Breast ultrasound can help diagnose breast cancer and guide a biopsy, but a new ultrasound technique could determine whether a lump is cancerous based on the elasticity, or stretchiness of the lesion. Elasticity imaging is a modification of regular ultrasound and gauges how the tissue moves and how soft or hard it is. The greater the movement or elasticity the greater the likelihood the lump is malignant. In a study presented at a recent meeting of the Radiological Society of North America the non-invasive ultrasound technique was nearly 100 percent accurate.
You might think that work's a real pain which might be true if you spend your days sitting up straight at your desk. A study by the University of Alberta Hospital in Canada used a special type of MRI called positional MRI to get a view of people sitting at desks. The 90 degree posture which most people use puts the greatest strain on the spine and while slouching is normally frowned upon the most favorable position was slightly reclined with feet flat on the floor.
Kids can't help but make noise when they play but noisy toys are another story. A recent study by NOVA Southeastern University in Florida looked at the so called sound pressure level of children's toys. While toys are supposed to meet mandated decibel levels 70 percent of the toys tested exceeded those levels. Researchers are concerned that regular exposure to high noise levels could lead to permanent hearing loss.
