Was Darwin Wrong? The work of the 19th-century English naturalist shocked society and revolutionized science. How well has it withstood the test of time? Evolution by natural selection, the central concept of the life's work of Charles Darwin, is a theory. It's a theory about the origin of adaptation, complexity, and diversity among Earth's living creatures. If you are skeptical by nature, unfamiliar with the terminology of science, and unaware of the overwhelming evidence, you might even be tempted to say that it's just a theory. In the same sense, relativity as described by Albert Einstein is just a theory. Each of these theories is an explanation that has been confirmed to such a degree, by observation and experiment, that knowledgeable experts accept it as fact. The rest of us generally agree. Evolutionary theory, though, is a bit different. This documentary is available for preview only.
DNA Structure - Contents page An Interactive Animated Nonlinear Tutorial by Eric MartzAdapted for using Jmol instead of Chime, by Angel Herráez Part of Biomodel website by Angel Herráez, Univ. de Alcalá (Spain) Disponible también en español. Também disponível em português. Auch verfügbar auf Deutsch. This version 4.3 works in any Java-compatible browser. If you prefer using Chime for molecular models, the page using it is still available, with equivalent content and functionality. This tutorial is designed to complement Biology or Biochemistry and Molecular Biology books, so it is not by itself a complete introduction to DNA structure. Before proceeding, check that your browser has Java installed and can use the Jmol software: This tutorial is designed to complement an introduction to DNA, by providing tools for a self-directed exploration.

HealthVault : Home Genetic themes in fiction films | The Human Genome Although the potential applications and implications of modern genetics and biotechnology have supplied much plot-material for English-language feature films during the past 25 years or so, there is no genre or sub-genre of 'genetic movies' as such. Rather, genetic themes and motifs have been appropriated, with more or less skill and subtlety, to add a contemporary gloss or twist to such well-established popular cinematic formats as the sci-fi thriller, the chase or pursuit movie and the family drama [see note 1 ]. More surprisingly, perhaps, genetic engineering and cloning have also provided material for a number of sci-fi comedies, from Woody Allen's Sleeper (1973) to Harold Ramis' Multiplicity (1996). Film review: Gattaca Film review: The Sixth Day Fact versus fiction Moreover, the representation of genetics in films in which genetic engineering or biotechnology play important roles is often seriously distorted by the generic tradition and conventions of science fiction films.

Home of CELLS alive! DNA From The Beginning Strange Days on Planet Earth Around the globe, experts are racing to solve a series of mysteries: how could a one-degree rise in average temperature have profound effects around the globe? How could crumbling houses in New Orleans be linked to voracious creatures from southern China? Hosted by actor-writer-director Edward Norton, this award-winning series uses state-of-the-art graphics and globe-spanning investigations to understand how our environment is changing and why? More and more plants and animals are turning up where they don't belong. In Uganda it took only a few years for water hyacinth, not native to the area, to rapidly spread around Lake Victoria, choking the banks.
