Beating the heat in the living wings of butterflies

A new study from Columbia Engineering and Harvard identified the critical physiological importance of suitable temperatures for butterfly wings to function properly, and discovered that the insects exquisitely regulate their ...

Dragonflies perform upside down backflips to right themselves

The findings add to current knowledge of how insects fly and keep stable in the air. They could also help to inspire new designs in small aerial vehicles like drones, which can be useful for search-and-rescue attempts and ...

Study reveals unique physical, chemical properties of cicada wings

Biological structures sometimes have unique features that engineers would like to copy. For example, many types of insect wings shed water, kill microbes, reflect light in unusual ways and are self-cleaning. While researchers ...

Nanometric butterfly wings created

A team of researchers from the State University of Pennsylvania (USA) and the Universidad Autónoma de Madrid (UAM) have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. ...

Metals for a new era

Cars that change colour at the push of a button; metals that strengthen with use; buildings that harness energy from the wind... research into designing structural materials that are both responsive and functional is shifting ...

Earwigs and the art of origami

ETH Zurich researchers have developed multifunctional origami structures, which they then fabricated into 4-D printed objects. The design principle mimics the structure of an earwig's wing.
