Following the water cycle in the forest
Following the water cycle in the forest
In the Forest Laboratory "Waldlabor" on Hönggerberg, researchers investigate the storage and transport processes of water in the forest. Recently they showed that forest-floor litter and deadwood have a far larger influence on the forest water balance than expected. The forest on Hönggerberg in the north of Zurich is both, a recreational space and a laboratory.

Lower energy consumption thanks to daylight-saving time
Lower energy consumption thanks to daylight-saving time
The abolition of daylight saving time is a frequently - and hotly - debated topic. Often, only the aspect of electricity consumption due to artificial lighting is considered. In a new study, researchers have analyzed whether daylight saving time also has an impact on the energy needed to heat and cool office buildings, and what role climate change might play in this.

Where should wind turbines be constructed in Switzerland?
Where should wind turbines be constructed in Switzerland?
A study by researchers at ETH Zurich shows for the first time how a relaxation of Swiss spatial planning policy would affect the locations of wind turbines. If the aim is to have as few wind turbines as possible in the Alps and in Switzerland in general, it would be worth considering using windy agricultural areas on the western Swiss Plateau.

New maps chart our affective relationship with the local environment
New maps chart our affective relationship with the local environment
Researchers have studied Vernier, a city in the canton of Geneva, as the pilot site for an interactive map that explores our relationship with the built and natural environments. "Vernier is an odd place. You pass by oil storage tanks, an Ikea, and an airport - and then suddenly you're walking by cows, the Rhône, and little boats." That's how one resident describes what he sees on his daily walking commute.

Dwarf and giant species are most at risk of extinction
Dwarf and giant species are most at risk of extinction
Islands are biodiversity hotspots and are home to animal species with unique characteristics, including dwarf specimens, which have evolved to very small sizes compared to their mainland relatives, and giants. An international study now reports that these species are at higher risk of extinction. The findings are supported by software developed by Daniele Silvestro of the Swiss Institute of Bioinformatics (SIB) at the University of Fribourg.

An internal thermometer tells the seeds when to germinate
An internal thermometer tells the seeds when to germinate
A team from the University of Geneva has discovered the mechanisms by which the seed decides to remain in 'hibernation' or to trigger its germination depending on the outside temperature. Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable.

A wholly sustainable plastics economy is feasible
A wholly sustainable plastics economy is feasible
A new study shows what it will take for the plastics industry to become completely sustainable: lots of recycling combined with the use of CO2 from the air and biomass. It is also the image of plastics that need to change. Plastic is everywhere. Our society cannot do without it: plastics have numerous advantages, are extremely versatile, and are also cost effective.

Forest soils lose a lot of carbon after storm damage
Forest soils lose a lot of carbon after storm damage
Forest soils store large amounts of organic carbon. When storms devastate the forest, this carbon is lost and a large part enters the atmosphere as CO2. Mountain forests are particularly vulnerable to such carbon losses, shows a study by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL.

Scientists monitor wildlife to boost preservation efforts
Scientists monitor wildlife to boost preservation efforts
To mark the tenth annual UN World Wildlife Day, we compiled a sample of EPFL research projects that are using technology to protect and preserve wildlife. Everywhere you look, biodiversity is under threat. According to the World Wildlife Fund (WWF), wildlife populations have plummeted by 69% since 1970.

Scientists improve the accuracy of weather and climate models
Scientists from EPFL and the WSL Institute for Snow and Avalanche Research SLF have developed a program that improves the accuracy of a widely used weather forecasting model by incorporating surface phenomena that weren't previously taken into account. Given the challenges associated with climate change and the energy transition, it's essential for weather and climate forecasters to be able to accurately predict what happens to snowfall.

The complex interplay behind great heat
The complex interplay behind great heat
Many regions have suffered from heatwaves in recent years. But exactly how these form is still a matter of debate. Two researchers at ETH Zurich have now found a nuanced answer. Unusually hot weather in India and Pakistan at the end of March; a long, warmer-than-average summer in central Europe; extreme December temperatures in northern Argentina, Uruguay and Paraguay: 2022 was definitely a year of heat waves.

Climate: lessons from the latest global warming
Climate: lessons from the latest global warming
By analysing sediments dating back to the global warming that happened 56 million years ago, a team from the University of Geneva is taking a new look at our climate future. 56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming.

Decentralised water treatment: from motivation to implementation
Decentralised water treatment: from motivation to implementation
Putting decentralised water treatment technologies into practice is not always easy. It often takes many small steps to motivate people to use these technologies. In a recent article, two environmental health psychologists from Eawag summarise in a "Theory of Change" what is known so far about the psychological factors influencing the use of decentralised water treatment technologies and the measures that could promote their adoption.

Alien plant species are spreading rapidly in mountainous areas
Alien plant species are spreading rapidly in mountainous areas
Until now, mountain regions have been largely spared from biological invasions. But a new monitoring study shows that alien plants are spreading rapidly to higher altitudes along transport routes worldwide. Neophytes use roadsides as gateways of entry Humans, whether deliberately or unintentionally, often introduce alien plants in lowlands, then plants spread from their starting point to higher elevations, particularly along roads, which is why the researchers focused on traffic routes.
