Miracle fruit. The berry itself has a low sugar content[7] and a mildly sweet tang. It contains a glycoprotein molecule, with some trailing carbohydrate chains, called miraculin.[8][9] When the fleshy part of the fruit is eaten, this molecule binds to the tongue's taste buds, causing sour foods to taste sweet. At neutral pH, miraculin binds and blocks the receptors, but at low pH (resulting from ingestion of sour foods) miraculin binds protons and becomes able to activate the sweet receptors, resulting in the perception of sweet taste.[10] This effect lasts until the protein is washed away by saliva (up to about 60 minutes).[11] The names miracle fruit and miracle berry are shared by Gymnema sylvestre and Thaumatococcus daniellii,[2] which are two other species of plant used to alter the perceived sweetness of foods.

And here are our old friends The Duke And Duchess Of Windsor, jumping nicely. Even with everything you know about Nixon, doesn't this graceful little hop make you slightly inclined to vote for him (although that's unlikely to be possible)? And somehow you feel like this picture tells you something about Robert Oppenheimer's character, and might reveal something of the mind behind the Manhatten Project.

The 30 Harshest Author-on-Author Insults In History

This post was originally published June 19, 2011.] Sigh. Authors just don’t insult each other like they used to.
