(CBS) - For the first time, doctors have been able to objectively measure a person's pain. Researchers from the University of Colorado Boulder exposed test subjects to different levels of heat. Then they analyzed brain scan patterns, and were able to accurately predict the person's pain level with 90 to 100 percent accuracy. Currently, doctors ask patients to measure their own pain – usually using a scale of one to ten. The findings could lead to more reliable ways to detect pain.
(CBS) - A new report is questioning the reliability of neuroscience studies. A team of British researchers reviewed 48 articles that deal with the study of the nervous system and found they had only a 20 percent chance of actually finding the results they were investigating – mostly because the studies were too small. The report said small sample sizes lead to conclusions that could be false or misleading and increasing sample size will help improve accuracy.
(CBS) - Rice imported from certain countries contains high levels of lead that could pose health risks, particularly for infants and children. That's the findings presented at the meeting of the American Chemical Society. Only 7 percent of rice consumed in the United States is imported but rice imports are on the rise. The research found rice from Taiwan and China contained the highest levels of lead.
