New research suggests that lightening and volcanoes may have sparked early life on Earth. Researcher Jeffrey Bada at Scripps Institution of Oceanography at UC San Diego and colleagues reanalyzed Stanley Miller's classic origin of life experiment, offering a new analysis on how the essential building blocks of life may have arose from volcanic eruptions.

Bada, Scripps professor of marine chemistry and graduate student of Miller's in the Chemistry Department at the UC San Diego in 1960, preserved Miller's original chemical samples. Bada along with lead author Adam Johnson, Indiana University graduate student and colleagues, reanalyzed the samples to determine if new chemical compounds could be detecting using modern equipment. The paper, "The Miller Volcanic Spark Experiment," is published in the Oct. 17 issue of the journal
Science.
"We believed there was more to be learned from Miller's original experiment," said Bada, co-author in the paper. "We found that a modern day version of the volcanic apparatus produces a wider variety of compounds."
Comment: This is typical of the sort of pseudo-science that gets bandied around in relation to global warming. It escapes so many scientists - at least the ones that get airtime in the media and grants from government - that global warming is part of a natural cycle and has very little to do with man or the animals.
However, considering that the Great Chicago Fire is promoted as being started by the gaseous emissions from a cow, when it seems a comet was a much more likely candidate, it isn't really surprising that the increase in temperatures on Earth is also blamed on cows. But that does of course leave the question of how cows were able to heat up Mars and other planets in the solar system as popular science will not address the cosmic sources of this phenomena.
Given what passes for science on the matter of global warming it would not be surprising to read that a research grant has been awarded to a team of 'experts' who are investigating whether the warming of Mars is due to the gaseous emissions from the cow that jumped over the moon.
