Angewandte Chemie, EarlyView.Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space
Advanced Robotics Research, EarlyView.A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Ammonia as a Pheromone in Anuran Tadpoles
Physiological Research, 2011 In laboratory experiments, conspecific excretions and ammonia solutions evoked avoidance reactions in tadpoles of three anuran species, Bufo bufo, Rana temporaria, and Rana arvalis. A differential sensitivity of ammonia chemoreception was determined for two anuran species.

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Mechanics of the exceptional anuran ear [PDF]
Journal of Comparative Physiology A, 2008 The anuran ear is frequently used for studying fundamental properties of vertebrate auditory systems. This is due to its unique anatomical features, most prominently the lack of a basilar membrane and the presence of two dedicated acoustic end organs, the basilar papilla and the amphibian papilla. Our current anatomical and functional knowledge implies

Advanced Science, EarlyView.Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.
