A study showing that anxiety observed in laboratory mice is highly dependent on their environment. Transferring them to an enriched environment that closely mimics natural conditions rapidly reduces anxious behaviors, highlighting the importance of environmental experiences in the assessment of threats and animal well-being.

This Order repeals that of April 3, 2014. It reinforces animal health and protection rules for pet-related activities, providing a clear and detailed regulatory framework for the activities of shelters, breeding establishments, educators and traders, taking into account the particular needs of each individual species. Health rules must now be instituted by all establishments.

Article on environmental enrichment in captive animals. Conditions in captivity restrict the satisfaction of animals' physiological and ethological needs. Lack of stimulation and stressful practices can be detrimental to their welfare and affect the quality of scientific research carried out on these animals.

A scientific review of the long-term phenotypic consequences of painful neonatal procedures in rodents, whose response to pain, fear and anxiety stimuli is initially reduced and then becomes exacerbated with age. These procedures result in cognitive, social and reproductive deficits, which can be transmitted to offspring. The implications for the long-term welfare of farm animals following early painful procedures are discussed.

Preview: “The investigation of emotions is hindered by a lack of rapid and precise readouts of emotion states in model organisms. Dolensek et al. identified facial expressions as innate and sensitive reflections of the internal emotion state in mice.”

This article aims to bring together in a single document the knowledge acquired over recent years on the mechanisms of the appearance and modulation of pain in animals. The review is divided into three parts. The first describes the different stages of development, transmission and integration of the nociceptive messages involved in the onset of pain (sensory and emotional components). The second describes the different types of modulation that can activate or inhibit the transmission of nociceptive messages. The third describes the different neurophysiological processes that accompany pain and can modulate it (inflammation, activation of the autonomic nervous system and the neuroendocrine system).
