Meth mouth: not ‘toxins’, just good ol’ tooth decay


As a long-time fan of media critic Jack Shafer, I remember well his diatribes against the myth that ‘meth mouth’ (the tooth decay that afflicts long-time methamphetamine abusers) is caused by the chemistry of methamphetamine or any contaminants from the preparation. The causes (dry mouth and lack of dental care) has been discussed in the …

What is that thing? The new GHS symbol for carcinogens


The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is the new international standard for shipping and labeling chemicals so that their hazards are communicated in a logical fashion. Since we’re now in a globalized commerce system, where (for example) Aldrich sells chemicals all over the world , GHS creates a single standard for how …

Gourmet ice? Yeah, it’s not really my thing either (I’m not much of a drinker, and when I do, it’s mostly microbrew.) But I found the story of entrepreneur Michel Dozois on the The Atlantic’s website to be pretty interesting and something that I find just tiny little bit terrifying as a chemist: Although he …

I don’t really wish to get into the political debate; suffice it to say that I …

How many ways can you say something without plagiarizing?


In a recent post by Derek Lowe on a Chinese journal’s finding that 31% of its submitted papers contained plagiarized material, an editor for a scientific journal noted in the comments that he randomly selected a Tetrahedron Letters paper from a developing country and Googled the first sentence. That sentence (“Multicomponent reactions (MCRs) are important …
