Earlier this year, the social media website Facebook announced that it would work with several news organizations — including The New York Times, The Guardian, and the BBC — to place news stories directly into users' personal Facebook webpage.  Stories published using Facebook Instant will load more quickly and keep the style of the original publisher, who will keep all the advertising income the stories earn — at least for now. The deal shows how important social media has become to news organizations, and is a clear sign of how the world of news is changing — and has been for a while.

    When Google News began in 2002, many saw it as the death of the newspaper. It had no human editor. Instead Google used, and still uses, a secret computer program that selects and displays news stories according to the reader's personal interests. More recently, Associated Press and Yahoo! have been publishing computer-written articles. Both use special software to automatically produce stories about company financial results and sports reports — areas where the quality of writing is felt to be of secondary importance to the accuracy of the data.

    Should we be worried about such developments? I think we should. One concern is that facebook, Google and other social media websites see journalism as a sideline, a way of putting people in front of advertisements. It isn't their primary function — so if it stops making them lots of money, they're likely to stop doing it.

    There's also a concern that computer-written articles are not actually journalism at all, because what a human news team produces is actually quite complex. A well-written news story puts information in context, offers a voice to each side of an argument and brings the public new knowledge.

    Though economics and speed of delivery mean readers will probably choose a computer-written story over a carefully shaped article — at least for daily news — I don't think the computers will be writing any in-depth articles for a while yet.

    Below is a selection from a popular science book.

    If blood is red, why are veins（静脉） blue?

    Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it's outside the body, when it's sitting in the vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

    Which works harder, you heart or your brain?

    That kind of depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

    Why do teeth fall out, and why don't they grow back in grown-ups?

    Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they are gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.

    Do old people shrink as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They lose height as their spine（脊柱） becomes shorter and more curved due to disuse and the effect of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose and average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards —- their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved.

    Why does spinning make you dizzy（眩晕的）?

    Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you'removing while you're not.

    Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area —- from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.

    If exercise wears you out, how can it be good for you?

    Because our bodies adapt to everything we do to them. And as far as your body is concerned, it's “use it, or lose it”! It's not that exercise makes you healthy, it's more that a lack of exercise leaves your body weak and easily affected by disease

The Grand Palace

    If there is one must-see sight without which no visit to Bangkok would be complete, it's the spectacular Grand Palace, undoubtedly the city's most famous landmark. Built in 1782 and for 150 years the home of the Thai King, the Royal court and the administrative seat of government, the Grand Palace of Bangkok continues to have visitors in awe of its beautiful architecture and complicated details, which is a proud salute (致敬) to the creativity and craftsmanship of Thai people. Within its walls were also the Thai war ministry, the state departments, and even the mint (铸币厂). Today, the complex remains the spiritual heart of the Thai Kingdom.

    Important Notes about the Grand Palace

    A strict dress code applies. The Grand Palace with the Temple of the Emerald Buddha is Thailand's most sacred site. Visitors must be properly dressed before being allowed entry to the temple. Men must wear long pants and shirts with sleeves (no lank lops). If you're wearing sandals or flip-flops you must wear socks, in other words, no bare feet. Women must be similarly modestly dressed. No see-through clothes, bare shoulders, etc. If you show up at the front gate improperly dressed, there is a booth near the entrance that can provide clothes to cover you up properly (a deposit is required).

    Price Range: Tickets sold from 8:30-15:30 and cost 500 baht! One ticket includes entry to Vimanmek Palace and Abhisek Dusit Throne Hall.

    Recently I read the Human Development Report. I couldn't help thinking about another problem which the world is facing--hunger. According to the report, 2,400 people are dying from hunger every day; nearly 13 million in southern Africa will be worried about their food supply because of earthquakes, floods or wars.

    In a word, hunger remains the biggest problem of the world today. It's strange to see that man can travel to the moon, but still doesn't know how to feed himself. You may ask, “Who steals our bread? The first thieves should be population growth, poverty and loss of rich farmland.

    In less developed areas like South Africa, the population grows faster than the crops. It is almost impossible for its government to feed so many people and provide education for them. So it is very important to control the population growth and protect their farmland in countries whose people are suffering from hunger.

    According to the report, the world's food production is enough to feed everyone if it is given away well. But the problem is that the developed countries are eating food that should be given to the poor. Although they are just using their own earning, the fact is that they are coldly watching others starving away.

    Luckily, some developed countries such as Netherlands, Norway and Sweden have done a lot to help those hungry people in African countries. We hope other developed countries will follow them.

    A few days ago I was sitting in a Thai restaurant enjoying a meal when I got a phone call from a friend I hadn't spoken to for a long time. Full of enthusiasm and excitement I talked slightly louder than usual and in Spanish, my mother tongue.

    A few minutes into the call the lady sitting beside me got up, seemingly upset, and asked the restaurant staff to relocate her to a table as far away as possible from “this man who won't get off his phone”.

    I sank in my seat out of embarrassment. I ended the call soon afterwards and felt the urge to go over and apologize. Before getting up I looked around to see where she was and I found she was, indeed, at the table furthest away from me. I noticed that the lady was alone and staring out of the window, looking a bit sad.

    Right then I quit my plan for a conventional apologetic gesture and decided to conduct an experiment. Seeing those funny smile cards in my wallet, I took one out. When signing my check I asked the waiter to secretly charge the lady's meal to my credit card instead of her bill.

    I left the restaurant, letting the waiter know I would be back in a few hours to pick up my credit card. I returned later as promised, excited to learn the result.

To my pleasant surprise, things turned out the best possible way. A group of restaurant staff approached me with joy, telling me that the lady had dined there many times, but they had never seen her smile and laugh like she did upon receiving the smile card and the $0 check.

    For most of her life, Suanne Laqueur's passion for storytelling was shown on the dance floor.

    Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother's dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: "Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn't want to own it."

    Yet Laqueur's disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

    Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Goodreads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer's Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

    "You have to write the most truthful story to you, and I think self-publishing allows that freedom,' she says. "If you work with traditional publishing, it's more about what's marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I'm cool with that."
