HIV Immunity
Excerpted from NOVA: "Surviving AIDS," this video segment showcases the work of Drs. David Ho and Stephen O'Brien. By examining the "outliers" -- in this case, people like Steve Crohn, whose cells repeatedly resisted HIV infection -- Ho and his colleagues found a genetic mutation that prevents the HIV virus from entering the cell. This video segment includes animation of HIV entering a white blood cell through the CD-4 and CCR-5 receptors on the cell's surface. Some individuals have no CCR-5 gen

Military and Economic Mobilization
In response to growing threats from the Axis Powers during the late 1930s, the United States Congress passed a series of Neutrality Acts and embarked on a more aggressive military preparedness program. In 1938, Congress announced that it sought "a Navy second to none," and doubled the tonnage of combat vessels two years later. The nine battleships and eleven Essex class aircraft carriers that were part of that build-up, however, were not commissioned until 1943. By the summer of 1941, the milita

The Urinary System
The urinary system is concerned with the formation and elimination of urine. In an adult, more than 2,500 pints of blood passes through the kidneys each day. Blood enters via the renal arteries and is filtered to remove most of the waste products of metabolism. Seven pints of filtrate are produced every hour. Purified blood returns to the body circulation via the renal veins. The filtering process is carried out by more than two million tiny kidney units, or nephrons, which produce a highly conc

Anatomy of a Kidney
There is a very brief video with still images of the kidney. This is a quote from the video:
"This cross section of a kidney, almost three times life-size, shows its blood supply and one of the filter tubules, a nephron, highly magnified. The nephron is a highly specialized coiled tubule measuring up to one inch in length. There are more than one million nephrons in each kidney. They function as the kidney's filter units. The kidneys filter unwanted materials from the blood and regulate th
