Fox and rabbit in the quantum world

The reproduction number R is often used as an indicator to predict how quickly an infectious disease will spread. researchers have developed a mathematical model that is just as easy to use but enables more accurate predictions than R. Their model is based on a reproduction matrix that takes into account the heterogeneity of society.

Whether tunnels or retaining walls - many Swiss reinforced concrete structures from the 1960s to the 1980s are at risk. Corrosion can make them unstable. ETH start-up Talpa Inspection has now developed a solution to localise corrosion more easily, even in hard-to-reach places.

Twenty volunteers spent six months learning about the scientific method through a citizen-science initiative led by EPFL. The initiative was part of a study to determine how the microplastic particles released by tire wear are affecting lakes and rivers in Vaud Canton.

Scientists from EPFL work on sustainable approaches to soil remediation, like the use of naturally occurring microorganisms that can "eat" pollutants found in soil and the water table.
