| Simple Brain Mechanisms Explain Arbitrary Human Visual Decisions Posted: 10 Nov 2008 10:00 AM CST Scientists report that a simple decision-making task does not involve the frontal lobes, where many of the higher aspects of human cognition, including self-awareness, are thought to originate. Instead, the regions that decide are the same brain regions that receive stimuli relevant to the decision and control the body's response to it.  |
| Flu Shots May Cut Risk Of Blood Clots Forming In Veins Posted: 10 Nov 2008 10:00 AM CST Flu shots may reduce the risk of blood clots forming in veins by 26 percent. Flu shots may be more protective before age 52.  |
| Intelligent Walker Designed To Assist The Elderly And People Undergoing Medical Rehabilitation Posted: 10 Nov 2008 10:00 AM CST Researchers have designed an intelligent walker (i-Walker) that goes a step beyond conventional walkers as it can communicate with the user, think for itself and react to the environment. The device can understand a set of voice commands and can be activated by means of simple verbal instructions given by the user (e.g., "take me to the kitchen"). To do this, it includes elements for independent movement and a personalized intelligent software agent.  |

| Racial Disparities Increasing For Cancers Unrelated To Smoking, Study Finds Posted: 10 Nov 2008 10:00 AM CST A new American Cancer Society study finds that recent progress in closing the gap in overall cancer mortality between African-Americans and whites may be due primarily to smoking-related cancers, and that cancer mortality differences related to screening and treatment may still be increasing.  |
| Global Warming Predicted To Hasten Carbon Release From Peat Bogs Posted: 10 Nov 2008 07:00 AM CST Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.  |
| Harnessing Nature’s Diagnostic Tools For Disease Prevention Posted: 10 Nov 2008 07:00 AM CST The earlier cancer is diagnosed, the better the chance of effecting a cure. A revolutionary new hybrid technology offers the possibility of detecting this and other diseases right at inception.  |
| DNA Provides 'Smoking Gun' In The Case Of The Missing Songbirds Posted: 10 Nov 2008 07:00 AM CST DNA evidence shows conclusively that males from a North American warbler species interbred with females from a related species and took over a large part of the other species' range.  |
| XDR-TB: Deadlier And More Mysterious Than Ever Posted: 10 Nov 2008 07:00 AM CST New research has found that extensively drug-resistant tuberculosis is increasingly common and more deadly than previously known. Extensively drug-resistant tuberculosis is a growing public health threat that is only just beginning to be understood by medical and public health officials.  |
| Plant Virus Spreads By Making Life Easy For Crop Pests Posted: 10 Nov 2008 07:00 AM CST In 752, Japanese Empress Koken wrote a short poem about the summertime yellowing of a field in what is thought to be the first account of a viral plant disease. More than 1,250 years later, scientists concluded that the virus Koken described was part of the particularly insidious geminivirus family that continues to decimate tomato, tobacco and cotton crops worldwide.  |
| Mental Health Linked To Stillbirth And Newborn Deaths Posted: 10 Nov 2008 07:00 AM CST Women with a history of serious mental illness are much more likely to have babies that are stillborn or die within the first month of life, new research reveals.  |
| How Evolution Learns From Past Environments To Adapt To New Environments Posted: 10 Nov 2008 04:00 AM CST The evolution of novel characteristics within organisms can be enhanced when environments change in a systematic manner, according to a new study. Researchers suggest that in environments that vary over time in a non-random way, evolution can learn the rules of the environment and develop organisms that can readily generate novel useful traits with only a few mutations.  |
| Better Treatments For Inherited Form Of Colon Cancer? Posted: 10 Nov 2008 04:00 AM CST Researchers believe they may be one step closer to understanding how certain forms of colon cancer develop.  |
| Project Virtually Rebuilds Lost Architecture Of The Shakers Posted: 10 Nov 2008 04:00 AM CST The Shakers, a religious group that built 19 communities in the United States during the 1800s, had a prolific and distinct architectural construction and design style. Much of that architecture has been lost; however, a new research project aims to rebuild it -- virtually.  |
| Posted: 10 Nov 2008 04:00 AM CST A study among Baltimore inner-city teenage girls treated for pelvic inflammatory disease shows they are highly vulnerable to subsequent sexually transmitted infections -- sometimes within a few weeks or months of their treatment.  |
| New Technology Promises Cheap Satellite Triple-play Posted: 10 Nov 2008 04:00 AM CST A new technology promises to dramatically lower the costs of satellite bandwidth, potentially bridging the digital divide and enabling satellites to deliver TV, internet and telephony services via satellite. The technical problems are solved, now the research team is working hard on the business case.  |
| Transplant Experts Discuss Organ Trafficking Posted: 10 Nov 2008 04:00 AM CST With the number of patients in need of organ transplants on the rise, an increasing number of patients are turning to unconventional sources for organs. Individuals are willing to donate their kidneys for financial incentive, particularly in developing countries where the poverty rate is high, resulting in numerous reports of human trafficking as a source of organs.  |
| When It Comes To Sea Level Changing Glaciers, New NASA Technique Measures Up Posted: 10 Nov 2008 01:00 AM CST Scientists have used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.  |

| Long-term Benefits Of Morphine Treatment In Infants Confirmed In Rodent Study Posted: 10 Nov 2008 01:00 AM CST Scientists have demonstrate that administration of preemptive morphine prior to a painful procedure in infancy blocks the long-term negative consequences of pain in adult rodents. These studies have serious implications for the way anesthetics and analgesics are administered to neonates prior to surgery.  |
| Polarized Light Guides Cholera-carrying Midges That Contaminate Water Supplies Posted: 10 Nov 2008 01:00 AM CST Midges harbor the lethal Vibrio cholerae bacteria that spreads cholera, contaminating water supplies with the infection when they lay their eggs. What guides the midges to select particular watercourses when laying their eggs? Scientists have found that the midges are attracted by polarized light reflections from water and suggest that polarized light could be used to control cholera transmission and reduce midge numbers.  |
