Between the high cost of fuel, and the environmental impacts of fossil fuel use, fuels derived from biological sources are receiving a lot of attention these days. But how efficient are they, and
what are the hidden costs (both financial and ecological) of their production and use?

history of water on Mars, and a bit of background on the argument you'll hear running in the background in related press releases.

background, I'll talk about what Darwin did and didn't do. I'll also talk about a number of cases in which people in subsequent centuries have (and continue to) wrap various other theories in
Darwin's name -- in attempts to either win their theories some respect, or to smear Darwin and his work.

Today, the 12th of February, 2008, is the 199th anniversary of the birth of Charles Darwin. Since this has been dubbed "Darwin Day," and all sorts of events are planned for the upcoming year

became what it is today, and what Darwin's unique contributions to the theory really were. In part one, we'll talk about the development of evolutionary theory leading up to Darwin and his
contemporaries.

While sorting through pictures for some "Scientific tourist" blog posts, it occurred to me that two of them together told an interesting tale. Listen in on this episode, and find out how two craters
-- one in Arizona and one in Bavaria -- helped a man named Eugene Shoemaker reshape how geology is conducted, and invent the field of planetary geology as a scientific discipline.
