SLF-scientists Joel Caduff and Yves Bühler trained scientists and practitioners in drone-based snow depth mapping in the Kyrgyz mountains. After packing a lot of equipment including ski touring sets and an eBee-X drone, we boarded the plane to Istanbul on March 29 and then to Biskek, the capital of Kyrgyzstan.
Main Suppliers of Epo in the Human Body Identified
Erythropoietin, or Epo for short, is familiar from doping cases. But the body itself also produces this vital hormone. Now, for the first time, an international research team including scientists has been able to identify the main producer of Epo: a subgroup of kidney cells called Norn cells. The findings could lay the foundation for the development of new therapies.

Despite approved treatments being available, multiple myeloma remains incurable. But researchers at ETH Zurich and University Hospital Zurich set out to improve treatment outcomes by testing hundreds of existing therapeutics outside the body to predict their effectiveness. Multiple myeloma is a rare blood cancer caused by the uncontrolled multiplication of abnormal plasma cells.
Misconceptions Put Women Off STEM Subjects
Young women seem to be less drawn to degrees in science or technology. But what is putting them off? A sociological study at UZH has revealed that outdated gender stereotypes - such as supposed differences in analytical thinking - play a major role. Why do so few female school leavers with good grades in mathematics choose to study a technical subject - despite the high salaries and good employment prospects in the STEM sector? This question has long preoccupied the social sciences, especially as studies show that girls and boys do equally well in mathematics at school.

Preventing the transmission of microbial infections is a global issue. This is especially true in environments where bacteria are easily transmitted through contact with contaminated surfaces. A research team led by the University of Freiburg has developed an antimicrobial coating that reduces the bacterial population by a factor of up to 10,000 within minutes .
In Sweden, immigrants are allowed to participate in regional elections even if they don't have a Swedish passport. Researchers at the University of Basel recently investigated whether this affects naturalization numbers. Their findings could also be of interest for Switzerland. In most countries, the right to participate in the democratic process is reserved for citizens, so anyone who wants to be able to vote must first go through the naturalization process.
Restoration and nature conservation projects have the great potential to restore and maintain important functions of our watercourses for future generations. Researchers from four research institutes of the ETH Domain, in collaboration with the FOEN, have investigated how sediment transport and connectivity affect flood safety and river ecology.
Can ecologically sustainable circuit boards for the electronics industry be produced from cellulose fibers? Empa researcher Thomas Geiger looked into this question. He is now part of a multinational EU project called Hypelignum". Its goal: biodegradable electronics. For many years, Thomas Geiger has been conducting research in the field of cellulose fibrils - fine fibers that can be produced from wood pulp or agricultural waste, for example.
Researchers at EPFL and Vrije Universiteit Brussel have developed a novel and highly efficient method for rapid antibiotic susceptibility testing using optical microscopy. The technique, called Optical Nanomotion Detection, is extremely rapid, single-cell sensitive, label-free, and requires only a basic traditional optical microscope, equipped with a camera or a mobile phone.
Cryo-imaging lifts the lid on fuel cell catalyst layers
Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing how they could be optimized for fuel cell efficiency. Proton-exchange membrane fuel cells (PEMFC), which are being developed for use in electric vehicles, rely on nanoparticles called catalysts to trigger electricity-producing reactions between hydrogen and oxygen.

It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers at ETH Zurich have now succeeded in uniting all of these characteristics in zinc metal batteries. The world needs cheap and powerful batteries that can store sustainably produced electricity from wind or sunlight so that we can use it whenever we need it, even when it's dark outside or there's no wind blowing.
Researchers at ETH Zurich have analysed the bird flu epidemic caused by the H7N9 strain that affected China from 2013 to 2017. New phylogenetic trees will help to improve monitoring of future bird flu epidemics. There are many different bird flu viruses. Besides the subtype H5N1, which has been spreading in the European wild bird population for several years and poses a threat to local poultry farms, there is also, for instance, subtype H7N9.
Researchers at ETH Zurich have created the heaviest Schrödinger cat to date by putting a crystal in a superposition of two oscillation states. Their results could lead to more robust quantum bits and help to explain why quantum superpositions are not observed in everyday life. Even if you are not a quantum physicist, you will most likely have heard of Schrödinger's famous cat.
In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.
Coral reefs are under a growing threat from climate change and human activity, making it more important than ever to understand their strengths and vulnerabilities. A team of scientists has now taken an important step in this direction with the new RECIFS open-access database on reef environments. The Reef Environment Centralized InFormation System ( RECIFS ) is a web application that provides a single repository of all datasets currently available on reef environments worldwide.
Wood is a trump card for the energy transition because it is very versatile and easy to store. Compared to today, up to a third more energy could be obtained from wood, not only in the form of heat, but also in the form of electricity and fuels. However, current use is not efficient enough, Swiss bioenergy researchers have shown in a new report.
Unlike natural opioids, opioid drugs penetrate our cells, which explains both their high efficacy and their side effects, reveals a team from the University of Geneva. The human body naturally produces opioid-like substances, such as endorphins, which block the perception of pain and increase the feeling of well-being.
Modern brick facades mostly consist of homogeneous bricks. The Keller companies and HSLU researchers have developed a production process for bricks that opens up completely new design possibilities for architects. The joint Innosuisse research project arose from an award-winning thesis in the Master Design at HSLU.
Their task is to monitor the condition of ecosystems, for instance in the forest floor - and crumble to dust when their work is done: bio-gliders modeled on the Java cucumber, which sails its seeds dozens of meters through the air. researchers have developed these sustainable flying sensors from potato starch and wood waste.
Researchers have identified a new brain circuit in mouse embryos that develops at an unexpectedly early stage. Their findings may provide new insights into circuit abnormalities in autism. A research team led by Professor Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) and the University of Basel has studied circuits in the brains of living mouse embyros.
