To get in the mood for this one, I've put on an old favorite, a deep bass track by Dead Prez. It turns out the song's title, and main refrain--"It's Bigger Than Hip Hop"--applies to the power of music in a very literal sense as well.
The acoustical vibrations that are particularly pervasive in the heavy bass lines of hip-hop penetrate our bodies and can then be captured and stored as electricity to power implanted medical devices. Researchers out of Purdue have built a device, which they are unveiling at the IEEE MEMS conference in Paris … Read more
