The Oil Spill's Unseen Culprits and Victims
The Gulf oil spill dwarfs comprehension, but we know this much: it's bad. Carl Safina scrapes out the facts in this blood-boiling cross-examination, arguing that the consequences will stretch far beyond the Gulf -- and many so-called solutions are making the situation worse. Carl Safina's writing explores the scientific, moral and social dimensions of our relationship with nature. This speech was given in June of 2010. Run time 19:56.
Video Documentary- In Papua, New Guinea, a group of initiates is about to enter the final stage of a long and arduous ritual. This is a male ritual that leads to manhood. Men's bodies are cut in the patterns of crocodile teeth. (Caution: Cutting and blood are shown.)
The Discovery of Penicillin
In this video segment adapted from A Science Odyssey, learn what led British researcher Alexander Fleming to the chance discovery of antibacterial properties of a mold extract he later named penicillin. After treating World War I battlefield casualties, Fleming began searching for compounds that would ward off infections in humans. Returning from vacation in the summer of 1928, he noticed that mold was partly covering one of the agar plates in which he had been growing bacteria, and that the mol
Red Blood Cells
In this video, the instructor demonstrates and discusses oxygen uptake by hemoglobin in red blood cells. The instructor uses computer software (and different colors for clarification) for demonstration.
A narrated, animated video explaining how the respiratory system works. Some key words include: alveoli, gas exchange, oxygen, carbon dioxide, and red blood cells.Run time 01:31
How the Body Works : The Filtering Mechanism
The filtering mechanism occurs at the Bowman's capsule of each nephron. As blood flows through the glomerular tuft, small molecules are forced through pores in the capillary walls into the nephron. Red blood cells and large protein molecules remain. The filtrate flows down the tubule and is joined by organic wastes and excess salts secreted from surrounding kidney tissues. Most of the glucose, amino acids, vitamins and essential salts are reabsorbed into the blood, leaving a concentrated solutio
How Bacteria Cause Disease
This video demonstrates how bacteria gain entrance to the body. It also explains that when a tissue becomes infected by bacteria, white blood cells migrate to the site of infection and begin to ingest the bacteria. If the white blood cells fail to destroy the bacteria, then the bacteria increase in number. Run time (2:13)
