Best new word I've seen all January appears in John Horgan's recent post on Scientific American's site. I won't give it away, but if you're too impatient to read the whole thing, just text-search the page for the first instance of cute. It comes right before that.
Though of course I agree with John that it is "not a counterargument," I do not think this word is just "cute." It's great!
Of course, who among us can really say what John Horgan means by "cute," in this or any other universe?
[Update] Not so neo: I see I am Not Even Wrong about this. I should try harder to suss this kind of thing out.
