A new dual drone can both fly and land on water to take aquatic samples and monitor water quality, for example. The drone was developed by researchers at Imperial College London and Empa and recently tested together with researchers at the aquatic research institute Eawag for the first time on Lake Zurich.

According to two recent studies carried out as part of the Vanishing Glaciers Project, the ecosystems of glacier-fed streams are undergoing profound change around the world. That could have major repercussions on the food chain and the natural carbon cycle.

Eawag researchers are using computer algorithms to predict the toxicity of chemicals to fish. Machine learning can help set priorities for experiments and, in the longer term, enable a tremendous reduction of animal testing.

Researchers have developed a new method that uses artificial intelligence to analyse animal behaviour. This opens the door to longer-term in-depth studies in the field of behavioural science – while also helping to improve animal welfare. The method is already being tested at Zurich Zoo.

Plastic waste is now polluting all of the world's ecosystems, even those located far from civilisation. The impact of this on the food chain is still unclear. A laboratory study by the Swiss Federal Institute for Forest Snow and Landscape Research WSL published in iForest has now shown that forest trees also take up plastic particles through their roots and transport them to the above-ground tissues of the plant.

Human geographer Christine Eriksen and physicist David Bresch conduct research into weather and climate risks. Their methods may be different, but they agree that the scale of a disaster is often determined more by societal decisions than by the natural hazard itself.  

EPFL scientists discuss the possibility of offering personalized treatment for chronic lymphocytic leukemia by regulating the expression of a gene known for its “anti-tumorous” properties.

An international research team use a global sampling of seawater to reveal which tropical reef fish occur where. To identify species and families, they successfully used the residual DNA shed by the animals present in the water. But not all fish can be traced in this way.

Failing to perform an experiment, considering the wrong hypothesis, having a paper rejected: failure is not only normal in science, it is also essential for cutting-edge research. What is the experience of researchers in the ETH Domain with this sensitive topic?

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.  

A cell’s production of fat molecules can be a key factor in determining what that cell will become, show scientists at EPFL.

Chlorination of drinking water reduces infections – and it changes the composition of the intestinal flora of young children, as a study published recently in “Nature Microbiology” shows. The results indicate that the diversity of the intestinal flora isn’t reduced and bacteria associated with gut health are increased.

Swiss roboticists and economists from EPFL and University of Lausanne developed a method for estimating the probability of jobs being automated by future intelligent robots and suggesting career transitions with lower risks and minimal retraining effort.

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models.

A research team from ETH Zurich and LMU Munich is using artificial intelligence to analyse 3.2 million development aid projects worldwide. Their research reveals trends and funding gaps.
