Leaf‐Inspired Eutectic Skin With Extreme Fatigue Resistance and Robust Wet Adhesion for Amphibious Epidermal Electronics

open access: yesAdvanced Materials, EarlyView.
Inspired by Acorus calamus leaves, a heterogeneous eutectic skin integrates an aligned fibrous network within a hydrophobic eutectogel matrix. This hierarchical architecture triggers strain‐induced crystallization to achieve exceptional mechanical toughness and durable wet adhesion.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

An Assessment of Anti-Ganglioside Antibodies for the Diagnosis of Avian Ganglioneuritis and Potential Correlation with Gross Lesions, Microscopic Findings and Serologic Titers in Cockatiels Challenged with Parrot Bornavirus

open access: yesAnimals
Avian ganglioneuritis is one of the most widespread diseases of psittacines and is caused by parrot bornavirus (PaBV). It has been suggested that PaBV causes a T-cell-mediated immunopathology comparable to Borna disease virus 1 (BoDV-1).
