British Museum

    Mother Teresa was born in Yugoslavia on August 27th, 1910. She attended the government school near her home until she was eighteen. At that time, some doctors and nurses from Yugoslavia were working in India, and they often wrote to school about their work. She decided to join them one day.

    When she finished school, she went first to Britain. Then a year later she went to India, where she began to train to be a teacher. After training, she was sent to Calcutta, where she taught geography at a school and soon after she became headmistress. (女校长)

    However, although she loved teaching, in 1946 Mother Teresa left school and went to work in the poor parts of Calcutta. Later she trained to become a nurse in Panta, and then began her work helping the poor and comforting the dying in the streets of the city. Slowly others came to help her, and her work spread to other parts of India.

    Mother Teresa is now a well-known person. Many photos have been taken of her as she traveled the world to open new schools and hospitals in poor countries. In 1979, she was given the Nobel Peace Prize for the lifetime of love and service she has given to the poor.

    In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception（感知）of the food in front of us.

    Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual clues, like plate size and lighting, have been shown to affect portion size and consumption.

    A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them—in other words, how much they remembered eating.

    This disparity (新旧研究的差异）suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.

    "Hunger isn't controlled individually by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal," Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."

    These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones （荷尔蒙），depending on whether the shake's label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.

    What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.

    The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.

    When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).

    Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.

    But why are people so frightened about the idea of AI?

    Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al, and I think people should be really concerned about it. I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."

    Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.

    After a morning hike in the Saneum HealingForest,46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽),and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer“forest healing" (森林治愈);the firefighters all have posttraumatic stress disorder (创伤后应激障碍).

    Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.

    There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it.

    "We don't think of being outdoors as a way to increase happiness," says Nisbet."We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.

    So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.

Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.

    Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.

In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.
