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.

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.

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.

Agriculture began in the Amazon 10'000 years ago

As a new study shows, more than 10,000 years ago, people in the southwest of the Amazon began growing manioc and squash, 8,000 years earlier than previously thought. The area is thus one of the early Holocene centres of plant domestication in the world. People also changed the landscape by creating thousands of so-called forest islands.

About the distribution of biodiversity on our planet

Large open-water fish predators such as tunas or sharks hunt for prey more intensively in the temperate zone than near the equator. With this result, a study headed by Marius Roesti of the University of Bern is challenging a long-standing explanation for the distribution of biodiversity on our planet.

CHEOPS first check-up

Questioning theory can be worth it

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

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).

CHEOPS is now being tested for precision and the first images are being produced. CHEOPS is a joint mission of ESA and Switzerland, led by the University of Bern, in collaboration with the University of Geneva.

The salt of the comet

Under the leadership of astrophysicist Kathrin Altwegg, Bernese researchers have found an explanation for why very little nitrogen could previously be accounted for in the nebulous covering of comets: the building block for life predominantly occurs in the form of ammonium salts, the occurrence of which could not previously be measured. The salts may be a further indication that comet impacts may have made life on Earth possible in the first place.

Interstellar journey of life’s building block phosphorus unveiled

Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it became available on the early Earth when life appeared here about 4 billion years ago is something of a mystery. For the first time, astronomers – among them researchers from the University of Bern – have now been able to show that molecules with phosphorus are formed in star-forming regions and probably came to Earth with comets.

CHEOPS Launch alert!

Summer school takes science diplomacy to new level

When two researchers – one Israeli, the other Palestinian - met at a conference, they bonded over a mutual interest in a parasite and realized that science can indeed cross borders. This ethos is at the heart of the summer school they went on to found, the Middle Eastern Biology of Parasitism (MeBoP), which is hosted by the University of Bern.
