Researchers have developed a new generation of microelectrode-array chips for measuring nerve impulses, enabling studies of how thousands of nerve cells interact with each other. For over 15 years, ETH Professor Andreas Hierlemann and his group have been developing microelectrode-array chips that can be used to precisely excite nerve cells in cell cultures and to measure electrical cell activity.

Researchers at ETH Zurich - in collaboration with colleagues from EPFL in Lausanne and Harvard Medical School - have developed a system that allows them to optically stimulate individual nerve fibres in living mice. Through this process, they have demonstrated that the nervous system has a direct influence on the immune system.

Marine heatwaves are human made
Heatwaves in the world's oceans have become over 20 times more frequent due to human influence. This is what researchers from the Oeschger Centre for Climate Research at the University of Bern are now able to prove. Marine heatwaves destroy ecosystems and damage fisheries. A marine heatwave (ocean heatwave) is an extended period of time in which the water temperature in a particular ocean region is abnormally high.

Post-Lockdown: No Clustering of Coronavirus Infections in Zurich Schools prior to Summer Break
The University of Zurich tested 2,500 schoolchildren in the Canton of Zurich to determine if they were infected during the period between the onset of the novel coronavirus and early June 2020. The preliminary results show that in the first stage of testing prior to the summer break, there was no clustering of coronavirus infections in schools in the Canton of Zurich.

Researchers develop new method to print tiny, functional organs
Researchers at EPFL have developed an approach to print tiny tissues that look and function almost like their full-sized counterpart. Measuring just a few centimeters across, the mini-tissues could allow scientists to study biological processes-and even test new treatment approaches-in ways that were previously not possible.

Histone degradation after DNA damage enhances repair
Histone degradation after DNA damage enhances repair
DNA damage can occur anywhere in the genome, but most DNA is wrapped around nucleosomes making it inaccessible to the repair machinery. Researchers from the Gasser group now show that DNA damage induces histone depletion, which increases the accessibility and flexibility of the DNA fiber and enhances the rate of homology search during repair by homologous recombination.

Nanostructures with a unique property
Nanostructures with a unique property
Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers at PSI have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have succeeded in visualising this phenomenon using neutron scattering.

More effective monitoring of air quality
More effective monitoring of air quality
Air quality in Switzerland has improved but is still not good enough. To continue the monitoring of air pollutants which has taken place for many years in Dübendorf, canton Zurich, federal government has opened a new station as part of its National Air Pollution Monitoring Network (NABEL). As well as showing whether air pollution control measures are working, it will also be used as a platform for research activities on new measuring equipment or new air pollutants.

Viruses could become harder to kill
Viruses could become harder to kill
A recent EPFL study shows that pathogenic viruses may be able to develop resistance to warm temperatures and some types of disinfectant. That - combined with global warming and more frequent and longer heat waves - could make it even harder to keep them from spreading.  We could soon see the day when people have to think twice before taking a swim in lakes hitherto considered healthy.

Sport and memory go hand in hand
By exploring the benefits of sport in memory and motor learning, scientists from the University of Geneva are opening up promising perspectives for school programmes and in the prevention of Alzheimer's disease. After an intensive sports session, the memory performance are much better. @DR  If sport is good for the body, it also seems to be good for the brain.

EPFL's Predikon: predicting voting results with machine learning
On September 27 Switzerland votes for the first time since the COVID-19 pandemic began, including on a contentious initiative to end the free movement of workers with the European Union. Predikon will be predicting the final outcome within minutes of the release of the first partial municipal results from the Swiss Federal Statistical Office.

Optical Wi-Fi allows for ultrafast underwater communications
EPFL spin-off Hydromea has developed a miniature optical modem that can operate down to 6,000 meters below the ocean's surface. It is sensitive enough to collect data at very high speeds from sources more than 50 meters away. If you want to use a connected device underwater, you don't have many options.

Customising an electronic material
Customising an electronic material
Scientists have gained a fundamental understanding of a highly promising material that could be suited to future data storage applications. Their experiments with strontium-iridium oxide, Sr2IrO 4 , investigated both the magnetic and electronic properties of the material as a thin film. They also analysed how these properties can be systematically controlled by manipulating the films.

Thousands of seismometers on a single cable
Thousands of seismometers on a single cable
Fibre-optic cables are emerging as a valuable tool for geoscientists and glaciologists. They offer a relatively inexpensive way of measuring even the tiniest glacial earthquakes - plus they can also be used to obtain more accurate images of the geological subsurface in earthquake-prone megacities. Today's fibre-optic cables move data at tremendous speeds, enabling us to stream films and TV shows in HD or even 8K resolution.

Biodiversity hypothesis called into question
Biodiversity hypothesis called into question
The trade-off between gleaners and exploiters does not explain the diversity of biological species in the way that scientists expected. Our understanding of biodiversity has to change. Aquatic organisms - and terrestrial ones - that do best when there is lots of food also do best when there is very little .

Comet Chury's ultraviolet aurora
Comet Chury’s ultraviolet aurora
On Earth, auroras, also called northern lights, have always fascinated people. An international consortium involving the University of Bern has now discovered such auroras in the ultraviolet wavelength range at comet 67P/Churyumov-Gerasimenko, Chury for short. This phenomenon was detected thanks to the analysis of data from the European Space Agency ESA's Rosetta mission.

Better catalysts for a sustainable bioeconomy
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, , the researchers advocate paying more attention to the classic zeolites.

Increasing the effectiveness of immunotherapy against skin cancer
Researchers at the University of Bern have discovered a mechanism in the body's own immune system which is responsible for the maturing and activation of immune cells. In the fight against skin cancer, the results have the potential to help immunotherapy succeed, even for patients on whom it previously had no effect.
