Article Abstract
Dynamic visual appearance, from the capacity of organisms to rapidly alter color or pattern of the body, is typically achieved through physiological color-change and/or bioluminescence. Since these processes often tune appearance to changing ecological conditions, even small errors in performance may impact fitness. Recent discoveries in the field of photobiology have led to an emerging hypothesis that photoreceptive systems associated with appearance-altering tissues function in the self-assessment of dynamic visual appearance. We outline the ecological significance of that self-assessment, the apparent convergence upon strategies to do so, and the implications of these strategies for: (i) the diversity of taxa that employ these strategies, and (ii) the evolution of visual pathways and optical structures previously only understood to serve ocular vision.

Ultrasonography in veterinary medicine serves a vital role in the diagnosis and management of various medical conditions by allowing noninvasive visualization of internal structures. Veterinary students face many challenges in gaining hands-on experience with ultrasound equipment and developing competencies in ultrasonography. This is largely due to the limited access and ethical dilemmas of live animal models and the high cost of commercial phantoms.

The electromobility shift assay (EMSA) is a popular and productive molecular biology tool for studying protein-nucleic acid interactions. EMSA is a technique applied to the revelation of the binding dynamics of proteins, like transcription factors, to DNA or RNA. There are ample essential phases in the technique.

Volume correlative light and electron microscopy (vCLEM) is a powerful imaging technique that enables the visualization of fluorescently labeled proteins within their ultrastructural context. Currently, vCLEM alignment relies on time-consuming and subjective manual methods. This paper presents CLEM-Reg, an algorithm that automates the three-dimensional alignment of vCLEM datasets by leveraging probabilistic point cloud registration techniques.

Acute lymphoblastic leukemia (ALL) preferentially localizes in the bone marrow (BM) and displays recurrent patterns of medullary and extra-medullary involvement. Leukemic cells exploit their niche for propagation and survive selective pressure by chemotherapy in the BM microenvironment, suggesting the existence of protective mechanisms. Here, we established a three-dimensional (3D) BM mimic with human mesenchymal stromal cells and endothelial cells that resemble vasculature-like structures to explore the interdependence of leukemic cells with their microenvironment.

While non-destructive in-line monitoring at manufacturing sites is essential for safe distribution cycles of pharmaceuticals, efforts are still insufficient to develop analytical systems for detailed dynamic visualisation of foreign substances and material composition in target pills. Although spectroscopies, expected towards pharma testing, have faced technical challenges in in-line setups for bulky equipment housing, this work demonstrates compact dynamic photo-monitoring systems by selectively extracting informative irradiation-wavelengths from comprehensive optical references of target pills. This work develops a non-destructive in-line dynamic inspection system for pharma agent pills with carbon nanotube (CNT) photo-thermoelectric imagers and the associated ultrabroadband sub-terahertz (THz)-infrared (IR) multi-wavelength monitoring.
