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

By integrating scalable human judgment into your analytics solution, you can augment your lower-confidence machine learning predictions with accurate labels, and these labels can be used as additional training data to help improve your model. In this session, we'll demonstrate how to build a real-world text analytics workflow using machine learning with humans in the loop.

As machine learning - the ability of computers to learn without being explicitly programmed - gets more mainstream and involved in our lives, here is how machines learn.

A supercomputer whirs away in London, crunching complex drug chemistries into deep learning algorithms to discover new medications. A few miles away, a DeepMind neural network scans millions of images from Moorfields Eye Hospital, searching for signs of eye disease. The application casually asks if you still have that headache from yesterday and if you'd like to book a doctor's appointment for tomorrow. Of all the fields that artificial intelligence will disrupt in the coming years, healthcare may see the greatest paradigm shift. AI's influence in the industry will be deep and broad.

Windows has a feature it doesn't like to talk about. While the OS lets you scrawl notes with a stylus, log in with you face (or secure the Web) via Windows Hello, and even order Cortana to set a reminder, what it's not so eager for you to do, apparently, is use its speech recognition engine to issue commands or take voice dictation. The reason for its silence may go back 10 years, to when Microsoft product manager Shanen Boettcher demonstrated voice dictation inside Windows Vista--and flubbed it. The technology kept a low profile after that, and today, few users know you can dictate a document within Windows. If there were ever a time for Windows to try again, though, it would seem to be now, when advances in computers and artificial intelligence provide a much better foundation for the technology.

WASHINGTON – With modern technology, people can watch hurricanes churn in real time and forecasts are on-target up to seven days in advance -- but experts say some puzzling storm traits are harder to solve. Using hurricane hunter aircraft, converted military drones, weather balloons and satellites that examine cyclones under various angles, "our observations are really telling us what is happening now," said Frank Marks, director of the Hurricane Research Division at the National Oceanic and Atmospheric Administration. "And also those observations are phenomenally useful to improving our ability to predict," he told AFP. All the collected data are immediately transmitted to meteorologists and entered into computer models that produce forecasts at the National Hurricane Center in Miami, Florida. Marks describes forecasts as simply "what we think might happen," saying experts' ability to make them has "improved dramatically for the last 35 years." When he began his career in 1980, forecasts could look ahead about two days.

Machine learning and Artificial Intelligence (AI) are transforming the healthcare industry, helping improve outcomes and changing the way providers think about delivering care. As Forbes notes, machine learning capabilities are helping improve diagnostics and predict outcomes, leading to better treatment plans and better attuned personalized care. As part of the healthcare machine learning revolution, British healthcare company Healx has secured 1.5 million in Series A round investment from Amadeus Capital Partners in order to apply machine learning and advanced analytics to the battle against rare diseases. The funding will be used to identify new uses for existing drugs and improve treatment plans for rare diseases afflicting some 350 million people worldwide, according to Tech City News. Hermann Hauser, Partner and co-Founder of Amadeus Capital Partners, said, "Healx has taken advances in machine learning, data mining, and analytics and combined them with deep pharma and life sciences expertise to address a growing need in the healthcare sector. With huge pressure on R&D budgets, drug repositioning will be essential in the fight against rare diseases. With this investment, Healx will take up a leadership position in the drug repurposing sector, expected to be worth over 31 billion by 2020."

For a sci-fi fan like me, fascinated by the nature of human intelligence and the possibility of building life-like robots, it's always interesting to find a new angle on these questions. As a re-imagining of the original 1970s science fiction film set in a cowboy-themed, hyper-real adult theme park populated by robots that look and act like people, Westworld does not disappoint. Westworld challenges us to consider the difference between being human and being a robot. From the beginning of this new serialisation on HBO we are confronted with scenes of graphic human-on-robot violence.
