cycle via High‐Throughput Thermodynamic Screening

Advanced Science, EarlyView.
A high‐throughput CALPHAD‐based approach is employed to discover multicomponent ferrites with enhanced H2 yields for thermochemical water splitting. The most promising composition exhibits exceptional redox performance and favorable thermodynamics, with dual redox activity of Fe and Mn.

Abiotic Factors and Plant Communities Shape the Distribution of Soil Pathogenic Oomycetes in Chinese Grasslands

Advanced Science, EarlyView.
The continental‐scale study reveals that soil phosphorus strongly predicts the richness of soil pathogenic oomycetes in Chinese grasslands, while precipitation and plant species richness drive their absolute abundance; modeling predicts ≈42% of grassland areas may face elevated oomycete disease risk under future climate scenarios, especially in typical

An Absolute Mass, Precise Age, and Hints of Planetary Winds for WASP-121A and b from a JWST NIRSpec Phase Curve

The Astronomical Journal
We have conducted a planetary radial velocity measurement of the ultrahot Jupiter WASP-121b using JWST NIRSpec phase curve data. Our analysis reveals the Doppler shift of the planetary spectral lines across the full orbit, which shifts considerably ...

UV‐Triggered Cascading Degradation of Silicone Elastomer via Self‐Fluoride Amplification

Advanced Science, EarlyView.
UV‐triggered degradable materials offer proficient control of functional lifetime, while having issues with trigger efficiency. This work enhances the UV‐triggered degradation mechanism of silicone elastomer by introducing the UV‐initiated synergetic fluoride self‐amplification. The silicone composite shows excellent mechanical properties and on‐demand

Zoborg: On‐Demand Climbing Control for Cyborg Beetles

Advanced Science, EarlyView.
A novel on‐demand climbing protocol enables Zoborg (a cyborg beetle from the living Zophobas morio) to seamlessly transition from horizontal floors to vertical walls. Multiple unrestrained mechanosensors allow wall sensing while electrical stimulation of the elytron initiates climbing. Leveraging the agile locomotion and exceptional adaptability of the

Bio‐Inspired Strategy for Radiation‐Based Thermal Management and Utilization

Advanced Science, EarlyView.
Biological organisms have evolved remarkable strategies to manage and exploit thermal radiation. This review explores bio‐inspired systems that mimic these adaptations—such as radiative cooling, thermal regulation, thermal insulation, water harvesting, infrared camouflage, and infrared detection—and highlights their application in thermal management ...
