New research questions basic tenet of neuron function
New findings by researchers at UT Southwestern Medical Center challenge one of the established views of how nerve cells communicate with one another. Every time we move, feel emotions, think or remember, the nerve cells, or neurons, in our body transmit messages to one another via chemical signals called neurotransmitters. Within neurons are tiny organelles called synaptic vesicles that s...Amazon trees much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region. Using radiocarbon dating methods, the team, which includes UC Irvine's Susan Trumbore, found that up to half of all trees greater than 10 centimeters in diameter are more than 300 years old....New evidence questions the simple link between prion proteins and madcow disease
While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life. In addition, the results show that the places in the gut that do take up these disease-associated proteins are different from the locations where infectivity is known to be amplified. The findings will be published in...Tests may help answer questions about GMOs and allergies
The potential of genetically engineered foods to cause allergic reactions in humans is a big reason for opposition to such crops. Although protocols are in place to ask questions about the allergy-causing possibilities, there has been no test that offers definitive answers. But all of that could change as a Michigan State University researcher has developed the first animal model to test w...WARF questions relevancy of documents used to uphold patent challenge

Researchers are questioning the opinion that dairy products provide the necessary dietary calcium required for bone growth.// In a study conducted recently on collected information available that relates to growth of bones in children and adolescence and consumption of dairy products show little or no relationship between the two. Children are often advised to take about 800 to 1500mg...New study questions consumption of milk for bone growth

A team of scientists reports that 'mad cow'-like diseases have not been a major force in human history, nor have been cannibalistic rituals that are known to be associated with disease transmission.// In a new study published by the journal Genome Research, Prof. Jaume Bertranpetit at the Universitat Pompeu Fabra and his colleagues used a fresh set of genetic data to show that balancin...GAO Investigation Questions Validity of DNA Testing Kits
Home DNA testing kits claiming to analyze consumers' DNA for genes which affect diseases like heart disease, cancer, or diabetes are misleading because they provide// results that are ambiguous, medically unproven, or both, according to federal investigators. These were the results from an investigation by the Government Accountability Office (GAO), which has led to a Senate hearing in...African-Americans Pose Less Questions To Treating Doctors
A new study published in the September 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, says that African-Americans are least likely to// ask questions regarding their illness to their doctors. The study says that the level of interest displayed by Caucasian patients in their health is lacking in African Americans. This fact may lead to the African-Americans makin...
