New Release - Immune Response


New Release - Immune Response



IMMUNE RESPONSE, THE

Other than swelling at a cut, and maybe some pus or a slight fever, we would be forgiven for not being aware of the existence of the human immune system. It is however a highly complex system, and when it is overwhelmed, things can get a lot more serious. In this informative and engaging program the three levels of immune defence are explored in isolation and as part of a disparate yet interconnected system. High quality animations are used to illustrate the nature of specific and nonspecific defence mechanisms deployed by the human immune system. The role of human intervention in the defence against disease is also explored.

EUTHANASIA

When faced with years of pain and poor quality of life, why shouldn't a rational person be able to end their own life? For some, euthanasia means that people may be pressured - however subtly - into taking their own lives before their time. For others, euthanasia is a dignified and profoundly moral choice. In this excellent program, we explore the religious, moral and philosophical arguments surrounding euthanasia, providing both 'for' and 'against' arguments for this controversial and important topic. Featuring some of the world's finest minds on the topic, this program is bound to provoke healthy, informed debate.

GENETIC ENGINEERING

Genetic engineering is one of the great scientific breakthroughs in recent history, but it's not without controversies. Should we push genetic research to its absolute limit, or does it need limitations? This program looks at the possible benefits of genetic engineering, such as the curing of hereditary diseases and the creation of better, more efficient crops. It also explores the potential issues that arise with this new technology - the questionable morality of cloning, and the controversy that surrounds stem-cell research for example. Students will hear both a secular and religious perspectives on the morality of intervening in nature at the most fundamental level.

IVF

It is estimated that three million people worldwide have been conceived via in vitro fertilization, or IVF. Having this still relatively recent technology has led us to question who 'deserves' it, and the extent to which an embryo should be engineered. Some parents-to-be use IVF to avoid potential hereditary diseases, yet should parents be allowed to choose things like sex, hair and eye colour? Should IVF be free, and if so, should it be free for everyone? This program looks at how different countries have navigated this new ethical territory, and investigates the often opposing stances that various religions have towards the practice. How have the boundaries for artificial pro-creation been set?

DESIGNER GENES: THE SCIENCE AND THE ETHICS

Since its discovery in 1953, mankind has been increasingly fascinated with DNA, the genetic blueprint. From the selective breeding of plants and animals in agriculture, through to the production of recombinant proteins for medical purposes and, more recently, the cloning of animals, science has investigated ways of manipulating the basic genetic code. This program outlines the basic tools/techniques for manipulation of DNA and how these are being used to ask fundamental questions about how genes work. From a more applied angle we take a tour of the myriad ways these advances are being utilised in medicine, agriculture and the environment. Together with its applications, we discuss the range of ethical questions arising from genetic engineering and the manipulation of DNA to produce so called 'designer genes'.

INTRODUCTION TO BIODIVERSITY, AN

Biodiversity, why is it so crucial to our survival and the planets? Biodiversity makes up our many interrelated ecosystems and is something we must strive to sustain. This Australian made, curriculum fit program explores what biodiversity is, with a focus on the long term effects in Australia. Key interviews from Victoria University lecturers, the Threatened Species Network Wildlife Fund and a Zoologist highlight the importance and necessity of biodiversity in Australia. This program also offers suggestions on what we can do to conserve biodiversity on a day-to-day basis and gives a real world demonstration of such conservation in action with the recovery and rebuilding of the natural habitats of the endangered helmeted honey-eater.

MUTATIONS: CHANGING THE CODE

A mutagen is an agent (physical, chemical or biological) capable of altering the structure of DNA within our cells. Mutagens generally act either directly on the DNA themselves or produce chemicals that in turn act on the DNA causing substitutions, deletions, insertions, or rearrangement of important genetic code. In this program we take a look inside the human body to discover how the DNA in our cells can be affected by chemicals, radiation, and other things we encounter in our everyday lives. We also discuss how mutagens can result in the development of cancers in the human body.

ROLE OF ENZYMES, THE

Enzymes are the critical ingredient in every organism that make life possible. They are catalysts and drive every chemical reaction that takes place in the human body, enabling our bodies to be built from proteins, carbohydrates, and fats. In this program we investigate the role of enzymes in detail, offering both theoretical and practical examples. We look at how enzymes function in living organisms, enzyme kinetics, enzyme substrate complex, enzyme activity, and finally the power of enzymes in the 21st century. We demonstrate enzyme activity, and the affects of substrate concentration, the pH, temperature and inhibitors.

TRANSPORTATION SYSTEMS IN ANIMALS

This program explores the need for multicellular animals to have specialised internal transport systems. Following veterinary experts, we get an exclusive insight into the day-to-day activities of domestic animal health. Seeing what they do to save the life of that beloved family pet and at its core we see how the transport systems can efficiently distribute materials to and from all parts of the body, providing nutrients to cells and removing waste products. They also provide the vital link with the exchange (respiratory and excretory) systems. The evolutionary aspect of internal transport mechanisms is discussed. Following this is a detailed look at circulatory systems, including the differences between the closed systems of vertebrates and the open systems of invertebrates.

TRANSPORTATION SYSTEMS IN PLANTS

The earth's natural environment is home to millions of species of animals and plants, all made up of cells. But how do plants provide their cells with nutrients? Just like animals, plants rely on complex transport systems. These are systems that can efficiently distribute materials from soil and leaves to the parts of the plant where they are needed. This program explores why many multicellular plants have specialised internal transport systems, while looking at what a transport system is, how plants get their nutrition, and the structure and function of root hairs. Separate transport systems of the xylem and phloem are also discussed.

HOMEOSTASIS

Touch a hot stove and the muscles in your fingers will jerk your skin away before you've even registered the pain. Go for a run on a hot day and feel the sweat seep out of your pores. Stand outside in the cold in winter and count the length of time before your body begins to shiver. All these reactions are the result of homeostasis - that is, the mechanism by which our bodies - and the life support systems of all organisms - works to maintain a stable internal environment, despite changes in external conditions. In this program we'll explore the concept of homeostasis. We'll ask what homeostasis is, why it is important, take a look at detecting changes from the stable state, counteracting changes from the stable state, and how homeostasis works.

NATURAL SELECTION: ITS PLACE IN MODERN SOCIETY

Natural selection is a process which affects every species on Earth, including humans. Many people believe that as members of modern, technological societies we are immune to natural processes because we can modify our environment to suit our needs. This program illustrates how natural selection continues to affect us all in fundamental ways that will determine our future survival as a species. Included in the program is a brief explanation of natural selection, examples of how natural selection is operating all around us, how natural selection has affected human evolution and how it is still affecting our daily lives. The program concludes with the reciprocal view of how modern human society is affecting natural selection processes in the environment, and the consequences for the future of life on Earth.

    GENES AND CLONING

    There is a lot of controversy around genetic modification of organisms and cloning. This program looks at the way man has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased, so has man's ability to alter genomes. Animations show how genetic engineers are now able to construct and insert genes for desirable characteristics into plants and how technology is used to increase numbers of animals with desirable traits and screen out those with disease or lower food yields.

    CONFRONTING EPIDEMICS: THREE CASE STUDIES - SARS, AIDS, INFL UENZA

    This program examines modern day epidemics, using three case studies from the late 20th and early 21st centuries - SARS, HIV-AIDS, and influenza.

    Firstly, SARS took the world by surprise in early 2003, and was particularly prevalent in Hong Kong and the south of China. The program looks at the response by authorities in the area, and outlines how the Australian government handled fears.

    Secondly, HIV-AIDS exists in epidemic proportions in southern Africa, and the program includes reports from ABC journalists from South Africa and Kenya.

    The third epidemic, influenza has been around for more than a century and has claimed more human lives than any other disease. Experts predict that another epidemic could hit at any minute and the program explores how Australia is preparing itself.

    MECHANISMS OF EVOLUTION

    Evolution is the gradual change that can be seen in a population's genetic composition, from one generation to the next. The three main mechanisms of evolution include genetic drift, mutation and natural selection. The first part concentrates on Genetic Drift with the use of a model to demonstrate its effect on small and large populations. An example will also be used to explain how Genetic Drfit can lead to the formation of a new biological species over a long period of time. Then models of Mutation and Natural Selection are demonstrated and the results carefully tabulated and analysed. Examples of particular populations, which have likely evolved through each mechanism, are also highlighted.

    IN FOCUS: CLASSIFYING LIVING THINGS - THE HOW AND WHY OF THE FIVE KINGDOM CLASSIFI CATION

    This program shows how all living organisms are classified into five basic categories or kingdoms - Plants, Animals, Fungi, Protoctista and Monera. Using easily understood graphics and footage, this program explains how and why the five kingdom system was developed from two original kingdoms - plants and animals. It also covers how recent developments in genetics have provided significant insight into the nature of living organisms, and how new relationships between living organisms are continually discovered - which may lead to changes in the way we classify living things in the future.

    ENERGY IN ECOSYSTEMS

    Any ecosystem needs energy to sustain it, and the organisms within it. This energy comes in massive quantities from the Sun, although only a tiny fraction of the solar energy hitting the Earth goes towards sustaining life. The flow of energy through an ecosystem is complex, and vital to sustaining all life within it. This program explores energy flow through ecosystems, and how organisms at various levels in the food chain obtain their energy, use it, lose it, and store it. Number, biomass and energy pyramids are introduced, with a focus on the decreasing amounts of energy available to organisms at higher trophic levels. The concepts of niche, niche overlap, competition and limitations on organisms, are also introduced.

    GENES AND INHERITANCE: PRIESTS, PEAS, PUNNETS AND PEDIGREES

    It was in the latter half of the 19th century that Gregor Mendel paved the way for the study of Genetics. This program starts with Mendel, and introduces a number of important concepts, principles and definitions that form the basis of the modern understanding of genetics and inheritance.

    It covers the use of Punnet Squares for predicting the outcome of monohybrid and dihybrid crosses, and looks at gene linkage, sex linkage, and crossing over. The use of a Pedigree Analysis is a particularly useful way to trace how certain traits are passed down generations, and this program introduces Pedigree Analyses using examples of autosomal and sex-linked inheritance.

    INFECTIOUS DISEASES: CAUSES AND CONTROLS

    Infectious disease is still a major influence on the quality of life experienced by most of humanity. We are all familiar with, to some extent, the effect they have on us. Just over fifty years ago, our hospitals were used for isolation of patients suffering from incurable infectious diseases. Fortunately, things have improved for us and we only occasionally experience such disease.

    This is not the case in other less developed countries, where infectious diseases are still common. Although the twentieth century seemed to be the golden age for the treatment of infectious human disease, scientists are warning that the battle is certainly not over.

    KEEPING IT ALL TOGETHER: CELL MEMBRANES

    This program looks at the structure of cell membranes and their function, including compartmentalisation, regulation of the movement of materials, access to information, intercellular interaction, and as a location for biochemical activities. Using a combination of narration, video footage and graphics, the program covers how cell membranes operate and various ways in which materials can cross them, including diffusion, active and passive transport, osmosis, endo- and exocytosis. It also looks at some of the effects of osmosis, including plasmolysis and turgor in plants. Finally the program studies why the surface area to volume ratio of living things is important, and how organisms overcome the tendency for this ratio to decrease, as they grow larger.

    ALL SYSTEMS GO! ENERGY SYSTEMS OF THE BODY

    "There's a common misconception that the three energy systems of the body function like a set of light bulbs, switching from one to the other as the duration of exercise gets longer. Current research shows, however, that the ATP-PC, Lactic and Aerobic systems are used together for almost all physical activity. This program clearly explains how. With the aid of clear, animated diagrams and comments from experts like Peter LeRossignol, this program explains: - Anaerobic and aerobic glycolysis - How myosin and actin use ATP to contract muscles. - Oxygen uptake and oxygen deficit. - The interplay of the three energy systems. - Chronic and acute training effects. This program also has regular breaks for note-taking and discussion to ensure students can grasp this complex topic."

    POPULATION MANAGEMENT: FOXES, KANGAROOS, AND BRINGING BACK THE THYLACINE

    Farmers have always needed to go out and poison, trap and shoot foxes to keep their numbers down, but now Australian scientists have come up with a more effective and humane solution, by developing a contraceptive vaccine to control pest populations, including foxes, rabbits and mice. Zoologist Michael Archer says harvesting is the only way to ensure that kangaroos survive. It's important to put an economic value on kangaroos and not treat them as pests to be culled. In this way the populations are monitored and managed and protected from demise. And attempting to clone the Tasmanian Tiger, scientists are trying to use DNA from a preserved specimen to bring the thylacine back from extinction.

    HAND-ME-DOWN GENES: AN INTRODUCTION TO GENETICS

    This two-program series, uses animated 3D graphics and clear explanations to introduce the biology of genetics.

    1. How Genes Work
    This program introduces inheritance, the process that determines many of our individual features, such as body shape, height and hair colour.

    Using hair colour as an inherited characteristic, the program: investigates the cell nucleus, focuses on DNA, chromosomes and genes, and explains, with lively graphics, how these mechanisms work to determine many of the characteristics, not only of humans, but of all living organisms.

    The program presents students with a sound foundation on which to build their understanding of the latest developments in genetics.

    2. Family Patterns - Why are members of the same family so different?

    As a first step in exploring this question, the program: uses animated graphics to explain mitosis and meiosis, unravels the mystery of chromosomes and the part they play in sex determination and identical and fraternal twins, explains dominant and recessive expression of genes using Huntington's disease and Achondroplasia as examples, discusses mutations - cystic fibrosis, Down syndrome, and Klinefelter's syndrome, and explores some of the contentious realms of modern applied genetics: genetic testing, genetic engineering and gene therapy.

This program examines the techniques used to present food in its best light and focuses on the relationships between colour, texture and taste. It is presented by chef Brendan Hill A.S.C.C.A., who demonstrates how to transform the presentation of a bland looking dinner by making minor changes to the main ingredients.

    This program investigates the basic characteristics of aquatic and terrestrial environments and the adaptations of the plants that live in those environments. Among the specific areas examined are:
  • supporting structures and movement, including turbidity,
  • gaseous exchange and light absorption,
  • control of water balance via gains and losses, and
  • pollination and fertilisation.

    BIOLOGY FIELDWORK ONE

    This program shows students how that complete the practical fieldwork needed to investigate a local ecosystem. We see three biology students documenting their chosen site by conducting fieldwork tasks such as: choosing an ecosystem, accurately measuring the site, drawing up labelled scale maps showing the site in plan and profile elevations, recording the site's main features, identifying the dominant species, and taking note of the abundance and distribution of major flora and fauna species.

    It concludes by briefly explaining how to use field data to identify the food chains and food webs between species, and apply biological keys to classify species.

    INSECTS AND SPIDERS

    An excellent introductory program into the lifecycle of insects and spiders and the way in which survival of the species is ensured. It has four main sections: the lifestyle, how insects obtain energy, how insects protect themselves and protection for the young. Insects have an amazing array of methods to ensure their survival from odours, poisons, stings, mimicry, camouflage and unique self made "buildings". Those with physical characteristics and behaviour that are suited to their environment will survive.
