Carmakers and tech companies are in a race to put autonomous vehicles on the road, and it's time for regulators to tap the brakes. This month the National Highway Traffic Safety Administration revealed that it is investigating two crashes involving Tesla vehicles allegedly operating on autopilot. Tesla's autopilot feature is a semi-autonomous system that uses cameras, radar and sensors to steer the car, change lanes, adjust speed and even find a parking space and parallel park. It's not supposed to turn a Tesla sedan into a self-driving car, but there's ample evidence on YouTube of people driving with their hands off the steering wheel, playing games and even climbing into the back seat while their car is hurtling down a freeway. You and your daughter are riding in a driverless car along Pacific Coast Highway.

Following the death by bomb-armed-robot of the suspect in last week's cop killings in Dallas, which apparently involved an improvised setup that the local police department's robot wasn't built to be used for, a public outcry over police access to high tech weaponry has erupted. "The Dallas Police Department's unprecedented use of an explosive-laden robot to kill an armed suspect ushers in a new phase in the militarization of U.S. police departments," reports the Los Angeles Times. The article goes on to point out that there have been similar uses of modified machines originally built as anti-bomb robots, particularly in the military. But Dallas is certainly the most high profile domestic policing use so far, and experts say it could have lasting implications. "If lethally equipped robots can be used in this situation, when else can they be used?"

The depths of the ocean can be a dangerous place, even for a drone. Incredible footage has captured the moment a Great white shark mistakes the machine for food and attacks it with amazing speed and precision. It is believed the video was filmed off the coast of Australia where Great whites are commonly spotted in southern waters from Exmouth in Western Australia to Southern Queensland. The video shows the metal drone sitting deep in the ocean, when almost out of nowhere the underwater beast appears. Within seconds the Great white wraps it teeth around drone and viciously tugs at it before realising the hunk of metal is not a tasty meal.

Segway creator Dean Kamen's Luke prosthetic arm has been a long time in coming -- the FDA approved it two years ago. Mobius Bionics has revealed that it will offer the Luke arm sometime in late 2016. It's not clear what it will take to get one (you can register your interest today), but the features remain the same. The bionic wearable is all about offering the life-like dexterity that hasn't really been an option until now: you can hold a glass over your head without spilling it, for example, and the hand's mix of four motors and grip sensors can help you grab both very delicate and very heavy items. The odds are that getting one won't be trivial, but it might well be justified if it grants some extra freedom.

The race to build the world's first true quantum computer is on, with huge potential payoffs for businesses that harness the technology before their competitors. The computers we use today represent information in binary bits – on/off, 0/1 – while a quantum computer's qubit can, in simple terms, be both on and off the same time. That means many computations can be performed in parallel; a quality that, when fully realised, will give quantum computers a huge speed advantage over'classical' computers in solving certain problems. Microsoft and IBM are ploughing significant sums into related research. Google, NASA and Lockheed Martin have invested in a D-Wave 2X -- described by its maker as the "world's first commercially available quantum computer", although debate rages over its capabilities.

Ed Felten, the deputy U.S. chief technology officer for the White House Office of Science and Technology Policy, says humans have two major responsibilities when it comes to the development and advancement of artificial intelligence. The first, he says, is "to make the benefits of A.I. a reality." The second: "to address the risks of A.I." Felten was speaking to a roomful of people at New York University's Skirball Center for the Performing Arts at AI Now -- a summer lecture series co-sponsored by the White House that sought to examine and discuss key issues related to the future of A.I. technology. A.I. is at a crossroads, AI Now co-chairs Kate Crawford (a researcher at Microsoft Research) and Meredith Whittaker (the founder and lead for Google Open Research), pointed out. Private and public sectors need to work together to create some sort of feasible A.I. policy.

In this June 22, 2016, file photo, Democratic presidential candidate Hillary Clinton gestures as she speaks during a rally in Raleigh, N.C. Here's the tech news you need to know to start your week. The company just brought out Pokémon Go, an augmented reality smartphone app, and it is proving wildly popular. A major scheduled change means that "miners" -- people who create new bitcoins -- will only get half as many rewards for their efforts. Its Live Video feature is trying to dominate live events, and was used last week to broadcast the aftermath of a US police shooting.

Popular search engines are great at finding answers for point-of-fact questions like the elevation of Mount Everest or current movies running at local theaters. They are not, however, very good at answering what-if or predictive questions--questions that depend on multiple variables, such as "What influences the stock market?" In many cases that shortcoming is not for lack of relevant data. Rather, what's missing are empirical models of complex processes that influence the behavior and impact of those data elements. In a world in which scientists, policymakers and others are awash in data, the inability to construct reliable models that can deliver insights from that raw information has become an acute limitation for planners.

"The only thing that stops a bad guy with a gun is a good guy with a gun." Well, that gun lobby rubbish was again disproved in Dallas. Twelve good guys -- law enforcement men and women trained to shoot -- were stopped by one bad guy. Five officers were killed and seven wounded. Two civilians also were injured before the bad guy was finally stopped by a bomb-carrying robot.

Retired U.S. Air Force Col. Gene Lee (seated) is operating a simulator developed by Nick Ernest (standing left) for military training and research. Ernest, a University of Cincinnati graduate and Psibernetix president and CEO, is standing next to David Carroll of Psibernetix. Gene Lee has decades of experience as a fighter pilot and aerial combat instructor. The talent Lee, a retired U.S. Air Force colonel, has as a pilot allowed him to easily and consistently defeat other computer programs used in research and training. That was until he began working with a system developed by a University of Cincinnati doctoral graduate in collaboration with the Air Force Research Laboratory based at Wright-Patterson Air Force Base.
