Rewiring brains to see with sound

A new device, vOICe, that translates visual images into “soundscapes” to restore a form of sight to the blind, is turning our understanding of the senses upside down. Some long-term users of the device eventually report complete images somewhat akin to … Continue reading

Jupiter Space Sounds

A recording of Jupiter sounds (electromagnetic “voices”) by NASA-Voyager. The complex interactions of charged electromagnetic particles from the solar wind , planetary magnetosphere etc. create vibration “soundscapes”. It sounds very interesting, even scary. Jupiter is mostly composed of hydrogen and … Continue reading
