Special operation

Due to the current situation, the Dean's Office has reduced counter service until further notice.

One-year launch anniversary of CHEOPS

In its first year in orbit, the CHEOPS space telescope has already revealed details of one of the most extreme exoplanets and showed its maneuverability by evading space debris. 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.

A pair of lonely planet-like objects born like stars

An international research team led by the University of Bern has discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.

EU-funded research grants for two researchers from Bern

Two researchers from the University of Bern will receive an ERC Consolidator Grant this year. The coveted European Research Council (ERC) grants go to physicist Akitaka Ariga and geographer Chinwe Ifejika Speranza.

The Swiss Alps continue to rise

An international team of geologists, headed by members of the University of Bern, has shown for the first time that the Swiss Alps are being lifted faster than they are being lowered through erosion – and are thus growing even higher. To do this, the researchers quantified the erosion of the Alps with the help of isotopes measured in the sand of more than 350 rivers throughout the European Alps. These isotopes are formed by cosmic rays and bear information on the Earth’s surface erosion.

Bernese Researchers on Highly Cited Researchers 2020 List

Researchers at the University of Bern are among the most cited scientists in the world. The annual list of Highly Cited Researchers includes researchers whose work ranks in the top 1% of cited scientific publications in their respective fields. In 2020, researchers from Bern from various fields such as medicine, epidemiology, biology, environment/ ecology or Cross-Field have been recognized on the list.

Land management in forest and grasslands: how much can we intensify?

High land-use intensity reduces the beneficial effects of biodiversity on ecosystem services. This is the main result of a study conducted by an international team with participation of the University of Bern. The study assessed, for the first time, the effects of land management on the links between biodiversity, ecosystem functions and ecosystem services. It identified thresholds of management intensity, where these relationships change dramatically, which species groups were most important in driving services, and the ecosystem services that are at risk when management is intensified.

Two planets around a red dwarf

The “SAINT-EX” Observatory, led by scientists from the National Centre of Competence in Research NCCR PlanetS of the University of Bern and the University of Geneva, has detected two exoplanets orbiting the star TOI-1266. The Mexico-based telescope thus demonstrates its high precision and takes an important step in the quest of finding potentially habitable worlds.

Venus flyby on the way to Mercury

The space probe BepiColombo, which is on its way to Mercury, will fly past Venus on October 15, 2020 – one of the deceleration maneuvers to bring the probe into orbit in front of Mercury. BepiColombo has instruments on board which were designed and built at the Physics Institute of the University of Bern. Data is now being collected on Venus on the way to Mercury using other instruments that the Bern researchers are involved in.

First study with CHEOPS data describes one of the most extreme planets in the universe

CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b – one of the most extreme planets known. 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.

Marine heatwaves are human made

Heatwaves in the world’s oceans have become over 20 times more frequent due to human influence. This is what researchers from the Oeschger Centre for Climate Research at the University of Bern are now able to prove. Marine heatwaves destroy ecosystems and damage fisheries.

Comet Chury's ultraviolet aurora

On Earth, auroras, also called northern lights, have always fascinated people. An international consortium involving the University of Bern has now discovered such auroras in the ultraviolet wavelength range at comet 67P/Churyumov-Gerasimenko, Chury for short. This phenomenon was detected thanks to the analysis of data from the European Space Agency ESA's Rosetta mission.

Nationwide decline of threatened plant species in Switzerland

The Swiss Flora is one of the richest and most diverse in Europe. However, more than 700 plant species are considered to be threatened. In a nationwide project over 400 volunteer botanists revisited known populations of all threatened and rare plant species in Switzerland and recorded their presence or absence. Researchers from the University of Bern and the National Data and Information Center on the Swiss Flora have now analysed the dataset, and the results are alarming.

Four ERC Starting Grants for researchers from Bern

Four researchers from the University of Bern will receive the coveted Starting Grants from the European Research Council (ERC). Plant researcher Christelle Robert wants to use the grant to understand the interactions between plants and the natural enemies of pests, while economist Christoph Oberlack is investigating new ways of establishing environmental justice. Physiopathologist Ziad Al Nabhani is investigating the influence of early childhood nutrition on the immune system, and chemist Tomás Solomek is exploring new ways to better understand and use a material of the future.

Space debris observed for the first time during the day

Researchers at the University of Bern are the first in the world to succeed in determining the distance to a space debris object using a geodetic laser in daylight. The distance was determined on June 24, 2020 at the Swiss Optical Ground Station and Geodynamics Observatory Zimmerwald. The number of measurements can be multiplied thanks to the new possibility of observing space debris during the day. As a result, possible collisions with satellites can be detected at an early stage and evasive maneuvers can be initiated.

Explosive diversification explained by network analysis

Using genomic analyses of 100 cichlid species, scientists from Eawag and the University Bern, together with co-workers in Australia, the UK, Tanzania, Uganda and the US, have investigated the striking variation observed in cichlid fish speciation rates. Their findings show that exchanges of genetic variants between existing species dramatically accelerate the development of new species – given favourable ecological conditions.

Fuel cells for hydrogen vehicles are becoming longer lasting

An international research team led by the University of Bern has succeeded in developing an electrocatalyst for hydrogen fuel cells which, in contrast to the catalysts commonly used today, does not require a carbon carrier and is therefore much more stable. The new process is industrially applicable and can be used to further optimize fuel cell powered vehicles without CO₂ emissions.

Anthropogenic CO₂ increase is unprecedented

Even in earlier warm periods there were pulse-like releases of CO₂ to the atmosphere. Today's anthropogenic CO₂ rise, however, is more than six times larger and almost ten times faster than previous jumps in the CO₂ concentration. This is the conclusion reached by a European research team led by the University of Bern.

The most sensitive instrument in the search for life in space comes from Bern

Researchers at the University of Bern have developed the highly sensitive ORIGIN instrument, which can provide proof of the smallest amounts of traces of life, for future space missions. Space agencies such as NASA have already expressed interest in testing ORIGIN for future missions. The instrument may be used on missions to the ice moons of Europa (Jupiter) and Enceladus (Saturn), for example.
