Researchers at ETH Zurich have developed a new algorithm that allows them to model the dynamics of physical systems from observations. In the future it could be applied to the onset of turbulence and tipping points in climate.

Bacteria show great promise as a source of active ingredients. Using computer-based genome analysis, researchers at ETH Zurich have now discovered a new class of natural products that might one day serve as antibiotics.

Together with teams from England and Germany, Empa researchers developed a monitoring system for aircraft components. In the future, minor damage could be detected and monitored during flight without the aircraft having to go into the hangar for maintenance. This will reduce operating costs and increase safety at the same time.

Bioengineers at EPFL have found a way to radically increase the efficiency of single-cell RNA-sequencing, a powerful tool that can “read” the genetic profile of an individual cell.

An international team of scientists conducted CALISHTO, a large-scale air measurement campaign in Greece last fall, with the goal of surveying, counting and characterizing the tiny particles and their impact on cloud formation. The goal is to incorporate this information in climate models for improved predictions of clouds, precipitation and climate.

More heat pumps in buildings and more electric cars on the roads will lead to an increase in electricity consumption in Switzerland in the future. To meet this increasing demand, we rely on electricity imports, which, however, often have a large carbon footprint, as they come from gas or coal-fired power plants, for example. In a new study, researchers from Empa and the University of Geneva sketch out various scenarios to show how Switzerland can reduce these CO₂-emitting electricity imports by diversifying the expansion of renewables.

Eawag researchers have won a competition organised by Britain’s National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3R). The prize money is awarded for use in research to develop technologies to replace animal testing.

A team of experts in artificial intelligence and animal ecology have put forth a new, cross-disciplinary approach intended to enhance research on wildlife species and make more effective use of the vast amount of data now being collected thanks to new technologies. Their study recently appeared in Nature Communications.

Wastewater treatment plants are ‘hotspots’ for antibiotic resistance genes and bacteria but sewer overflows exacerbate the problem by disseminating them into rivers. Researchers at Eawag suggest ways to minimise these effects.

ETH Zurich researchers have created artificial colours by 3D printing certain nanostructures inspired by those of a butterfly. This principle can be used in the future to produce colour screens.

Mining can have serious consequences for nature and the health of the population in countries of the Global South, where environmental laws are often only inconsistently implemented. In Hwange, in western Zimbabwe, people have been fighting water pollution from coal mining for years. But they were powerless against the operators – until doctoral student Désirée Ruppen launched a citizen science project in 2018.

Super-insulating materials such as aerogels are expensive. At the same time, they offer a powerful advantage: the thinner the insulation of a building, the larger its usable area. An Empa research team shows when and where, even today, the use of aerogel is already economically viable and ventures an optimistic forecast.

ETH researchers have used computer simulations to show that tissue structure in different types of cancer is decisive in determining how a tumour develops. This information could make it possible to treat patients in a more targeted manner in future.

A system developed by Grégoire Courtine and Jocelyne Bloch now enables patients with a complete spinal cord injury to stand, walk and even perform recreational activities like swimming, cycling and canoeing. 

Can you see sounds? Obviously not. Nevertheless, this Gallery attempts the seemingly impossible, building a visual bridge to the soundscape the ear perceives all around PSI.
