Scientists have long known that common emotions can trigger sensations in our bodies — whether it’s butterflies in the stomach (anxiety) or hot cheeks (shame). And now a new study suggests that we all have the same bodily sensations associated with our feelings regardless of culture or language — because the mind-body connection is biological, and is linked to our very drive for survival.
A group of researchers at the University of Tokyo use sound waves to levitate various objects. Tiny little beads lift into the air and glide around in perfect formation. An iron screw spins gently in space. Pieces of plastic, broken match heads, and even droplets of water all defy gravity, all thanks to the precise application of ultrasonic sound waves.
