Des bureaux du parti "Les Ecologistes" vandalisés à Toulouse, Limoges, Nevers etc. parce qu'ils sont contre la loi Duplomb et soutiennent la pétition... Et pourtant, ça ne fait pas la Une des médias.

Le ministre de l'Intérieur Bruno Retailleau va-t-il condamner ces violences ?

Science Advances’ special issue on women’s health highlights a growing wave of research focusing on women’s unique biological and psychological experiences. Articles cover a range of studies from the interplay between menopause and Alzheimer’s risk to the menstrual cycle’s influence on the brain-heart connection. It also describes the opportunities pregnancy provides to research aspects of both physical and mental health. By prioritizing women’s unique physiological and psychological experiences, research can expand the frontiers of knowledge in ways that benefit everyone.
