Why do dunes sing? Head into the mysterious world of sand with host Joe Hanson! Along the way we meet Dr. Melany Hunt and Dr. Nathalie Vriend who solved the longstanding mystery of why dunes sing.

Yes. Microwaves and radio waves are physically the same, i.e. both are forms of electromagnetic radiation. Some microwave rays can leak out and interfere with WiFi signals. We are basically constantly surrounded by electromagnetic...
