Ocean temperature reconstructed over the last 700,000 years
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.
How microbes influenced the Earth's atmosphere three billion years ago
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. Sediment analyses revealed the surprising result that under the conditions at that time, microbes mainly produced the highly effective greenhouse gas methane for their metabolism.
Why SARS-CoV-2 replicates better in the upper respiratory tract
A team of researchers from the Institute for Infectious Diseases (IFIK) at the University of Bern and the Federal Institute of Virology and Immunology (IVI) have assessed virus growth and activation of the cellular defense mechanisms in the respiratory tract. They have shown that natural temperature differences that exist in the upper and lower respiratory tract have a profound influence on SARS-CoV-2 replication and subsequent innate immune activation in human cells. The findings can help to develop antiviral drugs and preventive measures.

Glaciers and enigmatic stone stripes in the Ethiopian Highlands
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.
How the habitability of exoplanets is influenced by their rocks
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.
Predicting success in therapy with individualized cancer models
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. In this way, it is possible to test which treatment will most likely benefit individual patients.
Controlling adhesions in the abdomen
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. The study was published as the cover story of Science magazine.
Volcanoes might light up the night sky of this planet
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 to track the variants of the pandemic faster
A global group of researchers is calling for better integration of viral genetics, bioinformatics, and public health to enable better pandemic response now and better pandemic preparedness in the future. In a comment piece in the journal Nature, an international collaboration of specialists in viral and genetic analysis, led by Swiss scientists Dr. Emma Hodcroft at the University of Bern and Prof. Christophe Dessimoz at University of Lausanne, both at the SIB Swiss institute of Bioinformatics, alongside Dr. Nick Goldman at EMBL-EBI in the UK, lay out the ‘bioinformatics bottlenecks’ that are hindering response to the SARS-CoV-2 pandemic, and propose ways to ‘clear the road’ for better tools and approaches. Here are the key take home messages and perspective from the Swiss angle.
SARS-CoV-2 mutations in competition
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.
Targeted elimination of leukemic stem cells
Cancer research in Bern has discovered a further mechanism to combat leukemia: a research team at Inselspital, Bern University Hospital and the University of Bern 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”).
Bernese researchers create sophisticated lung-on-chip
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. This opens up new possibilities for basic pneumological research, understanding lung pathologies, drug screening and precision medicine.
Only 14% of the Bernese population have antibodies against coronavirus
In the canton of Bern, only 14% of the adult population were infected with the coronavirus and developed antibodies against SARS-Cov-2. These are the preliminary results of a seroprevalence study coordinated by the Swiss School of Public Health and carried out in Bern by the University of Bern in cooperation with the Inselspital, University Hospital of Bern.
Four Bernese researchers receive Pfizer Prize
This year, four of a total of fifteen Pfizer Research Prizes have been awarded to physicians from the University of Bern and the Inselspital, University Hospital Bern. The award-winning work deals with leukemia, cardiac arrhythmias and the fever threshold in children and adolescents with cancer.
A NEAT reduction of complex neuronal models accelerates brain research
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. These faithful reductions may lead AI applications to process information much like the brain does.
CHEOPS finds unique planetary system
The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are in a harmonic rhythm despite very different compositions – a novelty. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva.
TRAPPIST-1's 7 Rocky Planets May Be Made of Similar Stuff
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.
