Did you know that the position(位置) you choose to sleep in says something about what kind of person you are?

    A study of 1,000 British people has been done by Chris Idzikowski, a British professor and director of the Sleep Assessment and Advisory Service in the UK. It looked at the six most common sleeping positions and which personalities tend to match them. Have a look:

    ⒈Fetus (胎儿) position – This is the most common sleeping position. About 41 percent of the participants said they sleep in this position. These sleepers may appear to be strong but they are usually sensitive (敏感的) and shy. The more they curl (蜷缩) up, the more worried they are.

    ⒉Log position (树干睡姿) – This is the second most common position. People who sleep like a log are usually stubborn.

    ⒊Yearner position (向往型睡姿) – This position says that you are open-minded and eager (急切的) to face challenges.

    ⒋Soldier position – These sleepers lie on their backs with their arms down and close to the body. They are usually reserved and quiet.

    ⒌Freefall position – People who sleep in this position are outgoing (外向的) but feel a lack of control in their lives. This is the least comfortable position.

    ⒍Starfish position – People who sleep like this are good listeners, helpful, and uncomfortable being the center of attention.

    Public transport is declining in the rich world. To those who have to squeeze onto the number 25 bus in London, or the A train in New York, the change might not be noticeable. But public transport is becoming less busy in those places, and passenger numbers are flat or falling in almost every American city. That is despite healthy growth in urban populations and employment.

    Although transport agencies blame their unpopularity on things like road works and broken signals, it seems more likely that they are being outcompeted. App-based taxi services like Uber and Lyft are more comfortable and convenient than trains or buses. Cycling is nicer than it was, and rental bikes are more widely available. Cars are cheap to buy, thanks to cut-rate loans, and ever cheaper to run. Online shopping, home working and office-sharing mean more people can avoid travelling altogether.

    The competition is only likely to grow. More than one laboratory is developing new transport technologies and applications. Silicon Valley invented Uber and, more recently, apps that let people rent electric scooters(滑板车) and then abandon them on the pavement. China created sharing-bicycles and battery-powered "e-bikes", both of which are spreading.

    Transport agencies should accept the upstarts, and copy them. Cities tend either to ignore app-based services or to try to push them off the streets. That is understandable, given the rules-are-for-losers attitude of firms like Uber. But it is an error.

    It is doubtful that most people make hard distinctions between public and private transport. They just want to get somewhere, and there is a cost in time, money and comfort. An ideal system would let them move across a city for a single payment, transferring from trains to taxis to bicycles as needed. Building a platform to allow that is hard, and requires much sweet-talking of traditional networks as well as technology firms. It is probably the secret to keeping cities moving.

    Unbelievable Stories of Animals Acting Just Like Humans

    Horses are picky eaters

    Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can't sense. This might explain why they refuse dirty water and carefully mover around meadows, eating only the tastiest grasses, experts say.

    Whale says thanks

    In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.

    Pandas like to be naughty

    Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger.

    A cat honors its owner

    Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo's grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away. Toldo followed the coffin to the cemetery, and now “stands guard” at the grave for hours at a time.

    Six months after a Chinese scientist was widely condemned for helping to make the world's first gene­edited babies, he remains out of public view, and new information suggests that others may be interested in undertaking the same kind of work outside the United States.

    A clinic in the United Arab Emirates city of Dubai emailed scientist He Jiankui to seek training in gene editing, Stanford University bioethicist Dr. William Hurlbut said ahead of a speech Tuesday at the World Science Festival in New York.

    Hurlbut, whose advice He often sought, said He told him that scientists from multiple countries and families with inherited health problems had messaged support and interest in altering the genes of embryos(胚胎)to prevent or treat disease. Hurlbut gave The Associated Press the email the Dubai clinic sent to He in December but decided to hide the clinic's name.

    "It reveals what eagerness there is out there to use this technology" and the need "for some sort of practical governance" of it, Hurlbut said.

    Jennifer Doudna, a University of California, Berkeley, co­inventor of the CRISPR gene­editing tool that He used, said that she also has heard of others who want to edit embryos.

    "I think they're entirely credible," she said of such reports. Doudna, who was also a speaker at the New York festival, said the field needs to focus on setting specific principles for how and when such work should proceed.

    "The technology is frankly just not ready for clinical use in human embryos," although research should continue, she said. Doudna is paid by the Howard Hughes Medical Institute, which also supports AP's Health and Science Department.

    Scientists and policy leaders have been debating how to set international standards or controls since He claimed in November that he had altered the genes of twin girls at conception(怀孕)to try to help them resist possible future infection with the AIDS virus.

    Editing embryos is outlawed in many countries because it risks damaging other genes, and the DNA changes can be passed to future generations. Many scientists have condemned He's work, and attention has fallen on other scientists who knew or strongly suspected what He was doing.

    Until the 1990s coffee was rarely served in China except at luxury hotels aimed at foreigners. When Starbucks opened its first outlet there in 1999, it was far from clear that the country's avid tea-drinkers would take to such a different-and usually more costly- source of caffeine. Starbucks tried to attract customers unused to coffee's bitter taste by promoting milk and sugar-heavy concoctions(调和) such as Frappuccinos.

    But coffee has become fashionable among the middle class in China. Starbucks now has about 3, 800 outlets in China- more than in any other country outside America. Statista, a business-intelligence portal(门户网站), says the roast coffee market in China is growing by more than 10 % a year. Starbucks and its rivals see big opportunities for expanding there.

    So too, however, do home-grown competitors. A major new presence is Luckin Coffee, Beijing- based chain. Since its founding less than two years ago, it has opened more than 2,300 outlets. On May 17th Luckin's initial public offering on the Nasdaq stockmarket raised more than $570m, giving it a value of about $4bn.

    Luckin's remarkable growth is sign of change. No longer do Chinese consumers see coffee as such a luxury. Most of Luckin's outlets are merely kiosks where busy white-collar workers pick up their drinks, having ordered them online. Super-fast delivery can also be arranged through the company's app. Independent coffee shops are springing up. The growth is striking given the country's reputation for its tea-drinking culture where many residents like to relax in teahouses sipping tea served gracefully.

    But the two markets are different. The teahouses tend to cater to older people who like to spend long hours playing mahjong and gossiping. At the coffee shops it is rare to see anyone over 40. Young people use them for socialising, but much of their interaction is online -sharing photos of their drinks and of the coffee-making equipment. An option on the Chinese rating app Dianping allows users to search for wanghong ("internet viral") coffee houses: ones with particularly photogenic decor(照片装饰) where better to sip and We Chat?
