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

We describe an application of machine learning to the problem of predicting preterm birth. We conduct a secondary analysis on a clinical trial dataset collected by the National In- stitute of Child Health and Human Development (NICHD) while focusing our attention on predicting different classes of preterm birth. We compare three approaches for deriving predictive models: a support vector machine (SVM) approach with linear and non-linear kernels, logistic regression with different model selection along with a model based on decision rules prescribed by physician experts for prediction of preterm birth. Our approach highlights the pre-processing methods applied to handle the inherent dynamics, noise and gaps in the data and describe techniques used to handle skewed class distributions. Empirical experiments demonstrate significant improvement in predicting preterm birth compared to past work.

Browse the business section of any bookshop and you'll find dozens of titles promising to share the secret to climbing the corporate ladder. But the day is not far off when such books will seem as quaint and outmoded as a housekeeping manual from the 1950s. One of the key workplace trends of the 21st century has been the collapse of the corporate ladder, whereby loyal employees climbed towards the higher echelons of management one promotion at a time. Cathy Benko, vice-chairman of Deloitte in San Francisco and co-author of The Corporate Lattice, says that the ladder model dates back to the industrial revolution, when successful businesses were built on economies of scale, standardisation and a strict hierarchy. "But we don't live in an industrial age, we live in a digital age. And if you look at all the shifts taking place, one [of the biggest] is the composition of the workforce, which is far more diverse in every way," she says.

Two cucumber farmers in Japan have received an unusual boost to their business after their son adapted Google's powerful artificial intelligence software to carry out the arduous task of sorting vegetables. Makoto Koike returned to his parent's cucumber farm in 2015 after working as a computer systems designer in the automobile industry. While helping out on the farm, Koike realized that one of the most time-consuming processes could be overcome through automation. Taking inspiration from Google's powerful artificial intelligence computer program AlphaGo, Koike set about designing a sorting system using a 35 Raspberry Pi 3 computer and Google's open source deep-learning platform TensorFlow. "Each cucumber has different color, shape, quality and freshness," Koike said.

The voracious reader and self-proclaimed "learning nerd" is known to plow through at least one book every week, with a heavy emphasis on business, science and mathematics. And although the summer is (almost) over, his book menu offers plenty of brain fodder for book lovers to absorb in the fall and beyond. Some of Gates' favorite tomes range from the eclectic to the informative, including an 800-page science fiction novel and a 200-page nonfiction book on how moribund Japan can regain its economic mojo. Writing on his personal blog, gatesnotes, Gates said he hoped each selection would inspire readers to "go off the beaten path." "[These] books are simply ones that I loved, made me think in new ways and kept me up reading long past when I should have gone to sleep."

Among several new trends being pushed pumped out of the Defense Department's research offices under the guise of the Third Offset strategy -- an initiative that seeks to leverage manned-unmanned teaming to counteract adversarial capabilities -- is the concept of cognitive electronic warfare. Cognitive EW seeks to leverage artificial intelligence to adapt to rapidly changing electromagnetic surroundings in the field. The Air Force Research Lab has recently released a request for information in navigation warfare research assistance from the contracting community that includes electronic attack, electronic protection and electronic support techniques for cognitive EW applications, among other similar research areas to bolster operations in environments in which communications and navigation could be degraded or disrupted. Aircraft, upon deploying for a particular mission, have a library of profiles to counter an adversary's attempt to jam its radar. However, with the proliferation and increasing proficiency of certain adversaries in this space, such as Russia, there is a growing sense of inadequacy.

Israel is planning to bolster its high-tech arsenal by deploying fully autonomous military vehicles along the country's dangerous border with Gaza. "This is the future -- the border is a very dangerous place," an Israel Defense Forces (IDF) official told FoxNews.com, citing the threat of Improvised Explosive Devices (IEDs), snipers, anti-tank missiles and terrorist tunnels. "Sending unmanned vehicles to do these patrols means that troops lives' are not at risk." Working with Israeli defense specialist Elbit Systems, IDF has equipped Ford F-350 pickup trucks with specialized remote driving technology. The trucks, dubbed Border Protector Unmanned Ground Vehicles (UGVs), are also fitted with four driving cameras and a 360-degree observation camera to help operators identify threats.

We've only ourselves to blame. That said, the gadget fan inside of me is shamelessly drawn to the meretriciousness of the idea. The general problem of the aerial selfie is a nut that's been cracked already, but we're all for more options -- and Dobby (above) from ZeroTech is one of them. Pitched as a "pocket drone," Dobby is (as you might have guessed) small, with arms that fold out when an emergency selfie opportunity presents itself. It's not a truly hands-free experience, as you'll need your phone to control it, but it's crammed with an array of smart features and we tried most of them here in Berlin.

Dubai: In keeping with the global decline the growth of assets under management (AuM), the Middle East also witnessed a sharp fall in the total AuM last year, according to a study by Boston Consulting Group (BCG). Globally, AuM stalled with marginal growth last year. The BCG report shows the global value of AuM rose just 1 per cent in 2015, to 71.4 trillion (Dh262 trillion) from 70.5 trillion in 2014, after growing 8 per cent that year, and at an average annualised rate of 5 per cent from 2008 through 2014. In contrast, the Middle East's AuM declined 10 per cent and net new flows of assets, revenue growth, and revenue margins all dipped lower in 2015. In absolute terms the region's AuM plummeted from 1.4 trillion in 2014 to 1.3 trillion in 2015.

New Delhi: While artificial intelligence is making waves globally, Cognitive Business Intelligence (BI) is the next stage of machine learning to design and analyse unstructured data, video, images and human language, say experts. According to them, we are generating data but is this data being analysed to create insights which could help in running businesses more effectively is the real concern for businesses. "This potential can be leveraged using Business Intelligence. Using BI, we can understand what really the data means," said Nikhilesh Tiwari, Co-Founder, Helical Insight, the world's first open source Business Intelligence (BI) framework. At the moment, less than 0.5 per cent of all data is ever analysed and used globally.
