A new generation of wearable sensors will fundamentally change medicine. Researchers at ETH Zurich have now published an overview showing what is possible with such sensors and what questions their developers should consider to ensure their successful future use. Using a smartwatch to measure pulse, and a smartphone app to monitor blood pressure: wearable sensors already track some of the body's vital functions fairly reliably, and some of these devices can already be used in clinical diagnostics.

In a paper published today in the journal Nature , the CLOUD collaboration at CERN reveals a new source of atmospheric aerosol particles that could help scientists to refine climate models. Aerosols are microscopic particles suspended in the atmosphere that arise from both natural sources and human activities.

Researchers have uncovered a serious side effect of using the CRISPR-Cas gene scissors. A molecule designed to make the process more efficient destroys parts of the genome. Genome editing with various CRISPR-Cas molecule complexes has progressed rapidly in recent years. Hundreds of labs around the world are now working to put these tools to clinical use and are continuously advancing them.

Understanding how proteins interact is essential to decoding cellular processes and communication. In a groundbreaking study, researchers at the Friedrich Miescher Institute (FMI) have explored how every possible mutation in a protein affects its ability to bind with its partners, shedding light on how mutations influence cellular functions and the evolution of proteins.

From smart textiles to self-driving cars: researchers are developing new types of detectors for infrared radiation that are more sustainable, flexible and cost-effective than conventional technologies. The key to success is not (only) the composition of the material, but also its size. The ubiquity of infrared detectors What do motion detectors, self-driving cars, chemical analyzers and satellites have in common' They all contain detectors for infrared (IR) light.

How do people evaluate the performance of an AI system? New research results from a group of sociologists at the University of Lucerne show that even non-human actors are subject to social prejudices. Imagine two doctors with identical skills and impeccable performance: Would your judgment of their actions change if one worked in a world-class hospital or was male or female?

Study reveals differences between ratings among the population Discrepancies in restaurant ratings investigated: A new study by the University of Applied Sciences Graubünden shows how strongly ratings of restaurants differ among the population. While cleanliness, value for money and service quality are generally appreciated, other criteria such as vegan dishes, accessibility and portion sizes vary greatly.

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).

Since more and more deciduous trees are being planted in Swiss forests, whose wood is often burned directly, innovative ideas for a cascade use are in high demand in order to utilize Swiss hardwood more sustainably.

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.

New research from the University of Zurich, based on data from more than 28,000 caregivers in three countries, shows that the longer individuals spend caring for loved ones, the more their well-being suffers, regardless of the caregiving context. These findings underscore the need for policy discussions to alleviate the burden of informal care.

A research team led by scientists has developed a system that provides key insight into the relationship between sea spray aerosols, sea state and atmospheric conditions. The system was mounted on an icebreaker and carried across vast regions of the Arctic to collect and analyze valuable data. Aerosols are tiny particles suspended in the air that play an important role in cloud formation, precipitation and the reflection of sunlight back into space.

A team from the University of Geneva and the HUG has revealed that the majority of tweets published about obesity between 2019 and 2022 convey negative feelings.

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.

When asked in Arabic about the number of civilian casualties killed in the Middle East conflict, ChatGPT gives significantly higher casualty numbers than when the prompt was written in Hebrew, as a new study by the Universities of Zurich and Constance shows. These systematic discrepancies can reinforce biases in armed conflicts and encourage information bubbles.

By analyzing a Martian meteorite, scientists from the University of Lausanne and Curtin University have discovered traces of water dating back 4.45 billion years in the crust of Mars, i.e. to the beginning of the Red Planet's formation. This new information reinforces the hypothesis that Mars may have been habitable at some point in its history.

Since the 1980s, its been known that a mysterious contaminant forms in chloraminated drinking water, but only now has a Swiss-American research team been able to identify the unknown product in US drinking water systems. A team of researchers from the United States and Switzerland have reported the discovery of a previously unknown compound in chloraminated drinking water.

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.

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.
