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

Tim Peake is set to control a robot rover while orbiting the Earth from space in a pioneering experiment at midday BST (7am ET) today. The British astronaut will remotely navigate the explorer through a simulated Martian landscape from the International Space Station today. The experiment, part of the ExoMars project, will take place in a hangar at Airbus Defence and Space in Stevenage. The British astronaut (pictured) will remotely navigate the'Bridget' explorer through a simulated Martian landscape from the International Space Station today. Major Peake tweeted yesterday: 'Looking forward to giving rover Bridget in Stevenage, UK, a test-drive from space.' Building on previous test and experiment campaigns, the European Space Agency, UK Space Agency and Airbus Defence and Space UK are working together to investigate distributed control of robots in a simulated planetary environment.

When Cheetah Mobile CEO Sheng Fu went to the US for the first time five years ago, he asked himself, "Why is that Chinese companies work so hard but the most important inventions and new technologies come out of America?" He concluded that the difference between China and the US is that Americans think bigger and dream bigger. The global service robotics market is set to boom, and the second half of 2015 should usher the first wave of these new helpers. Here are seven devices leading the charge. This week in Beijing, Fu announced his company is going to launch itself into AI and deep learning, create a dual headquarters in Beijing and Silicon Valley, and release robots for consumers on a global scale. No one is going to accuse Fu of not thinking big enough.

The Dial is being touted as a "voice-first" device with its own virtual assistant, called AneedA. Like Siri, Cortana and Alexa, the idea is that you can ask for information and execute tasks while your hands are full. How AneedA compares to those alternatives is, for now, a mystery. Three says it has the ability "to learn and tailor responses to each consumer" and "make traditional mobile search irrelevant." Big claims, which we're skeptical of given the performance of its previous wearable, the Puls.

Software major Infosys has developed a knowledge-based artificial intelligence (AI) platform to drive automation and innovation for its global clients. "The platform Mana brings machine learning with knowledge of an organisation to drive automation and innovation for enabling businesses reinvent their (computing) systems," the company said in a statement on Friday from San Francisco. Using the platform, the Indian bellwether improved productivity of a unspecified company with a fleet of field engineers by 50 percent by utilising its self-learning capabilities. "The platform enabled a global telecom firm to reduce 80 percent of its agents' entry effort by automating order validation and removing need for corrective processes," the statement asserted. Elaborating on multiple benefits of Mana, Infosys chief executive Vishal Sikka said, "We can automate the repetitive, mechanisable tasks; we can capture the knowledge and know-how across people and long-lived systems and bring this knowledge back inside the systems to drive more value; and in doing these things we can free people to put all of our creativity, passion, and imagination into thinking about the bigger opportunities ahead of us."

BT is about to hike prices for millions of households, and other companies are likely to follow. Prices across its broadband, phone and TV packages will be hiked up from this summer, the company has announced. It has put up costs substantially in recent years, and each hike has usually been followed by a similar move from its rivals. Landline charges will go up by £1, it said, rising 5.5 per cent to almost £19. The most popular call package will also have its price increased by about 7 per cent.

If you're looking to add artificial intelligence to a hardware project for doing things like sensing objects in an enviroment or understand voice commands, Movidius' new Fathom USB stick might be just the thing. The company is known for its Myriad 2 deep learning chip that allows DJI drones to avoid obstacles. The Fathom is essentially a portable version of the chip that can be plugged into the USB 3.0 port of Linux-based devices to run fully-trained neural networks while consuming very little power. Our biggest ever edition of TNW Conference is fast approaching! It's compatible with Caffe and TensorFlow frameworks and is capable of 150 gigaFLOPS (150 billion floating-operations per second). That means developers can use it to do things like enable robots to understand natural human speech and recognize faces, and teach drones to navigate indoors and outdoors by themselves – all without the need to connect to the cloud.

The following interview is one of many included in the report. As part of our ongoing series of interviews surveying the frontiers of machine intelligence, I recently interviewed Brendan Frey. Frey is a co-founder of Deep Genomics, a professor at the University of Toronto and a co-founder of its Machine Learning Group, a senior fellow of the Neural Computation program at the Canadian Institute for Advanced Research, and a fellow of the Royal Society of Canada. His work focuses on using machine learning to understand the genome and to realize new possibilities in genomic medicine. Brendan Frey: I completed my Ph.D. with Geoff Hinton in 1997.

Last December, Tesla CEO Elon Musk teamed up with Y Combinator president Sam Altman and former Google Brain Team scientist Ilya Sutskever to launch OpenAI, a 1 billion non-profit organization dedicated to furthering our understanding of artificial intelligence with a promise to share its research openly with the world. Today, it's taken its first step in that direction by launching a free toolkit for developers to build and train their own AI bots with games and algorithmic challenges. Some of the biggest names in tech are coming to TNW Conference in Amsterdam this May. The OpenAI Gym, currently in beta, includes environments to simulate situations for your AI to learn from, as well as a site to compare and reproduce results. The tools are designed for use with Reinforcement Learning (RL), one of the technologies used to develop Google's AlphaGo AI that defeated Go world champion Lee Se-Dol recently. RL works on the principle that a bot will receive a reward every time it completes an action successfully – similar to how you might train a dog.

Here's the tech news you need to know this Friday. The employees were part of the account-management and sales teams within the company's "publisher ad-tech group." It was a huge win across the board, and the stock increased 12% in after-hours trading. The company claims it is "curing" cancer. The stock soared more than 15% after-hours, but settled at about 8%.
