Harper Lee, whose 1961 novel To Kill a Mockingbird on the racial troubles of the American deep south, has died at the age of 89.

    Until last year, Lee had been something of a one-book literary legend. To kill a Mockingbird sold more than 40 million copies around the world and earned her a Pulitzer prize, remaining a towering presence in American literature. Another novel, Go Set A Watchman, was controversially published in July 2015 as a “sequel” to Mockingbird, though it was later confirmed to be Mockingbird's first draft.

    But from the moment Mockingbird was published to almost instant success, the author consistently avoided public attention. Lee had lived for several years in a nursing home near the house in which she had grown up in Monroeville, Alabama—the setting for Maycomb of her famous book. Her neighbor for 40 years, Sue Sellers, said, “She was such a private person. All she wanted was privacy, but she didn't get much. There was always somebody following her around.”

    James Naughtie, BBC Books Editor, commented on the novels of Harper Lee: “I think she stands, particularly among American readers, as someone who shone a light into a very dark place. She was writing at a time when people were beginning to lift the lid on everything in the South which they'd chosen not to understand. That all changed in the 1960s. So I think her status for writing that book in its extraordinarily direct way will remain.

    Neuroscientists have explained the risky, aggressive or just plain baffling behavior of teenagers as the product of a brain that is somehow compromised. Groundbreaking research in the past 10 years, however, shows that this view is wrong. The teen brain is not defective. It is not a half-baked adult brain, either. It has been forged by evolution to function differently from that of a child or an adult.

    The most important of the teen brain's features is its ability to change in response to the environment by modifying the communication networks that connect brain regions. It allows teenagers to make enormous progress in thinking and socialization. But the change also makes them sensitive to dangerous behavior and serious mental disorders.

    The most recent studies indicate that the riskiest behaviors arise from a mismatch between the maturation of networks in the limbic system(边缘系统), which drives emotions at adolescence, and the maturation of networks in the prefrontal cortex（前额皮质）, which occurs later and promotes sound judgment and the control of impulses. Indeed, we now know that one's prefrontal cortex continues to change noticeably until his 20s. And yet adolescence seems to be starting earlier, extending the “mismatch years.”

    The plasticity of networks linking brain regions—and not the growth of those regions, as previously thought—is key to eventually behaving like an adult. Understanding that, and knowing that a widening gap between the development of emotional and judgment networks is happening in young people today, can help parents, teachers, counselors and teenagers themselves. People will better see that behavior such as risk-taking and turning away from parents and toward peers are not signs of cognitive or emotional problems. They are a natural result of brain development, a normal part of adolescents learning how to negotiate with a complex world.

    The same understanding can also help adults decide when to intervene. A 15-year-old girl's departure from her parents' tastes in clothing, music or politics may be a source of anxiety for Mom and Dad but does not indicate mental illness. A 16-year-old boy's tendency to skateboard without a helmet or to accept risky dares from friends is not unimportant but is more likely a sign of short-range thinking and peer pressure than a desire to hurt himself. Knowing more about the unique teen brain will help all of us learn how to separate unusual behavior that is age-appropriate from that which might indicate illness. Such awareness could help society reduce the rates of teen addiction, motor vehicle accidents and depression.

    Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told again, is as necessary as putting gasoline in the family car before starting a trip.

    But for many people the thought of food as first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures are available, the number of people who didn't have breakfast increased by 33 percent-from 8.8 million to 11.7 million-according to the Chicago-based Market Research Corporation of America.

    For those who feel pain or guilt about not earing breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with not taking breakfast. “Going without breakfast does not affect performance,” said Arnold E. Bender, former professor of nutrition（营养）at Queen Elizabeth College in London, “nor doegiving people breakfast improve performance.”

    Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. “The literature,” says one researcher, Dr. Ernesto Pollitt at the University of Texas, “is poor.”

    In the past five years, Instagram has taken off faster than anyone would have ever expected. It has become more than just a social media platform; it has become a community. With this community of over 800 million people, there are two distinct sides when it comes to diet culture and weight-loss programs. These two sides are body positivity and body manipulation(操纵）

    I have run a food and lifestyle blog/Instagram for over two years, and I have experienced both of these sides shown through Instagram. I have followed accounts (账户) that have been about strictly counting their calories, and have looked at other people carefully for their food habits

    On the other side of this, the only accounts that I'll follow now are people who support intuitive eating, never calorie counting, and make sure to remind people that their weight is the least interesting thing. They try to remind people that food is fuel, rather than something that will make them lose or gain weight. This side of

    Instagram is what helps people suffering from eating disorders, rather than fueling them.

    The rise of Instagram also led to the rise of what we called" Instagram models. These people have a lot of fans and a very pleasant page on Instagram. Basically, this isn't a bad thing. Humans are attracted to attractive people. Where this does go wrong is when weight-loss programs, weight-loss products, and other people supporting different types of diets get in touch with these people and offer them pay to get their message across.

    We also run into issues with how the public thinks of and admires these people for only their bodies. Not only is it bad for the self-respect of the people viewing the account, but also for the mental health of the person running the Instagram account.

    The people that promote these products are usually attractive, with what we would consider "the perfect body and the products are almost always diet related in some way, which makes consumers believe that in order to reach this ideal body they must use this product.
