On the island of Santorini, Greece, a group of AIs has been facing off in an epic battle of Doom. This is VizDoom, a contest born from one man's idea: To improve the state of artificial intelligence by teaching computers the art of fragging. That simple notion then spiraled into a battle between tech giants, universities and coders. Over the past few months they've all been honing their bots (known as "agents"), building up to one, final death match. Okay, it was a lot more than one match.

Investment into the digital health market topped 4.5 billion in 2015, and we are seeing an acceleration of investment in 2016. According to StartUp Health, investment into the digital health market for the first half of 2016 reached 3.9 billion. Early-stage innovation made up more than 65% of deals, with the majority of investment capital it going into Series A rounds. As of July, patient and consumer products, which include wearables, are leading with over 960 million invested in this sector, followed by wellness at 854 million, personalized health at 524 million, big data/analytics at 406 million and workflow at 328 million. Digital health research and population health are at the bottom of the start-up health company's list, with 65 million and 55 million, respectively. It's no surprise that we are seeing digital health M&A activity coming from tech giants such as Google, Apple and IBM.

It's a problem we can all relate to: sitting in traffic and waiting for a green light. While waiting, you may have even pondered how you would try to improve traffic efficiency--surely there's got to be some way for everyone to get to work on time. But ponder no longer, because a team of engineers from Tsinghua University in China has handed the problem over to machines. The team's recent study makes use of deep reinforcement learning algorithms to optimize traffic signaling, and its promising results suggest there may be a way to arrive on time after all. Let's be clear: traffic is a complex problem to solve, and traffic control engineers have long worked on improving efficiency.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

To get a more accurate assessment of the opinion of leading researchers in the field, I turned to the Fellows of the American Association for Artificial Intelligence, a group of researchers who are recognized as having made significant, sustained contributions to the field. "In his book, Nick Bostrom has defined Superintelligence as'an intellect that is much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills.' When do you think we will achieve Superintelligence?"

Cooperation is one of the hallmarks of being human. We are extremely social compared to other species. On a regular basis, we all enter into helping others in small but important ways, whether it be letting someone out in traffic or giving a tip for good service. We do this without any guarantee of payback. Donations are made at a small personal cost but with a bigger benefit to the recipient. This form of cooperation, or donation to others, is called indirect reciprocity and helps human society to thrive.

You might not know her name, but you would probably recognise her voice because it speaks to millions of people every day. Reacting to the launch of the latest'NoPhone' - a phone replacement made of nothing but air- the lady behind the voice of Siri said she thinks people need to start putting down their phones. Susan Bennett, the voiceover actor responsible for the female voice of Siri, says'Everybody is running around taking 15 million pictures of their own face'. She said this is making their minds wander and they cannot relate to other humans. In a study published in June, mobile research firm dscout found the average person swipes, taps and pinches their display about 2,617 times a day, for a grand total of one million times per year.

Imagine a driverless vehicle capable of using a variety of emojis, honks and signs to communicate its intentions to nearby drivers and pedestrians. Drive.ai, a new entrant in the autonomous vehicle race, has begun testing a fleet of such vehicles near its home base in Mountain View, Calif. The company, staffed by researchers from Stanford University's artificial intelligence laboratory, is getting an assist from Steve Girsky, a former General Motors executive who has been named to the Drive.ai Girsky stepped down from GM's board in June after holding several posts at the automaker, including vice chairman of GM and chairman of its Adam Opel subsidiary. "We all know that the automotive industry is in the midst of a foundational shift," Girsky said in a statement.
