Proteins and Proteomics
Researchers know it is the proteins made by a cell that determine what that cell does. This session explores the varying complements of proteins and their effects, structures, and interactions within the mechanism of cell function, and introduces the larger picture of proteomics and systems biology.
Cell Biology and Cancer
Cancers result when genes required for normal cell function are mutated and the resulting cells undergo other changes ultimately leading to uncontrolled division. This session reveals new information on normal cell function, proto-oncogenes and tumor suppressor genes and their role in the cell cycle, and current research in drug design for specific cancers.
An Introduction to Integration By Parts

Westward Movement and Economy
This video is accompanied by text. "By the mid-nineteenth century, the American economy that had been based on local commerce and small-scale farming was maturing into a dynamic, wide-reaching capitalist marketplace. As the industrial revolution in the northeast altered the economy and intensified the process of urbanization, an agricultural empire began to emerge in the west.
By 1860, more than one-half of the American population was located west of the Appalachian Mountains. Conditions
The Growth of Cities and Social Issues
This video is accompanied by text. "In the decades following the Civil War, many Americans migrated from farms and small country towns to the growing cities. Immigrants from several countries, including Germany, Ireland, Italy, and Poland traveled to America in search of better working and living conditions for themselves and their families. Between 1870 and 1900, the population of U.S. cities tripled. By 1890, New York became the second largest city in the world with 3.5 million residents, whil
The Progressive Era
This Progressive Era was a period from 1890-1920. The progressive movement tried to fix the problems of industrialization. Video is a series of pictures that show people working, the living conditions, presidents, amendments, different acts that were passed, and government reforms. (Amateur video that uses modern music as a background sound.)
Social Development in the late 1800s
This video is accompanied by text. "As inferior living and working conditions, along with corrupt city governments, were creating a bleak future for many U.S. cities, reformist leaders emerged to fight for the rights of the urban masses. Social crusaders attempted to eliminate the violent crime, prostitution, unsanitary living conditions, and unsafe work environments that were plaguing the quickly expanding cities.
During the late 1800s, activists established settlement houses to provide

Balance and flux
Ecosystems and populations of organisms within ecosystems function by the principle of balance and flux. Balance can be thought of as a state of equilibrium, or a state of equal changes between two sides. Flux can be thought of as a rate of flow or changes. Even small changes in an ecosystem's or population's balance and flux could lead to disaster.
