Bankruptcy Filings Soar In Advance Of New Law, Washington Post
Excerpts: Two weeks before a new, more restrictive national bankruptcy law goes into effect, financially strapped Americans are rushing to file for protection from their creditors, with filings climbing to an unprecedented average of 13,000 a day last week.
Week after week records are toppled. Last week's 68,287 filings surpassed the record set the week before by 24 percent, and this week's total is likely to be higher, according to data released yesterday by Lundquist Consulting Inc., a financial research firm. #body_type2
Fuel Cells 'Need Political Push', BBC News
Excerpts: The world must actively push for alternative energy technologies such as fuel cells, says Sir David King, the UK government's chief scientific advisor.
But there needs to be a cultural shift in energy production, he told delegates at a fuel cell symposium in London.
Humans had to adapt to climate change, he said, but government could encourage wide adoption of new technologies
Teacher Merit Pay Tied To Education Gains, NY Times
Excerpts: Gov. Mitt Romney of Massachusetts has a bold plan to improve public education in his state. It involves new laptops for students, new science and math teachers and, the most ambitious component of all, merit pay tied to classroom performance that could add $5,000 or more to a teacher's annual salary. "The ability to close the achievement gap is the civil rights issue of our generation," Mr. Romney said in an interview, noting concern over test scores as well as the country's lagging production of scientists and engineers. "This is the way to do it."
Systems Biology: Deviations In Mating, Nature
Excerpts: Why do cells of the same type, grown in the same conditions, look and behave so differently? Studying fluctuations in a well-characterized genetic pathway in yeast hints at how such variation arises.
A glance in a microscope quickly convinces one that cells are strikingly diverse. Even when they share the same genome and are grown in the same environment, individual cells differ in size, shape and response to stimuli. Traditionally, such diversity has been a confounding factor in biology experiments, which seek to discover the precise response (...).
The Human Connectome: A Structural Description Of The Human Brain, PLoS Comput Biol
Excerpts: The connection matrix of the human brain (the human ˇ§connectomeˇ¨) represents an indispensable foundation for basic and applied neurobiological research. However, the network of anatomical connections linking the neuronal elements of the human brain is still largely unknown. While some databases or collations of large-scale anatomical connection patterns exist for other mammalian species, there is currently no connection matrix of the human brain, nor is there a coordinated research effort to collect, archive, and disseminate this important information. We propose a research strategy to achieve this goal, and discuss its potential impact.
Brain Disconnects During Sleep, Science Now
Excerpts: Consciousness fades when brain regions stop talking to each other Before the subjects nodded off, the researchers stimulated a small patch of right frontal cortex with transcranial magnetic stimulation (TMS), a method that uses magnetic pulses to induce an electrical current inside the head. When the subjects were awake, TMS elicited waves of neural activity that spread through neighboring areas of right frontal and parietal cortex and to corresponding regions on the left side of the brain. During non-rapid eye movement (non-REM) sleep, the same TMS stimulus only elicited neural activity at the site of stimulation.

Breakdown Of Cortical Effective Connectivity During Sleep, Science
Excerpts: When we fall asleep, consciousness fades yet the brain remains active. Why is this so? To investigate whether changes in cortical information transmission play a role, we used transcranial magnetic stimulation together with high-density electroencephalography and asked how the activation of one cortical area (the premotor area) is transmitted to the rest of the brain. During quiet wakefulness, an initial response (15 milliseconds) at the stimulation site was followed by a sequence of waves that moved to connected cortical areas several centimeters away.
Widespread Cortical Networks Underlie Memory And Attention, Science
Excerpts: Circumscribed brain lesions can cause some profound but highly specific cognitive losses. One important example is anterograde amnesia, the inability to acquire new memories. This condition has been attributed to lesions in the temporal lobe, one of the major regions of the brain (see the figure). Another example is called neglect, the inability to sense, comprehend, and/or respond to stimuli on one side of space (the side opposite to that of the brain lesion).
Mutant Mice Reveal Secrets Of The Brain's Impressionable Youth, Science
Excerpts: In the malleable young brain, neurons readily adapt to new experiences by changing which cells they connect to and how they communicate with those partners. As the brain matures, it loses much of this neural plasticity and becomes considerably more set in its ways. On page 2222, researchers describe molecular signaling that may bring the brain's impressionable youth to an end. The identity of these maturity molecules may also shed light on the long-standing question of why it's difficult for the mammalian central nervous system to repair itself.
Autoimmune Overload May Damage HIV-Infected Brain, Innovations-report
Excerpts: Researchers studying the evolution of the human immunodeficiency virus (HIV) in the brain have found that the body's own defenses may cause HIV-related dementia. (...) the researchers show that HIV in the temporal lobe mutates at a rate 100 times faster than in other parts of the body, triggering white blood cells to continually swarm to attack the infection. The associated overcrowding and inflammation appear to cause the dementia. (...)
Evolutionary Implications Of The Adaptation To Different Immune Systems In A Parasite With A Complex Life Cycle, Proc. Biol. Sc.
Excerpts: Many diseases are caused by parasites with complex life cycles that involve several hosts. If parasites cope better with only one of the different types of immune systems of their host species, we might expect a trade-off in parasite performance in the different hosts, that likely influences the evolution of virulence. We tested this hypothesis in a naturally co-evolving host-parasite system (...). We did not find a trade-off between infection success in the two hosts. Rather, tapeworms seem to trade-off adaptation towards different parts of their hosts' immune systems. (...)
Mighty Mice Regrow Organs, Wired
Excerpts: Mice (...) have the seemingly miraculous ability to regenerate like a salamander(...).
Researchers systematically amputated digits and damaged various organs of the mice, including the heart, liver and brain, most of which grew back.
The results stunned scientists because if such regeneration is possible in this mammal, it might also be possible in humans.
(...) When cells from the regenerative mice were injected into normal mice, the normal mice adopted the ability to regenerate. And when the special mice bred with normal mice, their offspring inherited souped-up regeneration capabilities.
Thinking Big, Nature
Excerpts: Fritz London's single-minded thinking led him to surpass even Einstein, as he believed correctly that quantum mechanics was right at all scales, including the macroscopic.(...)
He was among the few pioneers who deliberately chose, once atoms and molecules were understood, not to focus his research on further subdividing the atom into its ultimate constituents, but on exploring how quantum theory could work, and be observed, on the macroscopic scale.(...)
(...) became intrigued by the twin phenomena of superfluidity and superconductivity, which, he was convinced, were macroscopic manifestations of quantum mechanics.

Wild Gorillas Pick Up Tools, Science Now
Excerpts: Gorillas have been spotted for the first time using tools in the wild. The observation adds the species to a growing list of animals, including chimpanzees, orangutans, dolphins, and crows, that can use sticks, rocks, and even sponges to help them perform specific tasks.
Scientists had known that gorillas could use tools in captivity, for example to retrieve food or toys that are out of reach, but despite decades of observations, no one had documented them using tools in the wild.
Double Quantum Dot As A Quantum Bit, Science
Excerpts: Quantum dots, solid-state structures that are capable of confining a very small number of electrons, have long been thought of as artificial atoms. With the help of these dots, the tools of device engineering can be used to dissect new atomic physics phenomena. Important advances in recent years have made it routine in several labs to construct the smallest possible dots, each holding exactly one electron. One might expect this artificial "hydrogen" to have extremely simple electronic properties.
Diving Deep Into Quicksand, Science Now
Quicksand has the unsettling property of being easier to get into than out of. Now a new analysis of this treacherous mixture of earth and water may explain why, as well as provide a few survival tips to anyone unlucky enough to get trapped.

On a recent vacation to Iran, Daniel Bonn of the University of Amsterdam in the Netherlands and the ?cole Normale Sup?rieure in Paris came across a warning sign for quicksand next to a salt lake.
Robotics: Self-Replication From Random Parts, Nature
Excerpts: Autonomously self-replicating machines have long caught the imagination but have yet to acquire the sophistication of biological systems, which assemble structures from disordered building blocks. Here we describe the autonomous self-replication of a reconfigurable string of parts from randomly positioned input components. Such components, (...), could constitute self-fabricating systems whose assembly is brought about by the parts themselves.
A key feature of biological replication is a template molecule's ability to make copies of itself (as in the case of DNA) by selecting the appropriate building blocks (nucleotides) (...).
Ten Questions about Emergence, arXiv
Excerpts: Self-Organization is of growing importance for large distributed computing systems. (...) Emergence is widely recognized as the core principle behind self-organization. Therefore the idea to use both principles to control and organize large-scale distributed systems is very attractive and not so far off.
Yet there are many open questions about emergence and self-organization, ranging from a clear definition and scientific understanding to the possible applications in engineering and technology, including the limitations of both concepts. (...)
The Time Is Now: Bust Up the Box!, NY Times
Excerpts: For decades, increases in the speeds of computer networks trailed the exponentially accelerating speed of microprocessor chips. Now the balance between the power of computer processing and networking has fundamentally reversed, and the rapid rise of transmission speeds is beginning to have a revolutionary impact on how computers are used and what...
Working Together, Wherever They Are, NY Times
Excerpts: In the new wave of Internet innovation, companies are embracing the potential of networked computing to let workers share their knowledge more efficiently as they nurture new ideas, new products and new ways to digitally automate all sorts of tasks. Companies are drawing on collaborative models that first blossomed in nonbusiness settings, from...
Professor Wants To Put Your Toaster On The Internet, ScienceDaily
Excerpts: The past 100 years has been The Age of Electricity, says Professor Fei-Yue Wang. During that time, our homes have become increasingly complex and home appliances now have sophisticated internal microprocessors and CPUs. This includes VCRs, TVs, DVD players, telephones, microwaves, dishwashers, CD players and many other devices. (...) In a connected world and for a connect lifestyle, Wang envisions two central controllers - one in the house and another at the appliance company headquarters. "The company headquarters will have a super operation center that will learn the habits from each individual house by various data mining techniques," (...).
What Do TiVo and the Mac Mini Have in Common?, NY Times
Excerpts: Consider word-processing software: through the 80's and early 90's, there were a dozen contenders. Now, for practical purposes, there is only Microsoft Word. (...)
And in the last five years, some breathing room appeared. Every new approach that managed to survive - Adobe document formats, Palm and now BlackBerry mobile devices, FireFox and other browsers, Linux, and Internet-based computing from the likes of Yahoo and Google - suggested that an ever more diverse tech ecosystem was becoming possible. (...)
TiVo deserves similar recognition, (...).
Officials Fear Chaos if Iraqis Vote Down the Constitution, NY Times
Excerpts: Approval "is critically important," a senior administration official said, "to maintain political momentum. That is the critical thing for holding this whole thing together." (...)
Their calculations are complicated, because by law the constitution will fail if it is rejected by two-thirds of the voters in any three of Iraq's 18 provinces, even if a majority of voters nationwide approve it.
In regions dominated by Sunni Arabs, opinion polls have shown sentiment running just about two to one against it.
Complex Challenges: Global Terrorist Network
Physicians Ill-prepared To Diagnose, Treat Bioterrorism Diseases, ScienceDaily
Excerpts: More than one-half of 631 physicians tested were unable to correctly diagnose diseases caused by agents most likely to be used by bioterrorists, such as smallpox, anthrax, botulism and plague, according to a Johns Hopkins study (...). However, test scores improved dramatically for the same physicians after they completed an online training course in diagnosing and managing these diseases caused by bioterrorism agents, according to the study. "Most American physicians in practice today have never seen any cases of these diseases in their practice," explained Sara Cosgrove, M.D., M.S., a faculty member in Hopkins' Division of Infectious Diseases. (...)
Nations Struggle To Infiltrate Al-Qaida, AP/WTOP News
Excerpts: Turkish intelligence agents are infiltrating mosques, monitoring underground Web sites and investigating Islamic front charities but are having little success penetrating al-Qaida's tight-knit cells, agents and anti-terror police say. It is a common frustration around the world, with police in Italy, Britain and dozens of other countries finding it difficult to penetrate al-Qaida, a loosely knit terrorist organization where family ties and close personal relationships are often key.
