Development of the Cardiac Conduction System

The most important investigation of genetic science since The Selfish Gene, from the author of the critically acclaimed and best-selling The Red Queen and The Origins of Virtue.The genome is our 100,000 or so genes. The genome is the collective recipe for the building and running of the human body. These 100,000 genes are sited across 23 pairs of chromosomes. Genome, a book of about 100,000 words, is divided into 23 chapters, a chapter for each chromosome. The first chromosome, for example, contains our oldest genes, genes which we have in common with plants.By looking at our genes we can see the story of our evolution, what makes us individual, how our sexuality is determined, how we acquire language, why we are vunerable to certain diseases, how mind has arisen. Genome also argues for the genetic foundations of free will. While many believe that genetics proves biological determinism, Ridley will show that in fact free will is itself in the genes. Everything that makes us human can be read in our genes. Early in the next century we will have determined the function of every one of these 100,000 genes.

Based on exciting discoveries in mathematics, genetics, psychology and sociology, ‘Connected’ is an innovative and fascinating exploration of how social networks operate.Think it’s all about who you know? It is. But not the way you think.Turns out your colleague’s husband’s sister can make you fat, even if you don’t know her. And a happy friend is more relevant to your happiness than a bigger income.Our connections – our friends, their friends, and even their friends’ friends – have an astonishing power to influence everything from what we eat to who we sleep with. And we, in turn, influence others. Our actions can change the behaviours, the beliefs, and even the basic health of people we’ve never met.In this brilliantly original and effortlessly engaging exploration of how much we truly influence one another, pre-eminent social scientists Nicholas Christakis and James Fowler explain why obesity is contagious, why the rich get richer, even how we find and choose our partners. Intriguing and entertaining, with revelatory implications for everything from our notion of the individual to ideas about health care policy, “Connected” will change the way you think about every aspect of your life, and how you live it.

How could a relatively simple chemical code give rise to the complexity of a human being? How could our human genome have evolved? And how does it actually work?Over the past 50 years we have deciphered the inner workings of the human genome. From the basic structure of DNA through to the complete sequence of the code, what first appeared to be simple is actually a complex and beautiful three-dimensional world that makes each of us who we are.In The Mysterious World of the Human Genome acclaimed science writer Frank Ryan leads us through the most exciting scientific discoveries of the last 50 years, revealing how this science has unlocked the cure of some genetic diseases, developed the use of DNA in forensic science and paternity testing, helped us trace our ancestors and provided a definitive map for the movement of humans out of Africa. This scientific journey has had a profound impact on our understanding of the evolution of life itself, through the role of the most ancient of organisms in our basic biology all the way to the revelation that our most recent ancestor, Homo neanderthalensis, lives on in many of us.In the ever more complicated world of the human genome, this is the first book to explain how the human genome actually works as a whole and how that knowledge will have a profound effect on our understanding of where we have come from and where we are likely to be going in the future.

Our use of light at night is negatively affecting the natural world in ways we’re barely beginning to study. Meanwhile, our physical, psychological, and spiritual health are significantly influenced by darkness or a lack thereof; it’s not a matter of using light at night or not, but rather when and where, how and how much.We live awash in artificial light. Since the 1930s its increase has been gradual enough that it would be easy to imagine our nights are as dark, or nearly so, as they ever were. But today some three-quarters of Europeans and Americans no longer experience real night and can’t imagine real darkness—and nearly all of us live in areas considered polluted by light.In ways we’ve long understood, in others we’re just beginning understand, night’s natural darkness has always been invaluable for our spiritual health and the health of the natural world, and every living creature suffers from its loss.In Geography of Night, Paul Bogart investigates what we mean when we talk about the different shades of darkness, about what we’ve lost, what we still have, what we might regain. He travels from our brightest nights to our darkest, from the intensely-lit cities where public lighting as we know it began, to the sites where real darkness might still remain. Encountering scientists, physicians, activists and writers, Bogart discusses how our use of light at night is negatively affecting the natural world in ways we’re barely beginning to study; how human physical, psychological, and spiritual health are significantly influenced by darkness or a lack thereof; and how it’s not a matter of using light at night or not, but rather when and where, how and how much.A beautiful invocation of our constant companion, the night, which returns every day of our lives, this book reminds us of the power and mystery of the dark.
