Fibres make chaotic turbulence more predictable
Fibres make chaotic turbulence more predictable
The chaotic behaviour of vortices is one of the things that makes weather forecasting so difficult. Researchers at ETH Zurich have now developed a novel experimental method that enables more accurate analyses of the movement of turbulence in fluids. Turbulence is one of the most important and at the same time one of the least understood phenomena in nature.

Reusing shower water
Reusing shower water
An Eawag study has shown that it makes good sense to recover domestic energy, for example from warm shower water. The study refutes concerns that this form of heat utilisation could have a negative impact on waste water treatment plants. In fact, utilising the energy closer to its source reduces energy losses in the waste-water system.

Water management: Deciding despite uncertainties
Water management: Deciding despite uncertainties
How can research support decisions in water management practice, even if much is still uncertain? When managing rivers, for example, the forecasts of what consequences various measures will have are often fraught with uncertainties. It is also not always clear which status is to be achieved in the end with river revitalisation projects, because different stakeholders sometimes pursue different goals, such as recreation, nature conservation, flood protection, fishing or energy generation - and therefore assess possible outcomes in contradictory ways.

Small force, big effect: How the planets could influence the sun
Small force, big effect: How the planets could influence the sun
A new theory supports the controversial hypothesis that the planets affect solar activity. It puts forward a mechanism by which the very small influence of the planets could exert its rhythm on such a large system as the Sun. If the theory is confirmed, it could possibly be used to predict solar activity more accurately.

Towards a more affordable analysis of air pollution
Towards a more affordable analysis of air pollution
Scientists have developed a new method for chemical analysis of fine particles that they plan to extend on a large scale - including in developing countries - through an Innosuisse innovation grant award and a new startup. Satoshi Takahama and Nikunj Dudani, two scientists at EPFL's Laboratory of Atmospheric Processes and their Impacts (LAPI), have developed an innovative system that could replace the array of instruments typically used to measure air quality by a single device small enough to fit in a carry-on bag.

1,200 new glacial lakes discovered
1,200 new glacial lakes discovered
A comprehensive inventory of Swiss glacial lakes shows how the lake landscape in the high mountains has changed since the end of the Little Ice Age. Due to climate change, the glaciers of the Alps are melting. When the sometimes huge ice fields retreat, they often leave behind depressions and natural dams in the exposed landscape.

Planting oats to study the effects of air pollution
A team of scientists turned Bois-Chamblard park in Buchillon, on Lake Geneva, into a temporary research station for collecting experimental data. Their goal is to better understand how anthropogenic air pollution affects plant growth. What role does air pollution play in plant growth? That's the question a cross-disciplinary team of scientists has set out to answer.

Reforestation may help mitigate droughts
Reforestation may help mitigate droughts
Based on observational data from Europe, climate researchers from ETH Zurich have shown for the first time that forests lead to a rise in precipitation. Their analyses also revealed that if the available agricultural land were reforested, the amount of precipitation in Europe could increase by more than 7 percent.

Better planning can reduce the urban heat island effect
Better planning can reduce the urban heat island effect
In his PhD thesis, EPFL researcher MartÝ Bosch proposes a method for spatially quantifying the impact of mitigation measures - planting green spaces and using different building materials - on the urban heat island effect. During hot weather, cities are warmer than the surrounding rural areas. This well-known phenomenon - known as the urban heat island effect - is particularly acute at night when concrete and asphalt release the heat stored up during the day.

Aquatic life underground
Aquatic life underground
Groundwater is also an ecosystem, but little is known about the biodiversity underground. researchers have now documented the diversity of life in Swiss groundwater in a pilot study - and discovered previously unknown species of amphipods in the process. Here they relied on a citizen science approach.

New model simulates the tsunamis caused by iceberg calving
A team of scientists has developed a new model for simulating both iceberg calving and the tsunamis that are triggered as a result. Their method can help improve hazard assessment in coastal areas and refine the empirical calving models used to evaluate rising sea levels. Johan Gaume, an EPFL expert in avalanches and geomechanics, has turned his attention to ice.

Mixed cultures for a greater yield
Mixed cultures for a greater yield
What holds true for meadows would seem to apply to arable land, too: mixed cultures are more fruitful than monocultures. This was the outcome of an ETH Zurich research project led by Christian Sch÷b. Monocultures dominate arable land today, with vast areas given over to single elite varieties that promise a high yield.

Harvesting drinking water from humidity around the clock
Harvesting drinking water from humidity around the clock
Researchers at ETH Zurich have developed a condenser for countries where water is in short supply. Theirs is the first zero-energy solution for harvesting water from the atmosphere throughout the 24-hour daily cycle. It relies on a self-cooling surface and a special radiation shield. Fresh water is scarce in many parts of the world and must be obtained at great expense.

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.
