Birds use their claws to perch on branches, which helps them to recover energy and observe their surroundings; however, most biomimetic flapping-wing aircraft can only fly, not perch. This study was conducted on the basis of bionic principles to replicate birds' claw and wing movements in order to design a highly biomimetic flapping-wing aircraft capable of perching. First, a posture conversion module with a multi-motor hemispherical gear structure allows the aircraft to flap, twist, swing, and transition between its folded and unfolded states.

The fovea, a pit in the retina, is crucial for high-acuity vision in humans and is found in the eyes of other vertebrates, including certain primates, birds, lizards, and fish. Despite its importance for vision, our understanding of the mechanisms involved in fovea development remains limited. Widely used ocular research models lack a foveated retina, and studies on fovea development are mostly limited to histological and molecular studies in primates.
