Imaging with light & sound: revolutionizing early cancer detection

For years, the field of optical imaging in biological tissue had languished, with few advances and no significant growth. The concept was promising — using light to image organs, cells, and blood vessels, noninvasively and without any radiation — but it seemed impossible to obtain high-resolution images at any significant depth. Then came Lihong V. […]

Mental maturity scan tracks brain development

Five minutes in a scanner can reveal how far a child’s brain has come along the path from childhood to maturity and potentially shed light on a range of psychological and developmental disorders, scientists at Washington University School of Medicine in St. Louis have shown.
