Maps as instruments of power

Lorenz Hurni considers what constitutes maps and why they are also instruments of power – and reveals how the Swiss World Atlas deals with disputed names and unilateral name changes.

Tiny component for record-breaking bandwidth

A modulator developed by researchers from ETH Zurich has broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into the fibre-optic network in a short space of time.

CTRL+ALT+RELAX – or how digital tools help combat work stress

Working in the digital age is increasingly stressful for many people. For Erika Meins, digital technologies and artificial intelligence are both the cause and part of the solution, as they can effectively help reduce stress.

The pupil as a window to the sleeping brain

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during sleep than was previously assumed.

Complete breakdown of Plexiglas into its building blocks

Polymer chemists at ETH Zurich have discovered a surprising way to virtually fully break down PMMA plastic – commonly known as Plexiglas – into its monomer building blocks. The process remains unaffected by the presence of additives.

This nanotube has a nose for oxygen

ETH researchers have developed a low-cost sensor made of carbon nanotubes that can selectively, efficiently and reliably measure minute quantities of oxygen in gas mixtures under light. The detector could be widely used in industry, medicine and environmental monitoring
