'Self-cleaning' concrete could keep buildings looking new

Building materials that clean themselves could save immense time and labor in homes and businesses, as well as reduce disease risk in settings such as hospitals. Now, researchers reporting in ACS Applied Materials & Interfaces ...

A remote control for everything small

Atoms, molecules or even living cells can be manipulated with light beams. At TU Wien a method was developed to revolutionize such "optical tweezers".

Discovery of a new type of particle beam instability

Accelerated, charged particle beams do what light does for microscopes: illuminate matter. The more intense the beams, the more easily scientists can examine the object they are looking at. But intensity comes with a cost: ...

Making planets in a rocket

How are celestial bodies created? Aside from philosophical questions, researchers are taking practical steps to investigate the very first moments when planets are born—on a sounding rocket launching from Sweden next week.

Massive photons in an artificial magnetic field

An international research collaboration from Poland, the UK and Russia has created a two-dimensional system—a thin optical cavity filled with liquid crystal—in which they trapped photons. As the properties of the cavity ...
