Artificial intelligence is learning to take on an increasing number of sophisticated tasks. Google Deepmind's AI is now able to imitate human speech, and just this past August IBM's Watson successfully diagnosed a rare case of leukemia. Rather than viewing these advances as threats to job security, we can look at them as opportunities for AI to fill in critical gaps in existing service providers, such as mental healthcare professionals. In the US alone, nearly eight percent of the population suffers from depression (that's about one in every 13 American adults), and yet about 45 percent of this population does not seek professional care due to the costs. There are many barriers to getting quality mental healthcare, from searching for a provider who's within your insurance network to screening multiple potential therapists in order to find someone you feel comfortable speaking with.

It's Monday lunchtime and gym-goers at Virgin Active in Moorgate, London, are grabbing a bike for their group cycle class. But this isn't any ordinary spin class, where the teacher enthusiastically shouts instructions like "sprint" and "climb" and the backdrop is an uninspiring grey wall. This is the "Pack", a class divided into three teams that compete in a series of interactive challenges while each rider's bike data is tracked in real-time and projected on to a screen. "We created the Pack in response to the growing demand for cycle-based classes and technology that tracks workout progress," says Virgin Active group chief information officer Andy Caddy. "It creates a wholly differentiated group cycle offering."

VIDEO: San Jose airport unveils robots to help passengers Robots at center of China's strategy to leapfrog rivals Robots at center of China's strategy to leapfrog rivals Robots at center of China's strategy to leapfrog rivals REDWOOD CITY (KRON)--Redwood City officials approved a pilot program this week that allows robots to deliver groceries and restaurant food to homes and businesses. Starship Technologies Inc. will launch the service with 20 robots. It will begin next month and last for nine months. Each robot is designed to carry three grocery bags and use nine on-board cameras to navigate. They travel four miles per hour and will be controlled by someone when they are crossing intersections, city officials said.

It's hard to believe that Black Friday and the 2016 holiday shopping season are almost here. The good news for those of us shopping for personal consumer electronics and tech gadgets for friends and family this holiday season is that there are some real bargains. Tech innovation has improved dramatically over the last year and because of competition the pricing has come down significantly. This year, I've structured the holiday tech gift guide a little differently. I had the opportunity to review many products this year, but I've narrowed the guide down to my top 30 featured products -- from tablets and phones to cameras and drones. I'm also putting together a future gift guide of less costly tech items in categories like kids, health/fitness, home/security and audio so be on the lookout for that. Always remember to check online for the lowest current prices on these items as most will be discounted as we get closer to the holidays. Remember, Hanukkah begins on the evening of December 24 this year. The Surface Pro 4 is the perfect holiday gift for a loved one looking for a device for work or play -- especially for the student who doesn't want to schlep around a heavy computer laptop. Powered by an Intel Core processor, it offers up to nine hours of battery life. Paired with the $60 Surface Pen you can use it for detailed sketches and handwritten notes.

Want to know if chatbots are gaining ground on apps? A Citi analyst, for example, reported that bots are growing at a much faster pace than mobile apps did at this same stage. In the realm of personal finance, bots have the real potential to radically improve the way we manage our money, weaving financial decisions into the fabric of our daily lives and giving us immediate insight into the long-term effects of our spending, saving, and investing habits. For instance, in the near future, when you walk into Starbucks, Siri might gently suggest that instead of spending $5 on a coffee this morning, perhaps you should put those dollars toward your child's college fund, which you've been neglecting lately. To further nudge you in the right direction, she might also let you know how that $5 investment in a college fund will appreciate over time and remind you that the single coffee purchase holds no long-term value. You compromise and opt for drip coffee instead of a latte, putting the leftover $2.50 into your child's 529 plan.

Behavioural change is a very tricky thing. We humans are so fickle. We see a bright shiny wearable device that can track our every move and we think it's our "silver bullet", a "ticket" to achieving our health and fitness dreams. Only for guilt to set in, as after a short time, the wearable device winds up in our top drawer. We knew the fitness data was great, but we really didn't know what to do with it. The truth is, behaviour change requires much more than data. Many programs have realized the magnitude of the problem and created incentive programs to reward people for being active, so they get a small pay-off on the road to achieving fitness. But in spite of these rewards, the drop-out rate remains problematic.

Today's technology is better than us in many areas of expertise. Artificial intelligence (AI) already beats us in games. It does a better job diagnosing illnesses. Cars, trucks, ships, trains and airplanes will soon drive themselves. In the future, artificial superintelligence will go beyond the abilities of homo sapiens. When robots manufacture our goods autonomously, and AI serves most of our needs, what will be left for us to do?

Back in the 90s, I used to design automated systems to help pilots fly civil aircraft. Today, this would probably be called designing artificial intelligence (AI) or smart systems or something similar. One of the big questions for us back then was deciding how much responsibility to give to the aircraft to fly, manage failures and generally make and execute decisions, as well as how much to leave to the pilots. One of the hot issues was whether the pilot or smart systems should have the final call when things got tough. Controversially, in several cases, authority was given to the aircraft because the aircraft could manage specific situations better.

A dream is a succession of images, ideas, emotions, and sensations that usually occurs involuntarily in the mind during certain stages of sleep.[1] The content and purpose of dreams are not fully understood, though they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recorded history. The scientific study of dreams is called oneirology.[2] Dreams mainly occur in the rapid-eye movement (REM) stage of sleep--when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.[3] The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes.[3] People are more likely to remember the dream if they are awakened during the REM phase. The average person has three to five dreams per night, and some may have up to seven;[4] however, most dreams are immediately or quickly forgotten.[5] Dreams tend to last longer as the night progresses. During a full eight-hour night sleep, most dreams occur in the typical two hours of REM.[6] In modern times, dreams have been seen as a connection to the unconscious mind. They range from normal and ordinary to overly surreal and bizarre. Dreams can have varying natures, such as being frightening, exciting, magical, melancholic, adventurous, or sexual. The events in dreams are generally outside the control of the dreamer, with the exception of lucid dreaming, where the dreamer is self-aware.[7]

An Australian man's idea to use a drone to bring a hot dog to his hot tub hit a snag when aviation authorities warned he could face fines of up to A$9,000 (about $6,970; £5,600) for breaching drone flight safety rules. The man, named by local media as "Tim", has insisted the stunt was safe but that the sky-borne sausage was "freezing" by the time it reached him.
