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

NHS eye hospital Moorfields has announced it is working with DeepMind -- an artificial intelligence research lab acquired by Google in 2014 for a reported 400 million -- in a bid to identify people who are likely to lose their sight as a result of an eye disease. Through the medical research partnership, Moorfields will investigate whether DeepMind's AI technology can be used to help spot early signs of eye conditions that human eye care experts might miss. In order to determine whether DeepMind's AI technology is useful for diagnosing eye conditions, Moorfields is applying the company's algorithms to one million anonymous OCT (Optical Coherence Tomography) scans. The aim is to determine whether the algorithms can learn to spot early signs of age-related macular degeneration and sight loss that occurs as a result of diabetes. Mustafa Suleyman, Google DeepMind cofounder and head of DeepMind Health, told Business Insider that he wants DeepMind's AI to understand the structure and nature of eye scans "well enough to be able to try to predict in advance which ones indicate that a patient may be at risk to a particular kind of eye disease." The algorithms that DeepMind builds are known as machine learning algorithms because they have the ability to learn through training without being explicitly programmed.

When the Raspberry Pi computer was first launched in 2012 to promote the teaching of computer science, its creators probably didn't imagine the 35 device would one day take on a professional fighter pilot in a dogfight--and win. But that is exactly what a doctoral graduate at the University of Cincinnati set out to do when he built a Pi-powered artificial intelligence pilot. The AI, dubbed ALPHA, went up against retired United States Air Force Colonel Gene Lee in a series of simulated battles, beating Lee in every single engagement. Lee described ALPHA as "the most aggressive, responsive, dynamic and credible AI I've seen to date." ALPHA has gone on to defeat other expert fighter pilots in what is being hailed as a significant breakthrough in unmanned flight.

For more than 40 years, no single director has more defined what we think of when we think of the movies than Steven Spielberg. To date, his feature films have grossed 4.3 billion in North America and 9.2 billion worldwide, more than any other filmmaker in history by a comfortable margin. His movies have been nominated for 128 Academy Awards and won 32, and Spielberg personally has been nominated for 16 Oscars, winning three (Best Director for Saving Private Ryan, and Best Director and Best Picture for Schindler's List). And if that's not enough, Spielberg has also presided over at least two of the most transformative changes of the last 50 years in the movie industry: the creation of the summer blockbuster (with Jaws) and the proliferation of computer-generated imagery in visual effects (with Jurassic Park). To be sure, Spielberg has not done any of this alone. With George Lucas and Harrison Ford, he helped create Indiana Jones. With Tom Hanks, he established an ongoing creative partnership (and lifelong friendship). His longtime producer Kathleen Kennedy -- the woman currently shepherding the revival of Star Wars -- got her start as Spielberg's secretary. Just about every one of his films have been tightly edited by Michael Kahn and majestically scored by John Williams. And he's collaborated with a small stable of top-flight screenwriters, including David Koepp, Richard Curtis, Eric Roth, Lawrence Kasdan, Steven Zaillian, Tom Stoppard, Tony Kushner, Joel and Ethan Coen, and, on his newest film The BFG, Melissa Mathison. When we go to a Spielberg movie, we know we will see a film made with consummate craft and exhilarating visual style -- few directors know better how to harness the tools of pure cinema. But I would argue the artistic constant that has informed Spielberg's career and success more than any other has been his seemingly limitless capacity for empathy. "Movies are like a machine that generates empathy," the late Roger Ebert once said. "It lets you understand a bit more about different hopes, aspirations, dreams and fears. It helps us to identify with the people who are sharing this journey with us." Ebert might as well have been describing Spielberg's entire career, and I know that because, like a crazy person, I screened all 29 of Spielberg's theatrical feature films in chronological order, and then ranked them from worst to best. I also skipped 1983's Twilight Zone: The Movie, since Spielberg directed just one of five segments in the film.) By my count, only three of Spielberg's movies are irredeemably bad.

Globalization, an ever-growing corpus of regulations and increasing business complexity all conspire to make it challenging to understand, implement and prove regulatory compliance. With the Compliance Dictionary, Unified Compliance Framework (UCF) is aiming to change that. For instance, 'Personally Identifiable Information' (PII) was defined legally in a 2007 memorandum from the Executive Office of the President, Office of Management and Budget (OMB) and later adopted in the National Institute of Standards and Technology (NIST) Guide to Protecting the Confidentiality of Personally Identifiable Information (SP 800-122). But other regulatory and standards bodies frequently refer to PII as'identifying information,' 'personal information' or'private information.' In the European Union, EU directive 95/46/EC refers to it as'personal data.'

One million anonymised eye scans from Moorfields Eye Hospital will be used to train an artificial intelligence (AI) system from Google. Machine learning algorithms will scour the images for signs of diseases such as macular degeneration and diabetes-related sight loss. Moorfields is teaming up with Google's AI division DeepMind during the scheme. Previously, DeepMind faced criticism over a little-known data sharing agreement with three London hospitals. An agreement to share patient data from the Royal Free, Barnet and Chase Farm hospitals over the past five years and continuing until 2017 was revealed by the New Scientist in May. In that case, Google said it was analysing kidney data in the hope of developing an app for medical staff.

WASHINGTON – Coalition forces fighting the Islamic State group in northern Syria destroyed one of their own combat drones Tuesday after the unmanned aircraft crashed, the U.S. Air Force said. The MQ-9 Reaper -- a type of armed drone -- crashed while flying a combat mission after remote pilots lost "positive control" of the aircraft, the Air Force said in a statement. "The remotely piloted aircraft crash was not due to enemy fire. There are no reports of civilian injuries or damage to civilian property at the crash site," the statement reads. Coalition craft then destroyed what was left of the drone.

A U.S. military drone crashed in northern Syria while carrying out a combat mission against ISIS, the Air Force said Tuesday. According to a statement, the MQ-9 Reaper drone was not brought down by enemy fire and there were no reports of civilian injuries or damage in the crash. The statement added that aircraft of the U.S.-led coalition destroyed the crashed drone before it could fall into ISIS hands. An investigation will be conducted to determin the exact cause of the crash. The Obama administration has often used unmanned aircraft to target leaders of terror groups.

For more than 30 years, Gibbs has advised on and developed product and service marketing for many businesses and he has consulted, lectured, and authored numerous articles and books. So the UK has just given itself a national headache. Whether you think the Brexit was the right decision or a dangerous and unmitigated screw-up (as I do), the consequences of the referendum will be non-trivial and take years to complete. But the mechanics of the UK exiting the European Union aside, the question of how people now feel about the Brexit is interesting. Are they awash in jubilation or has buyer's remorse set in? An intriguing post by MonkeyLearn attempts to answer this question by analyzing tweets and, as a bonus, provides tools that you might well find useful for similar exercises.

'The two most aggressive military forces in the world have added a new frontier in their immense ability to deal death and destruction. In the same week, an Israeli firm launched the first-ever torpedo from an unmanned sea vessel while a U.S. artificially intelligent fighter pilot easily won combat simulations against human pilots. These achievements are a testament to the sad reality that military interests are often the first to take advantage of wondrous advancements such as AI, just as nuclear physics and other technologies were hijacked for more efficient methods of killing.'
