Michelle Halbheer started her studies at ETH feeling uncertain. In a video from the "Student Stories" series, she shares how she overcame her initial doubts and reflects on what she would change if she could start over.

When the Earth’s ice masses melt, the way the planet rotates also changes. Researchers at ETH Zurich have now been able to show how climate change is altering the Earth’s axis of rotation and the length of the day. The speed of rotation, which was hitherto mainly influenced by the moon, will now also depend much more on the climate.

Researchers at ETH Zurich have succeeded in detecting heavy precipitation events directly with GPS data. The results of their study could significantly improve meteorological monitoring and forecasting.

In 2019, the tailings dam at a Brazilian iron ore mine failed. The mudslide caused a catastrophe for people and the environment. A team of researchers at ETH Zurich has now uncovered the physical mechanism that may have triggered the accident.

Snow measurement has never been so fast and accurate: ETH Zurich researchers have developed an artificial intelligence capable of determining snow depth across Switzerland using satellite images.

Gravity keeps our feet firmly on the ground and Earth in its orbit around the Sun. Meanwhile, satellites in space measure the acceleration caused by the Earth’s gravitational pull.

Using an artificial neural network, researchers at ETH Zurich have created the first high-resolution global vegetation height map for 2020 from satellite images. This map could provide key information for fighting climate change and species extinction, as well as for sustainable regional development planning.  

The slab avalanche modelling that Alexander Puzrin and Johan Gaume, two researchers from ETH and EPFL, used to explain the so-called Dyatlov Pass mystery has triggered a variety of responses around the world. In a follow-up article, the two researchers reflect on the impact of their research findings in science and the media and describe the follow up expeditions to the Dyatlov Pass that supported the slab avalanche theory.

An electric car that runs on PV power sounds appealing. But is it really possible to enjoy flexibility with a vehicle charged through a home photovoltaic system? An ETH research team has reached some surprising conclusions.

Two scientists in Switzerland solved the mysterious incident. They tell us in the ETH podcast why they got interested in the incident and what happened after they published their findings.

An international research team including scientists from ETH Zurich has shown that almost all the world’s glaciers are becoming thinner and losing mass’ and that these changes are picking up pace. The team’s analysis is the most comprehensive and accurate of its kind to date.

Researchers from EPFL and ETH Zürich have conducted an original scientific study that puts forth a plausible explanation for the mysterious 1959 death of nine hikers in the Ural Mountains in the former Soviet Union.

An extraordinary year is drawing to a close. ETH News takes a look back at the highlights that emerged amidst difficult and unsettling times, at ingenious ideas, fascinating science and solidarity in action during – and despite – the coronavirus pandemic.

Precisely when will the long-lost US aircraft “Dakota” re-emerge from the Gauli Glacier? Radioactive traces from the Cold War now indicate that this will happen soon.

Leading AI researchers from 30 top institutions across Europe are joining forces to form the European AI network ELLIS. Today, it celebrates its launch, with ETH Zurich as a founding member. The ETH Zurich ELLIS Unit is set on establishing the foundations for reliable and trustworthy artificial intelligence.

ETH researchers confirm the paradox: rather than withering during droughts, plants at higher elevations absolutely thrive, as a study just published in the journal Nature Climate Change shows.

The largest glacier in the Alps is visibly suffering the effects of global warming. ETH researchers have now calculated how much of the Aletsch Glacier will still be visible by the end of the century. In the worst-case scenario, a couple patches of ice will be all that’s left.

A unique project is linking in-situ measurements with natural hazards research. For the past ten years, a network of wireless sensors on the Matterhorn’s Hörnli ridge has been constantly streaming measurement data on the condition of steep rock faces, permafrost and prevailing climate. The project leader, Jan Beutel, reviews progress to date.

During the last few years, some of the wreckage of a US Air Force plane that crashed on the Gauli Glacier in 1946 has been salvaged. Model calculations carried out by ETH researchers have now shown that it will probably take another 8 to 16 years for the aircraft’s fuselage to resurface from the ice.

ETH experts in earth sciences and engineering geology have tested out a new method on the Rhone glacier that will allow detailed examination of the interior of the glacier and its movement. The effectiveness of this new technique was better than expected.

Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and Antarctic ice sheets. Their conclusion: previous calculations overestimated the volume of the glaciers in High Mountain Asia.

Fixposition is an ETH spin-off specialising in real-time navigation systems for use in self-driving vehicles, robots or industrial drones. Using a combination of satellite-based positioning systems such as GPS with computer vision technologies, the young entrepreneurs have managed to achieve an unparalleled degree of precision.

An international research team used a computer model to reconstruct the history of glaciation in the Alps, visualising it in a two-minute computer animation. The simulation aims to enable a better understanding of the mechanisms of glaciation.

Hot summers cause glaciers to melt. That not only changes the makeup of the landscape and hence the maps of Switzerland, it also affects every area of society. A new, dynamic glacier inventory makes the impact of climate change and the changing landscape visible.

ETH researchers have confirmed the suspicion that north-facing ice cliffs on debris-covered glaciers in the Himalayas accelerate ice melt.

ETH researchers have identified a rock glacier in canton Valais that is degrading and moving very quickly. Fortunately, it does not present an immediate threat to people and infrastructure.

Digital fabrication techniques for buildings and breathtaking concrete roofs, a heart made of silicone, and a new degree programme in medicine; in 2017, teaching and research at ETH Zurich were characterised by new ventures and a pioneering spirit.

A bed in which you don’t snore and 20 other ETH Zurich research projects with a practical application – Industry Day 2017 offered these inside views. About 600 people from the business community used the platform to engage in an exchange.

ETH scientists have combined millions of images and videos into a three-dimensional, living model of the city of Zurich. The new technology has many possible applications – for example, it can analyse where and when pedestrians are on the move and parking spaces become free.

Cornelius Senn, a measurement engineer in the Department of Civil, Environmental and Geomatic Engineering (D-BAUG), and his post-doctoral colleague Silvan Leinss have developed a new reflector for radar measurements. The underlying mechanism, however, has many possible applications and could revolutionise furniture construction, for example.

Dramatic developments have been documented at the Aletsch glacier, where the ice has retreated at such a pace that an adjoining slope has also started to move rapidly. With the help of a unique dataset, researchers are able to demonstrate a direct connection between the ice loss of the Aletsch glacier and the slippage of the Moosfluh slope.

Giant ice avalanches caused by catastrophic glacier failures are rare events. The collapse of two neighbouring glaciers within two months – as just witnessed in Tibet – was never seen before. The timely analysis of satellite images enabled scientists to issue a warning prior to the second collapse.

ETH’s sixth annual togETHer staff party was held on Friday, 26^th August. It was also a very special occasion for Lorenz Hurni, Professor of Cartography, who was presented with the Golden Tricycle award in recognition of his skill in fostering an optimum balance between work and family life. Arik Jung, President of the Academic Association of Scientific Staff at the ETH Zurich (AVETH), presented him with the award.

Upon application of ETH President Lino Guzzella the ETH Board appointed a total of eight professors and awarded the title of professor to one individual.
