Omar Mateen, who killed 49 people at the club in Orlando, Florida, claimed to support Islamic State extremists, as well opposing groups such as Hezbolla and Nusra Front. Large crowds gather for the "OneOrlando Vigil" in the city where the rampage occurred, while other memorials are being held across the country. Officials scrutinized Omar Mateen for making radical, violent statements in 2013, then investigated him again in 2014 because he was casually acquainted with a suicide bomber. Donald Trump vows to impose bans on immigrants from parts of the world associated with terrorism, while Hillary Clinton warns that demonizing all Muslims would only play into the hands of extremists. Former British Prime Minister Gordon Brown calls for Labour Party supporters to vote to stay in the European Union.

For too long, the Electronic Entertainment Expo (E3) has existed inside a heavily shielded bubble, one in which game makers target retailers and journalists with carefully controlled messages designed to stoke the imagination of the most dedicated of game players. And what have those players wanted? Indeed, at the pre-conference events ahead of the Tuesday start of this year's E3, it seemed at first that nothing had changed. At L.A. Live on Sunday afternoon, Electronic Arts offered insiders a look at a sequel to "Titanfall," a military-esque shooter featuring giant robots, as well as the gritty, World War I-set "Battlefield I." Then Monday morning at Microsoft's bonanza at USC's Galen Center, cheers erupted during a demo of the latest "Gears of War" when a woman used a gun to obliterate an already downed creature. These sorts of displays do little to debunk age-old stereotypes about games and those who play them.

Xbox One is shrinking in size and growing in power. Microsoft unveiled during its Monday media briefing at the Electronic Entertainment Expo a new, slimmer version of the video game console coming later this year and a more powerful one that's due in 2017. The company says the white Xbox One S is 40 percent smaller than the original black Xbox One and will feature support for 4K high-definition video. Other changes include moving the USB ports to the front of the console, adding a built-in infrared blaster and eliminating the port for the motion-detecting Kinect camera system. Microsoft says the console will go on sale in August for 299 to 399 depending on the size of the hard drive.

Analysts are saying that Apple's upcoming updates to its Siri voice assistant should help the company address criticisms that it can't compete on artificial intelligence. Apple is now opening Siri to apps made by other companies, and like Google and Microsoft, it's bringing the digital assistant to desktop and laptop computers. It's also making Siri smarter by using what Apple calls differential privacy. Patrick Moorhead of Moor Insights & Strategy explains it as Apple using non-personal information in aggregate to teach Siri new tricks, then having all the personalization take place on the individual device. It's in contrast to Google's approach of doing everything over the internet -- that is, in the "cloud."

Two Belgian hospitals have added an innovative staff member to their reception desks: humanoid robots called Pepper. The robots took up assistant reception duties at hospitals in Ostend and Liege on Monday.. Related: Man v machine: can computers cook, write and paint better than us? The humanoid assistant, which has a screen on his chest and a round head, is the first robot in the world to be used to greet people in a medical setting, his software creators said. Standing 140cm (4ft 7in) tall and equipped with wheels under his white frame, Pepper can recognise the human voice in 20 languages and detect if he is talking to a man, woman or child. In Liege the robot helper, who costs about 30,000 ( 23,000), will for the moment remain in the hospital's reception area. But at the AZ Damiaan hospital in Ostend, he can accompany visitors to the department they are looking for, said Raphaël Tassart of the Belgian firm Zora Bots which developed the software inside his robot brain.

To hold its own against digital assistants from Google, Microsoft and Amazon, Siri needs an IQ boost Last month, Google took the stage in Mountain View, California, to show off improvements to its digital voice assistant. Its signature ability is to have a conversation with it like you would a normal person.

Nuclear energy provides electricity for a large segment of the global population, but it has one Achilles' heel that remains to be adequately addressed: the waste. According to a report from Business Standard, however, scientists from the DOE/Lawrence Berkeley National Laboratory have made a breakthrough finding that could lead to a viable solution to this lingering problem. A team of scientists has developed a new material that can clean up nuclear waste gases created as a byproduct of fuel reprocessing plants. The researchers say the material allows for the efficient, safe and cheap disposal of harmful byproducts of generating nuclear energy. The study was carried out by an international team based in Switzerland at the Ecole Polytechnique Federale de Lausanne (EPFL).

The Sorting Hat is no longer confined to fiction – a solutions architect for IBM Watson has developed a real-life version of the all-knowing Harry Potter artefact. Powered by multiple Watson services, the hat was trained to sort the wearer into one of the four Hogwarts'Houses' based on distinctive character traits. The researchers have added animatronics to the design to bring their sorting hat to life, including a voice, a moving mouth, and colour-changing LED eyes, and the smart hat has even tested its abilities by sorting the presidential candidates.

SAN FRANCISCO – Apple is working to make its iPhone and other gadgets smarter, responding to competitors' recent moves by building more artificial intelligence into its Siri digital assistant, photos, maps and other online services. The tech giant kicked off its annual software conference by announcing new software features for the Apple Watch and Apple TV, as well, while unveiling a new design for the Apple Music service. It's also extending Apple Pay to the web, so users can pay for purchases made on their Mac computers using the fingerprint authorization on their iPhone or Apple Watch. Most of these new features won't arrive until this fall. At a time when sales of its flagship iPhone are slowing, Apple seemed determined to show that it can make its gadgets indispensable, or at least as useful as its competitors' products.
