  1. In Searching the Web, Google Finds Riches, NYTimes Next Article Bookmark and Share

    Excerpts: Google's newfound power as arbiter of much of the world's digital information, meanwhile, is posing concerns about privacy and fairness, not only from competitors but also from social policy experts and even librarians. Some worry that the company may have become too central in an age when so much vital information is available online. Google says that it goes to great lengths to maintain the privacy of its users and that it refuses to allow advertisers to influence the results of its regular searches.

    1. Plan Would Use Software, Not Devices, to Fight Piracy, NYTimes Next Article Bookmark and Share

      Excerpt: Cryptography Research has begun circulating its proposal, which it calls Self-Protecting Digital Content, among entertainment companies. It plans to make it available publicly this week, in an effort to break the impasse over the Digital Millennium Copyright Act, which Congress passed in 1998 with strong lobbying support from Hollywood and other creators of intellectual property. Cryptography Research's proposal would shift the location of copy-protection code from the consumer products that play music and movies and run software to the content files produced by entertainment companies and software developers

    2. Technology Update: Artificial Intelligence Scopes Out Spam, Network World Next Article Bookmark and Share

      Excerpt: In the cat-and-mouse game of the antispam industry, staying one step ahead of spammers is difficult because they constantly exploit the weaknesses of e-mail keyword filtering. But the newest artificial-intelligence filtering technology may adapt faster than the spammers can alter their messages. (...) Natural-language processors serve as powerful artificial intelligence tools in the fight against spam. These processors, which actually are an array of complex algorithms, scan e-mail messages to discover the content of the messages. The algorithms are packaged into mail-filtering software, which generally sits outside a firewall (...).

  2. Planning for the Next Cyberwar, Wired Next Article Bookmark and Share

    Excerpt: Department of Defense futurists call it network-centric warfare. Other military strategists simply refer to it as the digital war. The first Gulf War was analog, they say. This one was digital. Digital it may have been -- using real-time video images to target missiles in flight, wireless PDAs to connect with stateside medical records from the battlefield, and virtual-reality simulations to provide just-in-time delivery of material to front-line troops. But the nascent version of network-centric warfare waged in Iraq was but a pixilated, low-res harbinger of computer combat to come.

  3. Mind-Machine Merger, Technology Review Next Article Bookmark and Share

    Excerpt: (...) boosting the brain's ability to control external devices, others in the DARPA initiative are aiming to manipulate the brain's inner workings-specifically those that send, receive, and process sights and sounds. By tapping into the visual and auditory regions of the mind, researchers are testing whether such information can be transmitted between brains and computers (...). If successful, the projects could lead to astounding new interfaces that enhance humans' ability to recognize faces, objects, and speech and to make decisions. They might even enable brain-to-brain wireless communication (...).

  4. International Consortium Completes Human Genome Project, NHGRI Next Article Bookmark and Share

    Excerpts: The International Human Genome Sequencing Consortium [...] today announced the successful completion of the Human Genome Project more than two years ahead of schedule.
    Also today, NHGRI unveiled its bold new vision for the future of genome research, officially ushering in the era of the genome.[...]
    The international effort to sequence the 3 billion DNA letters in the human genome is considered by many to be one of the most ambitious scientific undertakings of all time, even compared to splitting the atom or going to the moon.
    "The Human Genome Project has been an amazing adventure into ourselves, to understand our own DNA instruction book, the shared inheritance of all humankind," said NHGRI Director Francis S. Collins, M.D., Ph.D., leader of the Human Genome Project since 1993. "All of the project's goals have been completed successfully - well in advance of the original deadline and for a cost substantially less than the original estimates."
    Contributing Editor's Note: The total funding of the Human Genome Project (1991-2003) has been $3.45 billion. This is roughly equivalent to the cost of only the missiles, bombs, and ammunition used so far by the US in Irak in less than a month; or the actual cost of three months of the ongoing operation in Afghanistan; or one tenth of the total cost of the 1991 Gulf war.

  5. Period Doubling Bifurcation During Onset Of Human Ventricular Fibrillation, Int. J. Bifur. & Chaos Next Article Bookmark and Share

    Abstract: We find evidence of a period doubling bifurcation and transition from pseudo-periodic chaos to a stable limit cycle during onset of ventricular fibrillation (VF) in humans. Novel radial basis modeling techniques are applied to time series of spontaneous VF to estimate time dependent changes in the dynamics. Furthermore, we show that the spectral power content may be used as a surrogate for the underlying bifurcation parameter. With this spectral power measure we demonstrate a characteristic transition from pseudo-periodic chaos to a second pseudo-periodic chaotic regime. The methods described in this paper are generic and applicable to any time series data.

  6. Neurobiology: Dopamine As Chicken And Egg, Nature Next Article Bookmark and Share

    Excerpt: (...) animal trainers to get their animals to perform tricks: follow each successful performance with a tasty snack. This type of learning illustrates the phenomenon of reinforcement, whereby new behavioral responses increase in frequency when they are linked to rewards. At the molecular level, the neurotransmitter dopamine is important in reinforcement; it is released from brain cells in response to natural rewards, including food and during sexual arousal, and most drugs of abuse increase brain dopamine levels. (...) dopamine elicits reward-seeking behavior, as well as signaling when a reward is received.

    1. Subsecond Dopamine Release Promotes Cocaine Seeking, Nature Next Article Bookmark and Share

      Excerpts: The dopamine-containing projection (...) is critically involved in mediating the reinforcing properties of cocaine. (...) Rapid changes in extracellular dopamine concentration were observed at key aspects of drug-taking behaviour in rats. Before lever presses for cocaine, there was an increase in dopamine that coincided with the initiation of drug-seeking behaviours. Notably, these behaviours could be reproduced by electrically evoking dopamine release on this timescale. After lever presses, there were further increases in dopamine concentration at the concurrent presentation of cocaine-related cues.

    2. White Noise Delays Auditory Organization in the Brain, HHMI News Next Article Bookmark and Share

      Excerpts: Exposure to continuous white noise sabotages the development of the auditory region of the brain, which may ultimately impair hearing and language acquisition, according to researchers from the University of California, San Francisco. According to the scientists, the young rats used in their study were exposed to constant white noise that is relevant to the increasing, random noise encountered by humans in today's environment. They theorize that their findings could aid in explaining the increase in language-impairment developmental disorders over the last few decades.

    3. Noise In Eukaryotic Gene Expression, Nature Next Article Bookmark and Share

      Excerpts: Transcription in eukaryotic cells has been described as quantal, with pulses of messenger RNA produced in a probabilistic manner. This description reflects the inherently stochastic nature of gene expression, (...). Here we show in Saccharomyces cerevisiae that stochasticity (noise) arising from transcription contributes significantly to the level of heterogeneity within a eukaryotic clonal population,(...). Furthermore, we explore the propagation of noise in a gene cascade network (...) This result has implications for the role of noise in phenotypic variation and cellular differentiation. Noise In Eukaryotic Gene Expression, William J. Blake, Mads Karn,

  7. Can We Measure Consciousness With EEG Complexities?, Int. J. Bifur. & Chaos Next Article Bookmark and Share

    Abstract: Several complexity measures (...) of EEGs were calculated to distinguish different consciousness levels for different brain functional states. All of the measures decreased with the following order of brain states: rest with eyes open, eyes closed, light sleep and deep sleep. On the contrary, the averaged mutual information between different channels increased significantly during the epileptic seizure; there is no significant difference among the averaged mutual information for the subject resting with eyes open, closed, being in light sleep and in deep sleep. Thus, the former indexes seem to be promising candidates to characterize different consciousness levels, while the latter seems not.

  8. Researchers Get To Grips With Cause Of Pneumonia Epidemic, Nature Next Article Bookmark and Share

    Excerpts: (...) uncertainty surrounding the contributions of the two viruses could be resolved with the aid of direct tests for their presence in patients, to replace the indirect tests for antibodies to the new coronavirus that have been used so far. CDC officials say that they hope to have such a test for the coronavirus ready to send to US state health departments this week. If the coronavirus is shown through animal experiments to be the cause of SARS, a direct test could prove critical to stopping its spread, (...).

  9. Adult Stem Cells to Tackle Multiple Sclerosis, Cordis News Next Article Bookmark and Share

    Excerpts: Researchers at the San Raffaele Hospital in Milan have used injections of stem cells from adult mice to cure mice suffering from the paralysis associated with one form of multiple sclerosis (MS). (...) One million cells were injected into the bloodstreams of 15 paralysed. After 10 days the mice became increasingly active, and four went on to recover full and normal movement. The remaining 11 retained only minor tail paralysis. 'It's a great recovery,' said researcher Angelo Vescovi from San Raffaele's stem cell research institute. The team discovered that the cells had migrated to and repaired damaged nerves and areas of the brain. In particular, they believe that the stem cells were able to replace the fatty myelin coating of brain cells, which are stripped as a result of the disease. More than a million people worldwide suffer from multiple sclerosis, and currently the disease is incurable.

    1. Monkey Cloning Failures Cast Doubt on Feasibility of Human Reproductive Cloning, Scientific American Next Article Bookmark and Share

      Excerpts: Human cloning could face obstacles greater than governmental regulations. [...] reproductive cloning in rhesus monkeys is hindered by the absence of key proteins that control cell division and the splitting of chromosomes. The findings indicate that reproductive cloning of primates, including humans, is unachievable using current techniques.
      [...] despite the fact that [the embryos] appeared to be progressing normally on the surface, none of [them] resulted in a successful pregnancy. On closer inspection, the researchers determined that the cloned monkey embryos were far from normal. Says Simerly: "When cells divide, there are very basic things that are supposed to happen, and they just didn't happen."

  10. Compensation For Wind Drift In Migrating Raptors Is Age Dependent, Biol. Letters & Alphagalileo Next Article Bookmark and Share

    Abstract: Despite huge interest much remains unknown about how wild bird migrants find their wintering areas. Birds of prey seemingly acquire a more sophisticated orientation system through experience. This enables them to detect and compensate for wind drift during later migrations. However, because of this young birds face a risk of failing to reach proper wintering areas in case of rapid climatic wind change. These conclusions are based on the behaviour of birds of prey followed by satellite tracking during migration from NorthEurope to Africa.

  11. The Regressive Ecological Succession By Fractal Analysis Of Plant Spatial Patterns, Ecol. Modelling Next Article Bookmark and Share

    Abstract: We studied the effect of grazing on the degree of regression of successional vegetation dynamic in a semi-arid Mediterranean matorral. We quantified the spatial distribution patterns of the vegetation by fractal analyses, using the fractal information dimension and spatial autocorrelation measured by detrended fluctuation analyses (DFA). Plant spatial patterns were compared over a long-term grazing gradient (low, medium and heavy grazing pressure) and on ungrazed sites for two different plant communities (...). These comparisons provide a quantitative characterization of the successional dynamic of plant spatial patterns in response to grazing perturbation gradient.

  12. Deficits Of Working Memory During Mental Calculation In Patients With Parkinson's Disease, J. Neurol. Sc. Next Article Bookmark and Share

    Abstract: The aim of this study is to establish whether the WM problems in PD are due to reduced attentional set-shifting resources rather than depletion of attention resources. The task design attempts to eliminate confounding of the deficits in dealing with novel material, a problem documented in PD, by concentrating on WM tasks of mental calculation that are familiar to subjects in daily living. (...) the results suggested that the central executive dysfunction in PD during mental calculations was due to reduced attentional set-shifting resources for rapidly alternating operations, rather than the depletion of attentional resources.

    1. Odors Summon Emotion And Influence Behavior, New Study Says, ScienceDaily Next Article Bookmark and Share

      Excerpts: College students frustrated by playing a rigged computer game in a scented room later exhibited that frustration when they inhaled the same smell (...). The study provides further evidence for a growing body of research that indicates emotions can become conditioned to odors and subsequently influence behavior (...). Overall, those participants who took the tests in the room with the computer-game room scent demonstrated less persistence - spending less time on each of the problems they could not solve - than the people who had taken the word tests in the rooms with a different odor or no odor at all.

  13. Evolution: Chromosomal Speciation in Primates, Science Next Article Bookmark and Share

    Excerpts: The divergence of humans from the great apes highlights two of the most debated issues in speciation theory. First, modern humans and their closest relative, the chimpanzee, differ in both gene sequence and chromosome structure, and it is not clear which kind of change was the initial cause of reproductive isolation. (...) chromosomal rearrangements "triggered" speciation by allowing differences under selection to accumulate in genes linked to the rearrangements, despite continued interbreeding between the two lineages for up to 3 million years after their initial divergence (...).

    1. Accelerated Evolution in Rearranged Chromosomes, Science Next Article Bookmark and Share

      Excerpt: Humans and their closest evolutionary relatives, the chimpanzees, differ in ~1.24% of their genomic DNA sequences. (...) We analyzed human and chimpanzee sequence data to search for the patterns of divergence and polymorphism predicted by a theoretical model of speciation. (...) Protein evolution was more than 2.2 times faster in chromosomes that had undergone structural rearrangements compared with colinear chromosomes. (...) These patterns of divergence and polymorphism may be, at least in part, the molecular footprint of speciation events in the human and chimpanzee lineages.

    2. Widespread Cannibalism May Have Caused Prehistoric Prion Disease Epidemics, Science Study Suggests, Science Daily Next Article Bookmark and Share

      Excerpts: Human flesh may have been a fairly regular menu item for our prehistoric ancestors, according to researchers. They say it's the most likely explanation for their discovery that genes protecting against prion diseases -- which can be spread by eating contaminated flesh -- have long been widespread throughout the world.
      The genes, which are mutant versions of the prion protein gene, show key signs of having spread through populations as the result of natural selection [...]. Such mutations, or "polymorphisms," could have provided prehistoric humans a better chance of surviving epidemics of prion diseases, similar to modern day diseases such as Creutzfeld Jacob disease, or kuru.

  14. Superconductivity: Pebbles In The Nodal Pond, Nature Next Article Bookmark and Share

    Excerpt: Although the nodal waves might seem (...) to be quite conventional, there is evidence suggesting that they are much more fragile than the electron waves in normal metals. It appears that they behave like quantum waves only when the system as a whole is in a macroscopic quantum state - that is, when it is superconducting. (...) when the electron energy approaches that of the superconducting gap (associated with the short timescale on which the physics giving rise to superconductivity originates), the STM patterns change in a sudden and dramatic way.

  15. Regime Change In Meteorology, Nature Next Article Bookmark and Share

    Excerpts: Sudden transitions between large-scale atmospheric circulation patterns - kinds of 'punctuated equilibria' - have a deterministic component that can be exploited to identify preferred dynamic cycles. Weather is notoriously unpredictable. But there are many kinds of prediction, and it is possible to make scientific predictions about weather without predicting the weather. A case in point is the common occurrence of 'blocked' patterns of weather, in which the atmosphere remains in much the same state for a week or more, before suddenly switching to another long-lived pattern.

  16. Parallel Universes, Scientific American Next Article Bookmark and Share

    Excerpts: The parallel universes of your alter egos constitute the Level I multiverse. It is the least controversial type. We all accept the existence of things that we cannot see but could see if we moved to a different vantage point or merely waited, like people watching for ships to come over the horizon. Objects beyond the cosmic horizon have a similar status. The observable universe grows by a light-year every year as light from farther away has time to reach us. An infinity lies out there, waiting to be seen.

    1. Saving The Universe By Restricting Research, San Francisco Chronicle Next Article Bookmark and Share

      Excerpt: History's worst technological catastrophes could kill millions or billions of people in this century, and to prevent them, society may need to consider restricting specific types of scientific research, says Sir Martin Rees, Britain's astronomer royal, in the book, "Our Final Hour." His concerns include gray goo (nanobots out of control) and experiments that could create a black hole. "I think the odds are no better than 50-50 that our present civilization on Earth will survive to the end of the present century," Rees says.

  17. Maths Gets Into Shape, Nature Science update Next Article Bookmark and Share

    Excerpts: The Superformula is a modified version of the equation for a circle. Changing one term in the formula varies the proportions of the shape - moving from a round circle to a long and skinny ellipse. Changing another varies the axes of symmetry - shifting from a circle to triangle, square, pentagon and so on. Varying both proportion and symmetry together produces shapes with any number of sides, (...). It can also produce three-dimensional structures, and non-biological shapes such as snowflakes and crystals. "It's a new way of describing nature,"(...).

  18. Visions of Freedom, Dissolved in Chaos, Washington Post Next Article Bookmark and Share

    Excerpts: In three days this week, it seemed as if three years of recent history had been neatly telescoped into a visual allegory. On Wednesday, it was 1989 all over again, a statue coming down, a regime collapsing, wild celebration on the streets; the instant (and premature) analogy was to the end of the Cold War. On Thursday and Friday, the images and the news were snapshots of chaos in its manifold variety: looting, ethnic strife, confrontation between crowds and soldiers, and destruction everywhere. (...) It might have been 1992.

    1. When Freedom Leads to Anarchy, NYTimes Next Article Bookmark and Share

      Excerpts: The Bush administration, ill prepared to curb the lawlessness that has swept Iraq, is reinforcing one of the world's most powerful antidemocratic forces: the fear of chaos. Even as looting subsides, vigilantism flourishes. (...) Unless the United States moves quickly to counter its mistakes, Iraqis are unlikely to trust their security to an open, pluralistic form of government. Public anxiety about disorder has been used to rationalize practically every police state, from left to right, from Moscow to Buenos Aires.

    2. Force Majeure: What Lies Behind The Military's Victory In Iraq, Slate.msn Next Article Bookmark and Share

      Excerpts: (...) promulgated doctrines, field manuals, and war games that envisioned all the services fighting wars together, under command structures that were unified or at least "interoperable." One such document, called "Joint Vision 2020," issued in June 2000, emphasized a strategy of "full-spectrum dominance," involving the conduct of "prompt, sustained and synchronized operations with combinations of forces ... space, sea, land, air and information"-a "synergy of the core competencies of the individual services, integrated into the joint team ... a whole greater than the sum of its parts."

      Abstract: Since 11 September 2001 public advocacy of torture no longer seems taboo. (...) techniques applied to Abu Zubaydah and other Al Qaeda suspects in US custody. This involved ventilation by nasal mask of a paralysed subject, with the ventilator turned off to provide transient suffocation whenever the interrogator was dissatisfied. These included deprivation of food, water, sleep, and light; covering subjects' heads with black hoods for hours at a time; (...) hooking them up to sensors during serial interrogations; and denial of medical attention. At Bagram "disorientation is a tool of interrogation and therefore a way of life."
