The more connected the world becomes, the greater the demands that data traffic places on communications infrastructure. ETH Pioneer Fellow Marc Reig Escalé and his team develop innovative chips that process information faster than previously possible while requiring even less energy.

Chemical engineers at EPFL have developed a machine-learning model that can predict a compound’s oxidation state, a property that is so essential that many chemists argue it must be included in the periodic table.

In the laboratories of PSI, researchers are producing proteins of the novel coronavirus Sars-CoV-2. The University Hospital of Zurich is using these in a long-term study to investigate how many people in Switzerland have actually been infected with the virus.

In his PhD thesis, EPFL researcher Martí Bosch proposes a method for spatially quantifying the impact of mitigation measures – planting green spaces and using different building materials – on the urban heat island effect.

The Paul Scherrer Institute, in cooperation with the Swiss Federal Institute of Technology in Lausanne EPFL, is establishing a new research division: Scientific Computing, Theory, and Data.

Artificial intelligence and machine learning are key technologies for science, business, and society – but how transparent are their decisions? Andreas Krause, the 2021 recipient of the Rössler Prize and Chair of the ETH AI Center, shares his thoughts on the opportunities and challenges with trustworthy artificial intelligence.

Scientists from EPFL and University of Bern have successfully implanted – in vivo – their first artificial tubular muscle that augments the aorta and assists cardiac function in pumping blood. Based on these results, the Werner Siemens Foundation has provided the green-light for granting an extra 8 million CHF over 8 years to develop artificial muscles for human disorders.

Not only animals and humans host a complex community of microorganisms – plants do this as well. Researchers at ETH Zurich have recently published two new studies that shed light on fundamental aspects of these close – and often overlooked – relationships.

Niko Beerenwinkel, a Professor at the Department of Biosystems Science and Engineering at ETH Zurich in Basel, is working with colleagues from other research institutions to examine wastewater for traces of the coronavirus. He has detected the Delta variant in five out of six Swiss wastewater treatment plants examined, including ones in Zurich and Bern. Recently he spoke with ETH News.

Groundwater is also an ecosystem, but little is known about the biodiversity underground. Eawag researchers have now documented the diversity of life in Swiss groundwater in a pilot study – and discovered previously unknown species of amphipods in the process. Here they relied on a citizen science approach.

From robots that offer solace to algorithms that help judges make fact-based decisions, robotics and machine learning are entering new domains that were once the preserve of humans.

A team of scientists has developed a new model for simulating both iceberg calving and the tsunamis that are triggered as a result. Their method can help improve hazard assessment in coastal areas and refine the empirical calving models used to evaluate rising sea levels.

Today, molecular genetic methods can be used to breed sustainable crops - such as multinutrient rice. Researchers are calling for the risk of new plant varieties to be assessed not on the basis of the breeding method, but on the basis of their characteristics.

Scientists at EPFL and the University of Warwick have used a virus to identify a peptide that can serve the same function as antifreeze proteins. By preventing ice formation, the compound could play a key role in preserving cells and organ transplants and in food conservation.

EPFL scientists are generating oxygen from sunlight, water and semiconducting polymers. They present a promising way towards economical and scalable solar fuel production.
