Supply-chain experts see reliable data, STEM education and smarter regulation as essential for Australia to succeed in an increasingly automated world under pressure to be environmentally sustainable.
Ant colonies direct traffic flows of millions of individuals along the best routes – army ants even manage inbound and outbound lanes – but how?
Insects aren't known for having big brains, and slime moulds and fungi don't have any. So how do they solve challenges that test the ingenuity of human transport engineers?
