"Each of us began life as a single cell. From this humble origin, we embarked on a risky journey fraught with opportunities for disaster. Yet, amazingly, we reached our destination intact, emerging as dazzlingly complex, exquisitely engineered assemblages of trillions of cells. This metamorphosis constitutes one of nature's most spectacular yet commonplace magic tricks--and one of its most coveted secrets. In From One Cell, physician and researcher...

During her eight weeks of life, Leaney Lavea-born prematurely and with medically insurmountable abnormalities-was dependent on machines to live. But were these machines prolonging her life, or were they merely delaying her death? This deeply moving program explores the ethical dilemma surrounding a case that began in a hospital and ended up in court. Interviews with Baby L's parents, the attending physician, the Laveas' legal counsel, and others trace...
7) A New life

Description
This program looks at the events that lead from the fertilized cell to a human baby. Using film of living fetuses in the womb, it explains how the familiar human shape is "sculpted" out of the basic cell mass, what controls the timing of the various stages of fetal development, and what life is like for a fetus.

This program traces the development of a human being from conception to full-term fetus, with a focus on the functions of the male and female reproductive systems. The three stages of development in the womb-pre-embryonic, embryonic, and fetal, generated by the mechanisms of division, differentiation, morphogenesis, patterning, and growth-are illustrated, after which there is a close examination of male and female puberty-the maturation of the reproductive...

This, the first of four programs on reproduction and birth, looks at how the male and female bodies are prepared for their task of increasing the human race. The program shows the characteristics of sperm and ova and how each contains a partial blueprint for the future offspring. The mechanism of cell division is shown through exceptional microphotography, and the mechanisms of heredity are carefully described.

Science is identifying new biological processes that determine a person's sex. How will these findings affect the transgender and transsexual community? This program explores the latest research into gender development and the medical, cultural, and legal issues at the heart of the "brain sex" school of thought. Showing how human genome research has shifted scientific focus away from chromosomes, the video examines the role of brain receptors and...

Some of the most fascinating research in genetics today involves mutagens-physical, chemical, and biological agents capable of altering the structure of DNA. This program looks at the characteristics and behavior of mutagens and shows how they are prevalent in the world around us-for example, in the form of UV radiation, cosmic rays, and some radioactive isotopes, as well as synthetic chemicals and natural mutagens that may arise during the metabolism...

For most couples, getting pregnant is an easy matter, but not so for the 15 percent with infertility problems. This highly technical program designed for advanced anatomy courses and health-care practitioners focuses on the processes that lead to normal impregnation, and the physical hindrances that can prevent it. Superb microscopy and computer animation illustrate the processes, and show how reproductive medicine helps infertile couples over biological...

In this TEDTalk, Alexander Tsiaras shares his spectacular visualization that realistically depicts the development of a fetus from conception to birth - marveling as much at the technology as at the miracle of life itself. Tsiaras, chief of scientific visualization in Yale's Department of Medicine, wrote the algorithms for the micromagnetic resonance imaging machine that makes the computer-generated look at life inside the womb possible.

Although the impact of genetic research on human life is an ever-changing and often theoretical prospect, our current knowledge of the human genome already has direct, real-world applications. This program looks at several ways in which genetic breakthroughs have improved health care technology and enriched the study of human physiology. Case studies focus on DNA screening and its benefits-for both parents and children-in identifying hereditary problems,...
