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

Choosing the perfect picture caption can be a daunting task. Knowing whether to point out certain details or add a humorous tone can be perplexing - but now there is a bot that can figure it out for you. Now, Microsoft hopes its AI will be able to do the job for you. Simply choose an image you'd like CaptionBot to analyze, upload it and the bot creates a description that seems to be pretty accurate -- in just a few seconds. CaptionBot uses natural language and computer vision to analyze pictures and write a descriptive caption -- and it will even add an appropriate emoji. The technology can decipher gender, distinguish celebrities, determine facial expressions and uses emojis to give its description more character.

Hunting submarines is dull, dangerous work. It's an elaborate game of sonar-fueled cat-and-mouse in vast stretches of open water, where the stakes are "finding foreign nations' seaborne nuclear weapons," or finding the foreign subs looking for our own seaborne nukes. DARPA, the Pentagon's future-war focused agency, wants to make it easier to find submarines, and they're enlisting robots to do it. The A is short for "Anti-submarine warfare", or ASW, and the rest of the name is ASW Continuous Trail Unmanned Vessel. The ship hit water in the middle of February, looking like nothing so much as a sparse gray Battleship piece.

According to the United Nations (UN), more than 12 million people--including 5.6 million children--have fled Syria to escape the horrors of the country's ongoing civil war and invasion by ISIS. Worldwide, the UN reports an unprecedented 59.5 million people are displaced by crisis. The flow of refugees toward Europe from Syria and other war-torn nations has caused the continent's greatest refugee crisis since World War II. Finland-based Lucify, which creates interactive data visualizations to help organizations analyze and communicate important data, recently tackled the refugee migration to Europe. Using UN data from 2012 through December 2015, its interactive map offers a time-lapse view of refugee migration and country-by-country statistics.

So he and his business partner, Dan Roth, decided to create a program that would help lawyers manage electronic documents for litigation. Their idea led them to purchase an e-discovery application. By 2000, Leib and his partner launched their own creation, Discovery Cracker. "We saw a gap in the marketplace," Leib says. Lawyers need tools to keep up with it." Instead of wading through piles of paper, lawyers now deal with terabytes of data and hundreds of thousands of documents. E-discovery, legal research and document review are more sophisticated due to the abundance of data. So while working as chief strategy officer at kCura in Chicago, Leib saw a need again in the market. "For years, lawyers have been stuck with antiquated tools that focus primarily … on Boolean search. Better tools are needed to truly understand data." "What is the future of the industry?

Like self-driving cars, drones are often misperceived by the American public. The most common concerns with drones relate to safety, privacy, and security, and we have already seen early regulatory responses from state lawmakers as well as the FAA. Despite increased regulation, Lisa Ellman, partner and co-chair of global UAS practice at Hogan Lovells, said, "Drone fever is here and drones are here to stay, whether or not we have the policy to enable their use." The solution she proposes is "polivation," bringing policymakers together with innovators to ensure policy promotes innovation. This is especially important since innovations such as drones are redefining what qualifies as aircraft.

DARPA today announced the newest of its Grand Challenges, one designed to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum. The agency's Spectrum Collaboration Challenge (SC2) will reward teams for developing smart systems that collaboratively, rather than competitively, adapt in real time to today's fast-changing, congested spectrum environment--redefining the conventional spectrum management roles of humans and machines in order to maximize the flow of radio frequency (RF) signals. DARPA officials unveiled the new Challenge before some 8000 engineers and communications professionals gathered in Las Vegas at the International Wireless Communications Expo (IWCE). The primary goal of SC2 is to imbue radios with advanced machine-learning capabilities so they can collectively develop strategies that optimize use of the wireless spectrum in ways not possible with today's intrinsically inefficient approach of pre-allocating exclusive access to designated frequencies. The challenge is expected to both take advantage of recent significant progress in the fields of artificial intelligence and machine learning and also spur new developments in those research domains, with potential applications in other fields where collaborative decision-making is critical.

Robotic systems and unmanned vehicles are playing an ever-growing role in the US military - but don't expect to see Terminator-style droids striding across the battlefield just yet. A top Pentagon official on Wednesday gave a tantalizing peek into several projects that not long ago were the stuff of science fiction, including missile-dodging satellites, self-flying F-16 fighters and robot naval fleets. Though the Pentagon is not planning to build devices that can kill without human input, Deputy Secretary of Defense Robert Work hinted that could change if enemies with fewer qualms create such machines. 'We might be going up against a competitor that is more willing to delegate authority to machines than we are, and as that competition unfolds we will have to make decisions on how we best can compete,' he said. Work, who helps lead Pentagon efforts to ensure the US military keeps its technological edge, described several initiatives, including one dubbed'Loyal Wingman' that would see the Air Force convert an F-16 warplane into a semi-autonomous and unmanned fighter that flies alongside a manned F-35 jet.

Since it was founded in 1975 by Bill Gates and Paul Allen, Microsoft has been a key player in just about every major advance in the use of computers, at home and in business. Just as it anticipated the rise of the personal computer, the graphical operating system and the internet, it wasn't taken by surprise by the dawn of the big data era. It might not always be the principle source of innovation, but it has always excelled at bringing innovation to the masses, and packaging it into a user-friendly product (even though many would argue against this). It has caused controversy along the way, though, and at one time was called an "abusive monopoly" by the US Department of Justice, over its packaging of Internet Explorer with Windows operating systems. And in 2004 it was fined over 600m by the European Union following anti-trust action.
