Novel gel proves itself to be a highly tunable color filter

Color these scientists happy. An exotic gel they studied at the National Institute of Standards and Technology (NIST) has an unexpected property: The material's temperature determines which color of light can pass through ...

The Milky Way's middle-aged inner ring

Using a combination of observed stars and a realistic model of the Milky Way, scientists at the Max Planck Institute for Extraterrestrial Physics have found a new structure in our home galaxy. Just outside the galactic bar, ...

New chiral nanostructures to extend the material platform

A research team transferred chirality from the molecular scale to a microscale to extend material platforms and applications. The optical activity from this novel chiral material encompasses to short-wave infrared region.

Nature of fast radio bursts clarified

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a fast radio burst after all. The bursts may come from a highly ...

An optical coating like no other

For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings ...
