Keratin–Melanin Complexation Enables Robust, Delamination‐Resistant Feather‐Inspired Structural Color Coatings for Flexible and Curved Substrates

Advanced Materials Interfaces, EarlyView.
Providing mechanically robust structural color coating technology inspired by cooperative interactions in nature. The spatial arrangement of melanin particles within the keratin matrix generates angle‐independent structural colors. Diverse functional groups in keratin and melanin contribute to interparticle and substrate adhesion, resulting in the ...

Unpacking response Inhibition in animals – part 2: an empirical test

Animal Cognition
Response inhibition - the ability to suppress or stop actions - is crucial for adaptive behaviour across species. In Part 1 of this study, we presented a conceptual framework for understanding response inhibition as multifaceted.

To peck or not to peck: the influence of early-life social environment on response inhibition and impulsive aggression in Japanese quails

Royal Society Open Science
Deficits in response inhibition (RI; i.e. the ability to suppress inappropriate responses) may contribute to increased impulsive aggression (IA; i.e. unplanned behaviours that harm others).

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Unpacking response inhibition in animals – part 1: a conceptual framework

Animal Cognition
Response inhibition - the ability to suppress or stop actions - is crucial for adaptive behaviour across species. The concept of response inhibition has traditionally been regarded as a unidimensional psychological ability.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Dispersal and Mortality of Eastern Imperial Eagles from Bulgaria

Пернатые хищники и их охрана, 2018
Identification of mortality factors and their significance along with dispersal pattern and spatial distribution of mortality events is essential for applying successful conservation measures for long lived species such as Eastern Imperial eagle (Aquila ...
