Baby girls make their way to dolls as soon as they can crawl, while boys will head for the toy cars,  a study has shown. The findings, the first to show consistent differences in very young babies, suggest there is a biological basis to their preferences.

    Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 babies aged nine months to 36 months. They were allowed to choose from seven toys. Some were boys' toys - a car, a digger, a ball and a blue teddy.  The rest were girls' toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.

    Of the youngest children (nine to 14 months), girls spent much longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents' view on which toys were more appropriate for boys or girls, and the children's choice.

    Dr Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go' while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the color of a newborn baby.”

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    Do you find it difficult to put down your mobile phone?

    If yes, you're not alone. These days, many people suffer from the stress of FOMO (fear of missing out). They reach for their mobile phones when they wake up in the morning, and for the rest of the day, they constantly scroll down (向下滚动) the timelines of their social media apps to get the latest updates.

    Despite the convenience smartphones bring, many people struggle with their digital habits.

    As Sameer Samat, US tech Company Google's vice president of product management, said in his speech at the 2018 Google I/O developer conference on May 8, 70 percent of people don't want to spend so much time on their phones.

    This is why during the conference Google introduced an app called Dashboard for the new version (版本) of its Android operating system. This new app includes well-being functions that aim to help users manage the time they spend on their digital devices.

    It all starts with a bird's-eye view. Dashboard allows users to look at all the details of their phone habits. For example, a user can see how many times they've unlocked their phone and how many times they've checked their social media apps, as well as how much time they spend on each app every day.

    Once the users see this information, they'll be able to make some changes. With the App Timer function, users can set a time limit for how long they can use each app for every day. After they've hit the limit, they won't be able to launch the app until the next day.

    But even if users become more mindful of their usage, they're still likely to be drawn in by notifications (通知). This is where the Shush feature comes in. It automatically (自动地) silences incoming calls and notifications when a user puts their phone face down.

    If people truly want to make full use of their free time instead of losing hours using their smart phones, these new functions are just one way of doing that.

After all, who needs to use an app to stop you from using other apps when the easiest answer would be just to use your willpower?

    Every person plans to run off to some tropical isle, but few do. Real life, family, work, and monetary limitations get in the way. Ian Fleming let none of these considerations stop him.

    After the war, Fleming set down his schedule. The first week of January saw him leave England and travel to Jamaica. The first week of March saw his return. He accepted his job at Kemsley newspapers without compromise—this portion of the year would be set aside for Jamaica or he would look elsewhere for employment.

    For 6 years Fleming traveled each winter to Jamaica, lounging in paradise, romancing women, chasing the sunset, but it was not until he faced the pressure of a married woman who was pregnant with his child did Fleming start the writer's journey which would change his life and popular culture forever. As Fleming waited in Jamaica for Anne's divorce to become final, he wrote the first draft of a novel, Casino Royale.

    Fleming's career as a writer deserves more examination than can be offered here, but suffice it to say, over the next 12 years, Ian Fleming transformed his elite existence, his arrogance, his style, and his acid wit into some of the greatest thrillers ever written. Fleming incurred the respect of authors as diverse as Raymond Chandler, Kingsley Amis, and Edith Sitwell. His fans included John, Jackie, and Bobby Kennedy, and his social circle included Prime Minister Anthony Eden, Evelyn Waugh, and Somerset Maugham.

    Fleming filled out the 12 years of Bond with great adventure journalism. Even in stories which had little action or pay off, such as his short non-fiction book, The Diamond Smugglers, the "Fleming-flair" ensured exciting reading. He wrote the "Atticus" column for the Sunday Times, proving a wonderful conduit for inside intelligence information, and clever rebukes (指责).

    Regardless of book sales or family obligations, Fleming managed to live the life he wanted. As the years passed, his passion for golfing increased so he took more time with it. Fleming's long-term fascination with America grew, so he traveled there more often.

    Ian Fleming's full life caught up with him through his heart. It may be that years of drinking and smoking took their toll, or that the butter-rich cooking Fleming loved was the culprit. Or maybe it was just genetics. Whatever the cause, Fleming's health declined in the late 1950s. This plus anxieties in the marriage increased Fleming's depression. With the success of Bond, the world came knocking at Fleming's door, and he had a harder time shutting those out that he did not want in his life.

    Nonetheless, Fleming fought the loosing battle of his weakening heart by throwing more fuel on the fire. He continued to drink and smoke, making some excuses but not many. He wrote books he wanted to read, and traveled the world with style and authority. By this time, Fleming had already earned his own fortune, created his own identity, and ruled his own literary empire.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.
