Yes, ice does expand when it freezes. In the ocean this ice will end up floating, no net change in sea level. The change in sea level comes from the melting of continental ice... ice which was not previously buoyed up by liquid water. This is the stuff that will increase water volumes.
I also remember at one time calculating the rise in sea level from thermal expansion as the oceans warm up. I recall that even one degree change would have a measurable effect on ocean levels. But this was also assuming that the oceans warmed evenly, and was a pretty rough guesstimate on average ocean depth.
Maybe because some people might be allergic to a totally different protein than they engineered out. The company then gets sued for false advertising or something...
I can't tell you how my bad eyes might bennefit mankind
For one, near sighted people are a lot better at using a microscope. The lens of an eye acts as, you guessed it, a lens. Being nearsighted means that an object has to be closer to your eye to focus on it. This essentially translates into a larger image cast on your retina for a given size object.
Conversely, a farsighted person would be better at using a telescope.
The grandparent was saying that he was prescribed an antibiotic for a fungal infection. Antibiotics have no to little direct effect on fungi. They basically just kill off bacteria, which in some cases would remove competition pressures on the fungi, allowing them to flourish even more. BR
Just think about the fact that a large class of antibiotics are derived (at least originally) from fungi (think penicillin.) Fungi produce these antibiotics to kill the bacteria which compete with/harm the fungi themselves.
Ehh... Americans have been ruled by fear for a long time.
Commercials: From showing tiny bacteria magnified with spooky music to pitch Lysol to the SUV being pushed as a sefer vehicle for the driver (even though its been shown time and time again to actually be more dangerous.) Fear of social stigma is often used with the "don't be the last one on your block to own..." sales pitch.
The News. every night you hear "we have the inside scoop on XYZ product and how it can kill your children in the middle of the night and then proceed to use your toilet and leave the seat up... duhn duhn duhn." Or whenever the weather is even mildly not perfect, you get huge storm adviseries warning people not to even try venturing outside of the house. You should stay inside where it is nice and safe and watch TV instead.
Warning labels: Our hyperlitigious society has forced manufacturers to put warning labels on everything, from multivitamins to Qtips. Come on... even music with naughty words has to have a warning label on it.
Seeing every single thing around you as a blatant risk to your safety and well being HAS to be psychologically traumatizing. No wonder why the American people are known for violent crime. Which ironically, is something that the media will then turn around and use to its advantage in a further cyle of fearmongering. It makes sense that political candidates are doing it too. They have been for a long time, a senator McCarthy comes to mind. Supposedly he didn't even care that much about Communism. He just wanted an issue that would strike enough fear into the hearts of Americans to give him power.
If you put personal property on the desk (pictures of girlfriends, etc) that should be a firable offense too
First of all, there is not likely to be a policy preventing putting pictures of loved ones on your desk, while there was likely a policy disallowing installation of unaproved software.
Your argument is also an invailid slippery slope style argument. And, IMO, it is a weak slippery slope at that, because it could slip the other way, too. If you are allowed to install SETI on your computer, what prevents you from installing file sharing programs to download your favorite mp3s? Games off the web that have not been checked for viruses and spyware/etc? There is likely a policy preventing unauthorized software for this reason, and if this is the case, then installing SETI violated that policy.
And how about another slippery slope? I can put pictures on my desk, so it must be okay to nail them to the wall. Or photocopy them using the companies machine and paper and plaster them up in the lobby. This may seem like an unrelated scenario, but according to the article SETI was installed on a server, not his "personal" workstation.
Now, the public insult from the department head about the employees intelligence is another story completely and, at the very least unprofessional, at the worst libelous and asking for a lawsuit. Especially inappropriate coming from the department of job and family services, a government entity which would likely interact with people involved in wrongful firings.
Having long been a fan of pockets, I have come to realize that pockets built into your pants are not an ideal solution. Not very configurable, and you have to pull out your stuff whenver you change pants. This is where ALICE gear can come in oh so useful.
In Firefox 1.0 Pre with some mouse gesture extensions installed (Don't remember offhand which ones) I can:
1) cycle through tabs by rolling the scroll wheel when the cursor is over the tabs.
2) back page by right click, move mouse left.
3) Forward page by right click, move mouse right.
4) And CTRL+Mousewheel does zoom in Firefox for me, although it does not zoom as well as Opera, in my opinion. Basically just changes text size, no images zooming, formatting within frames or CSS gets kinda wierd. So I guess You still do have the zooming thing. Which isn't much of a deal for me in particular, but for people who's vision is going and would normally need glasses for reading, this is actually a very useful feature. More usable than most ADA hacks I've seen
But in my experience, Mozilla just has a more polished feel. This is something that very pieces of OSS really seem to get right, and I congratulate the Mozilla team on working this through. No cryptic configuration files (I may be able to properly configure one of these, but our Aunt Tillie may have some more problems with it.) I enjoy the light footprint that the browser takes up on my screen space, The ad-blocking and pop-up/pop-under general annoyance control are VERY effective, and best of all, just about every website (with the exception of SlashDot... I've heard a fair number of people complain about this) that I visit regularly seems to render properly, and if it doesn't I usually think twice about trying to load it up in a different browser, because often times that means some IE hook for delivering unwanted (in my mind) advertising content to me.
Oh, and one thing that FireFox shares with Opera is how fast pages seem to load. Sure, I'm theoretically limited by the file throughput, and don't have anything to back up my observations, but FireFox and Opera (Along with Mozilla to a lesser extent) just FEEL fast when rendering pages. I remember this effect MORESO back when I was on dialup. I don't know if Mozillas/Opera try to start rendering before the whole html file is downloaded, or if they do this with displaying partially loaded images, but the feel was just somehow much much faster.
As an alcohol/caffeine combination fan, I can tell you that you still get drunk, without the sleepiness. Pretty much the same thing during the night out, just a little less sleepiness.
Interesting thing is that the alcohol breaks down in your body a little quicker than the caffeine. Traditionally in the morning after, people really don't feel too good. After a night of Red Bull and vodka (my drink of choice... absolut with sugar free redbull) when 7:00-8:00am rolls around, the alcohol had worn off, but the caffeine is still going strong. So every now and then you just wake up really raring to do something. Anything. Even cleaning the grout in the bathroom tiles. The problem comes when the caffeine wears off around noon or so. Unless the whole morning had been spent downing more caffeine, it becomes sleepy time again. Only moreso.
But this is just the experience that I and a couple of my friends (We're known as the "Thug Posse" after the nickname that we use for RBV's - Thug Passion) have had. YMMV due to differences in metabolism, built up tolerances to caffeine/alcohol, and how heavy you mix your drinks.
And after a night of Thug Passions (Or Thug Lightly as my favorite version is called)I personally do not get hangovers no matter how much I drink. But this only holds true if I don't drink anything else, with the exception of a Jager Bomb or two.
For anyone wants to know the most popular variations among the thug posse:
Thug Classic: Absolut mandarin with regular Red Bull (what got us hooked on Thug passions: tasty the first few times you drink em, but get boring after a while. Tastes sort of like a cross between sweet tarts and Flinstone's chewable vitamins.)
Thug Continental: Absolut Stoli with regular Red Bull. Slightly refined flavor, often a tasty treat.
Thug Lightly: unflavored Absolut with sugar free Red Bull. Don't get the sugar buzz, which can make me quite sick at times, but the sugar free Red Bull just does not seem to mix with flavored vodkas.
And then for the truly HardCore(tm), if your favorite bartender gives you a glass of vodka and then hands you the can, when you go up for the next round and don't need a can, then you can order "Thug, hold the passion." And hopefully your bartender knows which flavor vodka you choose.
Not that I actually condone mixing alcohol and caffeine, or even drinking alcohol excessively. And if you do either of the two, please folks, just don't drive. It aint worth it. If you plan on drinking, make plans beforehand. It seems that most people that I know get behind the wheel after drinking too much because they don't want to deal with the hassle of getting their car in the morning. And if you haven't been drinking, and your friend who has tries to drive home, offer to drive their car home for them. Then just crash at their place till the morning or find your own way home or back to your car. They'll thank you in the morning.
I agree that a cat must have a chance to explore. It is just fine exploring under your bed, in a paper bag just brought in, etc. And the hunting instinct can be more than compensated for by play and attention. Cats that are never allowed to roam free outside never really have much of a desire to.
The fact is that cats that allowed to roam free have an average life expectancy of 3 years as opposed to 15-18 years for indoor only cats. House cats are domesticated animals. Many of the traits which help them survive in the wild have been bred out over thousands of years. Even wild cats which still have all of their instincts have no way of dealing with traffic, the number of poisons that are easiily found in the city and the cruelty that can be inflicted on them by other humans.
And if you are still convinced that your cat needs to go outside, please make sure that it is spayed or neutered. Remember that in seven years one female cat and her offspring can produce 420,000 cats. Because of this shelters are forced to euthanize millions of cats anually. These are people who love animals enough to make taking care of them a career, who have to kill cats each and every day because people are unwilling to spay/neuter and keep their cats locked in the house.
However, I do agree with you 100% on declawing. It is indeed cruel, and there are ways to cope with the instinct and redirect it. And from personal experience working in shelters, a cat poses a much greater risk to people after it has been declawed, since the only weapon it has left to use when frightened is its teeth.
And as long as I am ranting on the topic of humane treatment of animals: If you are considering adopting a cat (or any other animal) please look into the amount of actual work it is and decide if you are capable of providing for the animals needs. If you do decide to bring an animal into your life, please please please consider adopting one from the local shelter or a breed specific rescue organization. Many pet stores and ads in the paper often get their animals throughvery cruelsources. There are too many perfect animals waiting for homes to support the cruel trade of pets as product. And paying alot for a pet through a breeder that you do not know does nothing to guarantee the health and condition of that animal.

While this would be nice, the process of using hydrogen as a fuel is realistically not that efficient. First of all, electrolysis of water to hydrogen gas + oxygen is only about 30% efficient, if I recall.
Also, hydrogen is quite difficult to store. Hydrogen is not very energy dense, meaning that it really can not store a lot of energy for the amount of volume that it takes up, even under fairly high compression. Add to this that compressed hydrogen is relatively dangerous and requires expensive tanks, this adds to the cost. Even morseo if the hydrogen is to be used for transportation.
However, some technical solutions may be found to facilitate storage, or even increase efficiency of electrolysis. The question would come down to this: is it more efficient to drive essentially the whole power grid by wind, storing it as hydrogen (or some other method) in times of excess in order to convert it in lean times, or might it be more effecient to build wind turbines so that at peak power, they provide most of the energy for the power grid, and at other times more easilly stored sources of energy (fossil fuels, bio-diesel, etc) are used to fill in the deficit.
Realistically, if we are to keep increasing our power consumption, we are going to have to utilize as many forms of energy as we can, and use them where they are the most appropriate. In places with steady winds, wind forms can be constructed. Places with very little cloud cover would be ideal for some form of solar energy. Geothermal energy where available. Biodeiesel can be made from waste organic materials, as well as fresh materials (E.G. corn oil + alchohol) grown specifically for that purpose. Nuclear power (both fusion and fission) both have the potential to produce incredible amounts of power, but they both have their drawbacks which may be overcome by technology. And then of course we have the old standby of fossil fuels, but those are a fairly limited resource, and should only be used where absolutely necessary (at least in an ideal situation,) or where the other energy sources are counterindicated for some reason.
And on top of all of this, we will have to develop more efficient ways of doing things. Design cities in a more efficient manner. Of course make vehicles and other tools more efficient through technology and consumer choices. Provide incentives for using electricity in off peak hours of power consumption (or rather penalties for using electricity during peak usage periods.)
There does not seem to be one magic bullet for our energy need problems. And I highly doubt that we will find one in our future. The real answer lies in careful evaluation of all the pieces and using every tool available to make the system work, and keep it working for as long as we want to keep society going as we know it. Now, some may question whether we _SHOULD_ keep society growing and growing, but I'll leave that to the philosophers. Or at least a different thread.
No. The FCC law was about an airport authority trying to force its tenants (airline companies) to use the authority's wireless network. The FCC said that only the FCC has the right to tell someone not to use unliscensed spectrum, which is the case here.
While cartilage does not have a cascular system, a small amount of nutrients can get throgh by diffisuion. This allows for very slow repairs. However, for anything that is not very minor, the rate of wear will be greater than the rate of repair.
With the replacement, this would in essence be growing a new organ (or part of one) from immature cells (think stem cells.) IIRC cartilage can basically grow by adding new layers on the outside, where diffision from the surrounding tissue will be quite rapid. This immature cartilage may even has some basic level of vascularization, but I'm not quite sure on that.
So, in essence, you can grow new parts (otherwise you wouldn't be able to grow them in the first place) and cartilage does keep growing slowly. But you are right in that internal cartilage repair is not significant.
Oh, this wouldn't be run on pigeons. KDE is of course working on PenguinRank, in which a flock of penguins (volunteers, naturally) would run the analysis. Although one technical difficulty will be in maintaining the cooling systems necessary to keep the penguins at a comfortably temperature.

I thought Physicists thought they were mathemeticians, who thought they were philosophers, who thought they were sociologists, who thought they were psychologists, who thought the were biologists, who thought they were chemists, who then thought they were physicists...
Yes, zebra mussels do CLEAR the water, but they do not CLEAN it. What they do is they remove all the sediment that other creatures oftem feed on, thus making it unavailable. However, they pass most pollutants right on (except for some heavy metals and such which they bioaccumulate like crazy, poisoning any creatures which then eat them.)
And the clearing of the water actually causes problems in and of itself. There is still a super high nutrient load in the water, and the extra light allowed in causes several noxious weeds to grow out of control, choking out most normal vegetation, destroying habitat several animals use (especially for egg laying) and choke waterways from human navigation.
While their unchecked growth in the wild does cause problens, zebra mussels could make an interesting part of a constructed bioremediation system (at least in waterways which are already infected by the zebras anyways.)

I thought Physicists thought they were mathemeticians, who thought they were philosophers, who thought they were sociologists, who thought they were psychologists, who thought the were biologists, who thought they were chemists, who then thought they were physicists...
Yes, zebra mussels do CLEAR the water, but they do not CLEAN it. What they do is they remove all the sediment that other creatures oftem feed on, thus making it unavailable. However, they pass most pollutants right on (except for some heavy metals and such which they bioaccumulate like crazy, poisoning any creatures which then eat them.)
And the clearing of the water actually causes problems in and of itself. There is still a super high nutrient load in the water, and the extra light allowed in causes several noxious weeds to grow out of control, choking out most normal vegetation, destroying habitat several animals use (especially for egg laying) and choke waterways from human navigation.
While their unchecked growth in the wild does cause problens, zebra mussels could make an interesting part of a constructed bioremediation system (at least in waterways which are already infected by the zebras anyways.)
