Study Identifies Practical Limitations of Stealthy Hyperuniform Optical Devices
Researchers experimentally tested 2D stealthy hyperuniform metasurfaces designed to suppress elastic scattering at optical frequencies and found the actual performance fell substantially short of theoretical predictions. Stealthy hyperuniformity is a wave control technique that aims to reduce scattering without requiring periodic order. The findings establish realistic performance bounds and provide design guidelines for implementing this technology in functional optical devices.
A comprehensive experimental and theoretical study of 2D stealthy hyperuniform metasurfaces fabricated via electron-beam lithography reveals significant gaps between theoretical expectations and measured performance. While the metasurfaces did demonstrate pronounced reduction of elastic scattering around the specular direction, the suppression was substantially weaker than predicted by structure-factor calculations based on ideal stealthy hyperuniform point-pattern generators. The researchers systematically identified and quantitatively analyzed the physical origins of this discrepancy, isolating the dominant limiting mechanisms. These results establish realistic performance bounds for the technology and provide practical design guidelines for future implementation of stealthy hyperuniformity in functional devices.

Genetic Drift, Not Selection, Drives Rapid Feather Color Evolution in Island Bird Radiation
A new study of an island bird radiation found that rapid evolution of feather coloration is driven primarily by genetic drift in small populations rather than sexual or ecological selection. The research integrated whole-genome data with detailed plumage measurements across complete species sampling to test whether signaling trait evolution correlates with speciation rates. The findings suggest that neutral demographic processes play a central role in generating phenotypic diversity during island radiations, challenging assumptions about the mechanisms driving rapid evolution.
New AI Model Improves Prediction of Therapeutic Peptide Function from Protein Sequences
Researchers developed a lightweight CNN classifier that predicts whether peptide sequences have therapeutic properties, trained on a database of 54,655 peptides across 48 functional categories. The model uses a novel negative sampling strategy to reduce false positive rates from over 60% in previous approaches to 2.1%. This advancement could accelerate drug discovery by enabling faster computational screening of peptide candidates before expensive experimental testing.
Study Shows Different Metabolic Stress Models Produce Distinct Effects on Human Neuronal Networks
Researchers tested three common in vitro metabolic stress models on human-derived neuronal networks and found each produced different patterns of neuronal activity and cell damage. The models tested were hypoxia alone, oxygen-glucose deprivation (OGD), and hypoxia combined with glutamate exposure. The findings suggest that choice of experimental model significantly affects results and that combining electrophysiological and structural analyses is important for accurately assessing metabolic stress in stroke research.
