As a boy, Charles Robert Darwin(达尔文) collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.

    His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin's interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin's great life.

    As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.

    Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin's great book “On the Origin of Species by Means of Natural Selection”(《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.

    Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.

    On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country's father of space technology and king of rocketry”.

    Qian was born in 1911 in Hangzhou. He left for the United States after winning a scholarship to graduate school in 1936. He studied at the Massachusetts Institute of Technology and later at the California Institute of Technology.

    Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics（航空学) before returning to China in 1955.

    After he returned, Qian set up the first missile（导弹）and rocket research institute（学院) of China. The institute later helped start Chinese space program. He led the development of China's first nuclear-armed ballistic missile (弹道导弹) and worked on its first satellite.

    He retired in the year before Chinese manned space program was launched in 1992. But his research formed the basis（形成基础）for the Long March CZ -2F rocket that carried astronaut Yang Liwei into orbit in 2003.

    In August, 2009, Chinese Premier Wen Jiabao visited Qian and praised him for devoting his life to Chinese defense technologies. Qian told him, “I'm trying to live to be 100 years old”.

    “There's a mother in PICU (儿童重症监护病房) who wants to talk about a kit she received.” the nurse told me. “Something about it made her cry.”

    I've been a child-life specialist at the Cleveland Clinic Children's Hospital since 2000. I help families understand diagnoses and treatment plans and manage the ups and downs that come with caring for a sick child. Tough talks with parents are part of the job, it still makes me feel nervous.

    The kits the nurse was talking about were something I had recently introduced to the hospital: Comfort Kits from Guideposts. They were supposed to make a child's experience here easier, not upsetting.

    When I came across the kits at a conference, I fell in love with them. A treasure box of items designed not only to entertain kids, but to comfort and inspire them. There's a coloring book, a stress ball, a CD of relaxing music, a hairy star named Sparkle, a journal and much more. I really believed these kits would help kids. I wished I hadn't been mistaken.

    At the patient's room in PICU I saw a little girl, sleeping soundly, surrounded by tubes and machines. My eyes met her mother's. The kit was open on her lap and tears were running down her cheeks.

    “I'm Shannon. I manage the Child Life Department.” I said. “I'm sorry if the kit upset you. It's a new item…”

    The mother shook her head. “This has been one of the worst days of my life. I felt so scared and alone. Then I was handed this box. I know it's for my daughter, but it's just the comfort I needed. I wanted to say thank you.”

    With that I knew Comfort Kits belonged here. We've been using them for almost three years now. Each child who's admitted to the hospital receives one. Every day I see kids coloring, journaling, playing with Sparkle.

    But as this mom showed me Comfort Kits aren't just for kids. The hope they bring, which can be in short supply in hospitals sometimes, is felt by the whole family.

    Many people may not find the idea of visiting Beijing's Forbidden City just to see its cultural relics(遗迹)very exciting. But what if you got to see deer there too? That certainly sounds like a better day out.

    Nine deer were introduced into the Forbidden City, also known as the Palace Museum, on Sept. 26 and would make it their home until February. The beautiful animals are part of an exhibition on deer-related relics, including furniture, clothes and artworks. In ancient China, deer patterns(图案)could be seen on lots of items since lu—deer—were considered to be a lucky animal because the Chinese word shares the pronunciation(发音)of the character that means “official salary(俸禄)”.

    The deer in the Palace Museum are not only to be part of the exhibition, but also to act as ambassadors(大使)to attract visitors. “It's a better way to bring cultural relics closer to the people,”explained Wang Yamin, a deputy director at the Museum, according to ChinaDaily.

    Turning itself into a zoo is the latest effort that the museum has made at introducing academic(学术的)art to ordinary people.

    In 2014, for example, the museum's online store started to offer products such as T-shirts featuring the pattern of an emperor's coat, and earphones looking like the necklaces worn by ancient officials. These products soon gained popularity on social media because they allowed people to wear a piece of history.

    Two years later, the TV series MastersintheForbiddenCity(《我在故宫修文物》)lifted the mysterious veil(面纱)on the experts who work in the museum—people whose job is to repair the relics within it. And while many of us may have imagined these workers to be old and boring, they're actually quite young and interesting. Some are even in their 20s. They lead a peaceful career, although it can sometimes be dull. Workers aren't allowed to wear any make-up or do their nails(指甲)because the chemicals(化学物质)may damage the relics they're working on, for example.

    Little by little, the Palace Museum is shaking off the stereotypes(刻板印象)of being an old-fashioned academic institution. As Shan Jixiang, the museum's director, once said, “Academic research is not alien from the public's interest. We'd like to make visiting the museum a part of people's daily lives. ”

    It looks like the Forbidden City isn't so forbidden after all.

    We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.

    45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.

    " We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify."

    The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.

    Warm-blooded animals aren't immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.

    This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.

    The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.
