Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Pathogenicity of Beauveria bassiana against Leafcutter Ants Atta laevigata (F. Smith, 1858) (Hymenoptera: Formicidae)

Sociobiology
Leaf-cutter ants are major agricultural pests causing substantial crop losses. Biological control using entomopathogenic fungi offers an eco-friendly alternative to chemical methods.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Ultrastructural and microbial analyses of cellulose degradation in leaf-cutter ant colonies

Microbiology, 2017
Leaf-cutter ants (Atta and Acromyrmex) use fresh leaves to cultivate a mutualistic fungus (Leucoagaricus gongylophorus) for food in underground gardens. A new ant queen propagates the cultivar by taking a small fragment of fungus from her parent colony on her nuptial flight and uses it to begin her own colony.

Locked in Transition: Examining the Role of Paradoxical Tensions in the Transition From Industrial Cluster to Eco‐Clusters

Business Strategy and the Environment, EarlyView.
ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Unleashing the power of visible‐near infrared spectroscopy: predicting Golden Delicious apple enzyme activity

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Enzymatic browning is a significant reaction in fruits that affects their color, appearance, and quality. The quality of apples, as a perishable product, is mainly influenced by the activity of two browning‐related enzymes, polyphenol oxidase (PPO) and peroxidase (POD), during storage.

Leaf endophyte load influences fungal garden development in leaf-cutting ants

BMC Ecology, 2012
Background Previous work has shown that leaf-cutting ants prefer to cut leaf material with relatively low fungal endophyte content. This preference suggests that fungal endophytes exact a cost on the ants or on the development of their colonies.
