Lightroom users who sync their photos to the app's Web module can now test out a new and improved way to locate specific images: Search. As part of a new Lightroom Technology Preview series debuting today, Adobe is making the search feature available to Creative Cloud Photography Plan subscribers to test and offer feedback before finalizing it. As described in a blog post Friday morning, Search lets you type in a keyword to enable Lightroom to display all related images it finds in your library, even images you never tagged or labeled. Macworld got to test out the new feature early, and it worked quite nicely. Just log in to your account, and click on the Lr logo at the top left to access the menu. There, you'll find the new Technology Previews feature.

Take a few minutes to launch these apps, just to ensure they're properly configured and will begin sending notifications. Don't forget Cortana--she'll preserve your preferences in the cloud, but she'll need you to tap her tile to wake her up. Unfortunately, you won't be able to use any of your newly upgraded hardware with the Microsoft Display Dock; in fact, the Continuum app, which enables phones like the Lumia 950 to project their screens onto external monitors, doesn't even appear.

The pilot of a Lufthansa passenger jumbo jet has reported that a drone aircraft nearly collided with his airliner on its landing approach to Los Angeles, according to the Federal Aviation Administration. The close encounter between the wide-body, four-engine Airbus A380 and the drone occurred at about 1.30pm at an altitude of 5,000ft (152 metres) as the unmanned aircraft passed about 200ft (61 meters) over the Lufthansa flight 14 miles (22.5 km) east of the city's international airport, the FAA said. No evasive action was taken by the airline crew, and the plane, Lufthansa Flight 456, safely made its landing minutes later without further incident, according to FAA spokesman Ian Gregor. The FAA immediately alerted the Los Angeles police department's air support division. The number of passengers and crew aboard the plane was not reported by authorities, nor was the flight's origin.

Everything you do changes your brain. Right now, wherever you are, looking at these words is shaping and modifying the connections between neurons inside your head. It seems like a scary thought, but this process – known as neuroplasticity – is fundamental to our ability to learn new skills, keep hold of old ones, and form new memories. Imagine, then, if we could take control of that process. If we could target specific types of skills and cognitive processes, then we could teach our brains to be better at, well, anything.

'AlphaGo" is the sort of supercomputer name a pulp science fiction novelist might come up with. Nevertheless, the achievements of this Google DeepMind machine are only too real. It has become the first computer program to beat a professional human player of the Chinese strategy game Go, without handicaps, on a full?sized 19 19 board. It shouldn't surprise us when computers beat humans at board games. They can, after all, store and rapidly analyse hundreds of millions of moves, and work out the implications of strategies hundreds of moves ahead, something no merely human player can manage.

At San Francisco's first fully automated restaurant, meals appear in little glass cubbies, just 90 seconds after customers order and pay on wall-mounted iPads. It's a human-less experience – no waitstaff, no cashier, no one to get your order wrong and no one to tip. The moment before the meal appears, the see-through display screen that fronts the cubbies goes black for the few seconds when you might catch sight of the hand that feeds you.

Baidu Inc. BIDU 2.44 % will soon start testing autonomous cars in the U.S., part of the Chinese tech giant's effort to introduce a commercially viable model by 2018. The move, disclosed by Baidu's chief scientist Andrew Ng in an interview late Tuesday, is a significant step for the company, which is trying to get ahead in the race to build autonomous cars and is now calling on the resources of its Silicon Valley tech center to advance the effort. At the same time, Baidu is advocating for better coordination with the U.S. government, which the company says is necessary to get self-driving cars on the road. Central to the push is Mr. Ng, an artificial-intelligence scientist who conducted groundbreaking research at Stanford University and at Alphabet Inc. GOOGL -0.40 % 's Google. Late last year, Beijing-based Baidu became the latest technology company to publicize its intention to develop self-driving cars.

"I feel a little regrettable because I believe that there is more that a human being could have shown in a match against artificial intelligence," Lee said following the final match. The matchup had all the mood and atmosphere of a prize fight. And play-by-play announcers who analyzed every move.

Last summer, Jacky Alciné learned just how biased computers can be. Alciné, who is African-American, took a bunch of pictures with friends at a concert. Later he loaded them into Google Photos, which stores and automatically organizes images. Google's software is able to group together pictures of a particular friend, or pictures of dogs, cats, etc. But when it labeled a picture of one of Alciné's friends, who is also African-American, it left him speechless.
