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.

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.
