Hans Sigrist Symposium 2019: Fascinating Exoplanet Science
The Hans Sigrist Symposium, which is taking place on Friday, December 6, 2019, is to address the topic of exoplanet research – and will therefore revolve around the question of whether Earth-like planets orbit other suns in the universe. The occasion coincides with the presentation of the prestigious Prize of the Hans Sigrist Foundation, which is based at the University of Bern, to the Dutch Astronomer, Prof. Dr. Ignas Snellen. The keynote speech by Ignas Snellen is entitled "The Search for Extraterrestrial Life".
A new pathway to "reprogram" killer cells
Killer cells of the immune system detect and kill infected cells or cancer cells. Researchers at the Institute of Pathology at the University of Bern have now discovered that the mechanism by which certain immune cells kill their target cells can also be used to control the killer cells themselves. This finding may be relevant to cancer immunotherapy.
Media conference “Launch of the CHEOPS mission”
For the time being, the Swiss space telescope CHEOPS is scheduled to begin its journey into space in mid-December on board a Soyuz rocket from the European Space Agency (ESA) in Kourou, French Guiana. CHEOPS is a joint mission of ESA and Switzerland, led by the University of Bern, in collaboration with the University of Geneva.
How nematodes outsmart the defenses of pests
The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become immune against these compounds in turn, which enhances their ability to fight the western corn rootworm, as researchers at the University of Bern show. This mechanism may contribute to improving biological pest control.
Breakthrough in malaria research
An international scientific consortium led by the cell biologists Volker Heussler from the University of Bern and Oliver Billker from the Umeå University in Sweden has for the first time systematically investigated the genome of the malaria parasite Plasmodium throughout its life cycle in a large-scale experiment.

The prize is being awarded today at the University of Bern.
Liquifying a rocky exoplanet
A hot, molten Earth would be around 5% larger than its solid counterpart. This is the result of a study led by researchers at the University of Bern. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar System and the understanding of Earth itself.
A planet that should not exist
Astronomers detected a giant planet orbiting a small star. The planet has much more mass than theoretical models predict. While this surprising discovery was made by a Spanish-German team at an observatory in southern Spain, researchers at the University of Bern studied how the mysterious exoplanet might have formed.
How to construct a protein factory
The complexity of molecular structures in the cell is amazing. Having achieved great success in elucidating these structures in recent years, biologists are now taking on the next challenge: to find out more about how they are constructed. A joint research project between two groups from the University of Bern and ETH Zurich now provides insight into a very unusual construction process in the unicellular parasite Trypanosoma brucei.

A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers led by the University of Bern on the basis of theoretical predictions matching observations. The “exo-Io” would appear to be an extreme version of Jupiter’s moon Io.
Major award for two Bernese medical projects
Prestigious grants from the USA go to two Bernese researchers: the biomedical scientists Marianna Kruithof-de Julio and Robert Rieben were the only researchers in Switzerland to receive a grant under two "Congressionally Directed Medical Research Programs", which primarily support research in the USA. This underlines the unique quality of medical research at the University of Bern.
Volcanoes shaped the climate before humankind
Five large volcanic eruptions occurred in the early 19th century. They caused cooling and – as a study led by the University of Bern shows – to drying in the monsoon regions and glaciers growing in the Alps. The study shows that the pre-industrial climate was not constant: if one takes this cold period as the starting point for current global warming, the climate has already warmed up more than assumed in the current discussions.
The climate is warming faster than it has in the last 2,000 years
In contrast to pre-industrial climate fluctuations, current, anthropogenic climate change is occurring across the whole world at the same time. In addition, the speed of global warming is higher than it has been in at least 2,000 years. That’s according to two studies from the University of Bern.
Four new professorships to drive forward diabetes research in Bern
The University of Bern and the Diabetes Center Berne (DCB) are together creating four professorships in the field of diabetes technology research and development. This will boost the international profile of diabetes research in Bern and strengthen its role as a center of medicine in the long term.
Sediments in Lake Geneva reflect the 2008 financial crisis
An analysis of sediment transport in the Rhône Valley yields surprising results: melting glaciers overcompensated for the effect of the increased number of hydropower plants. A reduction in construction activities due to the 2008 financial crisis could also be seen in the data. This comprehensive study, the first of its kind in Europe, brings important new knowledge, in particular for flood prevention.
Cancer control: Structure of important transport protein solved
For the first time, Bernese researchers have been able to solve the structure of a transport protein and thus to describe the functional mechanism that plays a significant role in the survival of cancer cells. This is an important step towards developing effective inhibitors and fight tumor growth.
Survey shows high levels of employee satisfaction at the University of Bern
On the whole, employees at the University of Bern are very satisfied or mostly satisfied with their work and, in general, have a high level of commitment. This is according to the results of the 2019 staff survey. One aspect which staff particularly enjoy is the diverse nature of their work. An up-to-date analysis of wage equality also yielded positive results: at the University of Bern, men and woman earn the same amount for work which is of equal value.
Bern in Space – celebrating 50 years since the moon landing
At the end of June, the University of Bern is holding a diverse science festival to mark the occasion of the 50th anniversary of the moon landing: a multimedia show on Bundesplatz will display milestones in Bernese space exploration, high-ranking representatives from the big space agencies will discuss the future of space exploration, there will be a chance to look up at the night sky from the Grosse Schanze – and rockets will be built.
"Goldilocks" neurons promote REM sleep
It has been a mystery why REM sleep, or dream sleep, increases when the room temperature is "just right". Neuroscientists from Bern show that melanin-concentrating hormone neurons within the hypothalamus increase REM sleep when the need for body temperature defense is minimized, such as when sleeping in a warm and comfortable room temperature. These data have important implications for the function of REM sleep.
A combination of insecticides and mite weakens honeybees
Today, scientists of the Institute of Bee Health of the University of Bern and the honeybee research association COLOSS have published an article in the peer-reviewed journal Scientific Reports that shows a synergistic time-lag interaction between the parasitic mite Varroa destructor and neonicotinoid insecticides reducing survival of winter honeybees, Apis mellifera. This article emphasizes the need to develop sustainable agricultural and apicultural schemes.
"Copying & pasting" a gene allows stickleback to live in freshwater habitats
Since the last ice age, stickleback have managed to emerge from the sea to colonise many freshwater waterbodies. Genetic analysis by Eawag researchers and colleagues from the University of Bern and the National Institute of Genetics in Shizuoka, Japan, now demonstrate that they achieved this thanks to additional copies of a metabolism gene.
Information and language in news impact prejudice against minorities
Researchers at the Institute of Psychology show how news about immigrants and language describing immigrants shape prejudice against immigrants and other social minorities, as part of the project «Immigrants in the Media». For instance, nouns used for describing the ethnicity of immigrants enhance prejudice against immigrants more than adjectives.
Bern Center for Precision Medicine inaugurated
The Bern Center for Precision Medicine (BCPM) of the University of Bern and Inselspital, University hospital of Bern, were officially opened today in the presence of Director of Education Christine Häsler. Häsler described the BCPM as a prime example of the development of new research centers, and strengthening Bern as a center of medicine.
Particulate matter from aircraft engines affects airways
In a unique, innovative experiment, researchers under the leadership of the University of Bern have investigated the effect of exhaust particles from aircraft turbine engines on human lung cells. The cells reacted most strongly to particles emitted during ground idling. It was also shown that the cytotoxic effect is only to some extent comparable to that of particles from gasoline and diesel engines.
Rare-Earth metals in the atmosphere of a glowing-hot exoplanet
KELT-9 b is the hottest exoplanet known to date. In the summer of 2018, a joint team of astronomers from the universities of Bern and Geneva found signatures of gaseous iron and titanium in its atmosphere. Now these researchers have also been able to detect traces of vaporized sodium, magnesium, chromium, and the rare-Earth metals scandium and yttrium.

An international collaboration with participation of the University of Bern has demonstrated for the first time in an interference experiment that antimatter particles also behave as waves besides having particle properties. This success paves the way to a new field of investigations of antimatter.
Spider venom is a dangerous cocktail
Spider venom does not only consist of neurotoxins but also of a multitude of dangerous constituents. Researchers of the University of Bern present a summary of many years of spider venom research in a new study and show how various substances present in spider venom interact with each other and thus effectively render the spider's prey defenseless.
"Flight recorder" of rocks within the Earth’s crust
Daniela Rubatto, Professor at the Institute of Geology at the University of Bern, was awarded the prestigious Bunsen Medal of the European Geosciences Union. It is an appreciation of her innovative research approach, which uses metamorphic zircon as a "flight recorder" of rocks within the Earth’s crust.
The oldest ice on Earth may be able to solve the puzzle of the planet’s climate history
A European research consortium, in which the University of Bern is involved in, wants to drill a 1.5 million year old ice core in Antarctica. An analysis of the climate data stored in the ice should contribute to a better understanding of the alternation between warm and cold periods.
Hurricanes going astray make for heavy rainfall in Europe
Tropical storms that move poleward influence the weather in Europe much more than previously supposed. A study from the Mobiliar Lab for Natural Risks at the University of Bern shows that the probability of heavy rainfall is twice as high when mid-latitude weather is disrupted by cyclones. These findings could ensure better extreme weather forecasts in the future.
Female roundworms produce clones of themselves
In the Mesorhabditis belari roundworm, the sole purpose of males is to help females produce clones of themselves. This unique form of reproduction was recently described by an international research team with participation of Peter Meister from the Institute of Cell Biology of the University of Bern.
Bernese Mars camera CaSSIS returns spectacular images
Three years ago, on 14 March 2016, the Bernese Mars camera CaSSIS started its journey to Mars with the "ExoMars Trace Gas Orbiter" spacecraft. The camera system developed at the University of Bern has been observing Mars from its primary science orbit since April 2018 and provides high-resolution, colour images of the surface. On 2 March 2019, CaSSIS also delivered its first image of InSight, NASA's lander on Mars.

The endowed professor has the objective to promote public oral health. Guglielmo Campus brings wide-ranging experience and considerable expertise to his post.
Neural networks predict planet mass
To find out how planets form astrophysicists run complicated and time consuming computer calculations. Members of the NCCR PlanetS at the University of Bern have now developed a totally novel approach to speed up this process dramatically. They use deep learning based on artificial neural networks, a method that is well known in image recognition.
The deep Southern Ocean is key to more intense ice ages
Over the last million years, ice ages have intensified and lengthened. According to a study led by the University of Bern, this previously unexplained climate transition coincides with a diminution of the mixing between deep and surface waters in the Southern Ocean. The study confirms that the Antarctic region plays a crucial role during periods of climate change.
European Southern Observatory Committee of Council meets in Bern
The European Southern Observatory (ESO) is Europe’s foremost organisation for astronomical research. Its giant telescopes provide advanced observational facilities at various sites in the Atacama Desert in Chile. Switzerland is one of the 16 countries which support ESO. The ESO Committee of Council, which currently has the University of Bern's astrophysicist Willy Benz as president, is to meet in Bern on 5 and 6 March.
Small and medium-sized towns are surprisingly innovative
Small and medium-sized towns are increasingly appearing on the radar of policy makers all over Europe. Findings from a project funded by the Swiss National Science Foundation on the role and significance of these towns in Switzerland show that national policy and planning overlook their potential.
Bern Center for Precision Medicine founded
Precision medicine "tailored" to individual patients is regarded as the medicine of the future. It is already being practiced at the University of Bern and Inselspital, Bern University Hospital. The new Bern Center for Precision Medicine will exploit synergies and strengthen the medicinal location in Bern.
Why a blow to the chest can kill or save you
It is still a mystery why a blow to the chest can kill people by inducing cardiac arrest yet save others that are in cardiac arrest. We may be one step closer to an answer, however, thanks to a device developed by researchers of the University of Bern and the EPFL that can replicate the experience in the laboratory.
"Better to dry a rocky planet before use"
Earth’s solid surface and clement climate may be in part due to a massive star in the birth environment of the Sun. Without its radioactive elements injected into the early solar system, our home planet could be a hostile ocean world covered in global ice sheets. This is demonstrated by computer simulations in which the National Centre of Competence in Research PlanetS, based at the University of Bern, was involved.
Drug-resistant tuberculosis: high mortality rate due to inaccurate tests
Inaccurate tests carried out on tuberculosis patients in developing countries often fail to reliably detect resistance to drugs, leading to incorrect treatment and a higher mortality rate. These are the results of study by an international group of researchers led by a team at the University of Bern published today.
Learning new vocabulary during deep sleep
Researchers of the University of Bern showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning.
Inequality promotes deforestation in Latin America
Agricultural expansion is the main cause of deforestation in Latin America. Improvements in agricultural productivity can either enable forest conservation, or promote more deforestation. A new University of Bern study highlights the role played by inequality: high inequality leads to more deforestation, while lower inequality improves the long-term protection of remaining tropical forests.
Discovery of bacterial signature of intestinal disease
Researchers from the Department of Biomedical Research of the University of Bern and the University Clinic of Visceral Surgery and Medicine of the Inselspital Bern, Switzerland, have discovered that changes in the composition of the intestinal bacteria in patients with chronic inflammatory bowel disease affect the severity of the disease and the success of therapy. The advance provides an important basis to improve treatment of these diseases.
Turbocharger for the cell machinery
Researchers of the University of Bern have discovered a new molecular regulatory mechanism in unicellular parasites which has never before been observed. RNA fragments do not act as brakes in the cell apparatus, but on the contrary as "stimulants": they boost protein production after periods of stress.
