US-based tech firm Department 13 has shown off its anti-drone device Mesmer, which takes control of intruding drones and forces them to land. The ASX-listed firm's esky-sized device is intended for the protection of a fixed site, such as an airport, where it can use existing radar to detect intruding drones. Previous methods to deal with nuisance drones have ranged from blasting it from the sky with a shotgun, snaring it in a net, or shooting in with an anti-drone drone -- the US military has used Hellfire missiles and 30 kilowatt shipboard lasers to destroy drones. The agency warned local law enforcement of the emerging threat that drones pose. Conversely, Department 13 worked on a method that reduced the risk of any potential danger to nearby personnel or infrastructure.

This story is part of a series inspired by the subjects and speakers appearing at BBC Future's World-Changing Ideas Summit in Sydney on 15 November. Find out more about the inspiring people coming to the meeting, including: Researcher Alex Gillespie on what artificial intelligence means for us Researcher Helen Christensen on how tech can spot and treat mental health issues Alan Finkel, Australia's chief scientist, on the future of energy BBC TV presenter Michael Mosley on the science of food and health Uber's Kevin Corti on the hidden patterns of city transport Researcher and TV presenter Emma Johnston on the impact of cities on oceans Experimental architect Rachel Armstrong on interstellar travel If you believe some AI-watchers, we are racing towards the Singularity – a point at which artificial intelligence outstrips our own and machines go on to improve themselves at an exponential rate. If that happens – and it's a big if – what will become of us? In the last few years, several high-profile voices, from Stephen Hawking to Elon Musk and Bill Gates have warned that we should be more concerned about possible dangerous outcomes of supersmart AI. And they've put their money where their mouth is: Musk is among several billionaire backers of OpenAI, an orgnisation dedicated to developing AI that will benefit humanity.

An Australian man acquitted of killing a woman on a Tinder date has been asked if he is "heartless" in a controversial TV interview. New Zealand woman Warriena Wright fell to her death from Gable Tostee's balcony on Queensland's Gold Coast in 2014. Last month, Mr Tostee was found not guilty of murder or manslaughter. Australia's 60 Minutes programme paid him A$150,000 (£90,000, $115,000) for Sunday's interview, local media said. Mr Tostee and Ms Wright had met through the dating app Tinder.

The Penny Arcade Expo (Pax) is one of the biggest gaming conventions in the world, bringing together classic consoles, the latest shooters, mobile games, PCs, Macs, tabletops – and the people who love them. For the latest event in Melbourne, Pax Australia, the biggest companies in the world – including Nintendo, Microsoft and Sony – came to show off their wares, but the most interesting stuff was relegated to one corner of the exhibition hall: Pax Rising, where independent developers let you play their latest games. Australia used to have several major international studios producing games but from 2008, several mainstays shut their doors – Sega, THQ and 2K among them – due to the global financial crisis and the rising Australian dollar. What's sprung out of this collapse is a series of small innovative Australian studios, most of them with between three and 30 employees. We've had smash hits such as Fruit Ninja, Crossy Road, Flight Control and Shooty Skies sell millions of copies around the world each year – but there are many more games that fail than succeed.

It's one thing to want to protect endangered animals, but another entirely to keep track of them. Case in point: the dugong, a medium-sized marine mammal often referred to as a sea cow. Cute they may be, but spotting them in large bodies of water is easier said than done. Since marine researchers want to do so to keep tabs on population sizes, conservation status, and their important habitat areas, that poses a bit of a problem. Fortunately, this is where Dr. Amanda Hodgson of Australia's Murdoch University comes in.

An Australian man's idea to use a drone to bring a hot dog to his hot tub hit a snag when aviation authorities warned he could face fines of up to A$9,000 (about $6,970; £5,600) for breaching drone flight safety rules. The man, named by local media as "Tim", has insisted the stunt was safe but that the sky-borne sausage was "freezing" by the time it reached him.

The Queensland government has announced amended legislation that now allows the state's farmers to use drones to spray their crops. Acting Agriculture Minister Bill Byrne said the changes to the Agricultural Chemicals Distribution Control Act 1966 and the regulations that underpin it will give Queensland farmers access to the most "innovative aerial spraying technology" available. "The government is keen to give our producers all the advantages made available by advances in technology," Byrne said. "The improvements to the legislation provide Queensland producers with cost effective options for crop protection." Byrne expects the technology to be especially useful for chemical application in areas with limited access or difficult terrain, noting that where conventional equipment cannot be used, spraying from an unmanned aerial vehicle (UAV) represents a safe and effective option.

AI experts build'neural network' to help researchers search for dugongs Dugong expert Dr Amanda Hodgson estimates she has stared at more than 30,000 photographs of blue water. "It's really taxing on your eyes and it's hard to maintain concentration." The researcher from WA's Murdoch University has been scanning pictures captured by aerial drones in a search for dugongs, to work out their population, size and location. Globally dugongs are classed as "vulnerable to extinction" and are found in waters off the northern half of Australia. "There are areas where they're quite vulnerable because their habitat overlaps with coastal development."
