A team of researchers from the Institute for Infectious Diseases (IFIK) at the University of Bern and the Institute of Virology and Immunology (IVI) have used a unique collection of advanced cell culture models of cells lining the airways from various domesticated and wildlife animals to determine which animals are susceptibly to SARS-CoV-2 infection.

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.

While studying two exoplanets in a bright nearby star system, the CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet -with no known equivalent-, as the scientific team led by the Universities of Geneva and Bern, and members of the National Center of Competence in Research PlanetS, point out.

It could be a milestone on the path to detecting life on other planets: Scientists under the leadership of the University of Bern and of the National Centre of Competence in Research (NCCR) PlanetS detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground.

A study conducted at the Oeschger Centre for Climate Change Research at the University of Bern provides new insights into the pollution of the world's oceans with plastic waste. The modelling shows that most of the plastic does not end up in the open ocean, but beaches or drifts in the water near the coast.

The Southern Ocean dominates the oceanic uptake of human-made CO2. But how much carbon dioxide can it actually absorb in the future? This long-standing question remained unresolved as projections of different generation of climate models repeatedly showed a wide range of future Southern Ocean CO2 sink estimates.

Researchers from the Oeschger Centre for Climate Change Research at the University of Bern reconstructed for the first mean ocean temperatures over the last 700,000 years using ice core data. The new knowledge serves to improve our understanding of the climate system. Bern's ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years.

For a long time, climate researchers could not explain the high concentration of greenhouse gases in the Earth's atmosphere around three billion years ago. Now an international research team with the participation of Hendrik Vogel from the Institute of Geological Sciences and Oeschger Centre for Climate Change Research at the University of Bern has solved the mystery.

The US research laboratory "Fermilab" has published the eagerly awaited results of the experimental measurement of the so-called anomalous magnetic dipole moment of the muon. As members of the "Muon g-2 Theory Initiative", researchers from the University of Bern have calculated the same physical quantity theoretically in parallel, based on the Standard Model.

Although past temperature variations in the tropics are of great importance to understanding the global climate system, little is known about their extent and chronological course. Researchers under the leadership of the University of Bern have now been able to demonstrate strong local cooling in the tropics during the last glacial period on the basis of glacier fluctuations and large stone stripes in the Ethiopian Highlands.

The weathering of silicate rocks plays an important role to keep the climate on Earth clement. Scientists led by the University of Bern and the Swiss national center of competence in research (NCCR) PlanetS, investigated the general principles of this process. Their results could influence how we interpret the signals from distant worlds - including such that may hint towards life.

Scientists at Urology Research Laboratory of the Department for BioMedical Research (DBMR), University of Bern and Urology Department of the Inselspital of Bern, have established organoid culture models from prostate tumor biopsies. These are small clusters of cells which can be used to test the efficacy of various drugs.

Adhesions are scars in the abdomen, which can occur after surgery, often have serious consequences. Now, researchers from the University of Bern and Inselspital, University Hospital Bern, in collaboration with Canadian researchers, have discovered how such adhesions form. The findings may help to develop a drug to prevent adhesions in the future.

Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Under the leadership of the University of Bern and the National Center of Competence in Research NCCR PlanetS, scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet.

How dangerous are new mutations of the SARS-CoV-2 virus? An international team involving researchers from the Institute of Virology and Immunology (IVI) of the Federal Food Safety and Veterinary Office BLV and the University of Bern (Switzerland), the Centers for Disease Control and Prevention (USA), and the Friedrich-Loeffler Institute (Germany), has developed an approach that can accurately assess the transmissibility of new virus mutants.

Cancer research has discovered a further mechanism to combat leukemia: a research team has succeeded in identifying an important signaling pathway for regulating leukemic stem cells. With this discovery, the researchers are expanding the arsenal of potentially highly effective drugs against leukemias ("blood cancers").

In collaboration with clinical partners from the Inselspital, researchers from the ARTORG Center for Biomedical Research of the University of Bern have developed a second-generation lung-on-chip model with life-size dimension alveoli in a stretchable membrane, made of purely biological material. The new model reproduces key aspects of the lung tissue architecture not found in previous lungs-on-chip.

Unlike their simple counterparts in artificial intelligence (AI) applications, neurons in the brain use dendrites - their intricate tree-like branches - to find relevant chunks of information. Now, neuroscientists from the University of Bern have discovered a new computational method to make complex dendrite models much simpler.

The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found outside our solar system. An international study involving researchers from the Universities of Bern, Geneva and Zurich now shows that the exoplanets have remarkably similar densities, which provides clues about their composition.

The nationwide study published today was initiated by Inselspital, Bern University Hospital with the collaboration of the University of Bern and has established for the first time: severe Covid-19 can result in prolonged impairment of oxygen uptake in the lungs even after four months. Long-term monitoring and treatment of these patients is urgent and important.
