Re:Realclimate trolls again?Assuming the measurements are accurate. Arriving at a global mean temperature is voodoo enough, but when you place your surface temperature measuring stations beside air conditioning unit exhaust vents you have to wonder if the temperatures even reflect reality. Most of these stations surveyed have a margin of error in recording temperatures of more than 2C... while your measured catastrophic increase is 0.6C?? Next stop, measuring your member with an unmarked ruler. "Hey, it's about a foot long. Really!!"
I certainly agree that some of the surface measurement sites are situated poorly. However, given that "changes in borehole temperatures (Section 2.3.2), the recession of the glaciers (Section 2.2.5.4), and changes in marine temperature (Section 2.2.2.2), which are not subject to urbanisation, agree well with the instrumental estimates of surface warming over the last century" and that there is no statistically significant difference between the records from rural and urban surface temperature stations ("While there is little difference in the long-term (1880 to 1998) rural (0.70C/century) and full set of station temperature trends (actually less at 0.65C/century), more recent data (1951 to 1989), as cited in Peterson et al. (1999), do suggest a slight divergence in the rural (0.80C/century) and full set of station trends (0.92C/century) However, neither pair of differences is statistically significant.", as detailed in the IPCC report, it doesn't, well, appear to be statistically significant. Oh, and could we omit the petty attempts at vulgar "humor"?
We're now glossing over point 2 and making broad assumptions. Nevermind that "To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today-- 4400 ppm. According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence earth temperatures and global warming." [Source] Hmmm... what's the phrase I'm looking for here... something about correlation and causation.
Perhaps you ought to take a look at this study. I quote: "The answer: This particular ice age didn't begin when CO2 was at its peak -- it began 10 million years earlier, when CO2 levels were at a low." "Taken together, the evidence suggests that the ice began to build up some 10 million years earlier than when volcanoes began pumping the atmosphere full of the CO2 that ended the Ordovician ice age." "Our results are consistent with the notion that CO2 concentrations drive climate."
May want to update your talking points...though I rather suspect you'll regurtitate the same set the next time a climate change discussion comes up here.
" This last one brings us to the ultimate death blow to the global warmers' argument. The warming we've experienced since the last glacial period has brought us grasslands, forests, jungles.... When the next glacial period comes, the planet will be covered mostly by icy tundra and extreme deserts again. Warming has only made this planet MORE habitable to us. I've got 12000 years of proof that warming is good. What do you have to the contrary?"
Dude...are you being deliberately obtuse? It's not just sea levels rising due to glacial melt, though that alone is problematic (though there's this thing called empathy where some humans sympathise with the plights of other humans...something you apparently lack). Potential consequences also include droughts, heat waves, disruption of various ecosystems, increased oceanic acidification due to greater CO2 absorption (up to a limit) and so many others. If you were genuinely interested, I could go into the details.

In other news...Descendants of the former in habitants of Petra are suing for the loss of revenue when their ancestors' city became uninhabitable due to climate change. Defendants in the suit include the Italian Government, citing that two major events under their ancestors' rule were contributing factors in their decline, namely:
- The burning of Christian martyrs by Nero
- The burning of Rome itself under Nero
- The Government of Pompeii for failing to properly mitigate the greenhouse gas footprint of Mount Vesuvius.

Re:Just based on the article
Well, another article is entitled "Inventor Doesn't Dare Say 'Perpetual Motion Machine'", but then quotes him as saying: "What I can say with full confidence is that our system violates the law of conservation of energy". So it's just as much bollocks as any other "free energy device", it's just that he hasn't claimed that the "free energy" is sufficient to run the machine forever.
What I want to know is: why not? If you're going to try to break the laws of thermodynamics, at least try to break them properly! -
I read the article...From another source:
In Heins' machine, he explains that magnetic friction somehow gets turned into a magnetic boost. Working with an electric motor, he attached the drive shaft to a steel rotor with small round magnets lining its outer edges. In this set-up of a simple generator, the rotor would spin so that the magnets passed by a wire coil just in front of them, generating electrical energy.
Then Heins did an experiment: he overloaded the generator to get a current, which typically causes the wire coil to build up a large electromagnetic field. Usually, this kind of electromagnetic field creates an effect called "Back EMF" due to the so-called Lenz's law. The effect should repel the spinning magnets on the rotor, and slow them down until the motor stops completely, in accordance with the law of conservation.
But instead of stopping, the rotor began to accelerate. Heins recounts that the first time it happened, the magnets starting flying off and hitting the walls, as he ducked for cover.
The magnetic friction wasn't repelling the magnets and wire coil. Instead, as Heins explains, the steel rotor and driveshaft had conducted the magnetic resistance away from the coil and back into the electric motor. In effect, the Back EMF was boosting the magnetic fields used by the motor to generate electrical energy and cause acceleration.
He also says it's *NOT* a perpetual motion machine. He's asking experts to explain him why that happened, and if it could turn into a way to make electrical generators more efficient. -

Re:Renewable not!
According to this article from April, they'd need much more area for the solar energy, or wind energy, than for the CO2 harvesting.
As for "relatively complex molecular structures", I've researched some sorbents, and one is a solution of NaOH, sodium hydroxide, or "lye". It happens that it is produced by the electrolysis of seawater, which also produces...hydrogen. -
Re:ah!
OTOH, it will generate 30TB per day.
According to http://www.lsst.org/About/Tour/software.shtml
"Current projects show that approximately 5000 mathematical operations are required per pixel of the image to process and classify survey data. Scaling this to the size of the LSST data stream shows that approximately a thousand of today's high-end processors will be required a feasible proposition. Advances in processor power over the next five years will reduce this number to a few hundred, by which time the required LSST computer system will seem quite pedestrian. Storing this data is also well within even today's technology. At current prices, a one-petabyte disk storage system costs less than $1 million; in five years this price should drop to well below $100,000. Keeping all of the LSST data online will certainly be affordable."
Windows may not play a central data reduction role, unless Microsoft can support 100 CPUs within the next six years. Of course six calendar years is a long time in techo-years. By then, perhaps the data analysis would be done on game consoles.

We already have this?
If we're talking about publicly-ranked search results, the results may expose more than we're comfortable with.
Wikipedia content is either right or wrong. It's not meant to be subjective, hence it can be patrolled and corrected. Now they want to apply it to subjective content; I don't see that making sense, albeit at first glance. User A is a technocrat who loves Monty Python. Hardly an isolated case. Use B is a 15yr old who likes whatever he/she likes this week. There's no "patrolling" this, except to address systematic abuse.
The concept is fine for slashdot, or any "closed" system, where the users generally share a common set of expectations. At /., I find all +5 content to be generally insightful, interesting, funny, etc. At least it seems so to me. Either I'm new here, or we've all seen Life of Brian. Whether that's utopia or not is another question altogether.
Expand this out to the general internet user, and the result will, of course, reflect the general focus of human society. That will be interesting, to say the least, though I'll bet $5 that anything entertainment- and religion-based will always be at the top of the results. Is that what people want? Ipso facto perhaps, but sure as hell not I.
Let's keep in mind that (no offence to anyone specific) ~80% of Americans believe in God, less than 50% subscribe to Darwin, ~30% believe in "UFOs, witches and astrology" (if you can believe this poll that is). Of course, smart people believe weird things too.
Add to this, that 81% of those who have seen two or more "Police Academy" movies believe that O.J. is innocent, and you have a recipe for disaster. -

Re:What about the Phoenix?
Here is a nice article:
http://www.physorg.com/news6341.html
Here is a quote:
""Where is the sexy new stuff?" they ask. "For that matter, where is the sexy old stuff? Why isn't Mike Griffin pulling out the blueprints for X-30/NASP, DC-X/Delta Clipper, or X-33/VentureStar? Billions of dollars were spent on these programs before they were cancelled. Why aren't we using all that research to design a cheap, reusable, Single-Stage-To-Orbit vehicle that operates just like an airplane and doesn't fall in the ocean after one flight?"
The answer to this question is: All of these vehicles were fantasy projects. They violated basic laws of physics and engineering. They were impossible with current technology, or any technology we can afford to develop on the timescale and budgets available to NASA. They were doomed attempts to avoid the Cold Equations of Spaceflight. "
He goes on to explain why SSTOs won't work and so on. I found Dr. Bells articles depressing and insightful. In the end I would rather settle for something that works rather than some space cadets wet dream that hasn't a chance of taking off.
Well and then there is the first project Orion which would have to suffer from not-on-my-planet syndrome but it might have worked. -

This is going to expode in the next few years
I'm currently taking a nanophysics module as part of my physics degree, and we have been required to read a UK government report on the development of nanotechnology, and there is plenty in there to worry me even as an unqualified scientist.
Public awareness of nanotechnology is low. 29% of Britons (who, no offense, are likely to be more informed than Americans) have heard of the term and only 19% could offer a definition. Of those who knew what it was, 68% thought it would improve life whilst 4% thought it would make life worse
I've read stuff in this report though, that if it were widely known could well cause widespread panic, and leave nanotechnology about as trusted as GM crops. Nanoparticles, by virtue of their vastly increased surface area and the beginnings of quantum effects, can have very different properties than their bulk material counterparts. Bulk copper, for example, is soft and malleable. Copper particles less than 50nm or so across are very hard crystals.
Toxicity can change too - http://www.physorg.com/news63466994.html - there are some indications that substances which are benign in bulk are dangerous as nanoparticles. Of course, nobody knows because the people using these nanoparticles in products like suncreen haven't bothered to test them properly. They haven't bothered because its expensive, and the legislation hasn't caught up with the technology yet. Bulk and nanoparticles are for the most part treated as identical.
When the oh so trusting public I mentioned before find out about this, and find out that the people who knew about it didn't do enough to inform them, and the people using these substances in products didn't bother to do any real testing on them, they are going to be really pissed off. People will tolerate greedy corporations, corrupt politicians and idiotic media - but they have been known to get off their arses and complain when they discover they could've been rubbing carcinogens on their children's skin.

Re:Why supercomputers?You remember when that North Carolina State professor made a supercomputer out of eight PS3s? He couldn't have done that if "supercomputer" didn't have a rock solid meaning. Which would be what exactly? Here is a little quote about the eight PS3 supercomputer from here: "Scientific computing is just number crunching, which the PS3s are very good at given the Cell processor and deploying them in a cluster," Mueller says. "Right now one limitation is the 512 megabyte RAM memory constraint, but it might be possible to retrofit more RAM. We just haven't cracked the case and explored that option yet." Another problem lies in limited speed for double-precision calculations required by scientific applications, but announcements for the next-generation Cell processor address this issue.
"In the computing world there is a list of the top 500 fastest computers," Mueller says. Currently the fastest is BlueGene/L, a supercomputer with more than 130,000 processors at Lawrence Livermore National Laboratory. The PS3 cluster at NC State does not break into the top 500, but Mueller estimates that with approximately 10,000 PS3 machines anyone could create the fastest computer in the world - albeit with limited single-precision capabilities and networking constraints. It's a sweet thing, no doubt, but still with limited memory, limited FP, limited bandwidth, unlimited price. -
how high a stack of PS3s
~10000 would be a good guess.
Quote: "Mueller, an associate professor of computer science, has built a supercomputing cluster capable of both high-performance computing and running the latest in computer gaming. His cluster of eight PS3 machines - the first such academic cluster in the world - packs the power of a small supercomputer, but at a total cost of about $5,000, it costs less than some desktop computers that have only a fraction of the computing power.
...

Finally, saying that we should turn off coal plants is obviously a joke. You know that will never happen. But what is happening is where coal plants were planned, those are being stopped. For example, Texas power had plans for MAJOR coal plant expansions. They were going to quadruple their plants, and it was going to be all coal. But they were bought by new yorkers who has stopped that. Now, they are expanding with alternative and they are on the fast track for a nuke (and I believe that they are looking at doing a buynch of nukes). -

Re:Also the Fear of Where the Money Comes From
First thing - using a mirror film to concentrate the light onto each single PVC allows for very lightweight high efficiency solar power conversion, about 40%. Since the light in space is more intense that that which reaches earth filtered by miles of atmosphere, and the 100+:1 ratio, that 150 acres will be well under 1 actual acre of PVCs. That's still a lot of PVCs, but far less than you were thinking.
The Shuttle cannot get anywhere near geosynchronous orbit. They'd be far far better off using a new Delta IV rocket.
But then, you're assuming that they're going to be sending up PVCs.... Why not just the mirror framework and send a nice 5-10MW down as... sunlight? Not only could it be a nice power source, but also a really nice weapon, just turn up your enemies to "sunny side up". -

Re:13% is considered "high efficiency" now?With 3.4 billion years of evolution behind photosynthesis, plants have managed to do a bit better than that. According to this wiki plants are very efficient:
http://www.physorg.com/news95605211.htmlFleming is the Deputy Director of Berkeley Lab, a professor of chemistry at UC Berkeley, and an internationally acclaimed leader in spectroscopic studies of the photosynthetic process. In a paper entitled, Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems, he and his collaborators report the detection of quantum beating signals, coherent electronic oscillations in both donor and acceptor molecules, generated by light-induced energy excitations, like the ripples formed when stones are tossed into a pond.
Electronic spectroscopy measurements made on a femtosecond (millionths of a billionth of a second) time-scale showed these oscillations meeting and interfering constructively, forming wavelike motions of energy (superposition states) that can explore all potential energy pathways simultaneously and reversibly, meaning they can retreat from wrong pathways with no penalty. This finding contradicts the classical description of the photosynthetic energy transfer process as one in which excitation energy hops from light-capturing pigment molecules to reaction center molecules step-by-step down the molecular energy ladder.
"The classical hopping description of the energy transfer process is both inadequate and inaccurate," said Fleming. "It gives the wrong picture of how the process actually works, and misses a crucial aspect of the reason for the wonderful efficiency."
You've got to admire the subtlety of evolved systems. -

Nature Article"If you look closely right around 34 seconds you can see what looks like the other set of jaws chewing." I don't believe that is what you are seeing.
From the original source of information and in the Journal Nature's News, these jaws are definitely not for chewing. If you look at the images of x-rays you will see that these are more 'hooks' or teeth than jaws.
In the rest of the articles, they talk about this mearly being the method by which the eel pulls the food down or holds on to it. I don't believe any fish (or snakes for that matter) really 'chew' their food.
I think what you are seeing in that video is the extra skin around the inner part of the mouth billow out as the animal attempts to suck the food in (which as mentioned, most fish do). I don't know a lot about eels so I can't verify that the eel in that video is a moray eel much less one of the kinds that have that kind of device to ingest food. There's over 200 species of moray eels so I guess it would be futile to try and verify it. Still an interesting video but I predict you would see that kind of action when any fish feeds. -
Re:Focus length?
If scientists can construct a neural network that can simulate the infra-red vision of snake, then doing the same with the display of a LCD shouldn't be that difficult.

... And lastly, I want you to know exactly how close the manufacturing of that very first CD came to killing -- and I mean killing deader than Elvis -- the entire music industry. Maybe ABBA's "The Visitors" was the first commercially released CD in the United States but even Wikipedia says there were 16 different discs released in Japan first, it wasn't until a year later they came to the United states and all sixteen of them couldn't be ABBA. Furthermore they were popular at the time, how could that kill the music industry? There was only trash on Blu-Ray for a while but that doesn't mean other movies aren't going to come out. Ugh, I hate articles that are written poorly & contain pointless interjections making fun of my age. Of all the news sources you could link to, this one is pure trash.
He also forgot the part where they re-released a few new or live tracks on a disc just to make the die hard fans buy into another medium. That kind of practice really makes me sick. Of course, we're doomed to see it repeated until the end of time in the name of making another buck. -
Re:Not just lithography
"This isn't really that new. . . "
The article is extremely short on details, but it sounds very similar to what IBM has done in the area of "statistical timing" over the last couple of years.

Re:Triclosan is used to prevent skin fungal infect
Physorg.org, an organization that apparently exercises little oversight over the articles it runs.
Got any references to back this up?
This is an article on PhysOrg about alien spacecraft parts being found that was referenced in the comments of a recent Slashdot story. In the comments below the article a PhysOrg editor explains "As scientists, we truly believe that even some irrational theories have the right to be announced" and "It's up to the readers to trust the facts or not and to form his/her own opinion. Our mission is to deliver science news content released by official institutions". I'm not saying that there is no merit to any particular article on the site, but the original poster's description as "an organization that apparently exercises little oversight over the articles it runs" seems fairly apt. -
Re:lolGuess you didn't get the memo:
Poker is a special challenge for computers -- which can already consistently beat humans at chess, checkers and backgammon -- because the gambling game includes deliberate deception, unpredictable emotions of opponents and elements of chance as well as mathematics.

origin of comets still unknown. my crackpot theoryWe still don't know where comets but I suspect life was formed where they came from before they became comets and not in the comets themselves.
If you have have been reading science stories lately.
It might be life Jim..., physicists discover inorganic dust with life-like qualities
http://www.physorg.com/news105869123.html
The article states: Particles in a plasma can undergo self-organization, This effect results in microscopic strands of solid particles that twist into helical structures. Under the right conditions, particles of inorganic dust can become organized into helical structures. These structures can then interact with each other in ways that are usually associated with organic compounds and life itself.
I have a theory that has been called crackpot by many of my friends,
Maybe it's nutty, but I am putting it here in the event that someday if it's proven correct maybe I will get a little credit.
Let me add a few minor crackpot theory alterations, maybe it's possible for high temperature plasma based DNA, life to slowly adapt to cooler non-plasma organic life?
Possibly how life was formed. (my crackpot theory) Dec 30, 20061. All higher elements such as carbon an Oxygen had to be formed in the core of a star. These could only have been released in a super Nova.
2. Our planet, sun and solar system much have been formed from the remains of such a super Nova.
3. Within a star must be strata of gases, liquids and light solids like rocky material and heavy iron solids. These were created in the nuclear reactions and precipitate down withing the star and eventually settle into there own strata.
( I have since been told only plasma can exist, but I am not completely convinced. Either way there would still be strata, and now we learned that inorganic DNA like molecules can form within plasma )
4. All objects such as comets and asteroids must be composed of super nova debris. I would think each of the three types of objects comets *water" and smaller "water" asteroids are from similar strata while stony asteroids are from silicon rich layers and then heavy ones from Iron rich layers.
5. With in a star, nothing is really solid at such fantastic temperatures and pressure but everything must seem like a super heated ocean environment.
6. Like in the oceans we have solid methane gas that only stays solid because of the pressure. And we also have super heated water that stays liquid at +700C, and supports life at these temperatures.
7. Below the earth crust is far more life then at the surface, these are all extreme-o-files living off of other chemical processes such as sulfur reactions. These single celled organisms also live in very high temperatures and pressures.
8. Comets are full of amino acids. How did they get there? They must have been formed within the star itself?
9 The chemistry of a Red giant star and regular stars must contain oceans of liquid Hydrogen, methane and water at different strata. All at somewhere near 4000C (measured within a sunspot) possibly lower and at enormous pressure.
10. For the most part much of the chemistry at 0 to 50 C on at 1 atmosphere of pressure can work at much higher temperatures when under higher pressure.
11. The Volume of high temperature oceans within a sun are much much larger then can be found on any planet.
12. With increased volume this increases the probability of interesting rare chemistry occurring such as the type that created DNA. Also the stability over a very like time, 5 Billion years, would allow such reactions to occur and evolve.
13. The creation of DNA / and it's protein molecular engine, the single celled organism) is the only think I find incredible to have evolved on earth. That engine It's the most complex thing on this planet.
14 Like on earth appeared almost immediately after the surface cooled. This seems like life was trapped in
