    Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:

    A happier heart

    Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart.Studies have shown heart benefits from increased blood flow. These benefits are the result of coca's chemicals, which seem to prevent both cell damage and inflammation (炎症).

    Better blood pressure

    If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.

    Muscle magic

    Chocolate milk may help you recover after a hard workout (锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.

    Better for your skin

    German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women's skin was moister (滑润的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.

Brain gains

    It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain.

    Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

    Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.

    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    “Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says.  “Our system allows disabled people to communicate with external world and also to control devices.”

    The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

    Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

    Ongoing conflicts across the Middle East have prevented more than 13 million children from attending school, according to a report published by UNICEF, the United Nations Children's Fund.

    The report states that 40% of all children across the region are currently not receiving an education, which is a result of two consequences of violence: structural damage to schools and the displacement (转移) of populations, also called “forced migration.” Both issues result from the violence that has crossed the region in recent years. The report examines nine countries where a state of war has become the ordinary state. Across these countries, violence has made 8,500 schools unusable. In certain cases, communities have relied on school buildings to function as shelters for the displaced, with up to nine families living in a single classroom in former schools across Iraq.

    The report pays particularly close attention to Syria, where a bloody civil war has displaced at least nine million people since the war began in 2011. With the crisis (危机) now in its fifth year, basic public services, including education, inside Syria have been stretched (竭尽所能) to breaking point. Within the country, the quality and availability of education depends on whether a particular region is suffering violence.

    The report concludes with an earnest request to international policymakers to offer money and other resources to help ease the regional crisis. With more than 13 million children already driven from classrooms by conflict, the educational future of a generation of children are in the balance. This is destroying the future for an entire region.

    The latest study by the University of Florida has found that eating from smaller, less beautiful, and even paper plates will help prevent overeating. Eating with a fork instead of a spoon can help you lose weight, the researchers say. Much to their surprise, they find that putting mirrors in the dining room will also help reduce weight.

    The researchers asked 185 college students to choose a chocolate cake or a fruit salad, and evaluated the taste. Those who ate in a room with a mirror scored the taste of junk food much lower than those in a room without a mirror. But the taste of fruit salad remained the same in any case.

    Lead scientist, Dr. Ata Jami, says that a glance in the mirror tells people more than just about their physical appearance. It enables them to view themselves objectively and helps them to judge themselves and their behavior in the same way that they judge other people.

    The mirrors were found to push people to compare and match their own behavior with accepted social standards. The researchers believe it proves that people don't want to look in the mirror when they feel they are following the social standards. When they look in the mirror with mouths full of junk food, feelings of discomfort and failure can be increased. Therefore, the presence of the mirror lowers the taste of unhealthy food.

    However, researchers say this is only the case if people select the food they are eating, because they are responsible for that choice. The researchers suggest that mirrors be placed in dining rooms and other eating spaces, so that people will start eating more healthily.

    Emily Temple-Wood was 12 years old the first time she was bullied(欺凌) online. They left ugly comments on her Wikipedia and Facebook pages about her looks "that would make my mother's hair curl." says Temple-Wood, now 22 and in medical school. The reason? "I was a woman on the Internet," she said.

    Over the years, she considered how she might take revenge(复仇). Then, as a freshman in college, it hit her: "What do misogynists(men who hate women) hate most?" she asked herself. "Women who are productive!" Her solution: For every rude comment she received, Temple-Wood would post a biography(传记) of a woman scientist, and thus, in 2012, Wiki Project Women Scientists was born. She wrote about her heroes, like Barbara McClintock, who received the 1983 Nobel Prize in Physiology or Medicine, and Caroline Still Anderson, one of the first African American women to become a doctor in the United States, in the late 1800s. With help from other women, many of them scientists who have also been bullied online, Temple-Wood has published hundreds of these biographies and women of all ages have taken notice.

    "When I was a kid, I could count the number of women scientists I knew about on one hand," wrote Siko Bouterse, who used to work for the Wikimedia Foundation. "But our daughters have the chance to get much more knowledge about scientists who look like them because of Emily.

    The ugly comments still come, says Temple-Wood. Being a strong woman online is not easy. "We all have days when we break down and need to have a glass of wine," she says. "I tell people who are being bullied that it's OK to be sad. But now you need to find a productive way to take revenge."

Walk in London's cobblestoned streets, cross centuries-old bridges and wander through covered markets — before the morning drizzle (毛毛雨) has given way to afternoon sun, history will become alive before you. The city's old buildings, black taxis and red double-decker buses all have long and complicated stories that are deeply rooted in London's traditions. So do fish and chips. Apart from being a fast-food favourite, fish and chips are also typically served as a Friday meal, in schools for lunch and at home for dinner. Former British prime minister Winston Churchill famously called fish and chips "the good companions".

More than 229 million portions of white fish fillets are sold each year in England, each one coated in a light batter (面糊) and deep-fried, and served alongside fat fried slices of potatoes. For many English people, fish and chips are best served wrapped in newspapers and wolfed down with a combination of a wooden fork and greasy fingers, preferably seaside.

Most historians agree that it was in London, not on the coast, that the first fish and chip shop opened its doors. It was here too that the city's working class pushed the dish into popular cooking culture. And it is in London that one of the oldest surviving chippies still stands today.

This is an understandable source of despair for nutritionists: Fish and chips may contain an abundance of vitamins and minerals, but both main ingredients are also deep-fried in oil that often contains unhealthy saturated fats. For all its traditional popularity, however, according to a 2016 study by the U. K. Department for Environment, Food and Rural Affairs, fish and chips consumption has lost significant market share in recent years to other takeaway items such as pizza and kebabs.
