Genetics & DNA – The Genetic Theories of Aging
No organism lives forever. The length of time animals and humans live is influenced by their genes. Scientists have made astonishing discoveries concerning the role of genetics in determining life span and this holds promise of extending the lives of animals and humans. This program explains Genetics, DNA and genetic…
Cracking Your Genetic Code
Part of the Series: NOVA
What will it mean when most of us can afford to have the information in our DNA--all three billion chemical letters of it--read, stored, and available for analysis? Cracking Your Genetic Code reveals that we stand on the verge of such a revolution.
Genetic Engineering
Episode 31 of Redefining Reality
Explore the history of genetic engineering, which has roots in the imaginary hybrid creatures of ancient myth. Learn how real hybrids can be made by splicing genes for desired traits into the genome of an organism. Then discover how this brave new technology is being used.
Superlife: Genetic Manipulation
Designing Life. Man has been doing it for over 10,000 years. You may not be aware of it, but we are surrounded by "Superlife," life-forms manipulated by Man. Superlife looks at the stories of how these super organisms came to permeate our planet, and how the latest science is pushing…
Ted's Evolution
Charles Darwin started a revolution when he published his evolutionary theory in the late 1800s, challenging the belief that God created the world in seven days. Since then, Darwinian theory has become the accepted scientific doctrine but now an Australian scientist, Ted Steele, is stirring things up again. For years,…
Remarkable Plants: The Volvocales and Chlorococcales
The Volvocales and Chlorococcales share a common ancestry from a cell type exemplified by Chlamydomonas. Using live cells, this video shows how simple evolutionary trends working on Chlamydomonad ancestors have generated diversity and complexity. In Volvocalean evolution, unicellular ancestors became multicellular (e.g., Volvox) by daughter cells adhering after division. Concurrently,…
Genes and Identity
Episode 15 of Redefining Reality
The mechanism that drives evolution was not discovered until long after Darwin's death. Follow the clues that led researchers first to the cell nucleus, then to chromosomes and genes, and finally to the DNA molecule as the agent of heredity. Close by weighing the role of genetics in determining human…
Cell Division: Mitosis and Cytokinesis
An inspiring and challenging 20 minute video for high school or university biology students. This video starts by emphasizing the central importance of cells in life, and that living cells can only arise from other living cells by cell division. After distinguishing mitosis (nuclear division) from cytokinesis (cell division), several…
Exploring Coral Reefs: Reproduction and Survival
Enter the fantastic undersea world of corals to learn about the variety of reproductive strategies these tiny animals use to ensure their survival. Despite their limited distribution, coral reefs are vital to the health of the world's oceans and to people living near by. Join host Dr. Kiki Sanford as…
The Origin of Life
Episode 27 of Redefining Reality
Apply the reality-analyzing tools you've learned in the course to the problem of life. Consider the close connection between life and sunlight. Then look at the startling exception to this rule: the fauna that flourish around volcanic vents in the dark ocean depths. What does this tell us about life's…
Life’s Origins and DNA Computing
DNA, RNA, and the protein molecules they assemble are so interdependent that it's hard to picture how life got started in the first place. Survey a selection of intriguing theories, including the view that genetic information in living cells results from eons of natural computation.
The Aging Brain
We're all getting older every day, and scientific research has shown that starting in our twenties, some brain functions begin a linear decline. But is old age all doom and gloom? Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many…
