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

Hillary Clinton told federal agents and prosecutors that she did not recall receiving any emails that were too secretive to be handled by her private computer server and did not believe any of her devices had been hacked or compromised, according to FBI records released Friday. The former secretary of State reiterated earlier comments that she decided to use a single private email address to send personal and work correspondence as "a matter of convenience" and was not seeking to avoid having to comply with open records laws, according to an FBI summary of a three-hour interview with agents and prosecutors on July 2. The Democratic presidential nominee added that she relied on her staff -- three of her closest aides were responsible for the vast majority of her work-related correspondence -- and career diplomats to filter out secret information before it reached her unclassified email account. She pushed back when pressed by agents about specific emails containing classified material, saying she was not concerned that the information was sensitive or should have been deemed classified. During its investigation, the FBI determined that 110 emails contained material that should have been sent only on a classified system, even though they was not marked as such at the time. Another three emails included markings to indicate they contained classified information.

U.S. stocks rose Friday as investors found some positive aspects in a middling employment report. Job growth slowed in August, and traders hope that will persuade the Federal Reserve to wait before raising interest rates. Stocks started the day with big gains following the Labor Department's job report. Energy companies rose more than the rest of the market as oil prices broke out of a four-day slump. The gains were broad, but the stocks that rose the most were utilities, which would stand to benefit if interest rates remain low.

A new breed of robots could someday learn to act human without being told how to behave. These machines are able to learn both how natural and artificial systems work by simply watching them. This could mean advances in the world of robotics with machines able to predict, among other things, human behaviour, as well as imitate it. A new breed of robots could someday learn to act human without being told how to behave. The researchers put a swarm of robots under surveillance, and wanted to find out the rules which governed their movements.

Before Neil Armstrong took one giant leap on the moon, Nasa looked to a robot for help with testing the crew's spacesuits. The 1965 PDAD (Power Driven Articulated Dummy) robot simulated 35 basic human motions and used sensors to gather data on how the human body would act in pressurized suits - but it never fulfilled its mission due to a tendency to leak oil. Now, the metallic astronaut is set to be sold along with 100 other'Remarkable Rarities' from RR Auction, who has marked Nasa's reject robot with an 80,000 price tag. 'Only two of the test robot's were produced -- the other is on display and owned by the Smithsonian National Air and Space Museum,' Robert Livingston, RR Auction executive vice president, in a statement to collectSpace. 'This [robot] was purchased as surplus from the University of Maryland.' The auction will be hosted online starting September 15 and finish with a live sale at the Royal Sonesta Boston on September.

Star Wars could soon be headed to the battlefield. The Department of Defence has shown off a prototype of its'hoverbike,' a rectangular shaped quadcopter that has been named the Joint Tactical Aerial Resupply Vehicle, or JTARV. It is working with New Zealand inventors Malloy Aeronautics on the radical machine that could take troops into battle and deliver supplies. The Army Research Laboratory has shown off a prototype of its'hoverbike,' a rectangular shaped quadcopter that has been named the Joint Tactical Aerial Resupply Vehicle, or JTARV The'hoverbike' is similar to a quadcopter, using four standard helicopter style rotors, overlapped with each other. The full sized design uses a motorcycle engine and controls.

Dmitry Malioutov can't say much about what he built. As a research scientist at IBM, Malioutov spends part of his time building machine learning systems that solve difficult problems faced by IBM's corporate clients. One such program was meant for a large insurance corporation. It was a challenging assignment, requiring a sophisticated algorithm. When it came time to describe the results to his client, though, there was a wrinkle. "We couldn't explain the model to them because they didn't have the training in machine learning." In fact, it may not have helped even if they were machine learning experts. That's because the model was an artificial neural network, a program that takes in a given type of data--in this case, the insurance company's customer records--and finds patterns in them. These networks have been in practical use for over half a century, but lately they've seen a resurgence, powering breakthroughs in everything from speech recognition and language translation to Go-playing robots and self-driving cars.

Working together, the likley modified commercial drones could be good indoor scouts. There is little detail in the 1 million contract award posted yesterday. The award, from the Army, but through the Pentagon's brand-new tech-focused "Defense Innovation Unit Experimental" DIUx, is for a nine-month "prototype project in the area of Autonomous Tactical Airborne Drones." Two other salient features stand out in the little, obligatory blurb attached to the notice. The contract comes from the Naval Special Warfare Command, which mostly oversees Navy SEALs, and the contract was awarded to Shield AI.

When you think of a concrete object, you think wordlessly, and then, if you want to describe the thing you have been visualising you probably hunt about until you find the exact words that seem to fit it. When you think of something abstract you are more inclined to use words from the start, and unless you make a conscious effort to prevent it, the existing dialect will come rushing in and do the job for you, at the expense of blurring or even changing your meaning. In recent years, in my reporting, I've come to uncool conclusions. For one thing, I've begun to think that instilling public purpose into private communities is the hardest thing in the world. Last week, the University of Chicago's college dean of students riled the Internet when he dispatched a welcome letter to freshmen that declared the university to be a space safe from safe spaces.
