Episodes Included in These Block Feeds
- 101. Session 1. Genomics
- Having determined the complete DNA nucleotide sequence of humans and several other organisms, today's researchers have shifted to identifying genes and determining their functions. This session reviews the techniques used in BLAST searches, microarray experiments, and other genomics tools. 29 minutes.
- 102. Session 2. Proteins and Proteomics
- Explores the varying complements of proteins and their effects, structures, and interactions within the mechanism of cell function, then introduces the larger picture of proteomics and systems biology. 29 minutes.
- 103. Session 3. Evolution and Phylogenetics
- Illustrates how molecular techniques are now combined with fossil evidence to explore evolutionary relationships in organisms from whales to anthrax. 29 minutes.
- 104. Session 4. Microbial Diversity
- Examines recent studies of microbes, including extremophiles, comparisons of bacteria and archaea, and the formation and life cycle of biofilms. 29 minutes.
- 105. Session 5. Emerging Infectious Diseases
- New diseases arise, and old diseases, such as malaria and influenza, are returning with renewed vigor. This session studies the complex causes and far-reaching impacts of emerging infectious diseases around the globe. 29 minutes.
- 106. Session 6. HIV and AIDS
- Explores recent developments in the study of HIV and AIDS, including what has been learned by studying individuals with natural resistance to HIV; the future global impact of the current infection levels; and the ethical issues surrounding current research and treatments. 29 minutes.
- 107. Session 7. Genetics of Development
- Organisms as different as flies, fish, and humans share a set of genes, known as a genetic toolkit, which guides development. Researchers present new perspectives on the remarkable similarity in these molecules and processes and discuss the ethical questions involved in this research. 29 minutes.
- 108. Session 8. 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 roles in the cell cycle, and current research in drug design for specific cancers. 29 minutes.
- 109. Session 9. Human Evolution
- Homo sapiens is now the only living representative of what was once a multi-branched bush of hominid species. Mitochondrial DNA and other fossil clues increasingly point to Africa as the point of origin of our species. How did humans replace their hominid cousins, including the Neanderthals, leaving the chimpanzee as our closest living relative? 29 minutes.
- 110. Session 10. Neurobiology
- Explains how neurons communicate and how their electrical activity results in the release of neurotransmitters that account for everything from survival to addiction to learning and memory. 29 minutes.
- 111. Session 11. Biology of Sex and Gender
- Examines recent findings which have challenged previous beliefs about the roles of anatomy, environment, and genetics in the determination of gender and explores the evolution of sexual determination. 29 minutes.
- 112. Session 12. Biodiversity
- With current extinction rates exceeding those of previous mass extinctions, many biodiversity studies focus on efforts to count Earth's species before they are lost. Other researchers are studying complex ecosystems to determine how environmental and biodiversity changes might affect their functions. 29 minutes.
- 113. Session 13. Genetically Modified Organisms
- While genetic modification of organisms has occurred for millennia, we now have the tools to insert specific genes from one organism into cells of unrelated species. This session illustrates the processes used; points out how increasingly common such genetically transformed organisms are in agriculture, industry, and medicine; and introduces the ethical considerations of this research. 29 minutes.
