The tigers in India's Panna National Park will soon live in a forest that watches out for them. A wireless network of low-power radars is being developed to track everything that moves in or out of the forest. This helps keep the tigers safe from poachers, and villagers' cattle safe from the big cats. Built by Anish Arora at Ohio State University in Columbus, the work was originally designed as a way for the US government to monitor the flow of people across the country's borders. Had the US border patrol not opted to build a 1100-kilometre-long fence instead, the system could have alerted officers to people trying to cross the border with Mexico anywhere other than at official points.
