Despite its widespread use, glass still holds many scientific mysteries. One of which is how glass controls heat. Researchers from Tohoku University have recently published guidelines for designing glass materials in next-generation electronic devices after identifying a key factor that governs how heat travels through silicate glass.

The patterns that make up the weaves in textiles are seemingly endless. Certain patterns produce different qualities, such as making a material better at allowing sound to travel through it. But given the vast arrangement possibilities, testing each pattern arrangement can be a never-ending process. Now, a research team has developed an AI-assisted method to sift through the pattern possibilities.

Rust usually takes months or years to form naturally, but researchers at Tohoku University found a way to speed it up dramatically. By blasting iron powder in water with ultrasound, they triggered the formation of spinel-type iron oxide nanoparticles in as little as 24 hours, no chemicals required. The technique could offer a greener route to materials used in magnets, catalysts, and biomedical applications.

New study explains why too much ultrasound slows chemical reactions

Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.

Researchers from The University of Tokyo Institute of Industrial Science find that drones may be the next generation of communication bases to monitor the ocean and seafloor because of their high-speed positioning, stability, and efficiency.
