Crystals reveal the danger of sleeping volcanoes

Most active volcanoes on Earth are dormant, meaning that they have not erupted for hundreds or even thousands of years, and are normally not considered hazardous by the local population. A team of volcanologists from the ...

Cable cars could reshape urban landscapes

Cable cars are one of the hallmarks of Switzerland, along with funiculars and paddlewheel boats. They adorn the country's mountaintops like garlands. While cable cars are most often associated with leisure activities in the ...

An underwater glider for measuring turbulence in Lake Geneva

Huge systems of rotating water masses—called gyres—form in oceans and large lakes. Two EPFL laboratories, working with the University of California, Davis, are using an underwater glider to explore one such gyre in Lake ...

Are our lakes on the brink of suffocation?

In order to gain insight into how lakes breathe, EPFL scientists have studied oxygen depletion in the depths of Lake Geneva – the first time such research has been carried out. By collecting key data, they were able to ...

Pinpointing sources of water pollution with a robotic eel

Researchers from EPFL, together with other institutes, have developed a robotic eel that swims through contaminated water to find the source of the pollution. The sensor-equipped robot can be controlled remotely or move on ...

Monitoring phytoplankton growth in lakes from orbit

New research shows how satellite images can be used to improve water quality monitoring campaigns in lakes and provide new insights into local, transient biological processes such as algal blooms.

Tracking micropollutants in Lake Geneva

Antibiotics, urban pesticides, and other contaminants accumulate where wastewater is released into Lake Geneva. Using computer simulations, EPFL researchers have shown that the risk they pose is highest during summer and ...
