The secret strength of our cell guards

A team of scientists has provided insight into the mechanisms at work in geothermal reservoirs located deep underground, known as supercritical reservoirs. Through a combination of computer simulations and lab experiments, they showed that rocks located between five and eight kilometers deep in the Earth's crust are also permeable to fluids. 

Engineers at EPFL and ETH Zurich have come up with a new approach for reducing traffic congestion in large cities during rush hour. Their system is designed to be both fair and effective. 

Pesticides aren't always necessary: researchers at the University of Zurich have conducted a comprehensive field study showing that damage from herbivores can be reduced by using biodiversity within a plant species. Different plant genotypes can cooperate to help fend off herbivorous insects.

Aquatic invertebrates are used as bioindicators to evaluate the quality of Swiss watercourses. However, climate change is also leading to changes in the species composition of these organisms. Eawag has now investigated the impacts of increasing temperatures on water body evaluations on behalf of the FoeN. The findings: the indicators are expected to remain relevant at least for the coming decades.
