I've received a question from a student in my "Nature of Life" course
about the association between light and sneezing which I thought merited
a search for information.  Does anyone know why it is that light induces

Another question is whether there are any side effects from breathing
Argon gas.  This is a case of industrial exposure, where the tank warns
that inhalation should be followed by removal to fresh air, and if not
breathing, give artificial respiration.  Sounds a bit threatening, but I
also know some manufacturers are a bit overzealous in their warnings. 
Anyone have any comments?
