Nanodust particles in the interplanetary medium

Dust particles smaller than about a wavelength of light are abundant in our solar system, created by collisions between asteroids and from the evaporation of comets. As they scatter sunlight, these particles produce the zodiacal ...

Hidden physics make fish glitter

A theory borrowed from physics to understand how electrons move in semiconductors may explain the silvery mirror-like appearance of many fish, recent research suggests.

Graphene plasmons go ballistic

Squeezing light into tiny circuits and controlling its flow electrically is a holy grail that has become a realistic scenario thanks to the discovery of graphene. This tantalizing achievement is realized by exploiting so-called ...
