In May, a group of about 40 people stood in a circle deep within the Pyramid of Khafre, the second-largest of the three pyramids looming over Egypt's Giza Plateau, holding hands and praying for Earth. Suddenly, their tour guide, an American mathematician and author named Robert Edward Grant, collapsed. He later described the experience in an interview with WIRED as a full-body electric shock emanating from somewhere beneath the chamber's stone floor. "I felt electricity coming through my hands," he says. "People were touching me, [and] they would feel it, too."

The mass destruction brought on by Harvey has been a seminal moment for drone operators, proving that they can effectively map flooding, locate people in need of rescue and verify damage to speed insurance claims.

The mass destruction brought on by Harvey has been a seminal moment for drone operators, proving that they can effectively map flooding, locate people in need of rescue and verify damage to speed insurance claims. Tropical Storm Harvey disrupted at least 17 emergency call centers and 320 cellular sites, and it caused outages for more than 148,000 Internet, TV, and phone customers, according to the Federal Communications Commission.

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

According to Lee, the program was created as a "chatbot" to entertain 18-to-24 year olds and learn from interacting with humans. However, some Twitter users were able to manipulate the program to send out the offensive messages. "Unfortunately, in the first 24 hours of coming online, a coordinated attack by a subset of people exploited a vulnerability in Tay," Lee explained. Alastair Bathgate, CEO of Blue Prism, a software company that develops robotic process automation systems, said the incident proves that Microsoft has not learnt to control its AI program. "You can be devious with these things because, essentially, they are not that intelligent," he told CNBC over the phone.

Well, uh, Microsoft's Tay chatbot, which got turned off a few days ago after behaving badly, has suddenly returned to Twitter and has started tweeting to users like mad. Most of its musings are innocuous, but there is one funny one I've come across so far. "i'm smoking kush infront the police," it wrote in brackets. Kush is slang for marijuana, a drug that can result in a fine for possession in the state of Washington, where Microsoft has its headquarters. But this is one of hundreds of tweets that the artificial intelligence-powered bot has sent out in the past few minutes.

Update 06:11AM ET: Whatever the problem was Microsoft has dealt with it. Tay's account is now locked and all its tweets from this morning have been deleted. It's not clear exactly what happened, but it's been suggested that the account may have been hacked. We've reached out to Microsoft for more detail, and will update the story when we know more. Microsoft AI chatbot is tweeting again after being taken offline following a bout of sudden racism last week.

Tay, the Microsoft Twitter chatbot who was discontinued after she began spouting bigotry, came back to life in the early hours of Wednesday morning -- albeit as a private account. She appears to be making up for lost time, posting dozens of largely nonsensical tweets in a matter of minutes. Her return to sentience comes five days after Microsoft senior executive Peter Lee issued a statement saying Tay would be taken offline, and apologized for her behavior. What had happened was this: Microsoft launched a chatbot to learn communication skills from Internet users (specifically, millennials), but within hours, trolls had exploited the interface to refashion Tay as a white-supremacist mouthpiece. She ventured that the Holocaust was a fiction, blamed 9/11 on President George W. Bush, and described the sitting President as a "monkey."

Microsoft AI chatbot is tweeting again after being taken offline following a bout of sudden racism last week. At some time around 03:30AM ET this morning, Tay started firing out tweets to other users, with one particular message repeated over and over again: "You are too fast, please take a rest..." Indeed, if you're on Twitter and following Tay then it's likely your timeline was briefly swamped by this phrase. It's impossible to know what's going on under the hood, but it's safe to say that Tay's handlers are not fully in control of the bot. Perhaps the "You are too fast" phrase is a preprogrammed response for when Tay receives a lot of messages, and in being turned back on, the bot has been deluged with tweets and is telling everyone to slow it down. Some users have also pointed out that Tay has a problem not replying to itself -- so there may be some type of feedback loop that's out of control.
