Demon Slayer, a well-known anime depicting a bamboo muzzle worn by a character, has been investigated from various perspectives. However, its scientific perspective particularly the depiction of bamboo muzzle remains unexplored. To fill this gap, a new study compared the lengths of bamboo segments shown in anime illustrations with measurements from real plants and mathematical models. The findings reveal major differences in the structure of anime bamboo and actual bamboo, enhancing public understanding about bamboo.

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by independently engineering the intensity and polarization of light along the propagation direction. By encoding volumetric information into structured beam arrays, the system enables high-fidelity 3D reconstruction and a new physical-layer optical encryption strategy based on the depth and polarization keys. This compact technology opens promising opportunities for secure communication, optical storage, and next-generation 3D displays.

Satellite navigation systems underpin modern society, supporting aviation, transportation, telecommunications, and scientific monitoring. 

POSTECH Professor Inseok Hwang’s team unveils ArithMotion, enabling socially-aligned avatar motions with simple arithmetic inputs.

However, productivity in the industry is still limited due to early-life bottlenecks, with high mortality rates caused by disease outbreaks, environmental changes and stress.

Now, a team from the Okinawa Institute of Science and Technology (OIST) has developed a scalable aquaculture platform designed to address these challenges. The system automates the sensitive phases of aquaculture — hatching and transfers — which can minimize pathogen exposure, animal stress and labor input.
