  1. Breakthrough Of The Year: Evolution In Action, Science Next Article Bookmark and Share

    Excerpts: (...) 2005 stands out as a banner year for uncovering the intricacies of how evolution actually proceeds. Concrete genome data allowed researchers to start pinning down the molecular modifications that drive evolutionary change in organisms from viruses to primates. Painstaking field observations shed new light on how populations diverge to form new species--the mystery of mysteries that baffled Darwin himself. Ironically, also this year some segments of American society fought to dilute the teaching of even the basic facts of evolution.
    1. Evolution: Is the "Big Bang" in Animal Evolution Real?, Science Next Article Bookmark and Share

      Excerpts: The origin and evolution of animals have remained hotly debated issues ever since Darwin drew attention to the relative paucity of fossils from the Precambrian, which ended 543 million years ago (Mya) (1). On the one hand, a growing collection of exquisitely preserved fossils of soft-bodied animals from the Cambrian has highlighted the existence of Cambrian representatives of most of the living animal phyla (2). This has given rise to the "Cambrian Explosion" hypothesis (3) that most animal phyla arose ~543 Mya within a short period (see the figure).
  2. Stem Cell Controversy: Scientist Is Retracting Landmark Finding, Science News Next Article Bookmark and Share

    Excerpts: A South Korean scientist who claimed to have cloned the first human embryonic stem cell is now requesting that some of his published work be retracted. But as Science News went to press, it was still unclear whether the abrupt turnaround arose from scientific fraud, a laboratory mistake, or both.

    Either way, the fiasco is a setback for stem cell research, other scientists say.

    1. Out, Out Damn Gene!, Science Now Next Article Bookmark and Share

      Excerpts: Scientists have discovered how a common crop pest evades detection. When the invader's cover is blown, the bacterium masks itself by ditching its genetic identification, setting the stage for a quiet and deadly invasion.

      Commonly known as Halo blight, Pseudomonas syringae pv. Phaseolicola infects bean crops. Leaves develop small, water-soaked spots outlined by a yellow halo. As the plants fight back, the tissue around the infection dies, preventing further spread of the blight. But this strategy often fails, and as the bacteria move from leaf to leaf, they usually grow more virulent.

    2. Slowly, Cancer Genes Tender Their Secrets, NY Times Next Article Bookmark and Share

      Excerpts: Jay Weinstein found out that he had chronic myelogenous leukemia in 1996, two weeks before his marriage.

      He was a New York City firefighter, and he thought his health was great.

      He learned that there was little hope for a cure. The one treatment that could save him was a bone marrow transplant, but that required a donor, and he did not have one. By 1999, his disease was nearing its final, fatal phase. He might have just weeks to live.

    3. Gene Therapy: Putting the Fingers On Gene Repair, Science Next Article Bookmark and Share

      Excerpts: Now a technology is emerging that could enable scientists to much more readily repair or alter a cell's existing genes. The key is an engineered protein called a zinc finger nuclease that latches onto a specific gene and snips its DNA. The cell then heals the broken strand using copies of a replacement gene that researchers also supply--in the case of gene therapy, the copies would lack the disease-causing mutation in the original.
  3. New Tamiflu-Resistant Bird Flu Cases Stir Fears, New Scientist Next Article Bookmark and Share

    Excerpts: Fears have been raised over more evidence suggesting that the deadly H5N1 avian influenza can mutate into strains resistant to the frontline flu drug Tamiflu.

    Two more patients with drug-resistant bird flu have been documented by researchers in Vietnam. The two patients, of eight studied, died from H5N1 influenza A, despite treatment with Tamiflu (oseltamivir) having been started early in one of them. The first case of Tamiflu-resistant bird flu was reported in October 2005 .

    1. More Tamiflu Resistance in Bird Flu, Science Now Next Article Bookmark and Share

      Excerpts: The H5N1 avian influenza strain developed strong resistance to oseltamivir, better known as Tamiflu, in two Vietnamese patients who died from the virus early this year, according to a new study. Although not unexpected, the findings offer more evidence that the drug, currently being stockpiled by countries around the world, is likely to be useless in some patients should a bird flu pandemic occur. Researchers say countries should do what they can to minimize that risk--for instance by discouraging people from hoarding the drug.
  4. Synchronization Reveals Topological Scales in Complex Networks, arXiv Next Article Bookmark and Share

    Abstract: We study the relationship between topological scales and dynamic time scales in complex networks. The analysis is based on the full dynamics towards synchronization of a system of coupled oscillators. In the synchronization process, modular structures corresponding to well defined communities of nodes emerge in different time scales, ordered in a hierarchical way. The analysis also provides a useful connection between synchronization dynamics, complex networks topology and spectral graph analysis.
    1. Space And Contact Networks: Capturing The Locality Of Disease Transmission, Interface Next Article Bookmark and Share

      Excerpts: While an arbitrary level of complexity may be included in simulations of spatial epidemics, computational intensity and analytical intractability mean that such models often lack transparency into the determinants of epidemiological dynamics. Although numerous approaches attempt to resolve this complexity-tractability trade-off, moment closure methods arguably offer the most promising and robust frameworks for capturing the role of the locality of contact processes on global disease dynamics. While a close analogy may be made between full stochastic spatial transmission models and dynamic network models, we consider here the special case where the dynamics of the network topology change on time-scales much longer (...).
  5. The Evolution Of Hyperactivity, Impulsivity And Cognitive Diversity, Interface Next Article Bookmark and Share

    Excerpts: The evolutionary status of attention deficit/hyperactivity disorder (ADHD) is central to assessments of whether modern society has created it, either physically or socially; and is potentially useful in understanding its neurobiological basis and treatment. (...) Simulations of the Changing Food group task show that unpredictable behaviour by a minority optimizes results for the group. Characteristics of such group exploration tasks are risk-taking, in which costs are borne mainly by the individual; and information-sharing, in which benefits accrue to the entire group. (...) We conclude that even individually impairing combinations of genes, such as ADHD, can carry specific benefits for society, (...).
  6. Immunology: Jawless Fish Have Form of Adaptive Immunity, Science Next Article Bookmark and Share

    Excerpts: Evolution doesn't like to do things just once. It came up with flight three times, for example--in insects, birds, and bats. Now it appears that evolutionarily distinct immune systems have exploited a similar genetic trick to battle microbes. New research on page 1970 reveals that the immune defenses of jawless fish such as lampreys generate as much diversity as the immune system that organisms from sharks onward in evolution use. And both employ a similar technique: rearranging DNA.
    1. Nervous System's Role In Fatal Heart Rhythm Studied, Innovations-report Next Article Bookmark and Share

      Excerpts: Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, (...). But, by using voltage-sensitive fluorescent dye, injecting it into an isolated animal model and photographing the images at 1,000 frames per second, researchers have been able to see the small picture. These minute images of ventricular fibrillation have recently led to the discovery that the electrical activity during ventricular fibrillation forms distinct patterns. "The patterns aren't random as we previously thought (...). They actually form spiral waves that often collide with each other and spin off more spiral waves."
    2. New Neurons Take Baby Steps In The Adult Brain, Johns Hopkins Medicine Next Article Bookmark and Share

      Excerpts: In experiments with mice, scientists from Johns Hopkins' Institute for Cell Engineering have discovered the steps required to integrate new neurons into the brain's existing operations. For more than a century, scientists thought the adult brain could only lose nerve cells, not gain them, but in fact, new neurons do form during adulthood in all mammals, including humans, and become a working part of the adult brain in mice at the very least.
  7. Age Of Information Overload, CNN/AP Next Article Bookmark and Share

    Excerpts: Not that technology itself won't be important, and search companies are actively seeking better techniques, particularly for audio and video.

    "Social networks, search engines and things yet invented are critical as we bring millions of movies, books and musical recordings online," said Brewster Kahle, a search pioneer who created the Internet Archive, a nonprofit preservation group.

    Even more important will be good research skills -- infoliteracy, if you will. That means knowing where and how to look, and evaluating what you get back.

    1. Satellite Navigation: Europe's Answer to GPS Could Be a Boon for Research, Science Next Article Bookmark and Share

      Excerpts: On 26 December, a European satellite is set to lift off from Baikonur cosmodrome in Kazakhstan and, once in orbit 23,000 kilometers above Earth's surface, start transmitting time signals. Although small--roughly the size of a freezer--the satellite GIOVE-A is the start of something big.

      The craft is the first test bed for Europe's answer to the U.S. Global Positioning System (GPS) satellites. Dubbed Galileo, the European system, like GPS, will consist of a constellation of satellites carrying atomic clocks. A receiver can use their signals to calculate its position to an accuracy of a few meters.

  8. Warped Geometry Speeds Airline Boarding, News@Nature Next Article Bookmark and Share

    Excerpt:
    All aboard: a rush for the window seats might be the quickest way to get everyone on the plane.
    © Getty
    Budget airlines' 'free boarding' policies may produce an indecorous scramble for seats, but don't be too quick to grumble. According to a team of computer scientists and mathematicians, this is one of the most efficient ways to board passengers.
    1. "Going Back to Our Roots": Second Generation Biocomputing, arXiv Next Article Bookmark and Share

      Excerpts: Researchers in the field of biocomputing have, for many years, successfully "harvested and exploited" the natural world for inspiration in developing systems that are robust, adaptable and capable of generating novel and even "creative" solutions to human-defined problems.(...) We believe that a new, inherently inter-disciplinary approach is needed for the development of the emerging "second generation" of bio-inspired methods. This new modus operandi will require much closer interaction between the engineering and life sciences communities (...). We support our argument by examining, in this new light, three existing areas of biocomputing (genetic programming, artificial immune systems and evolvable hardware), as well as an emerging area (natural genetic engineering) (...)
    2. Beyond Barcodes: Complex DNA Taxonomy, Proc. Biol. Sc. Next Article Bookmark and Share

      Excerpts: DNA barcodes can provide rapid species identification and aid species inventories in taxonomically unstudied groups. However, the approach may fail in recently diverged groups with complex gene histories, such as those typically found on oceanic islands. We produced a DNA-based inventory of taxonomically little known diving beetles (...). The study illustrates the difficulties for formal classification in evolutionarily complex lineages, and the potentially misleading conclusions obtained from either DNA barcodes or morphological traits alone. However, the sequence profile of Fijian Copelatus provides an evolutionary framework for the group and a DNA-based reference system (...).
  9. Researchers Develop New Method For Studying 'Mental Time Travel', Princeton University news release Next Article Bookmark and Share

    Excerpts: Neuroscientists at Princeton University have developed a new way of tracking people's mental state as they think back to previous events -- a process that has been described as "mental time travel." The findings, detailed in the Dec. 23 issue of Science, will aid efforts to learn more about how people mine the recesses of memory and could have a wide-ranging impact in the field of neuroscience, including studies of brain disorders such as Alzheimer's disease.
    1. Reindeer Rhythms Run Free, Science Now Next Article Bookmark and Share

      Excerpts: Rudolph, Donner, and Blitzen apparently don't have to worry about jetlag. Unlike most animals and plants, reindeer in the high arctic lose their 24-hour biological clock in summer and winter, according to new research. Animals, plants, and even fungi have an internal timepiece known as a circadian clock that helps them regulate patterns of activity, growth, and metabolism even in the absence of external cues (ScienceNOW, 31 March:).
  10. Maintaining Consumption Styles Means Longer Workdays For U.S. Workers, Connecticut College Press Release Next Article Bookmark and Share

    Excerpts: Those who think that "keeping up with the Joneses" is tough now had better prepare themselves for longer, harder workdays in the future, according to new economic research on income inequality, consumption styles and work hours.

    Samuel Bowles of the Santa Fe Institute and Yongjin Park, assistant professor of economics at Connecticut College, co-authored a study that shows increased income inequality ¡X like that in the United States and in other countries with advanced economies ¡X induces people to work longer hours.

    1. Flogging A Dead Horse, New Scientist Next Article Bookmark and Share

      Excerpts: The harder advertisers strive to get your attention, the more your brain ignores them.

      Jane Raymond is cradling a bottle of mineral water like a baby. She is caressing the sides and cooing over the label. After all it is no ordinary bottle; despite being made of clear plastic it looks as if it has been carved from a block of ice. This simple feature means shoppers are drawn to this bottle over the others on the shelf and cannot resist picking it up, Raymond says. How does she know this? Because she has tested it herself.

    2. Leadership Series: Building a Successful Business, Stabroek News Next Article Bookmark and Share

      Excerpts: The unlikely field of life sciences and the work of Stuart Kauffman of the Santa Fe Institute have shed a light on how organisations and leaders can be more effective by, in essence, becoming complex adaptive systems (CAS). Since Stuart Kauffman's groundbreaking book, "At Home in the .universe," the field of complexity and chaos have been useful lenses with which to look at any highly turbulent dynamic environments, to include the highly turbulent dynamic environments that business leaders find themselves in today.
  11. When A Deathtrap Becomes A Free Lunch, New Scientist Next Article Bookmark and Share

    Excerpts: The enticing insides of a carnivorous pitcher plant is as close as the red crab spider gets to an easy meal, as long as it can get out alive THERE was no splash, just a flash of red as the body plunged into the pool and disappeared. At first, Simon Pollard thought his eyes were playing tricks on him. Spiders don't commit suicide, yet this one - a small red crab spider about a centimetre across - seemed to have thrown itself into the mouth of a carnivorous plant.
  12. Ant Iron Chefs: Larvae Fix Dinner But Don't Sneak Snacks, Science News Next Article Bookmark and Share

    Excerpts:
    ROLE PLAYING. Adults with large heads defend the Pheidole spadonia colony, and the smaller, millimeter-long workers cut up meat from prey and tend the young. The chubby, translucent larvae marinate meat in their digestive juices before the workers distribute it. N. Buck
    Movies of an ant colony show that larvae are the ones that prepare dinner when meat is on the menu. (...)

    Ants prepare their meat not by heating but by marinating it with digestive enzymes to create a glistening protein slurry. With their hourglass figures, adult ants have such tiny waists that solid food can't pass through to their abdomens. Biologists already knew that the blob-shaped larvae predigest meat. Some scientists had suggested that the adults feed meat to the larvae and return later for some regurgitated protein slurry.

  13. Animal Superpowers, New Scientist Next Article Bookmark and Share

    Excerpts: Regrow limbs, hold a breath for ages, use natural night vision, resist radiation, avoid sleep - if animals can do this all the time, then why can't we?

    IMAGINE being able to tell whether a friend had passed by recently just by sniffing the ground. Dogs can do it, so why can't we? Admittedly, they have a bit of an advantage, as their noses contain between 20 and 40 times as many smell receptors. But could we go one better?

    1. The 50 Best Robots Ever, Wired Next Article Bookmark and Share

      Excerpts: They're exploring the deep sea and distant planets. They're saving lives in the operating room and on the battlefield. They're transforming factory floors and filmmaking. They're - oh c'mon, they're just plain cool! From Qrio to the Terminator, here are our absolute favorites (at least for now).(...)

      46. ROOMBA DISCOVERY This wasn't the first robosucker, just the first that didn't blow. In 2005, iRobot's second-generation robotic vacuum showed that domestic bots can actually work. To clean the floors, simply turn the thing on - just try not to stand around watching slack-jawed.

  14. Looking For A Creator's Signature In Space, New Scientist Next Article Bookmark and Share

    Excerpts: If a creator wanted to leave us a message, where would it be? Why, in the cosmic microwave background, of course

    IN DA Bginnin God cre8d da heavens & da earth. If the text message bible makes you cringe, perhaps you'd better stop reading now. Because some physicists believe there is another way to pick up a divine message that will leave traditionalists rolling their eyes to the heavens. Forget scripture, they say, try looking out to space instead.

  15. An Early, Muddy Mars Just Right for Life, Science Next Article Bookmark and Share

    Excerpts: When the Opportunity rover found the salty sedimentary remains of standing water on Mars, the prospects for early life on another planet brightened considerably. Although acid-laden, those early waters were nothing that martian life couldn't have adapted to. It's harder to imagine life originating under such conditions, however. Now, by analyzing the infrared "colors" of the martian surface, planetary scientists have identified clayey rocks that mark an even earlier warm and wet era, one more persistently wet and blessedly less acidic. The origin of martian life now looks brighter too.
    1. Creating First Synthetic Life Form, Globe and Mail Update Next Article Bookmark and Share

      Excerpts: Work on the world's first human-made species is well under way at a research complex in Rockville, Md., and scientists in Canada have been quietly conducting experiments to help bring such a creature to life. Robert Holt, head of sequencing for the Genome Science Centre at the University of British Columbia, is leading efforts at his Vancouver lab to play a key role in the production of the first synthetic life form -- a microbe made from scratch.
  16. Squirt Alert, Science News Next Article Bookmark and Share

    Excerpts:
    MAKE WAY. The peachy-beige amorphous sheets¡Xhighly acidic mats of the invasive sea squirt Didemnum¡Xspread like pancake batter over rocks and any living thing in their path. For scale, white disk at bottom is 2 millimeters in diameter. Whitlatch
    As scientific adviser to a group of Maine watermen, ecologist Larry Harris had heard his share of stories. But one tale, told to him 2 years ago, proved unforgettable. A fisherman related how he had been hauling up a dredge used to scout for scallops in nearby Cobscook Bay when he snagged something novel: a life form resembling blobs of pancake batter.
  17. A Crackling Christmas Mystery, New Scientist Next Article Bookmark and Share

    Excerpts: Stefano Zapperi probably doesn't find the holiday season all that relaxing, but you have to forgive him. The sound of chestnuts roasting on an open fire or a Yule log burning just reminds him of his work.

    Then there's grandma and her never-ending supply of sweets; listening to her unwrap them is no treat. Plus, of course, the holidays mean there are kids around the house, noisily scrunching up the wrapping paper from their presents. In fact, the best gift you could buy Zapperi might be a sturdy set of earplugs.

  18. Mr. Cheney's Imperial Presidency, NY Times Next Article Bookmark and Share

    Excerpts: George W. Bush has quipped several times during his political career that it would be so much easier to govern in a dictatorship. Apparently he never told his vice president that this was a joke.

    Virtually from the time he chose himself to be Mr. Bush's running mate in 2000, Dick Cheney has spearheaded an extraordinary expansion of the powers of the presidency - from writing energy policy behind closed doors with oil executives to abrogating longstanding treaties and using the 9/11 attacks as a pretext to invade Iraq, scrap the Geneva Conventions and spy on American citizens.

    1. Fractal Poverty Traps, World Dev. Next Article Bookmark and Share

      Abstract: This paper offers an informal theory of a special sort of poverty trap, one in which multiple dynamic equilibria exist simultaneously at multiple (micro, meso and/or macro) scales of analysis and are self-reinforcing through feedback effects. Small adjustments at any one of these levels are unlikely to move the system away from its dominant, stable dynamic equilibrium. Governments, markets and communities are simultaneously weak in places characterized by fractal poverty traps. No unit operates at a high-level equilibrium in such a system. All seem simultaneously trapped in low-level equilibria. The fractal poverty traps formulation suggests four interrelated strategic emphases for poverty reduction strategies.

      Excerpts: The commander of American-run prisons in Iraq says the military will not turn over any detainees or detention centers to Iraqi jailers until American officials are satisfied that the Iraqis are meeting United States standards for the care and custody of detainees.

      "Bottom line, we will not pass on facilities or detainees until they meet the standards we define and that we are using today," the commander, Maj. Gen. John D. Gardner of the Army, said in a telephone interview this week from Iraq.

    3. U.S. Airstrikes Take Toll on Civilians, Washington Post Next Article Bookmark and Share

      Excerpts: U.S. Marine airstrikes targeting insurgents sheltering in Iraqi residential neighborhoods are killing civilians as well as guerrillas along the Euphrates River in far western Iraq (...).

      U.S. Marines in Anbar say they take pains to spare innocent lives and almost invariably question civilian accounts from the battleground communities. They say that townspeople who either support the insurgents or are intimidated by them are manipulating the number of noncombatant deaths for propaganda -- a charge that some Iraqis acknowledge is true of some residents and medical workers in Anbar province.

    1. Court Bars Transfer of Padilla To Face New Terrorism Charges, Washington Post Next Article Bookmark and Share

      Excerpts: A federal appeals court yesterday refused to authorize the transfer of "enemy combatant" Jose Padilla to face new criminal charges, issuing a strongly worded opinion rebuking the Bush administration and its handling of the high-profile terrorism case.
    2. Time for Chemical Plant Security, NY Times Next Article Bookmark and Share

      Excerpts: It is hard to believe, but more than four years after the Sept. 11 attacks, Congress has still not acted to make chemical plants, one of the nation's greatest terrorist vulnerabilities, safer. Last week, Senators Susan Collins, a Maine Republican, and Joseph Lieberman, a Connecticut Democrat, unveiled a bipartisan chemical plant security bill. We hope that parts of the bill will be improved as it works its way through Congress, though even in its current form the bill would be a significant step.
