Lake Inle, a pristine lake in Myanmar, is known to harbor a number of endemic aquatic species and is a home to an enigmatic cyanobacterium Oscillatoria kawamurae, which was first reported in Lake Biwa (Japan). Macroscopic trichome (upper left), microscopic image (upper middle). Photos by Phong San (Lake Inle) and Nanda Kyaw Thu (O. kawamurae). See Thu et al. in this issue.

Left panel: Lateral view of a lenticular cell of Valonia utricularis at the beginning (upper) and the end (lower) of a 22-hr observation. Arrowheads with numbers indicate carbon particles along the cell outline. Right panel: (upper) Changes in cell outline and position of the numbered carbon particles in the lenticular cell at 2-hr intervals. (lower) The segmental extension profile of the lenticular cell showing the anisotropic cell surface growth. Numbers represent those used for labelling the carbon particles. See Mine et al. in this issue for details.
An optical fan was demonstrated to screen leukemia cells from the blood sample at the single‐cell level in a noninvasive and noncontact manner. Further details can be found in the article by Xiaoshuai Liu, Yuchao Li, Xiaohao Xu, Yao Zhang, Baojun Li ( e201900155 ).
Infrared spectroscopy enables insight into light‐activated riboflavin‐induced collagen cross‐linking for future intervertebral disc treatment and repair. Further details can be found in the article by Ioannis Vasilikos, Julian Haas, Graciosa Q. Teixeira, Julia Nothelfer, Cornelia Neidlinger‐Wilke, Hans‐Joachim Wilke, Andreas Seitz, Demetrios G. Vavvas, Josef Zentner, Jürgen Beck, Ulrich Hubbe, and Boris Mizaikoff ( e202000110 ).
A high‐efficiency computer‐aided diagnostic model of ovarian cancer was developed, integrating SHG imaging technology for non‐invasive imaging of living tissue and machine learning method based on radiomics and TPOT. This model can rapidly, non‐destructively, and accurately perform ovarian cancer diagnosis and has great potential in improving diagnostic efficacy and efficiency of medical pathologists. Further details can be found in the article by Guangxing Wang, Yang Sun, Youting Chen, Qiqi Gao, Dongqing Peng, Hongxin Lin, Zhenlin Zhan, Zhiyi Liu, and Shuangmu Zhuo ( e202000050 ).
A comparative analysis of intrinsic skin aging between Caucasian and Asian subjects by slide‐free in vivo harmonic generation microscopy is reported. The cellular and nuclear areas of basal cells in Caucasians and Asians are found to increase at the same rate, ideal for scoring age. On the other hand, the viable epidermis thickness, the dermal papilla volume and height in Caucasians are found to decrease faster than those in Asians. Further details can be found in the article by Kuan‐Hung Lin, Yi‐Hua Liao, Ming‐Liang Wei, and Chi‐Kuang Sun ( e201960063 ).
The figure shows the detailed morphology of vasculature and dynamic changes of the blood vessel diameter and density and the oxygen saturation in the blood vessels in fetal brain after acute prenatal ethanol exposure in the second‐trimester equivalent murine model obtained using a real‐time photoacoustic tomography (PAT) system. Further details can be found in the article by Tianqi Shan, Yuan Zhao, Shixie Jiang, Huabei Jiang ( e201960161 ).
This study presents a novel intraoperative in vivo imaging approach which harnessed Cerenkov luminescence (CL) to detect primary and metastatic colorectal cancer (CRC) using clinically approved radiopharmaceuticals. In the mice and swine experiments, the proposed approach effectively improved the effect of CRC surgery. The approach is believed to be promising for utilizing CL in open surgery. Further details can be found in the article by Zeyu Zhang, Yawei Qu, Yu Cao et al. ( e201960152 )

Optical Coherence Tomography angiography (OCTA) is widely used to image chorioretinal vasculature, with contrast that derives from scattering and motion of red blood cells (RBCs). In the rat eye, a scattering tracer highlights vertical vessels which are not visualized by intrinsic RBC scattering alone. The dependence of microvessel OCTA on angular orientation, explored in this work, represents a potential artifact that should be considered in the clinical interpretation of OCTA. Further details can be found in the article by Jun Zhu, Marcel T. Bernucci, Conrad W. Merkle, and Vivek J. Srinivasan ( e202000090) .
