Book excerpt: From the author of the acclaimed The Epigenetics Revolution (‘A book that would have had Darwin swooning’ – Guardian) comes another thrilling exploration of the cutting edge of human science. For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions – 98% of the human genome – were dismissed as ‘junk’. But in recent years researchers have discovered that variations in this ‘junk’ DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them. Nessa Carey explores, for the first time for a general audience, the incredible story behind a controversy that has generated unusually vituperative public exchanges between scientists. She shows how junk DNA plays an important role in areas as diverse as genetic diseases, viral infections, sex determination in mammals, human biological complexity, disease treatments, even evolution itself – and reveals how we are only now truly unlocking its secrets, more than half a century after Crick and Watson won their Nobel prize for the discovery of the structure of DNA in 1962.

Available in PDF, EPUB and Kindle. Book excerpt: After World War II, the US Atomic Energy Commission (AEC) began mass-producing radioisotopes, sending out nearly 64,000 shipments of radioactive materials to scientists and physicians by 1955. Even as the atomic bomb became the focus of Cold War anxiety, radioisotopes represented the government’s efforts to harness the power of the atom for peace—advancing medicine, domestic energy, and foreign relations. In Life Atomic, Angela N. H. Creager tells the story of how these radioisotopes, which were simultaneously scientific tools and political icons, transformed biomedicine and ecology. Government-produced radioisotopes provided physicians with new tools for diagnosis and therapy, specifically cancer therapy, and enabled biologists to trace molecular transformations. Yet the government’s attempt to present radioisotopes as marvelous dividends of the atomic age was undercut in the 1950s by the fallout debates, as scientists and citizens recognized the hazards of low-level radiation. Creager reveals that growing consciousness of the danger of radioactivity did not reduce the demand for radioisotopes at hospitals and laboratories, but it did change their popular representation from a therapeutic agent to an environmental poison. She then demonstrates how, by the late twentieth century, public fear of radioactivity overshadowed any appreciation of the positive consequences of the AEC’s provision of radioisotopes for research and medicine.

Available in PDF, EPUB and Kindle. Book excerpt: In 1965, French microbiologist André Lwoff was awarded the Nobel Prize in Physiology or Medicine for his work on lysogeny—one of the two types of viral life cycles—which resolved a contentious debate among scientists about the nature of viruses. A Tale of Two Viruses is the first study of medical virology to compare the history of two groups of medically important viruses—bacteriophages, which infect bacteria, and sarcoma agents, which cause cancer—and the importance of Lwoff’s discovery to our modern understanding of what a virus is. Although these two groups of viruses may at first glance appear to have little in common, they share uniquely parallel histories. The lysogenic cycle, unlike the lytic, enables viruses to replicate in the host cell without destroying it and to remain dormant in a cell’s genetic material indefinitely, or until induced by UV radiation. But until Lwoff’s discovery of the mechanism of lysogeny, microbiologist Félix d’Herelle and pathologist Peyton Rous, who themselves first discovered and argued for the viral identity of bacteriophages and certain types of cancer, respectively, faced opposition from contemporary researchers who would not accept their findings. By following the research trajectories of the two virus groups, Sankaran takes a novel approach to the history of the development of the field of medical virology, considering both the flux in scientific concepts over time and the broader scientific landscapes or styles that shaped those ideas and practices.

Available in PDF, EPUB and Kindle. Book excerpt: Is cancer a contagious disease? In the late nineteenth century this idea, and attending efforts to identify a cancer “germ,” inspired fear and ignited controversy. Yet speculation that cancer might be contagious also contained a kernel of hope that the strategies used against infectious diseases, especially vaccination, might be able to subdue this dread disease. Today, nearly one in six cancers are thought to have an infectious cause, but the path to that understanding was twisting and turbulent. ​ A Contagious Cause is the first book to trace the century-long hunt for a human cancer virus in America, an effort whose scale exceeded that of the Human Genome Project. The government’s campaign merged the worlds of molecular biology, public health, and military planning in the name of translating laboratory discoveries into useful medical therapies. However, its expansion into biomedical research sparked fierce conflict. Many biologists dismissed the suggestion that research should be planned and the idea of curing cancer by a vaccine or any other means as unrealistic, if not dangerous. Although the American hunt was ultimately fruitless, this effort nonetheless profoundly shaped our understanding of life at its most fundamental levels. A Contagious Cause links laboratory and legislature as has rarely been done before, creating a new chapter in the histories of science and American politics.

Book excerpt: In the final years of the twentieth century, emigres from mechanical and electrical engineering and computer science resolved that if the aim of biology was to understand life, then making life would yield better theories than experimentation. Sophia Roosth, a cultural anthropologist, takes us into the world of these self-named synthetic biologists who, she shows, advocate not experiment but manufacture, not reduction but construction, not analysis but synthesis. Roosth reveals how synthetic biologists make new living things in order to understand better how life works. What we see through her careful questioning is that the biological features, theories, and limits they fasten upon are determined circularly by their own experimental tactics. This is a story of broad interest, because the active, interested making of the synthetic biologists is endemic to the sciences of our time."

Available in PDF, EPUB and Kindle. Book excerpt: Databases have revolutionized nearly every aspect of our lives. Information of all sorts is being collected on a massive scale, from Google to Facebook and well beyond. But as the amount of information in databases explodes, we are forced to reassess our ideas about what knowledge is, how it is produced, to whom it belongs, and who can be credited for producing it. Every scientist working today draws on databases to produce scientific knowledge. Databases have become more common than microscopes, voltmeters, and test tubes, and the increasing amount of data has led to major changes in research practices and profound reflections on the proper professional roles of data producers, collectors, curators, and analysts. Collecting Experiments traces the development and use of data collections, especially in the experimental life sciences, from the early twentieth century to the present. It shows that the current revolution is best understood as the coming together of two older ways of knowing—collecting and experimenting, the museum and the laboratory. Ultimately, Bruno J. Strasser argues that by serving as knowledge repositories, as well as indispensable tools for producing new knowledge, these databases function as digital museums for the twenty-first century.

Book excerpt: It has been said that 'the discovery of the Na, K-ATPase by J. C. Skou in 1957 must rank as one of the most influential contributions to Bioenergetics and Cell Physiology.' The ion-transporting enzyme has since been acknowledged as a vital 'pump' in all cells. Skou's memoirs tell the story of a Nobel Prize-winning breakthrough in biochemistry. But during his voyage of discovery he also repeatedly finds occasion to speak out in defence of the basic principles of scientific research. 'We would, ' as Skou says in one of his speeches, 'do well to promote science by encouraging young people to engage with their profoundly human capacity for astonishment, and wonder.' The ion-transporting pump continues to surprise. Its involvement in genetic disease is the latest addition to our understanding of this fascinating mechanism, and there will likely be much more to learn in the future.

Available in PDF, EPUB and Kindle. Book excerpt: The surprising history of the scientific method—from an evolutionary account of thinking to a simple set of steps—and the rise of psychology in the nineteenth century. The idea of a single scientific method, shared across specialties and teachable to ten-year-olds, is just over a hundred years old. For centuries prior, science had meant a kind of knowledge, made from facts gathered through direct observation or deduced from first principles. But during the nineteenth century, science came to mean something else: a way of thinking. The Scientific Method tells the story of how this approach took hold in laboratories, the field, and eventually classrooms, where science was once taught as a natural process. Henry M. Cowles reveals the intertwined histories of evolution and experiment, from Charles Darwin’s theory of natural selection to John Dewey’s vision for science education. Darwin portrayed nature as akin to a man of science, experimenting through evolution, while his followers turned his theory onto the mind itself. Psychologists reimagined the scientific method as a problem-solving adaptation, a basic feature of cognition that had helped humans prosper. This was how Dewey and other educators taught science at the turn of the twentieth century—but their organic account was not to last. Soon, the scientific method was reimagined as a means of controlling nature, not a product of it. By shedding its roots in evolutionary theory, the scientific method came to seem far less natural, but far more powerful. This book reveals the origin of a fundamental modern concept. Once seen as a natural adaptation, the method soon became a symbol of science’s power over nature, a power that, until recently, has rarely been called into question.

Available in PDF, EPUB and Kindle. Book excerpt: By focusing on chromosomes, Heredity under the Microscope offers a new history of postwar human genetics. Today chromosomes are understood as macromolecular assemblies and are analyzed with a variety of molecular techniques. Yet for much of the twentieth century, researchers studied chromosomes by looking through a microscope. Unlike any other technique, chromosome analysis offered a direct glimpse of the complete human genome, opening up seemingly endless possibilities for observation and intervention. Critics, however, countered that visual evidence was not enough and pointed to the need to understand the molecular mechanisms. Telling this history in full for the first time, Soraya de Chadarevian argues that the often bewildering variety of observations made under the microscope were central to the study of human genetics. Making space for microscope-based practices alongside molecular approaches, de Chadarevian analyzes the close connections between genetics and an array of scientific, medical, ethical, legal, and policy concerns in the atomic age. By exploring the visual evidence provided by chromosome research in the context of postwar biology and medicine, Heredity under the Microscope sheds new light on the cultural history of the human genome.

Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

Book excerpt: In the summer of 1998 two of baseball leading sluggers, Mark McGwire and Sammy Sosa, embarked on a race to break Babe Ruth’s single season home run record. The nation was transfixed as Sosa went on to hit 66 home runs, and McGwire 70. Three years later, San Francisco Giants All-Star Barry Bonds surpassed McGwire by 3 home runs in the midst of what was perhaps the greatest offensive display in baseball history. Over the next three seasons, as Bonds regularly launched mammoth shots into the San Francisco Bay, baseball players across the country were hitting home runs at unprecedented rates. For years there had been rumors that perhaps some of these players owed their success to steroids. But crowd pleasing homers were big business, and sportswriters, fans, and officials alike simply turned a blind eye. Then, in December of 2004, after more than a year of investigation, San Francisco Chronicle reporters Mark Fainaru-Wada and Lance Williams broke the story that in a federal investigation of a nutritional supplement company called BALCO, Yankees slugger Jason Giambi had admitted taking steroids. Barry Bonds was also implicated. Immediately the issue of steroids became front page news. The revelations led to Congressional hearings on baseball’s drug problems and continued to drive the effort to purge the U.S. Olympic movement of drug cheats. Now Fainaru-Wada and Williams expose for the first time the secrets of the BALCO investigation that has turned the sports world upside down. Game of Shadows: Barry Bonds, BALCO, and the Steroid Scandal That Rocked Professional by award-winning investigative journalists Mark Fainaru-Wada and Lance Williams, is a riveting narrative about the biggest doping scandal in the history of sports, and how baseball’s home run king, Barry Bonds of the San Francisco Giants, came to use steroids. Drawing on more than two years of reporting, including interviews with hundreds of people, and exclusive access to secret grand jury testimony, confidential documents, audio recordings, and more, the authors provide, for the first time, a definitive account of the shocking steroids scandal that made headlines across the country. The book traces the career of Victor Conte, founder of the BALCO laboratory, an egomaniacal former rock musician and self-proclaimed nutritionist, who set out to corrupt sports by providing athletes with “designer” steroids that would be undetectable on “state-of-the-art” doping tests. Conte gave the undetectable drugs to 28 of the world’s greatest athletes—Olympians, NFL players and baseball stars, Bonds chief among them. A separate narrative thread details the steroids use of Bonds, an immensely talented, moody player who turned to performance-enhancing drugs after Mark McGwire of the St. Louis Cardinals set a new home run record in 1998. Through his personal trainer, Bonds gained access to BALCO drugs. All of the great athletes who visited BALCO benefited tremendously—Bonds broke McGwire’s record—but many had their careers disrupted after federal investigators raided BALCO and indicted Conte. The authors trace the course of the probe, and the baffling decision of federal prosecutors to protect the elite athletes who were involved. Highlights of Game of Shadows include: Barry Bonds A look at how Bonds was driven to use performance-enhancing drugs in part by jealousy over Mark McGwire’s record-breaking 1998 season. It was shortly thereafter that Bonds—who had never used anything more performance enhancing than a protein shake from the health food store—first began using steroids. How Bonds’s weight trainer, steroid dealer Greg Anderson, arranged to meet Victor Conte before the 2001 baseball season with...

Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book excerpt: Entering an Unseen World is an in-depth story about how a singular laboratory contributed to creating a new science, modern cell biology. The story begins in 1910, in a laboratory devoted to studying cancer at The Rockefeller Institute for Medical Research, and culminates in 1974 when the Nobel Prize was awarded to three pioneering scientists. Chapters devoted to the early years offer a compelling narrative about this laboratory while focusing on five aspects of how this science unfolded through time: the hundreds of scientists involved, a nurturing environment, the experimental procedures developed, the instruments devised and mastered, and the discoveries made in a previously unseen world. First-person chapters by more than 20 scientists associated with this laboratory follow. They describe their roles exploring the intricate and fascinating world inside living cells. Their stories show what it takes to create a science while revealing in detail what we now take for granted: the cell is the basic structural and functional unit of all known living organisms. Nearly 150 classic illustrations and photographs document the evolution of their discoveries. Entering an Unseen World conveys the excitement of process and progress as this science came to life.
