Tall trees are crucial for the survival of the Amazon rainforest
Tall trees are crucial for the survival of the Amazon rainforest
An EPFL study has shown that Amazonian trees measuring more than 30 meters are more resistant to precipitation variations than other, shorter trees. This information is key to more accurately predicting how the rainforest, which is an important component of the carbon cycle, will react to climate change.

«Top of Europe
«Top of Europe" for greenhouse gas
The research station at Jungfraujoch is at the top of Europe - and not only because of its unique location. Within the framework of the European research infrastructure «Integrated Carbon Observation System» (ICOS), the laboratory in the heart of the Alps is now officially certified. ICOS provides data to better understand the global carbon cycle and how human activities affect it.

CrowdWater: An App for Flood Research
CrowdWater: An App for Flood Research
The CrowdWater project, developed by doctoral candidates from the Department of Geography of the University of Zurich, is a citizen science project in the area of hydrology, the science of water. The project collects hydrological data on water levels, streamflows and soil moisture from all over the world.

Rumblings deep down in Mars
Rumblings deep down in Mars
On 5 May the lander 'InSight' will commence its journey to Mars from California. Its aim is to gather data to enable a better understanding of the formation and evolution of the Red Planet. One of the key instruments on the NASA mission is a seismometer, which was developed and built under the lead of France together with Germany, Switzerland, the UK and the USA.

Soils in Swiss nature reserves contain significant quantities of microplastics
Soils in Swiss nature reserves contain significant quantities of microplastics
It is one of the first research projects into the existence of microplastics in the soil: Scientists at the University of Bern investigated floodplain soils in Swiss nature reserves for microplastics - and made a find. They estimate, that there are around 53 tonnes of microplastics lying in the top five centimetres of the floodplain.

Climate change drives mountain hares to higher altitudes
Climate change drives mountain hares to higher altitudes
A warming climate will shrink and fragment mountain hare habitat in the Swiss Alps. Populations are likely to decline as a result, concludes an international study led by the University of Bern and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). Specialised species like the mountain hare, adapted to life at high altitudes, are particularly affected by climate change.

University of Basel tests camera for Mars rover
University of Basel tests camera for Mars rover
In 2020, the European Space Agency (ESA) is sending a rover into space to examine the surface of Mars for signs of life. Its on-board equipment includes a high-resolution camera developed in Switzerland, and researchers from the University of Basel are currently testing the camera's operation in an artificial Martian landscape.

Sacrificing ground floors can save lives
Sacrificing ground floors can save lives
Disasters like tsunamis, hurricanes and dam failures are rare but can have devastating consequences on a country. A thesis at EPFL has shown that appropriate construction methods can substantially reduce the impact of such catastrophic events. Davide Wüthrich, a PhD student at EPFL, has just finished his thesis on methods for reducing the damage caused when a wave hits a building.

The ozone layer continues to thin
The vital ozone layer has continued to deplete in recent years over the densely populated mid-latitudes and tropics, while it is recovering at the poles. This is documented by an international research team in the journal Atmospheric Chemistry and Physics. The ozone layer protects life on earth from high-energy radiation.

Evolution of Alpine landscape recorded by sedimentary rocks
Evolution of Alpine landscape recorded by sedimentary rocks
Rock avalanches and torrents started to form V-shaped valleys in the Alps approximately 25 million years ago. This landscape contrasts to the flat and hilly scenery, which characterized the Alps a few millions of years before. Geologists from the University of Bern applied digital technologies to unravel these changes in landscape evolution.

A thermometer for the oceans
A thermometer for the oceans
The average sea temperature is an essential parameter of the global climate - but it is very difficult to measure. At least until now, because an international team of researchers including Empa scientists have now developed a novel method using the concentration of noble gases in the eternal ice. This allows conclusions to be drawn on the changes in sea temperature from the last ice age to the present day, as the researchers report in the current issue of "Nature".

Are our lakes on the brink of suffocation?
Are our lakes on the brink of suffocation?
In order to gain insight into how lakes breathe, EPFL scientists have studied oxygen depletion in the depths of Lake Geneva - the first time such research has been carried out. By collecting key data, they were able to enhance their understanding of the lake's ecosystem and how it is likely to evolve over time.

The oceans were colder than we thought
The oceans were colder than we thought
A team of EPFL and European researchers has discovered a flaw in the way past ocean temperatures have been estimated up to now. Their findings could mean that the current period of climate change is unparalleled over the last 100 million years. According to the methodology widely used by the scientific community, the temperature of the ocean depths and that of the surface of the polar ocean 100 million years ago were around 15 degrees higher than current readings.

Hydroelectric power plants have to be adapted for climate change
Hydroelectric power plants have to be adapted for climate change
Of all the electricity produced in Switzerland, 56% comes from hydropower. The life span of hydroelectric plants, which are massive and expensive to build and maintain, is measured in decades, yet the rivers and streams they depend on and the surrounding environment are ever-changing.

Magma chambers have a sponge-like structure
Magma chambers have a sponge-like structure
ETH researchers show that magma chambers under supervolcanoes are more like soggy sponges than reservoirs of molten rock.

Continental crust thanks to the right mixture
Continental crust thanks to the right mixture
For the first time, ETH scientists have successfully recreated the formation of continental crust in the Archean using a computer simulation. The model helps us to better understand processes that took place three to four billion years ago. The present-day formation of continental crust can be investigated in the framework of plate tectonics; however, it is unclear how continental crust could have formed in the Archean, a period three to four billion years ago, when there was no plate tectonics.

Little Ice Age displaced the tropical rain belt
Little Ice Age displaced the tropical rain belt
Even small changes in global temperature can trigger a migration of the tropical rain belt. This can also lead to climate change, as described by a team of researchers from ETH Zurich and other universities. The tropical rain belt, also known as the Intertropical Convergence Zone (ITCZ), is in a state of constant migration.
