Did you know that Acanthamoeba form backpacks of captured Listeria bacteria prior to phagocytosis? In a fruitful collaboration with the Laboratory of Food Microbiology, we characterized this fascinating predator-prey interaction and discovered that random encounters, enhanced by bacterial motility, and Acanthamoeba locomotion drive the predation and backpack formation of Listeria bacteria. Check it out in this PNAS publication. Many thanks and congratulations to everyone involved!
In our new work published in PNAS, we predict that cell elongation enhances encounter rates between phytoplankton cells and thus accelerates marine snow formation, a mechanism that potentially explains the rapid clearance of phytoplankton blooms. Thanks to the Wilczek lab for a very fruitful collaboration! Congratulations to everyone involved.
The project IRRIWAM, led by the Subsurface Environmental Processes group (SEP GROUP Eawag-ETH Zurich), showed that irrigation technology is crucial. It contributes more than climate change to how much water evaporates and groundwater accumulates.
This project was funded through the World Food System Center (Competitive Center of ETH Zurich) with support from Coop.
Do you remember the first time you entered a scientific laboratory? Perhaps you recall the excitement, the fascination and a little bit of intimidation and shyness that came with it? For the majority of the girls of the Kangaroo goes Science event, it was the first time in a lab when they came to visit us. With the aim of giving the girls a taste of scientific work, we conducted an interactive workshop with a number of experiments related to our research topics and methods. Together with the girls, we mimicked the flow conditions of microbes in a flume, found the best shapes for slow sinking phytoplankton made of modelling clay models and spied on motile and non-motile phytoplankton to observe the different shapes that plankton species have and how some of them move. In the end, we hope to have given the girls a great first experience in a scientific laboratory and would love to see many of them again at ETH in couple of years!

It’s starting to be a tradition that we redirect our motions from the lab towards the SOLA relay race once a year. Inspired by our research activities, we headed to our starting lines as motorious microbes with a strong taxis (directed motion towards or away from a stimulus) towards the end line. No matter the environmental challenge we faced, whether we had to run under sunlight induced heat, we faced sudden water flow from above or we had to climb steep gradients, we remained motile and showed positive taxis towards the end line. And in the spirit of microbes being social organisms, we chemotaxed (directed motion towards a chemical gradient, i.e. food) to the potluck dinner to celebrate the successful day together.

A few days ago a review paper lead by Johannes and Francesco on the ecological roles of bacterial chemotaxis was published in Nature Reviews Microbiology. How chemotaxis is performed by bacteria is much better understood than why. In this review, the costs and benefits of chemotaxis are discussed, both for individual bacteria as well as whole populations. This reveals that the function of chemotaxis extends much beyond the traditional role of foraging and contributes to efficient colony expansion as well as microbial diversity. Congratulations to everyone involved.
Our paper on the role of eDNA in biofilm streamers formation led by Eleonora was recently published in PNAS. It describes how extracellular DNA (eDNA) is essential to the mechanical stability of the streamers and under what conditions these biofilm structures are formed. Furthermore, it shows how, by controlling eDNA, it is possible to control streamers formation, a potentially relevant finding in the environmental and medical settings. Congratulations to everyone involved.

Elian Lüthy awarded the Culmann Fonds Award 2021 for her Master thesis on fish larvae and hydropeaking
Congratulations to Elian that has been granted the Culmann Fonds Award 2021 from ETH for her outstanding Master thesis entitled: “What are the Pathways? A method to assess habitat shifts for larvae during hydropeaking”. In this study, Elian developed a novel tool for modelling spatial and temporal shifts in suitable habitats for Brown trout larvae during hydropeaking events. This tool can serve as a complementary approach to the set of hydrological and ecological indicators available in the Swiss guidelines for hydropeaking mitigation. Elian’s work was developed in partnership with Kraftwerke Oberhasli AG (KWO), a Swiss hydropower company that has contributed to developing mitigation measures for hydropeaking impacts.
Robert gave a talk about the importance and the ecological costs associated with hydropower operation in Switzerland
In the scope of ETH Unterwegs, Robert was invited to discuss the relevance of his PhD with students at the cantonal school “Seetal” in Baldegg (canton Lucerne). In times of climate change, rising electricity demand and the Swiss decision to phase out nuclear power production, the role of storage hydropower is crucial, but comes at an ecological cost that is still poorly understood.
Our paper on the coupling between microbial degradation of marine particles and their sinking speed, led by Uria, was recently published in Nature Geoscience. This work demonstrates that particles that are sinking faster experience enhanced degradation due to the removal of degradation by-products by flow, letting bacterial enzymes focus on breaking down the particle material itself. A model developed by François showed that this coupling could play a significant role in setting the observed attenuation of carbon flux with depth in the marine environment. Article from ETH here. Also featured in Science News and Views. Congratulations to everyone involved!
