Scientists are building cyborg jellyfish to explore ocean depths

As climate change continues to warm our oceans and increase their acidity due to carbon dioxide absorption, the need for effective monitoring of marine environments has never been more critical. Traditional methods of reaching the ocean's depths can be prohibitively expensive, leaving a gap in our understanding of these vital ecosystems. In a groundbreaking project, researchers at the University of Colorado at Boulder have turned to moon jellyfish, utilizing their natural ability to navigate deep waters. By integrating microelectronic devices into these jellyfish, dubbed 'cyborg' jellyfish, the team aims to collect essential data on ocean temperature, acidity, and other significant environmental factors. The researchers are also delving into the biomechanics of jellyfish swimming, which helps enhance the design of their biohybrid creations. Their latest findings, published in the journal Physical Review Fluids, explore the water flow patterns created by these swimming jellyfish, using biodegradable particles to visualize the currents. The concept of biohybrid creatures is not new; scientists have been experimenting with cyborg insects since the 1990s. Early research included implanting electrodes into cockroach antennae, allowing researchers to control their movements for potential applications in search-and-rescue missions. In 2015, a study at Texas A&M demonstrated that implanting electrodes into a cockroach's ganglion could effectively guide the insects, achieving a success rate of 60% in steering them using remote-controlled shocks. As this research progresses, the hope is that these cyborg jellyfish will provide unprecedented insights into the changing conditions of our oceans, paving the way for future innovations in marine exploration.
