Many animals are capable of rapid dynamic colour change, which is particularly well represented in fishes. The proximate mechanisms of dynamic colour change in fishes are well understood; however, less attention has been given to understanding its ecological relevance. In this study, we investigate dynamic colour change in zebrafish () across multiple contexts, using a protocol to image the colouration of live fish without anaesthesia under standardized conditions.

Article Synopsis
- * A new model called LFGB-YOLO is proposed, featuring two main components: the Light-Fast part for efficient feature extraction, and the GB-Neck part for effective feature fusion, enhancing detection capabilities.
- * Experimental results show that LFGB-YOLO outperforms existing models like YOLOv5n and YOLOv8, with significant improvements in various performance metrics such as Recall and F1 score, proving effective in challenging lighting environments.

Article Synopsis
- Melasma is a common, chronic skin condition that mainly affects women, presenting as dark patches on the face and is often perceived as a serious cosmetic issue.
- A survey conducted among 199 dermatologists in Turkiye revealed that the majority of patients with melasma are females between the ages of 30 to 40, with mixed melasma being the most common type.
- The study found that topical treatments, particularly Kligman's formula, are most frequently used, while oral treatments like tranexamic acid are less common, and there's a significant recurrence rate of 41%-60%, suggesting the need for better management strategies.
