Researchers have developed an extraordinary protection against corrosion after a chance discovery. It glows in places where it is not damaged, repairs itself - and can be reused multiple times. Skyscrapers, bridges, ships, aeroplanes, cars - everything humans make or build sooner or later decays. The ravages of time are known as corrosion; nothing is safe from it.
Modeling liver and kidney disease
In two separate studies, researchers at EPFL have carried out extensive tests to develop the best mouse models for studying kidney and liver diseases. The findings provide crucial insights into both conditions, and are expected to open up new avenues of research and treatment. "In these two studies we investigated how the mouse's genetic background affects the susceptibility to fatty liver disease and the transition from acute kidney injury to chronic kidney disease," says Professor Johan Auwerx at EPFL.

Researchers have studied residues from the incineration of graphene-containing plastics. Conclusion of the study: Burned composite materials containing graphene nanoparticles can be considered harmless in case of acute exposure. Due to its exceptional properties, graphene is now added to a wide range of plastics.
Many regions have suffered from heatwaves in recent years. But exactly how these form is still a matter of debate. Two researchers at ETH Zurich have now found a nuanced answer. Unusually hot weather in India and Pakistan at the end of March; a long, warmer-than-average summer in central Europe; extreme December temperatures in northern Argentina, Uruguay and Paraguay: 2022 was definitely a year of heat waves.
Scientists at the Paul Scherrer Institute PSI have used the Swiss X-ray free-electron laser SwissFEL and the Swiss Light Source SLS to make a film that could give a decisive boost to developing a new type of drug. They made the advance in the field of so-called photopharmacology, a discipline that develops active substances which can be specifically activated or deactivated with the help of light.
Researchers at EPFL have found that infection with a common bacterium that is linked to periodontal disease, oral cancers, and bad breath may cause a small increase in the risk of cardiovascular disease. A combination of genetic and environmental risk factors contributes to heart disease, which is responsible for about a third of all deaths worldwide.
Researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond. Until now, the ability to make electronic devices faster has come down to a simple principle: scaling down transistors and other components.
Up to now, the use of models to research the barrier that separates the circulatory from the nervous system has proven to be either limited or extremely complicated. Researchers at ETH Zurich have developed a more realistic model that can also be used to better explore new treatments for brain tumours.
The European Patent Office has granted Agroscope a patent for its new cheese maturing process. This patent was published - and thus became effective - on January 25, 2023 in the European Patent Bulletin. It will now be registered in some countries. In 2020, Agroscope applied for a patent for its new maturing process, which works as follows: after leaving the salt bath, the cheeses are wrapped in a biodegradable cloth.
By analysing sediments dating back to the global warming that happened 56 million years ago, a team from the University of Geneva is taking a new look at our climate future. 56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming.
Putting decentralised water treatment technologies into practice is not always easy. It often takes many small steps to motivate people to use these technologies. In a recent article, two environmental health psychologists from Eawag summarise in a "Theory of Change" what is known so far about the psychological factors influencing the use of decentralised water treatment technologies and the measures that could promote their adoption.
Architects at EPFL have developed a new, multi-criteria evaluation method to support better decision-making for the redevelopment of brownfield sites in Geneva, Sion and elsewhere along the Rhone.
After four years of research, EPFL's Blue Brain Project shares an enriched version of their 3D digital cell atlas of the mouse brain which includes more neuron types. The new approach can be extended to any other cell type, and provides a resource to build tissue-level models of the mouse brain.
A team of researchers reveals that the distribution of planets can be organised in four different ways around a star. Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers from the Universities of Bern and Geneva, as well as from the National Centre of Competence in Research PlanetS, have now shown for the first time that there are in fact four types of planetary systems.
Treating post-traumatic stress disorder with EMDR has been proven to be effective, but the mechanisms behind this therapeutic technique remain poorly understood. Three researchers from the University of Freiburg suspect that working memory plays a crucial role . A person who has been assaulted is at high risk of experiencing psychological trauma.
Tossing coins to understand spheres
EPFL mathematicians, in collaboration with Purdue University, have settled a 30-year-old question about spheres and 4-dimensional spaces. The results bring new light to the "Euler Class," one of the most powerful tools to understand complicated spaces. For mathematicians, "Euler Class" is one of the most powerful tools for understanding complicated spaces by cutting them into simpler pieces.

In a new approach to security that unites technology and art, researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages. Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL's School of Engineering.
Researchers have uncovered the intricacies of gene expression rhythms in humans, shedding new light on how sex and age influence our body clocks. The human body runs on a finely tuned clock synchronized to the 24-hour cycle of Earth's rotation, known as the circadian clock, which controls various physiological processes such as the sleep-wake cycle, hormone production, and metabolism.
In the cell, messenger RNAs — or mRNAs — are translated into proteins and eventually degraded, but the relationship between translation and mRNA decay remains cloudy. FMI researchers developed an innovative tool to control and visualize mRNA translation and decay, one molecule at the time.
A study by Swiss TPH and partners found that the COVID-19 pandemic has led to an increase in mental health concerns among mothers in Zambia. The study highlights the need for public health interventions for vulnerable groups in low-resource settings. The findings were recently published in the peer-reviewed journal PLOS One.
