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.

CRISPR-Cas9 system with PEG-mediated transfection was efficient for genome editing in Ulva prolifera. U. prolifera (left) and male gametes (middle). Wild type (upper right) and the genome-edited strain (lower right) cultured in 2-FA selection medium, and each mutation site on the APT gene. See Ichihara et al. in this issue.
Scanning electron micrographs of two members of the marine diatom genus Nagumoea, N. africana (the left four photos) and N. serrata (the right two). This genus is characterized as unique by the ladder-like structure of its internal valve as shown in the image. Morphology and molecular phylogeny of this genus are reported by Sugawara et al. in this issue.

Upper middle: Live cell showing chloroplast structure in valve view. Upper right: DIC image of a frustule in valve view. Lower: SEM image of the external valve showing peripheral and apical spines, siliceous slats and tri‐undulate valve shape. See Roy et al. in this issue. Cover picture from: Article link here
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 ).
Beautiful underwater view of an edible brown alga, Sargassum fusiforme (Fucales, Phaeophyceae) at the rocky shore in Sakurajima, Kagoshima, Japan (Photo by Ryuta Terada). Characteristic responses of the PSII photochemical efficiency on desiccation and salinity gradients in S. fusiforme are reported by Yonemori 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.

A type of compact and cost‐effective light‐sheet imaging device, termed sub‐voxel‐resolving light‐sheet add‐on module (SLAM), is developed to cooperate with conventional 2D epifluorescence microscope, allowing high‐contrast, resolution‐improved 3D imaging of various biological samples at high throughput. Further details can be found in the article by Fang Zhao, Yicong Yang, Yi Li, et al. ( e201960243 ).
Immunofluorescence image of Plasmodium berghei sporozoites (red) in HeLa cells 1.5 hours post infection. The parasitophorous vacuole membrane (PVM) that surrounds the parasites was stained with antibodies against the PVM‐resident protein UIS4 (grey). DNA was stained with DAPI (blue). Imaging was performed on a Leica SP8 confocal microscope. For further details, readers are referred to the article by Bindschedler et al. on p. e13271 of this issue.

Transcranial photobiomodulation (tPBM) with wavelength at 808 nm was applied to a rat model of acute seizures. The tPBM successfully attenuated convulsive status epilepticus, and the tPBM was shown to reduce the apoptosis of parvalbumin‐positive interneurons (PV‐INs) and preserved the integrity of perisomatic inhibitory network of PV‐INs to principle cells in the hippocampus. Further details can be found in the article by Chung‐Min Tsai, Shwu‐Fen Chang, and Hsi Chang ( e202000095 ).
