What does a microbe sound like? –
- German researchers have developed a ‘nano-ear’ that detects sounds 6 orders of magnitude below the range of human hearing.
- Optically trapped gold nano-particles are used as the listening device. It can hear sounds made at bacterial level.
- There are 10 million trillion microbes (in just seabed sediments!) for every person on the planet. There are also 10 times more bacterial cells in our bodies than human cells. What would our bodies sound like if we could amplify their world?
