This whistlestop guide teaches you everything you need to know about the fascinating science of genetics! Genetics is the study of heredity, and reveals how the characteristics of living organisms are determined by the genes passed down the generations. In humans, it can determine how we think,who we are, and how long we live. The human genome was mapped in 2003, and this enhanced ability to study our genes is transforming medicine, from CRISPR, the gene editing technology that allows us to alter the course of hereditary disease, to using genetics to identify the types of bacteria that populate our bodies. Stripping the subject to its bare necessities,30-Second Genetics charts the most extraordinary discoveries, from the fundamentals of cell biology to the almost unbelievable advances in DNA sequencing and stem cell technology. Each subject, concept or term is explored in a mere 30 seconds, 300 words, and one image, making this the perfect book to understand the field of genetics at lightening speed! Authors (and identical twin brothers) Jonathan and Matthew Weitzman are both expert professors in the field, and they write with clarity, exploring these complicated terms in easy to understand language. From advances in stem cell therapy to animal cloning, genetically modified crops and genetically tailored treatments, the Weitzman brothers demystify this essential science which is shaping our future, today!

This book examines the visual representations used in the popular communication of genetics. Drawing upon public science communication theories, information design theories, and social semiotics, the book offers both in-depth analyses and high-level synthesis of how genetics is visualized for the U.S. public from the early 20th century to the present. Individual chapters focus on six visual genres: photographs, micrographs, illustrations, genetic code images, quantitative graphs, and molecular structure images. Han Yu challenges readers to consider the significance of these images we often take for granted, including their historical contexts, scientific backstories, information richness, stylistic choices, economic motivations, and social implications. In doing so, the book reveals the complex cognitive, affective, and social-cultural factors that both shape and are shaped by these images. The book will be particularly useful to scholars of public science communication and visual communication, practitioners of science communication, and scientists from a range of related life science disciplines.

This book explores the double coding property of DNA, which is manifested in the digital and analog information types as two interdependent codes. This double coding principle can be applied to all living systems, from the level of the individual cell to entire social systems, seen as systems of communication. Further topics discussed include the ubiquitous problem of logical typing, which reflects our inherent incapacity to simultaneously perceive discontinuity and continuity, the problem of time, and the peculiarities of autopoietic living systems. It is shown that the scientific “truths” that appear to be coherent constructions connecting the scientifically verified observations by the rules of logic are in fact always relative and never absolute.

The history of the CCR5 gene as a lens through which to view such issues as intellectual property, Big Pharma, personalized medicine, and race and genomics.In The Genealogy of a Gene, Myles Jackson uses the story of the CCR5 gene to investigate the interrelationships among science, technology, and society. Mapping the varied “genealogy” of CCR5—intellectual property, natural selection, Big and Small Pharma, human diversity studies, personalized medicine, ancestry studies, and race and genomics—Jackson links a myriad of diverse topics. The history of CCR5 from the 1990s to the present offers a vivid illustration of how intellectual property law has changed the conduct and content of scientific knowledge, and the social, political, and ethical implications of such a transformation.The CCR5 gene began as a small sequence of DNA, became a patented product of a corporation, and then, when it was found to be an AIDS virus co-receptor with a key role in the immune system, it became part of the biomedical research world—and a potential moneymaker for the pharmaceutical industry. When it was further discovered that a mutation of the gene found in certain populations conferred near-immunity to the AIDS virus, questions about race and genetics arose. Jackson describes these developments in the context of larger issues, including the rise of “biocapitalism,” the patentability of products of nature, the difference between U.S. and European patenting approaches, and the relevance of race and ethnicity to medical research.

Obesity and diabetes develop as a complex result of genetic, metabolic and environmental factors and are characterized by increased lipogenesis and lipid accumulation in many tissues. Stearoyl-CoA desaturase (SCD) genes are a critical regulator of lipogenesis and catalyzes the synthesis of monounsaturated fatty acids (MUFA), mainly oleoyl- (18:1n9) and palmitoleoyl-CoA (16:1n7). These MUFAs are the major fatty acid substrates for the synthesis of triglycerides, cholesterol esters, wax esters and membrane phospholipids. There are 4 SCD isoforms (SCD1-4) in mice and two (hSCD1 and hSCD5) expressed in humans. At first glance, stearoyl-CoA desaturase enzyme would be considered a housekeeping enzyme because it synthesizes oleate a well-known fatty acid that is abundant in many dietary sources. However numerous studies have shown that SCD is a very highly regulated enzyme that features in so many physiological processes ranging from fat differentiation, carbohydrate and fat metabolism, inflammation and cancer. The editor's studies using stearoyl-CoA desaturase knockout (SCD1-/-) mice and studies of other investigators using pharmacological approaches to reduce SCD1 expression in mouse tissues have all established that the expression of SCD1 gene isoform represents a key step in partitioning of lipids between storage and oxidation. High SCD expression favors fat storage leading to obesity while reduced SCD expression favors fat burning and leanness. Although these studies clearly illustrated that SCD1 expression is involved in the development of obesity and insulin resistance, questions remain in the elucidation of the mechanisms involved and role of SCD1. This book includes chapters by leading researchers on SCD Genes in the brain, heart, muscle, liver metabolism, Colitis, and more. ​
