Perhaps issues relating to neurochemistry are also integral to the zeitgeist of the early 21st century. We've got zombie movies all over big screens and small, of course. They begin with the premise that brains can be, well ... yummy. One wonders about the chemistry of that yumminess.
But, more seriously, it also turns out that neurochemistry allows for fossilization. This is not only a new discovery, it is one that has been acknowledged by a wide circle of scientists only after initial opposition.
Not much of a blog post, true. Just call this the "fleeting thought for the day."
