Marine biologists studying a specific species of mantis shrimp (Fangschreckenkrebse) that inhabits coral reefs—an explosion of colour, shade and shadow, have found that these crustaceans have some of the most advanced eyes compound eyes in the animal kingdom. These shrimp have sixteen distinct photo-receptive cells, ommatidium whereas human eyes only have four to filter for red, green and blue and contrast, to differentiate, to tune for three times more colours and perceive polarised light and across different spectra.

menagerie
Beyond mermaids and unicorns—and even enjoying less widespread popularity than rarer chimeras like griffins, harpies or the Vegetable Lamb of Tartary (cotton, not so much a monster), there is a neglected bestiary, which the marvelous Atlas Obscura pays tribute to. My favourite creature enrolled here is the odd Lidรฉrc from Hungarian folklore—a sort of familiar, hatched as the first of a brood from a black hen, after being incubated in a human armpit—according to some traditions.
This newly-hatched imp, industrious and loyal, eventually becomes also a curse and a liability. Though always at their master's disposal, such congress becomes a dangerous thing, but can be gotten rid of through a variety of equally specific rituals, like giving one's Lidรฉrc an impossible task, like a logical feed-back loop that will eventually cause a fatal-error. It reminds me of the notion that vampires exhibit arithmomania and are compelled to count whatever is cast out in front of them, like grains of rice, or the Greek custom of setting out a colander during the Christmas season to trip up evil spirits, since they are obsessed with numbers and will try to count all the holes. They only make it as far as two, however, since three, the Holy Trinity, makes them disappear and start all over. It's interesting that monsters are framed with compulsions and I wonder what that means.

cold fusion
Kottke shares some interesting developments on the world-wide initiative to harness essential limitless energy with nuclear fusion by creating a wee constellation of tiny terrestrial (or at least mundane—that is, below the sphere of the Moon). The project has a commendable mission statement, as the International Thermonuclear Experimental Reactor abbreviated ITER, or rather iter from the Latin for the way, it aims to bend physics to satisfy man's needs, like with Prometheus—punished for giving humanity the gifts and curses of fore-thought and fire, in a sustainable manner. Whether it is possible to contain this sort of power is uncertain, but progress seems in jeopardy due to the bureaucratic nature of such a collaboration.
Such a complex engineering project has even spawned its own form of currency to facilitate funding of grants, and I am sure that there are secreted cautions among the members, especially those who supply the world's traditional fuels—who spread rumours that bringing the CERN collider on-line would ingest the Earth in a microscopic blackhole. Kottke's posts are always value-added, waxing philosophical and triangulating with curious but cogent parallels, and wonders if in this case, it is not an effort better handed off to industry. Many of today's businesses, flush with money and not only interested in preserving the status quo (though dominance and vertical monopolies are not much different) might want their own stellar prestige project.

parallax view or high-noon
Slowly but surely creeping towards the hours where sunrise and sunset do not precede the work day, I found this map pretty keen, which globally illustrates how far time-zones around the world diverge from the true solar mean.
