A Comprehensive Microscopy Analysis of the Retina of Larus audouinii (Payraudeau, 1826): Environmental and Ecological Insights

Birds
The retinal structure is generally conserved across vertebrates; however, variations occur due to the relationship between environmental factors and visual perception.

Contribution of Seasonal Streams to the Conservation of Native and Migratory Birds in a Coastal Region Undergoing Urbanization

Birds
Urbanization has drastically transformed natural landscapes, threatening biodiversity by reducing species richness and abundance in cities. In this context, seasonal streams serve as refuge areas for various bird species.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Habitat Use of the Hen Harrier (Circus cyaneus) during the Breeding Season in Spain

Birds
Raptors usually show use for a particular habitat to settle during the breeding period. In this study, we aimed to study the habitat use of the breeding populations of Hen Harrier (Circus cyaneus) in Spain, which represents the southern distribution ...

Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...

Considering What Animals “Need to Do” in Enclosure Design: Questions on Bird Flight and Aviaries

Birds
Zoo enclosure design, and housing and husbandry protocols, will always be a compromise between what a species has evolved to do and what is possible to offer in a human-created environment.

An Aptamer‐Based EXACT Anticoagulant as a Sustainable, Animal‐Free Alternative to Unfractionated Heparin

Advanced Science, EarlyView.
By simply conjugating thrombin's active‐site inhibitor, dabigatran, with an exosite inhibitor, aptamer HD1, the resulting EXosite‐ACTive site (EXACT) inhibitors show two orders of magnitude higher potency and selectivity via synergistic binding, while maintaining the aptamer's antidote‐reversible trait, yielding a potential substitute for the animal ...
