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

Sea Hunter has the capability to hunt stealthy foreign submarines -- China's and Russia's navies both have big submarine fleets -- and follow them for two to three months at a time. Deputy US Defense Secretary Robert Work clarified to Reuters during the event, though, that the drone doesn't have weapons. If the military decides equip it with any, Work said the decision to use them would be made by human personnel. We're guessing they'd be controlled remotely, since the ship wasn't designed to house a crew on board. The ship is slated to start its open-ocean tests this summer off the California coast.

In this series, professionals provide advice for the next U.S. president. What do you want POTUS focused on? Over fifty years ago, in March 1964, a document known as the "Triple Revolution Report" landed on the desk of your predecessor, Lyndon Johnson. That report, written by a prominent group of intellectuals that included two Nobel laureates, argued that the United States was on the brink of dramatic social and economic disruption as rapidly advancing industrial automation technology was poised to throw millions out of work. Needless to say, that dire prediction did not come to pass.

Sure, world is crying out loud that big-data's biggest problem will be resources. Demand has skyrocketed and everyone in the world is going into tailspin in meeting that demands. Companies are going frantic and overspending to hire data scientists to secure themselves from any upcoming shortfall. This is nothing but a sign that world needs our robot algorithm friends to pacify some demand and increase credibility to new paradigms. Who could forget Steve Balmer's famous quote comparing Big Data as a Machine Learning problem.

Fear of our jobs being replaced by machines dates all the way back to the invention of the cotton gin in 1793 and maybe even earlier. But as new machines, computers, and robots are developed and jobs are lost, we have learned new jobs are created: programmers, code-writers, and so on, and society adapts. However, as technology continues to advance, the artificial intelligence capabilities of some of these new "machines" make them seem more human than ever. As a lawyer, it makes you wonder: Can these new iPeople be held liable? Think about the bank teller and the fear he must have experienced when the invention of the ATM was announced, or the cashier when self-checkout was introduced.

If we are serious about long-term human presence in space, such as manned bases on the moon or Mars, we must figure out how to streamline human-robot interactions. Right now, even the most basic of robots seem to have impenetrable brains. When I bought an autonomous vacuum cleaner, one that roams the house on its own, I thought I was going to save time and be able to enjoy a book or a movie, or play longer with the kids. I ended up robot-proofing every room, making sure wires and cables are out of the way, closing doors, placing electronic signposts for the robot to follow and much more – often daily. I cannot fully understand or predict what the system will do, so I don't trust it.

PORTLAND, OREGON – The U.S. military on Thursday christened an experimental self-driving warship designed to hunt for enemy submarines, a major advance in robotic warfare at the core of America's strategy to counter Chinese and Russian naval investments. The 132-foot-long (40-meter-long) unarmed prototype, dubbed Sea Hunter, is the naval equivalent of Google's self-driving car, designed to cruise on the ocean's surface for two or three months at a time -- without a crew or anyone controlling it remotely. That kind of endurance and autonomy could make it a highly efficient submarine stalker at a fraction of the cost of the Navy's manned vessels. "This is an inflection point," Deputy U.S. Defense Secretary Robert Work said in an interview, adding he hoped such ships might find a place in the Western Pacific in as few as five years. "This is the first time we've ever had a totally robotic, trans-oceanic-capable ship."

The annual Data Science Bowl hosted by Booz Allen Hamilton and Kaggle is based on the premise that crowdsourced solutions can be used to solve some of our world's most complex problems. This year, the focus was on heart health – an issue of critical importance worldwide. In the U.S. alone, one person is diagnosed with heart disease every 43 seconds. It typically takes 20 minutes to have an MRI analyzed and a diagnosis delivered. However, this year's Bowl managed to create an algorithm that allows your doctor to receive your results and prognosis in real-time.

Today is christening day for DARPA's Sea Hunter, a full-scale prototype of an autonomous surface vessel that's designed to be able to launch from a pier and go out on its own for weeks or months at a time, for thousands of miles at a stretch. The 132-foot-long, diesel-powered vessel was built by U.S. defense contractor Leidos under DARPA's ACTUV program, a somewhat clunky nested acronym that stands for Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel. The ship, now a joint project with the U.S. Office of Naval Research, was originally conceived as a tracker of stealthy diesel-electric submarines, but it's a flexible platform. "What we've kind of realized over the course of the program is that it's a truck," program manager Scott Littlefield tells IEEE Spectrum. "It's got lots of payload capacity for a variety of different missions."

Years from now, a robotic astronaut named Val could walk across the dusty Martian terrain to greet a spaceship carrying humans ready to colonize the Red Planet. How well the robot does that job will fall to some Bay State universities, who are playing a key role in teaching Val how to be an astronaut's best friend. "What she will be able to do, hopefully, is just about everything that a suited astronaut in a planetary field could do," said Kris Ver deyen, NASA project manager for Val. "This is NASA's first foray into a bipedal motion robot, so we're basically learning the ropes as we go." Val -- short for Valkyrie -- is a 6-foot, 2-inch, 300-pound mass of metal, wires and plastic that was delivered to University of Massachusetts Lowell at 6:30 yesterday morning, along with a squad of NASA engineers, who put together the robot piece by piece.
