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. These findings raise new questions about the safety of seafood consumption.
Bird-inspired drone can jump for take-off
Researchers have built a drone that can walk, hop, and jump into flight with the aid of birdlike legs, greatly expanding the range of potential environments accessible to unmanned aerial vehicles.
How the latest sensors analyse body fluids
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.
CRISPR-Cas technology: balancing efficiency and safety
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.
A keener eye for the invisible
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.
Restaurant ratings in test
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.
Better protection for Earth’s dark sky
For millennia humans have been inspired by the stars but this may soon be a thing of the past due to a significant increase in the numbers of satellites, potentially limiting our view of the night sky. scientists are part of a global initiative to better protect Earth's Dark and Quiet Skies.
CLOUD experiment resolves puzzle of new aerosol particles in upper troposphere
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.
Decoding protein interactions: A step toward personalized medicine
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.
The social status of an AI influences its acceptance
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.
