Submission + - Small doses of 'sewer gas' could greatly boost food, biofuel production->

vinces99 writes: Low doses of hydrogen sulfide, which has been implicated in some of Earth's mass extinctions, could greatly enhance plant growth, bringing a sharp increase in global food supplies and plentiful stock for biofuel production. In the new research reported April 17 in the journal PLOS ONE, University of Washington biologist Frederick Dooley set out to examine the toxic effects of hydrogen sulfide on plants, but he mistakenly used only one-tenth the amount of the toxin he had intended. The results were so unbelievable that he repeated the experiment. Still unconvinced, he repeated it again – and again, and again. In fact, the results have been replicated so often that they are now “a near certainty,” he said.
