An international research team led by Gino Caspari from the University of Bern has analyzed tattoos on a Siberian ice mummy that is over 2000 years old. For the study, the team used high-resolution near-infrared photography and collaborated with a contemporary tattoo artist. The results suggest that tattooing was a similar craft in prehistoric Siberian society as it is today.

An international research group involving the University of Bern has discovered that soil microorganisms shift their seasonal rhythm more than plants in response to climate warming. The resulting discrepancy between plants and microorganisms could disrupt essential ecosystem processes and jeopardize their functionality.

Researchers from the University of Bern, in collaboration with researchers from Australia and New Zealand, have recreated an important process in the laboratory that enables organisms to obtain energy directly from components found in air. This confirms that certain organisms such as bacteria can actually live on air alone, without relying on sunlight or other energy sources.

A new study led by researchers from the Institute of Virology and Immunology (IVI) and the University of Bern in collaboration with the Lausanne University Hospital and the Spiez Federal Laboratory shows that the monkeypox virus can spread efficiently in brain organoids, causing neuronal cell death.

Researchers from the University of Bern, Inselspital, Bern University Hospital and Charité - Universitätsmedizin Berlin have discovered that the composition of our diet in early life can strengthen the immune system. Using a mouse model, the researchers showed that certain food components increase the production and diversity of antibodies in the intestine, regardless of the existing intestinal microbiota.

A new study by researchers of the University of Bern shows that the hilly surface of Mercury could be influenced not only by the cooling and contraction of the planet, but also by the tidal forces of the Sun. Future analysis will draw on new data from the BepiColombo mission, which is currently on its way to Mercury.

The US research center for particle physics "Fermilab" recently published the results of a groundbreaking experiment with muons - particles that play a central role in the so-called standard model of particle physics - for the third time. At the same time, a new study on complex theoretical calculations of the so-called magnetic dipole moment of the muon was published under the leadership of researchers from the University of Bern.

In a recent study, researchers from the University Gynecology Clinic at the Inselspital, the University Hospital of Berne and the University of Berne investigated whether continuous real-time blood glucose measurement using a sensor could be used as an alternative to conventional finger-prick blood glucose measurement in patients with gestational diabetes.

A new study led by the University of Bern and Brown University in the U.S. casts doubt on one of the most tantalizing clues that water might be flowing on present-day Mars. Researchers analyzed a global database of 500,000 enigmatic streaks that occur on steep Martian slopes, concluding that they're most likely caused by dry processes rather than liquid flow.

Several tectonic processes are occurring beneath the surface of Venus, according to a new study led by researchers from the University of Bern's Center for Space and Habitability (CSH) and NASA. They found that many of the numerous "coronae" scattered all'over Venus' globe are associated with gravity field perturbations, hinting at the sub-surface tectonic processes.

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.
