Nanostructures and natural patterns have long fascinated researchers in bioinspired materials engineering. Biological samples can be imaged and observed at the nanoscale using sophisticated analytical tools in materials science, ...
(Phys.org)—Researchers have turned to cicada wings to design surfaces with highly antireflective properties, which have potential applications for solar cells, stealth surfaces, antifogging materials, and other optical ...
(Phys.org) -- Most animals move around by using their appendages, such as legs, wings, or fins. But a few exceptional creatures employ rolling as a mode of locomotion. Included in this group are rolling salamanders, spiders, ...
(PhysOrg.com) -- Many trees disperse their seeds by releasing "helicopters," those single-winged seeds that are also called "samaras." As these seeds fall to the ground, their wing causes them to swirl and spin in a process ...
(PhysOrg.com) -- In the past few decades, researchers have been investigating a variety of flying machines. Most studies have focused on improving the flying performance of standard flying mechanisms, rather than developing ...
A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, Jens Højgaard Jensen and colleagues ...

A combined team of researchers from Cornell University and The George Washington University, has characterized the cis-regulatory evolution of the gene WntA in nymphalid butterflies. In their study, published in the journal ...
A trio of researchers, two with Cornell University, the other with Howard Hughes Medical Institute, has discovered the means by which dragonflies are able to right themselves so quickly from an upside-down orientation. In ...
Inspired by the bacteria-killing wings of insects like cicadas, scientists have developed a natural antibacterial texture for use on food packaging to improve shelf life and reduce waste. The lab-made nanotexture from an ...
