How can we secure our gas supply?
Switzerland has no available fossil gas reserves. It also lacks substantial domestic storage capacities, like those used by Germany. Because of this, geopolitical conflicts and crises can lead to supply shortfalls. Synthetic methane could be a way of getting around this dependency. It can be produced sustainably in Switzerland and fed directly into the existing gas grid.

 While the risks from the use of artificial nanomaterials have been well studied, no project has yet addressed the unintended release of these substances in the event of an accident in the production factory or during transport. (Photo: istock)
Forecast for accidents with nanomaterials
For the first time researchers have estimated the probability of accidental releases of nanomaterials in the future. They based this on models from the nuclear industry. For a risk assessment, the results now have to be linked to information about the hazardous nature of the materials.

Improved accuracy of weather and climate models
Scientists from EPFL and the WSL Institute for Snow and Avalanche Research SLF have developed a program that improves the accuracy of a widely used weather forecasting model by incorporating surface phenomena that weren’t previously taken into account.

 For now, no computer can match the energy efficiency of the human brain. Researchers from Empa, ETH Zurich and the Politecnico di Milano are working to change that. Image: iStock
Novel computer components inspired by brain cells
Researchers at Empa, ETH Zurich and the Politecnico di Milano are developing a new type of computer component that is more powerful and easier to manufacture than its predecessors. Inspired by the human brain, it is designed to process large amounts of data fast and in an energy-efficient way.

Where do toxins from tobacco attack DNA?
It is known that toxins in tobacco smoke can change our DNA – but where exactly in the genome they do this has been a mystery. A new approach developed by researchers at ETH Zurich now brings light into the darkness. In the future, this could make it easier than ever to determine the safety of many chemical substances.
