Re:Seems silly
Bacteria and fungus abundantly live on/in organisms with no free water. Such as cheese and bread. They may release water from the organic compounds in which they live, but that is really not the same as needing water. Although you could certainly argue that without the other beings that produced the bread or cheese they wouldn't exist. Which may or may not be valid.
These bacteria and fungi have cells which contain water. The cell structure wouldn't exist without it. That water has to come from somewhere, whether it's by absorption from the environment or by chemical breakdown of food... or gifted in part by an ancestor via mitosis.
I think you are underestimating the amount of water present in a typical loaf of bread, or for that matter, in a typical cheese. (Hard cheeses might have little water in them, but there are certainly different types of cheese.) The fungi and bacteria are also free to fix moisture from the atmosphere, even if none can be obtained from the food on which they live.
If the cells contain water, then water is a necessity for life, because the chemical reactions within the cell require it. I think you're playing a little fast and loose with your definitions and your reasoning here. Or maybe you're engaging in semantic games. Either way, what you're doing isn't science.
So, I stand on the water is not a necessary requirement for life. [...] I'm not a biologist, just casual reader of such topics.
So you have an opinion that you hold dearly in the face of evidence to the contrary, but you admit that you have no actual scientific credentials in this field, and that you're basically a dilletante?
But let me go on...
When I said alcohol, I was including the entire classification of alcohols, not simply your sterilizing ethanol.
Actually, all alcohols are toxic to cellular life -- some are simply more toxic than others. Ethanol can be tolerated by humans because we have enzymes that can metabolize it relatively quickly, but humans can and have died from ethanol poisoning. Obviously, single-celled organisms don't have the body mass of a large animal to render the absorbed alcohol dilute and spread damage around.
If you want to understand why alcohol makes a crappy solvent for life as we know it (and that includes all cellular life on this planet), you need to understand the biochemistry. I found a couple decent resources here and here which explain this in enough detail to get you started.
As for your rogues gallery of bacteria, I would point out that in no case have you provided the name of a single organism that can survive without water. (No, even Deinococcus peraridilitoris requires some water. Desert sand may be pretty darned dry, but moisture does collect at night, and during the cold season. A bacterium, or even a colony of bacteria, doesn't need much.) That they are extremophiles only proves that life can invade just about any niche, but these examples do nothing to blow away any of the basic requirements.
There's another organism I've read about and seen microphotos of in a NOVA science program -- sorry, don't have a specific scientific name handy, but it lives in small pockets inside rocks that are extracted from miles-deep bore holes. You can find a good jumping-off point here These bacteria live off the chemical energy derived from slowly dissolving the minerals of the rock around them, and they divide very slowly -- on the order of once every 100 years, perhaps longer. Even here, all of the basic given requirements (yes, even water) hold true and are met.

Location choice is proximity-based?
Perhaps the specimens and anticipated case-load for this lab are expected to come primarily from the surrounding areas. Bringing the lab close to where the incidents of interest are likely to occur offer some advantages. I know that whenever most of use hear of a Bio lab we immediately assume that it is meant for production of pathogens, but numerous such labs are actually diagnostic in nature. For example, many states have a Plant Disease Diagnostic Laboratory (such as this one).
Sure you could probably quarantine and relocate an entire herd to a remote lab in Alaska but it could be better to move them to a facility much closer. But even if it were placed in Alaska people would then become concerned about protecting the wildlife and how the facility would cope with the freeze hazards. No place would be good enough.

Re:iirc
I was basing that on what my calculus teacher told me; that Newton called it "Leibniz' Rule" as a sort of mocking joke.
However, it would appear Leibniz did correct his mistake, after ten days. He did make the mistake at first but maybe it was just one of carelessness (see these websites and their citations if needed: http://www.math.tamu.edu/~dallen/history/calc1/calc1.html; http://www.math.usma.edu/people/rickey/hm/CalcNotes/ProductRule.pdf).
At any rate, I maintain that it's definitely possible to be able to compute integrals and not understand the concepts; as it is possible to understand the concepts and not be able to compute (difficult) integrals. After all, no practitioner living today computes integrals the same way as Newton did, except perhaps as an esoteric exercise. Computation is a skill which is partially orthogonal to understanding.

Re:Microsoft Begs Win 7 Testers To Clean Install

There are literally millions of unix scripts, programs, and utilities for Linux. (...)Half of the links on that list don't seem to exist (anymore). It's sourceforge-effect, which always comes into play when looking for non-standard Linux software: most of what you find is gone, no longer maintained, bugged, outdated and/or useless. If you actually find something usefull, the next hurdle is the compilation and the dependencies. With Linux you seem to have two choices: limit yourself to the software available in the distro's package manager, or fire up your terminal and prepare for some sweet hours of tinkering. Altough i don't mind the tinkering (or otherwise I wouldn't be running Linux), it is not an option for most users. So basically, the set of available software for Linux-users is rather limited, especially when you are looking for non-development related stuff.

Re:UNDERGROUND CITIES
Everyone assumes one can grow plants in any old dirt. You not only need soil; but more importantly, you need the proper microbiology in the soil for the plants you are growing. Unfortunately, too many people in charge of things are more concerned with proving the existence of life on other planets then the advancement of humanity. If they would be replaced by people less concerned with ideology and more concerned with the future we would be able to take microbiology to mars. IMHO Until someone can figure out a way to prove to an ideologist something that can't be proven, or get rid of ideologists all together, Mars colonies will never happen.

Assert your rights
I have discussed this issue with some friends who seem to believe that Obama will reverse the current warrantless surveillance practices. If history is to serve as a guide, it seems clear that he will not. I am convinced that contacting our legislators and voting for Democrats are two of the least effective means of protecting our rights. Indeed, the most effective way of protecting our rights is by asserting them. We as Americans have the responsibility of actively protecting our rights, rather than depending on the ineptitude and conflicted interests of our elected officials. This is why I propose not only opportunistic encryption, but also what I call gratuitous encryption. This means the ubiquitous use and advocacy of PGP, SSH, SSL, VPNs, tor, full disk encryption, and every other tool we have at our disposal.
Check out this page for ways to assert your rights.

demand for natural gas likely to increase
I don't know if anyone has checked, but natural gas ain't exactly cheap either.
It might currently be expensive, but that's based on current demand & supply. Domestic oil companies recognize the possible vast availability of natural gas in the Gulf of Mexico. While other energy sources remained cheap, there was no incentive to develop infrastructure to harvest domestic natural gas on a large scale. Now that petroleum is expensive, natural gas is likely to draw a lot more attention both in demand which will spur development of supply.

Re:DoubtfulThere was news recently that the George W. Bush Library foundation (whatever its real name is, I'm unsure of) was having a great deal of difficulty with domain name squatters who had stolen every possible website they would want to put his library's web page on.
Sounds like bullshit to me. See Contacting the Presidential Libraries. It lists the addresses of all the presidential libraries. eg:
- Herbert Hoover http://hoover.archives.gov/
- Franklin D. Roosevelt http://www.fdrlibrary.marist.edu/
- Harry S. Truman http://www.trumanlibrary.org/
- Dwight D. Eisenhower http://eisenhower.archives.gov/
- George H Bush http://bushlibrary.tamu.edu/
Most are
.edu or .gov, which squatters can't use at all. I guess it's because everyone thinks the have to have a .com. Thus all the presidential candidates have an entirely inappropriate .com site instead of .org for their campaign, for instance. So they can't get "GWBushLibrary.com". Too fucking bad. Get GWBush.archives.gov or a subdomain of whatever institution manages it (probably a .edu). -
Re:Boo fucking Hoo
The rights that are spelled on in law, dumbass.
Do you truly believe law defines morality?
That's right -- it's illegal to eat onions in certain cities and at certain hours. I assert that I have the right to eat onions whenever the fuck I want.
How about we talk about rights, and not laws?
Here is some more reading for you:
Ah, yes, that would be this right. Specifically:
(c) Prohibition on Circumvention of the System. No person shall import, manufacture, or distribute any device, or offer or perform any service, the primary purpose or effect of which is to avoid, bypass, remove, deactivate, or otherwise circumvent any program or circuit which implements, in whole or in part, a system described in subsection (a).
Is that the "right" you're defending? The right to require that no one ever circumvent your copy protection, no matter what the reason? Does it ever occur to you that there might be a legitimate reason?

Re:One thing always missing from such stories...
It's not news that an old system was replaced by a new system. It is interesting that an old supercomputer wasn't replaced by a new supercomputer; a cluster of cheap commodity systems does the job just as well when you don't need real-time performance. This sort of creative use of PCs is what drove SGI into bankruptcy and irrelevance.
This Philipine newspaper story fills in some important details missing from the Australian PC News article: the age of the SGI system (10 years) and the reason it was costing so much to run (expensive to get application support for IRIX, an OS that hasn't had a major update in the same 10-year period).
This last issue is what really killed the SGI system: not its age (these big installations are often around for decades), but the fact that only a few people are working on SGI platforms any more, and those that do can command premium prices. If the system had been from Sun, HP, or IBM, or any company with an OS still under active development, it might have been cost effective to keep it in place. This is particularly relevant on Slashdot, where we're always hearing from folks who just don't understand why there isn't better application support for their favorite platform.
I'm still curious as to what specific SGI system got junked. Best guess: a low-end Origin. -

Re:Very Good...
Well, you get up to 21 pounds of CO2 from a pound of crude oil - a 21:1 increase in "stuff". This sponge apparently can do a 1:83 reverse, so the whole system appears to be a 21:83 savings in space underground. Why not pump it right back into the ground?
That is so wrong that I am forced to suspend your Slashdot license.
First, that page page doesn't say "pound of crude oil"; it says "gallon". That's like 7.5 pounds of oil. So that's a 3x increase in stuff. (Which some would call "mass".) Then these crystals do 1:83 in volume, but more like 10:11 in mass. So to get rid of your pound of crude oil, you'd need about 30 pounds of these crystals.
Please go study Dimensional Analysis (aka the unit-factor method or the factor-label method). Once you have mastered that, you will be permitted to post on science-y topics again. -

Hatshepsut and Thutmosis
Hatshepsut is a very interesting historical figure.
She reigned during Egypt's New Kingdom, a little after Ahmose drove out the Asiatic Hyksos from the north, and unifying Egypt again under native rule, and bringing Egypt to it final age of glory in ancient times.
She was the Pharoah of Egypt, marrying her half brother, Thutmosis II (a common practice then), who had a son, Thutmosis III by a lesser wife, and co-ruled with her nephew.
She sent ships and explorers to the Land of Punt (thought to be Somalia).
The explorers who returned recorded their findings on the walls of her temple (El Deir El Bahari: modern name: the Northen Monastery, original "Djeser djeseru").
You can see amazing details of Red Sea fauna there, such as spiny lobster, squid and other creatures.
There are inscriptions of natives from Africa too in meticulous detail, as well as their dwellings (thatched huts). There is even an obese queen from Punt with some disfigurement.
You can see a replica of the inscriptions at the Royal Ontario Museum (ROM) in Toronto (rather there was big room full of that when I was there a few years ago).
So, when Thutmosis III finally took over, he went through a campaign of removing her memory from history. Although being his aunt, she was also his step mother, and God knows what relationship they had when his father was alive.
Although other Pharoahs did this regularly, it was not targeted towards any particular one specifically, but rather an attempt to claim the monuments of predecessors as his own.
Her statues were toppled in wells (where they were discovered in the 19th century).

bananas
That was a very interesting post, though prone to exaggeration. Your attitude seems to be that if American's change a foreign dish, we get credit for it but if
someone else changes an American dish, we still get credit.
Bananas did not originate from Hawaii, though bananas were probably introduced there between 500 and 700AD.
According to wikipedia: "They are native to the tropical region of Southeast Asia, the Malay Archipelago, and Australia."
One of my ancestors, an American by the name of Minor Cooper Keith, was responsible for the global banana trade (before it became exploitative), starting around 1873. Although a few banannas had been imported to the mainland US, and probably other areas like Europe as well, by sailors, they were something that you would only eat on a dare (imagine a banana after a multi-month sea voyage). He created an enormous infrastructure to bring these highly perishable fruits to the US from Central America, including the worlds first fleet of refrigerated steamships and dedicated ports to take the fruit quickly (under 60 hours) from harvest to hold. The railroad express shipment within the US had to be orchestrated and retailers had to be specially trained in how to handle and ripen the fruit. He discovered the bananas while building the first transcontinental railroad (before the panama canal) across Central America, along with his Uncle Henry Meiggs who built the first railroad in Chile. Meiggs died during the building of the transcontinental railroad along with around 4000 people (mostly American's from New Orleans) building the railroad through territory the natives were wisely afraid to visit. The workers from the US did not follow recommended safety precautions
but workers who were imported from Barbados survived to complete the railroad. The fruit company they founded has been known over the years as United
Fruit Company, United Brands Company, and Chiquita Brands International and has had a checkered history since Keith's death. Keith himself meddled in
the politics of Costa Rica backing benevolent dictators during the country's transition to the first stable democracy (he married the daughter of the
first president) in the region (other attempts to transition to democracy in the region, which was unaccustomed to citizen participation, were unsuccessful
and bloody). He refinanced the debts of several Central American countries, built hospitals, schools, and railroads throughout the region, and paid
workers enough to get ahead (double what other workers in the region were paid).
http://www.freelabs.com/~whitis/clan/empire.html
Given that bananas existed for well over a thousand years in many parts of the world before Keith introduced them to Europe/America, I suspect that there are
many banana dishes that are not of American origin. Likewise, although the tomato originated in South America and was common in the US (but thought poisonous
before Jefferson rehabilitated it here), the tomato's history in England dates to around 1590, around the 18th century in France, and around 1550 in Italy. By
the mid 18th century, tomato consumption in Italy was widespread. So I am sure that the Italian's and others would take exception to the notion that anything
with tomatoes not of hispanic origin is created here. http://plantanswers.tamu.edu/publications/vegetabl etravelers/tomato.html
The American hot dog is a perversion of the german Wurst (pronounced Vurst) or Wiener, though the National Hot dog council, according to wikipedia, credits a butcher in Germany, not an American, with the invention of the Hot Dog (the bland miniature version).
The Hawaiians had a very healthy diet before western influence, now the Hawaiians are the highest per-capita consumers of Hormel products (or so I was told
