| Frozen Assets: Decades-old Frozen Infant Stool Samples Provide Clues To Norovirus Evolution
October 11, 2009 at 5:00 pm
|
| A search through decades-old frozen infant stool samples has yielded rich dividends for scientists. They have customized a laboratory technique to screen thousands of samples for norovirus, a major cause of acute gastroenteritis outbreaks in people of all ages. What they discovered about the rate of evolution of a specific group of noroviruses could help researchers develop specific antiviral drugs and, potentially, a vaccine against a disease that is very unpleasant and sometimes deadly. |

| 'No Major Role For Fish' In The Prevention Of Heart Failure, Study Suggests
October 11, 2009 at 5:00 pm
|
| The consumption of fish has no major role in the prevention of heart failure, according to results from a large prospective population study. The study, which was started in 1990 and involved all men and women over the age of 55 living in a suburb of Rotterdam, found no difference in the risk of developing heart failure between those who did eat fish and those who didn't. |
| More Powerful Internet Access On Airplanes And Trains
October 11, 2009 at 5:00 pm

| For the first time, researchers have demonstrated 60 GHz broadband radio for wireless transmission of HD video data, HDTV, live. The findings mean more robust transmissions that are less susceptible to interference. |
| Researchers Probe Computer 'Commonsense Knowledge'
October 11, 2009 at 5:00 pm
|
| Challenge a simple pocket calculator at arithmetic and you may be left in the dust. But even the most sophisticated computer cannot match the reasoning of a youngster who looks outside, sees a fresh snowfall, and knows how to bundle up for the frosty outdoors. For artificial intelligence scientists, enabling computers to have such human-level intelligence requires a commonsense knowledge base that can evolve and learn new things. But it's an elusive goal. |
| Nitrogen Cycle: Key Ingredient In Climate Model Refines Global Predictions
October 11, 2009 at 11:00 am
|
| For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. |
| Enhanced Stem Cells Promote Tissue Regeneration
October 11, 2009 at 11:00 am
|
| Engineers have boosted stem cells' ability to regenerate vascular tissue (such as blood vessels) by equipping them with genes that produce extra growth factors (naturally occurring compounds that stimulate tissue growth). In a study in mice, the researchers found that the stem cells successfully generated blood vessels near the site of an injury, allowing damaged tissue to survive. |
| NIH Prepares To Launch 2009 H1N1 Influenza Vaccine Trial In People With Asthma
October 11, 2009 at 11:00 am
|
| The National Institutes of Health is preparing to launch the first government-sponsored clinical trial to determine what dose of the 2009 H1N1 influenza vaccine is needed to induce a protective immune response in people with asthma, especially those with severe disease. |
| Building A Better Qubit: Combining Six Photons Avoids Quantum Data Scrambling
October 11, 2009 at 11:00 am
|
| The qubits that carry quantum information are typically fragile, but a new method of combing six photons leads to robust qubits that are immune to many of the effects that threaten to scramble quantum data. |
| Where Religious Belief And Disbelief Meet
October 11, 2009 at 11:00 am
|
| While the human brain responds very differently to religious and nonreligious propositions, the process of believing or disbelieving a statement, whether religious or not, seems to be governed by the same areas in the brain. |
| 3-D Structure Of Human Genome: Fractal Globule Architecture Packs Two Meters Of DNA Into Each Cell
October 11, 2009 at 5:00 am
|
| Scientists have deciphered the three-dimensional structure of the human genome, paving the way for new insights into genomic function and expanding our understanding of how cellular DNA folds at scales that dwarf the double helix. The researchers describe a new technology called Hi-C and apply it to answer the thorny question of how each of our cells stows some three billion base pairs of DNA while maintaining access to functionally crucial segments. |
| Gene Data Tool Advances Prospects For Personalized Medicine
October 11, 2009 at 5:00 am
|
| A sophisticated computational algorithm, applied to a large set of gene markers, has achieved greater accuracy than conventional methods in assessing individual risk for type 1 diabetes. The researchers suggest that their technique, applied to appropriate complex multigenic diseases, improves the prospects for personalizing medicine to an individual's genetic profile. |
| Tropical Regions To Be Hardest Hit By Fisheries Shifts Caused By Climate Change
October 11, 2009 at 5:00 am
|
| Major shifts in fisheries distribution due to climate change will affect food security in tropical regions most adversely, according to a new study. |
| NIH Launches 2009 H1N1 Influenza Vaccine Trials In HIV-infected Pregnant Women
October 11, 2009 at 5:00 am
|
| The first clinical trials to test whether the 2009 H1N1 influenza vaccine can safely elicit a protective immune response in pregnant women has just been launched, and a trial to conduct the same test in HIV-infected children and youth will begin mid-October. |
| Vision Influences Adults' Success And Health; Prenatal Factors May Be Crucial
October 11, 2009 at 5:00 am
|
| Impaired vision is associated with unemployment, low socioeconomic status, and general and mental health problems, says a long-term study. Poor vision was also associated with low birth weight, intrauterine growth retardation, maternal smoking during pregnancy, and socioeconomic deprivation in early childhood. The findings held true for all causes and levels of impairment. This is one of the largest studies to examine the impact of visual disability on social and occupational success. |
| Physicists Measure Elusive 'Persistent Current' That Flows Forever
October 11, 2009 at 12:00 am
|
| Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external power source. |
| Banded Rocks Reveal Early Earth Conditions, Changes
October 11, 2009 at 12:00 am
|
| The strikingly banded rocks scattered across the upper Midwestern United States and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than two billion years ago. |
| Ironing Out Genetic Cause Of Hemoglobin Problems
October 11, 2009 at 12:00 am
|
| A gene with a significant effect on regulating hemoglobin in the body has been identified as part of a genome-wide association study, which looked at the link between genes and hemoglobin level in 16,000 people. The research shows a strong association between a gene known as TMPRSS6 and the regulation of hemoglobin. |
| Blood Counts Are Clues To Human Disease
October 11, 2009 at 12:00 am
|
| New research examines that most important and diverse of tissues -- blood -- for genetic markers important in health. The team found 15 new genetic variants associated with diseases including anemia, infection and blood cancers. Among these, they show that one variant associated with heart disease arose and spread in European peoples only 3,400 years ago. Further characterization of the regions uncovered could improve our understanding of how blood cell development is linked with human diseases. |
| World Will Miss 2010 Target To Stem Biodiversity Loss, Experts Say
October 11, 2009 at 12:00 am
|
| The world will miss its agreed target to stem biodiversity loss by next year, according to experts convening in Cape Town for a landmark conference devoted to biodiversity science. Growing water needs and mismanagement are leading to 'catastrophic decline' in freshwater biodiversity, according to experts. | | |
