Everyone who has eaten instant noodles knows that it's very easy to cook them quickly. However, have you ever heard of the danger of eating them?

When taking out the noodles from the packaging, you will notice that they are joined together nicely as a piece. Do you know that it needs some form of wax coating (蜡涂层) to make them joined together nicely? Many people don't really care much about it because this seems very normal. However, studies have shown that the wax coating is bad for our body.

    It is advisable to have a break of 2-3 days before we start to eat another packet of instant noodles because our body needs about 3 days to clear that wax coating away. Do you know the danger of having too much wax coating in our stomach? It will lead to CANCER if it is in our body for so long.

    Luckily, there is a way to reduce the danger before we eat instant noodles. First, wash the noodles with warm water, stir (搅拌) them and pour away the water containing the wax coating. Then repeat the first step and try to stir them again to wash away the wax coating on the noodles before cooking them. The shop vendors (供应商) will often wash away the dangerous wax coating.

    It is very easy to cook instant noodles but we must pay attention to the wax coating if we eat too much. Imagine having too much of it in your stomach. Oh, my! Hope this article will help more people know about the hidden danger!

    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.

    Recently we made a survey and asked a large number of people to tell us about their teachers. Here is what they remembered about their teachers:

    "What teachers do I remember? Well, I remember my first teacher. She was so kind and pretty, and she told us many interesting stories."

    "I remember an English teacher —— he always had colored socks: red, green, even orange."

    "I remember a math teacher. She always dressed very well. I couldn't stop looking at her. I wanted to be like her."

    "Our chemistry teacher. He was so strict. We were afraid of him. I don't think he liked us."

    "The physics teacher was so boring. He could make us fall asleep very quickly!"

    "One year we had a really good Chinese language teacher. He was very patient and told very funny stories. He was popular with all the class. We always worked hard for him. We are his friends."

    "The PE teacher always said I was stupid. I thought teachers should give us encouragement. I am not interested in sports because of him."

    "I had one history teacher who always wore clothes of the same color. During the three years, I never saw him change."

    "I remember two teachers well. One was my music teacher who was very active, and usually had a loud voice. The other was my computer teacher who was very serious, but he really helped me when I had problems at any time."

    Eating is best when it's a social activity. Think of the meal a family enjoys in the evening when everyone's together after work or school, or the big get-togethers over food at Spring Festival. But now, in the age of the Internet and social media, anyone with an Internet connection can enjoy a social eating event.

    Mukbang-a South Korean phrase meaning “eating broadcast”-is an unusual food fanaticism that's sweeping the country. This is a meal where only one person gets to eat, while many viewers watch live shows of hosts eating large quantities of food. They leave comments on the dishes the host is taking, and the host responds to them live.

    So why have people taken to this unusual new food trend(趋势)? Jeff Yang, an Asian-American cultural critic, thinks that it's down to “the loneliness of unmarried or uncoupled South Koreans”. He believes that eating on your own can be hard in a country like South Korea, where social eating is such a long tradition. However, Mukbang gives people the feeling that they are part of something larger, it seems.

    Millions of people have trouble with food. Either they eat too much of it, or too little. Some say that the popularity of Mukbang helps people with these disorders. Those who always eat too much and put on weight can watch Mukbang live shows to satisfy their appetite (胃口). And those who don't eat enough can build their appetite by watching delicious food being eaten.

    Even though Mukbang is a South Korean phenomenon, it's also taken off in the US. But unlike South Koreans who sit down to enjoy noodles and kimchi (泡菜), Americans enjoy their own native dishes. This means that viewers of US Mukbang live shows will see locals stuffing themselves with hamburgers, fries and ice cream.

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.

    Recently, the Oxford English Dictionary, or OED, added about 1,000 words and new definitions to its website. The changes are to help users understand a mix of terms, some dating back many centuries. The additions include words such as "brencheese", "deathshildy" and "hip-pop".

    The new entries are part of the company's update to oed.com, its searchable online dictionary for paid members. The OED makes changes to the website four times each year. But the latest print version has been in process since the year 2000, and may not be ready for 10 more years. That information comes from Katherine Connor Martin, who heads the company's dictionary operations in the United States.

    Usually, the OED watches usage of a word for at least 10 years before deciding whether to add a new entry, new definition or word related to an existing entry, she said. This general rule, however, is sometimes not followed. That is what happened with "tweet", a word that the OED added far before the 10-year mark. Other times, the company adds words that are very old, but were not included in the dictionary in the past.

    “It's funny because we talk about new words, but many of the words we add are already obsolete. It's just that they were never in the dictionary before," Martin told the Associated Press.

    That is the reality, she said, of a historical dictionary trying to put more than 1,000 years of English into books that already have over 855,000 entries. So, you get "brencheese", a rarely used term for when bread and cheese are eaten together. The word dates back to the year 1665. The word "deathshildy" is from Old English. It means someone who is guilty of a serious crime and condemned to death.

    The website defines the term "hip-pop" for music that combines parts of hip-hop and popular music. The OED discovered the term “hip-hip pop” was used in a 1985 story from a Pennsylvania newspaper. It noted that the term "hip-pop" appeared in a 1991 U. S. newspaper report about the rap artist M.C. Hammer.

    The website has added several other terms related to modern culture. They include three popular terms: "binge-watching", "spoiler alert" and "microaggression".

    Here are a few other new entries if you long to read on.
