Biology is a broad field • Multidisciplinary • Chemical machines inside our cells • Ecosystems and Global Climate Change. Career Genetics Human Genome • DNA sequences • Deoxyribonucleic Acid, in native form is a double stranded helix Model of DNA Career Molecular Biology Stem Cell Research • President Bush appears at his ranch in Crawford, Texas, after announcing he supports funding for limited stem cell research, Thursday, Aug. 9, 2001. Bush decided on a compromise and will limit federal funding for embryonic stem cell research. The decision had been one of the toughest for Bush since he took office.

This was hinted at by old Viking images, but the new MGS images are pretty compelling. Origin of Life Oxygen Origin of Life Fossils NASA’s Terrestrial Planet Finder: The Search for (Habitable) Planets Biology What is Life? DETAILS, Details, details … Descriptions and Mechanisms What is Life? Ingestion, metabolism and excretion Departure from thermodynamic equilibrium Nucleic acids, proteins and other macromolecules Reproduction, mutation and reproduction of it's mutations (Carl Sagan (1934-1996) Scientific American 10/94, p94) Creating Life in a Computer Artificial Life Researchers... "define life not by it's substance but by its organization, which can include the patterns of information in a computer. They believe that life in all it's forms has a mechanism for processing energy and information that emerge from some fundamental order in the universe, a new natural law that shapes those forms out of chaos."
