Your Fitbit (or whatever it is the activity-enlightened wear these days) can make a pretty good guess at how many calories you're burning through. And it can do it without any input from you. But if you want to keep track of how many you're putting in, you'll still need to do some work yourself, even if it's only choosing from a menu on an app. Inspired by that asymmetry, State University of New York at Buffalo computer scientist Wenyao Xu and colleagues at Northeastern University in China developed Autodietary, a necklace-like gadget that attempts to tell what you're eating. The device senses sounds from your neck to categorize your meal.

UPDATE Mar 12th 2016: AlphaGo has won the third game against Lee Sedol, and has thus won the five-game match. That was the score, as The Economist went to press, in the latest round of the battle between artificial intelligence (AI) and the naturally evolved sort. The field of honour is a Go board in Seoul, South Korea--a country that cedes to no one, least of all its neighbour Japan, the title of most Go-crazy place on the planet. To the chagrin of many Japanese, who think of Go as theirs in the same way that the English think of cricket, the game's best player is generally reckoned to be Lee Sedol, a South Korean. Mr Lee is in the middle of a five-game series with AlphaGo, a computer program written by researchers at DeepMind, an AI software house in London that was bought by Google in 2014.

"The fourth industrial revolution is unlike anything humankind has previously experienced. New technologies are merging the physical, digital and biological worlds in ways that create both huge promise and potential peril. The speed breadth and depth of this revolution is forcing us to rethink how countries develop, how organizations create value and even what it means to be human." We are living in an increasingly complex and uncertain world of constant change unlike anything in history. Advances in technology are outpacing implementation and these emerging technologies whilst presenting brilliant opportunities for a more positive world also present potentially detrimental threats.

He spells out a series of threats that all boil down to poorly constructed cost functions that result in unintended consequences.

Although the Google Photos app is only 10 months old, the service has already amassed more than 100 million monthly active users. The reason Google's cloud-based photo management software has gained so many users so quickly? It makes organizing photos dead easy. It automatically backs up all your images from all of your devices into one central location, plus it collects pictures of the same people or objects into groups, and helps you find images in your archive with text searches. No wonder it's already become an integral part of photo organization for so many people.

FRANKFURT (Reuters) - Nearly a decade after the iPhone broke the mould for mobile phones the question is now being asked whether the evolution of the smartphone has finally come to an end as even Apple now treats older, smaller 4-inch screens as something new. Industry experts believe innovation in smartphones is giving way to phone functions popping up as software or services in all manner of new devices from cars to fridges to watches and jewellery rather than remaining with handheld devices. And analysts and product designers said fresh breakthroughs are running up against the practical limits of what's possible in current smartphone hardware in terms of screen size, battery life and network capacity. "Everything in the phone industry now is incremental: slightly faster, slightly bigger, slightly more storage or better resolution," said Christian Lindholm, inventor of the easy text-messaging keyboards in old Nokia phones that made them the best-selling mobile devices of all time. The financial stakes are high as the futures of Apple, Google, and Microsoft, the world's three biggest listed companies at the end of last year, may turn on who gets the jump on making handsets redundant.

The ability to access and use financial services is critical to managing day-to-day life, weathering unexpected events, and capturing opportunities. Yet, some 46 percent of working-age adults in developing countries remain excluded from the formal financial system. It means they use the age-old informal mechanisms such as the moneylender, the pawnbroker, or the rotating savings club that can be unreliable and very expensive. In developed countries, working families are more likely to be under- or badly served rather than outright excluded. In the US, for example, every year some 25 million households use alternative services such as payday lenders or check cashers.

Every day new travel sites and apps are launched that promise to make trip planning easier. Some do and some don't. Here are two free tools optimized for smartphones that I tested and really liked: Lonely Planet's free Guides app for iOS and Android, and Destinations on Google, which makes it easy to aggregate information for your next travel adventure. The app includes more than 35 free importable guides to international and U.S. destinations, from Bangkok to London and Boston to San Francisco. I tested New York, Kyoto and Vancouver.

Boiteux, an assistant fire chief from Los Angeles, is helping train Greek first responders to use Emily. Boiteux, an assistant fire chief from Los Angeles, is helping train Greek first responders to use Emily. On a cold, rainy morning a few weeks ago, eight black inflatable rafts, loaded with migrants, bob in the waters off the northern shore of the Greek island of Lesbos. "This boat up there?" he says. So they ask for help from the coast guard." A Norwegian rescue boat with the European Union's border agency, Frontex, heads toward the distressed raft. Hantzopoulos walks along the rocky shore with John Sims, a fire captain from Sahuarita, Ariz. He's teaching members of the Hellenic Red Cross how to use a remote-controlled rescue device called Emily -- which stands for Emergency Integrated Lifesaving Lanyard. You might call Emily a buoy. You might call her a boat. She's about 4 feet long, weighs 25 pounds and looks like a cylinder wrapped in an orange-red life jacket. Sims steers Emily in the water with a remote control. She speeds toward the migrant rafts. "I'll keep her about 20-30 meters behind [them]," he says. The only thing that affects her sometimes over a wave is a little bit of wind. In a high wind situation we would actually fill the hull with some water to be able to weight her down some so, so, she wouldn't fly so bad off the top of the waves."
