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

The Chinese dissident artist, Ai Weiwei said that he will release a documentary film next year on the refugee crisis. Ai, often described as China's most high-profile artist, was speaking at a news conference in Bern to mark the opening of the "Chinese Whispers" exhibition, featuring around 150 works of contemporary Chinese artists - including Ai Weiwei artwork "Fragments"- at the Zentrum Paul Klee museum in Bern. Ai said he has spent a lot of time in refugee camps in recent months and witnessed a "very difficult situation" and decided to share his experience by making a film. "It's a documentary film, we have been shooting over 600 hours, and I've did hundred of interviews, there is all kind of people: politicians, refugees or priests or NGOs…all kind of people involved in this crisis," Weiwei told reporters. Chinese dissident artist Ai Weiwei looks on as he visits a migrant's makeshift camp on the Greek-Macedonian border, near the village of Idomeni, Greece, March 9, 2016.

Catastrophic climate change, nuclear war and natural disasters such as super volcanoes and asteroids could also pose a deadly risk to mankind, researchers said. It may sound like the stuff of sci-fi films, but experts said these apocalyptic threats are more likely than many realise. The report Global Catastrophic Risks, compiled by a team from Oxford University, the Global Challenges Foundation and the Global Priorities Project, ranks dangers that could wipe out 10% or more of the human population. It warns that while most generations never experience a catastrophe, they are far from fanciful, as the bouts of plague and the 1918 Spanish flu that wiped out millions illustrated. Sebastian Farquhar, director at the Global Priorities Project, told the Press Association: "There are some things that are on the horizon, things that probably won't happen in any one year but could happen, which could completely reshape our world and do so in a really devastating and disastrous way. "History teaches us that many of these things are more likely than we intuitively think."Many of these risks are changing and growing as technologies change and grow and reshape our world. But there are also things we can do about the risks."

The rise of robots and deadly viruses are among the threats that could wipe out swathes of humanity - but governments are failing to prepare properly for them, a new report warns.

Creativity is alive and well at Samsung, which is developing several cool devices in its labs, including a home companion robot called Otto. The multi-talented robot can answer questions and double as a part-time security system when needed.

Google's self-driving car just got a boost from the National Highway Traffic Safety Administration. SAN FRANCISCO - Federal auto safety and standards regulators should set rules governing self-driving cars and not state agencies that may not have the technological know-how to assess the rapidly evolving technology. That was the message delivered to federal administrators Wednesday by Chris Urmson, the chief architect of Google's seven-year-old autonomous car program. Urmson was one of a variety of auto experts speaking at a Stanford University forum organized by the National Highway Traffic Safety Administration, which is soliciting comments as it aims to establish a set of guidelines later this summer for companies developing autonomous cars. The event took place the day after Google announced it was part of the Self-Driving Coalition for Safer Streets, a lobbying group of autonomous-car focused companies that also includes Ford, Lyft, Uber and Volvo.

A robot assistant lifeguard called EMILY is making waves by helping migrants cross the Mediterranean Sea safely. In the wake of unrest, over 500 refugees have drowned attempting to cross the Mediterranean from Turkey to Greece. Members from the Texas A&M Engineering Experiment Station's (TEES) Center for Robot-Assisted Search and Rescue (CRASAR) and Roboticists Without Borders gathered at the Greek island of Lesvos to assist the local Coast Guard and lifeguard organizations to prevent this from happening in the future. Dr. Robin Murphy, Raytheon Professor in the Department of Computer Science and Engineering at Texas A&M University, aided authorities in Lesvos alongside CRASAR, of which she is an active member. She is working with students to continually improve the lifesaving device, which can carry up to eight people at once.
