When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked.“Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I go to fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it.“That's just for you，” he said.“You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Bees and other pollinators（传粉者）  use smells to track down fresh flowers. Air pollutants can weaken those scents（气味）.  Scientists had worried this might make it harder for some pollinators to find a meal.

    Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat（栖息地）can be one factor. Diseases and exposure to poisonous chemicals also count.

    Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.

    Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive（蜂巢）or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.

    In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air.  Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.

    Worse still, air pollution might do more than just weaken scent plumes（气味烟云）．Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.

    That's certainly Fuentes' concern.  So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.

    Most people will answer a ringing phone. Usually you don't know who is phoning or how urgent their business is, so a ringing phone is difficult to ignore. In one experiment, a researcher wrote down the numbers of several public phones in stations and airports. Then he called the numbers. Someone nearly always answered. When he asked why, people usually said, “Because it rang.”

A few years ago in New Jersey, a man with a rifle killed 13 people. Armed police surrounded his house but he refused to come out. A reporter found out the phone number of the house and called. The man put down his rifle and answered the phone. “What do you want?” he said, “I'm really busy right now.”

    Imagine you're at work and the phone is ringing in someone else's office. Do you answer it or not? In one survey on telephone use, 51% of participants told researches that they did. We can't ignore the phone and for the reason, it forces its way into our lives. It interrupts what we are doing and on top of that, the caller is often someone we don't really want to talk to. However, in the survey, 58% said they never took the phone off the hook, and 67% didn't mind if someone called during a television programme. For 44% it wasn't a problem if someone rang during a meal, while only 28% were annoyed or upset. If someone phoned in the middle of the night, 40% told researchers that they got nervous or frightened, while around 30% got angry.

    Of course, when someone is really annoying, you can choose to hang up on him/her. This is in fact one of the rudest things you can do on the phone, but 79% said they were prepared to do it in some cases. Only 6% told researchers they never hung up on people.

    Meet the amazing Eliot Schrefer, and see why we're big fans!

    Scope: Why do you write stories about animals?

    Eliot: I've always been excited by animal stories. When I was young, I liked reading about animals because they seemed like they needed help, and they were also voiceless.

    Scope: Where did you get the idea for Animal Distress Calls?

    Eliot: Many years ago, I had a friend who worked as a doctor at the Bronx Zoo. One evening he invited me to see the zoo after hours. Wandering that still, dark zoo was haunting. I was imagining adventures with big wild animals, but only the wolves were awake. Then he took me into the clinic, where I met a sick bird. That nighttime visit clearly had a big impact on this story.

    Scope: Why did you leave Josie's fate ambiguous in the story Animal Distress Calls?

    Eliot: So many of us have known a creature, human or nonhuman, who's been suffering. Sometimes everything gets better, and sometimes it doesn't. That doesn't change the important, compassionate act of caring. I didn't want the story to become about the outcome of Josie's illness. I wanted it to be about the sympathy Josie and Julia share for each other.

    Scope: Have you had a personal experience with an animal that changed you?

    Eliot: I had a moment during research for my ape novels when I was staying at a bonobo sanctuary in Congo. I'd have breakfast with Oshwe, a young bonobo who was too little to eat with the rest of the group. Sitting with him for a few hours each morning, I helped make sure that he finished his meal and got the nutrition he needed—but it also felt like a gift he was giving me. Oh, I remember thinking, you're spending this precious morning time with me!

    In 1994 I wrote a letter. I stuck it in an envelope, put it away and completely forgot about it. It wasn't until we moved into our new home in 2006 that I found it again. It was addressed to me with explicit instructions not to open until my birthday 2005. It was now 2006 so I decided to open it. This is what it said: Dear Sherri.

    By the time you read this you will be 30. At the age of 18 I had so many hopes and dreams about where you'd be, what you'd be doing and with whom you'd spend your life with.

    Right now I hope that you have traveled and seen everything you've always wanted to, both in Canada and overseas, and maybe even settled down somewhere in Australia doing some research in the field of biology (genetics).I hope you're married to the man of your dreams. The man of mine is Gwynn. He is originally from South Africa (another place I wish to visit).

    However, if things don't go according to plan for you, I wish you all the love, happiness and joy in the world and don't settle for anything less than the best since that is absolutely what you deserve.

    Live long, be happy and live life to it's fullest.

    Love Sherri "18"

    When I read this for the first time since writing it I was floored. Even now having dug this up again another 4 years later I still can't help but think this is really cool. So much of what I wanted for myself has materialized. I did travel to a few more places in Canada although I haven't seen everything I'd like to.

    I did marry the man of my dreams and yes he still is my one and only. I lived in Australia for nearly 4 years, I had a career in Biology in the field of genetics for 10 years. I have two lovely kids I have not one dog but two dogs. Gwynn is a computer programmer.

    I suppose these were things that I really did want. Having never strayed too far from home overseas travel was a huge deal. Having never been away from my family moving to Australia for several years was an huge decision. I find it fascinating how the dreams of a young and naive little girl can become a grown woman's reality.

    How about writing a letter now to yourself in, say, 10 years from now? It's an interesting experiment.

    We talk continuously about how to make children more "resilient (有恢复力的)"，but whatever we're doing, it's not working. Rates of anxiety disorders and depression are rising rapidly among teenagers. What are we doing wrong?

    Nassim Taleb invented the word "antifragile" and used it to describe a small but very important class of systems that gain from shocks, challenges, and disorder. The immune (免疫的) system is one of them: it requires exposure to certain kinds of bacteria and potential allergens (过敏原) in childhood in order to develop to its full ability.

    Children's social and emotional abilities are as antifragile as their immune systems. If we overprotect kids and keep them "safe" from unpleasant social situations and negative emotions, we deprive (剥夺) them of the challenges and opportunities for self-building they need to grow strong. Such children are likely to suffer more when exposed later to other unpleasant but ordinary life events, such as teasing and social rejection.

    It's not the kids' fault. In the UK, as in the US, parents became much more fearful in the1980s and 1990s as cable TV and later the Internet exposed everyone, more and more, to those rare occurrences of crimes and accidents that now occur less and less. Outdoor play and independent mobility went down; screen time and adult-monitored activities went up.

    Yet free play in which kids work out their own rules of engagement, take small risks, and learn to master small dangers turns out to be vital for the development of adult social and even physical competence. Depriving them of free play prevents their social-emotional growth. Norwegian play researchers Ellen Sandseter and Leif Kennair warned: "We may observe an increased anxiety or mental disorders in society if children are forbidden from participating in age adequate risky play."

    They wrote those words in 2011. Over the following few years, their prediction came true. Kids born after 1994 are suffering from much higher rates of anxiety disorders and depression than did the previous generation. Besides, there is also a rise in the rate at which teenage girls are admitted to hospital for deliberately harming themselves.

    What can we do to change these trends? How can we raise kids strong enough to handle the ordinary and extraordinary challenges of life? We can't guarantee that giving primary school children more independence today will bring down the rate of teenage suicide tomorrow. The links between childhood overprotection and teenage mental illness are suggestive but not clear-cut. Yet there are good reasons to suspect that by depriving our naturally antifragile kids of the wide range of experiences they need to become strong, we are systematically preventing their growth. We should let go­and let them grow.
