Reconfigurable Curved Beams at Terahertz Frequencies Using Inverse‐Designed Bilayer Diffractive Structures

open access: yesAdvanced Photonics Research, Volume 7, Issue 5, May 2026.
An inverse‐designed bilayer diffractive structure enables reconfigurable propagation of two distinct curved beams via 180° rotation of the second layer. Curved electromagnetic beams at terahertz (THz) frequencies have recently emerged as a powerful example of wavefront engineering, with applications in imaging and high‐capacity wireless communications.

Diminished Signal‐to‐Noise Ratio Disrupts Somatosensory Population Encoding and Drives Tactile Hyposensitivity in the Fmr1−/y Autism Model

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
This study provides a translational approach for linking neural activity to tactile deficits in autism. By combining psychophysics with cortical recordings in a mouse model of autism, we show that low signal‐to‐noise ratio in somatosensory neurons weakens population encoding of fine touch, impairing detection, decoding, and leading to perceptual ...

Shifting Seas, Changing Diets: Evidence of Temporal Dietary Shifts in Marine Megafauna in Southern Brazil (2017–2023)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Understanding the dietary dynamics of marine megafauna is essential for interpreting ecological interactions and assessing environmental changes in marine ecosystems. We analysed temporal trends in the diets of eight megafaunal species, comprising marine mammals, seabirds, and sea turtles.

Integrating biotic interactions in niche analyses unravels patterns of community composition in clownfishes

open access: yesEcological Monographs, Volume 96, Issue 2, May 2026.
Abstract Mutualistic interactions play a fundamental role in shaping species distributions, driving niche differentiation, and structuring communities. Yet their influence on realized niches and patterns of coexistence remains poorly understood. In clownfishes, mutualism with sea anemones underpins their biogeography and ecological success, with ...

Predicting Diabetic Foot Ulcer Outcomes: Machine Learning‐Based Refinement of IWGDF‐Approved Classifications for Outpatient Services

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 3, May 2026.
Six IWGDF‐approved diabetic foot ulcer classification systems were compared using machine‐learning models. SINBAD and UTWCS showed the strongest prediction of poor outcomes, while a modified WIFI system using simplified wound‐depth grading further improved predictive performance in outpatient care. ABSTRACT Introduction This study aimed to validate and
