New life for ancient DNA.

Qi

The vital life force in the body, supposedly able to be regulated by acupuncture. It corresponds roughly to the Greek pneuma, the Latin spiritus, and the ancient Indian prana. The concept of life-breath or vital energy was formulated as an indication of the awareness of man, originally directed externally toward nature or society but later turned inward to the self or life within. (From Comparison between Concepts of Life-Breath in East and West, 15th International Symposium on the Comparative History of Medicine - East and West, August 26-September 3, 1990, Shizuoka, Japan, pp. ix-x)

Ancient Lands

Geographical sites known to be extant in a remote period in the history of civilization, familiar as the names of ancient countries and empires.

Metaphor

The application of a concept to that which it is not literally the same but which suggests a resemblance and comparison. Medical metaphors were widespread in ancient literature; the description of a sick body was often used by ancient writers to define a critical condition of the State, in which one corrupt part can ruin the entire system. (From Med Secoli Arte Sci, 1990;2(3):abstract 331)

Quality Of Life

A generic concept reflecting concern with the modification and enhancement of life attributes, e.g., physical, political, moral and social environment; the overall condition of a human life.

Biogenesis

The origin of life. It includes studies of the potential basis for life in organic compounds but excludes studies of the development of altered forms of life through mutation and natural selection, which is EVOLUTION.
