Physicists uncover rotating crystals with lifelike properties
Rapporteret af AI
A team of physicists has discovered unusual rotating crystals made of spinning particles that exhibit behaviors resembling living matter, such as twisting instead of stretching and self-reassembly after breaking. These materials, governed by transverse interactions, challenge conventional crystal growth rules. The findings, published in the Proceedings of the National Academy of Sciences, suggest potential applications in technology and biology.
