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

The Chinese government produces 488 million'fake' social media posts a year to distract citizens from news critical of the Communist Party, a new study has revealed. According to the study, written by Harvard University professor Gary King, the goal of the secretive army of commenters is to "distract the public and change the subject" in online discussions which paint the government in a negative light. The study is reportedly the first of its kind to show concrete evidence of the existence of the '50 Cent Party', a name which references the 50 cents each worker is thought to be paid for a post. During the study, co-authored by Stanford University's Jennifer Pan and UC San Diego's Margaret E. Roberts, machine learning techniques were used to analyse millions of social media posts, based on leaked emails and databases which detail the work of the group. The research revealed co-ordinated commenting efforts, usually timed to coincide with government announcements or patriotic public holidays.

An entire sector of the federal government is held hostage by the last century. The death spiral of the gas tax, and the other broken user-fees, demand we reform federal transportation funding, harness emerging technology, and guide the autonomous vehicle revolution. The powerful disruptive force of car sharing services like Uber and Lyft will rapidly be joined by autonomous vehicle technology. A huge part of our economy and culture--the American way of life designed around the automobile for the last century--will change. Our challenge is to use that change to solve problems rather than create new ones, and maintain and tailor our existing infrastructure for the future.

AN ALARMING app that can scan a person's face and identify who they are and what they are into has become very popular in Russia. This is the opposite of great, and represents a threat to privacy that has staggered even The Guardian newspaper, which has reported that the FindFace app is very accurate and can even be used to recognise whole crowds. It is the sort of thing that we might have expected to report alongside words like'Snowden' and'National Security Agency', but actually it's a consumer thing that draws on Vkontakte, the Russian equivalent of Facebook, to match mugs with, well, mugs. "In the short time since the launch, FindFace has amassed 500,000 users and processed nearly three million searches," said a report in The Guardian. "Some have sounded the alarm about the potentially disturbing implications. Already the app has been used by a St Petersburg photographer to snap and identify people on the city's metro, as well as by online vigilantes to uncover the social media profiles of female porn actors and harass them."

Clutter is a special challenge for robots, but new Carnegie Mellon University software is helping robots cope, whether they're beating a path across the Moon or grabbing a milk jug from the back of the refrigerator. The software not only helped a robot deal efficiently with clutter, it surprisingly revealed the robot's creativity in solving problems. "It was exploiting sort of superhuman capabilities," Siddhartha Srinivasa, associate professor of robotics, said of his lab's two-armed mobile robot, the Home Exploring Robot Butler, or HERB. "The robot's wrist has a 270-degree range, which led to behaviors we didn't expect. In one case, the robot used the crook of its arm to cradle an object to be moved.

IBM's voice-recognition AI ROSS,' powered by the Watson supercomputer, has just landed a position at New York law firm Baker & Hostetler handling the firm's bankruptcy practice.

From self-driving vehicles to social robots, artificial intelligence is evolving at a rapid pace, creating vast opportunities as well as complex challenges. Recognizing that, the White House Office of Science and Technology Policy is co-hosting four public workshops on artificial intelligence -- the first of them May 24 at the University of Washington. Subsequent events will take place in Washington, D.C.; in Pittsburgh, Pennsylvania; and in New York City. Put on by the UW School of Law and the UW Tech Policy Lab, the session will focus on legal and policy issues around artificial intelligence, or AI. Etzioni will provide an overview on the current state of artificial intelligence, followed by two panel discussions.

The National Telecommunications & Information Administration released Thursday a list of voluntary privacy best practices for commercial and non-commercial drone users, in the wake of concerns that drones could encroach on individual privacy and open a new front in the collection of personal data for commercial use. The privacy guidance, arrived at in consensus with drone organizations and companies like Amazon and Google's parent Alphabet, recommends that drone operators who collect personal data should have a privacy policy that explains what personally identifiable information they will collect, for what purpose the data is collected and if it will be shared with others, including in response to requests from law enforcement agencies. The guidelines also encourage drone operators to avoid using or sharing personal data for marketing purposes without consent of the individual. Drone operators should also not use personal data without consent for "employment eligibility, promotion, or retention; credit eligibility; or health care treatment eligibility other than when expressly permitted by and subject to the requirements of a sector-specific regulatory framework." Data collected should also not be held beyond a reasonable period, without the consent of the individual, or in exceptional circumstances, such as legal disputes or safety incidents.

The giant hedge fund, which manages 35 billion, is as much a technology company as it is a hedge fund. It uses advanced technologies to find investment opportunities, and it just hosted its annual artificial intelligence competition. One of those technological applications involves using natural-language-processing techniques to analyze the Fed minutes, such as those set for release Wednesday afternoon. "Historically, interpretations of those minutes required art, so Fed watchers pontificated and critiqued," the firm said in a note. "Now natural language processing techniques can translate those minutes into relatively objective data."

Last month, law firm Baker & Hostetler announced that it would employ IBM's artificially intelligent lawyer, Ross, to help ease its tedious workload. In a statement, the firm's chief technology officer said, "we believe that emerging technologies like cognitive computing and other forms of machine learning can help enhance the services we deliver to our clients." Ross, a system built on the back of IBM's Watson, claims to be able to interpret questions lawyers ask it, and read "through the entire body of law and returns a cited answer and topical readings from legislation, case law and secondary sources to get you up-to-speed quickly." But the first thing I noticed about Ross wasn't how many legal documents it can search at once, or how accurate it claims to be. It was the name: Ross.
