Showing results for "J" in Biological Sciences

When Stephen Bodio was a young boy in the early '50s, he saw an image in National Geographic that became forever etched in his mind: It was a photograph of a Kazakh nomad, dressed in a long coat and wearing a fur hat, holding a huge tame eagle on his fist. And a lifelong fascination with Central Asia was born.

In 1898, the British were building a railway line between Mombasa in Kenya and Uganda. At the Tsavo River in Kenya where a bridge needed to be built, the project was suddenly interrupted by two man-eating lions that targeted the camps of the workers. Over a period of nine months, the lions killed scores of people. These lions were deliberately hunting people, preferring humans over any other prey, and they seemed to have supernatural abilities in evading all attempts to stop them. Colonel J.H. Patterson, the chief engineer in charge of the project, finally managed to eliminate them.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.

Breakthroughs in genetics present us with a promise and a predicament. The promise is that we will soon be able to treat and prevent a host of debilitating diseases. The predicament is that our newfound genetic knowledge may enable us to manipulate our nature - to enhance our genetic traits and those of our children. Although most people find at least some forms of genetic engineering disquieting, it is not easy to articulate why.

Today's kids have adopted sedentary lifestyles filled with television, video games, and computer screens. But more and more, studies show that children need "rough and tumble" outdoor play in order to develop their sensory, motor, and executive functions. Disturbingly, a lack of movement has been shown to lead to a number of health and cognitive difficulties, such as attention deficit/hyperactivity disorder (ADHD), emotion regulation and sensory processing issues, and aggressiveness at school recess break.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

No feature of the mind is as important, controversial, and mysterious as intelligence. It is the epitome of brain function, and it has a powerful influence on success in life. Now in The Intelligent Brain, taught by one of the world’s foremost researchers on intelligence, Professor Richard J. Haier of the University of California, Irvine, you’ll trace the fascinating history of intelligence testing and its leading thinkers, as well as what brain imaging studies and the most recent research findings reveal about this most complex of human phenomena.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

Testosterone propels our drive for exploration and risk, for competition and creation, and even our survival. The effects of testosterone permeate the traditions, philosophy, and literature of every known culture - without it, the world would be a drastically different place. It also has a role in humanity's darker side, contributing to violence, hubris, poverty, crime, and selfishness. Recent revelations of the science of testosterone show that high levels will deplete compassion and generosity, and even reduce the affection we show our children.

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

Does your dog get sad when you leave for the day? Does your cat purr because she loves you? Do bears attack when they’re angry? You can’t very well ask them. In fact, scientists haven’t been able to reach a consensus on whether animals even have emotions like humans do, let alone how to study them. Yet studies of animal emotion are critical for understanding human emotion and mental illness. In The Nature of the Beast, pioneering neuroscientist David J. Anderson describes a new approach to solving this problem.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs' clinic to the present.

Human behavior is lopsided. When cradling a newborn child, most of us cradle the infant to the left. When posing for a portrait, we tend to put our left cheek forward. When kissing a lover, we tend to tilt our head to the right. Why is our behavior so lopsided and what does this teach us about our brains? How have humans always used this information to make our images more attractive and impactful? Can knowing how left-brain right-brain differences shape our opinions, tendencies, and attitudes help us make better choices in art, architecture, advertising, or even athletics?

Hidden in the names of English towns and villages, in copses, fields, lanes and hills, are the ghostly traces of birds conjuring powerful identities for people in ancient landscapes. What are their stories and secrets? How did people encounter birds over a thousand years ago? In The Cuckoo’s Lea, Michael J. Warren sets out on the trail of these ghosts. Captivated and guided by the secrets of place names, he finds their stories entangled with his own explorations of places through birds all across England.

Award-winning author and celebrated neurosurgeon Allan J. Hamilton, MD, combines his understanding of the human brain with nearly 30 years' experience training horses to offer wisdom on such universal themes as leadership, motivation, ambition, and humility. The results are showcased in more than 100 thoughtful essays that treat working with horses as a metaphor for personal, professional, and spiritual growth.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?
