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

Mars, our neighboring planet, has captured people's imaginations for centuries. In the last 50 years, orbiters and rovers have been exploring its environment, its atmosphere, and its geology, sending back a wealth of information. The more we learn about the Red Planet, the more we want to send human explorers there. Is now the time to go? The National Aeronautics and Space Administration's priority is Mars, but there are conflicting opinions among US decision makers about the country's space-travel priorities.

A new signal has been found deep in space that could come from aliens. The community of astronomers and scientists who scan the skies with telescopes in an attempt to find extraterrestrial life is abuzz with excitement over a "strong signal" detected deep in space that could come from an alien civilisation. But some scientists have cautioned people not to get quite so excited – at least yet. The evidence remains preliminary and more work will need to be done to establish whether it is not just a mistake, let alone wheat it's actually a message from aliens. The message appeared to have come from a nearby star, HD164595, in the constellation Hercules.

Hundreds of billions of dollars lies dormant in data. From retailers and healthcare providers to government agencies, untapped data has the ability to generate savings, drive efficiencies, and make entirely new paradigm-changing discoveries. And while companies almost universally accept that data is the new gold, they still haven't managed to consistently put it to use and unlock its value. To do so requires the ability to not only crunch data and build algorithms, but the ability to deeply understand its significance and convey it to the decision-makers. And as business problems become increasingly complex and the volumes of data explode, it makes sense that the industry first-movers are turning to artificial intelligence (AI) to tackle the analytics problem head-on.

WASHINGTON – Federal aviation officials estimate there will be 600,000 commercial drone aircraft operating in the U.S. within the year as the result of new safety rules that opened the skies to them on Monday. Michael Huerta, head of the Federal Aviation Administration, said at a news conference that the rules governing the operation of small commercial drones are designed to protect safety without stifling innovation. Commercial operators initially complained that the new rules would be too rigid. The agency responded by creating a system to grant exemptions to the rules for companies that show they can operate safely.

Look alive, stateside drone pilots: the Federal Aviation Administration's initial set of operational rules for commercial UAV flights officially goes into effect today. Those rules were finalized back in June and govern any unmanned UAV under 55 pounds that is flown for "non-hobbyist purposes." As a quick refresher, drones that meet those qualifications can only operate during daylight hours (until dusk if the drone is equipped with warning lights) and must fly within the pilot's line of sight. Commercial drone pilots are also required to be at least 16 years old and will need to pass an Aeronautical Knowledge Test at a certified testing center before they can get their remote pilot certificate. Fully automated flights like the Amazon's planned delivery service or automated surveying devices are still not allowed.

A specialized division of the business software powerhouse SAP (System Application Products) is building tools to harness machine learning and artificial intelligence for antiterrorist intelligence missions and cybersecurity--though details of how exactly the software has been used are shrouded in secrecy. SAP National Security Services, which describes itself as an independent subsidiary of the German-based software giant that's operated by U.S. citizens on American soil, works with homeland government agencies to find ways to track potential terrorists across social media. "One [use] is the identification of bad actors: People that may be threats to us--people and organizations," says Mark Testoni, president and CEO of SAP NS2, as the company is known. "Secondarily, once we've identified those kinds of players and actors, we can then track their behaviors and organizations." SAP NS2 is also working with cybersecurity firm ThreatConnect to use some of the same underlying technology to track intruders and menaces in computer networks in real time, the companies announced this week.

Spreading processes are often modelled as a stochastic dynamics occurring on top of a given network with edge weights corresponding to the transmission probabilities. Knowledge of veracious transmission probabilities is essential for prediction, optimization, and control of diffusion dynamics. Unfortunately, in most cases the transmission rates are unknown and need to be reconstructed from the spreading data. Moreover, in realistic settings it is impossible to monitor the state of each node at every time, and thus the data is highly incomplete. We introduce an efficient dynamic message-passing algorithm, which is able to reconstruct parameters of the spreading model given only partial information on the activation times of nodes in the network. The method is generalizable to a large class of dynamic models, as well to the case of temporal graphs.

The market for artificial intelligence in the US is projected to grow at a CAGR of around 75% during 2016-2021. United States is the largest market for artificial intelligence solutions, globally. Continuous research and development in healthcare, autonomous vehicles, security and access control, cyber security, etc., are expected to fuel growth in the United States artificial intelligence market. Rising penetration of smart wearables, burgeoning head-up display screen market in luxury car segment and growing venture capital investments are also propelling adoption of artificial intelligence solutions in the country. United States government is also playing a proactive role in the country's artificial intelligence market by organizing workshops in association with leading solution providers.
