Carl Zimmer

Carl Zimmer presents a history of our understanding of heredity in this sweeping, resonating overview of a force that shaped human society--a force set to shape our future even more radically. She Has Her Mother's Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities. . . . But, Zimmer writes, "Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are--our appearance, our height, our penchants--in inconceivably subtle ways." Heredity isn't just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors--using a word that once referred to kingdoms and estates--but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer's lucid exposition and storytelling, this resounding tour de force delivers it. Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world's best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.

In this unprecedented history of a scientific revolution, award-winning author and journalist Carl Zimmer tells the definitive story of the dawn of the age of the brain and modern consciousness. Told here for the first time, the dramatic tale of how the secrets of the brain were discovered in seventeenth-century England unfolds against a turbulent backdrop of civil war, the Great Fire of London, and plague. At the beginning of that chaotic century, no one knew how the brain worked or even what it looked like intact. But by the century's close, even the most common conceptions and dominant philosophies had been completely overturned, supplanted by a radical new vision of man, God, and the universe. Presiding over the rise of this new scientific paradigm was the founder of modern neurology, Thomas Willis, a fascinating, sympathetic, even heroic figure at the center of an extraordinary group of scientists and philosophers known as the Oxford circle. Chronicled here in vivid detail are their groundbreaking revelations and the often gory experiments that first enshrined the brain as the physical seat of intelligence -- and the seat of the human soul. Soul Made Flesh conveys a contagious appreciation for the brain, its structure, and its many marvelous functions, and the implications for human identity, mind, and morality.

• Within days of being born, we are infected with billions of E. coli. They will inhabit each and every one of us until we die. E. coli is notorious for making people gravely ill, but engineered strains of the bacteria save millions of lives each year. • Despite its microscopic size, E.coli contains more than four thousand genes that operate a staggeringly sophisticated network of millions of molecules. • Scientists are rebuilding E. coli from the ground up, redefining our understanding of life on Earth. In the tradition of classics like Lewis Thomas's Lives of a Cell , Carl Zimmer has written a fascinating and utterly accessible investigation of what it means to be alive. Zimmer traces E. coli 's remarkable history, showing how scientists used it to discover how genes work and then to launch the entire biotechnology industry. While some strains of E. coli grab headlines by causing deadly diseases, scientists are retooling the bacteria to produce everything from human insulin to jet fuel. Microcosm is the story of the one species on Earth that science knows best of all. It's also a story of life itself--of its rules, its mysteries, and its future.
