Optogenetics has been around for a decade, and the New York Times is ON IT.

In all seriousness, this piece offers a nice overview of some of the more exciting methodological developments in neuroscience from the past few years, including optogenetics and Clarity, techniques for activating neurons with light and turning brains transparent, respectively.

One thing they miss: CLARITY is an acronym. (It stands for Clear, Lipid-exchanged, Anatomically Rigid, Imaging/immunostaining compatible, Tissue hYdrogel.) Granted, it's a pretty ridiculous acronym.
