Smart homes are intended to make life easier, but logging into individual devices is often still an onerous task. Researchers from ETH Zurich have investigated how everyday routines could be used for secure and user-friendly authentication – with no need for cumbersome passwords.

The European Research Council is supporting the MEMELAND research project of a European research team with over 13.5 million euros. Nathalie Dubois from Eawag is a member of the group. The aim is to provide a new narrative for European environmental history, offering decisive insights for sustainable agriculture and climate protection in Europe.

In times of climate crisis and food shortages, the cultivation of microalgae is a promising solution that could fundamentally change the way we produce animal feed, bioplastics or biofuel. However, the enormous potential is still largely untapped, which is partly due to undeveloped cultivation methods. One of the challenges is to protect the cultures against pests. A new publication by Eawag now shows that co-cultures of different microalgae are more resistant to pests than monocultures.

A secure supply of electricity from renewable energies can only succeed if we also modernise the grid infrastructure. At the Energy Science Centre (ESC), ETH researchers are looking for smart ways to make the electricity grid fit for the energy transition without expensive expansion.

With climate change, hot and dry summers are becoming more frequent, causing water shortages in some regions of Switzerland. Reusing treated wastewater could help to solve this problem. This has been demonstrated by an Eawag team on behalf of the FOEN and some cantons. The researchers also explain what still needs to be done to put the option into practice.
