A comprehensive inventory of Swiss glacial lakes shows how the lake landscape in the high mountains has changed since the end of the Little Ice Age. Due to climate change, the glaciers of the Alps are melting. When the sometimes huge ice fields retreat, they often leave behind depressions and natural dams in the exposed landscape.
An international research team of cryptographers completed a detailed security analysis of the popular Telegram messaging platform identifying several weaknesses in its protocol that demonstrate the product falls short of some essential data security guarantees. Working with only open-source code and without "attacking" any of Telegram's running systems, a small team of international researchers completed a detailed analysis of the company's encryption services.
The brain mechanisms underlying the suppression of fear responses have attracted a lot of attention as they are relevant for therapy of human anxiety disorders. Despite our broad understanding of the different brain regions activated during the experience of fear, how fear responses can be suppressed remains largely elusive.
SUMMER SERIES: HOW SCIENCE WORKS For scientists, the path from bright idea to finished product is a long one. Prototypes must go through an extensive testing and approval process before they are ready for the market. Let's have a look. The results of scientific research can often bring considerable societal and economic benefits.
Insulation webs are essential in aluminum window profiles and facades for good thermal insulation. researchers and their partners have been working for some time on a novel "sandwich" product with an environmentally friendly filling: recycled material from PET bottles. Now the market launch is approaching - with good prospects of success.
Open Science is an important development in science - open access to the results of research. Eawag supports these and makes a growing part of its research data, including descriptions, images and even software, available publicly and free of charge on the Eawag platform ERIC or, in special cases, on discipline-specific, international databases.

A team of scientists turned Bois-Chamblard park in Buchillon, on Lake Geneva, into a temporary research station for collecting experimental data. Their goal is to better understand how anthropogenic air pollution affects plant growth. What role does air pollution play in plant growth? That's the question a cross-disciplinary team of scientists has set out to answer.
Thanks to a unique system that decodes brain activity during sleep, a team from the University of Geneva is deciphering the neuronal mechanisms of memory consolidation. We sleep on average one third of our time. But what does the brain do during these long hours? Using an artificial intelligence approach capable of decoding brain activity during sleep, scientists at the University of Geneva , Switzerland, were able to glimpse what we think about when we are asleep.
Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. Based on this, one can study quantum effects in macroscopic objects and build extremely sensitive sensors. Why can atoms or elementary particles behave like waves according to quantum physics, which allows them to be in several places at the same time?
The Lausanne University Hospital (CHUV) and EPFL teamed up to develop a new test that's sensitive enough to measure the amount of SARS-CoV-2 neutralizing antibodies present in the bloodstream. The scientists' discovery, published in the prestigious Science Translational Medicine , opens promising new avenues for tracking immunity acquired by infection or vaccination.
When fluorescent dye molecules nestle perfectly together, something completely new is created: an excited state distributed over many molecules. Such collective excitations can be used in a variety of ways - for organic solar panels, in sensors, for ultrafast data transmission or in microscopy, for example.
An international team, led by UNIGE and MHN, has optimized a method for analyzing the genomes of specimens from natural history collections making possible to identify their placement along the evolutionary timeline. Museum specimens held in natural history collections around the world represent a wealth of underutilized genetic information due to the poor state of preservation of the DNA, which often makes it difficult to sequence.
Long considered 'junk', non-coding RNAs have emerged as important regulators of diverse cellular processes, including the silencing of genes. Working in yeast, researchers from the Bühler group have identified more than 20 mutations that enable RNA-mediated gene silencing. The findings could improve our understanding of the factors that keep gene silencing in check.
An international team of scientists led by EPFL has developed a system that combines information from the brain's connectome - the "wiring" between neurons - and machine learning to assess and predict the outcome of stroke victims. When blood flow to the brain is somehow reduced or restricted, a person can suffer what we know as a stroke (from "ischemic stroke" in medical jargon).
Based on observational data from Europe, climate researchers from ETH Zurich have shown for the first time that forests lead to a rise in precipitation. Their analyses also revealed that if the available agricultural land were reforested, the amount of precipitation in Europe could increase by more than 7 percent.
Researchers from the Prostate Cancer Biology laboratory, directed by Giuseppina Carbone, M.D., at the Institute of Oncology Research (IOR, affiliated to USI) in Bellinzona, have discovered an unexpected mechanism that drives the largest group of prostate tumors' evolution, the ERG fusion-positive prostate cancers.
Harnessing AI to discover new drugs inspired by nature
Artificial intelligence (AI) is able to recognise the biological activity of natural products in a targeted manner, as researchers at ETH Zurich have demonstrated. Moreover, AI helps to find molecules that have the same effect as a natural substance but are easier to manufacture. This opens up huge possibilities for drug discovery, which also have potential to rewrite the rulebook for pharmaceutical research.

Proteins known as transcription factors act as switches that regulate the expression of nearby genes, but the identity of some of these genetic levers has so far remained mysterious. Now, researchers from the Schübeler group have pinpointed a new switch that regulates essential genes in the mouse and the human genome.
Two UNIGE teams have discovered that the location of a specific chromosomal site is transmitted between two generations, even if the part of the protein that initially defines that site is absent in the offspring. Most biological traits are inherited through genes, but there are exceptions to this rule.
