Modeling, Computation, Simulation

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy — a specialized imaging technique that looks for a change in the color of intense laser light — researchers can collect data on how the light interacts with the sample and, through time-consuming and sometimes expensive analyses, characterize the material’s structure and other properties. Now, researchers at Penn State have developed a computational framework that can interpret the nonlinear optical microscopy images to characterize the material in microscopic detail.

UNIVERSITY PARK, Pa. — Neurons, which are responsible for producing the signals that ultimately trigger an action like talking or moving a muscle, are built and maintained by classes of motor proteins that transport molecular cargo along elongated tracks called microtubules. A Penn State-led team of researchers uncovered how two main groups of motor proteins compete to transport cargo in opposite directions between the cell body and the synapse in neurons.
