Dallas police respond after shots were fired during a protest over recent fatal shootings by police in Louisiana and Minnesota, Thursday, July 7, 2016, in Dallas.

Dallas police respond after shots were fired during a protest over recent fatal shootings by police in Louisiana and Minnesota, Thursday, July 7, 2016, in Dallas. Snipers opened fire on police officers during protests; several officers were killed, police said. When Dallas police used a bomb-carrying robot to kill a sniper, they also kicked off an ethical debate about technology's use as a crime-fighting weapon.

Machines that "learn" and make decisions on their own are proliferating in our daily lives via social networks and smartphones, and experts are already thinking about how we can engineer them so that they don't go rogue. So far, suggestions have ranged from "training" self-learning machines to ignore certain kinds of information that might teach them racism or sexism, to coding them with values like empathy and respect. But according to some new work from researchers at the Universidad Autónoma de Madrid,as well as other schools in Spain, the US, and Australia, once an AI becomes "superintelligent"--think Ex Machina--it will be impossible to contain it. Well, the researchers use the word "incomputable" in their paper, posted on the ArXiv preprint server, which in the world of theoretical computer science is perhaps even more damning. The crux of the matter is the "halting problem" devised by Alan Turing, which holds that no algorithm is able to correctly predict whether another algorithm will run forever or whether it will eventually halt--that is, stop running.

Daniel Dennett (1942 –) is an American philosopher, writer and cognitive scientist whose research is in the philosophy of mind, philosophy of science and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science. He is currently the Co-director of the Center for Cognitive Studies, the Austin B. Fletcher Professor of Philosophy, and a University Professor at Tufts University. He received his PhD from Oxford University in 1965 where he studied under the eminent philosopher Gilbert Ryle. In his book, DARWIN'S DANGEROUS IDEA: EVOLUTION AND THE MEANINGS OF LIFE, Dennett present a thought experiment that defends strong artificial intelligence (SAI)--one that matches or exceeds human intelligence.[1] Dennett asks you to suppose that you want to live in the 25th century and the only available technology for that purpose involves putting your body in a cryonic chamber where you will be frozen in a deep coma and later awakened.

In May, a Tesla TSLA 0.39 % "autopilot" enthusiast in Florida became the first known fatality in a self-driving car. But this was no ordinary accident. The car performed exactly as designed, and the (non)driver's failure to take any corrective action could reasonably have been foreseen by the manufacturer. This unwelcome yet widely anticipated milestone may set back progress on what promises to be one of the most valuable technologies of the 21st century. In its rush to get hot new products into consumers' hands, Tesla--along with many other car manufacturers--has pursued a flawed vision of the future, one in which tomorrow's technology is simply layered on top of today's.

A robot carrying an explosive device was used to kill one of the shooters in Thursday night's horrific violence in Dallas, Texas, in what many law enforcement and other experts are calling the first such use of robotics technology by U.S. police. Five police officers were killed and seven others were wounded, along with two civilians, during a demonstration protesting the recent deaths of two African-American men at the hands of police in other cities. Micah Johnson, the man suspected of shooting the officers, was killed by remotely detonated explosives on the robot after a standoff and failed negotiations with police. Toby Walsh, a professor of artificial intelligence at the University of New South Wales, cautions against seeing this use of a robot as a nightmarish science-fiction scenario--because the robot was being operated by a human via remote control. "In [that] sense, it was no more taking us down the road to killer robots than the remote-controlled Predator drones flying above the skies of Iraq, Pakistan and elsewhere," Walsh told Scientific American in an email.

Microsoft has officially made Project Malmo, its Minecraft-based artificial intelligence research platform, available to all through Github. The open-source system was previously only available to a small group of researchers. The system, which had until now only been open to a small group of computer scientists in private preview, is primarily designed to help researchers develop sophisticated, more general artificial intelligence, or AI, that can do things like learn, hold conversations, make decisions and complete complex tasks. Minecraft may seem an odd choice for studying artificial intelligence, but Microsoft notes that researchers involved in the private preview were keen on its "endless possibilities for collaboration and exploration" as an ideal testing ground for AI research. In addition, Microsoft notes that the public launch heralds the arrival of new tools to the platform, like the ability to run experiments at a much faster pace (called overclocking), that should be a boon to researchers.

There's nothing quite like a cold pint of beer to remind you that everything will be alright with the world - but what about a hoppy, alcoholic beverage that's been finely brewed by a booze-obsessed artificial intelligence? That's what the IntelligentX Brewing Company is offering with its new AI Beer. Yes, a brewery has designed a series of algorithms that actively improve its beer recipes over time - in fact, the company's Pale, Amber, Black and Golden varieties have been tweaked 11 times since the AI went live. So does an AI make a bottle of beer better? IntelligentX says it's all about using an online feedback system that uses questions ranked from one to 10 to determine customer responses to its products.

Just the sight of a juicy, red strawberry on a bright green stalk conjures up English summertime, Wimbledon and afternoon tea. And the market for British strawberries is growing. But if rules on who can come and work in the UK change following the vote to leave the European Union, who is going to pick them? To pick a ripe strawberry, you don't just yank it. The pickers at Langdon Manor Farm in Kent are astonishingly quick at it.

Many models used by police are about the size of a backpack.

Several hundred people filled Thanks-Giving Square in downtown Dallas on Friday for an interfaith service hosted by dozens of clergy. A rabbi spoke, then an imam, a Methodist and a Baptist. A dozen uniformed police looked on, wearing black bars over their badges in honor of their fallen comrades. Mayor Mike Rawlings reminded the crowd when the square was erected: in 1964, a year after President John F. Kennedy was assassinated here, a bloody legacy that would haunt the city for decades. In recent weeks, people gathered in the square to mourn victims of the mass shooting in Orlando, Fla.
