Source or Sink can depend on usage of the land
An article from earlier in the year attests to how land use can affect if it will act as a sink or source. http://www.physorg.com/news3857.html
Another article from the same site shows how studies of the Amazon river basin reveal that carbon emissions from the Amazon river are younger than previous thought http://www.physorg.com/news5471.html
Really what comes about from these articles and others is that we still don't have a complete picture. While it is great press to claim we can simulate the earth and predict things like global warming and cooling we still run into the fact we don't know all the variables. Yes man contributes but how much? Indirect methods are revealed by how land use affected CO2 emissions and absorption.
I do think that what the Earth is doing on its own in regards to CO2 emissions should not be weighed against how well we reduce our own emissions. Granted the changes in the planet may seemingly undo what we accomplish we still improve our ecosystem by reducing OUR effect on it. -

Re:Won't someone please think of the snowmen!If the polar ice and the water around it had the same amount of salt, then you would be correct: the ice melting would not impact the ocean level.
However, when taking the different salinity into account, things change. As you know from Archimedes, the ice is displacing exactly enough water to offset its weight (that is, the displaced water weighs as much as the ice). The thing is, it takes less *saltwater* to do that than it would *freshwater*. So when the freshwater in the ice melts, the levels rise.
If you don't believe me, check this article, it includes a picture from an experiment.

Re:Luddites
The belief in AGW rests on two pillars: Historic Temperature reconstruction and computer models of climate(even these two things are not independent of each other...many of the latter are baselined by the former). Temperarture reconstruction are mainly done through proxies(tree rings, ice cores...etc). They rely on heavily on statistical tools to merge all avaiable data and pretty much does an extropolation on extrapolated data. How accurate can this be? Not sure since there hasn't been any fund to see if proxies match up with recent instrumental data Link.
As for the computer models...water vapor is considered the primary AGW gas by far and we cannot even come close to properly modelling it. So how accurate can these models be? -

3-D chips do decreases wire length, according to the thesis and the IEEE paper in the links below, 56% less interconnect is required for a 5 layer chip. Wafer bonding has been thoroughly investigated, and processes compatible with standard CMOS have been found and will soon find a use in memory (I'm sure I read something about a start-up stacking chips for memory, I think it was called Tezzaron).
http://www-mtl.mit.edu/researchgroups/icsystems/3d csg/publications.html
http://www.stanford.edu/class/ee311/NOTES/3DProc_I EEE.pdf
The big problems facing the industry are the lack of good design tools and the issues associated with yield and heat. Design tools will be developed as the processes become more refined. Yield issues and heat will likely need to be taken into consideration in the design. Consider if you have an 80% yield on each wafer; when you have 5 layers of silicon--assuming defects are not correlated to the location on the chip, and no defects due to the bonding process--your yield reduces to 33%. Of course, we are able to have more redundancy with more silicon layers, so we can design systems that are fault tolerant (google: fault tolerant architectures. lots of good stuff). The costs of the chips will probably direct represent the decrease in yield -- good designs and tools will likely save companies a lot of money (i shouldn't give away my secrets before i patent them :-)
Cooling the higher density chips is probably the most major hurdle towards development of 3-D circuits. A few of these documents hint that microfluidic cooling systems may be the solution. Georgia Tech researchers made an advance on this end a few weeks ago by presenting a microfluidic manufacturing process compatible with standard CMOS design:
http://www.physorg.com/news4657.html
Expect lots of great things in the years to come. For now you can probably expect 3-D integration to creep into specialty mixed signal chips that are extremely expensive, and memory where heat generation is less of a problem. Microfluidic cooling technologies will be adopted in the near term for 2-D high power chips. The first 3-D micro-processor architectures will probably use extra layers for clock distribution, global interconnect systems, and power distribution systems. Caching systems will likely be added to as a third layer until new design approaches (and better tools) allow for the design of multi-layer integration with logic interspersed between the layers. -

Re:weirdos"My point is that is that if you identify with the Columbine killers, it's because you're a homicidal maniac"
Again you miss the point, I can only wonder sometimes at this culture. We are disconnected from nature to such a degree that we think killing in general is a bad thing. I am not talking Human killing, I am talking killing anything even a fly or ant. We as a culture in general meaning Western Judeo-Christian has come to the insane conclusion that killing is so wrong even the thought is sinful. Now devoid of understanding of the warning signs that other animals in nature display we blunder into these problems. Rattlesnakes have their rattles, telling you - HEY, back off or I will strike, Cats arch their back, pull back their ears and hiss. If you reach for a Cat in such a state your get a nice deep scratch or bite. And being a utter idiot you damn well deserved it.
I can only surmise that the shooters at Columbine had been doing the human equivalent of arching their back and it had been ignored.
a homicidal maniac is bad terminology. I was working concert security when a Friend of mine who wasn't working security hit one of the security crew (also a friend). The guy was 6'6" and really drunk. He proceeded to threaten other staff with a knife. If a cop had seen this, he would have tazered or shot him. I merely yelled at him to put the damn knife away and cool down. Which he did.
For whatever reason, he was showing signs of the 'Don't come near me, I am dangerous now' I have learned to understand the signs of violence. I have also come to see that most people are actually trained to be ignorant of what's happening around them. You cannot push people into corners and then ignore them until they try and step out of the corner. In Japan they have a saying "The nail that sticks out, gets hammered down.". But Humans are not nails. Humans are predators, and if you ask a biologist, we as a species, are technically Super Predators. Mr Hyde lurks under the surface of each one of us. In Sin City, Mickey Rourke played Marv, one comment from a narrator was 'In another time he would have been a great general or hero' (I'm pulling from memory). In this world he was a misfit.
You paint with too broad a brush and in the wrong colors.

Has this guy EVER researched nanotech?
I don't know why the article referred "nanotech" as nanomachines or molecular assembly. To quote: "Drexler says nanotechnology alone will smash the barriers Huebner foresees, never mind other branches of technology. It's only a matter of time, he says, before nanoengineers will surpass what cells do, making possible atom-by-atom desktop manufacturing."
Pfft... talk about uninformed people. Better go to http://news.nanoapex.com/ and get REAL information. (Yeah I know, Drexler is the father of nanotech - but Drexler's nanotech is NOT the nanotech that countries are investing billions in R&D. Too bad for him, tho)
Nanotechnology isn't just about molecular-level manufacturing. It's about nanoelectronics, nanomaterials for energy storage, new diagnostic machines with nanoscopic precision, analysis of biology in the nanoscale (a completely UNEXPLORED field so far), new materials for permanent artificial bones, filters which will separate the salt (and microorganisms) from seawater at the molecular level... and of course, your 6-million-dollars bionic eyes. Yes. All of this is possible.
Now, Want a real-world example of technology innovation?
Vehicle with the highest fuel efficiency sets new world record . "PAC-Car has now achieved its goal: it finished the course at the Shell Eco-Marathon taking place on the Michelin test track at Ladoux, France, using only 1.07 grams of hydrogen."
Hey, if that's not innovation, I don't know what it is.
Now think of the advancements in say, molecular engineering (chemistry) that will be possible by the time we start comparing home computers by their teraflops.
So, innovation getting slower? Yeah, right. -
Re:me too me too!
How about if his competitor has 80% of the market and threatens major supliers if they use the competitors products?
Intel apply things like retroactive incentives (ie we'll give you money back later if you have been good). From one article where they nailed HP: "When AMD succeeded in getting on the HP retail roadmap for mobile computers, and its products sold well, Intel responded by withholding HP's fourth quarter 2004 rebate check and refusing to waive HP's failure to achieve its targeted rebate goal; it allowed HP to make up the shortfall in succeeding quarters by promising Intel at least 90% of HP's mainstream retail business."
Also, the Clayton Antitrust Act includes "sales on the condition that the buyer not deal with the seller's competitors. (Section 3)". AMD can quite easily claim that Intel is enforcing vendor lock-in, another major part of anti-trust law.

does samsung have a new technology for flash chips?
Could be. According to this Samsung is using the NAND they first developed back in 1989. Performance is better than normal drives,
The SSD's performance rate exceeds that of a comparably sized HDD by more than 150 percent. The storage disk reads data at 57 MegaBytes per second (MBps) and writes it at 32MBps.
Sounds great to me. My laptops only have 6 gigs of storage right now. I'm sure they give me 5MB/s or less. Samsung's device then would be bigger, have better speed, lower power consumption, noise and heat from one without losing anything. As is, I expect my laptop's drives to die due to mechanical abuse so I sync the contents via sftp frequently and make CD backups two or three times a year. If cheap enough, flash memory would be great to have as a hard drive. Sooner or later, they will be cheaper because moving parts are expensive.
Because most computers use legacy software with file systems that are not suited to flash, Samsung will have make their drives smart enough to avoid burning out.

Re:QuestionLike any scientific endeavor, the journey is as important as the final goal. Many new techniques and ideas come along to put the whole picture together. So even if a practical realization of this technique may not be feasible, the learning (from the experiments and theory) will be useful.
PhysOrg (Article on Caltech's work on weighing molecules) has comment about the possible applications:
The new method might ultimately permit the creation of microchips, each possessing arrays of miniature mass spectrometers, which are devices for identifying molecules based on their weight. Today, high-throughput proteomics searches are often done at facilities possessing arrays of conventional mass spectrometers that fill an entire laboratory and can cost upwards of a million dollars each, Roukes adds. By contrast, future nanodevice-based systems should cost a small fraction of today's technology, and an entire massively-parallel nanodevice system will probably ultimately fit on a desktop.

MS jokes and animosity aside...
I've been waiting for MS to merge the Pocket PC and Smartphone versions of Windows Mobile for a while. Having used Dell's Axim x50v, I have to say that it is a great (and relatively inexpensive) PDA. It is very fast, has a large screen and offers many expansion choices. Also, it runs a ton of WinCE apps. One major drawback - it lasts only a fraction of time compared to an average cell phone. However, if "Magneto" (ok, the name is cheesy) were to add a "hibernate" funtion which wakes PDA up on incoming phone call, that would really make battery last *much* longer (so you don't need to keep it on to receive calls). I think that MS is in a good strategic position to take on RIM because it recently became the #1 PDA OS shipped. http://www.physorg.com/news4003.html

Re:What if Dark Energy Wasn't Required
That's the summary of the story that's been put together so far
:)The redshift they describe is 'cosmological redshift'. It is true that it would be technically incorrect to call it a Doppler redshift if the currently-held accelerating universe view is actually true.
There are Doppler redshifts on top of this as well - rotations and movement add to or subtract from the cosmological redshift.
What the papers I quote have been finding is that cosmological redshift (whether Doppler or not) isn't enough.
Intrinsic redshifts are statistically important. They do not, however, get rid of the cosmological component.
The current 'accepted' value of the Hubble Constant, which reflects the age of the universe, is 72 km/s/Mpc, giving us an age of about 13 billion years.
Taking the instrinic redshift from that gives us a Hubble Constant of 50-60 km/s/Mpc, which gives us an age of about 18 billion years, so that theorists might have time to deal with the 'vegetable soup' phenomenon, to quote a sound bite.
(Looking back to 1-2 billion years after the Big Bang, the universe still doesn't look very young. Of course, the revised age will also alter back the ages of some of the objects.)
There's some reason to believe that even the remaining cosmological component may not actually represent expansion, and it was presented in one of Edwin Hubble's later lectures, "The Observational Approach to Cosmology".
The premise, basically, is that a redshift would give a corresponding decrease in photon density, if due to expansion, but it doesn't.
We'll see what happens over the next few years, though
:)Thanks for the link!

Re:Uh, what???
"These stars are not the most massive known," noted Levesque. "They are only 25 times the mass of the sun, while the most massive stars may have as much material as 150 suns. Nor are they the most luminous, as they are only about 300,000 times the luminosity of the sun, not the factor of 5 million or so attributed to the most luminous stars. They aren't even the coldest stars known - brown dwarfs have such low temperatures that they can't even fuse hydrogen. But the combination of modestly high luminosities and relatively low temperatures DOES mean that they are the biggest stars known, in terms of their stellar diameters."

Links to better articles
As seems to be increasingly the case, I already submitted (rejected) variants of this story twice over the past week. I've pasted one of those variants below, which has links to sources far more information than the freakin' Guardian:
Greenhouse gases could breathe life into Mars
MSNBC, New Scientist and PhysOrg report on research by Margarita Marinova and others on using synthetic greenhouse gases to warm the Martian atmosphere and create the conditions for life to thrive. The study focused on fluorine-based gases (dubbed "super-greenhouse gases"), which would be non-toxic, nearly 10,000 times as effective at capturing heat as CO2, and could be made from Martian resources. The research concluded that adding 300 parts per million of these gases would lead to a feedback effect by unfreezing CO2 and water on the surface. According to Marinova, 'Since warming Mars effectively reverts it to its past, more habitable state, this would give any possibly dormant life on Mars the chance to be revived and develop further.' The feasibility and consequences of such terraforming have been debated in the past.
Also, note that contrary to the accepted submission's title, NASA hasn't done any sort of proposal of actually doing this. This is simply cool research exploring a very interesting "What-if". -

"Cell Processor Unveiled" form physOrg
Cell Processor-Based Workstation Prototype
The companies expect that a one rack Cell processor-based workstation will reach a performance of 16 teraflops or trillions of floating point calculations per second.
Cell Processor Unveiled
IBM, Sony Corporation, and Toshiba Corporation today unveiled for the first time some of the key concepts of the highly-anticipated advanced microprocessor, code-named Cell, they are jointly developing for next-generation computing applications, as well as digital consumer electronics.
Specifically, the companies confirmed that Cell is a multicore chip comprising a 64-bit Power processor core and multiple synergistic processor cores capable of massive floating point processing. Cell is optimized for compute-intensive workloads and broadband rich media applications, including computer entertainment, movies and other forms of digital content.
Other highlights of the Cell processor design include: -- Multi-thread, multicore architecture. -- Supports multiple operating systems at the same time. -- Substantial bus bandwidth to/from main memory, as well as companion chips. -- Flexible on-chip I/O (input/output) interface. -- Real-time resource management system for real-time applications. -- On-chip hardware in support of security system for intellectual property protection. -- Implemented in 90 nanometer (nm) silicon-on-insulator (SOI) technology. Additionally, Cell uses custom circuit design to increase overall performance, while supporting precise processor clock control to enable power savings.
IBM, Sony Group and Toshiba will disclose more details about Cell in four technical papers scheduled for presentation at the International Solid State Circuits Conference. "Less than four years ago, we embarked on an ambitious collaborative effort with Sony Group and Toshiba to create a highly-integrated microprocessor designed to overcome imminent transistor scaling, power and performance limitations in conventional technologies," said Dr. John E. Kelly III, senior vice president, IBM. "Today, we're revealing just a sampling of what we believe makes the innovative Cell processor a premiere open platform for next-generation computing and entertainment products." "Massive and rich content, like multi-channel HD broadcasting programs as well as mega-pixel digital still/movie images captured by high-resolution CCD/CMOS imagers, require huge amount of media processing in real-time. In the future, all forms of digital content will be converged and fused onto the broadband network, and will start to explode," said Ken Kutaragi, executive deputy president and COO, Sony Corporation, and president and Group CEO, Sony Computer Entertainment Inc. "To access and/or browse sea of content freely in real-time, more sophisticated GUI within the 3D world will become the 'key' in the future. Current PC architecture is nearing its limits, in both processing power and bus bandwidth, for handling such rich applications." "The progressive breakdown of barriers between personal computers and digital consumer electronics requires dramatic enhancements in the capabilities and performance of consumer electronics. The Cell processor meets these requirements with a multi-processor architecture/design and a structure able to support high-level media processing. Development of this unsurpassed, high-performance processor is well under way, carried forward by dedicated teamwork and state-of-the-art expertise from Toshiba, Sony Group and IBM," said Mr. Masashi Muromachi, Corporate Vice President of Toshiba Corporation and President & CEO of Toshiba's Semiconductor Company.

Re:What is the Speed of Sound?The space shuttle isn't designed to fly like an airplane, it (like other rockets) are designed to get you into space. If you'll read a little more of the article:
The accomplishment will be included in the 2006 Guinness World Records book, set for release this time next year, as follows:
An airplane that goes Mach 10 will be an amazing achievement for an air-breathing engine (a.k.a. non-rocket) aircraft.
"On 27 March 2004, NASA's unmanned Hyper-X (X-43A) airplane reached Mach 6.83, almost seven times the speed of sound. The X-43A was boosted to an altitude of 29,000 m (95,000 ft) by a Pegasus rocket launched from beneath a B52-B aircraft. The revolutionary 'scramjet' aircraft then burned its engine for around 11 seconds during flight over the Pacific Ocean."
...
The X-43A flight easily set a world speed record for an air-breathing engine aircraft. The previous known record was held by a ramjet-powered missile, which achieved slightly more than Mach 5. A ramjet operates by subsonic combustion of fuel in a stream of air compressed by the forward speed of the aircraft itself, as opposed to a normal jet engine, in which the compressor section (the fan blades) compresses the air. A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the whole engine remains supersonic.
The highest speed attained by a rocket-powered airplane, NASA's X-15 aircraft, was Mach 6.7. The fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71.
