Medical science, in some sense, continues to look for a "panacea" and an "elixir of life" of sorts. The current focus may be on the immune system along with the role of genes and interplay of heredity and environment - but the desires to "cure all", to "retard the aging process", and to increase the "quality of life" are strong motivating forces. The areas of scientific endeavor that research these first two "alchemical" goals cross several disciplines and sub-disciplines besides chemistry, i.e. molecular biology, biochemistry, biophysics, genetics, and immunology.
