Analysing volcanoes to predict their awakening
Analysing volcanoes to predict their awakening
Geologists have reviewed the internal and external mechanisms that trigger volcanic eruptions to better anticipate the potential signs of a future eruption. What causes an eruption? Why do some volcanoes erupt regularly, while others remain dormant for thousands of years? A team of geologists and geophysicists, led by the University of Geneva , Switzerland, has reviewed the literature on the internal and external mechanisms that lead to a volcanic eruption.

Silent witnesses
Silent witnesses
Once of interest only to enthusiasts, ETH Zurich's Entomological Collection now offers researchers a treasure trove of hidden knowledge. Four tightly closed doors protect the Entomological Collection of ETH Zurich from heat and daylight. The cold, dry air is the perfect environment for the two million insects that call these specimen drawers home - although it's not particularly comfortable for their human keepers.

Excess nitrogen puts butterflies at risk
Excess nitrogen puts butterflies at risk
Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation - to the detriment of the butterflies, as researchers at the University of Basel have discovered. More than half of butterfly species in Switzerland are considered to be at risk or potentially at risk.

When hydropower plants emit carbon dioxide
When hydropower plants emit carbon dioxide
Hydropower is considered to be CO2-neutral, but certain power plants in tropical regions produce large quantities of greenhouse gases. Researchers at Eawag have now studied how much carbon dioxide escapes into the atmosphere below the Kariba Dam in southern Africa. Such previously ignored emissions must be taken into account by future carbon budgets.

Chamoli Disaster Could Happen Again
Chamoli Disaster Could Happen Again
Some four months ago, a devastating flood ravaged the Chamoli district in the Indian Himalayas, killing over 200 people. The flood was caused by a massive landslide, which also involved a glacier. Researchers at the University of Zurich, the WSL and ETH Zurich have now analyzed the causes, scope and impact of the disaster as part of an international collaboration.

Research efforts to reduce pesticide contamination
Research efforts to reduce pesticide contamination
With the latest analytical methods, potentially toxic substances can be detected even at very low concentrations. However, the aim of research is not merely to document such contamination but also to understand how it occurs in streams and groundwater, and to propose mitigation measures. In agricultural areas, large volumes of water from fields, roads and paths enter streams via manholes or other artificial drainage systems.

Researchers as bridge builders in water policy
Researchers as bridge builders in water policy
From flood protection and drinking water supply to the revitalisation of water bodies and hydropower production - water policy in Switzerland takes place in a wide variety of sectors. However, the exchange of information between politically divided players is often difficult. Science plays an important role as a bridge builder between the camps.

More than a Third of Heat Deaths Are Linked to Climate Change
More than a Third of Heat Deaths Are Linked to Climate Change
Between 1991 and 2018, more than a third of all deaths in which heat played a role were attributable to human-induced global warming, according to a new study in the Nature Climate Change journal. The study, the largest of its kind, was led by the London School of Hygiene & Tropical Medicine and the University of Bern with partners including Swiss TPH.

Plastic waste in the sea mainly drifts near the coast
Plastic waste in the sea mainly drifts near the coast
A study conducted at the Oeschger Centre for Climate Change Research at the University of Bern provides new insights into the pollution of the world's oceans with plastic waste. The modelling shows that most of the plastic does not end up in the open ocean, but beaches or drifts in the water near the coast.

Microbial biodiversity has a new dimension
Microbial biodiversity has a new dimension
Microbes self-organise to grow into fascinating and complex patterns. The diversity of these patterns depends on a previously unknown factor, as researchers at Eawag have discovered. This might re-define how we view the concept of microbial biodiversity. The microbes in our gut help us digest food, and help us to defend against pathogens.

The waters of the Zambezi: time to act
The waters of the Zambezi: time to act
The Zambezi River Basin in southern Africa is a high-quality waterscape. But current rapid development threatens the waters of the Zambezi, particularly its tributaries. The challenge will be to ensure that mitigation measures keep up with population and economic growth to avoid degradation of water quality degradation.

Online biomonitoring of WWTP wastewater
Online biomonitoring of WWTP wastewater
Treated wastewater can be continuously monitored online with the use of organisms. This gives operators of wastewater treatment plants and discharging industrial companies the ability to respond to acute pollution quickly. The Swiss Waters Protection Ordinance stipulates that substances that pollute water bodies as a result of human activity may not have any deleterious effects on the plants, animals and microorganisms living there or on how the water bodies are used.

Atmospheric inputs of nutrients to soil to decrease in the future
Atmospheric inputs of nutrients to soil to decrease in the future
The shift from fossil to renewable energy sources is essential for climate mitigation but will also significantly reduce the atmospheric input of the nutrients sulphur and selenium into soils. Sustainable solutions are therefore needed to supply intensively used agricultural soils with sufficient nutrients and to ensure a safe and healthy diet for the world's population.

Last ice age: colder than thought
Last ice age: colder than thought
The last ice age, about 20,000 years ago, was significantly colder than previously thought. This is shown for the first time by systematically analysed samples of groundwater collected around the globe and the inert gases dissolved in it. Swiss groundwater from Uster (ZH) also contributed to the results.
