Where does this contamination come from?

When bodies of water become polluted, it is important to find the cause as quickly and as economically as possible. To this end, TU Wien has now developed a new, DNA-based rapid testing procedure.

Measuring forces of living cells and microorganisms

Forces exerted by a living cell or a microorganism are tiny, often no larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical chocolate bar. Yet, for biological cells ...

Saving Rembrandt for future generations

The surface of many Old Master paintings has been affected by the appearance of whitish lead-rich deposits, which are often difficult to fully characterise, thereby hindering conservation. Painted in 1663, Rembrandt's Homer ...
