So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery. Instead surgeons tend to cut well beyond the visible margins of the lesion in order to be certain they remove all the malignant tissue. Two scientists at Washington University in St. Louis have developed technologies that together promise to solve this difficult problem.

It turns out that watching paint dry might not be as boring as the old adage claims. A team led by Yale University researchers has come up with a new technique to study the mechanics of coatings as they dry and peel, and has discovered that the process is far from mundane.

Several e-reader products on the market today use electrophoretic displays, in which each pixel consists of microscopic capsules that contain black and white particles moving in opposite directions under the influence of an electric field. A serious drawback to this technology is that the screen image is closer to black-on-gray than black-on-white. Researchers at the University of Cincinnati Nanoelectronics Laboratory are actively pursuing an alternative approach for low-power displays.
