In four lectures, Dr. Michael Rosbash and Dr. Joseph S. Takahashi explain what circadian clocks are, how they work, and what relevance this knowledge might have for human health. They describe the techniques that led to their discoveries of the genes, proteins, and other components that make up these complex biological pacemakers. The scientists use animations to illustrate complex concepts and answer questions from their student audience.DVD includes detailed chapter search by scientific topic, direct access to animations, English subtitles, speakers’ biographies and interviews, and ideas for classroom activities.

DVD---How has the amazing diversity of plants and animals evolved? What can fossils, butterflies, and stickleback fish tell us about the deep common ancestry of all living forms? In four presentations, Dr. Sean B. Carroll and Dr. David M. Kingsley explore how key developmental genes, natural selection, and time fuel the evolutionary process. They also discuss how Charles Darwin’s ideas about evolution ignited a revolution in biology that continues to this day.

DVD---Leading evolution educator Ken Miller discusses the controversy surrounding the teaching of evolution, presents compelling evidence for evolution and reasons why "intelligent design" is not scientific. The presentation also features Dr. Miller's responses to questions from a live audience of high school students. DVD includes detailed chapter search by scientific topic; beautiful explanatory graphics;

DVD---Biomedical scientists can gain essential insights from patients that help move their research in new directions. In four lectures, Dr. Bert Vogelstein and Dr. Huda Y. Zoghbi discuss how their patients have led them to a deeper understanding of the genetic and molecular bases of cancer and neurological disorders. Dr. Vogelstein explains our current understanding of the biology of cancer and how scientists are using information about cancer genes to treat and prevent the disease. Dr. Zoghbi recounts the research journeys she took to find the genes associated with two devastating neurological disorders: spinocerebellar ataxia type 1 and Rett syndrome.

DVD---The sequencing of the human genome has set the stage for a vast revolution in the biomedical sciences. In four presentations featuring state-of-the-art animations and compelling graphics, Dr. Stuart L. Schreiber and Dr. Eric S. Lander open a window onto the fast-paced world of genomic science and chemical genetics. Dr. Lander explains how an understanding of small variations in DNA among individuals can help solve the mysteries of certain human diseases, and in particular, how DNA microarrary technology—gene chips—can be used to improve cancer diagnosis and guide treatment. Dr. Schreiber examines how technological advances coupled with data from the genome projects have energized chemistry’s contributions to biology and medicine.

DVD---The process of becoming a male or a female is complex and intricate. Researchers are gaining intriguing insights into how chromosomes, genes, and molecules are involved in sex determination. Dr. David C. Page explains the role of the human sex chromosomes, describing the evolution of the Y chromosome and the problems that arise in males when portions of the chromosome are deleted. Dr. Barbara J. Meyer looks at the genetic systems in the nematode Caenorhabditis elegans, which can develop either as male or a hermaphrodite. The scientists explore topics such as the role of sex, the evolution of the human sex chromosomes, human infertility, and the advantages of studying sex in a simple organism such as C. elegans. DVD includes detailed chapter search by scientific topic, direct access to animations and demonstrations, English subtitles, interviews with the speakers, and an interactive activity on gender testing.

DVD---RNA can be much more than a passive transmitter of genetic information. It can also act as an enzyme that directly participates in cellular biochemistry. In four lectures, Dr. Thomas R. Cech tells the story of the discovery of RNA catalysis—research that led to his receiving the 1989 Nobel Prize in Chemistry. He explores why RNA’s ability both to store genetic information and to catalyze biochemical reactions lends plausibility to the theory that RNA had a central role in the origin of life. Dr. Cech also reveals how the ability of RNA catalysts (ribozymes) to cut and splice RNA molecules has sparked efforts to develop them as new therapeutic agents against viruses, cancer, and genetic diseases.

DVD---Scientists are gaining a greater understanding of the genetic and molecular bases of cardiovascular diseases—knowledge that can lead to new tests and therapies. In four lectures, Dr. Christian E. Seidman and Dr. Richard P. Lifton discuss their groundbreaking research. Dr. Seidman explains how heart circulation works and discusses her research in identifying the mutant genes that cause hypertrophic cardiomyopathy, the most common cause of sudden cardiac death in young athletes. Dr. Lifton discusses his work on the genetics of hypertension and other diseases affected by the kidney’s ability to regulate salt. The lectures feature an animation on the anatomy of the human heart and questions from the student audience. DVD includes chapter search and English subtitles.

DVD---Can AIDS be cured? Why has it been so hard to develop a vaccine against HIV? How are new medicines revolutionizing AIDS treatment? In four presentations, Dr. Bruce D. Walker and Dr. Bisola O. Ojikutu explain why understanding HIV evolution is critical to fighting AIDS. DVD includes detailed chapter search by scientific topic; direct access to animations; English subtitles; interviews with the speakers; special features on adherence and resistence, the immune system, and retroviruses; discussions about living with HIV and students helping to fight the epidemic abroad, and a special feature on HIV/AIDS in South Africa.

DVD---Scientists are unraveling the mechanisms that dictate how the brain and body regulate weight. In four presentations, Dr. Ronald M. Evans and Dr. Jeffrey M. Friedman discuss what the latest advances in genetic and molecular research tell us about why some people are hefty while others are lean. Understanding the biological systems that control body weight and metabolism, as well as these systems’ environmental interactions, could lead scientists to treatments that curb obesity and treat its negative health consequences. DVD includes detailed chapter search by scientific topic, direct access to animations, English subtitles, interviews with the speakers, and special features on the molecular structures of fat, fat metabolism, and measuring obesity. Presented at HHMI’s Lectures on Science.

DVD---Sophisticated new techniques in molecular biology are allowing scientists to understand, combat, and prevent the spread of infectious diseases. In four lectures, Dr. Donald E. Ganem and Dr. B. Brett Finlay describe the latest advances in understanding how pathogens invade the body and how this knowledge is leading to the development of new therapies. They also explain how new infectious diseases are recognized and how epidemics arise. The lectures feature scientific animations, demonstrations, and student question-and-answer sessions. DVD includes detailed chapter search by scientific topic, direct access to animations and demonstrations, English subtitles, interview with speakers, and speakers’ biographies. Presented at HHMI Lectures on Science.

Book-100pgs--What do humans have in common with the lowly subjects of this report? Plenty. Scientists use these model organisms to study how genes function and apply what they learn to the study of human disease. A thorough description of new technologies used to analyze and compare the model organism genomes with the human genomes is included.
