It may sound more like science fiction than science fact, but researchers have created bionic jellyfish by embedding microelectronics into these ubiquitous marine invertebrates with hopes to deploy them to monitor and explore the world's oceans.
A small prosthetic enabled the jellyfish to swim three times faster and more efficiently without causing any apparent stress to the animals, which have no brain, central nervous system or pain receptors, the researchers said.
The next steps will be to test ways to control where the jellyfish go and develop tiny sensors that could perform long-term measurements of ocean conditions such as temperature, salinity, acidity, oxygen levels, nutrients and microbial communities. They even envision installing miniscule cameras.
