Electrical Tides (Zoomed) - Magnified approximately 20×, this image reveals the microscopic barbules of a peacock feather. Their repeating arrangement evokes the rhythmic crests of ocean waves illuminated beneath a deep blue sky, despite depicting a structure only fractions of a millimeter across. The brilliant blue is generated not by pigment but by structural coloration: precisely organized nanostructures interact with light through interference, producing vivid iridescence. By removing all familiar visual cues, the image transforms a biological surface into an abstract seascape shaped entirely by the physics of light. Image by Emre Can, Marmara University

Atomic‐force microscopy image (10 × 10 μm²) of an amyloid-like peptide dried on freshly cleaved muscovite mica. The peptide aggregates form irregular, leaf-like crystalline patterns reminiscent of snowflakes. Image by Christian Bortolini, National Physical Laboratory

SEM-TKD imaging of dislocation dynamics near a grain boundary and carbides in a Nickel-based superalloy. Various nanoscale features are readily observed: dislocation looping, arrays, interactions, etc. The RGB diodes automatically colour the picture in a psychedelic fashion. Image by Yuanbo Tang
