In the second part of talk, I explore other clues that suggest that genomes are not at equilibrium. Some genes appear to be changing more slowly and these older "fossil" genes in modern day genomes may give us insight into the distant past. I also hope to convince you that many of the great mysteries in contemporary biology do not require big research labs but can be solved through "home genomics"- piecing together information through a computer, the internet, and an inquisitive mind.

By looking at the light from distant galaxies and having well-established calibration methods, astrophysics can make hypotheses about the history of our universe. Do we have similar "rulers" in biology that could allow us to reconstruct the remote past and the evolution of species on this planet? The answer is likely "yes" and the clues are undoubtedly contained in the many whole genome sequences that are now available for inspection. However, it is critical to evaluate the assumptions that...

Scientists from NASA present cases for and against space missions to Mars and whether it is time for humans to step on the Red Planet.

Is man's fate tied to the Red Planet? Scientists debate the future of space exploration.

A discussion on the advantages of exploring Mars, the Marcian environment, the scientific development brought about by space missions and the significance the planetary research has has on humans and technological development led by Robert Zubrin, President of the Mars Society, Dr. Christopher McKay, a Planetary Scientist, Dr. Louis Friedman, Director of Planetary Society, and Dr. Edwards Weiler, a NASA Space Science Administrator. The president of the Mars Society makes a passionate case...
