The green hairstreak butterfly (Callophrys rubi) gets its blue-green hue from complex nanoscale structures on its wings. The structures, called gyroids, are repeating patterns of spiral-shaped ...

The colours are produced because the scales on the butterfly’s wing behave as diffraction gratings, albeit with a twist. In a normal diffraction grating, the light with the longest wavelengths ...

Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas — a green ...

Green Tech. Solar Panels Might ... These nanostructures absorb and reflect different colors of light at different angles, so the butterfly appears to 'shimmer' and change colors in the air.

TOKYO: Scientists have found that a butterfly species from Australasia has 15 classes of light-detecting cells or photoreceptors, enabling them to see fast moving objects better than the human eye ...

Scientists have genetically engineered a butterfly for the first time, putting a jellyfish protein into a tropical African species so that its eyes fluoresce green.

Galdieria extract, butterfly pea flower, and calcium phosphate are now allowed in a range of foods. ... The FDA Is Replacing Synthetic Food Dyes, and These 3 Just Got the Green Light.

Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas — a green ...
