Popular television shows, such as Finding Your Roots and Who Do You Think You Are?, have ignited a renewed passion for traditional genealogical research and thrown genetic ancestry testing into the spotlight. Once a tool only for historians and forensic scientists, DNA testing is now available directly to the consumer. Supporting the Next Generation Science Standards on heredity and inheritance of traits, this book uses simple language and detailed images and charts to explain how genetic ancestry testing is done, what it can, and cannot, reveal about a family tree, and the potential unintended consequences of being tested. Sidebars offer information about related topics, such as the Human Genome Project, mitochondrial Eve, and genetic genealogy careers.

Since cells are the smallest of all living organisms, scientists have had to develop various methods and tools to examine and research them. In the 17th century, the microscope was invented, allowing researchers a glimpse at the cell. Today, supercomputers put cells and experiments to the test. In microbiology laboratories and cancer research centers, well-trained, dedicated scientists work to explore the science of cells, making biotechnology a continuously growing field. In How Scientists Research Cells, Third Edition, learn how the first discovery of cells led to the first cloned mammal and additional scientific advancements.

The Evil Twins of American Television examines evil-twin depictions in over fifty years of television, comparing male twins to female twins and male-writer depictions to female-writer depictions. Kristi Rowan Humphreys evaluates The Patty Duke Show, Bewitched, Gilligan’s Island, I Dream of Jeannie, and The Brady Bunch, among other television programs that use the twinning trope to explore themes of feminism and identity. Employing traits identified by Betty Friedan in The Feminine Mystique as belonging to the “evil” side of her “schizophrenic split” theory, Humphreys analyzes the ways in which these alter ego characters embody the desire for a separate self and independence through loose inhibitions, career interests, political interests, intellectual prowess, and assertiveness. This book then compares female-written twin episodes to male-written twin episodes, finding that when “evil twin” episodes are written by women writers, the twins are presented less as oppositional binaries and more as compatible, often symbiotic binaries. Thus, the women writers of these shows offer a compelling response to Friedan’s text, one that acknowledges and underscores the many complexities of women—the image of which cannot in reality be so easily split into two oppositional binaries. Humphreys then connects 1960s depictions to more current evil-twin examples, including those in Friends, Knight Rider, and Sabrina the Teenage Witch.

Mercury is the only metal that is a liquid at room temperature. Mercurys chemical symbol is Hg. The Hg comes from the Greek word hydrargyrum, which means liquid silver. Because of its silvery appearance and the way it moves, the metal was also called quicksilver. In fact, the chemical is named for the Roman god, Mercury, who was known for his speed and mobility. Students learn about the sources of mercury and its effects on the environment (coal-burning power plants are responsible for nearly 40 percent of the human-caused mercury emissions in the United States). They learn about mercurys chemical properties and classification as a transition metal. Mercurys place on the periodic table and its subatomic particles are also discussed. Readers will study mercury ions and isotopes. The book also explains the elements applications in thermometers, thermostats, silent wall switches, fluorescent lights, and dental amalgams.
