There has been a floating laboratory on Lake Geneva called LéXPLORE since 2019. Natacha Tofield-Pasche, limnologist at EPFL and project leader of LéXPLORE, and Damien Bouffard, researcher at Eawag and member of the LéXPLORE steering committee, tell us what is being studied there and why this research platform is unique.

Norway experiences dangerous landslides due to its clay-rich soil. For her Master’s thesis in civil engineering at EPFL, Mathilde Metral outlined steps that the country’s geotechnical engineers can take to improve the predictive computer model they’re currently developing. 

ETH Fellow Nadia Shardt is researching how water droplets in clouds freeze to form ice, and the role played by particles in this process. She has developed an innovative apparatus specifically for this purpose. She hopes that her findings will enable climate models to produce more accurate forecasts.

Researchers at the PSI and ETH Zurich have investigated the extent to which direct capture of carbon dioxide (CO₂) from the ambient air can help to effectively remove greenhouse gases from the atmosphere. The result: With careful planning, for example with regard to location and provision of the necessary energy, CO₂ can be removed in a climate-effective manner. The researchers have now published their analysis in the journal Environmental Science & Technology.
