Facebook has started using a new artificial intelligence (AI) system to identify users showing warning signs of suicide. The AI has been trained to spot status updates and subsequent comments that could indicate someone was at risk. The algorithm would immediately send a report to a real reviewer, who could then contact the user with suggestions and resources to help if appropriate. At the moment, Facebook relies on a human reporting system regarding potential suicides, where friends of users can click a button to tell the company about concerning updates. But it is hoped more people will be helped by an automated system.

The Nintendo Switch is finally on sale across the world. The much-hyped – and risky – mixed-use console appeared to immediately sell out and only people who queued at midnight or pre-ordered long in advance were able to actually get their hands on one. The console is unusual because it is made to be used in a variety of different ways. It can be used either on the move or plugged into a TV, for instance, and its controllers snap off the side so that they can be used by one or two players. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.

With three kids and constant travel for work, John Hussey jumped at the chance to play an open-world adventure game like "The Legend of Zelda: Breath of the Wild" anywhere, anytime. After he heard about the Nintendo Switch, a hybrid game machine that works as both a console at home and a tablet on the go, Hussey ordered one in January even though it wouldn't arrive until Friday, when Nintendo's latest game machine debuts. Nintendo will need lots of traditional gamers like Hussey to redeem itself as a console maker, after being eclipsed by Microsoft and Sony in the game-console wars. But Nintendo will also need lots of casual gamers who are satisfied with playing on a smartphone and would never have dreamed of buying a $300 game machine. And in trying to appeal to many audiences, Nintendo risks not being the best at serving any one.

Amazon accidentally took down large swathes of the internet with just one typo. This week, many of the world's biggest websites and services stopped working because of a problem with Amazon Web Services, the platform that the retailer provides to power people's websites. One of its sites went offline because of the issue – and since thousands of websites rely on it, including many of the world's biggest, they immediately went competely offline or stopped working. Websites like Quora, Trello and some of the world's biggest news sites went offline or stopped working properly when the issue happened. It even emerged that people's houses broke down – internet-enabled ovens, lights and front gates stopped working as a result of the outage.

Taking a souvenir home from an art gallery no longer has to mean a trip to the gift shop. A new app lets people scan a work of art with their smartphone camera to find out more about it and save a digital copy. The app, called Smartify, uses image recognition to identify scanned artworks and provide people with additional information about them. Users can then add the works to their own digital collection. Smartify co-founder Thanos Kokkiniotis describes it as a combination of the music discovery service Spotify and music recognition app Shazam – but for visual works.

As more self-driving cars hit the road in the coming years, sophisticated communications systems will rely on a fast, reliable network that's capable of being a data superhighway. Self-driving or autonomous cars are a hot topic, but the road to autonomous driving is curvy and complicated. It's full of blind turns as engineers, automakers, regulators and data scientists map out a radically different future for automobiles. That future is fast approaching. In January, the BMW Group, Intel and Mobileye said a fleet of about 40 of their autonomous test vehicles will be on roads by the second half of 2017.

Artomatix founder Eric Risser's idea to use AI to create 3D worlds is not so crazy after all. Dublin artificial intelligence (AI) company Artomatix has raised €2.1m in a seed round. It is still the start of the journey for founder Dr Eric Risser as his company makes headway in enabling movie houses and games companies to create immersive 3D worlds. "No, we have no money for your weird AI arts stuff," Risser was told by a professor when he was a computer science student at Columbia University. He persevered, completed his PhD at Trinity College Dublin instead, and started a company.

If you have an Android phone running Android 6.0 Marshmallow OS and above, check it, you might have a new feature available -- the Google Assistant is now rolling out to all such devices. It is different from Google's previous voice offerings such as Google Now since it not only lets user conduct conversations with it, but also evolves according to usage. The rollout, which will occur in the form of a Google Play Services update, was announced last week. Gummi Hafsteinsson, Google Assistant product lead, said in the company's official press release issued on Sunday: "Our goal is to make the Assistant available anywhere you need it. It came to Android Wear 2.0--via new smartwatches--just a few weeks ago and, as we previewed in January, the Assistant is also coming to TVs and cars. With this update, hundreds of millions of Android users will now be able to try out the Google Assistant."

LONDON – Scientists in Britain have for the first time created a structure that resembles a mouse embryo using a 3D scaffold and two types of stem cells -- research that deepens understanding of the earliest stages of mammalian development. Publishing their results in the journal Science on Thursday, the team, based at Cambridge University, said that while the artificial embryo closely resembled the real thing, it would be unlikely to develop further into a healthy mouse fetus. For research purposes, however, the scientists were able to show how the artificial embryo followed the same pattern of development as a normal embryo -- with the stem cells organizing themselves in the same way. Magdalena Zernicka-Goetz, a professor at Cambridge's department of Physiology, Development and Neuroscience who led the work, said the success with mouse cells should pave the way for similar work with human cells, helping scientists overcome a major barrier to human embryo research -- a shortage of embryos. Currently, human embryos for research are developed from surplus eggs donated through fertility clinics, but Zernicka-Goetz said it should in the future be possible to use the stem cells and scaffold technique to make artificial human embryos for study.

Dr. Stephen Roberts, director of the Oxford-Man Institute and professor of machine learning at the University of Oxford, tells Newsweek that the entire internet only recently matched the capacity of a single human brain. "It wasn't until 2010 that the sum total of internet traffic exceeded a zetabyte, and that's just a single human brain," Roberts said. Roberts was speaking at Newsweek's Artificial Intelligence and Data Science in Capital Markets conference, in London, March 2.
