Finding life on Mars would excite researchers for a variety of reasons. Firstly, it would just be interesting to know that life did (or does) exist elsewhere in the universe. Humans have been wondering about this question almost as long as we have been in existence. Finding evidence that suggests that we may not be alone, that Earth is not the only planet capable of sustaining life, would be an amazing revelation. As for scientists, many want to know how and why life was created on Earth. See similar questions...

Kessel (1965) presents graphical evidence that shows that the term spread tends to be negative at cyclical peaks, using data that go back as far as 1858. He finds some evidence of the leading indicator properties of the spread in time periods from 1914 to 1933 and from 1954 to 1961. Bordo and Haubrich (2004) provide regression-based statistical evidence using U.S. data from 1875 to 1997 and Baltzer and Kling (2005) perform a similar exercise with German data from 1870 to 2003.

I want to be a paleontologist when I'm older and I was wondering what is the best university to go to for that career and how long would I have to go to school. See your school councellor, they probably have a lot of books (like the Barron's College guide) in which you can look up the particulars of each college that is within your price and academic range. Try to go to an undergraduate program (usually lasting 4 years) that will give you a decent knowledge of geology and biology. See similar questions...

Yes, the sheriff badge found its way onto a profile for a brief time. We had planned to use it as an award to those who helped us track down duplicate accounts. It was dropped as being too "secret police," but we still appreciate the tip-offs we get about dupes. I still can't believe people would actually go to the effort of "cheating" a system such as this. TIP: Never implement a method of exchanging tokens from one user to the next (or stamps or points, for that matter). See similar questions...
