Robotic vehicles capable of transition from aquatic to terrestrial locomotion face considerable challenges associated with propulsive efficiency and performance in each environment. Here we present a morphing amphibious robotic limb that combines the locomotor adaptations of sea turtles for swimming and tortoises for walking. The limb can transform between the streamlined […]
“We took a protein from a snow-making company and modified it,” Paola Camacho, a design student on the grand-prize-winning team from Universidad de Los Andes, told Forbes. “We did research and found that by modifying the protein it would be possible to create ice at high at higher temperatures. Their project, […]
News, Snake infrared detection unravelled
Scientists have discovered the receptors that allow snakes to find prey in the dark. Snakes can ‘see’ in the dark thanks to protein channels that are activated by heat from the bodies of their prey. Vipers, pythons and boas have holes on their faces called pit organs, which contain a membrane that can detect infrared […]
News,How plants tune their greenness to light quality
Scientists are clarifying our understanding of how light wavelengths affect the way plants develop their chloroplasts. Chloroplasts use light from the sun and carbon dioxide to produce energy compounds and are filled with chlorophyll, a pigment that absorbs sunlight to kick off that process and express the color of plants. However, […]
Archer fish, Toxotes microlepis, spit jets of water to capture prey and also hunt by jumping out of the water to heights of up to 2.5 body lengths. In this study, high-speed imaging and particle image velocimetry were used to investigate the kinematics and hydrodynamics of this behavior. Jumping used a set of kinematics in […]
Inspired by the visual system of the mantis shrimp-researchers have created a new type of camera that could greatly improve the ability of cars to spot hazards in challenging imaging conditions. The new camera accomplishes this feat by detecting a property of light known as polarization and featuring a dynamic range […]
Nacre — the iridescent part of mollusk shells — is a poster child for biologically inspired design. Despite being made of brittle chalk, the intricately layered microstructure of nacre gives it a remarkable ability to resist the spread of cracks, a material property known as toughness. Engineers looking to design tougher […]
Paper, Adhesive Nature and Structure of the Gecko Setae
Geckos are excellent at climbing smooth vertical surfaces and their toes are the key to this phenomenon. Research has found that there are a hundred thousand setae, made of Sub-division of beta-keratin, on the toes. These 30–130 µm long seta contain countless 0.2–0.5 µm spatula-shaped […]
News, Scientists Mimic Fireflies to Make Brighter LEDs
The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers from Belgium, France, and Canada studied the internal structure of firefly lanterns, the organs on the bioluminescent insects’ abdomens that flash to attract mates. The […]
Paper, Energetics of optimal undulatory swimming organisms
Fish-like swimming exhibits speeds, efficiencies and versatility relative to body size. Researchers found that minimizing cost of transport (COT) or maximizing swimming speed do not result in optimal efficiency. These efficiencies decrease with swimmer size. Their conclusions explain and bring together past studies about the trade-offs between locomotion and body […]
