Unmanned 'Terminator' Robots Kill Jellyfish

First time accepted submitter starr802 writes "Scientists from the Korea Advanced Institute of Science and Technology in Daejeon, South Korea, have developed a 'jellyfish terminator' robot set out to detect the marine coelenterate and kill it. Scientists started developing the robots three years ago after South Korea experienced jellyfish attacks along its southwest coast, where they clogged fishing nets and ate fish eggs and plankton, Discovery News reports. The Jellyfish Elimination Robotic Swarm or JEROS has two motors that let it move forward, backwards and rotate at 360 degrees." In related news, the Oskarshamn nuclear plant in southeastern Sweden was shut down recently after moon jellyfish overwhelmed the screens and filters in cooling pipes."

      Humans can still fish (although we really should limit ourselves to recreational fishing, and stick with farmed fish for food production). But modern supertrawlers don't just decimate fish populations, they catch the entire population in an area.
