See if you can find the 8 differences in each set of images.

Nano-stingray

Scanning electron micrograph of an epoxy-nanocomposite fracture surface reminiscent of a stingray gliding through the ocean. The carbon nanotube tail acts as a high-strength deterrent, enhancing durability against attack from predators.

Feather and fan

This otherworldly landscape is a polarized microscopy photograph of a perylene derivative thin film. This technique allows the light to pass through crystalline areas of the imaged film, while amorphous regions remain dark. The combination of this technique and Nature's talent to assemble organic crystals creates an abstract tableau that resembles feathers, fans, wings, and gems.
