Emily and her boyfriend had just had a fight. She felt alone and hopeless. Then she went into the kitchen and grabbed what she needed before going back up to her room quietly. She switched on the TV and started eating…and eating…for hours, until it was all gone.

     What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED)(暴饮暴食).

    For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess (承认) to BED, as they do to anorexia? It's simple: There's a stigma（污名）involved. “Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California.

    "Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper.

    Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own.

    Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge (狂欢).

    R. U. Darby and his uncle were digging for gold in the West. After weeks of labor, he was rewarded when he discovered shining ore(矿石). He needed machinery to bring the ore to the surface. So he borrowed money from his relatives and neighbors and went back to work on the mine.

    The first car of ore was mined and sent to a smelter. The gold that they got in return proved they had one of the richest mines in Colorado! A few more cars of that ore would clear the debts. Then would come the big profits.

    Down went the drills! Up went the hopes of Darby and Uncle! Then something happened! The vein of gold ore disappeared! The pot of gold was no longer there! They drilled on, desperately trying to pick up the vein again, but they found nothing.

    Finally, they decided to quit. They sold the machinery to a man for a few hundred dollars, and took the train back home. That man asked a mining engineer to look at the mine and do a little calculating. The engineer said that the project had failed because the owners were not familiar with “fault lines(裂纹线)”. His calculations showed that the vein would be found just three feet from where it was found.

    The man took millions of dollars in ore from the mine, because he knew enough to ask for expert advice before giving up.

    R.U. Darby was struggling for years to pay back the money from his relatives and neighbors. He went into the business of selling life insurance.

    Remembering that he lost a huge fortune because he stopped three feet from gold, Darby profited from the experience in his chosen work, by the simple method of saying to himself , “I stopped three feet from gold, but I will never stop because men say 'no' when I ask them to buy insurance.”

    Darby is part of a small group of fewer than 50 men who sell more than a million dollars in life insurance every year. His “stick-ability” comes from the lesson he learned from his “quit-ability” in the gold mining business.

    Global warming threatens to hold back human progress, and make unachievable all UN targets to reduce poverty, according to some of the world's leading international and development groups.

    In a report published today, Oxfam, Greenpeace and other groups say rich governments must immediately address climate change to avoid even “unbearable levels” of worldwide poverty.

     “Food production, water supplies, public health and people's livelihoods are already being damaged and weakened,” the report says. “There is no approach possible. The world must meet its commitments to achieve poverty reduction and also deal with climate change, which are closely linked.”

    The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food production, more disease and the extinction of entire eco-systems on which many of the world's poorest people depend.

     “Climate change needs to be addressed now. The poor will bear the great consequence of it. The frontline experience of many of us working in international development indicates that communities are having to fight more extreme weather conditions.”

    Climate change will cause great damage to agriculture and water supplies and will increase diseases. “By 2025 the number of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical (热带的) and sub-tropical areas will be hardest hit — those countries already suffering from food shortage”.

    Poor countries mostly do not need hi-tech solutions, but would most benefit from education, research and being shown how to farm better. The report says unchecked global warming, more than wars or political upheaval (政变), will displace millions of people and unsettle many countries.

A Teenage Inventor

    The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

    Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia's method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia's method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

    Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

    "What affects one country affects everyone," Olivia told CNBC. "We have to work together to find answers to the huge challenges which cause harm to the global health." The Connecticut's teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

    Olivia hopes her success will inspire other girls interested in science and computers. "I would just encourage girls to try it in the beginning, and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science," she told CNBC, "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests."

    Why do you go to the library? For books, yes--but you like books because they tell stories. You hope to get lost in a story or be transported into someone else's life. At one type of library, you can do just that--even though there's not a single book.

    At a Human Library, instead of books, you can "borrow" people. Individuals volunteer as human "books" and participants in the event can "read" the book--meaning they would have a one-on-one conversation with the volunteer and share in a dialogue about that individual's experience. "Books" are volunteers from all walks of life who have experienced discrimination (歧视) based on race, religion, class, gender identity, age, lifestyle choices, disability and other aspects of their life

For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating and as attractive as any you can find in a book. Many of the stories have to do with some kind of stereotype. You can speak with a refugee (难民), a soldier suffering from PTSD, a homeless person or a woman living with HIV. The Human Library encourages people to challenge their own long-held beliefs-to truly get to know, and learn from someone they might otherwise make a quick judgment about.

    According to its website, the Human Library is "a place where difficult questions are expected, appreciated and answered." It provides the opportunity for the community to share and understand the experiences of others in their community.

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Ronni Abergel, his brother Dany, and some colleagues hosted a four-day during a major Northern European festival, hoping to raise awareness about violence among youth. After the success of this event, Abergel founded the Human Library Organization, which has been growing ever since.

    Though there are a few permanent human libraries, most aren't places at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio.

The stories these "books" tell range from fascinating to heartbreaking and everything in between. And that's the very point of the organization--to prove that no person can be summed up in just one word. It seeks to show people that you truly can't judge a book by its cover—or by its title or label.

    Little black taxis, often run-down and falling apart from decades of use, have for a long time been a main feature of Cairo's chaotic urban landscape. But their days may be numbered, thanks to a new taxi replacement programme aimed at knocking out older, potentially unsafe vehicles.

    The government-sponsored action, launched earlier this year, allows drivers of taxis 20 years or older, mostly Fiats and Peugeots, to trade their cars for shiny new all-white ones at generous rates of financing. Drivers can choose between five different locally manufactured car models.

    According to officials, more than 11,000 brand new taxis, sporting trademark checked stripes on the sides, have already hit the streets of the capital, and they've been welcomed enthusiastically by passengers. Many people say that not only are the new taxis more comfortable, but they also make the streets of Cairo far more presentable. Furthermore, taxi fares have only increased by a small amount.

    The poor condition of most black and white taxis is almost legendary. Passengers often have to deal with windows and doors that do not open and close, and heavy, thick petrol gases. Air conditioning is unheard of. The new all-white taxis, meanwhile, are cleaner, more fuel-efficient and provide air conditioning on request. Furthermore, all the new taxis come equipped with functioning fare meters, which avoids arguments and sometimes fights with passengers!

    The government hopes to replace all of the capital's 40,000 elderly black cabs soon, but not everyone in Cairo will be happy to see them go. Hotel manager Ibrahim Al-Toukhy says that the old black cabs were weak and run-down, and maybe even a little dangerous, but they were part of the city, and part of Cairo's character.
