Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Icebergs on the Bosporus and a frozen Black Sea: an international study by the University of Bern with the participation of the Austrian Academy of Sciences shows how volcanic eruptions on Iceland influenced the European climate in the early Middle Ages and led to severe winter cooling anomalies. It was one of the coldest winters the region has ever experienced: In 763, large parts of the Black Sea froze over and icebergs were sighted on the Boporus.

Spatial-temporal detection of apoptotic cell death in live-cell imaging
Spatial-temporal detection of apoptotic cell death in live-cell imaging
Apoptotic cell death is a crucial mechanism that contributes to tissue homeostasis and prevents the onset of several diseases. However, this phenomenon is challenging to identify within microscopy movies that can encompass thousands of cells. Led by Santiago Gonzalez, the recent study carried at the Institute for Research in Biomedicine (IRB) in Bellinzona, affiliated with USI, introduces ADeS, an innovative approach based on artificial intelligence for the automatic detection of apoptotic cells in microscopy movies.

Understanding muscle regeneration with zebrafish
Understanding muscle regeneration with zebrafish
In humans, muscles can only regenerate from small injuries, such as those resulting from sporting activities. After an accident or combat injury, large wounds often cause deep damage to muscles, which fail to regenerate and scar. Some animals, on the other hand, replace injured body parts perfectly.

The enemy within: How pathogens spread unrecognized in the body
The enemy within: How pathogens spread unrecognized in the body
Some pathogens hide inside human cells to enhance their survival. Researchers at the University of Basel, have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.

Energy scientists unravel the mystery of gold's glow
Energy scientists unravel the mystery of gold's glow
Researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries. Luminescence, or the emission of photons by a substance exposed to light, has been known to occur in semiconductor materials like silicon for hundreds of years.

Surprising reversal in quantum systems
Surprising reversal in quantum systems
Researchers at ETH Zurich have studied topological effects in an artificial solid, making surprising observations. The new insights into topological pumping could be used for quantum technologies in the future. In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one has to do just that.

Happily ever after
Happily ever after
Many people aspire to a successful partnership. But is this success determined by destiny, or does it result from working on the relationship? Researchers from the University of Basel have investigated the role of people's inner convictions on how they approach a relationship and how satisfaction develops over time.

CEOs' Human Concern Translates into Higher Stock Price
CEOs’ Human Concern Translates into Higher Stock Price
Compassionate leadership has tangible benefits: CEOs' expressions of empathy correlate with positive stock performance, a study led by the University of Zurich shows. The researchers analyzed data from conference calls between CEOs and financial analysts during the COVID-19 pandemic. The COVID-19 pandemic prompted an unprecedented financial crisis.

Perfect balance: How the brain fine-tunes its sensitivity
Perfect balance: How the brain fine-tunes its sensitivity
A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. University of Basel researchers report in the journal Nature how neuronal networks in the mouse brain are fine-tuned.

Antisemitism in the history of Raiffeisen?
On behalf of Raiffeisen Switzerland Cooperative, researchers examined the beginnings of the Raiffeisen movement in Switzerland. Their focus was on antisemitism as well as Raiffeisen during National Socialism. Raiffeisen Group in Switzerland today has 219 cooperative Raiffeisen banks. It is based on the cooperative movement started by F.W. Raiffeisen in Germany around 1860.

An ink for 3D-printing flexible devices without mechanical joints
An ink for 3D-printing flexible devices without mechanical joints
Researchers are targeting the next generation of soft actuators and robots with an elastomer-based ink for 3D printing objects with locally changing mechanical properties, eliminating the need for cumbersome mechanical joints. For engineers working on soft robotics or wearable devices, keeping things light is a constant challenge: heavier materials require more energy to move around, and - in the case of wearables or prostheses - cause discomfort.

Understanding carbon release from the tundra
Understanding carbon release from the tundra
The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into a carbon source, exacerbating the effects of climate change. Open-top chambers (OTCs) in Latnjajaure, Sweden provide a controlled environment to study simulated warming of the tundra ecosystem.
