I was driving home from the gym with my children. It was approaching bed time.

    “My legs hurt, I can't walk to the car.” said my son, William. Then be sat on the ground regardless of whatever we said.

    “Maybe you just need a banana? They're good for tired bones.” his sister, Meredith, persuaded him in a wise way.

This was the first time I had heard of the banana's miracle(神奇的) cure for achy bones. It distracted(使分心) William and we were able to make it to the car. His wish for bone relief brought him energy and he persisted(坚持) the entire ride home. Upon arrival, he struggled out of the car and slowly went up 3 steps into the house. While he took his ”medicine”, we arrived on a suitable diagnosis (诊断) for his “illness” —a serious case of Banana Bone. He was probably just over—tired. He had a long day and played hard in the Adventure Room at the gym. Thankfully we kept some bananas in the fridge, and hugs and kisses were given as a booster (辅助药剂) , which gave him the courage to walk upstairs to sleep.

    Banana Bone sounds like something I've had before. The aching hasn't been in my bones so much as in my head and my heart. I think it's a condition related to stress, lack of rest and stretching of one's abilities. Perhaps you're experienced it too. It is about long days facing challenges or pressing against the edges of your own ability without any hope.

    That's when you realize Banana Bone doesn't have to be a physical illness. It can be mental. It can drive emotion. It means you can choose it or you can choose against it. It's not real. It' s your reaction to what's real. I know, it' s still not easy. But it' s part of “growing up”. We must have the courage to overcome it and I believe we can make it﹗

    My advice to you? Eat a banana and go to bed. You'll feel a lot better and be your fresh self in the morning.

    The new two-child policy is making job hunting more difficult for women when about 40 percent of them said they were asked whether they planned to have a second child during job interviews, according to a report in Chongqing.

    China dropped its decades-long one-child policy in October and allowed each family to have two children. The country now has about 270 million married women of childbearing age.

    This change has put millions of career women in a dilemma between family and career. Employers also face big challenges as more female workers will have two childbearing leaves, seven to eight months altogether.

    A human resources website www.job.cq.qq.com conducted a survey among 500 employers and 5,000 job seekers about how the two-child policy affects the job market.

    Though two thirds of employers said the policy would make no difference to their recruitment(招聘), the survey showed that more than 70 percent of job seekers believe that bearing a second child will make women less popular in the job market. Forty percent of employers said they will give priority to married women with two children, according to the survey.

    Lin Xia, 29, quit her job after giving birth to her first child. She is now preparing to return to work. After several inquiries at a job fair, she found that the employers are concerned about future birth plans. "I thought it would be easier to find a job after giving birth," she was quoted as saying by the website. "I had to answer whether I will have a second child before I could get a chance for a job interview."

    Liang Siqi, 23, a college graduate, said although employers did not ask her the child question yet, she will not plan to have two children. "It (having two children) will definitely affect my career and personal life, so I will have only one," she said.

    Zhou Jiansong, who is in charge of human resources at a large private high-tech group in Chongqing, said the company will discuss birth issues with interviewees in order to make a better work plans. "We fully respect a women's right to bear a child or two," he said. "But you don't want them to go on a childbearing leave soon after they join your company." The experts expect more labor dispute cases concerning childbearing leave rights when bearing a second child in future.

    You may have never heard of Lanthanum, Cerium or Neodymium, but these elements (元素) and others known as “rare earth” play a major role in modern technology. They can actually be found in many places on the earth, but not in quantities that can be mined. Only a few countries — China, America, India, Australia, Brazil and Malaysia have any that can be mined enough to be traded.

Even though some of these elements such as Cerium are as abundant as Copper, they are not found in concentrated amounts on the earth's surface. They are often mixed together with other metals, which makes extraction (提取) of these elements an expensive and an environmentally messy process. It was due to this reason that the term “rare earth” was invented.

    Rare earth metals are used widely in our life. Rechargeable car batteries, computers, iPhones, DVD players, computer monitors, televisions, lighting, lasers, glass polishing, and superconductors all use quantities of rare earth metals. Also, with the advancement in “green” technology like solar panels, these shiny materials are becoming more important than ever. An average electric car uses 10 pounds of Lanthanum for its rechargeable battery!

    America has large deposits (存储量) of rare earths and has one of the first mines. It was openedin Southern California in 1940. The element “Europium” was the first metal to be separated in quantity for use in color televisions. However, in the 1980's and 1990's, as China started producing these elements in Inner Mongolia, the mines in America and elsewhere could not keep pace. The mine in Mountain Pass, California also failed environmental regulations and shut down in 2002.

    Now, recognizing the importance of having more than one supplier of this important resource, other rare earth owning countries like India and Australia are either dusting off their rare earth mines or speeding up their production. It is believed that the debate over rare earths will become louder in the coming months and years.

    Imagine waking up one day and finding that your beautiful local beach is no more—gone, its fine white sand swept away by an abnormal storm. You go about your daily business for 12 long years and then suddenly the beach is back, all its glory restored by another storm. This is what happened on the island of Achill, off the coast of Ireland, where people are celebrating the return of the beautiful Ashleam Bay beach that was taken from them in 2005.

    That in itself is unusual enough, but the story gets even better! You see, another beach in Achill did a disappearing act once, but took much longer to return. The beach at Doonagh, located only six miles away from Ashleam Bay, was restored earlier in 2016 after waves created by spring storms had swept away all the sand in 1984, leaving just rock pools behind.

    There is local legend that stretches back hundreds of years that says this beach at Ashlcam Bay returns for a short every seven years then disappears again. But this time around it took a bit longer than that. It was last seen in 2005 and it stayed for a few months at that time before it was washed away again.

    As you can imagine, everyone on the island of Achill is thrilled to have their sandy beach back, and even though no one knows how long it's going to be around for, they are making the most of the time they've got before it disappears again.

    Some may be quick to believe climate changes cause the phenomenon, but that's not the reason these two beaches in Achill keep disappearing, Dr Kevin Lynch, a geographer at NUT Galway, says that these occurrences are the result of hydrodynamics (流体力学) and sediment(沉积物) supply, rather than climate changes.

    Regardless of what's causing them, disappearing and reappearing beaches are just part of what makes nature so fascinating.

    A large scale study has found a link between eating a diet based on organic food and having a reduced risk of cancer. If the new results are confirmed, promoting organic food consumption could be a promising preventative strategy against the disease, a team of researchers from several French institutions said.

    Among the environmental risks for cancer, there are growing concerns about exposure to different types of pesticides（杀虫剂） from farming. The impact of such chemicals on the human body is still not well understood but there are some indications that harmful effects can occur even at low concentrations.

    Meanwhile, pushed by environmental and health concerns, the organic food market continues to grow rapidly. Organic food is produced without the use of synthetic（合成的） fertilizers, pesticides, genetically modified organisms, and the use of veterinary（兽医的） medications.

    "Organic foods are less likely to contain pesticide remains than conventional foods, and studies have shown that an organic diet reduces exposure to certain pesticide," Julia Baudry, lead author of the study from the Centre of Research in Epidemiology and Statistics in France, told Newsweek.

    "In the general population, the primary route of exposure is diet, especially intake of conventionally grown fruits and vegetables. However, few studies have examined the association of organic food consumption with cancer risk."

    For the study, published in the journal JAMA Internal Medicine, a team of researchers examined data on the organic food consumption frequency and dietary intake of 68,946 French adults collected by an ongoing survey which began in 2009. They then followed up on these people at various points in the future.

    Participants reported how often （never, occasionally or most of the time） they consumed 16 types of organic foods including fruits, vegetables, soy﹣based products, dairy products, meat and fish, eggs, grains and legumes, bread and cereals, flour, vegetable oils and condiments, ready﹣to﹣eat meals, coffee, tea, and herbal tea, wine, biscuits, chocolate, sugar and so on.
