Researchers use empress cicada wings as a ready-made nanostructure template to enhance surface-enhanced Raman spectroscopy (SERS) performance. The cylindrical nanostructures separated by five-nanometer gaps amplify Raman scattering signals by a factor of a million compared to non-coated cicada wings.
Researchers found that smaller insect wing design, rather than flapping speed, enables them to generate lift and fly. The study showed proportionally longer wings and more force-efficient shape help the smallest species stay airborne.
Researchers discovered a new stage of development during butterfly wing scale growth, finding gyroid structures resemble braids or ropes before becoming smooth. This discovery challenges the previous assumption and offers insights into how complex network-like structures form in butterflies and insects.
A study by the CSIC-UMH Institute of Neurosciences uncovers how flies' flight stabilizers, the halteres, take shape. The structure is stabilized by a sophisticated cellular system that connects its two surfaces through an internal framework.
A recent study suggests that ladybird colors are produced by a combination of pigments and the physical properties of their wingcase. Researchers have discovered structural mechanisms underlying color production and pigment modulation in these insects.
A study from the University of Georgia used museum specimens to track the spread of Ophryocystis elektroscirrha, a parasite affecting millions of monarchs during their annual migration. The research found evidence of infection in the Americas, Europe, Asia, Africa, and Oceania, with limited species affected.
Researchers found that slingshot spiders can listen for approaching insects before releasing their web to catapult forward and capture prey. The spiders use sound-sensitive hairs on their legs to detect the vibrations from the insects' wings, allowing them to deploy their webs in mid-air.
A team of international researchers has discovered a surprising genetic mechanism that influences the vibrant patterns on butterfly wings. An RNA molecule controls where dark pigments are made during butterfly metamorphosis, shaping the butterfly's color patterns in a way previously unforeseen.
Scientists have unveiled that beetles' hindwings are passively deployed and retracted, leveraging the elytra to deploy and retract while flapping forces unfold the wings. This finding has potential applications in designing new microrobots that can fly in confined spaces.
Researchers create detailed wiring diagram of motor circuits in fruit flies, revealing complex nerve coordination for leg and wing movements. The study advances understanding of how the central nervous system coordinates individual muscles for various behaviors.
The study discovered that corrugated wings exhibit larger lift than flat wings when the angle of attack is greater than 30°. The researchers analyzed the flow around a two-dimensional corrugated wing using direct numerical calculations and found a unique airflow dance set off by a distinct corrugated structure.
New research reveals that the Deformed wing virus DWV-A originated in Asia, contradicting previous European origins. The study found that Varroa mites transmitted the virus to European honey bees after their introduction to Asia, leading to widespread infections and colony declines.
Butterflies with smaller or lighter-colored wings, such as those in the Lycaenidae family, are likely to face greater threats from climate change. These species have poorer thermal buffering abilities, which could lead to dramatic declines if temperatures rise.
Researchers at Mainz University and Berlin found a previously unknown function of electrical synapses in the insect neural network, governing wing movement and generating consistent flight power. The discovery reveals new concepts of information processing by the central nervous system.
Washington State University researchers developed a robotic bee that can fly fully in all directions, including twisting motion. The Bee++ prototype achieves six degrees of free movement and is controlled by an artificial brain that acts like an insect's brain.
Researchers used fluid dynamics models to study the mountain pine beetle's flight, finding that wing shape, age, and size impact thrust production. This knowledge can improve statistical confidence levels for insect dispersion studies and help preserve pine forests.
Researchers at MIT have created a way for tiny robots to recover from severe damage to their wings, enabling them to sustain flight performance. The development uses laser repair methods and optimized artificial muscles that can isolate defects and overcome minor damage, allowing the robot to continue flying effectively.
A study found that a small number of Varroa mites can infect many adult honey bees, with high-risk mites spreading pathogens through frequent host switching. This mechanism amplifies the vectorial capacity of Varroa destructor.
Three new hawk moth species have been discovered in The Bahamas, measuring only about the length of a vitamin pill. Their small size is thought to be an adaptation to survive harsh weather conditions such as hurricanes and drought.
Scientists developed a natural antibacterial texture inspired by insect wings, killing up to 70% of bacteria. The innovation aims to reduce food waste, particularly in meat and dairy exports, and extend the shelf life of packaged food.
Researchers have developed a low-cost device to track insect activity, providing insights into their circadian rhythms and behavior. The portable pLAM device can monitor nocturnal species that were previously difficult to track, enabling scientists to study their habits and predict how environmental changes impact them.
Researchers at the University of Bristol identified new mechanisms by which nanopillar structures kill bacteria, including cell impedance and oxidative stress. This breakthrough aims to develop antimicrobial surfaces for biomedical applications, such as medical implants and devices.
A developmental model was constructed to recreate the intricate patterns of secondary veins in insect wings. The study analyzed images from 232 species and found that the model effectively recreated venation patterns across three orders.
Researchers have developed a hybrid origami drone that can switch between stiff and flexible structures depending on the situation. The drone's unique structure allows it to absorb shock upon impact, reducing damage and increasing safety.
Researchers at ETH Zurich developed a self-folding material inspired by the earwig's wing, which can operate without muscular actuation. This innovation has potential applications in space travel, foldable electronics, and everyday objects.
Researchers found distinct protein structures and varying chitin ratios in cicada wings compared to locust wings. This difference may contribute to cicadas' relatively heavy wings, limiting their flight distances.
