Researchers are using machine learning to map nitrate pollution in Swiss groundwater. This allows gaps in the measurement network to be filled and the causes of excessive values to be identified. The study is part of a larger project analysing the nitrogen cycle in Switzerland. Nitrate levels in groundwater exceed the limit of 25 milligrams per litre at 15 percent of all measuring points in Switzerland.

Researchers from Empa, EPFL and CSEM have developed a green smart sensing tag that measures temperature and humidity in real time - and can also detect whether a temperature threshold has been exceeded. In future, this could be used to monitor sensitive shipments such as medicines or food. The sensor tag itself is completely biodegradable.

This indicator would enable us to quickly identify elderly people at risk of frequent emergency room visits and death The number of medications taken by the elderly is constantly on the rise, and we

McGill-led research using the James Webb Space Telescope sheds new light on how planetary atmospheres evolve Using the James Webb Space Telescope (JWST), a team led by McGill researcher Vigneshwaran Krishnamurthy has observed a giant cloud of helium gas evaporating from a distant giant exoplanet called WASP-107b.

Using images from the James Webb Space Telescope (Webb), an international research team including Western's Stanimir Metchev has discovered new answers to explain how some brown dwarfs form giant dust storms, contradicting previous assumptions. These storms may look similar to Jupiter's iconic Great Red Spot, but the new study, led by Shanghai Jiao Tong University, shows they actually form quite differently.

Researchers from EPFL, Empa, and CSEM have developed a sustainable smart sensing tag that can be used to signal when shipments of medicines or food have exceeded a safe threshold temperature.

Researchers at Universidad Carlos III de Madrid (UC3M) have developed a set of innovative methods and algorithms that improve the performance and precision of vehicle design through topological optimization, a mathematical technique that allows designs to be optimized by distributing materials efficiently.

A new study describes a key molecular mechanism that explains how cells exchange information through extracellular vesicles (EVs), small particles with great therapeutic potential. The results, published in the Journal of Extracellular Vesicles , reveal that the Commander protein complex, previously known for its role in membrane recycling, also coordinates the entry and internal destination of vesicles within the cell.

Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body's ways of stopping viruses in their tracks, according to new research led by the universities of Cambridge and Glasgow. Understanding what makes bird flu viruses cause serious illness in humans is crucial for surveillance and pandemic preparedness efforts Sam Wilson In a study , the team identified a gene that plays an important role in setting the temperature sensitivity of a virus.

Study demonstrates for the first time the effectiveness of adjunctive digital training during inpatient treatment A brief smartphone-based training programme completed by patients with depression alongside their inpatient treatment can lead to long-term reduction in depressive symptoms. This is the finding of a study conducted by psychologists at the University of Münster.

As many as one in six teenagers have self-harmed at some point in their lives. As well as being an indicator of emotional pain, self-harm is also the best-known predictor of death by suicide - yet researchers know little about the emotional and biological factors that lead to it. A new study published in Nature Mental Health, led by Professor Rory O'Connor from the University of Glasgow and funded by the Medical Research Foundation, helps to uncover the biological mechanisms behind why young people self-harm.

A new look at sleep monitoring Two researchers from Eindhoven University of Technology and their team develop new ways to monitor sleep disorders. Sebastiaan Overeem and Merel van Gilst don't necessarily want more accuracy when gathering sleep data from patients with sleeping disorders. Instead, they want more room for uncertainty and ways to show that.

When you tattoo your skin, you also "tattoo" your immune system. This is the finding of an innovative study conducted by the Infection and Immunity group at the Institute for Research in Biomedicine (IRB), affiliated with Università della Svizzera italiana (USI), led by Prof. Santiago F. González and published today in Proceedings of the National Academy of Sciences (PNAS).

Low blood sugar (hypoglycemia) is a critical diabetes-related condition. Researchers at the Inselspital, Bern University Hospital and the University of Bern have now shown for the first time that the human voice can even reveal early signs of hypoglycemia. Recordings made with the microphone of an ordinary smartphone and analyzed using artificial intelligence could make diabetes management safer and easier in the future.

To ensure their survival in a new environment, insects must be able to change their eating habits depending on the food supply. In collaboration with experts from Switzerland, Portugal and Germany, researchers at the University of Fribourg were able to show that this ability to adapt is also controlled by mechanisms in the brain.

A new combination of data and statistical algorithms makes it possible for the first time to precisely track the movements of animals deep underwater. An initial study of flapper skate on the seabed around Scotland will help to develop targeted measures to conserve these Critically Endangered animals and designate suitable protected areas.

Professor Lluís Gibert, from the University of Barcelona, is the only expert from a European institution participating in an international study based on the analysis of the bones of a fossilized foot and teeth that has revealed how Australopithecus deyiremeda , a human ancestor that coexisted more than three million years ago with Australopithecus afarensis - the famous Lucy - on the plains of East Africa, moved and fed.

Long-term exposure to toxic air can substantially weaken the health benefits of regular exercise, suggests a new study by an international team including UCL researchers. The study, published in the journal BMC Medicine , analysed data from more than 1.5 million adults tracked for more than a decade in countries including the UK, Taiwan, China, Denmark and the United States.

Glossy flowers are visible to bees from a distance, but make color recognition difficult up close. They thus represent a visual compromise of nature, as a new study by the University of Würzburg shows. The existence of glossy surfaces in the plant and animal world poses a mystery to science. This is because clear and consistent signals are advantageous for reliable communication, for example between flowers and pollinators.

Posted on: 26 November 2025 The scientists have discovered that a single inherited mutation causes whole-body issues in a model of inherited primary mitochondrial disorders after the immune response is sparked into action. Although the scientists stress the research is at a relatively early stage, it is one of the first pieces of work to show that a heritable mitochondrial DNA mutation can independently remodel immune cell function and inflammatory signalling.
