Researchers at the University of Vienna have developed fluorescent peptide tracers that can simultaneously visualise and activate the oxytocin receptor. This receptor–also known as the love/bonding hormone receptor–plays a key role in processes related to social behaviour, health and disease. These tracers create new possibilities for imaging and functional analysis in various biological systems–with far-reaching implications for fundamental research as well as for breast cancer diagnostics and therapy. The development of the tracers is described in the current issue of the renowned journal Angewandte Chemie, International Edition, and the tracers have recently been patented.

Changing habits like quitting smoking or managing stress is hard – but crucial. Motivational interviewing (MI), a proven counseling method that sparks internal motivation, works well but isn’t widely used due to time and training demands. Now, AI tools like ChatGPT are stepping in, simulating MI conversations anytime, anywhere. A new review shows these tools are promising and well-received, but questions remain: Do they truly reflect MI’s core principles? Can they drive real, lasting change? The answer could reshape digital health interventions.

The American Association of Immunologists (AAI) today announced the launch of Immunology Explained, a public communications initiative designed to connect people everywhere with clear, science-based information about the immune system and its impact on health. Immunology Explained will cover a broad range of immunology topics including vaccines, autoimmunity, cancer immunotherapy, and infectious diseases.
