Imagine one day walking into a gorgeous structure--like LA's famous Walt Disney Concert Hall--only to discover it was designed by a computer system and constructed by automated robotic arms. Ai Build, a London-based startup, aims to pave the way to 3D printing on large scales. The company is equipping industrial-grade Kuka robotic arms with artificial intelligence and "3D printing guns" to 3D print large structures that focus on maximizing efficiency with labor and materials. Founder and CEO Daghan Cam dreamed up the technology while considering traditional commercial construction and wondering what a more efficient and automated process might look like. In October, the company partnered with engineering consulting firm Arup Engineers to debut the 3D printed "Daedalus Pavilion" at the GPU Technology Conference in Amsterdam.

When aliens come, how will they get here? Well, unless they are sly infiltrators of the flesh, they will probably go for the kind of boastful, get-a-load-of-us craft that was immortalized by Douglas Adams in "The Hitchhiker's Guide to the Galaxy." He wrote, "The ships hung in the sky in much the same way that bricks don't." That was true of "Independence Day," and it is doubly true of "Arrival," in which a dozen mountainous ovoids--charcoal gray and rough to the touch, like a pumice stone--show up at various locations around Earth. Rather than land, the vessels suspend themselves in dignified fashion, with their tips facing downward and not quite touching the ground.

Zoltan Istvan was in town recently, campaigning as the Presidential nominee of the Transhumanist Party. He was on track to appear on the ballot in zero states. "Politicians keep having the same old arguments about tax policy and Social Security," he said. "Transhumanists want to talk about how science can help us radically transform the human experience, how we can cure death and disease and upload our consciousness into the cloud, things like that." He was on a street corner in SoHo.

Anti-drone defense systems are about to become big business. T-Mobile parent company Deutsche Telekom has confirmed to Welt am Sonntag that it's developing an anti-drone defense system that should launch this year. It's not discussing details, but it would be offered as a security feature for airports, stadiums and other venues where robotic flyers are unwelcome or outright dangerous. Reportedly, car manufacturers are particularly eager for Deutsche Telekom's help -- they're annoyed by journalists (and no doubt competitors) using drones to snap photos of pre-production cars. Welt sources understand that the system (which was tested in July) involves technology from multiple companies, including US-based Dedrone.

Facebook has been forced to end a hugely controversial data sharing agreement with WhatsApp. The decision would have seen WhatsApp hand out information on all of its users to Facebook, letting the latter use data about people's chats to inform its advertising. It would also have gone the other way – allowing companies to send WhatsApp's to people based on things they've bought on Facebook, for instance. But now the UK's Information Commissioner's Office has told the company that it needs to bring that arrangement to an end because it does not have "valid consent" from its users. Facebook had looked to gain permission from its users to have their data used as part of the deal.

While most of us find it easy to recognise highly familiar faces such as those of family and friends, identifying faces that we have only briefly encountered is much more difficult. In fact, some research suggests that even experienced passport control officers make a large number of errors when matching faces to identity documents. Yet, recent work reveals that a small number of people may have extraordinary face recognition skills, outperforming typical people on a range of face recognition tasks. Bath researchers found that a small number of people may have extraordinary face recognition skills, outperforming typical people on a range of face recognition tasks. 'Super recognisers' have an uncanny ability to recognise faces, remembering people they have not seen for decades, who have substantially changed in appearance, and who they have only fleetingly encountered.

You're working in the garden when you notice your tomato plant is stunted and wrinkled. What is your next step? A team of researchers from Penn State University and the Swiss Federal Institute of Technology in Lausanne (EPFL) believes you should reach for your phone. They are building a free app called PlantVillage that can recognize plant disease from a mobile phone photo. Behind the app, expected to be available in early 2017, is a database of 150,000 photographs of diseased plants--a number the team intends to grow to three million.

A Barbie doll that uses artificial intelligence to communicate interactively. Oren Etzioni, a well-known AI researcher, complains about news coverage of potential long-term risks arising from future success in AI research (see "No, Experts Don't Think Superintelligent AI is a Threat to Humanity"). After pointing the finger squarely at Oxford philosopher Nick Bostrom and his recent book, Superintelligence, Etzioni complains that Bostrom's "main source of data on the advent of human-level intelligence" consists of surveys on the opinions of AI researchers. He then surveys the opinions of AI researchers, arguing that his results refute Bostrom's. It's important to understand that Etzioni is not even addressing the reason Superintelligence has had the impact he decries: its clear explanation of why superintelligent AI may have arbitrarily negative consequences and why it's important to begin addressing the issue well in advance. Bostrom does not base his case on predictions that superhuman AI systems are imminent.

Media reports say an artificial intelligence (AI) system called MogIA, developed by Sanjiv Rai, an innovator based in Mumbai, has predicted that Donald Trump will win Tuesday's presidential elections in the United States. Unveiled in 2004, the system apparently got it right in the last three presidential elections. It also predicted that Trump and Hillary Clinton will be the nominees of the Republican and Democratic Parties respectively. Rai is quoted as saying that the algorithm got even better as it has "learnt" from the last few rounds. MogIA is named after Mowgli from The Jungle Book.
