This one always shocks people the first time they hear it. Have you ever seen "carmine" on an ingredients label of some food in the red-purple color family? Yeah, you're eating bugs....

After this weekend's discussion of chirality in advertising, I figured I'd post an interesting, more rigorous example of chirality. Most chiral (left- or right-handed)molecules have "asymmetric" carbons, or ones with all different things attached....

Even in cosmetics. The scientific tour de force doesn't stop there; they also give you lessons on deuterium oxide, fullerenes, and liquid crystals. The deuterium oxide thing is puzzling - another cosmetics company purports to sell spritzers of D2O. It's...

The previous entry on raspberry ketones got me thinking about supplements in general. For the most part they don't cause people problems - which is pretty remarkable, considering a lot of them do have real druglike molecules in them. Most...

I have to admit, I am a sucker for common names. Why would you grab a bottle of mercury (II) chloride when you could get some "corrosive sublimate"? 3-methylindole? No thanks, give me skatole (named for its smell!). Methyl tert-butyl...

Everyone knows that many organic solvents won't mix with water (or, more generally, some polar solvents won't mix with some nonpolar solvents). What you might not know is that some highly fluorinated liquids aren't very polar at all, but they...

I love the story of valproate. About fifty years ago, an investigator was using a fatty carboxylic acid as a delivery vehicle for antiseizure medications. He looked at it alone in controls and, lo and behold, it was a drug...
