Odd Science

Researchers have discovered that you can blame your pudgy middle on bad chemicals.

According to researchers at McGill University in Montreal, Canada, a hormone secreted by the stomach can cause junkie-like behavior when you see food.

Pizza? Score! Chicken wings? Groovy! Chocolate cake? Drop that man!

The guilty culprit is not your lack of willpower, it’s the hormone ghrelin, which is made in your stomach. As you get hungry, ghrelin levels rise and when you’ve eaten, they wane. In the study, volunteers were given a shot of ghrelin and then shown pictures of scrumptious, irresistible food. Their brains lit up just like a junkie’s.

Alain Dagher, a neurologist at McGill, says this is probably an evolutionary mechanism that encouraged our distant ancestors to bulk up on tasty calories whenever they had a chance (which probably wasn’t very often.) Fast forward a few thousand years, to the Era of Addictive Chicken, and this spells an obesity epidemic.

According to the New Scientist: “Several pharmaceutical companies already have their sights set on ghrelin, as drugs that block the hormone may quell hunger and fight obesity.”

The problem? If you turn off the hormone, it may affect other parts of your brain. Like, the segment of your cerebellum that makes you happy. The part that prevents you from falling into a deep, sponge-cake-like depression. And then killing yourself.

So, a danger of suicide, but at least you wouldn’t be fat anymore.

In an attempt to help understand why there is so much absolute dreck on the web, I suggest that we establish SITI — the Search for Intelligence on Teh Internet, roughly based on the model of SETI (Search for Extraterrestrial Intelligence).

This is a project that is long overdue, and with any luck, we will have more luck finding intelligence than SETI.

The SETI movement was energized in the 1960s by Dr. Frank Drake, when he came up with an equation to estimate the number of extraterrestrial civilizations in our galaxy. Now, I’d like to (modestly) propose we use his equation to estimate the number of intelligent website we may be able to find on the net.

The Drake “equation” states that:

n= the total number of intelligent sites out there
R* is the rate of website formation on the Internet
fp is the fraction of those websites that have weblogs
ne is average number of weblogs which can potentially support coherent thought
fl is the fraction of the above which actually go on to demonstrate coherent thought
fi is the fraction of the above which actually go on to show a sense of humor as well
fc is the fraction of the above which are willing and able to communicate
L is the expected lifetime of such an intelligent website.

Yes, some may argue that looking for coherent thought on a weblog is misguided, but I believe it’s our best shot.

Prove me wrong.

No doubt some boffins will now take this flash of brilliance, and give us a script to help us figure it out in real time. However, let me give you my best guess:

6 million new websites each year
X .5 (% with weblogs)
X .5 (% capable of supporting coherent thought)
X .001 (% demonstrating coherent thought)
X .001 (% showing a sense of humor)
X .6 (willing and able to communicate)
X 3 (lifetime of website, in months)
= 2.7

Hmm. Well, if I assume The Skwib is one of the 2.7, then who are the other 1.7? My guess is that they’ll be found on humor-blogs.com or perhaps alltop. Hey, you can’t argue with this, this is science!

Obligatory link to Wikipedia article on the Drake Equation, if you’d like to know what those things really stand for. Thanks to Garette for the toothy alien.

It turns out that the long-distance “Twilight Bark” scene from 101 Dalmatians isn’t so fictional. (You know, the scene when the parents of the puppy-napped pooches, Pongo and Perdita, let all the other dogs in England know their young have been kidnapped by the chain-smoking, highly motivated and mildly deranged Cruella de Vil.)

Research from Eötvös Loránd University in Budapest (Hungary) shows that dogs can distinguish between other pooches’ barks. According to the New Scientist, the researchers: “measured the heart-rate fluctuations of pet dogs while playing them recordings of dogs barking at strangers and dogs barking to get attention.”

They discovered that dogs can distinguish between the different kinds of barking, and “it might be that they also understand,” says Péter Pongrácz, the lead researcher.

No word yet on if dogs are able to communicate via urine, but I suspect the answer is yes, and they call it pee-mail.

This dog was banned from the study, mostly because he was channeling Bud Abbot:

Having settled the issue of if the members of the Thunka Grunka tribe had free will or not, Thag settled back into life with his tribe.

For once, it was almost peaceful. He and his new mate, Twigla, were happy. Thag enjoyed the prestige and respect everyone gave him for leading the hunters so well. (Not to mention how they grokked his cave paintings and practically worshiped his beer.)

He and the other decent hunter, Fonzag, were in the process of training a new generation of young men. But they were having problems with Donjuag.

Donjuag was the son of Gnock, whom Thag had been unable to save from cave lions, so he felt even more responsibility. But Donjuag was a moody fellow. Unpredictable. He was also in love with Fonzag’s mate, the luscious Vunga.

“Heyyyyyy,” Fonzag said to Thag, as they walked out to their hunting grounds. “He’s being uncool with my lady.”

“Him not do anything,” Thag told Fonzag. “Him just infatuated.”

Donjuag ran by, his spear held high above his head, whooping with excitement.

“What him do?”

“Thag, that cat is full of energy,” Fonzag explained. “He’s not sleeping well either, at least that’s what his mom said.”

“Him crazy,” Thag said while Donjuag finished his sprint with a forward flip. The young hunter over-rotated and did a face plant. Thag laughed. “Donjuag funny.”

Donjuag, undeterred, got up, and did a back flip, whooping with delight.

Fonzag looked on, worried. Thag slapped his diminutive friend on the back (careful not to touch Fonzag’s ridiculous hair) and said, “Fonzag not worry. We wear Donjuag out on trail. Him too tired to pitch woo at Vunga.”

Donjuag started running again, landing a forward flip this time, and Fonzag grunted. “I don’t know, he’s got a lot of energy.”

Are you an insatiable snacking machine? Covered in blue fur? Now there is hope.

New research from the University of Birmingham in the UK indicates it may be possible to stop yourself from snacking if you use your brain.

They ran a test in which half the volunteers were asked to vividly remember and describe their last meal — lunch in this case — and the other half were asked to remember their last haircut. Then delicious, delicious cookies were served. Those who were asked to remember their last meal ate fewer cookies (or “biscuits” in UK parlance).

The researchers believe the vivid, specific memory stimulates the hippocampus, which they say may play an important role in decision-making and memory-processing. “One possibility is remembering recent eating boosts the influence this information has on decision-making,” says Suzanne Higgs, lead researcher on the study.

No word yet on what effect remembering previous meals has on removing one’s hideous pelt.

Though there are fewer Muppets references, New Scientist has more details. Humor-blogs.com is also covered in blue fur. Anyone else think the cookie monster might have some serious food issues? And yes, I am dieting.

The journey back to the Thunka Grunkas had been a long and difficult one, but Thag had finally returned from his sabbatical with the Drunka Grunkas, learning how to make beer.

Along with this new technology, Thag also returned with the willowy and beautiful Twigla, his new mate.

Naturally, Thag had been somewhat concerned with how his old mate, Onga, was going to take this news. But he needn’t have worried. She had already moved on, mating with one of the most ancient Elders, Methusalag. This was a mating of convenience, really. Methusalag needed someone to take care of him in his dotage, and Onga was still making grunties with the Shaman, Weasel-Scratch-Face-Brother.

So at first, all was well. He and Twigla settled in quickly — Thag returned to his post as leader of the hunters, and at the same time, started his first batch of beer. Twigla quickly befriended the luscious Vonga, and her mate, Fonzag, had become a decent hunter whom Thag thought could someday lead the others. With Thag leading the hunters and providing beer, the tribe prospered.

But in his absence, the Shaman had solidified his hold on the tribe’s religious development.

“It is the will of the gods that Thag has returned to the Thunka Grunkas, and their divine wisdom makes him brew us beer. They lead him to the mammoth,” Weasel-Scratch-Face-Brother told the assembled tribe the night when everyone enjoyed the first batch of Thag’s beer.

“What?” Thag asked.

“It is not your own will, but that of the gods, that brings these good things to us.”

“You not want me go to Drunka tribe. Thag convince Elders.”

“This too was the will of the gods.”

“Where be gods?”

“All around us, Thag. Do you not see their work when the wind blows, when the rain falls? This too is their will.”

“Thag see wind. Rain. Grok no gods.”

Thag had enjoyed perhaps too many bowls of his first brew, and was feeling less inhibited than normal.

Fonzag had also had quite a few. “Aaay! Let’s be cool.”

“What mean?” Thag asked.

“Not sure, but he is the Shaman,” Fonzag said.

“You should listen to your best hunter,” the Shaman said, “he understands it is the will of the gods that rules, not our own mortal desires.”

“Thag make own decisions,” Thag insisted as he stood up.

“No, it is an illusion. You just feel like you make your own decisions. See, you think that you made yourself stand, when in fact it was an impulse sent to you by the gods. But don’t feel down about it, Thag. A man of limited perception cannot see the will of the gods around him. That is why the Grunkas need the Shaman. Otherwise, we’d be guided by idiots like yourself.”

Thag looked thoughtful for a moment, and pretended to move away from the shaman. Then he hauled back his hunter’s fist, and punched Weasel-Scratch-Face-Brother in the nose (with enough force to break said proboscis, and knock the smug Shaman off his feet).

Weasel-Scratch-Face-Brother moaned in pain, and Methusalag said, “Thag, how could you?”

“Not Thag’s fault,” Thag explained. “It will of gods.”

Thag’s year with the Drunka Grunka was drawing to a close, and he was almost ready to head back to his own tribe, the Thunka Grunkas.

His relationship with the slender and beautiful Twigla was blossoming, and his artwork was a major triumph, despite the many critics within the Elder’s council of the Drunka Grunkas. They even liked the cow, though they were most excited about Thag’s surrealistic depiction of a mammoth stomping a shaman to death. At first, the Drunka Grunka shaman, Cave-Bear-Bite-Leg-Brother, had objected to the depiction, but then Thag explained:

“Him not good shaman. Him shaman of Thunka Grunkas, Weasel-Scratch-Face-Brother.”

“Why don’t you like your shaman, Thag?”

“Him seduce Thag’s mate. Him demote Thag from leading hunters. Many hunters die without Thag lead them,” Thag amplified. “Him big phallus with ears.”

“Ah,” Cave-Bear-Bite-Leg-Brother said. “I grok.”

When the mural was finished, the Drunka Grunkas planned a festival to celebrate the artwork. A special brewing of the Drunka Grunka specialty, a delectable potage they called ‘beer’.

Thag had noticed that many of the Drunka Grunkas got quite chatty once they’d had a few bowls of their “beer”; in his experience, Thag was used to men not talking much, while the women of the tribe did most of the gossiping, gabbing, and generally keeping the lines of communication open within the tribe.

Because they had beer to supply calories, the Drunka Grunka men didn’t need to spend quite as much time hunting; in fact, they seemed to spend as much time hanging out talking as the women did.

On the other hand, the people of the Drunka Grunkas had noticed that Thag was laconic at best, and positively taciturn at worst. The Elders sent the shaman to find out why.

“You don’t talk much, do you Thag? But from your artwork, it’s clear you have a rich inner life. Why don’t you share it more?”

“Thag say something once, why say again?”

“But it would be nice if you could explain your artwork to some of the Grunkas that don’t get your art.”

Thag shrugged. “They not grok, Thag not make them grok.”

“But it would be –”

“Thag let art speak for itself,” Thag interrupted. “Besides, Thag go back Thunka Grunkas soon. He not be here to explain.”

“Fair enough Thag. When do you think you’ll be leaving?”

“Ah, soon. But now, Thag have something he do want talk about.”

“Oh, really?”

“Twigla,” Thag said, raising his eyebrows. “Her come with Thag?”

“Does she want to?”

“Yes. Her grok Thag.”

“Well, that will get tongues wagging around here; even more than usual,” said Cave-Bear-Bite-Leg-Brother. “Let’s have a beer and we can discuss it with the other Elders.”

“Thag talk on this. Yes!”

Forget the subprime mortgages crisis, every market disaster can be blamed on bad chemicals.

Bad man-chemicals to be specific. New research from the University of Cambridge shows that the economy is ravaged by the whim of the testosterone flowing through traders’ veins.

“The popular view is that experienced traders can control their emotions,” on of the lead researchers, John Coates says, “but in fact their endocrine systems are on fire.”

The scientists discovered that as traders made more money, their testosterone levels rose. So, lots of testosterone equals making lots of money, and it’s good for the economy, right?

Uh, unfortunately, as the honcho-hormones run rampant, this leads to overly aggressive (and bad) decisions. Thence the crash, and this causes elevated levels of cortisol, which causes “shrinkage of the prefrontal cortex and hippocampus, brain regions associated with decision making and factual memory,” the researchers say.

So this is the process:
a) testosterone leads to making money
b) making money generates more testosterone
c) too much testosterone causes bad decision making
d) this causes a crash, and then the brain shrinks, leading to
f) learned helplessness, fear, loathing, rivers of fire and a meltdown of the markets.

So I guess it’s time to let women on the trading floor, eh?

Thag’s sabbatical with the Drunka Grunka tribe was not as idyllic as he thought it was going to be, but on the whole, he was quite enjoying his stay.

First of all, the Drunka Grunkas had invented a delectable potage they called “beer” and it was good stuff. He’d already learned all he could about making it himself, and had even come up with the innovation of adding a plant to the mix that gave the “beer” an extra something. (The Drunka headman in charge of the beer called it “hops”.)

Then there was Twigla, who was beautiful and clearly was falling in love with Thag. Sure, she didn’t have the impressive bottom that the Drunka Grunkas valued so much in their women, but Thag was a Thunka Grunka, and they valued size in the top and the front.

But the Elders were driving him crazy.

In exchange for learning the secrets of making beer, Thag had agreed to paint the Drunka Grunkas a mural (and show his artistic techniques to anyone who was interested).

“You should make the next bull bigger,” Cave-Bear-Bite-Leg-Brother told him. On the whole, the Drunka shaman was much nicer than Weasel-Scratch-Face-Brother, but he still had his own theories on art.

“And it should have an extra set of horns,” insisted Critarg, one of the Elders.

“Yes. Extra horns!” the shaman said enthusiastically.

“I think six sets would be appropriate,” suggested Critarg.

Thag sighed and continued painting. He drew the outline of a very small cow.

“That’s a cow!” Critarg shouted in horror.

“Cow good,” Thag said. “Some Grunkas drink its milk.”

“Not Drunka Grunkas. We only drink beer and water,” explained the shaman. “We don’t need pictures of cows.”

“Cows good,” Thag said, “me grok cow. Cow stay.”

Critarg threw up his arms and said, “I’m going to get the council.”

Just then Twigla walked by, waggling her firm, tiny bottom. Thag smiled at her, and continued smiling, even when the shaman, Cave-Bear-Bite-Leg-Brother said, “what if we draw a representation of the Sky God as a kind of super-sized Cave Bear with a lightning bolt-shaped phallus?”

Here’s the science of Reactance. And here is another group who might not know art, but who know what they like.

The trip back to the Drunka Grunka’s lands would be a long one — of all the Grunka tribes, the Drunkas lived the farthest away from the place of the Great Gathering.

But Thag was happy. For at least one season he would be free of his mate’s incessant nagging, not to mention her infidelities. And he wasn’t only leaving the frustrations of Onga behind — for many turnings of the moon, Thag would be free of the annoying shaman, Weasel-Scratch-Face-Brother.

He was traveling back to the Drunka Grunka homelands to learn the art of making the delectable new beverage, beer. In exchange, Thag was going to paint a magnificent cave mural for them. So while he might be leaving his own tribe, the Thunka Grunkas behind, he was starting to see that there would be no shortage of behinds.

For some reason, the Drunka Grunka women were blessed with an overabundance of fundament — they looked like a herd of mammoth from the back — and it wasn’t until their second week on the trail that he learned why.

Twigla was a beautiful young Drunka Grunka woman, who was without a mate, and one evening as the Drunkas bedded down in their sleeping furs — most of them were paired off — Thag noticed that Twigla was unmated, and sad. In fact, she sat on a boulder at the edge of their campsite, watching the moon rise, a few tears glistening in the silvery light.

“Why Twigla sad?” he asked her as he joined her on the boulder.

“Twigla not have mate. Twigla lonely.”

Thag was intrigued, especially to hear that she had the same command of the Grunka tongue as he did.

“Why Twigla not have mate?” he asked. “Twigla beauty.”

“Thag nice caveman. But not true. Twigla have small bottom.”

“But shapely,” Thag observed, hoping he did not overstep his place as a guest of the Drunka Grunkas.

“Thag think so?”

“Shapely!” he grunted.

“But much junk admired by Drunka Grunkas. Big butts men get!” she wailed.

“Not grok,” Thag grunted. “Twigla beauty.”

She stopped sniffling and wrapped her arm around his. “Me glad Thag learn make beer,” she sighed.

The sabbatical was looking better and better.

Thag really was starting to enjoy the Grunka gathering. His mate, Onga, was behaving herself, and even the new religion of his tribe’s shaman, Weasel-Scratch-Face-Brother wasn’t bothering him anymore.

Every fifth or sixth summer, depending on the position of the stars, all of the Grunka clans would gather and share their stories, swap items (sometimes mates too) and have a bit of a prehistoric party.

As part of the swapping, Thag hoped to learn to make a new drink invented by the Drunka Grunkas; a delectable potage they called “beer”. He had tried to exchange his mate, Onga, for this training, but alas, even the most inebriated tribe in the Grunka clan had heard of her infidelities and general shrewishness. Instead, he agreed to travel home with the Drunka Grunkas and do a special cave painting for them.

He just had to get the Elders of his tribe, the Thunka Grunkas, to agree.

“So why do you want to return with the Drunka tribe when the Gathering ends?” their most ancient and wise Elder, Methusalag, asked him.

“Thag want learn make beer.”

“What is beer?”

Thag had brought a skin of it around, and shared it with the Elder Council. Methusalag drank first.

“But Thag, you are the leader of our hunters. You will be gone for turning of many seasons,” said Frettag, the Elder’s biggest worrier. “You best hunter. Thunka needs you.”

The skin came to Frettag, and he smiled. “Perhaps this is worth the effort. We think on it.”

The next day they met again, intending to let Thag leave.

“No! Thag should not leave!” Weasel-Scratch-Face-Brother told the assembled Elders. “I have a new drink too, given to me in exchange for the wisdom I have learned about the Gods.”

Thag was surprised to see the Shaman. He had spent most of the Gathering in conference with the other “wise” ones of the Grunka clan, talking about the new idea of “gods” –supernatural beings who controlled the elements, and who, naturally, could only communicate with a shaman. When not discussing this nonsense, they spent the rest of the time drumming, chanting and eating mushrooms that made them act even sillier than this new drink, “beer”.

Weasel-Scratch-Face-Brother passed around a skin filled with a white substance, that didn’t taste as good as the beer, but did have its own appeal.

“It comes from an animal that can be tamed and even eaten,” the Shaman said. “It called cow.”

“This drink does not have the same effect on your head,” Methusalag said as he sampled the milk.

“But cow-juice can come all year. All you have to feed the cow is grass,” the Shaman said.

“Hmm. That could be good,” the ancient Elder agreed.

“Beer come from grass too!” Thag interjected. “Need no cow, just how make it!”

“We understand Thag. We will think on it another night, and tell you our answer tomorrow.”

Weasel-Scratch-Face-Brother crossed his arms and grinned smugly at Thag. The hunter didn’t even understand why the Shaman wanted him around. He’d been trying to get rid of him for years, so that he could breed with Onga. Of course, he’d had to live with her constant complaints too.

That night, most of the Elder’s Council was struck down by horrific fits of gas and diarrhea; it was later known in Grunka legend as the Night of Many Pongs.

“Thag not like milk!” Thag groaned to Onga as he clutched his bloated belly. “Me drink only beer.”

In the morning, the Elders told Thag he could go.

Read the early Thag stories here…>

Something was rotten within the Thunka Glunka Clan, and the putrid stench swirled around the vortex that was Thag.

The previously unassuming Thag.

Thag was a competent hunter, a low-key leader, once a loving partner (before his mate Onga had left him for the clan’s shaman, Weasel-Scratch-Face-Brother) and a burgeoning artist.

It was Thag’s art that had caused the stench storm; in particular, a satirical painting showing how Dubyag — the leader imposed on the tribe’s hunters — had screwed the mammoth, so to speak. Thag just didn’t blame Dubyag, who was ambitious beyond his abilities. He blamed Bushenor, an influential Elder who had foisted the incompetent Dubyag on the hunters.

It had been a political decision that had caused the hunters dearly, and would, in turn, cause much hardship over the coming winter for the whole tribe. Some would die for lack of food. Just like the hunters who had met their demise in a poorly conceived hunt of a rutting (and enraged) wooly mammoth.</
