Autism and Mercury
A recent study funded by the Centers for Disease Control and Prevention (CDC) in Atlanta claims that thimerosal, a mercury-based preservative used for many years in vaccines, is “not associated with problems in speech, intelligence, memory, coordination, attention, or other measures of childhood development.” For those unaware of the thimerosal controversy, it has been claimed by many that it causes or is a factor in the development of autism.

However, there is a glaring problem with this study. While it seemed comprehensive with respect to thimerosal exposure, it apparently did so by combing health plan records, not by attempting to measure levels of mercury in the actual bodies of the children or their mothers during pregnancy.…

While this is good and all, it doesn’t seem to address the Fundamental Theorem of Email: the rate you receive new email is directly proportional to the speed with which you reply. Some corollaries:…
Three Kinds of Cooperation
Ecologists speak about two types of cooperation — mutualism and commensalism — which distinguish whether both or just one of a pair is benefiting. I’d like to look at a different dimension of cooperation that has to do with communication. There are at least three different types of cooperation along this dimension, though perhaps you can distinguish more (if so, please post a comment!)…
