“Success begins with belief and ends with doubt.”—Larina Kase

    I remember reading through a book and the author was writing about being a reverse paranoid. In that particular section he mentions how he has a belief that the world he's living in is out to give him everything he absolutely wants and desires.

    There are times when I think to myself，“Wow，the world is out to get me and make me miserable.” Then I thought，why can't I believe that the world is out to make me a better conversationalist. Then I started adapting to the belief of the reverse paranoia.

    When I started talking to people，I truly believed that I was the most interesting person in the room. I believed that everything I said added value to the conversation. I believed that people stayed behind and chatted with me because they found me charismatic.

    As a matter of fact, for about five months I wrote down on my bathroom mirror the following affirmation：“People love me and respect me. It is a privilege to talk to me. People find me interesting and charming and always want to get to know me better！”

    I would say the affirmation after I brushed my teeth. And I would continue to say it until I felt completely great about myself. There were days that I just wouldn't feel like saying it，because it would feel like a lie to me. But that's the trouble，like the quote says，success ends when there's doubt. And that's why I continued until I had no doubt in my mind.

    Then strange things happened，I noticed that people did find me more interesting，and that I gained more confidence in talking with people. I was more assertive(坚定自信的) at work. I was able to control politics and gossip at work to minimal levels，and became a much better manager，and developed better customer relations to the point that sales were up by 20% compared to the year before，on my best month sales were up by 39%，and this was a year that a recession was happening.

    Getting paid to stay in bed all day sounds pretty good. But what if someone offered you $23,000 to stay in bed for two months? That's the deal that are search team is offering to 24 volunteers.

    Researchers are looking for volunteers to help them study the influences of weightlessness on the human body by spending 60 days lying down. Lying in bed isn't exactly the same as being weightless, but the influences on the human body are similar.

    When astronauts spend a long time in an environment with no gravity(重力), like the International Space Station (ISS),their bodies are affected in many ways. After a couple of months on the ISS, astronauts' hearts don't beat as hard. Their muscles（肌肉）become weaker because they no longer have to work against gravity. Their bones may break more easily. There may also be changes in the astronauts' sleep habits.

    Dr. Arnaud Beck, the researcher in charge of the study, said his goal is to measure the influences of weightlessness, and also to find ways to prevent problems. The study will take 88 days altogether. During the first two weeks the volunteers will be tested to establish(确定) their levels of fitness. Then they will spend 60 days lying in bed with their heads slightly lower than their bodies. They will have to do everything while lying down, including brushing their teeth and going to the bathroom. Dr. Beck said the rule is that they must have at least one shoulder touching the bed at all times. Half of the volunteers in the study will be taking capsules(胶囊) containing special food supplements（增补物）several times a day to see if they help reduce the health problems caused by weightlessness. The last two weeks of the study will be spent trying to let the volunteers recover. Volunteers must be men between the ages of 20 and 45 who are in perfect health. They must be non-smokers.

    The study will take place from September 1^st to November. The first two days are the time for volunteers to sign in.

    Think plants are just boring green things that you use for food and decoration? Think again! Plants are able to do some pretty awesome things that you're probably totally unaware of.

    Researchers have discovered that plants have the ability to communicate with an underground network made up of fungus (真菌) , which serves the plants in many ways. Tomato plants use the fungus web to warn each other of their own unhealthy conditions. Trees connected through the fungus network could move nutrients (养分) to and from each other. It is believed that larger trees move nutrients to smaller ones to help them to survive.

    Not only that, but they can also damage unwelcome plants by spreading poisonous chemicals through the fungus. It sounds like the plant world had the Internet before we did.

    Some plants have a rather impressive line of defense against being eaten. When sensing they are being swallowed, they give off a chemical into the air that attracts the insect's natural enemy. The enemy attacks the bug, thus saving the plants. This is basically the plant kingdom version of getting your older brother to beat up that kid who steals your lunch money.

    You might be aware that humans and animals have an internal clock. But did you know that plants also have this clock? This means they can prepare for certain times of day just like we do. Is it because they can react to light at sunrise? In a study, scientists found that plants use the sugars they produce to keep time, which help to regulate the genes responsible for the plant's own internal clock. So, in a sense, wake up with petunias (矮牵牛) is just as valid as ―wake up with the chickens.

    Nature is full of surprises. So for those of you who didn't know the wonders of plants, now you do.

    A so-called “smart drug” intended to improve people's cognitive (认知的) function to protect the brain from altitude sickness.

    Visiting high-altitude sites for work, spot, religious pilgrimages and military can result in cognitive effects, including memory loss and attention difficulties. There's little you can do to prevent these symptoms except acclimatize -but this takes time and doesn't always work. A drug called oxiracetam might be the answer.

    ShengLi Hu at the Third Military Medical University, Chongqing, China and her colleagues studied the performance of male military personnel at altitude. All lived in towns around 1,800 meters above sea level, During the study, they spent eight days at this altitude and then climbed for three days to reach 4,000 meters, where they stayed for up to a month.

    Twenty participants took oxriacetam three times a day for the first 15 days of the study, while another 20 received no intervention. The man did tests of attention and memory at the start and end of the study and 20 days in, by which time they had been at 4,000 meters for nine days.

    While all the participants experienced a drop in cognitive ability at 4,00 meters, those who took oxiracetam showed a much smaller drop than the control group.

    The team found that at high altitude the brain stem, which plays a critical role in supporting basic living functions, received blood at the expense of areas responsible for more advanced cognitive functions. But in people who took oxiracetam, blood flowing throughout the brain rose, thus offering more oxygen to these areas. This may be how the drug seems to lessen cognitive problems like with low oxygen.

    It isn't yet known whether diverting blood in this way could have negative effects in the long run. "The results are striking and imply that oxiracetam may be beneficial for helping to relieve cognitive ability decline caused by altitude." says Timothy Hales at the University of Dundee, UK.

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.

    Kakano means "seed" in Māori. For Jade Temepara, a Māori woman who was crowned New Zealand's Gardener of the Year in 2012, though, it means a lot more. Temepara owns Kākano, a Māori restaurant and cooking school in Christchurch, on New Zealand's South Island.

    Even a first-time tourist to New Zealand will notice the presence of the Māori culture and language everywhere. Now, so many non-Māori young people learn the language — a trend that picked up after the passage of the Māori Language Act in 1987 — that it's not unusual to hear teens and twenty somethings of European descent in Auckland asking their friends if they want to hang out and get some kai (food) later. That's a striking contrast from several generations ago, when New Zealand law banned Māori in schools, either in written or spoken form.

    While Temepara was happy to see the Māori language make a comeback, there were still parts of her native culture that were less present in New Zealand's daily life. She felt that too few Māoris of her generation were trained in their culture's traditional cooking methods and native ingredients (原料). That's when Temepara came up with the idea of launching a cooking education program that would go into Māori schools and other community gathering places to teach classes in traditional Māori cooking and food preparation.

    The idea was so successful that it eventually led to a brick-and-mortar cafe and shop in central Christchurch. There, Temepara trades in traditional kai — look for cold smoked mussels, karengo (a native seaweed), Manuka honey and a native variety of sweet potato called kumara.

    Although many of the ingredients grow wild in New Zealand, that doesn't mean just anybody can harvest them.

    "The Māori subtribe Katti Menguai are the only ones that are allowed to have some, if they come from a lineage of chiefs. It is by bloodline only. You can't even be invited. If you're not blood, that's it, you can't go. My family is of that lineage. And so, traditionally we would harvest the birds." This is both a tribal (部落的) practice and an accepted national law.
