Reptile sleep patterns might not actually be all that different from our own. Sleep patterns thought to be used only by mammals and birds have now been discovered in a non-avian reptile, the Australian bearded dragon. Finding those patterns, slow-wave sleep and rapid eye movement (REM) sleep, in a reptile could dramatically revise scientists' models of how those sleep patterns evolved. And they may have evolved over 300 million years ago. "The status quo, until our study, was that these features of sleep only exist in mammals and in birds," Gilles Laurent, director for the Max Planck Institute for Brain Research in Frankfurt, Germany and an author of the new paper announcing the findings in the journal Science on Thursday, tells The Christian Science Monitor in a phone interview.

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

A professor at Stanford University has designed a robotic humanoid diver with articulated hands that is designed to be an underwater avatar, exploring the way a human would-- while its driver remains safely up at the surface. The robot, which measures about five feet long, uses artificial intelligence and also a haptic feedback system to provide its controller with a feel for what the robot is holding. While the front part of the submersible resembles a human, the back part features computers, batteries, and thrusters. The machine, called OceanOne, was designed by Stanford computer science professor Oussama Khatib, who researches autonomous robots. "OceanOne is aimed at bringing a new capability for underwater exploration," Khatib said in a video showcasing the robot's abilities, in which it manipulates objects like a red basket.

April 24 can't come soon enough for Game of Thrones fans eagerly awaiting the premiere of the hit show's sixth season. Naturally, most of us have been speculating wildly about the fate of our favorite characters for the past year, but now there's a clever app to help you withthat. The project, A Song of Ice and Data, was developed by a group of students of a JavaScript course at the Technical University of Munich. Our biggest ever edition of TNW Conference is fast approaching! It looks at 24 features of each character, the list of which includes attributes like their age, the House they belong to, whether they're married and how popular they are based on how many wiki pages link to them.

The robotic geodesic sphere seen inching along Hampstead road in London. Cities like London can often feel like urban jungles with scarce amounts of green spaces. But researchers from the Interactive Architecture Lab at University College London are exploring a future scenario where "cybernetic lifeforms" that are "half garden and half machine" roam our urban cityscapes, co-existing alongside us. Hortum machina B is a robotic geodesic sphere covered in plants. The exoskeleton structure contains twelve garden modules, each of which is planted with native British species.

A humanoid robotic diver has been developed that scientists and archeologists hope will open up a new realm of deep sea exploration. OceanOne, created by researchers at Stanford University, combines artificial intelligence with human-controlled haptic feedback systems to carry out underwater tasks too dangerous for human divers. Guided by a team of deep-sea archeologists, OceanOne has already been used to investigate the shipwreck of La Lune, the flagship vessel of King Louis XIV that sank in 1664 off the southern coast of France. "OceanOne will be your avatar," said Oussama Khatib, a professor of computer science at Stanford. "The intent here is to have a human diving virtually, to put the human out of harm's way.

Effective data governance consists of protocols, practices, and the people necessary for implementation to ensure trustworthy, consistent data. Its yields include regulatory compliance, improved data quality, and data's increased valuation as a monetary asset that organizations can bank on. Nonetheless, these aspects of governance would be impossible without what is arguably its most important component: the common terminologies and definitions that are sustainable throughout an entire organization, and which comprise the foundation for the aforementioned policy and governance outcomes. When intrinsically related to the technologies used to implement governance protocols, terminology systems (containing vocabularies and taxonomies) can unify terms and definitions at a granular level. The result is a greatly increased ability to tackle the most pervasive challenges associated with big data governance including recurring issues with unstructured and semi-structured data, integration efforts (such as mergers and acquisitions), and regulatory compliance.

Tempting as it is to lay as much blame as possible at the feet of Philip Green – a man whose 63rd birthday cake involved an edible version of himself, topless, in bed with his chihuahua, silk sheets recreated in sugar paste, gold candles fringing the mattress like a flaming cage – the decline of British Home Stores was not entirely his fault. Like Austin Reed, the high-street tailor that went into administration the day after BHS, this was a business that collapsed in large part because it failed to be flexible in a changing marketplace. Both came to rely on the patronage of people who, either through a lack of access or an abundance of ethics, opted to shop physically rather than digitally. But as discussions on Twitter over what you'll miss about BHS (mostly: somewhere to go to the loo) also indicate, unless your shop serves a need that cannot be met online, it will now struggle to survive. Even Argos, whose current raison d'être is to trump Amazon by letting you get your mitts on a cheap toaster the same day, has seen a 36% year-on-year drop in profits. This its chief executive credits to "a continuation of the challenges we saw towards the back of last year with high street footfall and the move online".

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.
