This is the first time such a dual function has been demonstrated, shedding new light on the nervous system's information-processing capacity. |
| A Simple Way For Older Adults To Assess Arterial Stiffness: Reach For The Toes
October 7, 2009 at 11:00 pm
|
| How far you can reach beyond your toes from a sitting position -- normally used to define the flexibility of the body -- may be an indicator of how stiff your arteries are. Because arterial stiffness often precedes cardiovascular disease, the results suggest that this could become a quick measure of a person's risk for heart attack or stroke. |

| The High Cost Of Treating Alcohol-impaired Drivers
October 7, 2009 at 11:00 pm
|
| The costs of drinking and driving are all too apparent, with alcohol involved in 41 percent of all motor vehicle crash fatalities in 2006. In addition to the mortality and morbidity, the economic impact of alcohol impaired driving is estimated at $51 billion. Now a new study has found that even minimally injured alcohol-impaired drivers account for higher emergency department costs than other drivers. |

October 7, 2009 at 2:00 pm
|
| Electrical engineers have proposed a new scheme that can overcome a critical limitation of high-resolution electron microscopes: they cannot be used to image living cells because the electrons destroy the samples. The researchers suggest using a quantum mechanical measurement technique that allows electrons to sense objects remotely without ever hitting the imaged objects, thus avoiding damage. |
| New Chemo Cocktail Blocks Breast Cancer Like A Strong Fence
October 7, 2009 at 2:00 pm
|
| A new chemotherapy cocktail cuts the spread of breast cancer by half and is the first drug to attack metastasizing breast cancer. The disease becomes fatal when it travels outside the mammary ducts, enters the bloodstream and spreads to the bones, liver or brain. Currently, there are only drugs that try to stem the uncontrolled division of cancer cells within the ducts. |

Research has made little or no progress on this issue. Two scientists report that the interaction between aerosols, clouds and precipitation is strongly dependent on factors that have not been adequately researched up to now. |

| Sand Dunes Reveal Unexpected Dryness During Heavy Monsoon
October 7, 2009 at 8:00 am
|
| The windswept deserts of northern China might seem an odd destination for studying the heavy monsoon rains that routinely drench the more tropical regions of Southeast Asia. But the sandy dunefields that mark the desert margin between greener pastures to the south and the Gobi Desert to the north are a rich source of information about past climates in Asia. Wetter periods allow vegetation to take root on and stabilize sand dunes. During dry spells, plants die off and the dunes are more active, constantly shifting as sand is blown away and replenished. |

This in spite of the fact that it costs as much as three times more than the much less invasive and equally accurate needle biopsy technique. |
| Electrostatic Surface Cleaning
October 7, 2009 at 12:00 am

October 7, 2009 at 12:00 am
|
| Coastal roads and harbors are traditionally protected from sea erosion by giant blocks of rock or geosynthetic bags filled with material, all locally sourced where possible. In the Arctic and other cold northern regions, where good quality material is often scarce, the prohibitive economic and environmental cost of importing suitable matter has led to a demand for solutions that make use of whatever low quality soil or other material is available. |
| Cooperative Design Shaves Chip-making Costs
October 7, 2009 at 12:00 am
|

| Human Brain, Like Google Maps, Creates Multiple Independent Maps While Finding The Way In Physical World
October 7, 2009 at 12:00 am
|
| Through the power of Google Earth, you can travel the globe from the comfort of your computer screen, peering down on everything from above. But once you change your perspective – if you go into one of the buildings that you've looked down on – you have to upload a new map. Now, researchers in Norway have discovered that the brain also creates multiple independent maps while finding the way in the physical world. |
