A paleontologist searches for others things like teeth, claws, footprints and skin. They search for these clues in rocks that have preserved the dinosaurs for millions of years.

What happened to these students is a travesty. The school had no right to conduct these searches.

RISS' search feature just didn't have the granularity we needed. Searches like that were taking around two weeks, between searching for the e-mails, extracting the data, and then organizing it into an intelligible format for the auditor.

Web users are conducting more searches not because they can't find what they're looking for, but because search as a utility has become deeply ingrained into people's everyday lives.

The search terms are so small that with a sizeable percentage of searches any human can say there are a lot of ways I can interpret that.

Someday we must collect these rocks and bring them back to terrestrial laboratories to read their records for clues to the biological potential of Mars.
