Follows a family's unplanned Cesarean birth from early labor through recovery. An obstetrician explains the Cesarean procedure and discusses ways to minimize risk. Shows the surgical procedure using 3-D animation. Presents information on breast-feeding and recovery, and how to make a Cesarean birth a fulfilling experience. NOTE: Concludes with graphic footage of an actual Cesarean surgery.
Depicts the different stages in the birth and death of stars, including the sun. There are 100 billion stars in the Milky Way galaxy alone, and there are 100 billion galaxies. Provides an overview of radiated energy, which is in all wavelengths; nuclear fusion; and fierce magnetic fields, which create all solar events. Explains that the length of a star's life and how it dies are determined by gravity and how gravity is proportional to size.
Gravity rules the life cycle of stars. During the Red Giant dying stage in the life of an average size star, its outer layers are blown off in vast clouds of dust and gas called "nebulae" that contain hydrogen, oxygen, and nitrogen. Gravity crushes the remaining atoms into a remnant core called a white dwarf. The gravity of giant stars-10 to 20 times larger than average-will, at the end of their life in a supernova explosion, crush together even mutually repulsive protons and electrons, leaving a remnant rotating core of neutrons (i.e., a pulsar). Also explains how stars 20 to 100 times average size collapse into a core so dense that its gravity doesn't even allow light to escape (i.e., a black hole).
As shown on the History Channel. Four and a half billion years ago, the Earth formed from dust in space to become a molten ball of rock orbiting the Sun. Travels back in time to investigate how the fledgling planet survived a cataclysmic cosmic collision with another world, how molten rock solidified to land, how our oceans filled with water, and how life arrived on Earth. Geologists study the oldest rocks on Earth and meteorites from outer space to solve the geological mystery of all--the birth of the Earth.
While Dr. Oakley's family prepares for a birthday surprise, she tends to a sick yak and a pack of sled dogs. She also oversees the care of two orphaned eaglets. Part of the "Wilderness Vet" series.
Dr. Chris pays a visit to birthday girl Zambi, a big, boisterous lion cub who’s turning one. Dr. Lisa must attend to a cat that has swallowed a ribbon from a birthday present. She urgently needs to locate the ribbon and get it out, or her patient will have to undergo surgery. Finally, Dr. Chris must help get a cranky koala down from a tree. Part of the "Dr. Chris Pet Vet" series.
Explore the basic elements of pregnancy, labor, and childbirth in four chapters. Observe Deborah's experience from the beginning to the end of the childbirth process. Learn techniques to alleviate the pain of labor. Includes graphic depictions of childbirth.
For life to survive, it must adapt and readapt to an ever-changing Earth. The discovery of the Antarctic icefish has provided an example of adaptation in an environment both hostile and abundant, where the birth of new genes and the death of old ones have played crucial roles. Researchers Bill Detrich, Christina Cheng, and Art DeVries have pinpointed the genetic changes that enable icefish to thrive without hemoglobin and red blood cells and to avoid freezing in the icy ocean.
More than four billion years ago, the most important event in Earth's history took place: the ocean was born. It completely transformed the planet, creating a watery oasis that gave rise to the air that organisms consume, the climate, and a stunning array of life. The ocean is what transformed Earth into the livable, blue planet it is today. This episode tells the story of the ocean's turbulent beginnings and its successive incarnations. Part of the "One Ocean" series.
Covers the tumultuous events of birth, using fetoscopy and specially constructed models to show what happens from the fetus's viewpoint. Also shows the physiological events immediately following the birth: the almost instantaneous transformation of the heart from one pump to two, the baby's first sucking movements, and the establishment of the mother-child relationship. NOTE: Contains some nudity and shows a short sequence of an actual birth.
Demonstrates a variety of natural childbirth labor techniques. Covers having labor support from people you trust and creating a comfortable environment for birth. Includes techniques for early labor, active labor/transition, back labor, long labor, and positions for pushing and birth. Concludes with comments by women who have used these techniques. NOTE: Shows actual birth footage.
With recent advances in genetic and reproductive technology, couples can now rely on science to avoid giving birth to children with various genetic conditions. Explores the medical and ethical dilemmas that two couples face as they plan the birth of a child who may inherit their own genetic condition (dwarfism in one case, cystic fibrosis in the other). Bioethicists question the use of technology to ensure parents give birth only to a healthy child. NOTE: Includes footage of a baby being born via Caesarian section.
Explains how epidural anesthesia works and shows step-by-step how it is administered. Covers the possible side effects, benefits, and risks, including ways to reduce the chances of complications. Shows two couples as they make decisions about pain relief during labor and birth. NOTE: Shows an actual epidural procedure and vaginal birth.
Breakfast cereal was the birth of the health food movement. Before that, breakfast was usually a fatty and vein-clogging combination of bacon, fried eggs, flapjacks, and a mound of butter. The advent of corn flakes, oatmeal, and other quick-to-prepare breakfast foods changed the way people start their day. Part of the "Science to Go With Dr. Joe Schwarcz" series.
Three-year-old Lizzie tells the story of her mom's pregnancy and how she becomes a big sister. This award-winning childbirth video for children explains how a fetus develops, what pregnancy is like for mom, and what happens during birth. Discusses what's fun and what's hard about having a new baby in the house. NOTE: Shows a short sequence of the actual birth.
Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.
Explores the nature, habits, and habitats of manatees, one of earth's most gentle creatures. Explains how they are endangered and how they are nursed back to health after accidents with boats.
Our middle-aged sun has fascinated people throughout history, but only since the rocket age have scientists been able to document its life and the forces that sustain it. Explores sunspots, solar cycles, the birth of a solar storm, and the use of specialized spacecraft outside earth's ionosphere.
When is it necessary to induce or augment a labor? Answers questions expectant parents may have about these procedures. Explores the advantages, risks, common medical methods, and natural alternatives available for both induction and augmentation. An obstetrician lists questions expectant parents should ask their caregivers. NOTE: Concludes with footage of a vaginal birth.
