Monday evening study hall

I think we should repent for all our Friday and Sunday carousing, so that we can do it again this weekend with a clear conscience.

So welcome to The Universe 101.

Facts presented here need not be useful or true, or even interesting. They just need to build character. Or something.

Me first.

The opposite of absolute zero (0 degrees Kelvin) is Planck's Temperature, 10^32 degrees Kelvin, the hottest possible temperature. I'm not sure how they figured that out, but it sounds pretty danged hot.

Robert Lustig: Absolutely, we're being poisoned to death, that's a very strong statement but I think we can back it up with very clear scientific evidence.

Norman Swan: Are you postulating here a fructose conspiracy, the way the tobacco industry had a nicotine conspiracy?

Robert Lustig: Well I can't call it a conspiracy per se. I certainly know, and they certainly know that they sell more of it when they add the fructose to it. That's why it's in there, otherwise why would it be in there? Do they know that this is actually harmful? That's what I don't know. There's no smoking gun, ultimately we found the smoking gun for smoking, you know we found the documents. I'm not prepared to say that about the food companies. I do not know that they know that they are hurting us. However, they definitely know they sell more, and it temporarily coincides with the advent of fructose being added to our diet.
But I TOLD them this would happen if they trade tariffed sucrose out of existence! I told them, I told them, your Coke will taste like crap and you'll be POISONED! Okay, I only said the part about the Coke. But I meant the other part.

^You know, that's really true. Sugar cane is cheap in Mexico, so they still use cane sugar to sweeten drinks there, and the sodapop is so much tastier. And it comes in cute little glass bottles, except in areas where they prefer to serve it to you in a baggie with a straw, so they can get the glass deposit back.

A digeridoo is a traditional instrument made by the indigenous people of Australia. Before European settlement, there were hundreds of languages spoken by different tribes, so of course its name varies from place to place but most non-Aboriginals simply use the name digeridoo.

The digeridoo is customarily only a man's instrument; in traditional Aboriginal society women were forbidden to touch it. It is played at ceremonies and as an accompaniment to dances. Although experienced digeridoo players make it look easy, it requires a lot of skill because all of the sounds must be produced by the player's mouth or throat.

A digeridoo is made from a sapling or small tree that has been hollowed out by termites. It is cut down, the bark is stripped off and any debris removed from the hollow. It is often painted with ochre in traditional patterns personal to the owner. The length of the digeridoo will determine which key it plays in, for example if you had a digeridoo that played in C and you cut some off you might end up with one that plays in G.

^Virginia Tiger Moth? (aka Yellow Bear) Not sure, but I do think it's a moth caterpillar.
-------------------------------------------

Ah, the unexpected side-effects of evolution. It's just sad, how interesting I think this is:

In a study in today's issue of the journal Nature, scientists found that fruit flies are attracted to the taste of carbon dioxide dissolved in water, or what we commonly call the fizz in soda.

The fruit flies use their nosy ability to find food in your kitchen, of course. Yeast and bacteria both produce carbon dioxide (CO2) when they feast, and the chemical dissolves readily in water.

A little moisture, some rotting fruit, and, well, you know what happens next.

Exactly how the flies discern which fruit to go after is not entirely known, but neurobiologist Kristin Scott of the University of California at Berkeley thinks it goes like this:

"Flies seek the right amount of rottenness," Scott explained. "If fruit is only half rotten, producing a little CO2, it's good; if too rotten, it gives off a lot of CO2 and is bad tasting. They seek a balance."

And it might be that humans can taste it, too. See, fruit flies contain similar versions of many human genes. That's why scientists study them so much.

"This research raises the question of whether people also may have the ability to taste carbon dioxide and perhaps other chemicals in food," said study team member James F. Battey of the National Institute on Deafness and Other Communication Disorders. "If this were found to be true, our sense of taste could be even more complex than we realize."

Currently, scientists recognize five tastes in humans: sweet, salty, bitter, sour, and umami (also called savory; it's the taste of glutamate). And there is considerable debate about the existence of a sixth taste receptor for fat, too.

(So, to review, the basic tastes MAY be: sweet, salty, bitter, sour, savory, and rotten.)

this is a "test tube cleaner" bug. You set it loose for 5 minutes in any test tube and it will wipe it completely clean.
