A Bio‐Inspired Visual Sensor With UV‐to‐NIR Fusion for Enhanced Recognition in Autonomous Driving Systems

open access: yesAdvanced Science, EarlyView.
Inspired by the sophisticated multilayer retinal architecture found in Pacific salmon eyes, a novel van der Waals heterojunction sensor based on NbNiTe5/BP is designed. Upon illumination at distinct wavelengths of 365 and 820 nm, the device exhibits distinctive bipolar photocurrent responses with opposite polarities. This unique optoelectronic behavior

Polarization Holographic 4D Phenotyping Reveals Nanoplastic Induced Dysfunction in Zooplankton

open access: yesAdvanced Science, EarlyView.
Contaminant‐induced dysfunction in complex aquatic organisms remains difficult to resolve across scales. Polarization Holographic Imaging Microscopy (PHIM) integrates polarization‐sensitive holography with computational volumetric reconstruction for label‐free phenotyping of zooplankton in natural seawater, revealing that nanoplastic stress drives ...

Destabilization of glacial climate by the radiative impact of Atlantic Meridional Overturning Circulation disruptions

open access: yesGeophysical Research Letters, 2016
During each of the dramatic global warmings that ended the Pleistocene ice ages, the Atlantic Meridional Overturning Circulation (AMOC) was disrupted. It is not clear whether this was a contributing cause or simply an effect of deglaciation. Here we show

Covert Optical Fingerprints Within Overt Structural Colors via Cascaded Cavity Resonances

open access: yesAdvanced Science, EarlyView.
Cascaded photonic–plasmonic cavities combine vivid structural colors with hidden stochastic optical fingerprints in a single monolithic platform. Layered cavities control the overt appearance, while disordered nanogap resonances generate covert scattering with limited mutual influence.

Ocean Sciences Award

open access: yesEos, Transactions American Geophysical Union, 1990
The Ocean Science Award is given for “outstanding service to the marine science community. Service may include leadership, management, sharing of data, analysis techniques, or models, as well as facility or instrumentation development. In every case, the service must go well beyond the normal requirements of an individual's job.

Zinc Fingers as Programmable Metalloprotein Scaffolds for Altering Pathogenic Biomolecular Phase Transitions

open access: yesAdvanced Science, EarlyView.
Modular zinc finger (ZF) metalloproteins function as programmable biomolecular scaffolds that modulate pathogenic amyloid assembly. Through direct protein–protein interactions, ZF arrays alter amyloid phase behavior and redirect β‐sheet fibrillization toward nontoxic aggregates.

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

open access: yesAdvanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

High‐Brightness and Ultra‐Long‐Lifetime Spin Quantum Dot Light‐Emitting Diodes Enabled by Efficient Injection of Spin‐Polarized Holes Through a Hybrid Hole Transport Layer

open access: yesAdvanced Science, EarlyView.
This work employs a hybrid hole transport layer to enhance hole transport efficiency, resulting in improved performance for the final device. It achieves an external quantum efficiency of 6.68%, a circularly polarized electroluminescence asymmetry factor of 0.026, and a high luminance of 14,370 cd/cm2, representing the highest luminance reported to ...
