A team from the University of Geneva reveals how three easily measurable parameters provide valuable information about the structure of volcanoes. A step forward in risk assessment and preventive measures. What is the risk of a volcano erupting? To answer this question, scientists need information about its underlying internal structure.
Supplementary family childcare in Switzerland lacks qualified staff. This has a negative impact on both the development of the children and the well-being of the employees. This is shown by a study conducted by the Lucerne University of Applied Sciences and Arts. In Switzerland, a considerable proportion of staff in supplementary family childcare work without formal qualifications.
Elimination of rabies in Africa could be within reach through a more coordinated One Health approach. An innovative study by Swiss TPH and partners applied game theory to tackle rabies challenges and identified effective strategies for affected countries. The paper, published in Nature Communications, demonstrates that a more coordinated approach could end this fatal disease and result in major health, economic and social gains.
An EPFL study carried out in Vaud Canton has shed light on the factors that can prompt people to buy solar panels. It found that having neighbors with solar panels plays a significant role, alongside more well-known influences, such as our social circle. If you're a homeowner, have a high-level job, and have friends or family members with solar panels, chances are that you've got them, too.
The Empa spin-off BTRY wants to revolutionize rechargeable batteries: Their thin-film batteries are not only safer and longer-lasting than conventional lithium-ion batteries, they are also much more environmentally friendly to manufacture and can be charged and discharged in just one minute. For now, the battery is very small, but the founders have big plans for it.
Scientists at EPFL and Charles University have developed a new method to analyze the dynamical, out-of-equilibrium properties of complex disordered systems, such as gold with magnetic impurities or opinions spreading on social media. In physics, a "disordered system" refers to a physical system whose components - e.g. its atoms - are not organized in any discernible way.
Researchers make theoretical breakthrough in thermoelectric material to better harness waste heat for sustainable energy. Around 70% of the energy we use in everyday life is wasted in the form of heat, produced by engines, factories, and electrical devices. However, researchers from EPFL's School of Engineering have made a significant theoretical step forward that could boost sustainable energy generation.
For the first time, researchers combined human and ecological factors to analyse the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
"We will rock you": researchers are developing a gene switch that triggers insulin release in designer cells by playing certain rock and pop songs. Diabetes is a condition in which the body produces too little or no insulin. Diabetics thus depend on an external supply of this hormone via injection or pump.
A study by UNIGE and HUG scientifically demonstrates that exposure to cold outside air is beneficial in reducing the symptoms of croup. For the first time, a scientific study shows that exposure to outdoor cold air is beneficial in reducing the severity of croup symptoms in children, particularly when symptoms are moderate.
Researchers have developed an epoxy resin that can be repaired and recycled, in addition to being flame-retardant and mechanically strong. Potential applications range from coating for wooden flooring to composites in aerospace and railways. Epoxy resins are tough and versatile polymers. In combination with glass or carbon fibers, they are used, for example, to manufacture components for aircraft, cars, trains, ships and wind turbines.
The ability to utilize a mere single alternative food source is all it takes for diarrhoea causing Salmonella bacteria to bloom when a gut is already colonized by a closely related strain, according to researchers from ETH Zurich. This coexistence enables the exchange of antibiotic resistance. Bacteria are growing more resistance to common antibiotics, and one key factor contributing to this problem is the exchange of antibiotic resistance genes between closely related bacterial strains.
For his Master's project at EPFL, Mickaël Achkar compiled data on the movements of dogs to develop a robotic version of the animal that, once set in motion, can run without assistance. Engineers at EPFL's Computational Robot Design & Fabrication Lab (CREATE), headed by Prof. Josie Hughes, are coming up with new ways of building robots possessing never-before-seen capabilities.
Using high precision microfabrication and microfluidics, Clémentine Lipp has developed a tool with the potential to automate T cell screening and sorting-an essential task in immunology. Currently, it is a difficult and laborious process to place two cells in contact with each other to examine their binding characteristics.
Collecting clean water from fog
Researchers at ETH Zurich have demonstrated the use of a specially coated metal mesh to harvest water from fog and simultaneously remove pollutants. People living in dry but foggy areas should benefit from this technology. In countries such as Peru, Bolivia and Chile, it's not uncommon for people who live in foggy areas to hang up nets to catch droplets of water.

A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases - and for those who would like to eat meat, but don't want to kill animals. ETH Zurich Professor Ori Bar-Nur and his team grow muscle cells in the laboratory.
Even though the summer is still in progress - for many birds the migration to the African winter quarters has already begun. Among them is the wheatear, which breeds in mountainous areas. On its 4500-kilometer journey, which takes about 30 days, the small bird can climb to an altitude of more than 5000 meters.
Scientists at EPFL have successfully extended the quantum state lifetime of a mechanical oscillator, a development with vast implications for quantum computing and communication systems. Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems.
A 67-year old patient presenting with oesophageal cancer was treated today at the Paul Scherrer Institute PSI with a form of radiation provided by protons, i.e. positively charged particles. This is the first time this type of radiotherapy has been used in Switzerland to treat an oesophageal tumour.
Quantum technology is promising, but also perplexing. In the coming decades, it is expected to provide us with various technological breakthroughs: smaller and more precise sensors, highly secure communication networks, and powerful computers that can help develop new drugs and materials, control financial markets, and predict the weather much faster than current computing technology ever could.
