Noise barriers or improved wheel systems and brakes that are less noisy are not the only ways to reduce railway noise for close-by residents. An inconspicuous component under the tracks is a source of hope for a research team including Empa scientists.

ETH researchers are using artificial intelligence to improve quality management in digital production processes. The team has succeeded in halving the proportion of defective products in an experiment with the semiconductor manufacturer Hitachi Energy.

Researchers from the Paul Scherrer Institute PSI in Villigen have delivered a key component for the ESTIA reflectometer at the European Spallation Source ESS based in Lund, Sweden. When it comes into service in 2026, ESS will be the world’s most powerful neutron source. Switzerland is making a vital contribution to the project. Scientists from across the globe will use ESS instruments to study processes and structures on the atomic scale, advancing materials research to a new level.

An international team led by EPFL scientists, has unveiled a unique quantum-mechanical interaction between electrons and topological defects in layered materials that has only been observed in engineered atomic thin layers. The phenomenon can be reproduced by the native defects of lab grown large crystals, making future investigation of Kondo systems and quantum electronic devices more accessible.

A team of EPFL engineers has discovered a strategy to shape living tissues like dough.
