Positive and relaxed selection associated with flight evolution and loss in insect transcriptomes

GigaScience, 2017
The evolution of powered flight is a major innovation that has facilitated the success of insects. Previously, studies of birds, bats, and insects have detected molecular signatures of differing selection regimes in energy-related genes associated with ...

Untangling Inositol (Pyro)Phosphate Biology Through Emerging Technologies

Advanced Science, EarlyView.
Inositol (pyro)phosphates represent a vital class of intracellular messengers that govern multiple biological processes. The last decade has experienced a surge of interest in the functions of this class of signaling molecules, primarily due to the introduction of several innovative analytical technologies.

A self-sustaining wireless sensing and flight control device for beetles

AIP Advances
Insect-electronics hybrid robots integrate live insects with small electronic backpacks. These backpacks guide insect movement and sense environmental data. Due to size and payload constraints, high-capacity batteries are impractical for prolonged energy

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

Advanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

Evolution, types, and distribution of flight control devices on wings and elytra in bark beetles

Scientific Reports
Gaining the ability to fly actively was a ground-breaking moment in insect evolution, providing an unprecedented advantage over other arthropods. Nevertheless, active flight was a costly innovation, requiring the development of wings and flight muscles ...

Delay of Cucumber Senescence and Life‐Extending Capabilities on Caenorhabditis elegans With the Postharvest Application of Sorbitol and Methyl Salicylate

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Methyl salicylate and sorbitol were taken as coating agents. Caenorhabditis elegans was taken as an animal model. The coated agents were applied in C. elegans. The life span study in C. elegans proves the authenticity of MS and SL. MS and SL extended the post‐harvest life of cucumber for 14 days.

The origin of the odorant receptor gene family in insects

eLife, 2018
The origin of the insect odorant receptor (OR) gene family has been hypothesized to have coincided with the evolution of terrestriality in insects. Missbach et al.

Biomechanics and biomimetics in insect-inspired flight systems

Philosophical Transactions of the Royal Society B: Biological Sciences, 2016
Insect- and bird-size drones—micro air vehicles (MAV) that can perform autonomous flight in natural and man-made environments are now an active and well-integrated research area. MAVs normally operate at a low speed in a Reynolds number regime of 104–105
