When Microorganisms decompose organic material in the soil, they actively release CO₂ into the atmosphere. This process is called heterotrophic respiration. A novel model shows that these emissions could surge by up to 40 percent by the end of the century – most significantly in the polar regions.

Optical data communications lasers can transmit several tens of terabits per second, despite a huge amount of disruptive air turbulence. ETH Zurich scientists and their European partners demonstrated this capacity with lasers between the mountain peak, Jungfraujoch, and the city of Bern in Switzerland. This will soon eliminate the necessity of expensive deep-sea cables.

Our visual perception depends more strongly on the utility of information than previously thought. This has been demonstrated in a series of experiments conducted by researchers at ETH Zurich and the University of Zurich. Cognitive biases can begin at the retina.

Timber construction is undergoing a renaissance in Switzerland. ETH researchers at the Hönggerberg campus are using a fire simulator to test timber components for the construction of buildings of all sizes. The custom-built oven permits simulations of realistic fire scenarios.
