Google Is Adding Major Libraries to Its Database, NY Times
Excerpts: Google's founders, Sergey Brin and Larry Page, have long vowed to make all of the world's information accessible to anyone with a Web browser. The agreements (...) will put them a few steps closer to that goal - (...). Mr. Page said yesterday that the project traced to the roots of Google, which he and Mr. Brin founded in 1998 after taking a leave from a graduate computer science program at Stanford where they worked on a "digital libraries" project. "What we first discussed at Stanford is now becoming practical," (...).
Google's Plan Prompts a Question: What's on the Web?, NPR TOTN
Excerpts: This week, the search engine Google announced plans to digitize millions of library books and make them searchable online. Are we getting closer to the day when most of the world's knowledge is a click away?
A Social Network for Societal-Scale Decision-Making Systems, arXiv
Excerpt: An agent-based simulation demonstrates that in modern representative systems, as the ratio of representatives increases, there exists an exponential decrease in the ability for the group to behave in accord with the desires of the whole. To remedy this issue, this paper provides a novel representative power structure for decision-making that utilizes a social network and power distribution algorithm to maintain the collective's perspective over varying degrees of participation and/or ratios of representation. This work shows promise for the future development of policy-making systems that are supported by the computer and network infrastructure of our society.
One Country, Two Prices? A Study Of The Deflationary Effect Of Price Convergence On Hong Kong, Asian Econ. J.
Excerpt: Consumer prices in Hong Kong at the time of writing have declined by 15 percent from the peak recorded in 1998. We investigate the deflationary impact on Hong Kong of price convergence with the Mainland China, using 1990-2001 annual data on commodity prices in the former and in major cities of the latter. We find evidence of price convergence between the two economies over the past decade. Furthermore, price convergence is estimated to have accounted for one-fifth of the deflation in Hong Kong. (...)
Rapid Progress Reported in Emerging Field of Molecular Electronics, UCLA News
"We have published 64-bit random access memory circuits using bistable rotaxane molecules as the memory elements, (...) at a density of devices that far exceeds current technology," Heath said. "On a Moore's Law graph, our memory circuit is at a density of Intel-like circuits that will be manufactured decades from now." (...)
Representation of molecules called rotaxanes working as switches, this image shows the ˇ§Onˇ¨ state and the ˇ§Offˇ¨ state.
(...) bistable catenanes and rotaxanes work as molecular switches that can be turned on and off when they are attached to surfaces and when they are buried in polymer blends with the consistency of a rubber tire.
Excerpts: A device that automatically detects early symptoms of congestive heart failure has been implanted in a patient in the United States for the first time.
The device is designed to allow patients to get treatment earlier and stay healthier.
When fluid levels around the heart get too high, they can interfere with a normal heartbeat and cause death. The device implanted Monday in 70-year-old Antonio Comandari of Miami monitors the amount of fluid in the chest. If there is a buildup, doctors can prescribe medication to reduce it.
Using Stem Cells for Heart Damage, NPR TOTN
Excerpts: Researchers at Johns Hopkins report that they've had luck in isolating and growing adult stem cells taken from tissue samples, and may be able to use those cells to help generate new tissue to heal the heart after an attack.
Science Finds A Point To Acupuncture, Times
Excerpts: Throughout the 26-week trial participants continued to receive their normal medical care, including anti-inflammatory drugs and pain relievers.
By the eighth week patients who received genuine acupuncture showed a significant increase in function compared with the sham treatment and self-help groups, the research team report in Annals of Internal Medicine. By Week 14, they were also experiencing a significant decrease in pain.
Pain was reduced by about 40 per cent and mobility improved by almost 40 per cent in the volunteers receiving acupuncture.
Excerpt: The speech code is a vehicle of language: it defines a set of forms used by a community to carry information. Such a code is necessary to support the linguistic interactions that allow humans to communicate. How then may a speech code be formed prior to the existence of linguistic interactions? Moreover, the human speech code is discrete and compositional, shared by all the individuals of a community but different across communities, and phoneme inventories are characterized by statistical regularities. How can a speech code with these properties form? We try to approach these questions in the paper, using the "methodology of the artificial".
Building Programmable Jigsaw Puzzles with RNA, Science
Excerpts: One challenge in supramolecular chemistry is the design of versatile, self-assembling building blocks to attain total control of arrangement of matter at a molecular level. We have achieved reliable prediction and design of the three-dimensional structure of artificial RNA building blocks to generate molecular jigsaw puzzle units called tectosquares. They can be programmed with control over their geometry, topology, directionality, and addressability to algorithmically self-assemble into a variety of complex nanoscopic fabrics (...). (...) showing that small RNA structural motifs can code the precise topology of large molecular architectures.

Translation of DNA Signals into Polymer Assembly Instructions, Science
Excerpts: We developed a DNA nanomechanical device that enables the positional synthesis of products whose sequences are determined by the state of the device. This machine emulates the translational capabilities of the ribosome. The device has been prototyped to make specific DNA sequences. The state of the device is established by the addition of DNA set strands. There is no transcriptional relationship between the set strands and the product strands. The device has potential applications that include designer polymer synthesis, encryption of information, and use as a variable-input device for DNA-based computation.
Nucleic Acid Nanotechnology, Science
Excerpts: Nucleic acids are best known as the carriers of genetic information, but they are also a versatile material for designing nanometer-scale structures, because nucleic acid sequences can be designed such that the strands fold into well- defined secondary structures. (...)
Today, two major challenges face nucleic acid-based nanotechnology: to produce complex superstructures from simple molecular building blocks, and to perform controlled mechanical movements in molecular devices. (...). The two studies demonstrate that it will be feasible to build functional materials and devices from "designer" nucleic acids.
Screening For Genetic Disorders: Need To Avoid Anxiety, ESRC
Excerpts: People screened for genetic disorders must have appropriate follow-up and monitoring to avoid stress and anxiety, (...) The research found that identifying individuals as being at risk does not automatically mean that other potentially vulnerable members of the family will be alerted. People picked out as being at risk, but who did not yet have any symptoms, were not unduly anxious about their health, provided they felt they were being monitored and looked after. As a result, they often did not feel the need to pass on information about the condition to blood relatives who might also be at risk. (...)
The Quantum Perfect Storm, Science
Excerpts: Since the 1990s, physicists had found indirect evidence of the giant vortices by studying the magnetization of a tiny superconducting disk in a varying magnetic field, among other techniques. But they inferred the current distribution from computer simulations. Kanda and colleagues probed the currents directly, by placing two tiny electrodes called "tunnel junctions" on the edge of a 1.5-micrometer-wide aluminum disk 120 degrees apart.
(...) monitor and control the positions of vortices in so-called fluxonic devices. Whereas electronic microchips shuttle electrons, fluxonic chips would shuttle vortices, (...).
Protein Engineers Go for Gold, Science
Excerpts: Proteins have become biochemists' favorite Christmas tree, perfect for decorating with all kinds of molecular ornaments. In recent years, teams around the globe have induced the cell's protein factories, called ribosomes, to append protein chains with novel amino acids and other organic groups. Now researchers (...), have managed to get ribosomes to decorate proteins with inorganic gold nanoparticles as well. The development could open the door to new tests of the construction abilities of ribosomes, as well as novel ways to image proteins.
Proteins Come Under New Control, Nature News
Excerpts: Of the tens of thousands of proteins working within a cell, the vast majority are activated or disabled by the addition of a chemical group called a phosphate. This process is vital to control proteins, which together drive everything in our bodies from growth to movement to thought. (...)
A protein steals the phosphate from a molecule called (...) (ATP), with the help of an enzyme called a protein kinase.
(...) reveal an entirely new way in which phosphates are added to proteins, and hence cells' actions may be controlled.
"Pumping" Iron: The Proteins, Science
Excerpts: (...), iron plays a central role in biology. Although iron is vital for life, it is highly reactive and so can be toxic when in excess. Hence, evolution has developed mechanisms to regulate the amount of iron in the cells of our body. (...) stable iron levels are maintained by modulating absorption of iron from the gut. Iron homeostasis is complex, as there are many different proteins that respond not only to the total body burden of iron, but also to stimuli such as hypoxia, (...).
Whence Molecular Electronics?, Science
Excerpts: The drive toward yet further miniaturization of silicon-based electronics has led to a revival of efforts to build devices with molecular-scale components. (...). Some claims may have been exaggerated, but news stories of a crisis in the field are premature. Reports of passive molecular electronics devices, such as tunnel junctions and rectifiers, as well as of active devices, for example, single-molecule transistors and molecular switch tunnel junctions, have withstood scientific scrutiny. Simple molecular electronic devices usually consist of organic molecules sandwiched between conducting electrodes.
'Artificial Life' Comes Step Closer, BBC
(...), small synthetic vesicles that can process (express) genes, resemble a crude kind of biological cell.
The vesicles pushed out a green fluorescent protein
The parts for their "vesicle bioreactors", (...), all come from diverse realms of life.
The soft cell walls are made of fat molecules taken from egg white. The cell contents are an extract of the common gut bug E. coli, stripped of all its genetic material.
This essence of life contains ready-made much of the biological machinery needed to make proteins; the researchers also added an enzyme from a virus to allow the vesicle to translate DNA code.
Digitized and Brought to Life, Washington Post
Excerpts: The larger story, though, is how people are using their digital cameras differently from the film models. Consider the photos snapped by National Guardsmen showing abuse of Iraqi prisoners at Abu Ghraib prison, which were e-mailed widely and shown on national TV. Or the Nashville man who helped police nab the mugger who jumped him at a carwash, by using his cell phone camera to photograph the mugger as he fled.
At home, consumers are embracing all kinds of new camera accessories, (...).
The Astonishing Micropygmies, Science
Excerpts: The discoverers of the Flores micropygmies conclude that they survived on Flores until at least 18,000 years ago. (...) We know that full-sized H. sapiens reached Australia and New Guinea through Indonesia by 46,000 years ago, that most of the large mammals of Australia then promptly went extinct (probably in part exterminated by H. sapiens),(...). We also know that humans have exterminated competing humans even more assiduously than they have exterminated large nonhuman mammals. How could the micropygmies have survived the onslaught of H. sapiens?
Slip Of The Tongue: Word Substitution Mistakes Have More To Do With, ScienceDaily
Excerpts: Why is it that we can look at something, know what it is and still call a rose by a different name? Breaking from conventional wisdom, new research suggests that it isn't a rushed pace or distraction that makes us slip up, but rather a hiccup in how we plan what we're going to say that messes things up. People usually look at things before they name them. For instance, before they say "a hammer," they look at the hammer for a second. But what about when they see a hammer and unintentionally call it "an axe"? (...)
Freak Storms Kill Six In France, BBC
Excerpts: At least six people die and dozens are hurt as hurricane-strength storms hit Paris and much of northern France.
The storm hit Paris without warning and lasted only a few minutes, but caused havoc there and across the north.
The storm caused delays at airports in Paris and brought some train services to a halt. (...)
The gusts of up to 130 km/h (80 mph) prompted the French national weather service, Meteo France, to issue its second-highest alert and warning against people using their cars, (...).
Bipedal Robot Learns To Run, New Scientist
Excerpts: The robot can be said to be running because during each stride both its feet are in the air at the same time. Asimo would not be able to match a human in a sprint, however. The robot is only capable of a restrained 3 km per hour.
Running on two legs is a substantial technical challenge for roboticists because rapidly moving each leg easily upsets a robot's balance. To deal with this problem, Asimo's designers installed two new joints with their own balance sensors in the robot's hips.
Ecobot Eats Dead Flies for Fuel, Wired News
Excerpts: (...) their robot Ecobot II has a stomach consisting of eight microbial fuel cells, or MFCs, that contain bacteria harvested from sewage sludge. (...) the whole system mimics real digestion as closely as possible.
Currently being fed a diet of dead flies and rotten apples, the robot isn't one for speed, though. Ecobot II can crawl along at a top speed of about 2 to 4 centimeters every 15 minutes, fueled by eight flies that are fed directly into the MFCs.
"(...) first robot that actually uses unrefined food," (...).
State-Dependent Foraging Rules For Social Animals In Selfish Herds, Proc. Biol. Sc.
Excerpt: Many animals gain benefits from living in groups, such as a dilution in predation risk when they are closely aggregated (referred to as the 'selfish herd'). Game theory has been used to predict many properties of groups (such as the expected group size), but little is known about the proximate mechanisms by which animals achieve these predicted properties. We explore a possible proximate mechanism using a spatially explicit, individual-based model, where individuals can choose to rest or forage on the basis of a rule-of-thumb that is dependent upon both their energetic reserves and the presence and actions of neighbours. (...)
The Evolution Of Hippocampus Volume And Brain Size In Relation To Food Hoarding In Birds, Ecol. Lett.
Excerpts: Food-hoarding birds frequently use spatial memory to relocate their caches, thus they may evolve a larger hippocampus in their brain than non-hoarder species. (...) In addition, food hoarding may be a cognitively complex task involving elaboration of a variety of brain regions, even outside of the hippocampus. Hence, specialization to food hoarding may also result in the enlargement of the overall brain. In a phylogenetic analysis of distantly related birds, we studied the interspecific association between food hoarding and the size of different brain regions, each reflecting different resolutions. (...) Hence, neural adaptation to food hoarding may favour the evolution of different brain structures.
The Collapse Of Cycles In The Dynamics Of North American Grouse Populations, Ecol. Lett.
Excerpts: Cyclic dynamics of bird and mammal populations are commonly reported in northern latitudes throughout the world, and recent European observations on rodents and grouse suggest that cycle periods decline towards southern latitudes. To investigate latitudinal patterns of cyclic dynamics in North America, we assembled 27 long-term data sets collected between 1939 and 2001 for three grouse species. (...) we show that, in contrast to European studies, North American grouse exhibit period increases from north to south, with cycles collapsing via period lengthening. This occurs because delayed density dependence decreases in southern latitudes, whereas direct density dependence increases. (...)
Breakthrough of the Year, Science
Excerpts: The Breakthrough comprises the new evidence that Mars was once warm, wet, and salty: a candidate environment for early life. (...) Of even wider significance is the demonstrated value of robotic technology (...) for a whole set of exploration and sampling tasks. Indeed, there is now serious talk of rescuing the Hubble Space Telescope with a robot. Other planetary sampling projects made the news in 2004 as well: Cassini, which will drop a probe to evaluate Titan's atmosphere in January; Mars Express, the European mission to sample the Martian atmosphere; (...).
Mars Water Tops Science Honors, BBC News
- Winner: Water on Mars. Nasa's Mars rovers Spirit and Opportunity discovered compelling evidence for the prolonged existence of salty, acidic water on the surface of the Red Planet.
- Runner up: Indonesian "hobbit". (...) new species of human that stood only one metre tall and lived on the Indonesian island of Flores.
- Human cloning. South Korean researchers made headlines across the world after announcing they had cloned human embryos, the first published and "peer reviewed" evidence this technique could work with human cells.
Forecasters Face Losing Key Tools, BBC News
Meteorologists fear they are losing one of their essential forecasting tools - microwave frequencies uniquely able to "see" through clouds from satellites.
Earth observation is being made more difficult
They say commercial applications, for example mobile phones and collision avoidance systems, are ruining them.
The use of the bands in this way causes interference and contaminates the data from the satellites, making it useless.
Not only weather forecasting is put at risk, but also a better understanding of how climate change is developing.
Eavesdropping on Faults to Anticipate Their Next Move, Science
Excerpts: Any active earthquake fault talks to its neighbors, urging some to rupture and cautioning restraint among others. The language of faults is stress (...). Seismologists studying this language of stress have now come out with their most comprehensive attempt to reconstruct past conversations among faults, with an eye toward forecasting where the next moderate to large quakes will strike. Drawing on 160 years of quake history, this latest model builds the most detailed picture yet of present-day crustal stress across the San Francisco Bay area.
Singapore Math Method, NPR TOTN

Excerpts: Stanford mathematician Keith Devlin will moderate a discussion on the subject of infinite numbers at the annual meeting of the American Mathematical Society. He talks about the concept of infinity with NPR's Scott Simon.
Researchers Call For More Materials Science In School, Nature
Excerpts: Last month the National Science Foundation brought 90 teachers to a Materials Research Society meeting in Boston for a symposium on teaching materials science in schools. It has also been expanding its Research Experience for Teachers (RET) programme, (...) to train at materials-science departments in leading universities.
RET programmes have helped teachers develop ways of introducing such topics into the classroom. (...)
But some teachers worry that the No Child Left Behind act, which calls for standardized testing on core subjects, will squeeze out more specialized teaching.
Excerpts: Research published this week in the journal Science indicates that the brain's amygdala keys in on larger-than-normal eye whites as a sign that something's not right.
Human Amygdala Responsivity to Masked Fearful Eye Whites, Science
Excerpts: The amygdala was more responsive to fearful (larger) eye whites than to happy (smaller) eye whites presented in a masking paradigm that mitigated subjects' awareness of their presence and aberrant nature. These data demonstrate that the amygdala is responsive to elements of biologically relevant configural stimuli.
The human amygdala has been shown to be activated robustly by fearful facial expressions in neuroimaging studies, even when expressions are presented with backward masking techniques that decrease the temporal availability of facial expression information and mitigate subjective awareness of their presence.

Buying Into Failure, NY Times
Excerpts: As the Bush administration tries to persuade America to convert Social Security into a giant 401(k), we Americans can learn a lot from other countries that have already gone down that road.
Information about other countries' experience with privatization isn't hard to find. For example, the Century Foundation, at www.tcf.org, provides a wide range of links.
(...) alarm over the large fees charged by some investment companies eventually led government regulators to impose a "charge cap." Even so, fees continue to take a large bite out of British retirement savings.
In Iraq, Less Can Be More, NY Times
Excerpts: Even with the world's most advanced military machine at its disposal, the United States is having remarkable difficulty defeating or even containing the relatively small number of Saddam Hussein loyalists, religious extremists and foreign terrorists in Iraq. Thus the plan to gradually turn security matters over to the Iraqis would seem to be doomed from the start. (...)
The army was a tool for internal repression under Saddam Hussein, and it should not play a prominent internal security role in a democratic Iraq.
Pentagon Blocks MIT Inquiry Into Missile Data Fraud Claims, Nature
Excerpts: The Massachusetts Institute of Technology (MIT) has been forced to abandon a fraud inquiry at one of its laboratories after the Pentagon denied it access to the suspect data.
The university wanted to investigate contentious missile defence tests that took place at its Lincoln Laboratory six years ago. (...).
Pentagon officials say that the test data are classified and cannot be released to an investigatory panel on the grounds of national security. But critics see the Department of Defense stance as a political attempt to block further inquiry into the research.
Complex Challenges: Global Terroist Networks
Bush Signs Law To Unify Control Over Spy Agencies, Globe and Mail Update
Excerpts: Despite different agencies possessing troubling evidence pointing to a pending attack, their failure to exchange information left the United States vulnerable to the worst terrorist strike in history.
Naming a single intelligence chief is intended to break down the bureaucratic turf wars that have long plagued the 15 U.S. intelligence agencies. (...)
Revamping the structure of the U.S. intelligence community won't guarantee security in the murky war against terrorism, (...).
"Instead of massed armies, we face stateless networks," Mr. Bush said. "We face killers who hide in our own cities."
On The Internet, A Web Of Dark Alleys, cnet/NYTimes
Excerpts: "I know that these actions would be controversial in this age where we still think the Internet is a free and open society with no control or accountability," Tenet said, "But, ultimately, the Wild West must give way to governance and control."
Even if the government is able to shore up its networks against attack--one of many goals set forth by the intelligence reform bill passed last week--the ability of terrorists and other dark elements to engage in covert communications online remains a daunting security problem, and one that may prove impossible to solve.
