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.

AstrobiologyIn what may be their most significant discovery yet, Mars scientists say high-resolution pictures from MGS showing layers of sedimentary rock paint a portrait of an ancient Mars that long ago may have featured numerous lakes and shallow seas. This was hinted at by old Viking images, but the new MGS images are pretty compelling.

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." Byte 1/95 p45
