  1. Science, Uncertainty and Risk: The Problem of Complex Phenomena, APS News online Next Article Bookmark and Share

    Excerpts: Science is increasingly involved in making statements about physical phenomena that influence, and are influenced by, human activities. The discourse among scientists, policy-makers and the public about such phenomena is likely to become increasingly important and increasingly difficult. Climate change is a famous example. There are many more such cases today, and there will be many more in the future. (...) How scientists assess and portray uncertainty in what we say about complex physical phenomena is also difficult and imperfect.

  2. It Will Be a Smaller World After All, NYTimes Next Article Bookmark and Share

    Excerpts: Remember the number 1.85. (...) It should change the way we think about economics, geopolitics, the environment, culture - and about ourselves. To make their calculations orderly, demographers have typically worked on the assumption that the "total fertility rate" - the number of children born per woman - would eventually average out to 2.1. Why 2.1? At that rate the population stabilizes over time: a couple has two children, the parents eventually die, and their children "replace" them. (The 0.1 accounts for children who die before reaching the age of reproduction.)

  3. Stomachs Out of Africa, Science Next Article Bookmark and Share

    Excerpts: Genetic variation within pathogens and parasites provides information about their own evolution but rarely about the evolution of their hosts. Among bacteria, host-parasite coevolution occurs in special cases, but for most bacterial pathogens, frequent transmission between hosts uncouples the evolution of the host from that of the bacterium. However, evidence is accumulating that genes of the bacterium Helicobacter pylori provide information about the origins of their human hosts. (...), Falush and colleagues provide convincing evidence that this bacterium can be used to trace ancient patterns of human migration.

    1. Ulcer Clue? Molecule Could Be Key To Stomach Ailment, Science Next Article Bookmark and Share

      Excerpts: A protein called Ptprz binds with a bacterial toxin to produce ulcers in mice, possibly revealing a mechanism for the disorder.

  4. Archaeology: The Coast Road, Nature Next Article Bookmark and Share

    Excerpts: America's first inhabitants were people from Asia who migrated over a now-submerged land bridge between the two continents. But when did they come, and where did they go after making their crossing? (...) The object (...) is a cave containing specimens that will answer one of the great mysteries surrounding the peopling of the Americas: the date at which the first human colonists crossed from Asia over a land bridge that now lies submerged beneath the Bering and Chukchi Seas, and where the travellers went after that.

  5. Fair Punishment Supports Human Altruism, New Scientist Next Article Bookmark and Share

    Excerpts: The idea of fair punishment helps to maintain altruism in human groups, new experiments have shown. People playing an investing game with real money rapidly abandoned their altruistic behaviour if they felt the punishment given for selfish acts was unwarranted. Human altruism intrigues researchers because evolutionary theory predicts that we should only be kind to others if there is something in it for us. (...) "If people feel the punishment is fair, they respond by cooperating," says Herbert Gintis, (...), but they react very badly to an unfair punishment.

    1. Crows Alter Their Thieving Behavior When Dealing With Kin Or Other Birds, ScienceDaily Next Article Bookmark and Share

      Excerpts: (...) have found a species of crow that distinctly alters its behavior when attempting to steal food from another crow, depending on whether or not the other bird is a relative. The Northwestern crow uses a passive strategy when it attempts to take food from kin but becomes aggressive when it tries to steal a morsel from a non-related crow. "This research shows these birds discriminate kin from non-kin. They can tell who they are related to and treat birds differently. Crows and other corvids are highly complex cognitively and socially, and are very adaptive."

  6. Long Memory In Financial Time Series Data With Non-Gaussian Disturbances, Int. J. of Theor. & Appl. Fin. Next Article Bookmark and Share

    Abstract: We compute finite sample critical values based on non-Gaussian disturbances and the power properties of the tests are compared when using both, the asymptotic and the finite-sample (Gaussian and non-Gaussian) critical values. The tests are applied to the monthly structure of several stock market indexes and the results show that the if the underlying I(0) disturbances are white noise, the confidence intervals include the unit root; however, if they are autocorrelated, the unit root is rejected in favour of smaller degrees of integration.

  7. In Sea Of Cars, Trucks Reveal Traffic Flow, Science News Next Article Bookmark and Share

    Excerpts: Traffic managers in urban settings monitor networks of roadway sensors as one way to detect congestion. The faster those networks recognize problems, the quicker authorities can alert motorists and emergency teams to possible trouble. Now, Benjamin Coifman (...) has devised a way to sense jams more quickly by tracking the motion of trucks or other large vehicles within the overall traffic flow. Amid the torrent of vehicles on highways, he says, those big vehicles stand out much the way breadcrumbs do if dropped into a stream of water.

    1. Benetton Clothing To Carry Tiny Tracking Transmitters, www.sfgate.com Next Article Bookmark and Share

      Excerpts: Clothes sold at Benetton stores will soon contain microchip transmitters that allow the Italian retailer to track its garments from their point of manufacture to the moment they're sold in any of its 5,000 shops. Benetton's introduction of "smart tag" tracking technology will be the largest example of a trend now emerging in the retail industry, according to Phillips Semiconductors, a unit of the Dutch electronics giant that designed 15 million tags being delivered to Benetton this year.

  8. Board Studies Wing Edge, Wind Shear, Foam Repair, Spaceflight Now Next Article Bookmark and Share

    Excerpt: Putting it all together - bipod foam repairs, wind shear, debris impacts, thermal and aerodynamic events - is a complex job. But it may well be a combination of factors doomed Columbia, not any one specific failure. "What we're really looking at is a complex failure of a complex system," Gehman said. "It's possible, one of the scenarios we're looking at, it's possible the foam striking a healthy orbiter would not have done enough damage to cause the loss of this orbiter.

  9. Immunology: Fast And Feel Good?, Nature Next Article Bookmark and Share

    Excerpts: Claims that fasting eases symptoms of autoimmune disease have been met with scepticism. But the idea receives some support from the finding that leptin, a hormone that controls body weight, also regulates autoimmunity. (...) Measles, (...), is renowned for being a more serious disease in populations that are starving or close to starving. Yet many people with the autoimmune diseases rheumatoid arthritis or multiple sclerosis, whose immune systems attack their joints or brain, claim that the symptoms of their disease can be reduced by fasting or a change in diet.

    1. Bone Marrow Cells Can Become Heart Cells, UPI Next Article Bookmark and Share

      Excerpts: Researchers said Tuesday that they have detected the first evidence that cells originating in the bone marrow can form new heart tissue in human adults, adding more support to the potential of using the cells to repair damaged hearts. The study is important because it suggests bone marrow cells called progenitor cells could prove beneficial in the future for repairing heart damage, Dr. Noel Caplice, the Mayo Clinic cardiologist who led the study, said in a written statement.

  10. Psychology Professor Maps Choice-making In The Brain, ScienceDaily Next Article Bookmark and Share

    Excerpts: The latest research (...) may be able to explain why people often can't make up their minds. "This research shows the brain is not a single entity. There is not a single executive decision-making mechanism there." Smith's research has resulted in neuroimages of the parts of the brain used in different types of choices. Smith said there are two systems for making decisions in the brain: deliberative and emotional. Deliberative systems, also referred to as calculation areas, utilize parts of the brain related to mathematics and rational decisions. Emotional systems utilize older, more primal parts of the brain.

    1. Developmental Aspects Of Consciousness: How Much Theory Of Mind Do You Need To Be Consciously Aware?, Conscious. & Cognition Next Article Bookmark and Share

      Abstract: When do children become consciously aware of events in the world? Five possible strategies are considered for their usefulness in determining the age in question. Three of these strategies ask when children show signs of engaging in activities for which conscious awareness seems necessary in adults (verbal communication, executive control, explicit memory), and two of the strategies consider when children have the ability to have the minimal form of higher-order thought necessary for access consciousness and phenomenal consciousness, respectively. The tentative answer to the guiding question is that children become consciously aware between 12 and 15 months (กำ3 months).

    2. World's First Brain Prosthesis Revealed, New Scientist Next Article Bookmark and Share

      Excerpts: The world's first brain prosthesis - an artificial hippocampus - is about to be tested in California. Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing. The prosthesis will first be tested on tissue from rats' brains, and then on live animals. If all goes well, it will then be tested as a way to help people who have suffered brain damage due to stroke, epilepsy or Alzheimer's disease.

  11. The Essence Of Circadian Rhythms, J. Biol. Sys. Next Article Bookmark and Share

    Abstract: A new model (...) is proposed to explain the mechanism of circadian rhythms. The yin yang model separate circadian activities in a circadian system into yin (night activities) and yang (day activities) and a circadian clock into a day clock and a night clock. The day clock is the product of night activities, but it promotes day activities; the night clock is the product of day activities, but it promotes night activities. The clock maintains redox or energy homeostasis of the internal environment and allows temporal separations between biological processes with opposite impacts on the internal environment of a circadian system.

  12. Regulated Portals Of Entry Into The Cell, Nature Next Article Bookmark and Share

    Summary: You are what you eat - and a cell is what it allows through the plasma membrane. All nutrients and signalling molecules have to pass through this barrier, small molecules via protein pumps and channels, larger macromolecules by invagination or endocytosis. It is becoming clear that the molecular interactions governing endocytosis are highly complex and form an integral part of overall cell function. Conner and Schmid review recent research on the routes of entry into the cell, in particular the clathrin pathway and its associated proteins.

    1. State Transitions--a Question of Balance, Science Next Article Bookmark and Share

      Excerpts: Green plants and algae use a process of photochemical energy transduction called photosynthesis to harness light energy to make the energy-rich molecule ATP. Within their chloroplasts, light energy captured by chlorophyll photopigments is transformed into an electrochemical potential, which raises the energy of an electron; the subsequent "fall" of the electron back to its original state releases energy that is used to make ATP. Plants must tune photosynthesis to changing light conditions, and they do this with kinases that phosphorylate (add phosphate groups) to proteins of the photosynthetic machinery.

  13. Evolutionary Biology: Speciation Reversal, Nature Next Article Bookmark and Share

    Excerpts: Chromosome rearrangements within species are thought to contribute to reproductive isolation between species. This has now been shown directly by unrearranging yeast chromosomes to break down a species barrier. Research into evolution is usually a bit like forensic detective work. Because it's impossible to carry out million-year experiments, we instead look at what evolution has produced and try to figure out what happened and why. Nowhere has this been more difficult than in the study of speciation, the process by which one species splits into two.

  14. Universe as Doughnut: New Data, New Debate, Nature Next Article Bookmark and Share

    Excerpts: But, according to the new map, there seems to be a limit to the size of the waves, with none extending more than 60 degrees across the sky. The effect was first noted as a puzzle in the COBE data, (...) and now seems confirmed. If the universe were a guitar string, it would be missing its deepest notes, (...), perhaps because it is not big enough to sustain them. "The fact that there appears to be an angular cutoff hints at a special distance scale in the universe," (...).

    1. Cosmology: Filling In The Background, Nature Next Article Bookmark and Share

      Excerpts: (...) Universe is spatially flat and 14 billion years old, with an energy density consisting of 30% matter and 70% dark energy (a smoothly distributed component that varies slowly, if at all, as the Universe expands). (...) Worse still, why is the total abundance of matter comparable to that of dark energy if they are changing rapidly with respect to each other as the Universe expands? Furthermore, the leading candidate for dark energy is vacuum energy, or the cosmological constant, for which theoretical estimates disagree with observations by 120 orders of magnitude.

  15. The Effects of Cenozoic Global Change on Squirrel Phylogeny, Science Next Article Bookmark and Share

    Summary: Squirrels appear to be excellent indicators of environmental history because they are one of a very small number of mammalian families that is almost worldwide in distribution. Mercer and Roth (p. 1568) present a comprehensive genus-level molecular phylogeny of the squirrel family. They document striking chronological and geographic correspondence between events of divergence and diversification in the squirrel family (Sciuridae) and multiple tectonic, sea-level, and paleontological events documented in the geological record. Their findings may help in the understanding of the Cenozoic environmental and biogeographical history of such complex regions as Southeast Asia and the American tropics.

    1. Inbreeding: Disease Susceptibility In California Sea Lions, Nature Next Article Bookmark and Share

      Excerpts: Inbreeding in animals can increase their susceptibility to pathogens, but direct evidence from wild populations is scarce and it is unclear whether all pathogens are affected equally. Here we analyse rescued California sea lions afflicted with a range of different pathogens, and find that sick animals have higher-than-normal parental relatedness, with the extent varying among disease classes. Our findings indicate that mortality in natural populations may not be entirely random and that inbred individuals could act as more effective reservoirs of infectious agents.

    2. Global Change:Who Pushed Whom Out of the Last Ice Age?, Science Next Article Bookmark and Share

      Excerpt: By most accounts, the North Atlantic called all the shots as the world staggered out of the depths of the previous ice age 20,000 years ago. When warm water surged back into the North Atlantic, the world began to melt out of its deep freeze. When the flow of warm water shut down, the world shivered again. Only after several such reversals did the world break the ice's hold. But now there's an upstart challenging the North Atlantic as a dominant global climate shifter.

  16. Fishy Food Cuts Belching Beasts' Methane, New Scientist Next Article Bookmark and Share

    Excerpts: Adding a dash of fish oil to animal fodder could help farmers stifle the greenhouse gases wafting from their farmyards, (...). Switching animals from regular feed onto a diet of fishy fodder cut the amount of methane in their belches by nearly half. (...) According to the US Environmental Protection Agency, belches from farmyard animals account for around 22 per cent of global emissions of the greenhouse gas methane. Volume for volume, methane traps nearly 20 times as much heat as carbon dioxide, making it a potent contributor to global warming.

  17. Making Faces, NYTimes Next Article Bookmark and Share

    Excerpts: Once removed from a donor, a face, much like a heart, can survive without adequate blood supply for only a matter of hours (...). With the recipient's scar tissue removed and the essential arteries and veins exposed, surgeons would attach them to the corresponding arteries and veins in the harvested face in order to supply both nourishment and drainage. (...). Should a human recipient's subsequent immunosuppression therapy prove successful, they would then face months, even years, of painful healing and physical therapy just to achieve minimal function.

    1. Identical Twins Crack Face Recognition Puzzle, Reuters Next Article Bookmark and Share

      Excerpts: The technology scans and maps the human face as a three-dimensional surface, providing a far more accurate reference for identifying a person than current systems, most of which rely on two-dimensional images, Kimmel said. The product can potentially meet a wide range of security needs (...). Kimmel and one of his former pupils, Assi Elad, had already developed the algorithms used as building-blocks for the face-recognition system. The Bronstein twins constructed a 3-D scanner, together with engineer Eyal Gordon, and applied the ideas to face recognition.

    2. Face-Recognition Technology Improves, NYTImes Next Article Bookmark and Share

      Excerpts: Facial recognition technology has improved substantially since 2000, according to results released yesterday of a benchmark test by four federal government agencies (...). The data, which is the latest in a series of biannual tests overseen by the National Institute of Standards and Technology, is expected to encourage government security officers to deploy facial recognition systems in combination with fingerprinting and other biometric systems for applications like verifying that people are who they claim to be and identifying unknown people by comparing them with a database of images.

    3. Recognizing the Dance on the Dotted Line, NYTimes Next Article Bookmark and Share

      Excerpts: By contrast, in biometric systems the appearance of the signature matters little. Instead, it is the act of signing that counts. (...) The idea of using handwriting dynamics to authenticate signatures is not new. For several years, I.B.M. has sold a system based on the principle to banks and other financial institutions to authorize computer transfers of large amounts of money. But such systems use costly, specially made pens and require the transfer of relatively large amounts of data, making them impractical for retailers with thousands of cash registers.

  18. Just War - or a Just War?, NYTimes Next Article Bookmark and Share

    Excerpts: Profound changes have been taking place in American foreign policy, reversing consistent bipartisan commitments that for more than two centuries have earned our nation greatness. These commitments have been predicated on basic religious principles, respect for international law, and alliances that resulted in wise decisions and mutual restraint. Our apparent determination to launch a war against Iraq, without international support, is a violation of these premises. (...) The war can be waged only as a last resort, (...). In the case of Iraq, (...) alternatives to war exist.

    1. The Right War for the Right Reasons, NYTimes Next Article Bookmark and Share

      Excerpts: There are risks in this endeavor, (...). But no one can plausibly argue that ridding the world of Saddam Hussein will not significantly improve the stability of the region and the security of American interests and values. Saddam Hussein is a risk-taking aggressor who has attacked four countries, used chemical weapons against his own people, professed a desire to harm the United States and its allies and, even faced with the prospect of his regime's imminent destruction, has still refused to abide by the Security Council demands that he disarm.

    1. Judge Affirms Terror Suspect Must Meet With Lawyers, NYTimes Next Article Bookmark and Share

      Excerpts: In a 35-page ruling, the judge showed impatience and irritation with the government over its failure to agree on conditions for a meeting between Mr. Padilla and his lawyers. (...) "Lest any confusion remain," the judge wrote, "this is not a suggestion or a request that Padilla be permitted to consult with counsel, and it is certainly not an invitation to conduct a further `dialogue' about whether he will be permitted to do so."

    2. Forsaken at Guantanamo, NYTimes Next Article Bookmark and Share

      Excerpts: The United States military is holding hundreds of prisoners accused of Taliban or Al Qaeda ties at Guantanamo. Many were seized in the heat of battle, but others were turned over in exchange for rewards or bounties. Advocates for the prisoners maintain that one-third or more are being held on the basis of bad intelligence, (...). Whatever their legal status, the Guantanamo detainees must be given a chance to contest their confinement. Those who were wrongly caught up in the military's net must have an opportunity to make their case.

    3. Measuring Lost Freedom vs. Security in Dollars, NYTimes Next Article Bookmark and Share

      Excerpts: In a notice published last month, the budget office asked experts from around the country for ideas on how to measure "indirect costs" like lost time, lost privacy and even lost liberty that might stem from tougher security regulations. The budget office has not challenged any domestic security rules, and officials say they are only beginning to look at how they might measure costs of things like reduced privacy. But officials said they hoped to give federal agencies guidance by the end of the year.
