natural ability to glide quietly through the water, sense delicate electrical gradients and follow chemical trails,&quot; says the report, carried in next Saturday&#8217;s New Scientist. <br \/>\u00a0 <br \/>&quot;By remotely guiding the sharks&#8217; movements they hope to transform the animals into stealth spies, perhaps capable of following vessels without being spotted.&quot; <\/font><\/p>\n<p><font size=\"2\">The unusual project is being funded by the Pentagon&#8217;s Defense Advanced Research Projects Agency (Darpa), which pioneered the Internet as a platform for robust communications. <br \/>\u00a0 <br \/>Scientists involved in the scheme presented their work last week at a meeting on Ocean Sciences in Honolulu, Hawaii, according to the report. <br \/>\u00a0 <br \/>A team at Boston University have implanted electrodes into the brain of a spiny dogfish in a shallow tank. <br \/>\u00a0 <br \/>The implants, controlled by a small radio transmitter, stimulate either the right or left side of a brain area dedicated to smell, causing the fish to flick around in that direction in response to the signal. <br \/>\u00a0 <br \/>The next step will be to take this device outside the laboratory. <\/font><\/p>\n<p><font size=\"2\">Blue sharks implanted with the gadget are to be released off the coast of Florida. <br \/>\u00a0 <br \/>As radio signals will not penetrate the sea, communications with the fish will be made through US Navy acoustic towers capable of sending sonar signals to a shark up to 300 kilometres away. <br \/>\u00a0 <br \/>Other Darpa-funded researchers are working on using implants to record brain activity in sharks in order to understand which neurons are fired by scents, electrical or magnetic fields. <br \/>\u00a0 <br \/>These signals help the fish to navigate and offer the reward of food, and could thus in theory be manipulated for surveillance work. <br \/>\u00a0 <br \/>New Scientist says the Darpa work is controversial, but also points out that work with animal implants also has a potential benefit for medicine. <br \/>\u00a0 <br \/>Understanding more about the brain&#8217;s electrical signals could one day result in implants to control a prosthetic limb to overcome paralysis. <\/font><\/p>\n<p><font size=\"2\"><em>Inet-Bridge ||<\/em>\u00a0 <\/font><a href=\"http:\/\/mybroadband.co.za\/vb\/showthread.php?t=38551\" target=\"_blank\" rel=\"noopener\"><font size=\"2\">Discuss this article<\/font><\/a><font size=\"2\"> <\/font><\/p>\n<p><em><font size=\"2\"><\/font><\/em><\/p>\n<p><em \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Pentagon is funding research into neural implants with the ultimate hope of turning sharks into &#8220;stealth spies&#8221;
