Defining Reality in the Life Sciences
Episode 14 of Redefining Reality
Study one of the most complete transformations of reality in history: the new picture of life that emerged from the evolutionary theory of Charles Darwin and Alfred Russel Wallace. Close by tracing their influence on William Golding's Lord of the Flies and on television reality shows.
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…
Cloning and Identity
Episode 30 of Redefining Reality
Modern technology has transformed procreation, birth, and parenting. Given the different donor and surrogate options, it's perfectly possible to have a child with five biologically contributing parents. What are the implications of this revolution, especially if human cloning becomes the next new option?
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.
Medically Enhanced Humans
Episode 32 of Redefining Reality
With the availability of cosmetic surgery, psychoactive chemicals, performance enhancing drugs, and other treatments, people are now free to redefine themselves in order to overcome their limitations. Probe a trend that is rapidly transforming what it means to be human.
The Secret Life of Ferns
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you in and around reproductive structures such as the sorus, sporangium, and antheridium and archegonium. You see dynamic events such…
The Secret Life of Leaves
Three dimensional animations, supported by aurthoritative narrations, explore the leaf surface and explain the functioning of the guard cells. The viewer is then taken inside the leaf to see the photosynthesis and conducting cells. Witness the dynamic events of guard cell movements, gas exchange and the transport of water and…
The Secret Life of Flowers
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you inside the flower to witness dynamic events such as pollination, gametophyte formation, fertilization, embryo formation and fruit formation are…
The Secret Life of Pines
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you inside the pollen cone and the seed cone to see reproductive structures such as sporangia, gametophytes and the archegonia.…
The Secret Life of Mosses
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Computer animations take you inside a clump of moss plants to illustrate external structure. You are then transported inside the tips of male and…
Diatoms: life in glass houses
Diatoms are an extraordinarily successful group of organisms and their many thousands of species have diversified and specialized so as to occupy every environmental niche. Part of their success derives from their unique protective cell walls, beautifully elaborate structures made of pure silica. However, living inside walls made of this…
