82) Homeostasis
Language
English
Description
In order to understand homeostasis in a natural setting, this program observes what happens to the body during a marathon race. By monitoring the various physiological responses of one of the runners, we show the many changes and adjustments being made in the body as the race progresses. The data obtained from the runner are used to explain in detail how the body regulates temperature, blood oxygen, blood glucose, water balance, heart rate, breathing...

This program presents the reality of cancer as experienced by patients. Commentary from Dr. Julia Rowland, director of the NCI's Office of Cancer Survivorship, focuses on a patient's quality of life as cancer treatment proceeds, as well as the impact of the disease on a patient's family. Five patients of varied ages and at different stages of the disease-including a 28-year-old woman with breast cancer and a 54-year-old man with Hodgkin's lymphoma...

This second video in the Principles of Flight series focuses on the forces of Thrust and Drag and how each can affect flight. Viewers then learn how pilots manuever through these forces using primary and secondary instruments which create movement around the three axes of flight. Key terms such as wing tip vortices, pitch, yaw, and roll are explained in detail, giving a clearer understanding of the mysteries of flight.

Cancer is currently the second leading cause of death in the United States, exceeded only by heart disease. In fact, 1 of every 4 fatalities in America is attributed to cancer, amounting to more than 1,500 deaths each day. After introducing the broad topic of cancer, this program narrows its focus to scrutinize breast, cervical, prostate, testicular, lung, and skin cancers. The symptoms of these cancers, as well as the steps that can be taken to minimize...

Newton's 3rd Law of Motion states that, "For every action there is an equal and opposite reaction. This video uses model rocketry to explore this concept, and introduces the basics of rocket propulsion and the forces that affect rockets in flight (thrust, gravity, and drag) A demonstration of the use of both solid fuel and compressed air rockets is shown, while colorful graphics illustrate key concepts and terms. It's a great way to generate interest...

I thought I was going crazy. I needed to talk to people who were experiencing what I was experiencing. When cancer strikes, spouses, siblings, or children can suddenly become caregivers for the ones they love, locked in a struggle with the disease as well as with their own feelings. Drawing on interviews with caregivers and the staff of Gilda's Club, the Manhattan-based support group, this program explores the emotional impact of cancer while offering...

A cancer diagnosis is always bad news, but the words "You have cancer" don't necessarily instill the fear and confusion they did three decades ago. This program demystifies cancer by explaining how varieties of the disease typically begin and develop. The program also highlights some of the innovative treatments that are helping more and more patients to become cancer survivors. In addition, scientists discuss the importance of early detection in...

The Pap smear was a diagnostic milestone in detecting precancerous cells. Researchers are developing similar tests, particularly ones based on genetic predisposition, as they learn to home in on other cancers. As this program illustrates, sophisticated screening is just one of the ways medicine has advanced the fight against a dreaded disease. The program also looks at the targeted destruction of tumors through drugs that either react to substances...

In order to be a competent pilot, one must develop a thorough understanding of how and why a plane flies, as well as the forces that affect the flight of an aircraft. This video gives viewers just that. It outlines the forces of Lift and Gravity on an aircraft and goes on to describe how different structures on the plane are used to control these forces. Experts on aeronautics and flight give exciting commentary on their area of expertise.

Just a generation ago, pediatric cancers were almost always fatal. But today, 80 percent of childhood cancers are cured-young patients are disease-free and go on to live a normal life span. This program explores how doctors and researchers achieved this milestone, considered one of the greatest success stories in modern medicine. Also, scientists detail how research into pediatric cancer helped oncologists to develop effective anticancer regimens...

While many today are barely keeping up with all the latest digital marvels, others are focused on finding ways to reinvent computing altogether - such as through recent efforts to engineer "quantum machines." The quantum mechanical nature of matter at the atomic scale may not only allow us to build information technologies with unprecedented levels of computational power, but may also lead us to discover and develop new ways of embracing the defects...
