Smart AI coach helps smokers quit using reinforcement learning

Nele Albers of Delft University of Technology (The Netherlands) uses AI coaches to help smokers quit smoking and vaping for her doctoral dissertation. She has developed an AI coach that uses psychologically informed reinforcement learning (RL), a form of machine learning in which a model learns through rewards, similar to how humans learn behaviors. Albers based her research on insights from behavior change theories and data from three large-scale studies with more than 500 participants each.

Sustainable anesthesia: An operating room lowers CO₂ emissions by 80%

Universitätsmedizin Berlin has reduced the annual CO2 emissions originating from gases used for anesthesia by over 80% since 2018. This reduction in carbon emissions was achieved by using climate-friendly anesthetics in the operating room. As a study published in the journal Anesthesia & Analgesia demonstrates, education—and in particular, fundamental decisions—were the keys to success.
