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

Companies today are awash in data, but current tools and processes are not enabling them to keep it secure. That's according to Informatica CEO Anil Chakravarthy, whose says his company -- which has traditionally focused on data management and integration -- is embarking on a major push to go further into data security. "You hear about breaches all the time -- just imagine all the ones you're not hearing about," Chakravarthy said in a recent interview. "Data security today is an unsolved problem for customers." Last year, Informatica launched a product called Secure@Source that promises a data-centric approach to information security by helping organizations identify and visualize sensitive data wherever it resides.

LONDON - FEBRUARY 03: (FILE PHOTO) In this photo illustration the facebook logo is reflected in the eye of a girl on February 3, 2008 in London, England. Social networking site'Facebook' reaches it's 5th birthday this month. It was founded in 2004 by Mark Zuckerberg from his dorm room at Harvard University with the aim to help students keep in touch over the internet. Within 24 hours 1,200 Harvard students had signed up. The site now has 150 million active users worldwide. Facebook is opening up its image-recognition artificial intelligence research to the public.

As machine-learning becomes increasingly embedded into our everyday lives, Dr David Bray, a 2015 Eisenhower Fellow, Visiting Executive In-Residence at the Harvard Kennedy School and CIO at the US Federal Communications Commission, explores both the possible positive opportunities and potential cyber-security challenges. "The exponential changes being driven by digital technology are typically painted in a highly positive light. Just look at the average Internet minute during 2013: more than 204 million emails were sent, more than 4 million Google search results were conducted, more than 2.4 million items of Facebook content were uploaded and more than 72 hours of video were uploaded to YouTube. But it's worth remembering that technology itself is amoral: it's how we humans choose to use it that decides whether it's good or bad. The more challenging side of the exponential era is evident elsewhere: in 2013, cyber-security technology company McAfee identified 200 new threat vectors ...

Why is it that some people crave several cups of coffee a day while others stop at only one or two? A growing body of evidence suggests that the amount of coffee we consume is determined by our genetic makeup rather than the amount of sleep we got the night before. Coffee is one of the most popular beverages worldwide, second only to tea and water, researchers say. And drinking hefty amounts of coffee has been associated with several health benefits. Recent reports have linked coffee consumption with improvements in short-term memory, as well as a reduced risk of developing multiple sclerosis, melanoma, Type 2 diabetes and liver cancer.

The world's first-ever self-driving taxis hit the roads in Singapore on Thursday in a limited public trial. The "robo-taxi" service is taking place in a hi-tech business district in the western part of the country, where developer nuTonomy has been conducting daily autonomous vehicle testing since April. The company said that it had invited select Singapore residents to use its ride-hailing smartphone app to book a free ride in a nuTonomy self-driving car that employs the company's sophisticated software. The company's plan is to get feedback ahead of a planned launch of the service in Singapore in 2018. "Throughout the trial, nuTonomy will collect and evaluate valuable data related to software system performance, vehicle routing efficiency, the vehicle booking process, and the overall passenger experience," the company said in a statement. The rides will be provided in a Renault Zoe or Mitsubishi i-MiEV electric vehicle, specially configured by nuTonomy for autonomous driving.

IBM scientists together with colleagues at the Swiss university ETH Zurich have claimed a breakthrough in efforts to build a machine that computes like a human brain.

The world's first self-driving taxis will be picking up passengers in Singapore starting Thursday. Select members of the public will be able to hail a free ride through their smartphones in taxis operated by nuTonomy, an autonomous vehicle software startup. While multiple companies, including Google and Volvo, have been testing self-driving cars on public roads for several years, nuTonomy says it will be the first to offer rides to the public. It will beat ride-hailing service Uber, which plans to offer rides in autonomous cars in Pittsburgh, by a few weeks. The service will start small -- six cars now, growing to a dozen by the end of the year.

In many Western democracies, right-wing populists, energised by self-proclaimed victories over "establishment elites", are doubling down on the claim that globalisation lies at the root of many citizens' problems. For those whose living standards have stagnated or declined in recent decades, even as political leaders have touted free trade and capital flows as the recipe for increased prosperity, the argument holds considerable appeal. So it must be addressed head on. Of course, economic grievances alone do not fuel anti-globalisation sentiment; populism has emerged even in countries with low unemployment and rising incomes. But such grievances provide the kernel of truth that populist leaders need to attract support, which they then attempt to secure with distortions and exaggerations.
