A compositive of photographs illustration three aspects of the paper.  Top panel is a photograph of square plant growth chambers about 1 cubic meter in volume used to subject growing plants to elevated CO2 levels. The lower right panel is a photograph of Arabidopsis plants, eight of which were grown under ambient levels of CO2 and eight of which were grown under approximately 3´ ambient levels of CO2.  The plants grown under elevated CO2 are noticeably larger.

Here are four photos of squiggly rocks on Earth. Can you guess which of these, if any, are evidence of past life on Earth? If we received similar photos, from let's say Mars, would we know if it is life or not?

What many don't realize is that the annual average daily temperature for Lafayette, Louisiana (69F) falls right between that of Los Angeles (66F) and Bermuda (72F). Some might say we have the optimal Goldilocks temperature. I think the city should market that more.

Lafayette is at a crossroads. The University sits at the hub of it all.
Prologue: Skip back to the turn of the 20th century when Lafayette as we know it was in its infancy. Back then, “downtown” meant dusty roads, a few streetlights and a railroad station.
