Coronavirus: Returning home from trips abroad

People entering Switzerland from a country or an area with an increased risk of infection must go into quarantine for 10 days. This means: Go immediately to your home or other suitable accommodation after entry. You must stay there continuously for 10 days after your arrival. Within two days of your arrival, report your entry to the Canton of Bern. All necessary information can be found on the Corona website.

REM sleep tunes eating behaviour

Despite our broad understanding of the different brain regions activated during rapid-eye-movement sleep, little is known about what this activity serves for. Researchers at the University of Bern and the Inselspital have now discovered that the activation of neurons in the hypothalamus during REM sleep regulates eating behaviour: suppressing this activity in mice decreases appetite.

Gut microbes shape our antibodies before we are infected by pathogens

Colonization with intestinal microbes is known to shape many body systems, especially the white blood cells that produce antibodies. Because the microbiota is so complex, containing hundreds of different bacterial species, it is not known how the presence of microbes in the intestine shaped the antibodies that are present even before we are challenged by an infection. Researchers at the Department for BioMedical Research (DBMR) of the University of Bern and the Inselspital, University Hospital Bern, have now shown how these beneficial microbes reprogram the repertoire of white blood B cells that produce antibodies and how this helps counter infections.

Rapid test for the determination of antibodies against SARS-CoV-2

A Swiss-German team presents a test that determines the amount of neutralising antibodies within a short period of time. The test was developed at the Institute of Virology and Immunology (IVI) of the University of Bern and the Swiss Federal Office for Food Safety and Animal Health, and evaluated in cooperation with colleagues from the Ruhr-University Bochum using serum samples from COVID-19 patients.

Immunoprotein impairs Sars-Cov-2

An international team with researchers of the Institute of Virology and Immunology (IVI) of the University of Bern and the Swiss Federal Food Safety and Veterinary Office (FSVO) showed that an endogenous protein prevents the virus from fusing with host cells. This raises hopes for new therapeutic approaches.

Ethical recommendations for triage of COVID-19 patients

An international expert group led by Mathias Wirth, Professor of Systematic Theology and Ethics at the University of Bern, has developed recommendations for avoiding triage of COVID-19 patients in extreme situations. The recommendations should support medical personnel in difficult decisions during a second wave of the infection and ensure better patient care.

Age-related impairments reversed in animal model

Frailty and immune decline are two main features of old age. Researchers from the University of Bern and the University Hospital Bern now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therapeutic approach.

The planetary scientist has one great wish

Christoph Mordasini deals with the formation and evolution of planets inside and outside our solar system. In an interview he explains why the University of Bern has been at the forefront of space research since an experiment on the moon. And he reveals the question to which he would very much like to have an answer.

First exposed planetary core discovered

Researchers led by the University of Warwick have discovered the first exposed core of an exoplanet, which provides an unprecedented glimpse inside the interior of a planet. Christoph Mordasini from the University of Bern is leading the theoretical interpretation of this discovery.

swissuniversities and Springer Nature sign a new Open Access agreement

swissuniversities has adopted a new transformative Open Access agreement with Springer Nature. This agreement provides Swiss researchers with access to SpringerLink with over 2’000 Hybrid journals and enables authors affiliated with the Swiss academic and research institutions to publish their accepted research papers Open Access, making this primary research immediately and freely accessible from the point of publication.

Push for non-animal methods

No less than three research groups at the University of Bern receive funding from the Swiss 3R Competence Centre (3RCC) for innovative projects that aim to replace animal experiments. In order to study cancer, idiopathic pulmonary fibrosis and drug transfer between mother and fetus, human patient cells are cultivated in the laboratory.

Alarming long-term effects of insecticides weaken ant colonies

This week, scientists of the Institute of Bee Health of the University of Bern have published an article in the peer-reviewed journal Communications Biology, which shows how even low doses of neonicotinoid insecticides, as they may realistically occur in contaminated soils, adversely affect the development of black garden ants (Lasius niger). This study highlights the need to overthink current deployment and management of chemical pest control for more sustainable agriculture.

Arctic Ocean acidification worse than previously expected

The Arctic Ocean will take up more CO2 over the 21st century than predicted by most climate models. This additional CO2 causes a distinctly stronger ocean acidification. These results were published in a study by climate scientists from the University of Bern and École normale supérieure in Paris. Ocean acidification threatens the life of calcifying organisms – such as mussels and "sea butterflies" – and can have serious consequences for the entire food chain.

Deadly bacterial infection in pigs deciphered

New-born piglets often die painfully from infection with an intestinal bacterium. A team of researchers from 3 faculties at the University of Bern has now discovered how the bacterium causes fatal intestinal bleeding. They have thus made a breakthrough in veterinary research. Promising prospects for vaccinations and medications for use in humans too have now opened up.

Designing animal studies to improve research reproducibility and reduce animal use

At the invitation of the University of Bern, international experts worked out new recommendations for the design of animal studies. They encourage a paradigm shift to improve the reproducibility of scientific results and reduce animal numbers.

Even natural products can be harmful for the unborn child

Plant products ingested by pregnant women through their diet are broken down by the intestinal microbiota into chemical substances, some of which can cross the placental barrier and reach the fetus. These foreign substances can harm the unborn child, even if they are of "natural origin". Researchers at the Department for BioMedical Research (DBMR) at the University of Bern and Inselspital, University Hospital Bern, therefore warn against underestimating the effects of such substances.

Dynamic measures against the coronavirus examined

An alternating cycle of suppression interventions and relaxation could offer a pragmatic strategy - particularly for developing countries - to prevent health systems from being overloaded while reducing the economical and societal burden. This is illustrated in an international study with significant participation by the Institute for Social and Preventive Medicine (ISPM) at the University of Bern.

2019 digital annual report: Knowledge that shapes the future

The University of Bern’s 2019 annual report has now been published in digital format for the first time. The past year was shaped by many major accomplishments such as the launch of the CHEOPS mission, the founding of the Wyss Academy for Nature and the grand opening of the sitem-insel translational center. More than 18,500 students attended the University of Bern for the first time.

Geography of childhood cancer in Switzerland studied

A research group under the direction of the Institute of Social and Preventive Medicine of the University Bern has investigated the spatial distribution of childhood cancer risks in Switzerland for the period 1985-2015. The group found evidence of increased risks in certain areas, particularly for brain tumors. The researchers demand that the search for the causes of brain tumors in children be intensified.

A major step towards the explanation of the matter-antimatter asymmetry

The international T2K Collaboration has published results showing the strongest evidence to date implying the breaking of the symmetry between matter and antimatter in so-called neutrino oscillations. This is a major step towards the understanding of the dominance of matter over antimatter in the Universe. A team of particle physicists from the University of Bern provided important contributions to the experiment.

CHEOPS space telescope ready for scientific operation

CHEOPS has reached its next milestone: Following extensive tests in Earth's orbit, some of which the mission team was forced to carry out from home due to the coronavirus crisis, the space telescope has been declared ready for science. CHEOPS stands for “CHaracterising ExOPlanet Satellite”, and has the purpose of investigating known exoplanets to determine, among other things, whether they have conditions that are hospitable to life.

Six Marie Skłodowska-Curie fellows are coming to the University of Bern

The University of Bern is welcoming six Marie Skłodowska-Curie fellows this year. The "Marie Skłodowska-Curie Individual Fellowships", awarded annually by the European Commission, give experienced researchers the opportunity to enrich their scientific careers with a stay abroad.

A new approach to improve biological control agents of agricultural pests

In a new study, researchers from the University of Bern developed an experimental approach that may be used to improve a wide range of organisms that rely on microbial symbionts to control insect pests. This approach opens up a new avenue for the improvement of biological control strategies towards a more sustainable, pesticide-free agriculture.

How wallflowers evolved a complementary pair of plant defenses

A new study led by Tobias Züst from the Institute of Plant Sciences of the University of Bern shows that a pair of complementary chemical defenses evolved independently in wallflowers, shaped by co-evolution with local insects.

Questioning theory can be worth it

Where few thought to look, the NCCR PlanetS co-funded telescope "SAINT-EX" is searching for new worlds. After a year of operation, the project has brought some exciting first results.

Puzzle about nitrogen solved thanks to cometary analogues

One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogues for comet material. The method on which the study on the detection of ammonium salt is based was developed at the University of Bern.

Tracking down the mystery of matter

Researchers from the University of Bern, PSI, and ETH Zurich, together with international partners, have demonstrated in an elaborate experiment at PSI that the electric dipole moment of the neutron is significantly smaller than previously assumed. It has thus become less likely that the existence of matter in the universe can be explained by this dipole moment.

Investments by the super-rich drive deforestation

Wealthy individuals are increasingly investing in agriculture. Their investments boost production of plant-based raw materials for human consumption, industrial uses, and animal fodder. The resulting capital flows directly contribute to deforestation in the global South, especially in the tropics. That is the conclusion of a new study by the University of Bern’s Centre for Development and Environment (CDE).

Bern and Fribourg researchers identify neurons responsible for rapid eye movements (REM) during sleep

Why do we move our eyes fast in the paradoxical sleep - in that sleep phase, in which most dreams take place? The secret is not yet fully aired, but we are on his track: A team at the University of Bern, in collaboration with the University of Fribourg, has identified the nerve cells behind this curious phenomenon.

Dr. Josef Steiner Cancer Research Award 2019 goes to a bioinformatician

The Dr. Josef Steiner Cancer Research Award for 2019, endowed with €900,000 and originally referred to as the "Nobel Prize for Cancer Research", is going to Prof. Serena Nik-Zainal of the University of Cambridge. Thanks to her research, mutations in cancerous tumors can be analyzed using new bioinformatic methods, which makes new targeted therapy approaches possible. The prize is being awarded today at the University of Bern.
