I recently had a health journalist interview me about the new guidelines for mammography under 50.
You may recall a storm of controversy was touched off in December 2009, when the US Preventive Services Task Force recommended that mammography begin at 50. Sarah Palin went so far as to compare these recommendations to "death panels" under health care reform. The controversy died down, and health care reform legislation was rewritten to ensure access to mammographic screening.
A study published this week reports that a machine known as magnetoencephalography can correctly identify PTSD 90% of the time. Researchers at the VA in Minneapolis, Minnesota used technology that has been studied for years: imaging the activity of the brain using magnetic sensors. Wikipedia has a nice article about the technique, but it should be noted that the Wikipedia article about Magneto the comic book character is probably longer.»
