Welcome to robot nursery school," Pieter Abbeel says as he opens the door to the Robot Learning Lab on the seventh floor of a sleek new building on the northern edge of the UC-Berkeley campus. The lab is chaotic: bikes leaning against the wall, a dozen or so grad students in disorganized cubicles, whiteboards covered with indecipherable equations. Abbeel, 38, is a thin, wiry guy, dressed in jeans and a stretched-out T-shirt. He moved to the U.S. from Belgium in 2000 to get a Ph.D. in computer science at Stanford and is now one of the world's foremost experts in understanding the challenge of teaching robots to think intelligently. But first, he has to teach them to "think" at all. "That's why we call this nursery school," he jokes. He introduces me to Brett, a six-foot-tall humanoid robot made by Willow Garage, a high-profile Silicon Valley robotics manufacturer that is now out of business. The lab acquired the robot several years ago to experiment with. Brett, which stands for "Berkeley robot for the elimination of tedious tasks," is a friendly-looking creature with a big, flat head and widely spaced cameras for eyes, a chunky torso, two arms with grippers for hands and wheels for feet. At the moment, Brett is off-duty and stands in the center of the lab with the mysterious, quiet grace of an unplugged robot. On the floor nearby is a box of toys that Abbeel and the students teach Brett to play with: a wooden hammer, a plastic toy airplane, some giant Lego blocks. Brett is only one of many robots in the lab. In another cubicle, a nameless 18-inch-tall robot hangs from a sling on the back of a chair. Down in the basement is an industrial robot that plays in the equivalent of a robot sandbox for hours every day, just to see what it can teach itself.

Now in its 30th year South by Southwest is synonymous with creativity and innovation for advertisers and marketers from around the world and this year has seen the program significantly expand with hundreds of new sessions catering to a record breaking 72,000 delegates across its interactive, music and film festivals. So beyond dizzying crowds, and the ever-present fear of missing out on the next big thing, what are some of the key trends to have emerged from the annual techie talkfest and what are the things which were hot in previous years but have now have lost their cool after going mainstream? Walking around Austin, VR is everywhere. Demand by festival goers to get their hands on the latest 360 experience has left people queuing day and night for their chance to play. Samsung, realising the round the clock queues their 5D sensory experience would attract, took things a step further with a tweet containing #VRonDemand summoning one of Austin's iconic hipster peddled pedicabs to your location wherever you were, taking the experience out of the showroom and into the streets. However, there was no sign of Microsoft's augmented reality visor the Hololens this year.

Say what you will about civilian drones and drone pilots, but when the going gets tough, these drone pilots will get going. According to published Federal Aviation Administration (FAA) commercial drone exemption requests, a big chunk of drone pilots are willing to lend a hand for possible emergencies. A total of 19 percent mentioned emergency services--that's six times as many requests from the last quarter of 2015. With all these pilots willingly to help out in case of emergencies, this could mean that private pilots can easily aid officials during search and rescue missions and other equally critical emergency scenarios. Despite this magnanimous offer to lend a hand, it doesn't necessarily guarantee pilots flying time.

DETROIT – As autonomous car technology rapidly progresses, makers of the cars face the difficult question of how safe they must be before they're ready to move people on highways and city streets. Right now, companies such as Google, Audi and Mercedes-Benz are testing the cars in a small number of cities to demonstrate they can be safer than human drivers. They also must figure out what level of risk is acceptable to both government regulators and a potentially skeptical public. Government statistics show that human mistakes are responsible for 94 percent of the 33,000 U.S. traffic fatalities each year. Autonomous cars won't get drowsy, distracted or drunk, so in theory they could eliminate those mistakes and save an estimated 31,000 lives a year.

We've seen experimental drones that rule that skies with speed and even mounted weapons, but a new flying drone prototype has emerged that will lie in wait for you somewhere new: under the sea. A team at the Johns Hopkins University Applied Physics Laboratory designed the CRACUNS (Corrosion Resistant Aerial Covert Unmanned Nautical System) drone to withstand both underwater pressure and the corrosive effects of salt water. See also: Pentagon confirms it has used spy drones in U.S. air space Based on a series of tests performed by the team, CRACUNS can remain submerged at a depth of several hundred feet for at least two months and then emerge from the water and elevate itself into the air using four rotor blades. To accomplish the feat, the drone researchers housed the device's components in a dry pressure vessel and coated its motors in unnamed, commercially available coatings. The CRACUNS drone is at home under water or in the air.

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

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.

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.

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.
