This collection of 7 dazzling video clips focuses on various aspects of genetics ranging from history's DNA eureka moment, paternity testing, structural degradation of DNA, and tumor research using transgenic mice; to a human death gene and the role of stem cells in a freshwater polyp known as the hydra; to a case of gender/chromosome mismatch in which a girl is unable to naturally mature into a woman. Video clips include. * Genes: The Discovery of...

Genetic and neurological research has led to increasingly sophisticated medical capabilities-resulting in a growing number of moral and ethical quandaries. This cluster of NewsHour segments surveys recent milestones in biology-many of which have produced as much controversy as insight. Reporting on the newly-identified anti-aging gene SIR2 and the cross-species implantation of stem cells, the program also inquires into artificial limb technology,...

The next leader in the fight against cancer may be sitting in third-period Biology right now-but what will inspire his or her first steps into medicine? This video illustrates the awesome potential of a career in the life sciences, guiding students through fields that offer nearly unlimited possibilities for discovery. From the microscopic world of DNA, to the dazzlingly complex behavior of ants, to the mysteries of human physiology, the program explores...

From selective breeding in agriculture to animal cloning and the production of recombinant proteins, science continues to develop ways to modify the genetic code. This program spotlights the basic tools and techniques for manipulating DNA and how these are also used to investigate genetic functions. Viewers will learn about the coding and non-coding sections of DNA; the basics of PCR or the polymerase chain reaction; the use of viral vectors and plasmids...

This collection of 24 visually stunning video clips sheds light on pain, aging, and health threats. Special attention is given to the spine, a common source of discomfort; the effects of old age at both the macro and micro levels; and a variety of risks to physical well-being: malarial infection, food-related pathogens, alcohol overconsumption, naturally occurring bodily toxins, the common cold, and the indiscriminate elimination of epidermal bacteria...

Aging is a series of transitions, some gradual and some abrupt. How do people come to terms with these changes? This program examines the aging process from beginning to end, defining age from the viewpoints of biology, psychology, society, functionality, and the law. The impact of current behaviors and attitudes on one's future self is also discussed, as well as dying-itself a part of life-and the stages of grieving. In addition, the program addresses...

Although genetic modification of plants and animals has been going on since the dawn of agriculture, technological changes of unprecedented scope have taken place in the food industry within the past few decades. This program explores the impact of technology on food production and the development of new and emerging foods. Viewers are introduced to recently devised methods of genetic modification and selective breeding which have expanded both crop...

Why are girls entering puberty at progressively younger ages? Why are the rates of heart attack, cancer, and adult-onset diabetes rising? This program examines growing indications that food affects our genes-a concept vitally important to the science of epigenetics. Viewers encounter a wide range of experiments, case studies, and historical evidence, including Dutch birth records and testimonials from WWII that point to the epigenetic effects of starvation....
