How harmless is arsenic in seafood?

Health - Dec 6
Health

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.

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).
