Guano was once thought to be one of the most useful substances on the planet - so where did it all go? This is the true (and horrible) story of the Victorian addiction to bird poo.

I had the absolute joy of re-visiting the Port Logan Fish Larder in Galloway in stupendously good weather this weekend.

Quite apart from being a beloved fixture of family holidays (and the home of the adorable baby plaice that put my sister off sea food for life) the Larder is a unique piece of Scotland's maritime heritage.

Visitors have sought out this little treasure ever since it was completed in 1800.

One writer for the Dumfries Courier, in 1824, described meeting - 'One gigantic cod, which seems to answer to the name of Tom [...] blind from age or disease. The fisherman, however is very kind to him; and it is really affecting, as well as curious, to see the huge animal raise himself from the water, then resting his head on the flat stone, allow it to be gently petted'.

It's only £5 for an adult time as SO WORTH IT!

Giant Emerald Pill-Millipede: when these enormous millipedes are all rolled up, their bodies can be as big as a baseball, a tennis ball, or a small orange

This species (Zoosphaerium neptunus) is commonly known as a giant emerald pill-millipede. The females can measure up to 90mm long (roughly 3.5 inches), making this the largest species of pill-millipede in the world.

There is a significant degree of sexual dimorphism in this species, with the males measuring only about 45mm (1.8 inches) long -- roughly half the size of the females.

Giant emerald pill-millipedes are found only in Madagascar, which is home to several endemic species of giant pill-millipedes (order Sphaerotheriida). The Malagasy name for giant pill-millipedes is "Tainkintana," which means "shooting-star."

Pill-millipedes use conglobation as a defense mechanism, which means that they can curl their bodies up into a spherical shape so that their dorsal plates form a protective shield around the softer, more vulnerable parts of their bodies, just like an actual pill-bug or a "roly-poly."

When they roll themselves up completely, they look almost like gently polished chunks of malachite, emerald, or jade.

Giant emerald pill-millipedes will sometimes form large swarms that travel together as a group. This is the only species of giant pill-millipede that engages in any sort of swarming behavior, and the purpose of that behavior is still unclear. The swarms often contain thousands of individuals, with almost all of them moving in the same direction, even when there is no physical contact that might allow the millipedes to "herd" one another along.

Their swarming behavior also has some very peculiar features, as this article explains:

During swarming, Zoosphaerium neptunus individuals pay little attention to their surroundings; many specimens were observed walking straight into and drowning in small puddles. Some swarms even display ‘cliché lemming behaviour:' in Marojejy, a large part of a swarm walked into and drowned in a small river.

No single specimen was observed walking ‘against the current,' all specimens were moving in the same direction (southeast), even when not in contact with one another.

Of 273 randomly collected individuals, 105 were males, while 168 were females. The males were 8.3 - 14.1 mm wide (average width 10.4 mm). According to the inner horns of the posterior telopods, all males were sexually mature. The females were 9.95 - 15.4 mm wide (average width 11.4 mm). All females displayed non sclerotized vulvae and were sexually immature.

Some researchers argue that the swarming serves as a defense mechanism, providing a layer of protection (or at least some cryptic cover) against local predators, but the swarming behavior is still poorly understood.

Important Note: I just want to remind everyone that these animals belong in their own natural habitat -- they should not be trapped, bought/sold, traded, shipped, collected, or kept as pets. This particular species does not survive well in captivity, either, and the demand for these "exotic" invertebrates is putting the wild populations in jeopardy. The previous article discusses those issues, too:

Another possible threat for Z. neptunus swarms are collections for the pet trade. There exists a large demand in Japan, Europe and North America for 'green -eyed monsters’ as pets. Giant pill -millipedes from Madagascar unfortunately have a very short survival time in terraria. The species is specialized on low-energy food (dead leaves), and adapted to the cool climates (<20°C) of the highlands. Specimens in terraria often starve to death quickly.

So I know that they're adorable and really, really fascinating...but let's just let them be their chunky, adorable little selves out in the wild where they belong.

And God said, "Behold! I have created the fourth primordial force: the weak interaction!"

And the angels all clapped and nodded politely, and there was a long silence; and finally Verchiel, the Angel of Grace, spoke up and asked, "Er, what exactly does it do, O Fashioner?"

And God said, "What do you mean, 'what does it do?' It's the fourth fundamental force of the universe."

And Verchiel said, "You mentioned that. Um. But it's just that the other three sort of have a brand, you know? Gravity helps build large-scale structures, acts over vast cosmic distances, shapes time and space. The strong force is secret, hidden, binding together quarks and all that. Electromagnetism, very cool stuff, somewhere in between. We're all big fans of the whole magnetic monopole double bluff, very clever. But, er. What does this 'weak interaction' do?"

And God said, "It mediates radioactive decay. Sort of."

And Verchiel said, "Radioactive decay? All radioactive decay?"

And God said, "No. Just some kinds."

And Zephaniel, the Chief of the Ishim spoke, and he said, "A whole independent force just to mediate some kinds of radioactive decay?"

And God said, "Well. Not totally independent. Technically it's related to electromagnetism."

And Zephaniel said, "Wait, it's not even a real force?"

And God said, "It's totally a real force. It's just that it's one aspect of a combined electromagnetic and weak force. An electro-weak force, if you will."

And Metatron, the Celestial Scribe, scratched his head at this, but said nothing.

And Cambiel, the Angel of Transformation, said, "Maybe you can walk us through it from the top."

And God Sighed an immense Sigh, and said, "All right, fine.

"So the way it works is that all of space and time is permeated by a field that has imaginary mass."

And Cambiel said, "Imaginary mass, O Generous Provider?"

And God said, "Yes, imaginary mass. It's tachyonic, d'you see?"

And Sarathiel, the Angel of Discipline, said, "Wait a minute, I thought we agreed nothing was going to travel faster than light? All that 'c' business and the whole Lorentz transformation thing. What's happening with that?"

And God said, "Let me finish. The field is tachyonic. The particles in the field all move slower than light."

And Sarathiel had to think about this for a second.

And God said, "The point is, a field with imaginary mass has a non-zero vacuum expectation value."

And this really gave Sarathiel trouble, since he had never been very good at math.

And God, seeing this, went back to explain. "Most fields, like the electromagnetic field, have no effect when they are at their lowest energy state. It's like they're not there at all. If you give a field imaginary mass, then it vanishes only when it's at a very high energy state, and at a low energy state, it has a nonzero value everywhere."

And Sarathiel nodded, but he was confused, because he didn't understand why God would create such a thing.

But Verchiel thought he saw where God was going with this, and he was amazed.

"Truly, you are cunning beyond measure, O Only One Certainly Sound and Genuine in Truth! Only now do I understand your design! For in order to make the universe homogenous and isotropic, it is necessary that all large-scale fluctuations in temperature and mass must be evened out early in the history of the cosmos; and therefore, you have designed a field which will rapidly expand space after the Big Bang, many orders of magnitude in brief moments, and then swiftly and spontaneously decay as it gives up the energy it began with, giving rise to radiation and particles of all kinds as it does, which will condense into the material universe! It is a wonder to behold."

And God said, "What? No. I mean I did, but this isn't the inflaton field I'm talking about. This is something else."

And Verchiel said, "Wait, it's not?"

And God said, "No, I'm going to use a different field to drive cosmic inflation. The properties of this field are totally different."

And now Verchiel was also confused, and lapsed into silence.

And God said, "Like I was saying, this field is a scalar field with imaginary mass, and it does spontaneously decay to a ground state with a non-zero value. But it's not the inflaton field. Instead it combines with the W1, W2, W3, and B bosons."

And Metatron began to flip back through the pages of the Heavenly Record trying to figure out where he'd lost the thread.

And Zephaniel said, "The what bosons?"

And God said, "The W1, W2, W3, and B bosons. I'm sure I mentioned them. You know, the massless bosons?"

And Zephaniel said, "I'm pretty sure we only talked about the W+, W-, and Z0 bosons. All of which you said were going to have mass, O Owner of All Sovereignty."

And God said, "Yes, but this is how they get them, you see. Once this field acquires a nonzero value everywhere, the massless bosons interact with it and get mass. Well, some of them do. They turn into the W+, W-, and Z0 boson. And the photon."

And Zephaniel said, "…and the photon, O Accepter of Invocation?"

And God said, "Well, I did say I was going to unify the electromagnetic force and the weak interaction, didn't I? This is how. Above the critical temperature--right now I'm thinking 10^15 K, but I'm open to feedback on that one--electromagnetism and the weak force act as a single unifying force. Below that temperature, the field gets a nonzero value, you get three massive bosons to mediate the weak interaction, and the photon pops out seperately."

And Zephaniel said, "That seems… a bit overly complicated, doesn't it, O Reinstater Who Brings Back All?"

And God said, "No, it's exactly what we need. Look, that way the W and Z bosons have something to do, but the weak interaction still only travels short distances. Gravity is still the star of the show on cosmic scales, as it were. But now quarks and leptons can swap their flavor!"

And Zephaniel said, rather weakly, "Their… flavor, O Source of Good?"

And God said, "It's this new quantum number I'm trying out, to give the three generations of matter more unique identities."

And Cambiel said, "Three generations of matter? Now I'm really confused."

And God said, "I'm sure I mentioned this. You've got the lightest quarks and leptons, and then two heavier versions of each that can decay into the lighter versions."

And Cambiel said, "What do they do? New kinds of chemistry, is it?"

And God said, "Well, no. Mostly they just decay in a couple microseconds. Or even faster."

And Zephaniel began to rub his temples, and Cambiel sniffed.

And Cambiel said, "This all seems a bit ad hoc to me. Not really the stuff of an elegant and obviously ordered Creation. Why not have four generations of matter? Why not a trillion?"

And God began to grow irritable, and said, "Well, that's not really up to you, now is it? We're going to have three generations of matter, and the electroweak force, and that's that!"

And Zephaniel said, "As long as we are unifying fundamental forces, perhaps we could somehow also unify the electroweak interaction with the strong interaction, or even gravity."

And God hesitated saying, "Well, I haven't decided about that yet. I'm not sure I want gravity to be quantized, you know? Seems to take some of the geometric elegance out of general relativity."

And now it was Zephaniel's turn to sigh, and he bowed his head. "As you wish, O Possessor of Authority of Decisions and Judgement."
