French writer Frantz Fanon once said: ＂To speak a language is to take on a world, a culture.＂ Since the world changes every day, so does our language.

    More than 300 new words and phrases have recently made it into the online Oxford Dictionary, and in one way or another they are all reflections of today's changing world.

    After a year that was politically unstable, it's not hard to understand the fact that people's political views are one of the main drives of our expanding vocabulary. One example is ＂clicktivism＂, a compound of ＂click＂ and ＂activism＂. It refers to ＂armchair activists＂ — people who support a political or social cause, but only show their support from behind a computer or smartphone. And ＂otherize＂ is a verb for ＂other＂ that means to alienate (使疏远)people who are different from ourselves — whether that be different skin color, religious belief or sexuality.

    Lifestyle is also changing our language. For example, ＂fitspiration＂ — a compound of fit and inspiration — refers to a person or thing that encourages one to exercise and stay fit and healthy.

    The phrase ＂climate refugee＂ — someone who is forced to leave their home due to climate change—reflects people's concern for the environment.

 According to Stevenson, social media was the main source for the new expressions. ＂People feel much freer to coin their own words these days,＂ he said.

    But still, not all newly-invented words get the chance to make their way into a mainstream (主流的) dictionary. If you want to create your own hit words, Angus Stevenson, Oxford Dictionaries head of content development, suggests that you should not only make sure that they are expressive (有表现力的) and meaningful, but also have an attractive sound so that people will enjoy saying them out loud.

    Shape

    According to their website, Shape is a magazine for American women with active lifestyles. This women's health magazine covers everything from diet and exercise to psychology. What is great about Shape is that it knows that it must cover a lot more than Fitness to give women all the information they need to stay healthy. Besides all the great features included in their print magazine, they also have an easily accessible website that anyone can use.

    Women's Day

    Women's Day is not only specifically a women's health magazine, but also includes a little of what Shape has, along with more information on other parts of life: family, money, travel and style. Many of the articles in Women's Day deal with specific diseases that are common to women, such as heart disease, breast cancer and others.

    Women's Health

    From tips to recent health news to articles about world affairs, Women's Health has everything that you expect in a women's health magazine. Another great feature is that Women's Health has a great website full of information, as well as articles from past magazines that you can check out. This is a great resource, since it lets you get to see articles well at the office.

    Fitness

    This magazine covers important topics such as physical fitness, health & beauty, and mental health. It offers something new in each issue, and it's always easy to understand.

    The workouts are clearly presented with good photos to illustrate (说明) every movement, and almost all can be done without making a trip to the gym.

    An interesting study posted on Facebook recently shows how men and women develop new interests as they mature(成熟).

    While women tend to take exercise seriously from the age of 34, men will wait until their 45th birthdays before working hard to get in shape. The average woman spends more time talking about sports, politics, career and money as she gets older.

Women's interest in books reaches its peak(顶峰) at the age of 22, while that of men does so when they are in their 50s.

    Men start to change their focus from the workplace to other things after age 30, while women do not do so until eight years later. Both, however, care most about fashion at age 16.

    The research used anonymous(匿名的) data donated by thousands of Facebook users, recording the statuses, 'likes' and 'interests' they had posted on their profiles.

It found the average woman talks about television most at 44, while men peak much younger, at age 31.

    Men are also most likely to see a film in a cinema at age 31, while women go out to see films most when they are only 19.

    Men are most interested in travel at 29, women at 27, while women talk most about food and drink at 35, and men at 38.

    And if you are middle aged, a safe topic for any audience is the weather, which is a key interest for many as they approach 60.

    Stephen Wolfram, the British scientist who carried out the research, says, “It's almost shocking how much this tells us about the changes of people's typical interests.

    “People talk less about video games as they get older, and more about politics.”

    Robots make me nervous—especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way.

Gates said in an interview with the social networking and news website Reddit: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent．That should be positive if we manage well. A few decades after that, though, the intelligence is strong enough to be a concern."

    Well, maybe I don't have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There's a terrible thought!

    Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies. What could put us in danger is that they might be too efficient. That's what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent to humans and in pursuit of their own goals，the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you.

    It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm.

I'm glad my machines at home are "dumb". All my cleaner wants to take over is the carpet in my living room. Let's hope they don't create an appliance which wants to take over the world!

    Crossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

    A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance(阻力), making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health problems. So, planning to sit for a long period of time? Don't keep your legs crossed.

    Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

    So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

    Feelings often run high where insects are concerned, with many people even sick when seeing them, let alone touch or swallow them. And yet insects present a huge nutritional opportunity as an increasing global population seeks more sources of food and feed.

    Insects have generally high levels of animal protein and key micronutrients with lower environmental footprints than traditional alternatives, and they can be raised on leftovers. But cultural, social and economic problems remain, reports an article published today in Nutrition Bulletin.

    “Insects present a nutritional opportunity, but it is unclear how their nutritional quality is influenced by what they are fed, "says Darja Dobermann, a researcher at the University of Nottingham.“In ideal conditions, insects have a smaller environmental impact than most traditional western forms of animal protein; less known is how to raise insect production while maintaining these environmental benefits.”

    “Studies overall show that insects could make valuable economic and nutritional contributions to the food or feed sys tems, but there are no clear regulations in place to bring insects into such supply systems without them turning into a more expensive version of poultry（家禽）for food,” says Dobermann.

    The article highlights how insects have been a source of food for hundreds of years in more than 100countries with over 2,000 species that can be eaten; in central Africa, up to 50% of dietary protein has come from insects, with their market value higher than many alternative sources of animal protein.

    Insects need to be large enough to make the effort of catching them worthwhile and easy to locate, preferably in predictably large quantities. They are consumed at various life stages, as raw, fried, boiled, roasted or ground food.
