"Strikingly, colonies with disoriented dances had greater foraging success. Over time, bees exposed to disoriented dances showed reduced interest in dancing nestmates. This may explain why disoriented colonies had a higher foraging rate than oriented colonies, as bees did not waste time waiting for information."

From the abstract: "... We show that honeybees, with a miniature brain, can learn to use blue and yellow as symbolic representations for addition or subtraction. In a free-flying environment, individual bees used this information to solve unfamiliar problems involving adding or subtracting one element from a group of elements. This display of numerosity requires bees to acquire long-term rules and use short-term working memory. ..."

“We do not want to know languages, we want to know language; what language is, how it can form a vehicle or an organ of thought; we want to know its origin, its nature, its laws”. Who wrote this, and when? (No Googling!)
The author turns out to be a fascinating person (and no I did not know who he was till Klea sent me the query) very much in the tradition of von Humboldt. Indeed, his remarks are apposite to this day. I have started reading some of his work (they are available online). They are well worth the time.

There is something quite interesting about academic publishing. The content it receives it does not in any way pay for. The curation of this content (selection, editing, improving) is largely also unpaid for by them. In fact, both are effectively paid for by public bodies like the NSF, NIH, Wellcome Fund, SSHRC etc. yet the public that funds it does not have free access to it. Not surprisingly, this system has generated enormous profit for the relevant academic publishers (here). The profit margins are enormous (36% for E) and it is not incidentally tied to the fact that most of the content is freely provided. I am sure that E provides a service. What I am also sure about is that this service is vastly overpriced. At any rate, the days of this kind of monopolistic parasitism might be numbered. One can only hope.
