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

Tekstum provides real-time scientific analysis of the opinions and feelings that readers are expressing online. Using a state-of-the-art algorithm built with big data and artificial intelligence, the company promises to revolutionise how publishers market, and how customers search for and buy books, by synthesising, analysing and visualising readers' moment-to-moment emotions and experiences. Spanish founder and CEO Marc Santandreu worked for international publishing companies such as Author Solutions and Regió7. Lauren Romeo (PhD in Computational Linguistics) is the Lead Scientist, pioneering the Natural Language Processing research and development of the engine, while Juanjo Fernandez is the engineer responsible for the development of the software. Every year the number of new books in the market grows exponentially, generating huge amounts of data at ever-faster rates.

When you think of leaders in artificial intelligence, Netflix (NASDAQ:NFLX) doesn't usually jump to the top of the list. But the streaming video service's VP of Product Innovation Carlos Uribe-Gomez and Chief Product Officer Neil Hunt published a paper that says some of its AI algorithms save Netflix 1 billion each year. In their paper, the two Netflix execs detail how the company's recommendation engine impacts its churn rate. Netflix no longer reports its churn rate, but the paper notes that Netflix's "retention rates are already high enough that it takes a very meaningful improvement to make a retention difference of even 0.1%." Let's dive into how the recommendation engine saves Netflix money -- and what the return on investment looks like.

In the midst of a continuing refugee crisis across much of the globe, June 20 marks World Refugee Day, an occasion that seeks to raise awareness for the plight of refugees across the world. And thanks to a partnership between Blippar, the augmented reality and artificial intelligence company, and UN refugee agency UNHCR, that awareness is going digital. Currently, the Blippar app allows people to "blipp," or scan objects they want to learn more about, thereby accessing informational or entertaining content about the world around them. As part of the new campaign, Blippar is asking users to show their support for refugees by blipping their hands. This scan of support translates into an instant signature on the UNHCR #WithRefugees petition, which requests that national governments act with solidarity and shared responsibility when it comes to the migrant crisis.

HBO's trailer for'Westworld' trailer doesn't want you to question your own reality. HBO's trailer for'Westworld' trailer doesn't want you to question your own reality. First rule of building an adult theme park where the elite can live among an android population pretending it's the Wild, Wild West: Install an off button. HBO's long-awaited new drama just dropped a trailer showcasing the actual plot of its android series based off the 1973 Michael Crichton movie starring Yul Brynner. The 2016 version is spearheaded by J.J. Abrams, Jonathan Nolan and Lisa Joy.

There are countless internet quizzes that helps sort you into Hogwarts houses depending on your personality, but nothing comes quite close to this: an actual sorting hat powered by IBM Watson. The hat, created by IBM engineer Ryan Anderson, started off as a fun project for him and his two daughters to help expose the girls to STEM while bridging it with their interests in the Harry Potter series. The hat uses Watson's Natural Language Classifier and Speech to Text to let the wearer simply talk to the hat, then be sorted according to what he or she says. Anderson coded the hat to pick up on words that fit the characteristics of each Hogwarts house, with brainy and cleverness going right into Ravenclaw's territory and honesty a recognized Hufflepuff attribute. His daughter helped by adding lines of established "ground truths" for each of the four houses, with Watson using deep learning to figure out more attributes and expanding known qualities of each house every time the hat is worn.

Olli, a 3D printed, self-driving minibus, to hit the road in US A new maker of self-driving vehicles burst onto the scene Thursday in partnership with IBM's supercomputer platform Watson, and it's ready to roll right now. The vehicle -- a 3D-printed minibus called "Olli" capable of carrying 12 people -- was unveiled by Arizona-based startup Local Motors outside the US capital city Washington. Napster's improbable journey This week the Rhapsody music service announced that it will retire the Rhapsody name and re-brand its service (and the company) under the Napster brand. The Napster name has endured a long journey in the 17 years since Shawn Fanning first created the service in early 1999. I thought it might be helpful to put together a short history tracing that path.

I heard you mention a way to stop robocalls on your national radio show. I was unable to write it down at the time. I am so tired of these calls! A. The service I spoke of is called Nomorobo. It lets the phone ring once, and then it identifies the caller. If the caller is a robot telemarketer, it automatically hangs up for you.

AI carries profound questions for the future. Many dramatic predictions about it have not yet proven out, but it seems clear that big change is coming and accelerating, and could profoundly change the human experience. One scenario is depicted in the movie Her, about a human-like, voice-only operating system -- with its startling final plot twist. This year Microsoft withdrew a new AI-based chatbot (talk robot) named Tay after one day, because she had "learned" abhorrent views through her online conversations. People also worry about (or hope for) the evolution of trans-human technology like enhanced eyesight (watch for author Brett King's upcoming book, Augmented).
