Sustainable clean drinking water solution

ETH postdoc Olivier Gröninger is improving the drinking water supply for people in rural areas of South America with his Openversum project. This benefits not only the families but also the local economy and the climate

Brazil on the wrong track

To protect tropical forests in Brazil, commodities traders have made voluntary commitments to avoid buying soybeans grown in areas that have recently been deforested. Two new studies reveal just how inadequate these guidelines are in protecting Brazil from deforestation and assess the potential effect of implementing the commitments on a much larger scale.

What seismic waves reveal about Martian crust

Following two large meteorite impacts on Mars, researchers have observed, for the first time, seismic waves propagating along the surface of a planet other than Earth. The data from the marsquakes was recorded by NASA’s InSight lander and analysed at ETH Zurich in collaboration with the InSight Science Team. It provides new insights into the structure of the Martian crust.

Magma on Mars likely

Until now, Mars has been generally considered a geologically dead planet. An international team of researchers led by ETH Zurich now reports that seismic signals indicate vulcanism still plays an active role in shaping the Martian surface.

Climate protection benefits the economy

While the economic impacts of climate policy are generally perceived as costs, Anthony Patt proposes the opposite perspective. For Switzerland, converting the energy system and reaching the net-zero target may net benefit the economy, he finds.

Fighting tumours with magnetic bacteria

Researchers at ETH Zurich are planning to use magnetic bacteria to fight cancerous tumours. They have now found a way for these microorganisms to effectively cross blood vessel walls and subsequently colonise a tumour.
