Back then, most experts believed that differences in how girls and boys behave are mainly due to differences in how they were treated by their parents, teachers, and friends.It's hard to cling to that belief today. An avalanche of research over the past twenty years has shown that sex differences are more significant and profound than anybody guessed. Sex differences are real, biologically programmed, and important to how children are raised, disciplined, and educated. In Why Gender Matters, psychologist and family physician Dr. Leonard Sax leads parents through the mystifying world of gender differences by explaining the biologically different ways in which children think, feel, and act. He addresses a host of issues, including discipline, learning, risk taking, aggression, sex, and drugs, and shows how boys and girls react in predictable ways to different situations. For example, girls are born with more sensitive hearing than boys, and those differences increase as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely, boys who appear to be inattentive in class may just be sitting too far away to hear the teacher—especially if the teacher is female. Likewise, negative emotions are seated in an ancient structure of the brain called the amygdala. Girls develop an early connection between this area and the cerebral cortex, enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often literally cannot say.Dr. Sax offers fresh approaches to disciplining children, as well as gender-specific ways to help girls and boys avoid drugs and early sexual activity. He wants parents to understand and work with hardwired differences in children, but he also encourages them to push beyond gender-based stereotypes. A leading proponent of single-sex education, Dr. Sax points out specific instances where keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Despite the view of many educators and experts on child-rearing that sex differences should be ignored or overcome, parents and teachers would do better to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.

    This is the funny, poignant story of their two decades together.On Valentine's Day 1985, biologist Stacey O'Brien first met a four-day-old baby barn owl -- a fateful encounter that would turn into an astonishing 19-year saga. With nerve damage in one wing, the owlet's ability to fly was forever compromised, and he had no hope of surviving on his own in the wild. O'Brien, a young assistant in the owl laboratory at Caltech, was immediately smitten, promising to care for the helpless owlet and give him a permanent home. Wesley the Owl is the funny, poignant story of their dramatic two decades together. With both a tender heart and a scientist's eye, O'Brien studied Wesley's strange habits intensively and first-hand -- and provided a mice-only diet that required her to buy the rodents in bulk (28,000 over the owl's lifetime). As Wesley grew, she snapped photos of him at every stage like any proud parent, recording his life from a helpless ball of fuzz to a playful, clumsy adolescent to a gorgeous, gold-and-white, macho adult owl with a heart-shaped face and an outsize personality that belied his 18-inch stature. Stacey and Wesley's bond deepened as she discovered Wesley's individual personality, subtle emotions, and playful nature that could also turn fiercely loyal and protective -- though she could have done without Wesley's driving away her would-be human suitors! O'Brien also brings us inside the prestigious research community, a kind of scientific Hogwarts where resident owls sometimes flew freely from office to office and eccentric, brilliant scientists were extraordinarily committed to studying and helping animals; all of them were changed by the animal they loved. As O'Brien gets close to Wesley, she makes important discoveries about owl behavior, intelligence, and communication, coining the term "The Way of the Owl" to describe his inclinations: he did not tolerate lies, held her to her promises, and provided unconditional love, though he was not beyond an occasional sulk. When O'Brien develops her own life-threatening illness, the biologist who saved the life of a helpless baby bird is herself rescued from death by the insistent love and courage of this wild animal. Enhanced by wonderful photos, Wesley the Owl is a thoroughly engaging, heartwarming, often funny story of a complex, emotional, non-human being capable of reason, play, and, most important, love and loyalty. It is sure to be cherished by animal lovers everywhere.

    From spring and through a year in his home patch in Northern Ireland, Dara spent the seasons writing. These vivid, evocative and moving diary entries about his connection to wildlife and the way he sees the world are raw in their telling. "I was diagnosed with Asperger's/autism aged five ... By age seven I knew I was very different, I had got used to the isolation, my inability to break through into the world of talking about football or Minecraft was not tolerated. Then came the bullying. Nature became so much more than an escape; it became a life-support system." Diary of a Young Naturalist portrays Dara's intense connection to the natural world, and his perspective as a teenager juggling exams and friendships alongside a life of campaigning. "In writing this book," Dara explains, "I have experienced challenges but also felt incredible joy, wonder, curiosity and excitement. In sharing this journey my hope is that people of all generations will not only understand autism a little more but also appreciate a child's eye view on our delicate and changing biosphere."
