Webb and Tobias Baumgart, along with National Institute of Child Health & Human Development researcher Samuel T. Hess, use high-resolution fluorescence imaging and two preferentially labeling dyes (red for disordered lipid phases, blue for ordered lipid phases) to image coexisting fluids in biomembrane models [Nature, 425, 821 (2003)]. The technique lets the researchers study the membranes' curvature and line tension, and it could shed light on how actual cell membranes behave in vivo. The 2-D cross-section images on the left demonstrate the influence of tension along the phase boundary, while the other images are some of the fascinating membrane patterns that the team observed.—BETHANY HALFORD IMAGES COURTESY OF WATT W.
