Researchers develop computer model to study cell membrane dynamics A cell constantly remodels its fluid membranes to carry out critical tasks, such as recognizing other cells, getting nutrients or sorting proteins. Because membranes are fluid and intrinsically disordered, investigating these and other life-sustaining processes in detail has always been difficult. But a computer model developed by Markus Deserno, associate professor of physics at Carnegie Mellon University, provides a new approach by allowing him to simulate and observe membrane dynamics at a relatively large scale -- hundreds of nanometers. It is at this scale that many critical membrane-mediated processes take place.
