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

Mitosis In Action
Observation of the cell division of C. elegans cells from a 1 cell embryonic stage over a 50 minute time course at 20 second intervals. Black and white with music. Grades 5-12. 54 sec.
The Stages of Mitosis
This is a computer-animated clip from Stages of Mitosis, a promotional piece, which begins with a fly-through of cells preparing to undergo mitosis (cell division).
