Summary

Story summary

Researchers at the Okinawa Institute of Science and Technology (OIST) developed a virtually frictionless levitating disk that floats above rare-earth magnets without external power.
The design eliminates eddy-current damping, increasing sensitivity for small forces, including dark-matter interactions.
The researchers publish the work in Communications Physics.
The study notes potential macroscopic quantum applications.
