Researchers at the University of Bern, together with scientists from Stanford University and the European Molecular Biology Laboratory (EMBL), have discovered a new cellular mechanism that controls the stability of messenger RNA (mRNA) in cells. When this mechanism is disrupted, tumors can grow more quickly.

Researchers from the University of Bern, Inselspital, Bern University Hospital, and ETH Zurich have developed an innovative technology which can clean implanted medical devices such as ureteral stents and catheters non-invasively, using ultrasound activation through the skin. This could significantly improve the quality of life of patients and at the same time reduce the financial burden on the healthcare system.

A team from the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS has developed a machine learning model that predicts potential planetary systems with Earth-like planets. The model could significantly accelerate and thus revolutionize the future search for habitable planets in the universe.

Researchers at the Inselspital, Bern University Hospital and the University of Bern have developed an AI-based tool that detects and classifies abnormalities of the coronary arteries in CT images with high precision. This could significantly improve the diagnosis and treatment of rare heart diseases.

Researchers at the University of Bern have analyzed a mechanism by which the coronavirus manipulates human cells to replicate itself. They show that a coronavirus protein, which is central to infection, has two independent functions. Only one function however occurs in several species of coronaviruses.

Atrial fibrillation is the most common cardiac arrhythmia worldwide. While exist-ing interventional treatment methods, such as catheter ablation, work better than medication, they still have their limitations and risks.

Researchers from the University of Bern and the RIKEN research institute in Japan have made a significant advance in sustainable chemistry. They have succeeded in producing organic molecules through a chemical reaction based on the sustainable metals sodium and iron. This represents a more environmentally friendly alternative to conventional methods and has the potential to fundamentally change the production of pharmaceuticals and other fine chemicals.

A new special volume, initiated and edited by researchers from the University of Bern, examines the biological roots of the division of labor - from microorganisms to humans.

Gastrointestinal inflammation can cause long-term gastrointestinal disorders. An international research team led by the Charité - Universitätsmedizin Berlin, the Inselspital, Bern University Hospital, and the University of Bern has shown for the first time that inflammation damages nerve cells in the intestine.

Two years ago, global sea surface temperatures rose sharply, considerably exceeding previous highs. A study by the University of Bern shows that such extreme temperature jumps would not be possible without the influence of climate change. The study also confirms that climate models simulate such events realistically.

Extreme weather and climate events such as droughts and floods in Europe can be linked to shifts in the jet stream over the Atlantic.

An international research team led by the University of Bern and Brown University in the US state of Rhode Island may have solved the mystery of the reddish color of Mars. The team identified the water-rich iron mineral ferrihydrite as the main culprit of the characteristic reddish Martian dust. This discovery could not only explain the planet's color, but also point to a wetter, potentially habitable Martian past.

Researchers from the University of Bern, in collaboration with the University of Science and Technology Houari Boumediene in Algeria, have made significant progress in astrobiology. In a recently published study, they were able to detect fossil microorganisms in Messinian gypsum, which is found in Algeria, using the Bernese mass spectrometer LIMS.

Meteoroid impacts create seismic waves that cause Mars to shake stronger and deeper than previously thought: This is shown by an investigation using artificial intelligence carried out by an international research team led by the University of Bern. Similarities were found between numerous meteoroid impacts on the surface of Mars and marsquakes recorded by NASA's Mars lander InSight.

Around one in ten diagnoses is wrong. In an extensive study, a research team led by Inselspital, Bern University Hospital, and the University of Bern has investigated whether an AI-based diagnostic system could improve diagnostic quality. The result is surprising: despite high expectations, the system that was tested showed no measurable advantage over conventional diagnostic processes.

A study by the University of Bern and the Woods Hole Oceanographic Institution in the USA concludes that ocean circulation in the North Atlantic, which includes the Gulf Stream, has not weakened over the past 60 years. These results contradict previous assumptions. We owe the mild climate in Europe to the ocean circulation in the North Atlantic, which not only transports heat northwards from the equator, but also distributes oxygen and nutrients in the ocean.

The search for the world's oldest ice in Antarctica is entering a decisive phase. In this major European project, researchers in Antarctica are attempting to extract drill cores containing climate information from the past 1.5 million years. The University of Bern is playing an important role in this.

Rats release trapped companions, subsequently enabling them to collaborate for acquiring food. Experiments conducted at the University of Bern established this connection between obliging liberation behaviour and coordinated cooperation. These results may point towards a biological basis for empathy, presenting new perspectives on the evolutionary origins of compassionate behaviour.

An international team of researchers involving the University of Bern has investigated the consequences of deforestation and degradation of tropical forests. They were able to show that there are "winner" and "loser" species, whereby the displacement of the "losers" can lead to a decline in the ecological functions of tropical forests.

An interdisciplinary study from the University of Bern reveals that gut bacteria play a crucial role in converting arsenobetaine into toxic arsenic compounds. Results show that arsenobetaine, commonly found in seafood and previously considered harmless, is partly transformed into toxic arsenic compounds by the action of gut bacteria in the mammalian body.
