How harmless is arsenic in seafood?
An interdisciplinary study from the University of Bern reveals that gut bacteria play a crucial role in converting arsenobetaine into toxic arsenic compounds. Results show that arsenobetaine, commonly found in seafood and previously considered harmless, is partly transformed into toxic arsenic compounds by the action of gut bacteria in the mammalian body.

Stimulating hypothalamus restores walking in paralyzed patients
Stimulating hypothalamus restores walking in paralyzed patients
The discovery that an unexpected brain region is crucial for walking recovery in mice with spinal cord injuries has led a deep brain stimulation therapy in humans. The approach restored enough leg control in two individuals with partial spinal injuries to walk unaided and even climb stairs. Researchers at EPFL and Lausanne University Hospital (CHUV), led by professors Grégoire Courtine and Jocelyne Bloch, have achieved a major milestone in the treatment of spinal cord injuries (SCI).

Brain stimulation effectiveness tied to learning ability, not age
A study from EPFL reveals that the effectiveness of brain stimulation on motor skills is determined by an individual's learning ability rather than age, highlighting the need for a more personalized approach to neurorehabilitation. As we age, our cognitive and motor functions deteriorate, which in turn affects our independence and overall quality of life.

A new clock to structure sleep
A new clock to structure sleep
Scientists at the FBM-UNIL have identified a new role for the locus coeruleus in sleep and sleep disorders. This brain region enables the transition between sleep states and the maintenance of essential unconscious vigilance. Stress disrupts its functions and impacts sleep quality. Sleep disorders affect a growing number of people, with potentially serious consequences for their health.

'Genetic Time Machine' Reveals Complex Chimpanzee Cultures
’Genetic Time Machine’ Reveals Complex Chimpanzee Cultures
Chimpanzees are known for their remarkable intelligence and use of tools, but could their cultures also evolve over time like human cultures? A new, multidisciplinary study led by the University of Zurich suggests that some of their most advanced behaviors may have been passed down and refined through generations.

Mapping Protease Activity: A Breakthrough in Drug Design
Mapping Protease Activity: A Breakthrough in Drug Design
Researchers at the Friedrich Miescher Institute (FMI) have developed an innovative tool that maps how proteases—enzymes that process proteins—interact with their targets. This tool sheds light on the highly selective nature of proteases, which were previously thought to be indiscriminate in their function.

The terrifying sound of the Aztec skull whistle
The terrifying sound of the Aztec skull whistle
The Aztec skull whistle produces a piercing, scream-like sound. According to a study by the University of Zurich, this sound has a strong frightening effect on the human brain. It is assumed that the Aztecs used this effect specifically in their sacrificial rituals in order to influence the participants emotionally.

Cause of the yo-yo effect deciphered
Cause of the yo-yo effect deciphered
Researchers at ETH Zurich have discovered a mechanism behind the yo-yo effect: fat cells have a memory that is based on epigenetics. Anyone who has ever tried to get rid of a few extra kilos knows the frustration: the weight drops initially, only to be back within a matter of weeks - the yo-yo effect has struck.

A new model to explore the epidermal renewal
A new model to explore the epidermal renewal
A UNIGE study has uncovered an unexpected mechanism used by the protein interleukin-38 to form condensates, major drivers of skin renewal. The mechanisms underlying skin renewal are still poorly understood. Interleukin-38 (IL-38), a protein involved in regulating inflammatory responses, could be a game changer.

Behavioural analysis in mice: more precise results despite fewer animals
Behavioural analysis in mice: more precise results despite fewer animals
Researchers at ETH Zurich are utilising artificial intelligence to analyse the behaviour of laboratory mice more efficiently and reduce the number of animals in experiments. There is one specific task that stress researchers who conduct animal experiments need to be particularly skilled at. This also applies to researchers who want to improve the conditions in which laboratory animals are kept.

Simulating how fruit flies see, smell, and navigate
Scientists at EPFL have advanced their NeuroMechFly model, simulating fruit fly movement in the real world. With integrated vision and smell, it helps us understand brain-body coordination, setting a path for neuroengineering's role in robotics and AI. All animals, large or small, have to move at an incredible precision to interact with the world.

Using CRISPR to decipher whether gene variants lead to cancer
Researchers at ETH Zurich have combined two gene editing methods. This enables them to quickly investigate the significance of many genetic mutations involved in the development and treatment of cancer. In recent years, scientists have created a range of new methods based on CRISPR-Cas technology for precisely editing the genetic material of living organisms.

The devastating effects of cocaine, even among young people
The devastating effects of cocaine, even among young people
Disfigured faces, impressively deformed. Wrinkles, swellings, parts of the lips that are no longer there, mouths and noses that have almost disappeared. These are the slow but inexorable effects of cocaine. Professor Matteo Trimarchi, Professor of Otorhinolaryngology at the Faculty of Biomedical Sciences of Università della Svizzera italiana (USI) and Head of Otorhinolaryngology Ente Ospedaliero Cantonale (EOC ), spoke about these severe effects, even among the youngest, in an interview with La Domenica.
