Description When someone is given the opportunity to utilize creative liberty, they have access to an infinitely diverse palette of colors, mediums, patterns, and shapes to form a unique amalgamation of artistic styles that conveys different ideas and stories. This painting has been created using watercolor paint, permanent markers, acrylic paint, and multicolored glitter to portray a dream-like, tropical bird in flight. The background of the painting is not as detailed as the prominent, avian figure in question, and that is to leave some ambiguity as to the exact whereabouts of this majestic creature, which is to be determined solely by the observer.

Among hornbill birds, the critically endangered helmeted hornbill (Rhinoplax vigil) is notable for its casque (a bulbous beak protrusion) being filled with trabeculae and fronted by a very thick keratin layer. Casque function is debated but appears central to aerial jousting, where birds (typically males) collide casques at high speeds in a mid-flight display that is audible for more than 100 m. We characterized the structural relationship between the skull and casque anatomy using X-ray microtomography and quantitative trabecular network analysis to examine how the casque sustains extreme impact.

Article Synopsis
- The study introduces a highly efficient TiO meta-atom-based near-infrared disordered metalens inspired by bird's eye hyperuniform distribution, analyzed using the finite-difference time-domain method.
- The disordered metalens demonstrates a remarkable focusing efficiency of 84.39% at 820 nm, showing it can produce images similarly to traditional ordered structures.
- The findings suggest potential applications in advanced imaging, sensing, and spectroscopic technologies, including lidar, medical devices, and holography, due to comparable optical properties with periodic metalens structures across a wavelength range of 770 to 970 nm.

Magneto-responsiveness in living organisms, exemplified by migratory birds navigating vast distances, offers inspiration for soft robots and human-computer interfaces. However, achieving both high magneto-responsiveness and resilient mechanical properties in synthetic materials has been challenging. Here, we develop magneto-iono-elastomers (MINEs), combining exceptional magnetization [2.

The COVID-19 pandemic highlighted the urgent need for effective surface disinfection solutions, which has led to the use of mobile robots equipped with ultraviolet (UVC) lamps as a promising technology. This study aims to optimize the navigation of differential mobile robots equipped with UVC lamps to ensure maximum efficiency in disinfecting complex environments. Bio-inspired metaheuristic algorithms such as the gazelle optimization algorithm, whale optimization algorithm, bat optimization algorithm, and particle swarm optimization are applied.
