Why Only Three Dimensions?, Science Now
Excerpts: Length, width, and depth: Those three dimensions seem plenty for you and me, but string theorists claim there are at least six others hidden from view. So then why is our world not blatantly 9-dimensional or 1-dimensional or anything other than vivid 3D? New research has shown that of all the possible dimensional realities, only those of three or seven dimensions would survive in an expanding universe. We may have ended up being 3D because it was the most probable.
A Quantum Recipe For Life, Nature
Excerpts: Sixty years on, Erwin Schr?dinger's prediction that quantum mechanics would solve the riddle of how life started has not been fulfilled. But the appeal of using quantum theory to solve the mystery persists.
Innovation Endgame, Nature
Excerpts: The commercial practices of some universities are quietly being transformed by an international chess grandmaster, (...).
Winning move: a company founded by David Norwood (right) is bolstering technology transfer at British universities.
(...) His company IP2IPO has struck deals with British universities that want help in getting their spin-off companies up and running.
In the United States, some academics meet venture capitalists every other day. That's not the case in Britain, however, and university technology-transfer offices face a hard slog in trying to raise funds to back new spin-off companies.
The "Robust Yet Fragile" Nature of the Internet, PNAS
Abstract: The search for unifying properties of complex networks is popular, challenging, and important. For modeling approaches that focus on robustness and fragility as unifying concepts, the Internet is an especially attractive case study, mainly because its applications are ubiquitous and pervasive, and widely available expositions exist at every level of detail. Nevertheless, alternative approaches to modeling the Internet often make extremely different assumptions and derive opposite conclusions about fundamental properties of one and the same system. Fortunately, a detailed understanding of Internet technology combined with a unique ability to measure the network means that these differences can be understood thoroughly and resolved unambiguously. This article aims to make recent results of this process accessible beyond Internet specialists to the broader scientific community and to clarify several sources of basic methodological differences that are relevant beyond either the Internet or the two specific approaches focused on here (i.e., scale-free networks and highly optimized tolerance networks).

Excerpts: Global competition is driving manufacturing companies to change the way they do business. New kinds of shop floor control systems need to be implemented for these companies to respond quickly to changing shop floor environments and customer demands. This paper presents a new concept called iShopFloor-an intelligent shop floor based on the Internet, web, and agent technologies. It focuses on the implementation of distributed intelligence in the manufacturing shop floor. The proposed approach provides the framework for components of a complex control system to work together as a whole rather than as a disjoint set. (...)

All Human Life Is Indexed On The Web - Search Engines Are Changing The Face Of Business Forever, The Business Online
Excerpts: THE library of Alexandria was the first time humanity attempted to bring all human knowledge together in one place at one time. Our latest attempt? Google, according to Brewster Kahle, entrepreneur and founder of the Internet Archive.
Search technology is still in its infancy but it will revolutionise the computer industry and change our world as radically as the PC did a generation ago. The stockmarket hype surrounding the world's leading search engine Google has obscured the fact that Silicon Valley's rising star has only scratched the surface of a technology that is about to transform almost everything we do. Entertainment, publishing and shopping will change forever. Even the PC itself may be unrecognisable.
The Nature Of Personality: Genes, Culture, And National Character, Science
Excerpts: I recently had the opportunity to conduct research in a remote village in the West African nation of Burkina Faso, one of the countries whose national character was studied by Terracciano et al. in a report on page 96 of this issue (1). While there, I was struck by the degree to which everyone seemed so different yet so familiar at the same time. Despite dramatic differences in cultural customs and practices, the Burkinabe people seemed to fall in love, hate their neighbors, and care for their children in much the same way, and for many of the same reasons, as people in other parts of the world. (...)
Excerpts: With new, radical religious movements on the rise globally, why is so much of the world bent on rejecting reason?
ACROSS the world, millions of people feel threatened. They sense a dangerous enemy at the gates, committed to values and beliefs they fear and despise, and ready to impose its alien ideology on their government, their life and their children's futures.
Is that a threat you recognise? If so, then you know how religious fundamentalists feel. To them, the secular world of the early 21st century is a threat to all they hold most dear.
Excerpts: So the secularist may reply to the fundamentalist: "I do indeed have a faith but, unlike yours, it works (?)." The fundamentalist may retort: "We did pray our way to Pentium 4s; you were just deluded in thinking you could make them yourself." You may find his argument implausible, but it is at least complete. If God really does work in mysterious ways, then guiding us to the fabrication of silicon chips may well be one of them. He doesn't necessarily have to restrict Himself to parting the Red Sea.
Inexpert Selection, NY Times
Excerpts: The list of Bush appointees who seem to be rising on political connections rather than expertise continues to grow. A recent example is President Bush's choice to head a key office at the State Department that coordinates the delivery of life-sustaining emergency aid to refugees of foreign wars, persecution and natural disasters. The nominee is Ellen Sauerbrey, the former Maryland state legislator and twice-defeated Republican candidate for governor who was state chairman of Mr. Bush's 2000 campaign.
Cancer Drugs May Help Nerves Regrow, Science Now
Surprising discovery points to new approach to healing spinal cord injuries

The central nervous system in adult mammals is notoriously bad at healing itself. Once severed, the axons that connect one neuron to another can't regrow. That's why people regain little, if any, movement or sensation after a spinal cord injury. Now, researchers have made a promising discovery. In the 7 October Science, they identify a class of drugs--including one already on the market for treating cancer--that promote axon regeneration in rodents.
Signaling: From Stem Cells To Dead Cells, Science
Excerpts: Many scientists are optimistic that the manipulation of stem cells will allow marked advances in the treatment of currently intractable diseases. Realizing the promise of these versatile cells will require understanding of their native control mechanisms. Members of the transforming growth factor- (TGF-) family have emerged as critical regulators of multiple stages in the life of various stem cells (Mishra et al., p. 68). TGF- family members initiate signals that can regulate the proliferation of stem cells in an undifferentiated state, specification of or commitment to a particular developmental lineage, and, in some cases, later differentiation into mature cells. Analogous effects of TGF- family members on proliferation and differentiation are thought to account for their effects on cancer cells.
Micro-Organisms May Be Turned Into Nano-Circuitry, New Scientist
Micro-organisms commonly found floating in oceans might someday be reborn as components in incredibly complex computer circuits.
A scanning electron micrograph reveals the complexity of one diatom (Image: Rex Lowe/BGSU)
The single-celled algae, called diatoms, live in water and assemble a shell, or frustule, of silica by converting nutrients and light. They can adopt an incredible diversity of shapes - from simple geometric structures like triangles and squares to extremely complex 3D constructs with thousands of individual pores.
More than 100,000 different species of diatom are known to exist in nature - some exhibiting features only tens of nanometres (billionths of a metre) in size - and all can rapidly self-replicate through division.
Excerpts: University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping. If the gene is disabled, the worms can't swallow, so they die. If the gene is partly restored so the worms can swallow, they have trouble reproducing and get constipated. "We have found a gene that is important for the control of fundamental rhythms in nematode worms (...) our study suggests this gene and related genes may have critical roles in controlling rhythmic behaviors in humans and other animals." (...)
Resurrected Influenza Virus Yields Secrets Of Deadly 1918 Pandemic, Science
Excerpts: As worries about a new flu pandemic mount, researchers have figured out the traits that made the 1918 influenza virus, which killed between 20 million and 50 million people, so virulent. Although a study on page 77 sheds new light on these questions, it raises a host of others because the researchers reconstructed the complete virus, which no longer existed anywhere on Earth.
The 1918 Flu Virus Is Resurrected, Nature
Excerpts: Some scientists have already hailed the work as giving unprecedented insight into the virus. Working out how it arose and why it was so deadly could help experts to spot the next pandemic strain and to design appropriate drugs and vaccines in time, they say.
But others have raised concerns that the dangers of resurrecting the virus are just too great. (...) And the publication of the full genome sequence gives any rogue nation or bioterrorist group all the information they need to make their own version of the virus.
Microbiology: Conspirators In Blight, Nature
Excerpts: A fungus and a bacterium have been found in a symbiotic alliance that attacks rice plants. (...) the significance of this finding extends beyond its potential agricultural use.
Rice suffers from a serious disease called seedling blight. The cause was thought to be a toxin released by some species of the fungal group Rhizopus. The toxin kills root cells, after which the fungus digests the remains of the dead root. But (...) the toxin is produced not by the fungus, but by bacteria that live in symbiosis inside it.
Nonlinear Dynamics, Granular Media And Dynamic Earthquake Triggering, Nature
Excerpts: The 1992 magnitude 7.3 Landers earthquake triggered an exceptional number of additional earthquakes within California and as far north as Yellowstone and Montana. Since this observation, other large earthquakes have been shown to induce dynamic triggering at remote distances (...). The physical origin of dynamic triggering, however, remains one of the least understood aspects of earthquake nucleation. (...)
Here we show that the dynamic, elastic-nonlinear behaviour of fault gouge perturbed by a seismic wave may trigger earthquakes, even with such small strains.
Volcanoes: Shaken, But Not Stirred, Science Now
Researchers develop model to explain earthquakes that occur before volcanic eruptions.
Deep clues. Magma extruding into the crater of Mount St Helens bears vertical striations that may bear witness to the source of low-frequency earthquakes.
Volcanoes often announce their intentions through low-frequency earthquakes. Now researchers have a new idea how this happens, and the findings may shed light on why some eruptions are much more violent than others.
Volcanic eruptions range from mild to extreme, depending on the kind of molten rock that's underground. When the lava is thick and viscous, it usually bulges out as a harmless dome.
Driverless Robots Reach Milestone In Darpa Race, CNET News.com
Excerpts: Stanford University's Racing Team has accomplished a historic feat of robotics, finishing first in the DARPA Grand Challenge, a 131.6-mile driverless car race that no artificially intelligent machine has ever conquered before.
"We had a great day," said Sebastian Thrun, director of Stanford's artificial intelligence lab and head of the racing team. Stanford's "Stanley," a modified Volkswagen Touareg with sensors and radar mountings, crossed the finish line within eight hours and 14 minutes, beating the 10-hour requirement, according to times posted on the DARPA race Web site.
Robot Vehicles Conquer U.S. Desert Terrain Race, Reuters
Excerpts: Three modified driverless vehicles crossed the finish line and into the history books on Saturday after traversing 132 miles (210 kilometers) of desert terrain, guided only by laser sensors and onboard computers.
No winner was declared yet for the $2 million prize in the race, sponsored by the Defense Advanced Research Projects Agency to spur the development of driverless vehicles that one day could carry water, fuel and other supplies for the U.S. military in war zones.
With Laser 'Ears,' An Effort To Cut Air Traffic Delays, NY Times
Excerpts: As planes mosey 800 feet overhead, on their way to touchdown at Denver International Airport, there is a ghostly roar - caused by turbulence left in the engines' wakes, mostly in the form of two horizontal tornadoes, one near each wingtip.
On bad weather days, it is the fear of those tornadoes, called wake vortexes, that determine how close the next airplane can follow, and that, in turn, determines how many airplanes can land on a runway in an hour.
Media Should Campaign On The Basis Of Facts, Nature
Excerpts: (...) seems to be running a campaign to deny the existence of a link between greenhouse-gas emissions and climate change.
In any country, such campaigns can mislead the public about where the weight of scientific opinion lies.
The scientific community should undoubtedly make every effort to ensure that the public and media know where the weight of scientific opinion lies on issues such as the MMR vaccine, GM foods, HIV and climate change. But surely the media also have a responsibility to find out and convey that information as well?
Theoretical Physicist Aims To Create Ideal Interdisciplinary Environment, Nature
Excerpts: Geoffrey West, President, Santa Fe Institute, Santa Fe, New Mexico
"I was speaking Latin and he was speaking Greek," (...). It took a year of work to get past the jargon, reach across their scientific disciplines and publish a seminal paper in Nature detailing some of the laws that dictate an organism's metabolic rate.
"People don't realize you need to create an atmosphere in which researchers are willing to ask elementary questions without feeling defensive or vulnerable," West says.
He hopes the SFI will continue to fill that void, providing a haven for researchers to explore without boundaries.
Complex Challenges: Global Terrorist Network
Belgium Is Trying To Unravel The Threads Of A Terror Web, NY Times
Excerpts: The case of 18 suspected terrorist sympathizers in Belgium underscores the radicalization of young Muslims in Europe.
On a damp, gray day in March 2004, the Dutch traffic police stopped a Belgian driver for a broken headlight and accidentally stumbled onto a major investigation of Islamic radicals.
The driver was Khalid Bouloudo, a sometime baker and former Ford autoworker born in Belgium. During a routine check, his name turned up on an Interpol watch list, for an international arrest warrant from Morocco charging him with links to a terrorist organization based in Morocco and involvement in suicide bombings in Casablanca in 2003.
N.Y. Threat May Have Been A Hoax, Washington Post
Excerpts: Officials Say Iraqi Informant Disappeared; Alert Has Ended.
The alleged threat that led to heightened security on New York subways last week may have been a hoax on the part of an Iraqi informant attempting to get money in exchange for information, U.S. intelligence and counterterrorism officials said yesterday.
The informant has since disappeared in Iraq, and the Defense Department has not been able to locate him, city and federal officials said.
New York Subway Threat Was A Hoax, Security Sources Admit, Guardian
Excerpts: The alleged terror threat that sparked a big security alert on New York's trains and subway last week turned out to be a hoax concocted by an unreliable US informant in Iraq, it emerged yesterday.
Uniformed and undercover police descended on the city's subway system on Friday after what was described as a "specific threat" that a terror cell was planning to explode bombs concealed in pushchairs, suitcases and rucksacks.
