This week’s New England Journal of Medicine reported that annual chest computed tomography (CT) scans on those at risk for lung cancer can detect it earlier, at a more treatable stage. In the study, more than 31,000 people in the United States and overseas underwent spiral CT scans of their chests at the beginning and again in seven to 18 months unless something was detected on the first scan.
It’s flu season, but it may not be the best time to schedule your child’s flu shot, according to one Penn State physician and researcher. Penn State Milton S. Hershey Medical Center pediatrician Ian M. Paul recently studied vaccination records of two high-risk pediatric groups — infants less than age 2 years and children with asthma — and found that year-round scheduling of flu shot appointments contributes significantly to better vaccination rates.
Bringing hope to hundreds of children in one of the countries hardest hit by HIV/AIDS, the Abbott Fund, Baylor College of Medicine and the Government of Malawi have joined forces to build the country’s first pediatric HIV clinic. The First Lady of Malawi, Madame Ethel Zvauya Mutharika and other dignitaries at Kamuzu Central Hospital officially opened the new clinic today in the city of Lilongwe.
Governor Mike Huckabee of Arkansas and Pfizer Inc today announced the formation of Balance It Out: Arkansas, a new school-based community program to reduce the number of children who are overweight or at risk of becoming overweight, effectively diminishing their risk of developing chronic illness. In December 2006, the program will begin in Little Rock, AR, with a health fair for state employees designed to increase awareness of health risk factors and steps to prevent disease. Beginning in early 2007, the program will reach children and their families in the Dollarway (Pine Bluff), Harrison and Paragould school districts.
In a study published in the November 3 issue of the journal Science, an international group of ecologists and economists shows that the loss of biodiversity is profoundly reducing the ocean’s ability to produce seafood, resist diseases, filter pollutants, and rebound from stresses such as over fishing and climate change.
Fundamental theories regarding consciousness, emotion and quality of life in sufferers of paralysis from Amyotrophic Lateral Sclerosis (ALS, also known as ‘Lou Gerhig’s disease’) are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article reviews the usefulness of currently available brain-computer ?interfaces (BCI), which use brain activity to communicate through external devices, such as computers.
Civil wars have replaced interstate wars as the dominant form of violence in the world and have caused over 16 million deaths since 1945, affecting every region of the planet. A new study, published in International Studies Quarterly, demonstrably shows how an investment in education decreases the likelihood of civil war in any region.
The U.S. Food and Drug Administration (FDA) today announced the results of an investigation by state and Centers for Disease Control and Prevention (CDC) investigators, which found consuming tomatoes in restaurants as the cause of illnesses in the Salmonella Typhimurium outbreak. To date, 21 states have reported 183 cases of illnesses to the CDC.
In a knowledge economy, people work increasingly with their heads instead of their hands. This makes mental health a crucial component of economic growth. However, the knowledge economy leads to high levels of stress and mental health problems. By damaging its “mental capital” the knowledge economy undermines the basis for its own success. These are some of the conclusions of the report “Mental Capital” by Rifka Weehuizen, researcher at UNU-MERIT in the Netherlands.
Physicists from the University of Pennsylvania tackle the fundamental question of how DNA can seemingly violate physics. That is, if DNA is such a rigid molecule, how can it bend and coil without requiring large amounts of force? They used a technique called atomic force microscopy to determine that DNA is much more flexible than previously believed when examined over nano-sized lengths
