Uncle Wiki tells us: Phosphorescence is a specific type of
photoluminescence related to
fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with “
forbidden”
energy state transitions in
quantum mechanics. As these transitions occur less often in certain materials, absorbed radiation may be re-emitted at a lower intensity for up to several hours. As seen (by flash, so you don’t see their forbidden green fluorescent state) at Penders… aka
Ghost Fungus.

There’s not much you’re allowed to photograph in the Ngaanyatjarra Lands. But there’s no love lost for the feral camels that were culled last year following the invasions of local communities. Remember the uproar last Christmas when there was a camel plague Docker River? See here. This is where the remains of the cull were cremated. And there are still millions out there. Seriously.
And the solution? Some say it’s the dinner table! There’s been some talk of a central Australian camel abbatoir. But harvesting will not address the ongoing ecological issues – the ongoing pollution/loss of waterholes will have a massive impact on core populations of wildlife…

camouflage. noun 1. 1917, from Fr. camoufler, Parisian slang, “to disguise,” from It. camuffare “to disguise,” perhaps a contraction of capo muffare “to muffle the head.” Probably altered by Fr. camouflet “puff of smoke,” on the notion of “blow smoke in someone’s face.” I’m sure this isn’t what Gordon Bennett intended?
And then I wondered, there must be somewhere better than this window-sill for a moth to hang out, relax… which reminded me of
li-chen. noun 1. any complex organism of the group Lichenes, composed of a fungus in symbiotic union with an alga and having a greenish, gray, yellow, brown, or blackish thallus that grows in leaflike, crustlike, or branching forms on rocks, trees, or Ford Anglias.
And special thanks to Sharon Peoples who has lent me the fantastic Thames and Hudson/Imperial War Museum (2007) publication Camouflage by Tim Newark. This you must see.

A black-faced cuckoo-shrike and female satin bower bird cross paths in the tree outside my office a moment ago!

I nearly titled this post “dog p*rn”. And then I realized I’d be attracting the wrong kind of dog-lovers: if you’re brave, go here at the NYT.

Only last month a single bluefin sold at auction in Japan for more than US$175,000. Writes David Ritter on Unleashed… Read and be very afraid.
