You may consider yourself an awesome drone pilot, able to fly skillfully at breakneck speed while dodging hazardous obstacles with a few nimble finger movements, but how would you deal with a steamed up eagle, or a chimp with a stick? Filming a historical reenactment at a recent festival in the Lipetsk region in central Russia, some poor drone pilot clearly got a little too close to the action. Watch carefully and you can see the spear-wielding guy on the ground, in full period costume, launch his weapon skyward. We have to say, it was an impressive throw, scoring as it did a perfect hit on the flying machine, sending it crashing to the ground. The video comes courtesy of Russia Today, though the news site offers few details of the reenactment event, or, more importantly, the drone calamity.

Drones have emerged in recent years as one of the hottest modern technologies. They're used for purposes as varied as monitoring crop health and tracking construction projects, endangered animals and missing persons. A reenactor at Rusborg in Lipetsk, Russia, threw a spear at a drone filming the festival devoted to the Middle Ages, causing the quadcopter to tumble to the ground. Pavel Semyonov, an organizer of the event, later explained on social media that at the time of the drone crash, participants were full of adrenaline because of a nearby weapons contest. The man who caused the drone to crash apologized for the incident and compensated the drone owner for the damaged property, according to Semyonov and the company shooting the video.

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

According to The Information, one of the last remaining members of Siri's original team, Darren Haas, has quit Apple Inc. (NASDAQ:AAPL) for General Electric (GE). His move comes only a few weeks after Steve D'Aurora resigned from his position at Apple to join GE. Both of the former Apple employees are reportedly working on a similar cloud service platform at GE. The primary reason behind the departures seems to be the political infighting within Apple's engineering team. These clashes ensued after the tech giant decided to extend the software platform built by Siri's team, to its other Internet services such as iTunes and iCloud.

It's a phrase likely to strike fear and dread into the heart of most gamers, and indeed most moviegoers. All of these classic, hugely acclaimed video games have been thrust onto the big screen (or the straight-to-DVD shelves) by people whose knowledge of the source materials seems to have been passing at best. The results have been ... horrible. Assassin's Creed, we are being told, is a different story. Produced by Ubisoft, the company that developed and published the bestselling games, it has actual star actors (Michael Fassbender, Marion Cotillard, Jeremy Irons) and a talented director in the form of Justin Kurzel, who made the award-winning Snowtown and helmed Fassbender's gritty Macbeth movie.

Along with Duncan Jones's Warcraft it's been billed as the video game movie that might just make us forget all about the cinematic crimes of Uwe Boll and his ilk, that can induce glorious amnesia for those struggling to wipe clean memories of Prince of Persia, Hitman or Lara Croft Tomb Raider: The Cradle of Life. The omens so far are good. Assassin's Creed comes from the team behind last year's blistering new take on Macbeth, with director Justin Kurzel bringing back his stars Michael Fassbender (also a hands-on producer) and Marion Cotillard. Here are five takeaways from the first trailer for the film. How strange that the cute copine from France's hit Taxi comedies has developed into one of the most sublime screen beauties of modern Hollywood.

Prostate cancer is the most common cancer in men in the UK, with more than 40,000 new cases diagnosed every year. But help in beating this form of life-threatening disease is coming in an usual form - from robots.

Artificial intelligence (AI) is something of a buzz-phrase across the tech industry these days - but Microsoft's Dave Coplin says that it will come to have a profound impact on society as we know it. In his words, AI "will change everything". Coplin, the company's chief envisioning officer in the UK, was speaking a few days ago at an AI conference in London, where he described it as "the most important technology that anybody on the planet is working on today." "This technology will change how we relate to technology," he said. "It will change how we relate to each other. I would argue that it will even change how we perceive what it means to be human."

The New York Times has a lead article on collapsing US merger deals in 2016 so far. While last year set a record for the amount of money spent on corporate mergers -- 4.7 trillion -- this year is so far setting a very different record: the dollar amount of deals that have come undone, the famous paper writes. Since the beginning of January, 400 billion worth of corporate mergers have been withdrawn in the United States, almost three times the previous record for the same period, set in 2007, according to Dealogic, which analyzes such data. In the same paper, reporter John Markoff writes that the Pentagon is turning to Silicon Valley for the edge in Artificial Intelligence. On Wednesday, Secretary of Defense Ashton B. Carter made his fourth trip to the tech industry's heartland since being named to his post last year.
