China agreed Saturday to return an American sea drone it had captured after the Pentagon demanded it back, defusing tensions at the end a week of confrontations over Beijing's territorial ambitions in the South China Sea. China's Defense Ministry said it would return "in an appropriate manner" the U.S. sea vessel seized this week by the Chinese navy. But the ministry also accused the U.S. of "public hyping" that was "not conducive to solving the problem smoothly." Chinese officials did not specify what happened or when Beijing would hand back the device. The ministry, in a statement, said the device was unidentified when found and that officials later concluded it was an American drone.

While artificial intelligence is a loaded term that for some may conjure up images of a malicious Skynet system from the Terminator movie franchise, the reality is not as ominous. And when Sen. Ted Cruz, R-Texas, argued during the U.S. Congress' first AI hearing -- dubbed "The Dawn of Artificial Intelligence" -- that it is already at work in the United States, improving the efficiency and productivity of systems across the map, he was right. "Artificial intelligence is already seeping into our daily lives," said Cruz, who is chairman of the Senate subcommittee on Space, Science and Competitiveness. The hearing, which included representatives from Microsoft, Carnegie Mellon University and NASA, among others, focused on the potential implications machine learning will have on the country's labor market, national security and transportation. One of the largest areas for growth through artificial intelligence is smart city planning and smart infrastructure.

Ford announced it will plans to start testing its autonomous vehicles on European roads by next year as it ramps up its robot car strategy. According to Digital Trends the U.S. car manufacturing goliath is moving ahead with European testing as it pursues its ambitious strategy to introduce fully autonomous vehicles for ride-hailing by 2021. "It is important that we extend our testing to Europe," said Ford of Europe's manager for Automated Driving Thomas Lukaszewicz. "Rules of the road vary from country to country here, traffic signs and road layouts are different, and drivers are likely to share congested roads with cyclists." Testing will begin at Ford's Engineering Center in Essex, U.K. After this, trials will be expanded to its Germany-based Research & Advanced Engineering facilities in Cologne and Aachen.

I'm going to get around to Watch Dogs 2, but it's going to be by way of a semi-lengthy tangent into Assassin's Creed--particularly, what Assassin's Creed II meant to that now-juggernaut of a series. It's easy to forget, with almost a decade of sequels under our belt, that there was a time when Assassin's Creed could've conceivably died off. After garnering quite a bit of hype, the original Assassin's Creed released in 2007 to middling reviews. "Disappointing," said many, or "Repetitive." It had some great ideas, but was a boring mess of a game.

As in the global survey, we are concerned with platform business models and the design choices that allow these business models to grow. We find the term platform, which is well-established in economic and management literature, offers a more useful and accurate term than some of the terms that have been used such as "share economy companies," "internet companies" or, even more broadly, "tech companies." Network effects are a key characteristic that distinguish platforms from other business models. As more users engage with a platform, the more attractive the platform becomes to potential new users. When more users attract more users, a dynamic is created that in turn triggers a self-reinforcing cycle of growth.

In one corner of John Knoll's office at Lucasfilm stand three racks of imposing black computer servers. The sleek 6-foot-tall towers, complete with mechanical switches and fans, flash blue LEDs. Each bears the insignia of the Galactic Empire from Star Wars and a name--Death Star 748, Death Star 749. As impressive and menacing as the machines appear, they aren't real. They're just faceplates wired with Arduino controllers to make the lights blink and flutter like actual computers. They are, in other words, visual effects--and a look into the mind of Knoll, the 54-year-old chief creative officer of Industrial Light & Magic, Lucasfilm's famed VFX arm. They're what made the movies. They come from the machines that spent roughly 13,000 hours rendering digital effects for the three Star Wars prequels, on which Knoll was a lead effects supervisor. The march of Moore's law turned the server farm that created those movies into scrap. "It took a few weeks," Knoll says, shrugging.

And their goal is to help you find the food court. Friendly faced humanlike looking machines are greeting shoppers at two malls in the San Francisco Bay Area this week in what could be the beginning of a new way we shop and eventually do everything. The robots, all named Pepper from SoftBank Robotics in Japan, are already working alongside humans at hotels, shopping centers, and other retail spots in parts of Asia and Europe. The emotional machines were introduced originally in Japan back in 2014. Slowly they are making their way to America.

From sashimi to tartare, tuna is in demand year-round. More than half of the world's high-grade fish supply comes from the central and western Pacific Ocean, a region that accounts for a $7 billion market. The popularity of tuna sustains small fishing communities in distant places like Palau. But it also threatens an aquatic population that has been dwindling at an alarming rate. Over the past few years, unregulated fishing practices in tuna-rich Pacific regions have threatened to wipe out rich species like the bluefin and bigeye.

Various reports have surfaced in the past year about unmanned aerial vehicles (UAVs) delivering packages and take-out to your door -- but some options are closer to the ground, literally. And one Silicon Valley city is jumping to test out this new technology, considered the newest frontier in automated delivery. Redwood City, Calif., recently passed a city resolution (PDF) for a nine-month pilot program in which Starship Technologies works with parcel delivery, grocery and food delivery firms who will use its autonomous robots to carry out the deliveries. As a demonstration for the city, the robot delivered a box of cookies from a local bakery. The company has run pilot programs in London; Düsseldorf, Germany; Bern, Switzerland; and Washington, D.C.

Samsung dominates the smartphone industry so much so that one in every five handsets sold worldwide come from the South Korean technology giant. But the firm is still reeling from the recall of millions of its big-screen Galaxy Note 7 devices, which suffered from a battery issue that could cause the device to overheat and, in some cases, explode. That recall left Samsung without a flashy new smartphone to go head-to-head with Apple's iPhone 7 and Google's Pixel as the all-important holiday shopping season approaches. "In a market that is otherwise maturing, Christmas has come early for vendors looking to capitalize with large-screened flagship alternatives like the Apple iPhone 7 Plus and Google Pixel," said IDC analyst Melissa Chau in a report accompanying the research firm's latest smartphone sales estimates. With the Note 7 dead and buried, Samsung must look towards the future for salvation.
