This rather tropical cover image illustrates work from Yan-Song Zheng and colleagues on amphiphilic calixarenes. They have shown that when amphiphilic calix[4]arene and carboxylic acids such as naproxen and ibuprofen interact the direction of the branched substituents can be reversed, changing the shape and size of the calixarene micelles from solid to hollow or linear. They liken this change in shape to an octopus engulfing fish!
