Dense yet transparent materials offer new way to control light

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to novel ...

Low-reflection wings make butterflies nearly invisible

The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its transparent wings. As a result, ...

'Smart glass' micro-iris for smartphone cameras

A small, low-powered camera component made from a "smart glass" material has been created by a group of researchers in Germany with the hope of inspiring the next generation of smartphone cameras.

New study reveals communications potential of graphene

Providing secure wireless connections and improving the efficiency of communication devices could be another application for graphene, as demonstrated by scientists at Queen Mary University of London and the Cambridge Graphene ...

A robot to beat humans at foosball

At first glance, the foosball table located in the middle of the Automatic Control Laboratory looks perfectly normal. Looks can be deceiving. In defense, one of the levers has a mechanical arm capable of propelling the ball ...

Team uses carbon nanotubes for polarized-light detection

Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of ...
