Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins sheds new light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins. Using the latest scientific findings from psychology, psychiatry, biology, and education, the book separates fact from fiction. Each idea about twins is described, followed by both a short answer about the truth, and then a longer, more detailed explanation. Coverage includes embryology of twins, twin types, intellectual growth, personality traits, sexual orientation of twins, marital relationships, epigenetic analyses, and more. Five appendices cover selected topics in greater depth, such as the frequency of different twin types and the varieties of polar body twin pairs. This book will inform and entertain behavioral and life science researchers, health professionals, twins, parents of twins, and anyone interested in the fascinating topic of twins.

Twin Research: Biology, Health, Epigenetics, and Psychology is a comprehensive, applied resource in twinning and twin studies that is grounded in the most impactful findings from twin research in recent years. While targeted to undergraduate and graduate students, this compendium will prove a valuable resource for scholars already familiar with twin studies, as well as those coming to the field for the first time. Here, more than forty experts across an array of disciplines examine twinning and twin research methodologies from the perspectives of biology, medicine, genetic and epigenetic influences, and neuroscience. Chapters provide clear instruction in both basic and advanced research methods, family and parenting aspects of twinning, twin studies as applied across various disease areas and medical specialties, genetic and epigenetic determinants of differentiation, and academic, neurological and cognitive development.

The presentation of existing studies and methods instruction empowers students and researchers to apply twin-based research and advance new studies across a range of biomedical and behavioral fields, highlighting current research trends and future directions.

This volume is an annotated collection of original, informative, and moving photographs of the twins who survived the brutal medical experiments conducted at the Auschwitz-Birkenau death camp (1943-1945). The experiments were conducted by the infamous physician, Josef Mengele. These never-before-seen photographs were taken by the author (Segal) at the 40th anniversary of the camp’s liberation (January 27, 1985) and the public hearing on Mengele’s crimes at Yad Vashem (Hand and Name) in Jerusalem that followed. Other memorable moments, captured in photographs include traveling to Krakow, visiting Warsaw and hearing survivors’ testimonies. The photographs are organized into ten sections that unfold chronologically—each section is accompanied by a brief essay to provide compelling context and each photograph has an informative caption.
