It was hailed as the most significant test of machine intelligence since Deep Blue defeated Garry Kasparov in chess nearly 20 years ago. Google's AlphaGo has won two of the first three games against grandmaster Lee Sedol in a Go tournament, showing the dramatic extent to which AI has improved over the years. That fateful day when machines finally become smarter than humans has never appeared closer--yet we seem no closer in grasping the implications of this epochal event. Late last year, SpaceX co-founder Elon Musk warned that AI could take over the world, sparking a flurry of commentary both in condemnation and support. For such a monumental future event, there's a startling amount of disagreement about whether or not it'll even happen, or what form it will take.

Social networking giant Facebook is using its artificial intelligence (AI) technology and resources to map the entire Earth and launch the world's most detailed population maps that will help it beam cheap internet to remote areas. To begin with, the Facebook AI team crunched 14.6 billion images of maps from across 20 countries, including India, covering 21.6 million sq kms to come up with the first detailed map of human settlement for these countries. "This is an impressive project from our team developing solar-powered planes for beaming down internet connectivity and our AI research team. Many people live in remote communities and accurate data on where people live doesn't always exist," wrote Facebook CEO Mark Zuckerberg in a latest post. The 20 countries mapped were Algeria, Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, India, Ivory Coast, Kenya, Madagascar, Mexico, Mozambique, Nigeria, South Africa, Sri Lanka, Tanzania, Turkey, Uganda, Ukraine and Uzbekistan.

Drone images accumulate much faster than they can be analyzed. Researchers have developed a new approach that combines crowdsourcing and machine learning to speed up the process. Who would win in a real-life game of "Where's Waldo," humans or computers? A recent study suggests that when speed and accuracy are critical, an approach combing both human and machine intelligence would take the prize. With drones being used to monitor everything natural disaster sites, pollution, or wildlife populations, analyzing drone images in real-time has become a critically important big data challenge. Publishing in the journal Big Data, researchers, including Stéphane Joost from EPFL, present a new approach to rapidly interpret aerial images taken by camera drones that combines human crowdsourcing and machine learning.

An anti-tank missile fires by an Iraqi CH-4 drone destroys an ISIS artillery piece, seen in footage captured by the drone's onboard, retractable sensor turret. China's armed CH-3 and CH-4 drones have recently made international news, being used by nations that range from Iraq to Nigeria. And now NORINCO, one of China's leading defense contractors, is getting in on the international drone export game, showing off a new armed drone helicopter. The Sky Saker H300, seen here in Dubai, is China's first helicopter UCAV. Being cheaper and easier to use then larger UCAVs like the Reaper and CH-4, it could become a battalion and company level UCAV for on demand air strikes.

In an unassuming two-storey Victorian town house in Bristol, the occupants are being filmed, monitored, and tracked by invisible sensors as they go about their business, 24 hours a day. What they lose in privacy could be our gain in life expectancy, if the long-term data bears out. Pivotal to the 15-million Sensor Platform for Healthcare in a Residential Environment (SPHERE) project, the house has been invisibly fitted with dozens of cameras and sensors while its occupants are asked to don wearable devices. The aim is to reveal how health is related to everyday lifestyle and living conditions over time. The smart home observes how long the occupants slouch in front of the TV as opposed to sitting or walking or exercising.

Doha, Qatar - Faced with shrinking budgets, greater competition and increasingly selective audiences, leaders of international media organisations gathering vowed to share ideas about how best to gather and present news. "We are 20 years into the digital revolution of the media," Gary Pruitt, president of the Associated Press news agency, told a gathering in Doha of around 300 journalists from across the world. "Demand for news will only grow from here, but the supply of news will also grow. Much of it will not be of very high quality." He said that "a key component to innovation at AP is to increase work and investment into media and technology startups", adding that the agency has tested drones for news gathering purposes, and has used "robot journalism" to produce reports without human intervention.

JUDY WOODRUFF: A movie thriller being released nationally today delves into the practical, legal and moral issues surrounding drone warfare. HELEN MIRREN, Actress: We need to put a Hellfire through that roof right now. JEFFREY BROWN: It's a new kind of warfare, advanced technology that tracks, identifies, and has the power to destroy enemies by remote control from thousands of miles away. HELEN MIRREN: We have two suicide vests with explosives inside that house. JEFFREY BROWN: But as the film "Eye in the Sky" asks, should it be used?

Video Friday is your weekly selection of awesome robotics videos, collected by your mysophobic Automaton bloggers. We'll also be posting a weekly calendar of upcoming robotics events for the next few months; here's what we have so far (send us your events!): Let us know if you have suggestions for next week, and enjoy today's videos. XDog is a small electric quadruped designed and built by Xing Wang, a graduate student at Shanghai University, with support from his adviser Jia Wenchuan. The robot has 12 motors (each leg has 3 DoF), and uses force sensors on each foot, IMU, and joint-angle sensors for control.

On cold, dark days it is tempting to imagine shutting yourself away until the warmer weather returns. Many animals do it by entering a state known as torpor, which reduces their bodily functions to a minimum and uses fat stores in their body for energy, but could humans ever hibernate in the same way? Vladyslav Vyazovskiy, associate professor of neuroscience at the University of Oxford has explained what torpor does to the body and how it could affect the human body in an article for The Conversation. An expert has explained what torpor - or the act of shutting the body down during hibernation - does to the body and how it could affect humans. A'therapeutic torpor' could make a manned mission to Mars more feasible.

In a world with more mobile phones than flush toilets, digital devices are now standard equipment among even the world's poorest and most remote people. Farmers in these areas are getting tools for their devices that help deliver water, nutrients, and medicine to plants as needed; test for crop diseases and malnourishment; and survey their soil for future planning. In some cases, these emerging apps are the biggest new technologies resource-poor farms have seen in hundreds of years. That is not very surprising to Rajiv "Raj" Khosla, professor of Precision Agriculture at the College of Agricultural Sciences of Colorado State University. "What we're finding is that many small-scale farmers in resource-poor environments are still farming in the 1500s. They're looking for leapfrog technologies," he said.
