Researchers at the University of Bern have investigated the influence of siblings on the development of lifelong social competence in African cichlids. In an experiment, they show for the first time that two factors must work together for this effect to occur: Both the number of siblings present during early life and the quality of their interactions with them are crucial.

Researchers at the Inselspital, Bern University Hospital, and the University of Bern have, for the first time, directly measured how the human brain exchanges probing signals when asleep and when awake. Using electrodes temporarily implanted in the brain for clinical reasons, they were able to track the flow of signals between deep brain regions and the cerebral cortex with millisecond accuracy over a period of 24 hours.

An international research team, with participation of the University of Bern, has conducted the world's first comprehensive genetic study of cancer in domestic cats. The study shows that some of the genetic changes in cat tumors closely resemble those found in human cancers. These parallels open up new perspectives for developing targeted cancer therapies, particularly for breast cancer.

First the rocky planets, very close to their star, then the gas giants: this is the order in which scientists have hitherto conceived of the hierarchy of planets. A conception that corresponds to our Solar System but also to most of the planetary systems identified to date. However, the recent discovery of a new planet around the star LHS 1903 by the CHEOPS space telescope is now challenging this theory.

For the first time, researchers at the University of Bern and Inselspital, Bern University Hospital, have shown that temperature signals from the skin are processed in the brain, influencing REM sleep and sleep-related disorders. These new findings enhance our understanding of brain-body interactions that regulate sleep and provide novel therapeutic strategies for sleep-wake rhythm disorders, such as narcolepsy.

Researchers at the University of Bern have been able to show that simple measures to promote biodiversity, such as the installation of branch and stone piles, boost stoat populations in agricultural areas in Switzerland. This is particularly true if the measures are professionally supervised, planned and coordinated.

An old puzzle in particle physics has been solved by a research group involving TU Wien, the University of the Pacific, and the University of Bern: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. Quantum field theories are the foundation of modern physics.

A new study led by the University of Bern has discovered a large number of bright streaks, also known as "lineae", on Mercury, which are presumably caused by the outgassing of volatile material from the planet's interior. This indicates that Mercury is not a dead planet, as previously assumed, but might in fact be geologically active.

Using images from cameras on Mars orbiters, an international research team led by the University of Bern has discovered structures on Mars that are very similar to classic river deltas on Earth. These are traces of rivers that have deposited their sediments into an ocean. This shows that Mars was a "blue planet" around three billion years ago.

There is no evidence for the existence of sterile neutrinos - a fourth type of the elementary neutrino particle. This is shown by the international MicroBooNE collaboration at the US research center Fermilab with the participation of the University of Bern. The results confirm the standard model of particle physics and rule out the possibility that sterile neutrinos are the explanation for certain anomalies in earlier physics experiments.

Low blood sugar (hypoglycemia) is a critical diabetes-related condition. Researchers at the Inselspital, Bern University Hospital and the University of Bern have now shown for the first time that the human voice can even reveal early signs of hypoglycemia. Recordings made with the microphone of an ordinary smartphone and analyzed using artificial intelligence could make diabetes management safer and easier in the future.

An international research team has identified a previously unknown function of the intestinal nervous system. The study reveals that the intestinal nervous system plays a key role in regulating both the composition and stability of the intestinal barrier. Disruption of this protective mechanism can lead to the development of allergies.

Researchers from the University of Bern and Inselspital, Bern University Hospital, in collaboration with over 50 global institutions, have launched the first comprehensive atlas of the mouse gut microbiome. This landmark study synthesizes data from mouse microbiomes across six continents, revealing that metabolic functions remain relatively stable despite microbial diversity.

A study from the University of Bern and international collaborators shows for the first time that biological invasions don't change ecosystems in a single, uniform way. Some impacts, most notably losses of native plant diversity caused by invasive plant species, are persistent and intensify with time, while others, such as shifts in soil carbon and nutrients, often fade as invasions age.

Researchers at the Inselspital, Bern University Hospital, and the University of Bern, in collaboration with researchers at the Mayo Clinic, Rochester, USA, have developed and tested a novel gene therapy that successfully corrects a life-threatening genetic cardiac arrhythmia in an animal model. The procedure restores the normal function of the affected cardiac ion channel and opens up new perspectives for the future treatment of both rare and common cardiac arrhythmias.

A simple change in species composition can impact the course of evolution: A research team from the University of Bern and the University of British Columbia in Canada shows that the presence of just one other fish species is enough to drive the emergence of new species in sticklebacks. It has long been assumed that adaptation to different habitats plays an important role in the evolution of new species.

On Mars, dust devils and winds reach speeds of up to 160 km/h and are therefore faster than previously assumed: This shows a study by an international research team led by the University of Bern. The researchers analyzed images taken by the Bernese Mars camera CaSSIS and the stereo camera HRSC with the help of machine learning.

The Bernese Mars camera CaSSIS aboard ESA's ExoMars Trace Gas Orbiter reveals the glowing atmosphere of Mars in unprecedented detail. Slices from the edge of Mars reveal a layered atmosphere of delicate complexity. A European spacecraft has captured a luminous mille-feuille of dust enveloping the Red Planet in unprecedented detail.

Researchers from the University of Bern have developed an Artificial Intelligence (AI) model capable of predicting the architecture of planetary systems and subsequently inferring the presence of yet-to-be-discovered planets. They use the so-called Transformer architecture which is the basis of the Large Language Models powering tools like the recently launched Swiss model Apertus or chatbots such as ChatGPT.

After the formation of the Solar System, it took a maximum of three million years for the chemical composition of the Earth's precursor to be completed. This is shown by a new study by the Institute of Geological Sciences at the University of Bern. At this time, however, there were hardly any elements necessary for life such as water or carbon compounds on the young planet.
