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.

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.

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.

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.

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.

ETH Zurich researchers have developed a structure that can switch between stable shapes as needed while being remarkably simple to produce. The key lies in a clever combination of base materials.

The Graphische Sammlung ETH Z¨¹rich has digitised over 50,000 artworks and made them freely accessible. Linda Sch?dler, Head of the Graphische Sammlung, explains in an interview why she hopes to do the same with the remaining 110,000.

The creaking of the shimmering Morteratsch Glacier, the rumbling of ash-coloured dams and the steady sloshing of water in grey-blue Zurich reservoirs... In the ¡°Serendipity¡± seminar series of Chair of Landscape Architecture Christophe Girot, researchers and students leave the seminar room to explore how places sound and how they can be explored by ear. They do this using no more than a microphone and an analogue camera.

Being able to try on an outfit virtually to see if it fits would result in fewer returns. Two ETH students are working on making this possible.

Together with her group, Annette Oxenius conducts research on the fundamental mechanisms of the body¡¯s own immune cells as they react to viral infections. The immunologist has now been honoured with the Clo?tta Prize
