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

A UPS drone as it takes a three-mile test flight over open ocean outside of Boston. The test was one of a series of tests to show unmanned aerial vehicles can safely be used for deliveries in the United States. The drone was built by CyPhy, a Danvers, Mass.-based drone and technology company. A UPS drone took a three mile trip over open ocean outside of Salem, Mass. The test was meant to simulate delivery of urgently needed medicine from Beverly, Mass. to Children's Island, which is home to a YMCA day camp.

Many experts believe that artificial intelligence (AI) might lead to the end of the world--just not in the way that Hollywood films would have us believe. Movie plots, for example, feature robots increasing in intelligence until they take over the human race. The reality is far less dramatic, but may cause some incredible cultural shifts nonetheless. Last year, industry leaders like Elon Musk, Stephen Hawking, and Bill Gates wrote a letter to the International Joint Conference in Argentina stating that the successful adoption of AI might be one of humankind's biggest achievements--and maybe its last. They noted that AI poses unique ethical dilemmas, which--if not considered carefully--could prove more dangerous than nuclear capabilities.

Let's be honest, stupid humans are too smart sometimes for their own good and Skynet is going to happen, at least that's what Bill Gates, Stephen Hawking and Elon Musk think, but what do they know? In 2014, Stephen Hawking wrote: "Success in creating AI would be the biggest event in human history, – Unfortunately, it might also be the last, unless we learn how to avoid the risks. In the near term, world militaries are considering autonomous-weapon systems that can choose and eliminate targets." In a separate interview in the same year, he warned: "humans, limited by slow biological evolution, couldn't compete and would be superseded by A.I." In a Reddit Q&A Session in January 2015 Gates said: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don't understand why some people are not concerned."

When his daughters were young, Nader Hamda says, they were really into apps and computers. But now that they're a little older, their interest is waning. "They're not an exception," he says. According to numerous studies, young girls are moving away from computer science, not towards it. And Hamda says this is why his company, Ozobot, is now offering an educational robot called Evo.

I remember walking into that place, which always sent you through a kitchen full of good things to eat and then into a study full of several fascinating objects, including oscilloscopes, as well as a giant model of a fly that was several feet long. The place had amazing couches and beds where the students listened carefully to Fresco. During our last talk, Fresco surprised me by arguing city planning had become more important to people than flying around on flying wings and driving in curvy cars. He reminded me of a term that I first heard when I attended school at his lab. The word was "cybernetics" -- the design of machines to make better machines than those produced by human hands.

It's a truism in comedy that the hardest role is that of the straight sidekick, the bemused Abbott who, standing in for the audience, uses subtle facial expressions and clarifying questions to allow Costello's frenzy to have its full absurdist impact. This morning, Hillary Clinton revealed herself to be an excellent sidekick--one with a bit more kick than most--the sharp, funny person her friends have told us about. She was a guest on Zach Galifianakis's "Between Two Ferns," an acerbic, occasional series on the comedy Web site Funny or Die. Usually, Galifianakis, who plays a rude, clueless talk-show host, picks movie-star foils--Brad Pitt, Will Ferrell, Steve Carrell--and it's clear that the back-and-forth insults are all in good fun. Though one previous political guest was President Obama, who jabbed Galifianakis with more abuse than he received.

The current crisis of refugees has divided European countries and societies into those who welcome refugees and those who oppose taking them. In this Viewpoint, we reflect on the role of universities and of computer science in such situations. As a case study, we describe an activity taken at the TU Wien (Vienna University of Technology): when the crisis of refugees culminated in summer 2015, a group of professors and students of the Faculty of Informatics initiated computer courses for unaccompanied young refugees. This project allowed the refugees to gain computer-related knowledge, and, equally important, to make contacts with local students. Another major goal of the project was to give a clear message that refugees are welcome.
