The US National Institutes of Health invests $28bn annually in research. European spending is lower, although the European Union is closing the gap, helped by a shortsighted American policy of &quot;flatlining&quot; many scientific research budgets. (Perhaps this is because scientists have an annoying tendency to discuss things that conflict with the Bush administration&#39;s view of reality, such as global warming, evolution, the insufficiency of the New Orleans levee system and the medical potential of stem cells.)

Some tech groups are beginning to worry that major IT industry priorities, including patent reform, may lose out to other priorities in the U.S. Congress this year.In the last couple of weeks, large tech companies have renewed their push for patent reform legislation in the U.S. Congress, despite opposition from U.S. President George Bush&#39;s administration and some labor unions.The Computing Technology Industry Association (CompTIA) is concerned that a congressional debate over an economic stimulus package, plus typical election-year gridlock, could hurt the prospects for patent reform and other tech priorities, said Michael Wendy, a spokesman for the trade group.The House of Representatives&#39; economic stimulus package includes tax write-offs for small business purchase of equipment, which could include computers, Wendy said. That&#39;s a good move, but patent reform, a research and development tax credit, H-1B visa reform, and other issues remain undone, he said.&quot;We hope that Congress -- assuming they pass an [economic stimulus] package -- doesn&#39;t just say, &#39;Well, we gave you some favorable tax provisions that will help boost industry activity and have a long-tail effect on the economy, so that should be enough for you guys this session,&#39;&quot; Wendy said last week. &quot;One thing we&#39;re concerned about is that the economic stimulus bill may be seen by Congress as a &#39;get out of jail free&#39; card when it comes to other of our tech policy agenda.&quot;The House in September passed a patent reform bill -- supported by many large tech vendors, but&#160;opposed by several small tech companies&#160;-- but similar legislation has been stalled in the Senate. Large tech vendors, including Microsoft, IBM, and Symantec, have&#160;called for patent reform, saying it&#39;s too easy for companies with no intention of creating products to buy up patents and file multimillion-dollar infringement lawsuits against other companies.On Jan. 22, Senate Majority Leader Harry Reid, a Nevada Democrat, said patent reform was a priority, but it was in a line behind several other bills, including an economic stimulus package and a government surveillance authorization bill. The Senate would turn to patent reform, &quot;time permitting,&quot; he said then.&quot;On patent reform, we must carefully strike the right balance with a bill that promotes rather than blocks innovation from enterprising entrepreneurs,&quot; Reid added.The Senate Judiciary Committee approved its version of the Patent Reform Act on Jan. 24, and the bill is awaiting action in the full Senate.But earlier this week, the U.S. Department of Commerce sent a letter to the Senate Judiciary Committee raising concerns about the bill. The letter, outlining the Bush administration&#39;s views, focused on a section of the bill that would apportion infringement damages in a new way. Currently, courts generally consider the value of the entire product when a small piece of the product infringes a patent; the bill would allow courts to base damages only on the value of the infringing piece.The wide-ranging bill would also allow a new way to challenge patents after they are issued.That provision would &quot;create more problems than it solves,&quot; said the Commerce Department letter, signed by Nathaniel Wienecke, the agency&#39;s assistant secretary for legislative and intergovernmental affairs. &quot;The administration believes that such a dramatic change from current jurisprudence may have the unintended consequence of reducing the rewards of innovation and encouraging patent infringement,&quot; Wienecke wrote.Both sides can still work out their differences, Wienecke added.In addition, 14 labor unions, including the United Steelworkers, the Patent Office Professional Association and the Communications Workers of America, sent a letter to Senators Wednesday, saying they were concerned about the patent bill. &quot;Key parts of the proposed legislation may have the effect of increasing the likelihood of American inventions being stolen by our international competitors and, consequently, inhibiting sorely needed new investment in domestic manufacturing,&quot; the letter said.Still, some representatives of the tech industry say they&#39;re hopeful that patent reform can move forward.Senators, representatives of the Bush administration and other interested parties have been meeting regularly &quot;to find balanced solutions on all the issues,&quot; said Mark Isakowitz, spokesman for the Coalition for Patent Fairness, a group representing several large tech companies. &quot;We respectfully disagree [with the Bush administration] on damages, but we are confident ... we can work through concerns and achieve broad consensus on the bill, which would be a victory for the administration, the Congress and our economy,&quot; he added.

In anticipation of Moore&#39;s Law becoming irrelevant in the next 10 to 20 years, the National Science Foundation (NSF) wants funding for research that could lead to a replacement for current silicon technology.The NSF last week requested $20 million from the U.S. government for fiscal 2009 to start the &quot;Science and Engineering Beyond Moore&#39;s Law&quot; effort, which would fund academic research on technologies, including carbon nanotubes, quantum computing, and massively multicore computers, that could improve and replace current transistor technology.Moore&#39;s Law states that the number of transistors that can be placed on silicon, and its attendant computational capability, doubles every 18 months.Human and economic progress in the U.S. over the past 20 years has depended on an increasing ability to do information processing and computing, said Michael Foster, division director of computing and communication foundations at NSF. &quot;If the current technological basis of that ends, we&#39;ve got to find some way to replace it, or we&#39;re going to stop moving forward.&quot;The traditional way to improve transistor performance is to decrease the thickness of the gate oxide, or insulator that separates one part of the transistor from the other. The looming barrier is that transistors will be shrunk as small as possible for them to still work effectively, after which they may need to be replaced or somehow improved on, Foster said.&quot;In the kind-of near future -- in 8 to 10 years -- we will have reduced that gate oxide thickness to the point where it will no longer act as an effective insulator,&quot; Foster said. &quot;I don&#39;t know of any other proposals to increase the performance of... [current] transistors, which is why we have to look at really radically new structures like transistors based on nanostructures.&quot;Carbon nanotubes could provide a way to create smaller transistors, Foster said. Transistor performance is correlated to transistor size -- the smaller a transistor, the better it performs. &quot;Carbon nanotubes give us the possibility of much smaller transistors than we can make right now,&quot; Foster said.Carbon nanotubes could also be used as interconnect on circuits, Foster said. Nanotubes could be placed one after another on a circuit, though it would require fault-tolerant architectures. That would require new research and improvements on chip architecture as well, Foster said. &quot;We think architecture is going to become an important component of any beyond-Moore&#39;s-Law topic,&quot; Foster said.Looking far ahead, quantum computing could be the next answer to delivering massive computing power, Foster said. Quantum computing uses matter -- atoms and molecules -- to process massive amounts of tasks at supercomputing speeds because basic data units, called qubits, hold both the values 0 and 1 simultaneously and share those values among all qubits. It is based on the laws of quantum mechanics, which look at interaction and behavior of matter on atomic and subatomic -- proton, neutron, and electron -- levels.&quot;The implementations we have so far will, for example, trap single ions at very cold temperatures and use those as qubits. That takes a room full of equipment to make a very small register. We clearly need progress there, but it&#39;s promising,&quot; Foster said.The idea behind quantum computing is that it provides inherent parallelism, so its development requires improvements in parallel programming, in which several computers work on the same program together, Foster said. Parallel programming has been researched since the 1970s, but progress has been slow, Foster said.&quot;We could continue to expand our IT abilities without necessarily expanding the capabilities in any one computer. But we need software research to understand how to coordinate the efforts of not just one or two computers, but thousands or millions of computers,&quot; Foster said. That poses a research problem as scientists have been trying to understand parallel programming for decades and haven&#39;t succeeded yet, Foster said.NSF is already doing research in nanotechnology, software, and architectural ideas that will contribute to the effort to develop chips that will continually improve computing power beyond Moore&#39;s Law.Ultimately, current transistors may be hard to replace, Foster said, so researchers may look to develop better architectures and chip designs that use current transistor technology to maintain the computing capability growth rate.&quot;It&#39;s not out of the question to me that we could build very large chips with thousands of cores on them -- I hesitate to go too much higher than that just because it will sound crazy -- but if we did that... we [could] use those things to get done the computing and information technology that we need to have done,&quot; Foster said.The $20 million budget request is modest compared to research budgets of companies like Intel and IBM. &quot;The funding is intended to help laboratories assist, not compete, with research from the private sector,&quot; Foster said. NSF will seed academic laboratories and industry associations like Semiconductor Research to conduct research, which in turn may work with commercial organizations. The commercial organizations may further invest in the research to drive it into mass production, Foster said.Expectations from the project are modest, Foster said. &quot;It&#39;s very early-stage research. Any expectations we have will probably not be accurate.&quot; However, it could lead to better fault-tolerant techniques to design and operate systems with small components in them, Foster said.
